Description

Technical Field

[0001] This utility model relates to the field of single-plant threshing machine technology, specifically to a simple receiving device for removing impurities from a single-plant threshing machine for legume crops. Background Technology

[0002] In the current process of threshing soybeans, mung beans, and other legumes using single-plant threshers, there is no dedicated seed collection device at the seed outlet. Seeds are typically collected in containers such as basins or directly in seed mesh bags. The collected seeds often contain larger impurities such as pod shells and broken plant stems, requiring manual sieving to remove these impurities before bagging. Alternatively, seeds can be collected directly in mesh bags, and impurities are removed one by one after all single-plant samples have been threshed, a time-consuming and labor-intensive process. Furthermore, using basins to collect seeds easily causes them to splash out, resulting in contamination and seed loss, further reducing efficiency. Therefore, it is necessary to provide a simple receiving device for removing impurities from single-plant threshers used for legume crops to solve these problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a simple receiving device for removing impurities from single-plant threshing machines of legumes. This device solves the problems of impurities in seeds during the process of putting them into bags after threshing, the inconvenience of not having a special collection device for threshed seeds, and the time-consuming and labor-intensive process of seeds splashing when receiving seeds in containers. It reduces the need for secondary cleaning during the single-plant threshing of legumes, saves time, is convenient, and improves work efficiency.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A simple receiving device for removing impurities from a single legume threshing machine includes a cylinder with an open top. A hanging plate is provided at the inner edge of the opening at the top of the cylinder. A pull-out port is provided at the lower end of the side wall of the cylinder. A pull-out box is provided inside the pull-out port. A collection cylinder is provided inside the cylinder above the pull-out port.

[0006] A suspension plate is horizontally suspended below the suspension plate by a suspension component. A gap is left between the suspension plate and the inner wall of the cylinder. The inner diameter of the suspension plate is smaller than the inner diameter of the suspension plate.

[0007] A support plate is provided above the suspension plate. The outer diameter of the support plate is smaller than the inner diameter of the suspension plate but larger than the inner diameter of the suspension plate. The inner diameter of the support plate is smaller than the inner diameter of the suspension plate. A screen with an inner diameter smaller than the inner diameter of the suspension plate is installed below the support plate. At least three limiting rods are vertically fixed evenly around the outside of the screen below the support plate.

[0008] The support plate is connected to the receiving hopper via an installation column, and the receiving hopper is connected to the discharge port of the single-plant thresher.

[0009] In one embodiment of this utility model, the cylinder is cylindrical, and the hanging plate, suspension plate and support plate are all annular; the collecting cylinder is inverted conical, with its top fixed to the inner wall of the cylinder and a discharge port provided at the middle of its bottom.

[0010] In one embodiment of this utility model, the lifting component and the limiting groove are arranged in a ring with no fewer than three of them; the lifting component is a steel wire rope, a spring, or a column whose upper and lower ends are respectively hinged to the hanging plate and the suspension plate.

[0011] In one embodiment of this utility model, both the limiting groove and the limiting rod are square, and the length of the limiting rod is more than three times the depth of the limiting groove.

[0012] In one embodiment of this utility model, the screen is a cylindrical shape with an open top, and its side walls and bottom are evenly provided with screen holes.

[0013] In one embodiment of this utility model, the receiving hopper is a hollow shell with openings at both the inner and outer ends, and is inclined with the outer side higher than the inner side; the outer ends of the left and right side walls of the receiving hopper are provided with connecting holes, and the receiving hopper and the discharge port of the single-plant thresher are connected by bolt assemblies, so as to transmit the vibration of the single-plant thresher to the screen.

[0014] In one embodiment of this utility model, the receiving hopper is a deep-extending receiving hopper, which includes a first receiving hopper and a second receiving hopper nested together. The inner end of the first receiving hopper is fixedly connected to the mounting column. The left and right side walls of the outer end of the first receiving hopper are provided with a plurality of connecting holes along the length direction. The left and right side walls of the inner end of the second receiving hopper are provided with connecting holes. The connecting holes on the first receiving hopper and the second receiving hopper are connected by bolt assemblies. The left and right side walls of the outer end of the second receiving hopper are provided with connecting holes and bolt assemblies.

[0015] In one embodiment of this utility model, the pull-out box is a box body with an opening at the top, and its outer end face is an arc-shaped surface that matches the cylindrical surface of the cylinder. A handle is provided on the arc-shaped surface.

[0016] The beneficial effects of adopting the above technical solution are as follows:

[0017] The simple receiving device for removing impurities from single-plant legume threshers provided by this utility model has an ingenious structural design. It solves the problems of impurities in seeds during the process of putting them into bags after threshing by single-plant threshers, which require secondary cleaning; the inconvenience of not having a special collection device for threshed seeds; and the time-consuming and labor-intensive process of seed splashing when receiving seeds with a container. It reduces the need for secondary cleaning during the single-plant threshing of legumes, saves time, is convenient, and improves work efficiency.

[0018] The receiving hopper is a hollow shell open at both ends, while the discharge port of the single-plant thresher is an inclined U-shaped plate. When the receiving hopper is connected to the discharge port of the single-plant thresher, it is placed over the discharge port to prevent seeds from splashing. Furthermore, the length of the receiving hopper is adjustable, allowing for adaptive adjustment of the cylinder position to the height of the discharge port, facilitating the installation and debugging of the receiving device.

[0019] After threshing, the seeds enter the sieve and fall through the sieve holes into the collection cylinder, and then through the discharge port into the pull-out box. This process removes impurities, avoids the need for further cleaning, and collects the seeds.

