DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses a material crushing and screening device. Figure 1 The material crushing and screening equipment includes a bracket 1, a crushing bin 2, a crushing mechanism 3 and a screening mechanism 4.

[0031] The upper part of the crushing bin 2 is semicircular, and the lower part is funnel-shaped. The crushing bin 2 is horizontally fixed on the bracket 1, wherein the top of the crushing bin 2 is provided with a feed port 21 connected to the inner cavity of the crushing bin 2, and the bottom is provided with a discharge port 22 connected to the inner cavity of the crushing bin 2. A transparent observation window 23 is provided on the peripheral wall of the crushing bin 2. One end of the crushing bin 2 is open, and a sealing plate 24 is fixedly connected to the opening by bolts. The size of the sealing plate 24 matches the size of the opening. The screening mechanism 4 includes a sieve plate 41 and a vibration assembly, wherein the sieve plate 41 is generally arc-shaped. The sieve plate 41 passes through the sealing plate 24 in the horizontal direction and is inserted into the crushing bin 2. The sieve plate 41 divides the inner cavity of the crushing bin 2 into two upper and lower chambers. The vibration assembly is provided on the sealing plate 24 of the crushing bin 2, and is used to drive the sieve plate 41 to swing back and forth along its own circumferential extension direction.

[0032] Reference Figure 1-2 The crushing mechanism 3 includes a first rotating rod 31, a second rotating rod 32, a first driving assembly 33, and a second driving assembly 34. The first rotating rod 31 is connected to the crushing bin 2 for transverse rotation. The first rotating rod 31 is provided with crushing blades 311. The first driving assembly 33 is disposed on the bracket 1 and is used to drive the first rotating rod 31 to rotate. The second rotating rods 32 are evenly distributed on the crushing bin 2 around the axis of the first rotating rod 31. The second rotating rods 32 are provided with stirring blades 321, and the ends of the stirring blades 321 are connected to scrapers 322. The end of the scrapers 322 away from the second rotating rod 32 abuts the inner circumferential wall of the sieve plate 41. The second driving assembly 34 is used to drive the second rotating rods 32 to perform circular motion around the axis of the first rotating rod 31.

[0033] During use, the material is fed from the feed port 21 into the crushing chamber 2 above the sieve plate 41. The first drive assembly 33 drives the first rotating rod 31 to rotate, driving the crushing blades 311 to rotate at high speed to crush the material. At the same time, the second drive assembly 34 drives the second rotating rod 32 to perform circular motion around the axis of the first rotating rod 31, so that the material is continuously turned and stirred while being crushed, further improving the material crushing effect. The crushed material remains on the sieve plate 41, and the vibration assembly drives the sieve plate 41 to swing back and forth along its own circumference, so that the material that meets the particle size requirements passes through the mesh of the sieve plate 41 and falls into the lower crushing chamber 2. It is discharged and collected through the discharge port 22. The material with larger particle size continues to be crushed by the crushing mechanism 3 until all the material passes through the sieve plate 41 and falls. The material crushing and screening equipment can realize efficient crushing and screening of materials, ensure uniform particles of the crushed materials, and effectively avoid material blockage through the vibration of the screen plate 41 and the scraping of the scraper 322, thereby improving the screening efficiency; it improves the problem that the repeated taking and placing operations in the crusher and screening mechanism 4 during the processing of Chinese medicinal materials are cumbersome, thereby reducing work efficiency.

[0034] Reference Figure 2 For example, the first drive assembly 33 includes a rotary motor 331, a synchronous pulley 332, and a synchronous belt 333. The rotary motor 331 is mounted on the bracket 1. The synchronous pulley 332 is coaxially connected to the rotary shaft of the rotary motor 331 and the first rotary rod 31, respectively. The synchronous belt 333 is wound around both synchronous pulleys 332. When the rotary motor 331 is activated, the first rotary rod 31 is stably and efficiently driven by the synchronous pulley 332 and synchronous belt 333. The structure is simple and easy to use.

