[0007] The utility model provides the following technical solutions:
[0008] A screening device for processing white melon seeds, comprising:
[0009] A base frame, wherein a first screening frame and a second screening frame are respectively provided inside the base frame, two fixing plates are respectively fixedly provided on both sides of the inner wall of the base frame, the four fixing plates are divided into two groups, and a feed hopper corresponding to the first screening frame and the second screening frame is fixedly provided between each group of fixing plates;
[0010] A fine screening mechanism is provided on the first screening frame and the second screening frame for fine screening of white melon seeds;
[0011] The driving mechanism is arranged on the base frame and is used to drive the first screening frame and the second screening frame to perform screening.
[0012] In a possible design, the fine screening mechanism includes four chutes, a coarse screening frame, a melon seed receiving frame, a fine screening frame, an impurity receiving frame, four mounting slots, multiple springs and four limit blocks. The four chutes are respectively opened on the inner walls of the first screening frame and the second screening frame. The coarse screening frame and the melon seed receiving frame are arranged inside the first screening frame and are slidably connected to the inside of two of the chutes. The coarse screening frame is arranged on the top of the melon seed receiving frame. The fine screening frame and the impurity receiving frame are arranged inside the second screening frame and are slidably connected to the inside of the other two chutes. The fine screening frame is arranged on the top of the impurity receiving frame.

The multiple springs are divided into four groups, and each limit block is fixed on the top of each group of springs, which are respectively used to limit and fix the coarse screening frame, melon seed receiving frame, fine screening frame and impurity receiving frame.
[0014] In one possible design, the driving mechanism includes a motor, a reciprocating screw, a threaded block, multiple support legs, multiple pulleys and four slide rails. The motor is fixedly mounted on one side of the base frame, and the output end of the motor passes through one side of the base frame and extends to the interior of the base frame. The output end of the motor is fixed to one end of the reciprocating screw through a coupling, and the threaded block is threadedly connected to the outer wall of the reciprocating screw.

Under the action of the finer screen, tiny impurities are further removed, and the pure white melon seeds remain on the fine screening frame, while finer impurities fall into the impurity holding frame through the screen holes. The installation and disassembly principles of the impurity holding frame and the fine screening frame are the same as those of the coarse screening frame and the holding frame, which also facilitates the removal of the impurity holding frame and the fine screening frame, thereby improving the applicability of processing and enhancing the product quality of the white melon seeds. When the driving mechanism is running, the output end of the motor is connected to the The shaft drives the reciprocating screw to rotate. Since the threaded block is threadedly connected to the outer wall of the reciprocating screw and is fixedly arranged between the first screening frame and the second screening frame, the rotating reciprocating screw will drive the threaded block and the screening frame to reciprocate in the horizontal direction, thereby achieving a stronger screening effect and improving processing efficiency. A pulley is installed on the support leg on the bottom side of the screening frame. The pulley will slide within the slide rail on the bottom side of the inner wall of the base frame, which can reduce the friction resistance during the movement of the screening frame, improve the screening efficiency, and ensure the smooth movement of the screening frame.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0029] Example 1
[0030] Please refer to Figure 1-Figure 4 , a screening device comprising:
[0031] The base frame 1 has a first screening frame 7 and a second screening frame 8 provided inside the base frame 1. Two fixed plates 2 are fixed on both sides of the inner wall of the base frame 1. The four fixed plates 2 are divided into two groups. A feed hopper 3 corresponding to the first screening frame 7 and the second screening frame 8 is fixed between each group of fixed plates 2. The white melon seeds enter the first screening frame 7 through the feed hopper 3. The feed hopper 3 is supported and fixed by the fixed plate 2, which is conducive to the effect of guiding the material without spilling.
