Description

Technical Field

[0001] This utility model relates to the field of agricultural seeding equipment technology, specifically to a seeder feed box that is easy to clean. Background Technology

[0002] A seeder is a planting machine that uses crop seeds as the object of sowing. Among them, the seeder hopper is a storage component in the seeder used to store the crop seeds to be planted. The conventional seeder hopper structure is as follows: it includes a hopper body, with a seed feeding port at the top and a feeding port at the bottom. The problems with this structure of the seeder hopper are: (1) The hopper body is generally made of metal, so the remaining crop seeds inside the hopper cannot be observed in real time during the sowing operation. If the observation is not timely when the machine is stopped on time, it will lead to missed sowing. At this time, it is necessary to add crop seeds into the hopper body and replant the empty sowing area. It is difficult to ensure that the empty sowing area is fully replanted, which poses a risk of missing seedlings later and seriously affects the sowing efficiency; (2) There is no drainage component at the bottom of the hopper body. When it is necessary to change to different types of crop seeds, or when the remaining crop seeds inside the hopper body are taken out after sowing, it is necessary to remove the hopper body from the seeder body, which is cumbersome. To this end, this utility model proposes a seeder hopper body that is easy to clean in order to solve the above technical problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a seeder hopper that is easy to clean. By setting an observation window component on the side wall of the seeder hopper, operators can easily observe the remaining amount of crop seeds inside the seeder hopper in real time, thereby allowing for timely replenishment of crop seeds and effectively avoiding empty sowing, while also improving sowing efficiency. By setting a discharge and emptying component at the bottom of the seeder hopper, when sowing is completed or when it is necessary to change to a different variety of crop seeds, the discharge and emptying component can be opened to empty the remaining crop seeds inside the seeder hopper. Compared to disassembling the entire seeder hopper from the seeder, this significantly reduces the difficulty of emptying the crop seeds. The overall structure is ingeniously and reasonably designed, with high feasibility for preparation and implementation and strong practicality.

[0004] To achieve the above objectives, the technical solution of this utility model is to design a seeder feed box that is easy to clean, including a seed box, wherein the upper port of the seed box is detachably covered with a tarpaulin, the bottom is provided with a discharge port, the side wall of the seed box is provided with an observation window assembly, and the bottom of the seed box is also provided with a discharge and emptying assembly.

[0005] This utility model discloses an easy-to-clean seeder hopper. An observation window component is installed on the side wall of the seeder hopper, allowing workers to observe the remaining amount of crop seeds inside in real time. This enables timely replenishment of crop seeds, effectively preventing empty sowing and improving sowing efficiency. A discharge and emptying component is installed at the bottom of the seeder hopper. When sowing is completed or when changing to a different crop variety, the remaining crop seeds can be emptied by opening the discharge and emptying component. Compared to disassembling the entire seeder hopper from the seeder, this significantly reduces the difficulty of emptying the crop seeds. The overall structure is ingeniously and rationally designed, with high feasibility for preparation and implementation, and strong practicality.

[0006] A preferred technical solution is that the lower end of the seeding box is a tapered structure that gradually tapers from top to bottom, the discharge port is located at the bottom of the tapered structure, and the unloading and emptying component is located at the lower end of the side wall of the tapered structure. The tapered structure at the lower end of the seeding box allows the crop seeds stored inside the seeding box to continuously collect at the discharge port during the seeding process, ensuring effective seed feeding. When emptying the seeding box, as the crop seeds continuously flow out from the unloading and emptying component, the small amount of residual crop seeds inside the seeding box will also continuously collect at the tapered part and be discharged from the unloading and emptying component, helping to improve the emptying efficiency of the seeding box.

[0007] A further preferred technical solution includes a discharge and venting assembly comprising a discharge pipe, a locking nut, an end cap, and a sealing gasket. The discharge pipe has an external thread structure on its outer circumferential side, and a hexagonal eaves at the center of its outer circumferential side. A vent is located at the lower end of the conical sidewall. The upper end of the discharge pipe extends through the vent into the seed box. The locking nut is screwed onto the upper end of the discharge pipe. The hexagonal eaves abut against the outer surface of the conical sidewall. The end cap is screwed onto the lower end of the discharge pipe, and the sealing gasket is placed at the bottom of the end cap. The discharge and venting assembly has a clever and reasonable structural design, and its fixing and installation on the conical sidewall is simple, ensuring the smooth fabrication and implementation of the seeder's feed box of this invention.

[0008] A further preferred technical solution is that viewing windows are provided on both the front and rear side walls of the seeding box, and viewing window plates are installed inside the viewing windows. The viewing windows and viewing window plates constitute the observation window assembly. The observation window assembly has a simple structural design, high feasibility in preparation and implementation, and strong practicality.

[0009] A further preferred technical solution includes a detachable guide plate assembly on the lower side and a screen assembly on the upper side installed inside the feeding port. The screen assembly filters the crop seeds, effectively preventing large-diameter seed particles from agglomerating and clogging the feeding port or causing uneven seeding. The guide plate assembly guides and diverts the seeds falling from the screen assembly, preventing seed adhesion and clogging of the feeding port due to moisture or other reasons, ensuring smooth seed flow during feeding.

