Description

Technical Field

[0001] This utility model relates to the field of potato harvester technology, and in particular to an anti-clogging structure for a potato harvester screening conveyor belt. Background Technology

[0002] A potato harvester is an agricultural device used for the mechanized harvesting of potatoes. It is mainly used to dig potatoes out of the soil and separate them from the soil and impurities. By using a potato harvester, the harvesting efficiency of potatoes can be improved, manual labor can be reduced, and the potato damage rate can be reduced. It is an indispensable and important tool in modern potato cultivation.

[0003] During potato harvesting, potatoes harvested from the soil are transported via a screening conveyor belt. During transportation, potatoes are separated from impurities such as soil and stones to ensure potato quality. However, due to the mixing of potatoes and impurities, the conveyor belt is prone to blockage, affecting harvesting efficiency.

[0004] Therefore, to address the problem that the screening conveyor belt is prone to clogging during the separation of potatoes from impurities such as soil and stones, which affects harvesting efficiency, an anti-clogging structure can be installed to clean the conveyor belt during the screening process. This can effectively solve the problem of clogging in the screening conveyor belt and improve the efficiency and quality of potato harvesting. Utility Model Content

[0005] To overcome the problem that during potato harvesting, potatoes are transported from the soil via a screening conveyor belt, which separates potatoes from impurities such as soil and stones to ensure potato quality, but the mixing of potatoes and impurities can easily cause the conveyor belt to become clogged, affecting harvesting efficiency.

[0006] The technical solution of this utility model is as follows: a structure for preventing blockage of a potato harvester screening conveyor belt, including a support base frame, a slag discharge groove on the top surface of the support base frame, a telescopic rod fixedly connected to the top surface of the support base frame, a support spring slidably sleeved on the outer side of the telescopic rod, a support seat fixedly connected to the top surface of the telescopic rod, a screening motor connected and installed on the side of the support base frame, a drive gear fixedly connected to the output end of the screening motor, and a limit groove on the side of the support base frame.

[0007] Preferably, the telescopic rods are symmetrically and alternately distributed on the top surface of the support base, one end of the support spring is fixedly connected to the top surface of the support base, the other end of the support spring is fixedly connected to the bottom surface of the support seat, the support seats are symmetrically distributed on the telescopic rods, and the limiting grooves are symmetrically distributed on the support base.

[0008] Preferably, a screening shaft is rotatably connected to the center of the support base, and a transmission gear is fixedly connected to the outer side of the screening shaft. The transmission gear meshes with the drive gear. A screening cam is fixedly connected to the outer side of the screening shaft. The screening cams are symmetrically distributed on the screening shaft, and the outer side of the screening cams is in contact with the bottom surface of the support base.

[0009] Preferably, a turntable is fixedly connected to the side of the screening shaft, the turntables are symmetrically distributed on the screening shaft, an eccentric shaft is fixedly connected to the side of the turntable, and a rotating connecting rod is rotatably connected to the outer side of the eccentric shaft.

[0010] Preferably, a connecting rod is slidably connected to the inner wall of the limiting groove, the connecting rod is rotatably connected to the rotating connecting rod, a cleaning base plate is fixedly connected to the side of the connecting rod, and a cleaning brush is fixedly connected to the top surface of the cleaning base plate.

[0011] Preferably, a transport motor is connected and installed on the side of the support base, and a drive shaft is fixedly connected to the output end of the transport motor. The drive shaft is rotatably connected to the support base, and a transmission shaft is rotatably connected inside the support base. Drive wheels are symmetrically fixedly connected to the outer sides of the drive shaft and the transmission shaft.

[0012] Preferably, a roller conveyor belt is connected and installed on the outer side of the drive wheel, and a pulley is fixedly connected to the outer side of the end of the drive shaft and transmission shaft away from the transport motor, and a transmission belt is connected and installed on the outer side of the pulley.

[0013] The beneficial effects of this utility model are:

[0014] 1. When using a roller conveyor belt to transport potatoes, the screening motor drives the drive gear to rotate, and the meshing transmission gears drive the screening shaft to rotate, which in turn drives the screening cam to rotate, pushing the support seat to move up and down. This causes the roller conveyor belt to vibrate as the support seat moves, thus vibrating and screening the potatoes during transportation. The vibration force separates impurities from the gaps between the roller conveyor belts, while preventing the roller conveyor belt from clogging.

[0015] 2. As the screening shaft drives the screening cam to rotate, causing the support to vibrate up and down, it also drives the turntables fixedly connected to both ends of the screening shaft to rotate. This, in turn, drives the rotating connecting rod to rotate via the eccentric shaft. The rotating connecting rod pulls the connecting rod to slide back and forth within the limit groove, which in turn drives the cleaning brush to move back and forth via the cleaning base plate. This cleans the vibrating roller conveyor belt and prevents it from becoming clogged. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides an embodiment of an anti-clogging structure for a potato harvester screening conveyor belt, including a support base frame 1, a slag discharge groove 2 on the top surface of the support base frame 1, a telescopic rod 3 fixedly connected to the top surface of the support base frame 1, a support spring 4 slidably sleeved on the outer side of the telescopic rod 3, a support seat 5 fixedly connected to the top surface of the telescopic rod 3, a screening motor 6 connected and installed on the side of the support base frame 1, an active gear 7 fixedly connected to the output end of the screening motor 6, and a limit groove 8 on the side of the support base frame 1.