[0032] The fine screening mechanism is arranged on the first screening frame 7 and the second screening frame 8 for fine screening of white melon seeds. The fine screening mechanism includes four chutes 11, a coarse screening frame 12, a melon seed receiving frame 13, a fine screening frame 14, an impurity receiving frame 15, four mounting slots 16, multiple springs 17 and four limit blocks 18. The four chutes 11 are respectively opened on the inner walls of the first screening frame 7 and the second screening frame 8. The coarse screening frame 12 and the melon seed receiving frame 13 are arranged inside the first screening frame 7 and slidably connected to the inside of two of the chutes 11. The coarse screening frame 12 is arranged on the top of the melon seed receiving frame 13. The first screening frame 7 vibrates to make the white melon seeds roll and jump on the coarse screening frame 12. Larger impurity particles will remain on the coarse screening frame 12, and the white melon seeds will fall into the melon seed receiving frame 13 through the sieve holes. The white melon seeds can be stored through the melon seed receiving frame 13 for subsequent processing. The fine screening frame 14 and the impurity holding frame 15 are arranged inside the second screening frame 8 and are slidably connected to the inside of the other two chutes 11. The fine screening frame 14 is arranged on the top of the impurity holding frame 15. The white melon seeds that have undergone preliminary screening are then poured into the fine screening frame 14 of the second screening frame 8. Under the action of the finer screen, tiny impurities are further removed. The pure white melon seeds remain on the fine screening frame 14, while finer impurities fall into the impurity holding frame 15 through the sieve holes.
[0033] The four mounting grooves 16 are respectively opened on the bottom sides of the inner walls of the four slide grooves 11, and multiple springs 17 are respectively fixedly arranged on the bottom sides of the inner walls of the mounting grooves 16. The multiple springs 17 are divided into four groups, and each limit block 18 is fixedly arranged on the top end of each group of springs 17, which are respectively used to limit and fix the coarse screening frame 12, the melon seed receiving frame 13, the fine screening frame 14 and the impurity receiving frame 15. The combination of the springs 17 and the limit blocks 18 installed on the bottom sides of the slide grooves 11 provides the necessary elastic support and limit fixation for the screening frame, ensuring that the screening frame remains stable during the vibration process, preventing the screening effect from being affected by excessive shaking, and achieving the effect of convenient installation and removal, improving convenience, being conducive to cleaning large particles of impurities, and conveniently pouring the white melon seeds in the melon seed receiving frame 13 into the second screening frame 8, thereby also facilitating the removal of the impurity receiving frame 15 and the fine screening frame 14, thereby improving the applicability of processing and enhancing the product quality of the white melon seeds.
[0034] The driving mechanism is arranged on the base frame 1 for driving the first screening frame 7 and the second screening frame 8 for screening. The driving mechanism includes a motor 4, a reciprocating screw 5, a threaded block 6, multiple support legs 9, multiple pulleys 10 and four slide rails 19. The motor 4 is fixedly installed on one side of the base frame 1. The output end of the motor 4 passes through one side of the base frame 1 and extends to the interior of the base frame 1. The output end of the motor 4 is fixed to one end of the reciprocating screw 5 through a coupling. The threaded block 6 is threadedly connected to the outer wall of the reciprocating screw 5. The threaded block 6 is fixed between the first screening frame 7 and the second screening frame 8.
[0035] The output end of the motor 4 drives the reciprocating screw 5 to rotate through the coupling. Since the threaded block 6 is threadedly connected to the outer wall of the reciprocating screw 5 and is fixedly arranged between the first screening frame 7 and the second screening frame 8, the rotating reciprocating screw 5 will drive the threaded block 6 and the screening frame to reciprocate in the horizontal direction, thereby achieving a stronger screening effect and improving processing efficiency.
[0036] Multiple support legs 9 are respectively fixed on the bottom sides of the first screening frame 7 and the second screening frame 8, each pulley 10 is fixedly installed on the bottom of the support leg 9, and each slide rail 19 is opened on the bottom side of the inner wall of the base frame 1 for the pulley 10 to slide in a limited position. The pulley 10 is installed on the support leg 9 on the bottom side of the screening frame, and the pulley 10 will slide in a limited position within the slide rail 19 on the bottom side of the inner wall of the base frame 1, which can reduce the friction resistance during the movement of the screening frame, improve the screening efficiency, and ensure the smooth movement of the screening frame.
[0037] This application can be used in the field of white melon seed processing, and can also be used in other fields applicable to this application.