[0010] A further preferred technical solution is that the guide plate assembly includes a guide ramp and two side plates. The two side plates are fixedly mounted on the left and right edges of the guide ramp, and are located diagonally above the guide ramp. The upper ends of the two side plates are fixedly connected together by a connecting rod. Both the upper edge of the guide ramp and the upper edges of the two side plates have a second flange extending diagonally upwards and outwards. The ends of the two side plates opposite to the guide ramp also have a first flange bending in opposite directions. When the guide plate assembly is inserted into the discharge port, the second flange overlaps the upper edge of the discharge port, and the first flange abuts against the front or rear inner wall surface of the discharge port. The detachable installation method of the guide plate assembly inside the discharge port is simple, allowing the guide plate assembly to be manually removed when emptying the seed box, thereby emptying all the seeds trapped in the gap between the guide plate assembly and the discharge port.

[0011] A further preferred technical solution includes a screen assembly comprising a screen and a frame, wherein the screen is embedded and fixed inside the frame; at least one pair of U-shaped brackets with openings facing upwards and into the seed box are fixed on the inner walls of the left and right sides of the conical structure, respectively; each of the upper ends of the two arms of the U-shaped bracket is provided with a V-shaped groove, and the left and right sides of the frame are respectively engaged with the V-shaped grooves at the upper ends of the two arms of the corresponding U-shaped brackets. The detachable installation method of the screen assembly inside the discharge port is simple, so that the screen assembly can be manually removed when emptying the seed box, thereby emptying all the seeds clamped in the gap between the screen assembly and the discharge port.

[0012] A further preferred technical solution is that a plurality of sleeves are fixedly provided on one of the front edge or rear edge of the tarpaulin at intervals along its left and right length directions, and the other of the front edge or rear edge of the tarpaulin has a skirt extending downwards. The skirt is pressed and fixedly installed on the upper end of the front side wall or the upper end of the rear side wall of the seeding box by a pressure strip assembly.

[0013] A shaft tube is inserted inside several of the aforementioned sleeves. Both ends of the shaft tube extend to the outside of the sleeve and are detachably fitted with limiting components to restrict its axial movement inside the sleeve. Several downwardly extending rings are spaced apart along the length of the shaft tube. Several hanging components are fixed on the front or rear outer wall of the seed box. The box also includes several elastic pull strips. The upper end of each elastic pull strip has an insertion section. Several hanging holes are spaced apart along the longitudinal length of the elastic pull strip. The insertion section is inserted into the rings. The elastic pull strip is elastically tightened and hooked onto the corresponding hanging components through the hanging holes. The installation of the tarpaulin at the upper end of the seed box is simple. The pressure strip assembly ensures the stability of the fixed installation of either the front or rear end of the tarpaulin on the upper end of the corresponding front or rear side wall of the seed box. The other end of the tarpaulin is detachably connected to the front or rear side wall of the seed box through a shaft tube, sleeve, elastic strip, and hanging assembly. This ensures the ease of operation when that end of the tarpaulin is lifted, thereby ensuring the ease and efficiency of adding crop seeds into the seed box.

[0014] A further preferred technical solution is that the pressing strip assembly includes a pressing strip and several pads with mounting holes. Corresponding mounting holes are provided on the upper end of the front or rear side wall of the seed box, the skirt, and the pressing strip. The skirt is attached to the outer side of the upper end of the front or rear side wall of the seed box, the pressing strip is pressed onto the skirt, and the upper end of the front or rear side wall of the seed box, the skirt, and the pressing strip are fixedly connected together by bolt assemblies that pass through the corresponding mounting holes. The pads are connected to the bolts of the bolt assemblies and are attached to the outer side of the pressing strip.

[0015] The limiting component includes a limiting sleeve. Both the limiting sleeve and the end of the shaft tube have mounting holes with an axial center line. The limiting sleeve is sleeved and installed on the end of the shaft tube, and the two are locked together by bolt assemblies that pass through the corresponding mounting holes. The shaft tube is also sleeved with several sleeves two, which are correspondingly embedded in the gap between two adjacent sleeves one. The ring body is fixed on the sleeve two.

[0016] The mounting assembly includes a screw and a nut. The screw passes through the front or rear side wall of the seed box from the inside out, and the nut is screwed onto the outer end of the screw. The outer circumferential side of the nut has an annular groove, and the inner wall of the annular groove is designed with an arc-shaped transition surface. The ingenious and reasonable structural design of the pressure strip assembly, the limiting assembly, and the mounting assembly ensures the smooth manufacture and implementation of the seeder feed box of this utility model.

[0017] A further preferred technical solution is that handles are fixedly provided on the outer surfaces of the front and rear side walls of the seeding box. The handles help improve the ease of operation when the seeding box is lifted or transported.

