DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0019] like Figure 1 and Figure 2As shown, this embodiment discloses a crushing and grinding device for processing Chinese medicinal materials, including a mounting box 1, a mounting frame 2 is arranged on one side of the outer surface of the mounting box 1, a motor 3 is arranged in the middle of the inner cavity of the mounting box 1, a control component 4 is arranged on one side of the upper end of the mounting box 1, a transmission component 5 is arranged on the other side of the upper end of the mounting box 1, a screening component 6 is arranged in the middle of the upper end of the mounting frame 2, a primary crushing device 7 is arranged on the upper end of the screening component 6, and the primary crushing device 7 and the screening component 6 are connected to the transmission component 5 through corresponding transmission mechanisms.

[0020] Specifically, in the process of crushing the Chinese medicinal materials, first, the motor 3 is controlled to operate through the control component 4, so that the motor 3 drives the primary crushing device 7 to operate through the transmission component 5. Then the staff can put the Chinese medicinal materials into the primary crushing device 7, and the primary crushing device 7 will perform preliminary crushing on the Chinese medicinal materials. After the primary crushing device 7 performs preliminary crushing on the Chinese medicinal materials, the Chinese medicinal materials will fall to the upper part of the screening component 6.

[0021] Furthermore, when the motor 3 drives the primary crushing device 7 to operate through the transmission component 5, the transmission component 5 will also drive the screening component 6 to operate. When the initially crushed Chinese medicinal materials fall on the upper part of the screening component 6, the screening component 6 can perform preliminary screening on the initially crushed Chinese medicinal materials.

[0022] After the primary pulverizing device 7 preliminarily pulverizes the Chinese medicinal materials, in order to screen the pulverized medicinal materials, Figure 3 and Figure 4 As shown, the screening member 6 includes a limit frame 61, which is fixedly mounted on the upper end of the mounting frame 2, and a screening net 62 is slidably mounted on the inner surface of the limit frame 61, and both sides of the outer surface of the screening net 62 extend to the outside of the limit frame 61, and both sides of the outer surface of the screening net 62 extending to the outside of the limit frame 61 are provided with a linear reciprocating mechanism 63, and the linear reciprocating mechanism 63 is fixedly mounted on the upper part of the outer surface of the mounting box 1, and a transmission member 64 is provided on one side of the upper end of the limit frame 61, and the middle part of the outer surface of the transmission member 64 is connected to the output end of the transmission member 5 through a bevel gear set.

[0023] Further, such as Figure 5 As shown, the linear reciprocating mechanism 63 includes a limiting frame 631, which is fixedly mounted on the upper outer surface of the mounting box 1, a transmission disk 632 is provided in the middle of the inner cavity of the limiting frame 631, and a plurality of transmission blocks are provided on one side of the outer surface of the transmission disk 632, a slide plate 633 is provided in the middle of the inner cavity of the limiting frame 631, racks are provided on both the upper and lower sides of the inner surface of the slide plate 633, the transmission blocks and the racks are adapted for use, and one side of the outer surface of the slide plate 633 is fixedly connected to one side of the outer surface of the screening net 62 extending to the outside of the limit frame 61.

[0024] Specifically, when the motor 3 drives the primary crushing device 7 to operate through the transmission component 5, the transmission component 5 will also drive the linear reciprocating mechanisms 63 on both sides to operate through the transmission member 64, and then the linear reciprocating mechanism 63 drives the screening net 62 to perform linear reciprocating motion. In this process, the Chinese medicinal materials that are initially crushed by the primary crushing device 7 and fall on the upper part of the screening net 62 will be initially screened by the screening net 62. Only when the initially crushed Chinese medicinal materials are crushed to a certain size can they enter the next stage.

[0025] Furthermore, when the transmission member 64 drives the linear reciprocating mechanism 63 to operate through the belt, the transmission member 64 will first drive the transmission disk 632 to rotate. When the transmission disk 632 rotates, the multiple transmission blocks on the upper part of the transmission disk 632 will sequentially engage with the racks on the upper and lower sides of the inner surface of the slide plate 633, thereby causing the slide plate 633 to perform a linear reciprocating motion in the inner cavity of the limiting frame 631. During this process, the slide plate 633 drives the screening net 62 to perform a linear reciprocating motion, thereby accelerating the screening efficiency of the screening net 62.

[0026] Furthermore, the transmission member 64 is composed of a transmission rod, gears and belts, and is used to transfer the force transmitted by the transmission component 5 to the linear reciprocating mechanisms 63 on both sides to enable them to operate. This is a prior art and can be adjusted according to actual conditions, and will not be described in detail in this specification. Embodiment 2

[0027] This embodiment further improves the secondary crushing device 8 on the basis of the first embodiment, such as Figure 1 and Figure 2 As shown, a secondary crushing device 8 is provided at the upper part of the inner cavity of the mounting frame 2 .

