[0031] Specifically, when it is necessary to install the reaction box 1, the side plates 103 are fixedly connected to the front and rear sides of the reaction box 1, and the rod body 104 is placed inside the supporting plate 2, then the sleeve block 301 on the limiting assembly is pulled upward, the movement of the sleeve block 301 drives the second shaft seat 207 on the docking rod 208 to move through the linkage plate 209, the second shaft seat 207 is fixedly connected to the pressing plate 204, the movement of the second shaft seat 207 drives the pressing plate 204 to move, the movement of the pressing plate 204 drives the sliding seat 203 to slide on the cross rod 205, which increases the stability of the movement of the pressing plate 204, and the movement of the pressing plate 204 facilitates the positioning of the position of the rod body 104, thereby facilitating the installation of the whole reaction box 1.

[0032] As an embodiment in the present embodiment, the limiting assembly comprises a hinged seat 3 rotatably connected to the other end of the linkage plate 209, the hinged seat 3 is fixedly connected to the sleeve block 301, a clamping column 302 is fixedly connected to the surface of the sleeve block 301, a handle 303 is fixedly connected to one end of the clamping column 302, the sleeve block 301 is slidably connected to a limiting rod 304, a sleeve ring 305 is fixedly connected to the bottom end of the limiting rod 304, a first spring 306 is sleeved on the limiting rod 304, the two ends of the first spring 306 are fixedly connected to the bottom surface of the sleeve block 301 and the top surface of the sleeve ring 305 respectively, a top seat 307 is fixedly connected to the surface of the supporting plate 2 at one end of the top seat 307, a third shaft seat 308 is fixedly connected to the top surface of the top seat 307, a top rod 309 is fixedly connected to the third shaft seat 308, a clamping plate 310 is rotatably connected to one end of the top rod 309, a plurality of clamping grooves 311 are arranged in the clamping plate 310, and the clamping column 302 is clamped in one of the clamping grooves 311.

[0033] Specifically, when it is necessary to move the sleeve block 301, the locking plate 310 is first rotated. The rotation of the locking plate 310 causes the locking post 302 to disengage from the inside of the slot 311. Then, the handle 303 is pulled. The pulling of the handle 303 causes the sleeve block 301 to slide on the limiting rod 304 through the locking post 302. When the sleeve block 301 moves to the appropriate position, the locking plate 310 is rotated again. The rotation of the locking plate 310 causes the locking post 302 to be locked inside the corresponding slot 311, thereby facilitating the limiting of the position of the sleeve block 301.

[0034] In one embodiment of this invention, the rocking assembly includes a support plate 4 rotatably connected to a first pin 201. The other end of the support plate 4 is rotatably connected to a slide rod 401. A base plate 402 is provided at the bottom of the slide rod 401. A base 403 is fixedly connected to the base plate 402. A groove 404 is provided on the base 403. Both ends of the slide rod 401 are slidably connected inside the groove 404. A sleeve 405 is fixedly connected to the middle of the slide rod 401. A mating plate 406 is fixedly connected to the surface of the sleeve 405. A sliding plate 407 is fixedly connected to the top of the mating plate 406. Both ends of the sliding plate 407 are slidably connected to a fixed rod 408. One end of the fixed rod 408 is fixedly connected to a bracket 409. The bottom end of the bracket 409 is fixedly connected to... On the base 403, a driven rod 410 is fixedly connected to the middle of one side of the slide plate 407. A retaining ring 411 is fixedly connected to one end of the driven rod 410. A second spring 412 is sleeved on the driven rod 410. The two ends of the second spring 412 are fixedly connected to one side of the retaining ring 411 and one side of the bracket 409, respectively. A positioning plate 413 is fixedly connected to the other side of the slide plate 407. A pulley 414 is rotatably connected to one end of the positioning plate 413. The pulley 414 is attached to the cam 415. The cam 415 is fixedly connected to the top of the transmission rod 416. The transmission rod 416 is rotatably connected to the frame 417. The bottom end of the transmission rod 416 is fixedly connected to the output end of the drive motor 418. The drive motor 418 is fixedly installed in the middle of the base 403.

[0035] Specifically, when it is necessary to shake the entire reaction chamber 1, the drive motor 418 operates to rotate the transmission rod 416. The rotation of the transmission rod 416 drives the cam 415 to rotate. The pulley 414 is attached to the edge of the cam 415 by the elastic force of the second spring 412. The rotation of the cam 415 causes the slide plate 407 to move. The movement of the slide plate 407 drives the slide rod 401 to move through the sleeve 405 on the docking plate 406. The slide rod 401 slides inside the slide groove 404, increasing the stability of the movement of the slide rod 401. The movement of the slide rod 401 pushes the support plate 2 on the first pin 201 to shake up and down rapidly through the support plate 4, thereby making the reaction inside the reaction chamber 1 more uniformly mixed.

[0036] The working principle of this invention is as follows: When it is necessary to install the reaction chamber 1, side plates 103 are fixedly connected to the front and rear sides of the reaction chamber 1, and rods 104 are fixedly connected to the side plates 103. The rods 104 are placed inside the support plate 2, and then the sleeve block 301 on the limiting component is pulled upward. The movement of the sleeve block 301 pushes the second shaft seat 207 on the docking rod 208 to move through the linkage plate 209. The second shaft seat 207 is fixedly connected to the pressure plate 204. The movement of the second shaft seat 207 causes the pressure plate 204 to move. The movement of the pressure plate 204 causes the slide block 203 to slide on the crossbar 205, increasing the stability of the movement of the pressure plate 204. The movement of the pressure plate 204 facilitates the limiting of the position of the rod 104, thereby facilitating the overall installation of the reaction chamber 1.

[0037] When it is necessary to move the sleeve block 301, firstly rotate the locking plate 310. The rotation of the locking plate 310 causes the locking post 302 to disengage from the inside of the slot 311. Then, pull the handle 303. The pulling of the handle 303 causes the sleeve block 301 to slide on the limiting rod 304 through the locking post 302. When the sleeve block 301 moves to the appropriate position, the locking plate 310 is rotated again. The rotation of the locking plate 310 causes the locking post 302 to be locked in the corresponding slot 311, thereby facilitating the limiting of the position of the sleeve block 301.

[0038] When it is necessary to shake the entire reaction chamber 1, the drive motor 418 operates to rotate the transmission rod 416. The rotation of the transmission rod 416 drives the cam 415 to rotate. The pulley 414 is attached to the edge of the cam 415 by the elastic force of the second spring 412. The rotation of the cam 415 causes the slide plate 407 to move. The movement of the slide plate 407 drives the slide rod 401 to move through the sleeve 405 on the docking plate 406. The slide rod 401 slides inside the slide groove 404, increasing the stability of the movement of the slide rod 401. The movement of the slide rod 401 pushes the support plate 2 on the first pin 201 to shake up and down rapidly through the support plate 4, thereby making the reaction inside the reaction chamber 1 more uniformly mixed.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
