Abstract

A fertilizer grinding mechanism, a water and fertilizer mixing device, and an aqueous fertilizer solution preparation production line. A fertilizer receiving body, where an edge is provided with a arranged first channel; a connecting body, fixed to a bottom of the fertilizer receiving body and provided with a second channel with the first channel, a bottom of the second channel is communicated with a buffer bin, a pushing block is arranged in the buffer bin, and the pushing block is connected with a drive mechanism for driving the block to move in direction of the body; and an inner grinding block, where the block is fixed to a bottom of the connecting body, an outer side of the inner grinding block is with a vertically movable grinding roller, the pushing block can push fertilizer under vertical movement of the roller. The grinding mechanism has a heat dissipation effect.

First claim

What is claimed is:

1. A fertilizer grinding mechanism, comprising:
a fertilizer receiving body, wherein an edge of the fertilizer receiving body is provided with a vertically arranged first channel;
a connecting body, wherein the connecting body is fixed to a bottom of the fertilizer receiving body and provided with a second channel communicated with the first channel, a bottom of the second channel is communicated with a buffer bin, a pushing block is arranged in the buffer bin, and the pushing block is connected with a drive mechanism for driving the pushing block to move in a radial direction of the connecting body; and
an inner grinding block, wherein the inner grinding block is fixed to a bottom of the connecting body, an outer side of the inner grinding block is provided with a vertically movable grinding roller, the pushing block can push fertilizer falling into the buffer bin to a gap between the inner grinding block and the grinding roller so that the fertilizer is ground under vertical movement of the grinding roller.

2. The fertilizer grinding mechanism according to claim 1 , wherein the drive mechanism comprises a pushing column, a top end of the pushing column is connected with a first vertical drive member, the pushing column is hinged to one end of a pull rod, the other end of the pull rod is hinged to the pushing block, a bottom end of the pushing column can be in contact with the pushing block via an arc surface so that vertical movement of the pushing column can be converted into movement of the pushing block in the radial direction of the connecting body.

3. The fertilizer grinding mechanism according to claim 1 , wherein a second vertical drive member is fixed to an outer peripheral surface of the connecting body, the second vertical drive member is connected with a grinding roller support, and the grinding roller is mounted on the grinding roller support.

4. The fertilizer grinding mechanism according to claim 3 , wherein the second vertical drive member is connected with the grinding roller support via a fine-adjusting mechanism, the fine-adjusting mechanism can drive the grinding roller support to move in the radial direction of the connecting body so that a distance between the grinding roller and an outer side surface of the inner grinding body can be adjusted.

5. The fertilizer grinding mechanism according to claim 1 , wherein cooling liquid flow passages communicated with each other are arranged in the connecting body and the inner grinding block.

6. A water and fertilizer mixing device, comprising a crushing mechanism, the fertilizer grinding mechanism according to claim 1 , a fertilizer dispersing mechanism, and a mixing mechanism;
wherein the crushing mechanism is arranged above the fertilizer grinding mechanism and is configured to crush fertilizer and feed the crushed fertilizer to the fertilizer grinding mechanism, the fertilizer dispersing mechanism is fixed to a top of the mixing mechanism and arranged below the fertilizer grinding mechanism, the fertilizer dispersing mechanism is configured to introduce the ground fertilizer into the mixing mechanism, and the mixing mechanism is configured to mix the ground fertilizer and water.

7. The water and fertilizer mixing device according to claim 6 , wherein the fertilizer dispersing mechanism adopts a shell structure, the inner grinding block extends into the fertilizer dispersing mechanism, a bottom of the fertilizer dispersing mechanism is of an inverted cone-shaped structure, a bottom end of the inverted cone-shaped structure is provided with a discharge port, and the fertilizer dispersing mechanism is communicated with the mixing mechanism via the discharge port.

8. An aqueous fertilizer solution preparation production line, comprising: the water and fertilizer mixing device according to claim 7 , a solution feeding device, and a solution diluting device arranged in sequence, wherein the solution feeding device can receive an aqueous fertilizer solution fed from the water and fertilizer mixing device, and feed the aqueous fertilizer solution to the solution diluting device, and the solution diluting device is configured to dilute the aqueous fertilizer solution.

9. The aqueous fertilizer solution preparation production line according to claim 8 , wherein the solution feeding device comprises a pushing shell, a discharge hole of the pushing shell is communicated with the solution diluting device, a feeding hole is connected with the water and fertilizer mixing device, a pushing member capable of moving along an axis of the pushing shell is arranged in the pushing shell, an elastic member is arranged between the pushing member and the pushing shell, an end of the pushing member extending out of the pushing shell is in sliding contact with a lever via a first sliding groove arranged in the lever, one end of the lever is hinged to a positioning block, the other end of the lever is provided with a second sliding groove, a hinge shaft is slidably connected into the second sliding groove, the hinge shaft is hinged to a first rack, and the first rack is meshed with a rotatable first gear.

10. The aqueous fertilizer solution preparation production line according to claim 8 , further comprising a nutrient solution supply device, wherein the nutrient solution supply device comprises a buffer container, the buffer container is communicated with a discharge pipe, a pushout component is arranged in the buffer container, the pushout component can be in contact with a vertically movable second rack, the second rack can discharge a nutrient solution in the buffer container via the discharge pipe by the pushout component, and the second rack is meshed with a rotatable second gear.
