Technical Field

[0001] This utility model relates to the technical field of threshing devices, specifically to a multi-functional threshing machine. Background Technology

[0002] A corn thresher is an agricultural machine specifically designed to separate corn kernels from the corn cob. It greatly improves the efficiency of corn threshing, frees up labor, and is an important post-harvest processing tool in agricultural production.

[0003] A typical household corn thresher includes a thresher body and a feeding port, a threshing drum, a corn kernel outlet, and a corn cob outlet. In use, the operator feeds several ears of corn to be threshed into the feeding port. Under the action of the rotating threshing drum, the corn kernels on the ears are separated from the corn cobs, and then discharged from the corresponding corn cob outlet and corn kernel outlet, respectively.

[0004] During the threshing process, some corn kernels are discharged along with the corn cobs from the corn cob outlet. This results in a mixture of corn cobs and kernels after discharge, which requires workers to separate the mixture. This undoubtedly increases the workload and labor intensity of the workers during the threshing process. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned difficulties and provide a multi-functional thresher that can effectively separate corn cobs from corn kernels.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a multi-functional thresher, including a corn thresher body, a feeding port at one end of the corn thresher body and a corn cob discharge port at the other end, and a collection component on the corn thresher body for receiving the material at the corn cob discharge port, wherein the collection component separates the received corn cob from the corn kernel.

[0007] The collection assembly includes a collection trough that is slidably mounted on the bottom wall of the corn thresher body. The collection trough is equipped with an inclined filter screen and a discharge port on its bottom surface. The end of the collection trough away from the corn cob discharge port is an open structure. A folded flow guiding component is provided in the collection trough above the filter screen. When the flow guiding component is adjusted to an inclined state, it guides the material at the corn cob discharge port into the filter screen. The assembly also includes a fixing component for positioning the collection trough.

[0008] As an improvement, the flow guiding assembly includes fixed seats fixedly installed at both ends of the collection tank, and a flow guiding frame is hinged to both fixed seats. The end of the flow guiding frame near the corn cob outlet is an open structure. A swing rod is hinged to both ends of the flow guiding frame away from the fixed seats. The other end of the two swing rods is hinged to a sliding seat that slides with the collection tank. The collection tank is provided with a positioning assembly for fixing the sliding seat.

[0009] As an improvement, the positioning component includes a mounting base disposed on the collection groove, wherein a positioning pin with a spring-loaded function is slidably disposed within the mounting base, and a pin hole is provided on the sliding base for the positioning pin to extend into.

[0010] As an improvement, the mounting base has a cavity into which the positioning pin passes, and a pressure plate is fixed on the positioning pin. A return spring is sleeved on the positioning pin between the pressure plate and the top wall of the cavity.

[0011] As an improvement, the fixing component includes a bearing seat set at both ends of the collecting trough, and an adjusting screw threaded through the two bearing seats respectively. The upper and lower ends of the adjusting screw are respectively provided with support plates, and the corn thresher body is fixed with an abutment seat that is abutted by the upper support plate.

[0012] As an improvement, the corn thresher body is provided with a support frame, and two support frames are provided with a sliding seat. A sliding groove that cooperates with the sliding seat is fixed on the bottom surface of the collection trough, and the collection trough is also provided with a traveling wheel that cooperates with the ground.

[0013] As an improvement, when the guide frame is adjusted to an inclined state, it is set to correspond to the corn cob discharge port, and the area of ​​the guide frame is larger than the area of ​​the corn cob discharge port.

[0014] As an improvement, the lower end of the filter extends to the opening structure of the collection tank.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. With the help of the collection and guiding components, the mixture discharged from the corn cob outlet can be guided to the filter screen by the guiding component. The mixture flows on the inclined filter screen by its own weight. During the flow of the mixture, the corn kernels inside will pass through the filter screen and fall below the filter screen, and then be discharged to the outside through the discharge port. The corn cobs will flow to the bottom of the filter screen and be discharged to the outside through the opening structure of the collection tank. This can effectively separate the mixed corn cobs from the corn kernels. This not only reduces the number of steps in the threshing operation, but also reduces the labor intensity of the workers.

[0017] 2. With the sliding collection trough and folding guide frame in place, when the device is not in use, the guide frame can be adjusted to a horizontal position first, and then the collection trough can be slid under the corn thresher body. This not only facilitates the transfer of the device, but also reduces the storage area of ​​the device. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 4As shown, a multi-functional thresher includes a corn thresher body 1. The corn thresher body 1 has a feeding port 11 at one end, a corn cob discharge port 12 at the other end, a corn kernel discharge port 17 on the side, and a threshing drum that rotates inside to thresh the corn cobs. The above features belong to the prior art. The corn thresher body 1 is provided with a collection component 2 for receiving the material at the corn cob discharge port 12. The collection component 2 separates the received corn cobs from the corn kernels.

[0028] To facilitate the relocation of this device and reduce its footprint when not in use, the aforementioned collection component 2 is designed to be retractable. The collection component 2 includes a collection trough 21 slidably mounted on the bottom wall of the corn thresher body 1. An inclined filter screen 22 is installed within the collection trough 21, and a discharge port 23 is provided on the bottom surface. The discharge port 23 corresponds to the filter screen 22, and its area is larger than that of the filter screen 22. The end of the collection trough 21 furthest from the corn cob outlet 12 is open. The lower end of the filter screen 22 extends to… At the opening of the collection trough 21, a foldable flow guide component 3 is provided inside the collection trough 21 above the filter screen 22. When the flow guide component 3 is adjusted to an inclined state, it can guide the material at the corn cob outlet 12 onto the filter screen 22. The foldable design of the flow guide component 3 allows it to be in a horizontal state when the collection trough 21 slides below the corn thresher body 1, thus preventing interference with the corn thresher body 1. To ensure the stability of the collection trough 21 after sliding, a fixing component 4 for positioning the collection trough 21 is also included.

