Description

Technical Field

[0001] The utility model relates to the technical field of potato harvesting equipment, in particular to a vibration device of a potato harvester. Background Art

[0002] Potatoes are annual herbs of the Solanaceae family. Potatoes have multiple characteristics such as food, vegetables and fruits, so they have become one of the important food varieties in many countries in the world and are listed among the seven major food crops, second only to rice, corn and wheat. When harvesting potatoes, the soil attached to their surface needs to be removed, so a special vibration device is used.

[0003] The vibration device of the existing potato harvester generally digs out the potatoes and puts them into the screening frame and vibrates them to separate the potatoes from the soil. However, during the separation process, due to the rapid vibration of the screening frame, the soil and potatoes inside it are easy to fly out when moving to the exit of the screening frame, which can easily cause damage to the operator's legs, thereby affecting the operator's normal advancement of the harvester. In addition, the screened potatoes will scatter on the ground after leaving the screening frame. In order to avoid stepping on the potatoes, this will also affect the operator's normal progress. For this reason, we provide a vibration device for a potato harvester. Utility Model Content

[0004] In order to solve the problem in the above-mentioned background technology that soil and potatoes are easily thrown out when moving to the exit of the screening frame and the screened potatoes are scattered on the ground after leaving the screening frame, which affects the normal progress of the operator, the utility model provides a vibration device for a potato harvester.

[0005] The utility model is implemented by the following technical scheme: a vibration device of a potato harvester, comprising:

[0006] A frame body, one side of the top of the frame body is rotatably connected with a rotating shaft, one end of the rotating shaft is coaxially fixedly connected with a transmission gear, the outer sleeve of the transmission gear is provided with a transmission toothed belt, the other end of the rotating shaft is coaxially fixedly connected with a cam, a cross bar is provided below the cam, the bottom of the cross bar is symmetrically fixedly connected with a vertical bar and the vertical bar is slidably connected to the frame body, the outer sleeve of the vertical bar is provided with a spring, a screening frame is hinged on the frame body, a connecting rod is hinged between the screening frame and the cross bar through a hinge, and a rake tooth is fixedly connected to the lower part of one side of the frame body;

[0007] A blocking assembly, the blocking assembly includes a chassis fixedly connected to the frame body through a bracket, the top center of the chassis is rotatably connected to a rotating rod, the frame body is fixedly connected to a motor and the rotor end of the motor is coaxially fixedly connected to the rotating rod, the outside of the rotating rod is equidistantly circumferentially fixedly connected with a baffle, two adjacent groups of baffles are hinged with a fan-shaped receiving plate through a hinge, the top of the chassis is fixedly connected to an annular slide rail, the outside of the annular slide rail is equidistantly slidably connected with a slider, the bottom of the fan-shaped receiving plate is movably connected to a movable block, and a connecting rod is hinged between the movable block and its corresponding slider through a hinge.

[0008] As a further improvement of the above solution, the blocking component further includes:

[0009] The movable groove is arranged at the bottom of the fan-shaped receiving plate, a sliding rod is fixedly connected inside the movable groove and the sliding rod is slidably connected with the movable block, and a spring 2 is sleeved outside the sliding rod.

[0010] As a further improvement of the above solution, a connecting frame is provided between the rake teeth and the screening frame, and the connecting frame is fixedly connected to the frame body.

[0011] As a further improvement of the above solution, a connecting seat is symmetrically fixedly connected to the upper front end of the frame body.

[0012] As a further improvement of the above solution, the radius of the fan-shaped receiving plate is larger than the radius of the chassis.

[0013] As a further improvement of the above solution, the length of the baffle is greater than the radius of the fan-shaped receiving plate.

[0014] As a further improvement of the above solution, one side of the screening frame corresponding to the blocking component is an arc-shaped opening structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model drives the rotating rod to rotate through a motor, so that the baffle plate can be driven to rotate together. The rotating baffle plate can block the soil and potatoes that are detached and fly out, effectively avoiding the situation that the soil and potatoes are easy to fly out when moving to the exit of the screening frame, which may easily cause injuries to the operator's legs, thereby affecting the operator's normal propulsion of the harvester, and the utility model is highly practical.

[0017] 2. The utility model intercepts the flying soil and potatoes through the rotating baffle plate and makes them fall on the fan-shaped receiving plate. Due to the increase in weight, the sliding cooperation between the movable block and the slide rod, and the hinged action between the movable block, the slide bar and the connecting rod, the fan-shaped receiving plate will tilt downward. Due to the pushing effect of the soil and potatoes in the screening frame, the soil and potatoes on the fan-shaped receiving plate will not roll out at this time. However, as the fan-shaped receiving plate continues to rotate, when it rotates to the right side, the soil and potatoes on its surface will automatically slide to one side of the device due to the loss of the obstruction of the soil and potatoes in the screening frame. Not only will it not affect the operator's progress due to preventing the potatoes from being stepped on, but it will also facilitate the subsequent collection of potatoes, further improving the practicability of the device.

