Description

Technical Field

[0001] This utility model patent relates to the field of potato technology, and in particular to a potato seed cutter discharge sorting device. Background Technology

[0002] In the seed potato production process, when using a seed cutter, potatoes need to be cut into individual pieces weighing 35-70g, ensuring that each piece has at least two eyes. Existing potato machines have issues with producing pieces that are either too large or too small. Larger pieces can be manually cut a second time, while smaller pieces have no further processing value. Therefore, it is necessary to sort the potatoes at the output stage, removing those that are significantly too small and do not meet the planting standards. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of sorting out excessively small potato tubers that do not meet planting requirements during the output of potato seed cutters, and to propose a potato seed cutter output sorting device. By adjusting the spacing of the grading rollers, this device can effectively sort out excessively small potato tubers.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A potato seed cutter discharge sorting device is designed, comprising a frame, sorting roller, tension wheel, connecting plate, sorting roller shaft, cam, tension spring, spring, bearing seat, channel steel, connecting rod, sprocket, adjusting rod sleeve, and adjusting rod. The entire device is installed after the potato seed cutter's discharge port and performs sorting operations after seed cutting. The actuators of the potato seed cutter discharge sorting device, excluding the transmission system, are symmetrical left and right; therefore, the following description only focuses on the single-sided adjusting mechanism, while the right-side mechanism is analogous to the left.

[0005] As a preferred embodiment of this utility model, the frame is made of square steel, angle steel and steel plate by welding and hinge, and the remaining parts are installed in various parts of the sorting device frame to form the potato seed cutter discharge sorting device.

[0006] As a preferred embodiment of this utility model, the sorting roller is made of rubber and has uniformly raised ridges on its surface, which can increase friction without damaging the seed potatoes.

[0007] As a preferred embodiment of this utility model, the upper end of the channel steel is hinged to the frame, the distance between adjacent hinge points is equal, eight bearing seats are respectively installed on the side of the channel steel, eight sorting roller shafts pass through the eight bearing seats and are connected to the channel steel, and eight sorting rollers are respectively sleeved on the sorting roller shafts.

[0008] As a preferred embodiment of this utility model, the connecting rod passes through the transverse opening of the channel steel, and a spring is sleeved on the connecting rod between adjacent channel steels. The end of the connecting rod is welded to the channel steel, and the beginning of the connecting rod is threaded and fixed to the channel steel with a nut.

[0009] In a preferred embodiment of this invention, the adjusting rod is connected to the channel steel at its outermost end by a rotatable pin, and the adjusting rod sleeve is a hollow structure with internal threads. The external threads of the adjusting rod engage to allow for telescopic adjustment. The middle section of the adjusting rod is connected to the frame by a nut, thus securing the adjusting rod.

[0010] In a preferred embodiment of this invention, the sprocket, connecting plate, tension spring, tension wheel, and cam constitute the power transmission components of the device. The connecting plate and frame, the tension wheel and connecting plate, the sprocket and frame, and the cam and frame are all connected by nuts. The tension wheel, tension spring, connecting plate, and cam provide tension for the entire chain drive.

[0011] By adopting the above technical solution, the potato seed cutter discharge sorting device provided by this utility model has the following advantages compared with the prior art:

[0012] The aforementioned potato seed cutter discharge sorting device has a simple structure and is easy to operate. The power input to the transmission system drives the sorting rollers to rotate. By rotating the adjusting rod, the spring can be released or compressed to adjust the spacing of the sorting rollers, thereby realizing the grading and cleaning of potato tubers of different sizes.

[0013] Figure 1 This is a schematic diagram (axonometric view) of the structure of this utility model.

[0014] Figure 2 This is a schematic diagram (isometric view) of the transmission system.

[0015] Figure 3 This is the right view of the present invention.

[0016] The numbers in the diagram are explained as follows: 1. Frame; 2. Sorting roller; 3. Tensioning wheel; 4. Connecting plate; 5. Sorting roller shaft; 6. Cam; 7. Tension spring; 8. Spring; 9. Bearing seat; 10. Channel steel; 11. Connecting rod; 12. Sprocket; 13. Adjusting rod sleeve; 14. Adjusting rod. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1 As shown, the potato seed cutter's discharge sorting device is symmetrical from left to right except for the power transmission part. Therefore, the following description only refers to the left side of the device with reference to the attached drawings, while the right side is the same as the left side.

[0019] like Figure 1 As shown, the frame 1 is composed of square steel, angle steel and steel plate by welding and hinge. The remaining parts are installed in various parts of the sorting device frame, together forming the potato seed cutter discharge sorting device.

[0020] like Figure 1 , Figure 2 As shown, there are gaps between the 8 grading rollers 2, which are used to sort and remove overly small tubers that do not meet the planting standards.

[0021] like Figure 1 , Figure 2 As shown, the adjusting rod sleeve 13 has a horizontal hole and is connected to the channel steel at the very end by a rotatable pin. The adjusting rod 14 passes through a nut welded to the frame. The adjusting rod sleeve 13 and the adjusting rod 14 each have internal and external threads. By rotating the adjusting rod 14, the adjusting rod 14 can be extended or shortened, thereby driving the adjusting rod sleeve 13 forward and backward.

[0022] like Figure 2 , Figure 3 As shown, eight channel steels 10 are sequentially hinged on the frame 1, and all can rotate around the hinge point. Each of the eight channel steels 10 has a bearing seat 9 installed on its left side. Eight sorting roller shafts 5 are installed on the eight channel steels 10 through the bearing seats 9. Eight sorting rollers 2 are respectively sleeved on the sorting roller shafts 5 and move with the channel steels 10.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, each of the eight channel steels 10 has a transverse hole. The connecting rod 11 passes through the transverse hole and is welded to the end of the channel steel 10. The first end is fixed to the channel steel 10 by a nut. A spring 8 is sleeved on the connecting rod 11 between adjacent channel steels 10. The compression and release of the spring 8 can cause the channel steel 10 to rotate around the hinge point with the frame 1.

[0024] like Figure 2 , Figure 3 As shown, sprockets 12 of different sizes are installed on the sorting roller shaft 5 and the frame 1, forming the power transmission part of the device. One end of the connecting plate 4 is hinged to the frame 1 and can rotate around the hinge point. The other two ends are connected to the tension spring 8 and the tension wheel 3, respectively. The tension spring 8 is connected to the frame. The extension and retraction of the tension spring 8 can cause the connecting plate 4 to rotate around the hinge point, thereby driving the tension wheel 3 to rotate with the connecting plate 4. The cam 6 is hinged to the frame and can rotate around the hinge point. By adjusting the position of the cam 6, the chain link can be lifted.

[0025] The working principle of this utility model is explained below: the sprocket drives the sorting roller to rotate, causing the potato tubers to be continuously transported backward. Unqualified potato tubers are discharged through the gap between adjacent grading rollers. Manually rotating the adjusting rod releases or compresses the spring on the connecting rod, causing the channel steel to rotate around the hinge point. As the channel steel rotates, the bearing seat connected to the end drives the sorting roller shaft and the sorting roller to move, continuously increasing or decreasing their spacing, thereby adjusting the spacing between the grading rollers. This achieves the sorting and removal of excessively small potato tubers that do not meet planting requirements.
