Description

Technical Field

[0001] The utility model relates to the technical field of fertilization, in particular to a fertilizer crushing and spreading device for saline-alkali land. Background Art

[0002] Saline-alkali land is a type of salt accumulation, which means that the salts contained in the soil affect the normal growth of crops. The formation of alkali soil and alkalized soil in China is mostly related to the accumulation of carbonates in the soil, so the alkalization degree is generally high. The traditional improvement methods for saline-alkali land generally proceed in several steps. First, drain salt, wash salt, and reduce the soil salt content. Then plant salt-tolerant plants to fertilize the soil. Finally, plant crops. Improve the soil composition and structure, enhance the soil permeability performance through deep plowing, land leveling, adding filling soil, covering grass, turning silt, covering sand, and increasing the application of organic fertilizers. However, when applying organic fertilizers traditionally, most are applied manually, and the fertilization efficiency is low.

[0003] The patent with the publication number CN213755673U discloses a fertilizer crushing and spreading device for saline-alkali land. It finely crushes fertilizers by setting a motor to drive a crushing roller. The crushed fertilizers enter a screw conveyor, and then a vibration motor drives the material box to vibrate. Under the action of vibration, the fertilizers entering the material box are evenly distributed onto the soil through evenly distributed spreading hoppers below. However, when using this device, it is impossible to ensure that the fertilizers in the material box can be evenly distributed into multiple second connecting hoses, so there will be a situation where some spreading hoppers spread more fertilizers and some spread less fertilizers, resulting in uneven fertilization. Moreover, the fertilization area is only within the span area of the device, and the fertilization range is small. In addition, only using the crushing roller to squeeze the fertilizers can break large particles of fertilizers, but the fertilizers after extrusion will be compacted, and it cannot ensure that the fertilizers are completely crushed and uniform. Therefore, further improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a fertilizer crushing and spreading device for saline-alkali land.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A fertilizer crushing and spreading device for saline-alkali land, including a vehicle board, on the upper surface of which a material barrel is fixed.

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] As Figures 1-3 shown, it relates to a device for crushing and spreading fertilizers on saline-alkali land, including a vehicle board 1. A material barrel 2 is fixed on the upper surface of the vehicle board 1. A conical hopper 3 is fixed inside the material barrel 2. A first blanking pipe 4 is fixed at the bottom of the conical hopper 3. Two symmetric crushing rollers 5 are arranged below the first blanking pipe 4 inside the material barrel 2. A first motor 6 for driving the two crushing rollers 5 to rotate is installed outside the material barrel 2. A crushing knife 7 is arranged below the two crushing rollers 5 inside the material barrel 2. The bottom of the material barrel 2 is designed in a conical shape, and a second blanking pipe 8 is fixed at the bottom of the material barrel 2. The bottom end of the second blanking pipe 8 is hermetically and rotatably connected to an elbow pipe 9. A driving assembly 11 for driving the crushing knife 7 and the elbow pipe 9 to rotate is commonly installed on the bottom wall of the material barrel 2 and the upper surface of the vehicle board 1.

[0023] The vehicle board 1 is provided with a reserved opening 101 below the material barrel 2.

[0024] The reserved opening 101 is provided for the second blanking pipe 8 and the driving component 11 to pass through.

[0025] A solenoid valve 41 is installed in the middle of the first blanking pipe 4.

[0026] By opening or closing the solenoid valve 41, the opening or closing of the first blanking pipe 4 can be controlled to achieve blanking or stop blanking.

[0027] The central axes of the two crushing rollers 5 are rotatably connected to the side wall of the material barrel 2 through bearings. Fixed connection linkage gears 15 are provided on the central axes of the two crushing rollers 5 passing through the side wall of the material barrel 2. The two linkage gears 15 are meshed with each other. The driving end of the first motor 6 is fixedly connected to the central axis of any one of the crushing rollers 5.

[0028] Since the two linkage gears 15 are meshed with each other, when the first motor 6 drives one of the crushing rollers 5 to rotate, the other crushing roller 5 will rotate in the opposite direction, and the two crushing rollers 5 will extrude and crush the fertilizer discharged from the first blanking pipe 4.

[0029] The driving component 11 includes a vertical shaft 113 passing through the bottom wall of the material barrel 2 and rotatably connected to the bottom wall of the material barrel 2. The top end of the vertical shaft 113 is fixedly connected to the crushing knife 7. The bottom end of the vertical shaft 113 is fixedly connected with a driving circular gear 115. A driven circular gear 10 is fixedly connected to the top surface of the elbow pipe 9. The driven circular gear 10 is meshed with the driving circular gear 115. The driving component 11 further includes a second motor 111 fixed on the upper surface of the vehicle board 1. The driving end of the second motor 111 is fixedly connected with a driving bevel gear 112. A driven bevel gear 114 is fixedly connected to the middle of the vertical shaft 113. The driven bevel gear 114 is meshed with the driving bevel gear 112.

[0030] Driven by the driven bevel gear 114 and the driving bevel gear 112, the second motor 111 will drive the vertical shaft 113 to rotate, so as to realize the rotation of the crushing knife 7. The crushing knife 7 can further crush the fertilizer extruded by the two crushing rollers 5. In addition, the bottom of the vertical shaft 113 will drive the driven circular gear 10 to rotate through the driving circular gear 115, and then drive the elbow pipe 9 to rotate, and use the elbow pipe 9 to throw out the fertilizer.

[0031] A plurality of wheels 12 are installed on the lower surface of the vehicle board 1. A handle 13 is fixed on one side of the upper surface of the vehicle board 1. The device can be pushed to move through the handle 13.

[0032] A storage battery 14 is installed on the upper surface of the vehicle board 1. The first motor 6 and the second motor 111 are both electrically connected to the storage battery 14. The storage battery 14 adopts a rechargeable battery, and the first motor 6 and the second motor 111 can be powered by the storage battery 14.

[0033] Working principle: Add fertilizers into the interior of the material bucket 2. When starting to spread fertilizers, start the first motor 6 and the second motor 111. The first motor 6 will drive the two crushing rollers 5 to rotate in opposite directions, and the second motor 111 drives the elbow pipe 9 and the crushing knife 7 to rotate. Then, push the device to move and open the solenoid valve 41. The fertilizers first discharge along the first blanking pipe 4. The fertilizers enter between the two crushing rollers 5 and are crushed. The crushed fertilizers are further crushed by the rotating crushing knife 7 below. Then, the fertilizers enter the elbow pipe 9 along the second blanking pipe 8. Since the elbow pipe 9 rotates at a high speed, the fertilizers can be thrown outwards, thus completing the fertilization operation. This device can crush the fertilizers twice, with good and uniform crushing effects. In addition, this device has a large fertilization range and uniform fertilization.