[0025] Please combine Figure 1-4 , a vibration device of a potato harvester of this embodiment includes:

[0026] A frame body 1, a rotating shaft is rotatably connected to one side of the top of the frame body 1, one end of the rotating shaft is coaxially fixedly connected to a transmission gear, a transmission belt 2 is provided on the outer sleeve of the transmission gear, a cam 3 is coaxially fixedly connected to the other end of the rotating shaft, a cross bar 4 is provided below the cam 3, a vertical bar 5 is symmetrically fixedly connected to the bottom of the cross bar 4, and the vertical bar 5 is slidably connected to the frame body 1, a spring 6 is provided on the outer sleeve of the vertical bar 5, a screening frame 7 is hinged on the frame body 1, a connecting rod 8 is hinged between the screening frame 7 and the cross bar 4 through a hinge, a rake tooth 9 is fixedly connected to the lower part of one side of the frame body 1, a connecting seat is symmetrically fixedly connected to the upper front end of the frame body 1, which is convenient for connecting with a walking tractor, and the side of the screening frame 7 corresponding to the blocking component is an arc-shaped opening structure, which is convenient for fitting the blocking component;

[0027] The blocking assembly includes a chassis 101 fixedly connected to the frame body 1 through a bracket, a rotating rod 102 is rotatably connected to the top center of the chassis 101, a motor is fixedly connected to the frame body 1 and the rotor end of the motor is coaxially fixedly connected to the rotating rod 102, a baffle 103 is fixedly connected to the outside of the rotating rod 102 in an equidistant circumferential manner, a fan-shaped receiving plate 104 is hinged between two adjacent groups of baffles 103 through a hinge, an annular slide rail 105 is fixedly connected to the top of the chassis 101, a slider 106 is slidably connected to the outside of the annular slide rail 105, a movable block 107 is movably connected to the bottom of the fan-shaped receiving plate 104, a connecting rod 108 is hinged between the movable block 107 and its corresponding slider 106 through a hinge, the radius of the fan-shaped receiving plate 104 is larger than the radius of the chassis 101, and the length of the baffle 103 is larger than the radius of the fan-shaped receiving plate 104.

[0028] The blocking assembly also includes:

[0029] The movable groove is provided at the bottom of the fan-shaped receiving plate 104 , a sliding rod 109 is fixedly connected inside the movable groove and the sliding rod 109 is slidably connected to the movable block 107 , and a spring 110 is sleeved outside the sliding rod 109 .

[0030] The implementation principle of the vibration device of a potato harvester in the embodiment of the present application is as follows: first, the device is connected and fixed to an external walking tractor through a connecting seat, and then the transmission toothed belt 2 is sleeved on the outside of the transmission gear on the walking tractor, and then the walking tractor is started to drive the device to move, and the rake teeth 9 can dig out the potatoes under the ground, and as the device is continuously advanced, the soil and potatoes excavated first will be pushed into the screening frame 7 by the soil and potatoes excavated later, and the rotation of the transmission gear on the walking tractor can drive the transmission gear on the device to rotate together, thereby The cam 3 can be driven to rotate, and the rotation of the cam 3 will regularly squeeze the cross bar 4. The sliding cooperation between the vertical bar 5 and the frame body 1 and the rebound effect of the spring 6 make the cross bar 4 move back and forth vertically. The cross bar 4 and the hinged connection between the screening frame 7 and the connecting rod 8 can drive the screening frame 7 to swing left and right. The generated vibration can remove the soil attached to the surface of the potato. Then the motor is started, and the rotating rod 102 is driven by the motor to rotate, so that the baffle 103 can be driven to rotate together. The rotating baffle 103 can remove the detached and flying soil and potatoes. The rotating baffle 103 intercepts the flying soil and potatoes and makes them fall on the fan-shaped receiving plate 104. Due to the increase in weight, the sliding cooperation between the movable block 107 and the slide bar 109, and the hinged cooperation between the movable block 107 and the slide bar 106 and the connecting rod 108, the fan-shaped receiving plate 104 will tilt downward. Due to the pushing effect of the soil and potatoes in the screening frame 7, the soil and potatoes on the fan-shaped receiving plate 104 will not roll out. However, as the fan-shaped receiving plate 104 continues to rotate, when it rotates to the right, As the dirt and potatoes in the screening frame 7 are no longer blocking the dirt and potatoes, the dirt and potatoes on the surface of the screening frame 7 will automatically slide to one side of the device. Due to the reduction in weight, the fan-shaped receiving plate 104 will automatically reset itself due to the rebound effect of the spring 2 110. As the annular rail 105 and the slider 106 fit together, the slider 106 can automatically push the dirt away when sliding on the annular rail 105. Therefore, the dirt will not affect the sliding of the slider 106 on the annular rail 105. Therefore, the dirt will not affect the rotation of the fan-shaped receiving plate 104. Finally, the potatoes can be collected. Example

[0031] Based on Example 1, this embodiment is further improved in that a connecting frame 10 is provided between the rake teeth 9 and the screening frame 7 and the connecting frame 10 is fixedly connected to the frame body 1, so that the dug potatoes can smoothly enter the screening frame 7.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
