Description

Technical Field

[0001] This utility model belongs to the field of sesame planting technology, and in particular relates to a screening device for sesame planting. Background Technology

[0002] Sesame seeds are harvested after ripening in the fields, dried in the sun, and the sesame seeds fall off. After being sieved, they are stored.

[0003] Utility model patent CN203678679U discloses a cam-structured sesame screening device, including a screen body and a screening device base. Guide rods are arranged around the screen body. The screen body consists of a screen mesh and a collecting plate, with the screen mesh located above the collecting plate. The collecting plate extends outward relative to the screen mesh to form a discharge port. The screening device base is arranged below the screen body. The screening device base includes a base plate, on which a motor is installed. A small pulley is installed at the output shaft end of the motor. The small pulley and a large pulley form a belt drive linkage device. A cam is arranged coaxially with the large pulley above the base plate. When screening sesame, impurities such as stems and leaves are also screened along with the sesame. When there are too many sesame seeds, the screening pressure of the device will increase, reducing its service life. Furthermore, the sesame seeds are not quantitatively collected after screening, which can easily cause accumulation. Therefore, a screening device for sesame cultivation is proposed.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figures 1 to 6The sesame planting screening equipment of this utility model includes a base plate 1, a controller 2 mounted on the base plate 1, a fixed platform 3 fixedly connected to the base plate 1, a feeding rack 4 fixedly connected to the fixed platform 3, a transport frame 5 fixedly connected to the fixed platform 3, a first fixed frame body 6 fixedly connected to the transport frame 5, a first drive motor 7 fixedly mounted on the first fixed frame body 6, a first rotating shaft 8 rotatably connected to the transport frame 5, the first rotating shaft 8 being connected to the output shaft of the first drive motor 7, and a first conveying wheel 9 rotatably connected to the transport frame 5, the first conveying wheel 9 being connected to the first rotating shaft 8. The transport frame 5 is rotatably connected to a second conveyor wheel 10. A conveyor belt 11 is connected between the first conveyor wheel 9 and the second conveyor wheel 10. The conveyor belt 11 is used to transport sesame seeds. A baffle 12 is fixedly connected to the transport frame 5. The baffle 12 is used to block stem and leaf impurities. Two first fixed rods 13 are fixedly connected to the transport frame 5. A second fixed frame body 14 is fixedly connected to the transport frame 5. A first electric push rod 15 is fixedly installed on the second fixed frame body 14. A pusher plate 16 is slidably connected between the two first fixed rods 13. The pusher plate 16 is connected to the first electric push rod 15 via a telescopic rod. Next, the pusher plate 16 is used to push out stem and leaf impurities. A screening box 17 is fixedly connected to the bottom plate 1. A discharge pipe is fixedly connected to the screening box 17. A filter screen frame 18 is slidably connected inside the screening box 17. The filter screen frame 18 is used to screen sesame seeds. A spring 19 connects the screening box 17 and the filter screen frame 18. Two third fixed frames 20 are fixedly installed on the screening box 17. A second drive motor 21 is fixedly installed on the third fixed frame 20. A second rotating shaft 22 is connected to the output shaft of the second drive motor 21. The second rotating shaft 22 is rotatably connected to the screening box 17. A cam 23 is connected to the second rotating shaft 22. The cam 23 cooperates with the filter screen frame 18. An electric valve 24 is installed on the discharge pipe of the screening box 17. A fourth fixed frame 26 is fixedly connected to the bottom plate 1. A second electric push rod 27 is fixedly installed on the fourth fixed frame 26. A connecting rod 28 is connected to the telescopic rod of the second electric push rod 27. A conveying table 29 is connected to the connecting rod 28. The conveying table 29 has a groove. A weight sensor 30 is installed on the conveying table 29. The weight sensor 30 is used to detect the weight of sesame seeds. Multiple sliding wheels 31 are installed on the conveying table 29.

[0020] Two second fixing rods 25 are fixedly connected to the base plate 1, and the second fixing rods 25 are slidably connected to the conveying table 29.

[0021] Storage bins 32 are placed on the conveyor 29.

[0022] The working principle of this utility model is as follows: the first drive motor drives the first rotating shaft, the first conveyor wheel, the second conveyor wheel and the conveyor belt to rotate. Then, sesame seeds are put into the conveyor belt, and the conveyor belt transports the sesame seeds. After the sesame seeds are transported to contact the baffle, they will fall into the unloading frame through the baffle and then slide into the screening box through the unloading frame. The sesame stems and leaves will be blocked by the baffle, thus completing the initial sesame screening work and screening out larger impurities in the sesame seeds, thereby reducing the working pressure of screening sesame seeds.

[0023] The second drive motor drives the second rotating shaft and cam to rotate. After the cam rotates to contact the filter screen frame, it drives the filter screen frame to move upward. The spring deforms, and after the cam rotates and disengages from the filter screen frame, the spring returns to its original position, thereby driving the filter screen frame to move downward. Through the raising and lowering of the filter screen frame, the sesame seeds are vibrated and screened. Qualified sesame seeds will fall into the storage box through the screening box, while unqualified sesame seeds will remain on the filter screen frame.

[0024] When the weight of sesame seeds in the storage bin reaches the preset threshold of the weight sensor, the first and second drive motors are stopped. At the same time, the electric valve is closed to shut off the discharge pipe channel of the screening box. The second electric push rod stops after working for a certain period of time. The second electric push rod drives the connecting rod, conveyor table, sliding wheel, and storage bin to move. After the conveyor table reaches the designated position, the storage bin is removed from the conveyor table. Then, the empty storage bin is placed back into the conveyor table. Next, the second electric push rod reverses and stops after working for a certain period of time. The second electric push rod drives the connecting rod, conveyor table, sliding wheel, and storage bin to move in the reverse direction to the reset position, so that the storage bin is located below the discharge pipe of the screening box. Then, the electric valve is opened to open the discharge pipe channel of the screening box.

[0025] When there are too many impurities on the conveyor belt, the first electric push rod is controlled to move the pusher plate, so that the pusher plate pushes the impurities on the conveyor belt and pushes them off the conveyor belt, preventing the impurities from affecting the normal operation of the conveyor belt. After the impurities are pushed off, the first electric push rod is controlled to move the pusher plate in the opposite direction to the reset position.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
