Description

Technical Field

[0001] This utility model relates to the technical field of agricultural fertilization, specifically a fertilizer box for a seeder. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a certain type or type of crop are often named after the crop, such as grain row seeders, corn hill seeders, cotton seeders, and pasture spreaders. To improve seed survival rate, fertilizer tanks are usually installed on the seeder to fertilize the sowing area simultaneously with sowing.

[0003] In response to this, CN216905890U proposes a fertilizer box for a seeder. The fertilizer box and seeder provided by this utility model have a fixed feed inlet, which can realize fixed-point feeding. The fertilizer is crushed by a crushing and filtering device, which helps to reduce the volume of fertilizer and increase the fluidity of fertilizer. At the same time, the fertilizer is dispersed into the box by a uniform distribution device, eliminating the need for manual distribution. The feeding efficiency is high and it is conducive to realizing automated and mechanized feeding.

[0004] However, the above-mentioned technical solutions and existing fertilizer boxes for seeders have a buffer function at the fertilizer dispensing port. When dispensing, because the fertilizer accumulates in the fertilizer box, once the dispensing port is opened, the fertilizer will rush out all at once. In this process, not only may too much fertilizer be dispensed, causing the seeds to overgrow and fail to survive, but also a large amount of fertilizer may rush out from the dispensing port, causing the fertilizer to squeeze each other and block the dispensing port, making it impossible to complete the fertilization operation and affecting the fertilization efficiency. In view of this, this design proposes a fertilizer box for seeders. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer box for a seeder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model proposes a fertilizer box for a seeder, including a box body and a feeding mechanism and a scraping mechanism both installed inside the box body, and the inner side of the box body is an inclined surface in the shape of a cone;

[0007] The feeding mechanism includes a feeding trough installed at the bottom of the box. A through groove is opened at the bottom of the inner wall of the box, and the inner wall of the through groove is connected to the inner wall of the feeding trough. A blade roller is rotatably connected to the upper edge of the through groove on the inner wall of the box, and the blade tip of the blade roller is infinitely close to the lower edge of both sides of the inner wall of the feeding trough. An arc-shaped cover is installed on the upper edge of the blade roller on the inner wall of the box. An inclined plate is fixedly installed at the lower edge of the inner wall of the feeding trough. A feeding cylinder is installed at one edge of the bottom of the feeding trough. A discharge hole is opened at one edge of the inclined plate, and the inner wall of the discharge hole is connected to the inner wall of the feeding cylinder.

[0008] In one example, a motor is installed at the lower edge of one side of the outer wall of the housing, and one end of the blade roller passes through the outer wall of one side of the housing and is fixedly connected to the output end of the motor.

[0009] In one example, the scraping mechanism includes a through hole located at the middle of one side of the inner wall of the box, with a sleeve inserted through the inner wall of the through hole, and a positioning shaft fixedly located at the middle of the other side of the inner wall of the box.

[0010] In one example, the sleeve slides on the outer wall of the positioning shaft, and scraper blades are fixed on both sides of one end of the sleeve. The outer walls of one side of the two scraper blades are in contact with the two sides of the inner wall of the box, and a handle is connected to one end of the sleeve through the outer wall of one side of the box.

[0011] In one example, a protective cover is inserted through the top of the box, and a feed funnel is installed on one side of the top of the protective cover, with the inner wall of the feed funnel passing through the inner wall of the protective cover and communicating with the inner wall of the box.

[0012] In one example, a control switch is fixedly installed on one side of the housing, and the motor is electrically connected to an external power source through the control switch.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a feeding mechanism, fertilizer is put into a box with an inclined inner wall, so that the fertilizer automatically slides into the channel. The blade roller rotates, and the upper blade rotates, causing the fertilizer falling into it to tumble onto the inclined plate in the feeding trough. During this process, the blade roller tumbles the falling fertilizer and brings it into the feeding trough, effectively controlling the flow of fertilizer and preventing large-scale outflow that would cause the fertilizer at both ends of the fertilizer box to squeeze and block each other, and prevent large-scale outflow that would cause some seeds to be over-fertilized and unable to survive.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a fertilizer box for a seeder, including a box body 1 and a feeding mechanism 2 and a scraping mechanism 3, both installed inside the box body 1, and the inner side of the box body 1 is a conical inclined surface.

