[0039] In the embodiment, the front end vibrating piece 210 is mounted on the base 100 and can vibrate relative to the base 100, and the after end vibrating piece 220 is also arranged on the base 100 and can vibrate relative to the base 100, and they are respectively located on the two sides of the longitudinal direction of the base 100. The rotary frame 230 is rotatably mounted on the after end vibrating piece 220, and the screen bed 300 is arranged on the rotary frame 230. After the rotary frame 230 is rotated by a certain inclination angle relative to the front end vibrating piece 210 and the after end vibrating piece 220, the two ends of the longitudinal direction of the rotary frame 230 are respectively supported by the front end vibrating piece 210 and the after end vibrating piece 220, which can avoid the reduction of rigidity caused by the too long length of the longitudinal direction of the rotary frame 230.
[0040] When it is necessary to adjust the transverse inclination of the screen bed 300, the rotary frame 230 is rotated to change the relative angle of the rotary frame 230 with the front end vibrating piece 210 and the after end vibrating piece 220, so as to make the transverse inclination of the vibration seat 200 become larger or smaller. Through the design of the front end vibrating piece 210, the after end vibrating piece 220 and the rotary frame 230, the problem of difficult adjustment of the transverse inclination of the screen bed 300 in the related art is effectively solved. First of all, without disassembling the excitation rod and other complex operations, the adjustment of the transverse inclination of the screen bed 300 can be realized only by the rotation of the rotary frame 230, which is simple and convenient to operate and improves the work efficiency. Secondly, the damage and precision error caused by disassembling and reinstalling the excitation rod and other components are avoided, which ensures the stability and reliability of the equipment. Furthermore, the user can adjust in real time according to the actual screening situation, which enhances the adaptability and flexibility of the equipment and can better meet the screening needs of different seeds.
[0041] Further, one end of the after end vibrating piece 220 has a circular hole 221 and a plurality of adjustment holes 205, the other end of the front end vibrating piece 210 has a plurality of adjustment holes 205, and the two ends of the rotary frame 230 have a plurality of fixing holes 231, and the rotary frame 230 rotates around the circular hole 221.
[0042] In this embodiment, the rotating frame 230 rotates around the circular hole 221 on the rear end vibrator 220, and the rotating frame 230 maintains the same angle change with the front end vibrator 210 and the rear end vibrator 220. After the rotating frame 230 is adjusted to rotate, it can be fixed through the fixed hole 231 and the adjustment hole 205. The circular hole 221 and the plurality of adjustment holes 205 provide multiple choices for the rotation and angle fixation of the rotating frame 230, and increase the accuracy and flexibility of the transverse inclination adjustment of the screening bed 300. Secondly, the different positions of the adjustment hole 205 can meet the different inclination requirements, and adapt to a wider working scene and screening requirements.
[0043] Further, the circular hole 221 is located at the lowest end of the rear end vibrator 220.
[0044] In this embodiment, the rotating axis of the rotating frame 230 is located at the transverse low end of the rear end vibrator 220, and the transverse inclination of the vibrating seat 200 is adjusted from the lowest end of the entire vibrating seat 200. On the one hand, it can prevent the rotating frame 230 from colliding with the base 100 due to operation errors, and on the other hand, the rotation is more stable and balanced, which is conducive to accurately controlling the amplitude and angle of adjustment. Finally, this layout method saves more space compared with other methods, making the entire device more compact.
[0045] Further, the cam sleeve 500 is provided with two cam sleeves 500, and the two cam sleeves 500 are respectively arranged at both ends of the driving shaft; one end of the first transmission rod 600 is rotatably arranged on one cam sleeve 500, and the other end is arranged on the front end vibrator 210; one end of the second transmission rod 700 is rotatably arranged on the other cam sleeve 500, and the other end is arranged on the rear end vibrator 220; and the elastic support 800 is arranged at both ends of the base 100 and the vibrating seat 200 respectively.

The elastic support 800 not only provides stable elastic support in this process, but also plays a guiding role in the vibration direction of the vibrating seat 200. The cooperation of the cam sleeve 500 and the transmission rod ensures efficient transmission and accurate control of vibration, and improves the stability and consistency of vibration.
[0047] Further, the adjustment hole 205 is a circular arc, and the fixed hole 231 is a circular hole.
[0048] In this embodiment, when the horizontal inclination angle of the vibrating seat 200 needs to be adjusted, the rotating frame 230 is rotated around the circular hole 221 of the rear end vibrating member 220. Since the adjusting hole 205 is a circular arc hole, during the rotation of the rotating frame 230, each fixing hole 231 can always coincide with an adjusting hole 205. When the angle adjustment is completed, a bolt is passed through a fixing hole 231 and an adjusting hole 205, and then a nut is used to fix the rotating frame 230 on the front end vibrating member 210 and the rear end vibrating member 220. In actual use, the operator only needs to tighten or loosen the nut connecting the rotating frame 230 with the front end vibrating member 210 and the rear end vibrating member 220, and then rotate the rotating frame 230 around the circular hole 221, so as to realize the angle adjustment of the vibrating seat 200.

[0050] In this embodiment, the arc center of the adjusting hole 205 is located on the axis of the circular hole 221, which can better adapt to the rotation of the rotating frame 230, so that the fixing hole 231 on the rotating frame 230 can always be aligned with the adjusting hole 205.
[0051] Further, the rotating frame 230 is fixed on the front end vibrating member 210 and the rear end vibrating member 220 by the fastener passing through the adjusting hole 205 and the fixing hole 231.
[0052] In this embodiment, the fixing mode of the fastener passing through the hole is simple and direct, convenient to operate, and can quickly realize the fixation of the rotating frame 230. Secondly, it ensures that the rotating frame 230 can be firmly maintained at the required angle after adjustment, and the angle will not change due to vibration or other external forces, thereby ensuring the stability of the horizontal inclination angle of the screening bed 300 during operation. Furthermore, this fixing mode is easy to check and maintain, and if the angle needs to be adjusted again, the fastener can be loosened for operation.
[0053] Further, the elastic support 800 includes a plurality of spring sheets 810, one end of each spring sheet 810 is arranged on the base 100, and the other end is arranged on the front end vibrating member 210 and the rear end vibrating member 220 respectively, and the spring sheet 810 is used to support the front end vibrating member 210; a plurality of compression springs 820, one end of each compression spring 820 is arranged on the base 100, and the other end is arranged on the front end vibrating member 210 and the rear end vibrating member 220 respectively, and the spring sheet 810 and the compression spring 820 are both inclined relative to the base 100, and the inclination directions of the compression spring 820 and the spring sheet 810 are opposite.
[0054] In the embodiment, the combination of the spring sheet 810 and the compression spring 820 provides stronger and more stable elastic support, which can effectively cope with the impact force generated by vibration and improve the stability of the vibration seat 200. Secondly, the spring sheet 810 also has a guiding effect, so that the vibration seat 200 can move in a direction perpendicular to the elastic sheet 810.
[0055] Further, the front end vibration piece 210, the rear end vibration piece 220 and the rotating frame 230 all have a plurality of process holes.
[0056] In the embodiment, the process holes can be used to reduce the weight of the components during the manufacturing process, facilitate positioning and clamping during processing. Reducing the weight of the components helps to reduce the overall load of the equipment, reduce energy consumption, and at the same time reduce the load on the drive shaft, increase the service life of the drive shaft.
