DETAILED DESCRIPTION

[0025] The technical scheme of the utility model will be described clearly and completely in combination with embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] It is explained that the orientation concepts of "left", "right", "up", "down", "front", "back", "inner" and "outer" in the following scheme are relative directions, which will not be listed one by one.

[0027] A crop harvesting and threshing device with vertical cutting knives, referring to Figures 1-6The device comprises two opposite side plates 1. A threshing assembly 2 is arranged between the two side plates 1. The threshing assembly 2 comprises a threshing part 10 which is hollow, upper side and front side open. A discharge port 3 is arranged at the rear side of the threshing part 10. A plastic baffle 12 is arranged at the upper side of the threshing part 10. A threshing roller 11 is rotatably arranged in the threshing part 10. A clamping and conveying assembly 5 and a support part 14 for supporting the clamping and conveying assembly 5 are arranged at the front side opening of the threshing part 10. An installation part 14 is arranged at the front side of the support part 14. A cross-cutting knife assembly 6 is installed at the installation part 14. The cross-cutting knife assembly comprises a moving rod. The moving rod 15 is movably arranged between the installation part 14 and the clamping and conveying assembly 5. A plurality of cross-cutting knives 16 are arranged on the moving rod 15. A vertical cutting knife assembly 7 is arranged on one of the side plates 1. The vertical cutting knife assembly 7 comprises a slide rail 8 which is fixedly arranged on the side plate 1. Two vertical cutting knives 9 are slidably arranged on the slide rail 8. The two vertical cutting knives 9 always move in opposite directions.

[0028] When the device is used for harvesting and threshing rape, the cross-cutting knife assembly 6 is responsible for cutting the rape. The cut rape is sent into the threshing part 10 by the clamping and conveying assembly 5 for threshing. After the threshing is completed, the threshed rape is sent out from the discharge port 3. If the rape beside the side plate 1 is clamped and conveyed by the clamping and conveying assembly 5, when the root of the rape contacts the vertical cutting knife assembly 7, the opposite movement of the vertical cutting knife 9 in the vertical cutting knife assembly 7 can cut the rape, so that the root of the rape is not pulled out and sent into the threshing part 10.

[0029] The side plate 1 provided with the vertical cutting knife assembly 7 is internally hollow, and an input rod 17 is rotatably arranged on the side plate 1. An input wheel 18 is arranged at one end of the side plate 1 outside. For those skilled in the art, the input wheel 18 can be a gear, a belt wheel, a chain wheel, etc., as long as the output end of the driving source used to drive the operation of the device can be connected with the output wheel. For those skilled in the art, the driving source can be a motor, a diesel engine, a gasoline engine, etc. Since it is prior art, it will not be described in detail here. The input rod 17 is fixedly sleeved with a first chain wheel 19 and a first belt wheel 20 at one end inside the side plate 1. A threshing rod 21 connected with the threshing roller 11 and a second chain wheel 22 are rotatably arranged inside the side plate 1. The threshing rod 21 is fixedly sleeved with a third chain wheel 23 and a fourth chain wheel. The first chain wheel 19 is connected with the third chain wheel 23 through a first chain 24. The second chain wheel 22 is connected with the fourth chain wheel through a second chain 25. A gear box 26 is arranged on the support part 13. The second chain wheel 22 is connected with the input end of the gear box 26. The output end of the gear box 26 is connected with the input end of the clamping and conveying assembly 5. For those skilled in the art, the clamping and conveying assembly 5 can be the clamping and conveying part in the existing harvesting and threshing device, and the gear box 26 replaces the motor that drives the existing clamping and conveying part to rotate. Since they are prior art, they will not be described in detail here. A first tensioning wheel 27 for tensioning the first chain 24 and a second tensioning wheel 28 for tensioning the second chain 25 are also rotatably arranged inside the side plate 1.

[0030] A swing box 29 is arranged inside the side plate 1. The swing box 29 is provided with a second belt wheel 31 at the input end. The first belt wheel 20 is connected with the second belt wheel 31 through a belt 30. The swing box 29 is provided with a swing seat 32 at the output end. The swing seat 32 is connected with the moving rod 15. The swing seat 32 is fixedly connected with a swing arm 33 at the end away from the swing box 29. A base 34 connected with the sliding rail 8 is fixedly arranged inside the side plate 1. A transmission rod 35 is rotatably arranged on the base 34. One end of the transmission rod 35 is connected with the end of the swing arm 33, and the other end is connected with the center of a connecting block 36. The connecting block 36 is hingedly connected with connecting rods 37 at both ends. The two connecting rods 37 are respectively hingedly connected with the two vertical cutting knives 9 at both ends.

[0031] When power is input from the input wheel 18, the moving rod 15 is mainly driven to move reciprocatingly and transversely (the moving rod 15 will also move upwardly to some extent due to the output of the swing box 29), thereby completing the transverse cutting work of the rape; the threshing roller 11 is driven to rotate, thereby completing the threshing work; the clamping and conveying assembly 5 is driven to work, thereby completing the clamping and conveying operation of the rape; and the two vertical cutting knives 9 are driven to move reciprocatingly and oppositely, thereby cutting the rape rolled in from the side.

[0032] The above merely describes preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein, through the above description or related technical or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the claims of the present application.
