Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization machinery technology, specifically to a small-sized fertilizer spreader with adjustable fertilization rate for dryland planting. Background Technology

[0002] When cultivating crops (such as corn), fertilization is required before tilling. There are two common fertilization methods: one is manual spreading of fertilizer, but this is labor-intensive, inefficient, and prone to uneven spreading; the other is using fertilizer spreading machines, which can replace manual labor and reduce labor intensity. However, fertilizer spreading machines usually apply fertilizer in furrows or holes, where fertilizer is poured vertically or obliquely into the furrow or hole through a guide pipe. This usually requires additional steps such as furrowing and covering with soil. Therefore, they cannot achieve the goal of evenly distributing fertilizer on the soil surface, which urgently needs improvement. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a small, simple, reasonably designed, and easy-to-use fertilizer spreader for dryland planting with adjustable fertilizer application rate. It achieves the purpose of spreading fertilizer by driving the fertilizer to rotate horizontally, so that the fertilizer covers the soil surface, and the fertilizer application rate can be adjusted according to the soil needs.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a frame, with wheels on all four sides of the bottom of the frame, a handle on the upper left side of the frame, a fertilizer cylinder on the upper side of the frame, and a discharge rack at the bottom of the fertilizer cylinder, the discharge rack being inserted into and fixed within the frame; it also includes:

[0005] The rotating frame is screwed onto and fixed to the bottom of the discharge frame via a bearing, and a tapered guide frame is provided at the inner end of the rotating frame, and a discharge hole is provided at the bottom of the rotating frame.

[0006] A rotating gear, which is sleeved and fixed to the upper end of the rotating frame;

[0007] The spraying motor is fixedly mounted on the frame by a motor bracket and is located on the right side of the discharge frame. After the output shaft of the spraying motor passes through the frame, a transmission gear is sleeved and fixed thereon, and the transmission gear meshes with the rotating gear.

[0008] The measuring table is movably installed at the bottom of the material discharge rack, and the outer ring wall of the measuring table is arranged in a conical inclination from top to bottom and from the inside to the outside.

[0009] A quantity control component, wherein the quantity control component is disposed inside the discharge rack;

[0010] Through the above technical solution design, fertilizer flows from the discharge rack into the rotating rack, and is guided by the conical guide rack so that all the fertilizer is placed on the inner bottom surface of the rotating rack and flows downward from the discharge hole. The spreading motor is started, so that the transmission gear drives the rotating gear to rotate, so that the rotating rack rotates during the discharge process, and the fertilizer is spread on the soil. During this process, the amount of fertilizer discharged from the discharge rack is controlled by the metering component, and the spreading amount is changed.

[0011] As a further improvement of this utility model, the measurement control component includes:

[0012] Fertilizer guide frame, wherein the fertilizer guide frame is disposed inside the discharge frame, and the bottom of the left and right sides of the fertilizer guide frame is connected to the inner ring wall of the discharge frame;

[0013] The operating frame is located inside the discharge frame and inside the fertilizer guide frame. The front and rear outer walls of the operating frame are respectively connected to the front and rear inner walls of the fertilizer guide frame.

[0014] The driving tooth block is slidably inserted into a through slot at the bottom of the operating frame. A connecting strip is fixedly installed at the bottom of the driving tooth block, and the bottom end of the connecting strip is connected to the control table.

[0015] The guide motor is fixedly mounted on the inner rear wall of the operating frame via a motor bracket, and a drive gear is sleeved and fixed on the output shaft of the guide motor. The drive gear is located on the front side of the drive gear block.

[0016] The driven gear is meshed on the left side of the driving gear, and a driven shaft is inserted and fixed inside the driven gear. The front and rear ends of the driven shaft are respectively screwed onto the inner wall of the corresponding operating frame through bearings.

[0017] The guide gears are two in number and are respectively meshed on the left and right sides of the drive gear block; and the guide gears are respectively sleeved and fixed on the output shaft and driven shaft of the guide motor.

[0018] The above technical solution design starts the guide motor, causing the drive gear to rotate and mesh with the driven gear to rotate. Then, the two guide gears simultaneously drive the drive gear block, which moves the control table through the connecting strip, changing the distance between the control table and the bottom inner ring wall of the discharge rack.

[0019] As a further improvement of this utility model, a movable block is provided on the rear side of the drive tooth block, and the movable block is slidably disposed with the rear inner wall of the operating frame; a support rod is inserted through the movable block, and the bottom end of the support rod is fixedly disposed on the inner bottom surface of the operating frame.

[0020] Through the above technical solution design, the moving tooth block is guided by the sliding of the moving block when it moves, and the moving block is guided by sliding with the inner rear wall of the operating frame and sliding with the support rod.

[0021] As a further improvement of this utility model, the outer end of the fertilizer cylinder is fitted with a circumferential gear through a bearing, and an agitator is provided on the upper side of the circumferential gear. The horizontal end of the agitator is located on the upper side of the fertilizer cylinder, and the other end of the agitator passes through the inside of the fertilizer cylinder. The agitator is located on the upper side of the fertilizer guide. A rotating motor is fixedly installed on the upper side of the frame through a motor bracket, and a rotating gear is provided on the upper output shaft of the rotating motor. The rotating gear meshes with the circumferential gear.

[0022] Through the above technical solution design, the rotating motor drives the rotating gear to rotate, which in turn meshes with the circumferential gear to rotate, thereby causing the agitator to stir inside the fertilizer cylinder and prevent the fertilizer from clumping.

[0023] As a further improvement of this utility model, the handle is fitted with an anti-slip sleeve, and the anti-slip sleeve is provided with anti-slip particles.

[0024] The above technical solution design improves hand comfort during prolonged use.

[0025] As a further improvement of this utility model, a power supply box is provided on the frame, and a switch is provided on the handle. The switch is connected to the power supply box, and the spraying motor, the guide motor, and the rotating motor are respectively connected to the switch and the power supply box.