[0035] Reference Figure 3Further, the second driving assembly 34 comprises a driving gear 341, driven gears 342 and an inner ring gear 343, the driving gear 341 is coaxially connected to the first rotating rod 31, the driven gears 342 are coaxially connected to the second rotating rods 32, and the driving gear 341 is engaged with the driven gears 342; the inner ring gear 343 is fixedly connected to the sealing plate 24 on the crushing chamber 2, and the inner ring gear 343 is coaxial with the first rotating rod 31, and the driven gears 342 are engaged with the inner ring gear 343.

[0036] When the first rotating rod 31 rotates, the driving gear 341 rotates, and the driven gears 342 rotate, and since the driven gears 342 are engaged with the inner ring gear 343, the driven gears 342 rotate around the first rotating rod 31, thereby achieving the function requirement of the second driving assembly 34 driving the second rotating rod 32 to rotate around the first rotating rod 31. Since the driving of the second rotating rod 32 is driven by the rotation of the first rotating rod 31, the cost is saved.

[0037] For example, the vibration assembly comprises a third rotating rod 42, a push rod 43 and a power member, the end of the sieve plate 41 passing through the sealing plate 24 is fixedly connected with a connecting rod 44 along the radial direction of the sieve plate 41, the end of the connecting rod 44 away from the sieve plate 41 is rotatably connected with the first rotating rod 31 around the axis of the first rotating rod 31, and a clamping groove 441 is formed in the connecting rod 44 along the radial direction of the sieve plate 41. The third rotating rod 42 is rotatably connected to the sealing plate 24 on the crushing chamber 2, and the third rotating rod 42 is parallel to the first rotating rod 31; the push rod 43 is detachably connected to the third rotating rod 42 by a bolt, the push rod 43 is parallel to the third rotating rod 42, and the push rod 43 is inserted into the clamping groove 441; and the power member is used to drive the third rotating rod 42 to rotate. When the power member drives the third rotating rod 42 to rotate, the push rod 43 fixedly arranged on the third rotating rod 42 slides in the clamping groove 441, thereby driving the sieve plate 41 to reciprocate along the extending direction of the sieve plate 41, and effectively screening the materials.

[0038] Specifically, the power member comprises a first gear 45 and a second gear 46, the first gear 45 is coaxially connected to the first rotating rod 31, and the second gear 46 is coaxially connected to the third rotating rod 42, and the first gear 45 and the second gear 46 are engaged. When the first rotating rod 31 rotates, the first gear 45 rotates, thereby driving the second gear 46 to rotate, thereby achieving the function requirement of driving the third rotating rod 42 to rotate, and saving the power cost by sharing the power source of the rotating motor 331.

[0039] The implementation principle of the material crushing and screening equipment in the embodiment of the application is as follows: in use, Chinese herbal medicine is input into the crushing chamber 2 cavity above the sieve plate 41 from the feeding port 21, the rotating motor 331 is started, and the first rotating rod 31 is driven to rotate under the transmission of the synchronous wheel 332 and the synchronous belt 333, thereby crushing the materials.

[0040] As the first rotating rod 31 rotates, it drives the driving gear 341 to rotate, and drives the driven gear 342 to rotate. Since the driven gear 342 is engaged with the inner ring gear 343, the driven gear 342 rotates while making a circular motion around the axis of the first rotating rod 31, thereby uniformly stirring the material being crushed, making the material crushed more evenly and fully, and improving the crushing effect and efficiency.

[0041] Moreover, when the first rotating rod 31 rotates, it drives the first gear 45 to rotate, drives the second gear 46 to rotate, and drives the third rotating rod 42 to rotate. The lever 43 fixed on the third rotating rod 42 will slide in the card slot 441 as the third rotating rod 42 rotates, thereby driving the screen plate 41 to swing back and forth along its own extension direction, thereby achieving effective screening of the material. The material that meets the particle size requirements passes through the mesh of the screen plate 41 and falls into the lower crushing bin 2 chamber, and is discharged and collected through the discharge port 22. The material with a larger particle size continues to be crushed by the crushing mechanism 3 until all the material falls through the screen plate 41. The material crushing and screening equipment of the present application does not require the repeated placement and removal of Chinese medicinal materials in the crusher and screening mechanism 4, thereby improving the efficiency and effect of the crushing and screening of Chinese herbal medicines.

[0042] The above are all optional embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
