Description

Technical Field

[0001] This utility model relates to the field of fertilization equipment technology, specifically to a fertilization device for improving the aggregate structure of sandy alluvial soil. Background Technology

[0002] Sandy alluvial soil is a common soil type in North China and Northwest my country. It is characterized by coarse particles, large pores, and weak water and fertilizer retention capacity. The soil aggregate structure is easily dispersed by rainfall and irrigation, resulting in rapid fertilizer loss and low crop absorption efficiency. In order to improve the aggregate structure of alluvial soil, organic fertilizer (such as well-rotted sheep manure) and inorganic amendment (such as attapulgite powder) can be combined and mixed by a stirring motor to produce fertilizer that can improve the aggregate structure of alluvial soil.

[0003] In related technologies, a search revealed a fertilizer spreader with a mixing mechanism, such as patent number CN217825954U. This patent discloses a material bin with four sets of rotatable wheels mounted on the bottom. A handle with anti-slip sleeves is fixedly mounted on the top front side of the bin. A shaft is placed at the bottom of the bin and is fixedly connected to the bin via a wheel frame. Both ends of the shaft are rotatably connected to the wheels via bearings. A rotating rod passes through the center of the bin for mixing and blending fertilizer.

[0004] However, when using the testing equipment to prepare fertilizer, because the inside of its hopper is connected to the discharge pipe, some organic fertilizer will fall directly into the discharge pipe when raw materials are added, causing the discharge pipe to become blocked. In addition, organic fertilizer (such as decomposed sheep manure) is also prone to sticking together when being added, which increases the probability of blocking the discharge pipe. To solve the above problems, a fertilizer application device that improves the granular structure of sandy alluvial soil is proposed to solve the above problems. Utility Model Content

[0005] In view of this, the present invention provides a fertilization device for improving the granular structure of sandy and humid soil. The present invention uses a cutting mechanism to prevent organic fertilizer from sticking together. Attapulgite powder is fed into the inorganic hopper, allowing the decomposed sheep manure and attapulgite powder to enter the mixing drum. The driving motor drives the mixing arm on the mixing assembly to rotate and mix the fertilizer. After mixing, the plate valve is opened to allow the fertilizer to enter the feeding hopper. Then, the fertilizer is discharged into the planting channels on both sides through the inclined discharge pipe, thereby preventing organic fertilizer from clogging the discharge pipe and reducing the equipment maintenance rate.

[0006] To solve the above-mentioned technical problems, this utility model provides a fertilization device for improving the aggregate structure of sandy alluvial soil, including a material box set on the bearing surface of a mobile cart, a mixing drum fixedly set inside the material box, a mixing component set along its axial direction inside the mixing drum, a drive motor rotatably set on the top of the mixing component, a guide hopper connected to the bottom of the mixing drum, a plate valve fixedly set at the discharge end of the guide hopper, a batching hopper connected to the bottom of the plate valve, a discharge pipe symmetrically set at the discharge end of the batching hopper, a drive motor fixedly set on the top of the material box, an organic hopper set adjacent to the drive motor, a cutting mechanism set on the organic hopper, and an inorganic hopper set adjacent to the organic hopper.

[0007] The mixing assembly includes a mixing shaft that is rotatably connected to a drive motor. The mixing shaft is used to fix a connecting ring, so that when the drive motor drives the mixing shaft to rotate, the connecting ring can drive the mixing arm fixed thereto to rotate. Several connecting rings are provided on the surface of the mixing shaft. The connecting rings are used to connect the mixing arm to the mixing shaft. Each connecting ring is provided with a mixing arm on its surface. The mixing arm is used to mix the fertilizer in the mixing drum.

[0008] Each mixing arm is equipped with a scraper at one end near the inner wall of the mixing drum. The scraper is used to scrape off the sticky fertilizer on the inner wall of the mixing drum.

[0009] A coupling is provided on the output shaft of the drive motor. The coupling is used to connect the output shaft of the drive motor to the stirring shaft, so that the drive motor can drive the stirring shaft to rotate. The coupling is embedded in the middle of the top arm of the material box. A motor bracket is provided at the bottom of the drive motor to fix and support the drive motor.

[0010] The mixing hopper is a cone-shaped hopper with a partition inside. The partition is used to divide the mixing hopper into two halves, each half of which is connected to a discharge pipe. This allows the moving trolley to simultaneously apply the mixed fertilizer to the planting lanes on both sides while it is moving. The partition is set along the axial direction of the plate valve, and the movable end of the plate valve extends out of the hopper.

[0011] The organic hopper includes an inclined feeding hopper that connects the mixing drum to the feeding trough. The discharge end of the feeding hopper is connected to the top of the mixing drum. The top of the feeding hopper is equipped with a feeding trough for adding organic fertilizer.

[0012] The cutting mechanism includes a pair of cutting rollers with a crossbeam set inside the hopper. The cutting rollers drive the cutting teeth to rotate. Each cutting roller has multiple cutting teeth on its surface. The cutting teeth are used to cut the sticky parts of the organic fertilizer to prevent the organic fertilizer from sticking together when it is fed, which would affect subsequent mixing. The cutting teeth on both sides are staggered and matched. Each cutting roller has a roller shaft inside. The roller shaft is used to rotate and connect to the cutting motor. The cutting motor drives the roller shaft to rotate, which in turn drives the cutting roller to rotate the cutting teeth. The cutting motor is set at one end of the roller shaft, and a bearing seat is set at the other end of the roller shaft to fix the other end of the roller shaft and prevent it from shaking during operation.

[0013] The inorganic hopper includes an inclined feed pipe for flowing powdered inorganic modifier. The feed pipe has a feed cylinder at its inlet end for dispensing the inorganic modifier. A support frame is provided at the bottom of the feed cylinder for fixing and supporting the feed cylinder. The support frame is fixedly connected to the outer wall of the hopper.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The cutting mechanism prevents organic fertilizer from sticking together. Attapulgite powder is fed into the inorganic hopper, allowing the decomposed sheep manure and attapulgite powder to enter the mixing drum. The drive motor rotates the mixing arm on the mixing assembly to mix the fertilizer. After mixing, the plate valve is opened to allow the fertilizer to enter the feeding hopper. Then, the fertilizer is discharged into the planting channels on both sides through the inclined discharge pipe, thereby preventing organic fertilizer from clogging the discharge pipe and reducing the equipment maintenance rate.

[0015] 2. The partition is used to separate the feeding hopper, dividing it into two halves. Each half is connected to a discharge pipe. The electric valve is located inside the hopper, which allows the moving trolley to simultaneously apply the prepared fertilizer to the planting lanes on both sides while it is moving.

[0016] 3. The stirring shaft is used to fix the connecting ring, so that when the drive motor drives the stirring shaft to rotate, the connecting ring can drive the stirring arm fixed to it to rotate. The connecting ring is used to connect the stirring arm to the stirring shaft. The stirring arm is used to stir the fertilizer in the mixing drum, and the scraper is used to scrape off the sticky fertilizer on the inner wall of the mixing drum. Attached Figure Description
