[0007] The present invention can be further configured such that two stirring blades are rotatably connected inside the box, a cross bar is fixed inside the box, the two stirring blades penetrate the cross bar and the cross bar provides support for the stirring blades, and a second gear is provided at the bottom of the stirring blades.

[0008] The present invention can be further configured as follows: a hollow disk is fixed on the top of the second electric telescopic rod, a socket is provided on the inner side of the hollow disk, a threaded rod is rotatably connected to the inside of the cross rod, a circular disk is fixed to the bottom of the threaded rod, a third electric telescopic rod is installed inside the circular disk, and the threaded rod passes through the screen and is rotatably connected to the cross plate.

[0011] The present invention may be further configured such that a box cover is disposed on the top of the box body, and a handle is disposed on the top of the box cover.

[0012] The raw material ratio method for processing cadmium zinc telluride crystal is as follows:

[0013] S1: Put the raw materials for processing CdZnTe crystals into the electronic scale, weigh the amount needed, and complete the proportion of the raw materials by weighing;

[0014] S2: Open the box cover and pour the proportioned raw materials from the top of the box to mix, and then the raw materials fall to the top of the screen. Since one side of the top of the screen is inclined, the raw materials will move toward the screen hole, and then the small particles will pass through the screen holes, and then the large particles will remain on the top of the screen, which is conducive to the screening of the raw materials. The small particles that pass through the screen holes fall to the bottom of the box, and then the large particles on the top of the screen are taken out. The small particle volume is convenient for the next step of mixing, so the raw materials need to be screened by size. The large particles taken out are crushed into small volumes by the crusher and then put into the top of the screen. Repeat the above operation until there is no large particle raw material;

[0015] S3: The motor starts to drive the second electric telescopic rod and the first gear to rotate, and the rotation of the first gear drives the stirring blade to rotate to stir the raw materials to make them mixed and react. After mixing, the collection container is placed at the bottom of the hopper, and then the first electric telescopic rod drives the sealing plate to leave the discharge port, and then the reacted material is discharged from the discharge port and contained in the container;

[0016] S4: The output end of the second electric telescopic rod extends to drive the hollow disk to rise, and then the hollow disk wraps the round disk. After that, the output end of the third electric telescopic rod in the round disk extends into the inside of the jack, which is conducive to completing the connection between the hollow disk and the threaded rod. Therefore, at this time, the rotation of the motor can drive the threaded rod to rotate. Since the threaded rod is connected to the cross plate in rotation, it will drive the cross plate and the tamping rod to descend. The tamping rod descends and penetrates the sieve hole, and the raw materials blocking the sieve hole are pushed out to prevent blockage.

[0017] The beneficial effects of the present invention are:

[0018] 1. Put the raw materials for processing cadmium zinc telluride crystals into the electronic scale, weigh as much as you need, and complete the proportioning of the raw materials by means of weighing. Open the box cover and pour the proportioned raw materials from the top of the box to mix them, and then the raw materials fall to the top of the screen. Since one side of the top of the screen is inclined, the raw materials will move toward the screen holes, and then the small particles of raw materials will pass through the screen holes of the screen, and then the large particles of raw materials will remain on the top of the screen, which is conducive to the screening of the raw material size. The small particles of raw materials passing through the screen holes fall to the bottom of the box, and then the large particles on the top of the screen are taken out. The small particle volume is convenient for the next step of mixing, so the raw materials need to be screened by size. The large particles taken out are crushed into small volumes by a crusher and then put into the top of the screen, and then enter the bottom of the box through the screen holes. Repeat the above operation until there are no large particles of raw materials.