[0018] The advantages and beneficial effects of this utility model are as follows:

[0019] 1. This utility model provides an easy-to-clean seeder hopper. By installing an observation window component on the side wall of the seeder hopper, operators can easily observe the remaining amount of crop seeds inside the seeder hopper in real time, allowing for timely replenishment of crop seeds and effectively preventing empty sowing, while also improving sowing efficiency. By installing a discharge and emptying component at the bottom of the seeder hopper, when sowing is completed or when changing to a different variety of crop seeds, the discharge and emptying component can be opened to empty the remaining crop seeds inside the seeder hopper. Compared to disassembling the entire seeder hopper from the seeder, this significantly reduces the difficulty of emptying the crop seeds. The overall structural design is ingenious and reasonable, with high feasibility for preparation and implementation, and strong practicality.

[0020] 2. The lower end of the seeding box is designed as a tapered structure that gradually tapers from top to bottom. The discharge port is located at the bottom of the tapered structure, and the unloading and emptying component is located at the lower end of the side wall of the tapered structure. The tapered structure at the lower end of the seeding box allows the crop seeds stored inside to continuously collect at the discharge port during the seeding process, ensuring effective seed feeding. When emptying the seeding box, as the crop seeds continuously flow out from the unloading and emptying component, the small amount of residual crop seeds inside the seeding box also continuously collects at the tapered part and is discharged from the unloading and emptying component, helping to improve the emptying efficiency of the seeding box.

[0021] 3. The feed inlet is detachably equipped with a guide plate assembly on the lower side and a screen assembly on the upper side. The screen assembly filters the crop seeds, effectively preventing large-sized seeds from agglomerating and clogging the feed inlet or causing uneven seeding. The guide plate assembly guides and diverts the seeds falling from the screen assembly, preventing seeds from sticking together and clogging the feed inlet due to moisture or other reasons, ensuring smooth seed flow during feeding.

[0022] 4. The detachable installation method of the guide plate assembly or screen assembly inside the discharge port is simple, so that the guide plate assembly or screen assembly can be disassembled by hand when emptying the seed box, thereby emptying all the seeds clamped in the gap between the guide plate assembly and the discharge port, and the seeds clamped in the gap between the screen assembly and the discharge port.

[0023] 5. The installation of the tarpaulin at the upper end of the seed box is simple. The pressure strip assembly ensures the stability of the fixed installation of either the front or rear end of the tarpaulin on the upper end of the corresponding front or rear side wall of the seed box. The other end of the tarpaulin is detachably connected to the front or rear side wall of the seed box through the shaft tube, sleeve, elastic strip and hanging assembly, ensuring the ease of operation when lifting that end of the tarpaulin, thereby ensuring the ease and efficiency of adding crop seeds into the seed box.

Then, the end of the tarpaulin 2 with the shaft tube 8 is re-fixed to the upper end of the front or rear side wall of the seeding box 1.

[0056] (ii) During the sowing operation, the remaining amount of crop seeds inside the sowing box 1 can be observed in real time through the observation window component. When the remaining amount of crop seeds inside the sowing box 1 is not much, crop seeds can be added to the sowing box 1 in accordance with step (i).

[0057] (III) Principle of Emptying Crop Seeds

[0058] When the crop seeds inside the seeding box 1 need to be emptied after the sowing operation is completed, unscrew the end cap 5-3 from the lower end of the discharge pipe 5-1. You can also refer to step (1) to lift the tarpaulin 2, remove the screen assembly 4 and the guide plate assembly 3, clean the crop seeds, and then reinstall the two inside the discharge port 1-3.

[0059] (iv) Principle of Crop Seed Replacement

[0060] When it is necessary to replace the crop seeds inside the seeding box 1, unscrew the end cap 5-3 from the lower end of the discharge pipe 5-1. Alternatively, refer to step (1) to lift the tarpaulin 2, remove the screen assembly 4 and the guide plate assembly 3, clean the crop seeds, and then reinstall them inside the discharge port 1-3. After the crop seeds inside the seeding box 1 are cleaned, reinstall the end cap 5-3 at the lower end of the discharge pipe 5-1. Then, add a certain amount of target crop seeds into the seeding box 1. Finally, re-fix the end of the tarpaulin 2 with the shaft tube 8 to the upper end of the front or rear side wall of the seeding box 1.

[0061] This utility model discloses an easy-to-clean seeder hopper. An observation window component is installed on the side wall of the seeder hopper, allowing workers to observe the remaining amount of crop seeds inside in real time. This enables timely replenishment of crop seeds, effectively preventing empty sowing and improving sowing efficiency. A discharge and emptying component is installed at the bottom of the seeder hopper. When sowing is completed or when changing to a different crop variety, the remaining crop seeds can be emptied by opening the discharge and emptying component. Compared to disassembling the entire seeder hopper from the seeder, this significantly reduces the difficulty of emptying the crop seeds. The overall structure is ingeniously and rationally designed, with high feasibility for preparation and implementation, and strong practicality.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