[0029] With the above structure, the corn thresher body 1 is first placed in the designated position, then the positioning of the collection trough 21 is released, and the collection trough 21 is moved to the outside of the corn thresher body 1. Then, the flow guiding component 3 is adjusted to an inclined state. During the corn cob threshing process, the corn cobs and mixed corn kernels discharged from the corn cob discharge port 12 will be blocked and guided by the flow guiding component 3, causing them to fall onto the filter screen 22. The weight of the corn cobs and corn kernels will cause them to flow downward on the inclined filter screen 22. During the flow, the corn kernels inside will pass through the filter screen 22 and fall below it, and then be discharged to the outside through the discharge port 23. The corn cobs will flow to the bottom of the filter screen 22 and be discharged to the outside through the opening structure of the collection trough 21. This can effectively separate the discharged corn cobs and corn kernels, which not only reduces the number of threshing steps but also reduces the labor intensity of the workers.

[0030] Combined with appendix Figure 2 and attached Figure 3As shown, the flow guiding assembly 3 includes fixed seats 31 fixedly disposed at both ends of the collection tank 21. A flow guiding frame 32 is hinged to both fixed seats 31. The end of the flow guiding frame 32 near the corn cob outlet 12 is open. A swing rod 33 is hinged to each end of the flow guiding frame 32 away from the fixed seats 31. The other ends of the two swing rods 33 are respectively hinged to a sliding seat 34 that slides with the collection tank 21. When the flow guiding frame 32 is adjusted to an inclined state, it is positioned corresponding to the corn cob outlet 12. By adjusting the inclination state of the flow guiding frame 32, the discharged corn cobs can be guided. The guide frame 32 effectively blocks and guides the corn cobs and mixed corn kernels onto the filter screen 22. Since the corn cobs and mixed corn kernels have a certain impact force when they are discharged during the threshing process, the area of ​​the guide frame 32 is larger than the area of ​​the corn cob discharge port 12. This avoids the overflow of corn cobs and mixed corn kernels when they are discharged. The collection tank 21 is equipped with a positioning component 5 for fixing the sliding seat 34. When the guide frame 32 is adjusted to an inclined state, the positioning component 5 positions the sliding seat 34, thereby enabling the positioning operation of the adjusted guide frame 32.

[0031] Combined with appendix Figure 1 and attached Figure 5 As shown, the positioning component 5 includes a mounting base 51 disposed on the collection groove 21. A positioning pin 52 with a spring-loaded function is slidably disposed in the mounting base 51. A pin hole is provided on the sliding seat 34 for the positioning pin 52 to extend into. With the cooperation of the positioning pin 52 and the pin hole, the sliding seat 34 can be fixed on the collection groove 21.

[0032] The mounting base 51 has a cavity 53 into which the positioning pin 52 passes. A pressure plate 54 is fixed on the positioning pin 52. A return spring 55 is sleeved on the positioning pin 52 between the pressure plate 54 and the top wall of the cavity 53. A handle 56 is also provided on the top surface of the positioning pin 52.

[0033] Combined with appendix Figure 1 and attached Figure 6As shown, the fixing component 4 includes a bearing seat 41 at both ends of the collecting trough 21. An adjusting screw 42 is threaded through each of the two bearing seats 41. Support plates 43 are rotatably mounted on the upper and lower ends of the adjusting screw 42. An abutment seat 44, which is abutted against by the upper support plate 43, is fixed on the corn thresher body 1. A turntable 45 is also mounted on the adjusting screw 42. When the collecting trough 21 is extended, rotating the turntable 45 causes the adjusting screw 42 to rotate. Under the action of the threaded force, the adjusting screw 42 moves downward, simultaneously causing the lower support plate 43 to move downward, so that the bottom surface of the support plate 43 is tightly abutted against the ground, thereby effectively positioning the extended collecting trough 21. When the collecting trough 21 is retracted, rotating the adjusting screw 42 in the opposite direction causes the upper support plate 43 to move upward, so that the top surface of the support plate 43 is tightly abutted against the bottom surface of the abutment seat 44, thereby effectively positioning the retracted collecting trough 21.

[0034] Combined with appendix Figure 1 and attached Figure 7 As shown, the corn thresher body 1 is provided with a support frame 13, and two support frames 13 are provided with a sliding seat 14. The bottom surface of the collection trough 21 is fixed with a sliding groove 15 that cooperates with the sliding seat 14. In order to ensure the stability of the collection trough 21 during use after it is extended, two walking wheels 16 that cooperate with the ground are provided at both ends of the bottom surface of the collection trough 21. The walking wheels 16 can effectively support the extended collection trough 21.

[0035] In the specific implementation of this utility model, in the initial state, the guide frame 32 is in a horizontal state, and the collection trough 21 is retracted to the bottom wall of the corn thresher body 1. In use, the corn thresher body 1 is moved to a designated position, and then the positioning of the collection trough 21 is released. The collection trough 21 is moved to the outside of the corn thresher body 1 by external force and positioned there. Then the guide frame 32 is adjusted to an inclined state, and then the positioning component 5 is used to position the adjusted guide frame 32.

[0036] During the corn threshing process, the corn cobs and mixed corn kernels discharged from the corn cob outlet 12 are blocked by the inclined guide frame 32. Then, under their own weight, the corn cobs and mixed corn kernels fall onto the filter screen 22 and slide downwards on the inclined filter screen 22. During the sliding process, the corn cobs and mixed corn kernels are effectively separated. This not only reduces the number of steps in the threshing operation, but also reduces the labor intensity of the workers, thereby improving the practicality of the device.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