[0019] 2. After opening the box cover and pulling out the piston, connect the high-pressure nozzle to the water pipe. When the second electric telescopic rod rotates, the first bevel gear rotates with it, and then the second bevel gear drives the rotating shaft to rotate. When the rotating shaft rotates, the lead screw is driven to rotate under the action of the belt drive. When the lead screw rotates, the threaded block and the high-pressure nozzle move. The square tube penetrates the threaded block to limit it to prevent the threaded block from rotating with the lead screw. The high-pressure nozzle moves while spraying water, which is beneficial to increase the spraying range and improve the cleaning effect. The water sprayed from the high-pressure nozzle rushes to the screen to clean the screen. At the same time, the water can flow out of the screen and stay inside the box to soak the box to clean the box. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1-2 A raw material proportioning device for processing cadmium zinc telluride crystals is shown, comprising: a box body 1, a box cover 36 is provided on the top of the box body 1, a handle is provided on the top of the box cover 36, a hopper 2 is provided on one side of the box body 1, a discharge port 3 is provided on the side wall of the box body 1, the discharge port 3 is located inside the hopper 2, and an electronic scale 4 is installed on the top of the hopper 2; a first electric telescopic rod 6 is installed on the side wall of the hopper 2, the hopper 2 is slidably connected with an arc-shaped sealing plate 7, one end of the first electric telescopic rod 6 is fixedly connected to the sealing plate 7, and the sealing plate 7 in the initial state completely seals the discharge port 3.

[0030] like Figure 3-6 The box body 1 shown in the figure provides supporting force through the supporting legs 8, and a mixing mechanism is arranged inside the box body 1, and the mixing mechanism includes a supporting rod 9 fixed on the inner side of the supporting leg 8, and a motor 10 is installed through the supporting rod 9, and a second electric telescopic rod 11 is fixed to the output end of the motor 10, and the output end of the second electric telescopic rod 11 is located inside the box body 1 and fixed with a first gear 12; two stirring blades 14 are rotatably connected inside the box body 1, and a cross bar 15 is fixed inside the box body 1, and the two stirring blades 14 penetrate the cross bar 15 and provide supporting force for the stirring blades 14 through the cross bar 15; a second gear 16 is arranged at the bottom of the stirring blade 14, and the first gear 12 is always meshed with the second gear 16.

[0031] Second electric telescopic rod Third electric telescopic rod A hollow disk 17 is fixed to the top of the second electric telescopic rod 11, and a socket 18 is provided on the inner side of the hollow disk 17. A threaded rod 19 is rotatably connected to the inside of the cross bar 15, and a disc 20 is fixed to the bottom of the threaded rod 19. A third electric telescopic rod 21 is installed inside the disc 20, and an output end of the third electric telescopic rod 21 can extend out of the disc 20. A sealing ring is provided at the connection between the disc 20 and the output end of the third electric telescopic rod 21, and the diameter of the third electric telescopic rod 21 is smaller than the diameter of the socket 18.

[0032] A screen 22 is fixed on the top of the box 1, and a screen hole 23 is set on one side of the screen 22. A horizontal plate 25 is slidably connected to the inner wall of the top of the box 1 in the vertical direction. A tamping rod 26 is fixed to the bottom of the horizontal plate 25. The diameter of the tamping rod 26 is smaller than the diameter of the screen hole 23. The threaded rod 19 passes through the screen 22 and is rotatably connected to the horizontal plate 25. The other side of the screen 22 is inclined and a piston 35 that can be removed is set at the inclined position. A square tube 32 is fixed on the top of the box 1. A threaded block 33 is rotatably connected to the outside of the screw rod 31, and the square tube 32 passes through the threaded block 33 to limit it to prevent the threaded block 33 from rotating with the screw rod 31. A high-pressure nozzle 34 is set at the bottom of the threaded block 33.

[0033] The output end of the second electric telescopic rod 11 extends to drive the hollow disk 17 to rise, and then the hollow disk 17 wraps the disc 20. After that, the output end of the third electric telescopic rod 21 in the disc 20 extends into the inside of the jack 18, which is conducive to completing the connection between the hollow disk 17 and the threaded rod 19. Therefore, at this time, the rotation of the motor 10 can drive the threaded rod 19 to rotate. Since the threaded rod 19 is rotatably connected to the cross plate 25, the cross plate 25 and the tamping rod 26 will be driven to descend. The tamping rod 26 descends and penetrates the sieve hole 23 to prevent blockage.

