DETAILED DESCRIPTION

[0026] The embodiment of the utility model is described in detail below in combination with the drawings.

[0027] As Figures 1-3 , in the embodiment one, a potato sowing machine missing sowing compensation device, comprising

[0028] Sowing pipe 10, the side wall is provided with first photoelectric sensor 20;

[0029] A plurality of compensation pipes 30, the lower port has connecting pipe 31 that communicates with sowing pipe 10 respectively, the connecting pipe 31 is obliquely arranged, and the compensation pipe 30 is provided with rotating port 61;

[0030] Storage hopper 40, the lower end pipe is inserted into the upper end pipe of compensation pipe 30;

[0031] Elastic connecting assembly for connecting storage hopper 40 and compensation pipe 30;

[0032] Vibrator 80 is arranged on the outer wall of storage hopper 40;

[0033] Cover 52 is arranged on the side wall of compensation pipe 30 and is communicated with compensation pipe 30;

[0034] The clamp 50 is movably installed inside the cover 52 and is used to extend into the compensation tube 30 to clamp the potato.

[0035] The second photoelectric sensor 70 is disposed on the side wall of the compensation tube 30, and the second photoelectric sensor 70 is located between the cover 52 and the rotating port 61.

[0036] A baffle 60 is rotatably mounted on the outer wall of the compensation tube 30. The baffle 60 can enter and exit the rotating port 61 to block or release potatoes.

[0037] This embodiment is implemented as follows:

[0038] When this application is in use, if the first photoelectric sensor 20 does not detect any falling potatoes, the baffle 60 rotates and moves away from the rotation port 61. At this time, the potato at the bottom of the compensation tube 30 will fall and enter the sowing tube 10 through the connecting pipe 31 for compensation sowing. Then the baffle 60 returns to its original position, and the clamping plate 50 moves to release the clamped potato. The second to last potato will fall onto the baffle 60 and become the last potato. The clamping plate 60 will move again to clamp the falling second to last potato. At this time, the second photoelectric sensor 70 can detect the potato again. If the second photoelectric sensor 70 does not detect the potato, the other compensation tube 30 will be in a standby state. By setting multiple compensation tubes 30, the situation of missed sowing by the compensation tube 30 can be avoided.

[0039] The vibrator 80 in this application can drive the storage hopper 40 to vibrate, making the potatoes in the storage hopper 40 enter the compensation pipe 30 more smoothly and less prone to blockage.

[0040] The height of the first photoelectric sensor 20 in this application is much higher than the height of the second photoelectric sensor 70.

[0041] The advantage of this application compared to the prior art is that it is not affected by the vibration of the seeder, thus reducing the possibility of missed seeding by the compensating seeder.

[0042] Please see Figure 2 , 3 The outer wall of the clamping plate 50 is fitted with a cloth sleeve 50, and the other end of the cloth sleeve 50 is located at the connection between the cover 52 and the compensation pipe 30.

[0043] The cloth cover 50 prevents potatoes from getting stuck and also prevents potatoes from falling directly onto the clamp 50.

[0044] Please see Figure 1 , 2 3. The clamping plate 50 is connected to the inner wall of the cover 52 by a spring 53. An electromagnet 54 is provided on the outer wall of the cover 52. The clamping plate 50 is an iron plate.

[0045] The electromagnet 54 can adsorb the clamp plate 50, so that the clamp plate 50 compresses the spring 53 into the cover 52, thereby driving the clamp plate 50 to move.

[0046] Please refer to Figure 1 , 2 , 3, the outer wall of the compensation pipe 30 is fixedly connected with the mounting plate 63, the mounting plate 63 is fixedly connected with the servo motor 62, and the output end of the servo motor 62 is fixedly connected with the baffle 60.

[0047] The servo motor on the mounting plate 63 outside the compensation pipe 30 can drive the baffle to rotate, so that the baffle enters and exits the rotating opening.

[0048] Please refer to Figure 1 , the elastic connection assembly comprises a second fixing ring 43 fixedly sleeved on the outer wall of the compensation pipe 30 and a first fixing ring 41 fixedly sleeved on the outer wall of the storage hopper 40, and the first fixing ring 41 and the second fixing ring 43 are connected through a plurality of damping springs 42.

[0049] The first fixing ring 41 on the storage hopper 40 and the second fixing ring 43 on the compensation pipe 30 are connected through the damping springs 42, so that the vibration amplitude of the storage hopper 40 can be controlled, and elastic connection is realized.

[0050] The above is only the preferred embodiment of the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the creative concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