[0024] The telescopic rods 3 are symmetrically and staggered on the top surface of the support base 1. One end of the support spring 4 is fixedly connected to the top surface of the support base 1, and the other end of the support spring 4 is fixedly connected to the bottom surface of the support seat 5. The support seats 5 are symmetrically distributed on the telescopic rods 3, and the limiting grooves 8 are symmetrically distributed on the support base 1. The telescopic rods 3 provide guidance and limitation for the support seats 5, and the elastic force of the support springs 4 provides support for the support seats 5, assisting the support seats 5 to move up and down.

[0025] A screening shaft 101 is rotatably connected to the center of the support base 1. A transmission gear 102 is fixedly connected to the outer side of the screening shaft 101. The transmission gear 102 meshes with the drive gear 7. A screening cam 103 is fixedly connected to the outer side of the screening shaft 101. The screening cam 103 is symmetrically distributed on the screening shaft 101. The outer side of the screening cam 103 is in contact with the bottom surface of the support base 5. The drive gear 7 is driven to rotate by the screening motor 6. The screening shaft 101 is driven to rotate by the meshing transmission gear 102, which in turn drives the screening cam 103 to rotate and pushes the support base 5 to move up and down, providing power for the vibrating screening of potatoes.

[0026] A turntable 104 is fixedly connected to the side of the screening shaft 101. The turntables 104 are symmetrically distributed on the screening shaft 101. An eccentric shaft 105 is fixedly connected to the side of the turntable 104. A rotating connecting rod 106 is rotatably connected to the outer side of the eccentric shaft 105. When the screening shaft 101 drives the screening cam 103 to rotate, causing the support seat 5 to vibrate up and down, it will drive the turntables 104 fixedly connected to both ends of the screening shaft 101 to rotate. In turn, the rotating connecting rod 106 can be driven to rotate through the eccentric shaft 105.

[0027] A connecting rod 107 is slidably connected to the inner wall of the limiting slide groove 8. The connecting rod 107 is rotatably connected to the rotating connecting rod 106. A cleaning base plate 108 is fixedly connected to the side of the connecting rod 107. A cleaning brush 109 is fixedly connected to the top surface of the cleaning base plate 108. The rotating connecting rod 106 pulls the connecting rod 107 to slide back and forth in the limiting slide groove 8. Thus, the cleaning base plate 108 can drive the cleaning brush 109 to move back and forth, thereby cleaning the vertically vibrating roller conveyor belt 505 and preventing the roller conveyor belt 505 from getting blocked.

[0028] A transport motor 501 is mounted on the side of the support base 5. The output end of the transport motor 501 is fixedly connected to the drive shaft 502. The drive shaft 502 is rotatably connected to the support base 5. A transmission shaft 503 is rotatably connected inside the support base 5. Drive wheels 504 are symmetrically fixedly connected to the outer sides of the drive shaft 502 and the transmission shaft 503. The transport motor 501 drives the drive shaft 502 to rotate, thereby driving the drive wheels 504 to rotate, which facilitates the power supply for the rotation of the roller conveyor belt 505.

[0029] A roller conveyor belt 505 is connected and installed on the outer side of the drive wheel 504. A pulley 506 is fixedly connected to the outer side of the end of the drive shaft 502 and the transmission shaft 503 away from the transport motor 501. A transmission belt 507 is connected and installed on the outer side of the pulley 506. When the transport motor 501 drives the drive shaft 502 to rotate, the power is transmitted through the pulley 506 and the transmission belt 507, so that the drive shaft 502 and the transmission shaft 503 rotate synchronously. In turn, the drive wheel 504 drives the roller conveyor belt 505 to rotate, thereby transporting the potatoes.

[0030] Working principle: According to Figure 1 and Figure 5 As shown, during operation, the transport motor 501 drives the drive shaft 502 to rotate, which in turn drives the pulley 506 to rotate. Power is transmitted through the pulley 506 and the transmission belt 507, causing the drive shaft 502 and the transmission shaft 503 to rotate synchronously. In turn, the drive wheel 504 drives the roller conveyor belt 505 to rotate, thus transporting the potatoes.

[0031] according to Figures 1-4 As shown, the screening motor 6 drives the active gear 7 to rotate, and the meshing transmission gear 102 drives the screening shaft 101 to rotate, which in turn drives the screening cam 103 to rotate, pushes the support seat 5 to move up and down, and causes the roller conveyor belt 505 to vibrate as the support seat 5 moves, thus vibrating and screening the potatoes during transportation.

[0032] according to Figures 1-5 As shown, the screening shaft 101 drives the screening cam 103 to rotate, causing the support base 5 to vibrate up and down. At the same time, it drives the turntable 104 fixedly connected to both ends of the screening shaft 101 to rotate. In turn, the eccentric shaft 105 drives the rotating connecting rod 106 to rotate. The rotating connecting rod 106 pulls the connecting rod 107 to slide back and forth in the limiting slide groove 8. Thus, the cleaning base plate 108 drives the cleaning brush 109 to move back and forth, thereby cleaning the up-and-down vibrating roller conveyor belt 505 and preventing the roller conveyor belt 505 from getting blocked.