[0034] A cleaning mechanism is provided inside the box body 1, and the cleaning mechanism includes a first bevel gear 28 provided outside the second electric telescopic rod 11, and the support leg 8 is rotatably connected to the second bevel gear 30 through a rotating shaft 29, and the second bevel gear 30 is always engaged with the first bevel gear 28, and a first pulley is fixed to one end of the rotating shaft 29, and a screw rod 31 is rotatably connected to the top of the box body 1, and a second pulley is fixed to one end of the screw rod 31, and the first pulley and the second pulley are connected by a belt.

[0035] Working principle: put the raw materials for processing cadmium zinc telluride crystals into the electronic scale 4, weigh as much as needed, complete the proportioning of the raw materials by means of weighing, then open the box cover 36 and pour the proportioned raw materials from the top of the box body 1 to mix, and then the raw materials fall to the top of the screen 22. Since one side of the top of the screen 22 is inclined, the raw materials will move toward the screen hole 23, and then the small particles of raw materials will pass through the screen hole 23 of the screen 22, and then the large particles of raw materials will remain on the top of the screen 22, which is conducive to the screening of the raw material size, and the small particles of raw materials passing through the screen hole 23 fall to the bottom of the box body 1; then take out the large particles on the top of the screen 22, the small particle volume is convenient for the next step of mixing, so the raw materials need to be screened by size, the large particles taken out are crushed into small volumes by a crusher and then put into the top of the screen 22, and then enter the bottom of the box through the screen hole 23, and repeat the above operation until there is no large particle raw material.

[0036] The motor 10 is started to drive the second electric telescopic rod 11 and the first gear 12 to rotate. The rotation of the first gear 12 drives the stirring blade 14 to rotate to stir the raw materials to make them mixed and react. After mixing, the collection container is placed at the bottom of the hopper 2, and then the first electric telescopic rod 6 drives the sealing plate 7 to leave the discharge port 3, and then the reacted material is discharged from the discharge port 3 and contained in the container.

[0037] When the sieve holes 23 of the screen 22 and the inner wall of the box body 1 need to be cleaned, the output end of the second electric telescopic rod 11 extends to drive the hollow disk 17 to rise, and then the hollow disk 17 wraps the disc 20. After that, the output end of the third electric telescopic rod 21 in the disc 20 extends into the inside of the jack 18, which is conducive to completing the connection between the hollow disk 17 and the threaded rod 19. Therefore, at this time, the rotation of the motor 10 can drive the threaded rod 19 to rotate. Since the threaded rod 19 is rotatably connected to the cross plate 25, the cross plate 25 and the tamping rod 26 will be driven to descend. The tamping rod 26 descends and penetrates the sieve holes 23, which is conducive to ejecting the raw materials blocking the sieve holes 23 to solve the blockage problem.

[0038] The cleaning of the box body 1 is carried out when the raw materials inside the box body 1 are completely discharged. After the box cover 36 is opened and the piston 35 is pulled out, the high-pressure nozzle 34 is connected to the water pipe. When the second electric telescopic rod 11 rotates, the first bevel gear 28 rotates accordingly, and then the second bevel gear 30 drives the rotating shaft 29 to rotate. When the rotating shaft 29 rotates, the screw rod 31 is driven to rotate under the action of the belt drive. When the screw rod 31 rotates, the threaded block 33 and the high-pressure nozzle 34 move. The square tube 32 penetrates the threaded block 33 to limit it to prevent the threaded block 33 from rotating with the screw rod 31. The high-pressure nozzle 34 moves while spraying water, which is conducive to increasing the range of spraying and improving the cleaning effect. The water sprayed by the high-pressure nozzle 34 rushes to the screen 22 to clean the screen 22. At the same time, the water can flow out of the screen 22 and remain in the inside of the box body 1 to soak the box body 1 to achieve the cleaning of the box 1.

[0039] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