[0020] The lower end of the receiving hopper is fixedly connected to the support plate via a mounting column, and the upper end is fixedly connected to the discharge port of the single-plant thresher. This allows the vibration of the single-plant thresher during operation to be transmitted to the screen, agitating the seeds and impurities within the screen, accelerating seed collection, preventing accumulation, and avoiding the problem of seeds being trapped among impurities and unable to fall. A suspension plate is installed to support the weight of the support plate and screen, keeping the support plate horizontal and at a relatively stable height. Furthermore, the suspension plate is connected to the hanging plate via a hanging component, which reduces the transmission of vibration to the cylinder, increasing the vibration amplitude of the support plate and making the cylinder more stable.

Detailed Implementation

[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0030] like Figures 1-7 The present invention relates to a simple receiving device for removing impurities from a single legume threshing machine, comprising a cylinder 1 with an opening at the top, a hanging plate 2 provided at the inner edge of the opening at the top of the cylinder 1, a pull-out port 8 provided at the lower end of the side wall of the cylinder 1, a pull-out box 9 provided inside the pull-out port 8, and a collecting cylinder 6 provided above the pull-out port 8 inside the cylinder 1.

[0031] A suspension plate 4 is horizontally suspended below the suspension plate 2 by a suspension member 3. A gap is left between the suspension plate 4 and the inner wall of the cylinder 1. The inner diameter of the suspension plate 4 is smaller than the inner diameter of the suspension plate 2, and the outer diameter of the suspension plate 4 is larger than the inner diameter of the suspension plate 2.

[0032] A support plate 12 is provided above the suspension plate 4. The outer diameter of the support plate 12 is smaller than the inner diameter of the suspension plate 2 and larger than the inner diameter of the suspension plate 4. The inner diameter of the support plate 12 is smaller than the inner diameter of the suspension plate 4. A limiting rod 13 corresponding to the limiting groove 5 is vertically fixed below the support plate 12. A screen 11 with an inner diameter smaller than the inner diameter of the suspension plate 4 is installed below the support plate 12. At least three limiting rods 13 are vertically fixed evenly on the outer circumference of the screen 11 below the support plate 12, so that the limiting rods 13 are in direct contact with the suspension plate 4 to prevent the suspension plate 4 from bumping and damaging the screen 11.

[0033] The support plate 12 is connected to the receiving hopper via the mounting column 14, and the receiving hopper is connected to the discharge port of the single-plant thresher.

[0034] In this embodiment, the cylinder 1 is cylindrical, and the hanging plate 2, the suspension plate 4 and the support plate 12 are all annular; the collecting cylinder 6 is inverted conical, with its top fixed to the inner wall of the cylinder 1 and a discharge port 7 provided at the middle of its bottom.

[0035] like Figure 1 , Figures 4-6 As shown, at least three lifting components 3 and limiting grooves 5 are evenly arranged in a ring. The lifting component 3 is a steel wire rope, a spring, or a column whose upper and lower ends are respectively hinged to the lifting plate 2 and the suspension plate 4 via universal joints. The lifting component 3 is preferably a steel wire rope or a spring, because steel wire ropes and springs can reduce the transmission of vibrations from all directions to the cylinder 1, while the column has high rigidity but relatively weak vibration isolation effect. When selecting a spring, the height of the cylinder 1 should be reasonably set so that the interaction force between the suspension plate 4 and the support plate 12 is greater than the sum of the weights of the support plate 12, the screen 11, and the mounting column 14. This avoids excessive downward force on the mounting column 14 and the receiving hopper, preventing damage to the weaker parts of the device due to excessive stress.

[0036] like Figure 4 and Figure 5 As shown, the inner wall of the suspension plate 4 can be provided with a limiting groove 5 corresponding to the limiting rod 13 along the vertical direction, so that the limiting rod 13 is located in the limiting groove 5. In this embodiment, both the limiting groove 5 and the limiting rod 13 are square, and the length of the limiting rod 13 is more than three times the depth of the limiting groove 5. It should be noted that when the limiting rod 13 is located in the limiting groove 5, sufficient gap must be maintained between the screen 11 and the suspension plate 4 to prevent the suspension plate 4 from damaging the screen 11 during vibration.

[0037] The screen 11 is a cylindrical shape with an open top, and its side walls and bottom are evenly provided with screen holes.

[0038] The receiving hopper is a hollow shell with openings at both the inner and outer ends, and is inclined with the outer end higher than the inner end. Connecting holes are provided at the outer ends of the left and right side walls of the receiving hopper. Bolt assemblies 17 connect the receiving hopper to the discharge port of the single-plant thresher, transmitting the vibration of the single-plant thresher to the screen 11. The receiving hopper is a hollow shell with openings at both ends, while the discharge port of the single-plant thresher is an inclined U-shaped plate. When the receiving hopper is connected to the discharge port of the single-plant thresher, it is fitted over the discharge port to prevent seeds from splashing.

[0039] like Figure 7 As shown, as a further optimization, the receiving hopper is a deep-extending receiving hopper, which includes a first receiving hopper 15 and a second receiving hopper 16 nested together. The inner end of the first receiving hopper 15 is fixedly connected to the mounting column 14. The left and right side walls of the outer end of the first receiving hopper 15 are provided with multiple connecting holes along the length direction. The left and right side walls of the inner end of the second receiving hopper 16 are provided with connecting holes. The connecting holes on the first receiving hopper 15 and the second receiving hopper 16 are connected by bolt assemblies 17. The left and right side walls of the outer end of the second receiving hopper 16 are provided with connecting holes and bolt assemblies 17. The length of the receiving hopper is adjustable, and the position of the cylinder 1 can be adaptively adjusted according to the height of the discharge port, which facilitates the installation and debugging of the receiving device.

[0040] The pull-out box 9 is a box with an opening at the top, and its outer end face is an arc-shaped surface that matches the cylindrical surface of the cylinder 1. A handle 10 is provided on the arc-shaped surface.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
