Description

Technical fields:

[0001] This utility model belongs to the technical field of agricultural crop processing equipment, specifically referring to a seed feeding machine. Background technology:

[0002] In agricultural production and seed processing, seed screening is a crucial step in ensuring seed quality. Traditional seed screening typically requires manual handling of seeds to the inlet of the screening equipment or reliance on simple conveyor systems. However, existing feeding methods have significant shortcomings: firstly, manual feeding is inefficient, labor-intensive, and difficult to perform continuously in batches, easily affecting the screening accuracy; secondly, due to the smooth surface and high fluidity of seeds, conventional conveyor systems, if tilted at a large angle, can cause seeds to slide downwards without effective obstruction, reducing conveying efficiency and even damaging the seeds. Summary of the Invention:

[0003] The purpose of this invention is to provide a seed feeding machine that uses a valve assembly to quantitatively control the flow rate of seeds falling from the seed hopper onto the feeding conveyor belt mechanism, and uses a lifting baffle to effectively push the seeds upward, ensuring that the seeds can be continuously and in batches fed into the screening device.

[0004] This utility model is implemented as follows:

[0005] A seed feeding machine includes a frame and a feeding conveyor belt mechanism. A seed hopper is mounted on the frame, and a valve assembly capable of adjusting the valve opening is provided at the lower end of the seed hopper. The feeding end of the feeding conveyor belt mechanism is positioned horizontally directly below the lower end of the seed hopper, and the discharging end of the feeding conveyor belt mechanism is inclined upward. The feeding end and the discharging end of the feeding conveyor belt mechanism are connected by a bending part. Several lifting baffles are evenly distributed along the length direction of the conveyor belt and arranged along the width direction of the conveyor belt on the outer surface of the conveyor belt mechanism.

[0006] In the aforementioned seed feeding machine, the valve assembly includes a valve base fixed at the lower port of the seed hopper. The valve base has a valve window corresponding to the structure and position of the lower port of the seed hopper. A sliding valve plate that can completely block and completely open the valve window is horizontally slidably fitted on the valve base. The outer end of the sliding valve plate extends beyond the valve base and is provided with a valve handle.

[0007] In the aforementioned seed feeding machine, the valve base is provided with a locking through hole corresponding to the position of the side wall of the sliding valve plate. A locking screw is threaded onto the locking through hole, and the locking screw can be screwed inward to abut against the side wall of the sliding valve plate.

[0008] In the above-mentioned seed feeding machine, the feeding conveyor belt mechanism includes a mounting frame and a conveyor belt rotatably fitted on the mounting frame. Limiting baffles are symmetrically arranged on the outer surface of the conveyor belt located on both sides of the lifting baffle along its length direction.

[0009] In the aforementioned seed feeding machine, the limiting baffle is composed of several S-shaped limiting baffles continuously distributed along the length of the conveyor belt. The S-shaped limiting baffles, the lifting baffles, and the conveyor belt are an integral injection-molded structure.

[0010] In the aforementioned seed feeding machine, a turning pressure roller is rotatably connected to the mounting frame located on both sides of the bending section. The turning pressure roller has a large ring portion that rolls onto the outer surface of the conveyor belt and a small ring portion that rolls onto the outer end face of the limiting baffle.

[0011] In the aforementioned seed feeding machine, a plurality of support rollers are rotatably connected to the mounting frame located on the reverse rotation side of the conveyor belt, which is distributed along its length and arranged along its width. The support rollers are in rolling contact with the outer wall surface of the limiting baffle.

[0012] In the aforementioned seed feeding machine, a feeding guide plate is mounted on the conveying end of the feeding conveyor belt mechanism along its width direction. The feeding guide plate is located on the reverse rotation side of the conveyor belt, and a scraper brush that can scrape the lifting baffle is provided on the side of the feeding guide plate near the conveyor belt.

[0013] The outstanding advantages of this utility model compared to the prior art are:

[0014] This utility model has a simple structure, reasonable design and high economic benefits. It uses a valve assembly to quantitatively control the flow rate of seeds falling from the seed hopper onto the feeding conveyor belt mechanism, and uses a baffle to effectively push the seeds upward, thereby ensuring that the seeds can be continuously and batch-wise fed into the screening device.

