DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 In order to solve the problem that the existing picking belt of the crop picker is subjected to the effects of tension and compression during operation, if the picking belt is too loose or too tight, it is very easy to break, slip, etc., thereby affecting the work efficiency and effect, the following preferred technical solutions are provided:

[0022] A tensioning device for a picking belt of a rice picker comprises a mounting block 1 mounted on the rice picker, two groups of connecting parts are mounted on the outer wall of one end of the mounting block 1, a connecting shaft 2 is mounted between the two groups of connecting parts, an adjusting rod 3 is rotatably connected to the inner cavity of the connecting shaft 2, a picking belt mounting plate 4 is mounted on the end of the adjusting rod 3 away from the connecting shaft 2, a first connecting block 5 and a second connecting block 6 are fixedly connected to the ends of the mounting block 1 opposite to the adjusting rod 3, a reset spring 7 is arranged between the first connecting block 5 and the second connecting block 6, and a control component 8 is arranged on one side of the connecting shaft 2.

[0023] The mounting plate 4 is rotatably connected to the outer wall of the adjusting rod 3 , one end of the reset spring 7 is fixedly connected to the first connecting block 5 , and the other end of the reset spring 7 is fixedly connected to the second connecting block 6 .

[0024] The control assembly 8 includes a control block 81 placed on one side of the connecting member, and a movable groove 82 opened inside the connecting shaft 2. The inner wall of the movable groove 82 is threadedly connected with a control rod 83. One end of the control rod 83 is fixedly connected to the control block 81. The end of the control block 81 close to the connecting member is fixedly connected with an abutment block 84. The abutment block 84 is a component made of rubber material. A fixing groove 85 is opened at the end of the control rod 83 away from the control block 81. A fixing block 86 is fixedly connected to the center of the adjusting rod 3 connected to the connecting shaft 2, and the fixing groove 85 matches the fixing block 86.

[0025] Specifically, when the picking belt becomes too loose or too tight after working for a long time, the adjusting rod 3 can be toggled to make the adjusting rod 3 rotate at an angle through the inner wall of the connecting shaft 2, so as to achieve the purpose of adjusting the position of the picking belt mounting plate 4, thereby adjusting the tension of the picking belt to avoid slipping and breaking. This solves the problem that the picking belt of the existing grain picker will be subjected to the effects of tension and compression during operation. If the picking belt is too loose or too tight, it is very easy to break, slip, etc., thereby affecting the work efficiency and effect. After the adjustment is completed, the control block 81 is rotated to drive the control rod 83 to move on the inner wall of the movable groove 82, so that the control rod 83 presses against the adjusting rod 3, and the abutment block 84 is also close to the outer wall of the connecting piece, so that the adjusting rod 3 can no longer rotate, thereby ensuring the stability after adjustment.

[0026] When the control rod 83 is pressed against the adjusting rod 3, the fixing groove 85 and the fixing block 86 will be engaged with each other, thereby further improving the stability after adjustment. When the picking belt tension needs to be adjusted again, it is only necessary to rotate the control block 81 in the opposite direction to drive the fixing groove 85 and the fixing block 86 away from each other. The adjusting rod 3 can be quickly reset through the reset spring 7 during adjustment, which is convenient for subsequent adjustment and easy to operate.

[0027] To sum up: when the picking belt becomes too loose or too tight after working for a long time, the adjusting rod 3 can be toggled to make the adjusting rod 3 rotate at an angle through the inner wall of the connecting shaft 2, so as to achieve the purpose of adjusting the position of the picking belt mounting plate 4, thereby adjusting the tension of the picking belt to avoid slipping and breaking. After the adjustment is completed, the control block 81 is rotated to drive the control rod 83 to move on the inner wall of the movable groove 82, so that the control rod 83 presses against the adjusting rod 3, and the abutment block 84 also presses against the outer wall of the connecting piece, so that the adjusting rod 3 can no longer rotate. When the control rod 83 presses against the adjusting rod 3, the fixing groove 85 and the fixing block 86 are engaged, thereby further improving the stability after adjustment. When the picking belt tension needs to be adjusted again, the control block 81 only needs to be rotated in the opposite direction to drive the fixing groove 85 and the fixing block 86 away from each other.