[0022] The feeding mechanism 2 includes a feeding trough 201 installed at the bottom of the housing 1. A through groove 202 is provided at the bottom of the inner wall of the housing 1, and the inner wall of the through groove 202 communicates with the inner wall of the feeding trough 201. A blade roller 203 is rotatably connected to the inner wall of the housing 1 at the upper edge of the through groove 202, and the blade ends of the blade roller 203 are infinitely close to the lower edges of both sides of the inner wall of the feeding trough 201. An arc-shaped cover 204 is installed on the inner wall of the housing 1 at the upper edge of the blade roller 203. An inclined plate 205 is fixedly provided at the lower edge of the inner wall of the feeding trough 201. A feeding cylinder 206 is installed at one edge of the bottom of the feeding trough 201. A discharge hole 207 is provided at the edge, and the inner wall of the discharge hole 207 is connected to the inner wall of the feeding cylinder 206. An arc-shaped cover 204 is installed above the blade roller 203. The arc-shaped cover 204 is fixed inside the box 1, so that the fertilizer poured in from the top will not directly hit the blade roller 203 and cause it to be damaged. At the same time, under the protection of the arc-shaped cover 204, the blade roller 203 rotates more smoothly. The fertilizer enters the through groove 202 from the side of the arc-shaped cover 204, and falls evenly onto the inclined plate 205 under the drive of the smoothly rotating blade roller 203, so that it enters the feeding cylinder 206 from the discharge hole 207 and is discharged in an orderly manner.

[0023] A motor 208 is installed at the lower edge of one side of the outer wall of the housing 1, and one end of the blade roller 203 passes through the outer wall of one side of the housing 1 and is fixedly connected to the output end of the motor 208.

[0024] In use, the container 1 holds fertilizer, and the inner wall of the container 1 is inclined, causing the fertilizer to slide into the through groove 202 inside the container 1. During the sliding process, when the fertilizer falls into the through groove 202, the motor 208 drives the blade roller 203 to rotate. The blades at the upper end of the roller continuously sweep the sliding fertilizer and guide it orderly into the lower part of the inner wall of the through groove 202, where it rolls onto the inclined plate 205 in the through groove 202. When it rolls to the edge of the inclined plate 205, it is... The fertilizer is discharged from the discharge hole 207 through the feed cylinder 206. During this process, the blades of the blade roller 203 continuously tumble the fertilizer, allowing it to enter the channel 202 in an orderly manner. This prevents a large amount of fertilizer from accumulating in the channel and causing blockages. At the same time, the amount of fertilizer discharged is controlled, preventing a large amount of fertilizer from being discharged from the discharge end at the same time. This solves the problems in actual use, such as the fertilizer box discharge end being uncontrollable, resulting in a large amount of fertilizer flowing out and causing blockages at the discharge end, affecting fertilization efficiency, and excessive fertilizer discharge at one time causing excessive seed fertilization.

[0025] Furthermore, the scraping mechanism 3 includes a through hole 301 located in the middle of one side of the inner wall of the housing 1. A sleeve 302 is inserted through the inner wall of the through hole 301. A positioning shaft 303 is fixedly provided in the middle of the other side of the inner wall of the housing 1. The positioning shaft 303 is fixed to one side of the inner wall of the housing 1, and one end of it extends to the edge of the inner wall of the through hole 301, so that when the sleeve 302 is inserted in the through hole 301, it always slides on the positioning shaft 303.

[0026] Furthermore, the sleeve 302 slides on the outer wall of the positioning shaft 303. Scraper blades 304 are fixed on both sides of one end of the sleeve 302, and the outer walls of one side of the two scraper blades 304 respectively contact the two sides of the inner wall of the box 1. One end of the sleeve 302 passes through the outer wall of one side of the box 1 and is connected to a handle 305. After the fertilizer is applied, some fertilizer may stick to the inner wall of the box 1. By pulling the handle 305, the sleeve 302 slides on the positioning shaft 303, which causes the scraper blades 304 to scrape the sticky fertilizer on the inner wall of the box 1 and roll it on the inclined surface into the through groove 202, ensuring that the fertilizer can be fully discharged.

[0027] Furthermore, a protective cover 4 is inserted and connected to the top of the box 1. A feeding funnel 5 is installed on one side of the top of the protective cover 4, and the inner wall of the feeding funnel 5 passes through the inner wall of the protective cover 4 and communicates with the inner wall of the box 1. During use, the protective cover 4 is placed on the top of the box 1, and fertilizer is fed in through the feeding funnel 5 at its top.