Detailed implementation method:

[0019] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —3:

[0020] A seed feeding machine includes a frame 1 and a feeding conveyor belt mechanism. A seed hopper 2 is mounted on the frame 1. A valve assembly capable of adjusting the valve opening is provided at the lower port of the seed hopper 2. The feeding end of the feeding conveyor belt mechanism is positioned horizontally directly below the lower port of the seed hopper 2. The discharging end of the feeding conveyor belt mechanism is inclined upward. The feeding end and the discharging end of the feeding conveyor belt mechanism are connected by a bending part 3. A plurality of lifting baffles 5 are evenly distributed along the length direction of the outer surface of the conveyor belt 4 of the feeding conveyor belt mechanism, which are arranged along the width direction of the conveyor belt 4.

[0021] This utility model has a simple structure, reasonable design and high economic benefits. It uses a valve assembly to quantitatively control the flow rate of seeds falling from the seed hopper 2 onto the feeding conveyor belt mechanism, and uses a lifting baffle 5 to effectively push the seeds upward, thereby ensuring that the seeds can be continuously and batch-wise fed into the screening device.

[0022] The valve assembly can be a commercially available and common electric valve assembly. In this embodiment, the valve assembly includes a valve base 6 fixed at the lower port of the seed hopper 2. The valve base 6 has a valve window that corresponds to the structure and position of the lower port of the seed hopper 2. A sliding valve plate 7 that can completely block and completely open the valve window is horizontally slidably fitted on the valve base 6. The outer end of the sliding valve plate 7 extends out of the valve base 6 and is provided with a valve handle 8. That is, the sliding valve plate 7 can be manually pulled inward and outward by the valve handle 8 to realize the opening degree of the valve window.

[0023] Furthermore, in order to fix the position of the sliding valve plate 7, a locking through hole corresponding to the position of the side wall of the sliding valve plate 7 is provided on the valve base 6. A locking screw 9 is threadedly connected to the locking through hole. The locking screw 9 can be screwed inward to abut against the side wall of the sliding valve plate 7.

[0024] Furthermore, in order to prevent the seeds from falling off the conveyor belt 4 from the side, the feeding conveyor belt mechanism includes a mounting frame 10 and a conveyor belt 4 rotatably fitted on the mounting frame 10. Limiting baffles are symmetrically provided on the outer surface of the conveyor belt 4 located on both sides of the lifting baffle 5 along its length direction.

[0025] The limiting baffle can be a discontinuously distributed, elongated protrusion structure. However, in this embodiment, in order to adapt to the deformation that occurs when the conveyor belt 4 flips, the limiting baffle is composed of several S-shaped limiting baffles 11 that are continuously distributed along the length of the conveyor belt 4. The S-shaped limiting baffles 11, the lifting baffles 5, and the conveyor belt 4 are an integral injection-molded structure.

[0026] Furthermore, considering that the design of the bend 3 may make it difficult for the conveyor belt 4 to maintain a taut state, turning pressure rollers 12 are rotatably connected to the mounting frames 10 on both sides of the bend 3. The turning pressure rollers 12 have a large ring portion 13 that rolls onto the outer surface of the conveyor belt 4, and a small ring portion 14 that rolls onto the outer end face of the limiting wall. Correspondingly, a plurality of support rollers 15 are rotatably connected to the mounting frame 10 on the reverse rotation side of the conveyor belt 4, which are distributed along its length and arranged along its width. The support rollers 15 roll onto the outer wall surface of the limiting wall.

[0027] Furthermore, in order to allow the seeds between two adjacent lifting baffles 5 to enter the feeding guide plate 16, the feeding guide plate 16 is mounted on the conveying end of the feeding conveyor belt mechanism along its width direction. The feeding guide plate 16 is located on the reverse rotation side of the conveyor belt 4. A scraper brush 17 that can scrape the lifting baffles 5 is provided on the side of the feeding guide plate 16 near the conveyor belt 4. The side of the feeding guide plate 16 away from the conveyor belt 4 is the discharge end for cooperating with the feeding end of the screening device or other equipment.

[0028] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made to the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