[0028] After the primary pulverizing device 7 pulverizes the Chinese medicinal materials preliminarily, in order to pulverize the Chinese medicinal materials again to the required size, at the same time, in order to enable the pulverizing and grinding device to screen the pulverized medicinal materials according to the requirements of the pulverizing of the Chinese medicinal materials, such as Figure 6 As shown, the secondary crushing device 8 includes a circular frame 81, which is fixedly mounted on the upper part of the inner cavity of the mounting frame 2. A screening mechanism 83 is provided at the lower end of the circular frame 81, a crushing roller 82 is provided in the middle part of the inner cavity of the screening mechanism 83, a connecting mechanism 84 is provided on the side of the outer surface of the screening mechanism 83 away from the motor 3, and a control mechanism 85 is provided in the middle part of the outer surface of the connecting mechanism 84.

[0029] Furthermore, one side of the outer surface of the crushing roller 82 is connected to the output end of the motor 3 and the input end of the transmission component 5 via a belt.

[0030] Specifically, when the motor 3 drives the primary crushing device 7 and the screening element 6 to operate through the transmission component 5, the motor 3 will also drive the crushing roller 82 to rotate. When the Chinese medicinal materials preliminarily screened by the screening element 6 fall into the inner cavity of the screening mechanism 83, the crushing roller 82 in the inner cavity of the screening mechanism 83 will crush the preliminarily crushed Chinese medicinal materials again, thereby crushing the Chinese medicinal materials to the required size.

[0031] Furthermore, before the staff starts the motor 3 through the control component 4, it is necessary to adjust the screening mechanism 83 through the connecting mechanism 84 and the control mechanism 85 according to the final requirements of the Chinese medicinal materials crushing, and adjust the screening mechanism 83 to a state where only the Chinese medicinal materials particles crushed to a qualified size can pass through.

[0032] Further, in the present invention, the shape of the crushing roller 82 can be changed according to the crushing requirements, and it is not necessary to Figure 6 At the same time, the present invention is provided with two kinds of crushing components, namely, the primary crushing device 7 and the crushing roller 82, because some crushing rollers 82 have requirements on the size of the crushed objects.

[0033] In order to be able to screen the Chinese medicinal materials according to the requirements of Chinese medicinal materials crushing, such as Figure 7 and Figure 8 As shown, the screening mechanism 83 includes a placement frame 831, which is fixedly installed at the lower end of the circular frame 81. A plurality of screening plates 832 are arranged in the middle of the inner cavity of the placement frame 831. The outer surface array of the plurality of screening plates 832 is arranged with a plurality of groups of screening holes 833 and a plurality of limiting holes 834. The plurality of groups of screening holes 833 and the plurality of limiting holes 834 are distributed at intervals, and the screening holes 833 on the plurality of screening plates 832 gradually shrink from the inside to the outside.

[0034] Specifically, before crushing the Chinese medicinal materials, the staff can adjust the screening mechanism 83 through the control mechanism 85 and the connecting mechanism 84. During this process, since the screening holes 833 on the multiple screening plates 832 gradually shrink from the inside to the outside, when the staff needs to adjust the screening mechanism 83, they only need to pull all the screening plates 832 under the corresponding screening plates 832 that meet the requirements outward according to the needs, so that the limiting holes 834 on the pulled screening plates 832 are aligned with the screening holes 833 on the screening plates 832 that are not pulled. At this time, the adjustment of the screening mechanism 83 is completed. When the qualified Chinese medicinal material particles pass through the screening holes 833 on the corresponding screening plates 832, the Chinese medicinal material particles will pass through the limiting holes 834 on the pulled screening plates 832, and then the qualified Chinese medicinal material particles will be collected in the corresponding storage box.

[0035] Furthermore, in the process of adjusting the screening mechanism 83, filtering holes are also provided on the placement frame 831, such as Figure 8As shown, the filter holes are adapted for use with the multiple groups of sieve holes 833, and their diameters are larger than the diameters of the sieve holes 833 on the innermost sieve plate 832. Therefore, the placement frame 831 is also a layer of filter components and can be used as needed.

[0036] In order to control the screening mechanism 83, as Fig. 9 As shown, the connecting mechanism 84 includes a mounting cylinder 841, which is fixedly mounted on the outer surface of the mounting box 1. A plurality of connecting cylinders 842 are arranged on one side of the inner cavity of the mounting cylinder 841. The plurality of connecting cylinders 842 extend to the outside of the mounting cylinder 841 at one end close to the screening mechanism 83. The plurality of connecting cylinders 842 are sequentially sleeved together. The outer surfaces of the plurality of connecting cylinders 842 are provided with connecting holes on one side away from the screening mechanism 83. The outer surfaces of the plurality of connecting cylinders 842 are provided with connecting handles 843. The plurality of connecting handles 843 are respectively fixedly connected to one side of the outer surfaces of the plurality of screening plates 832.

[0037] Further, such as Fig. 9 and Fig.10 As shown, the control mechanism 85 includes a mounting ring 851 which is slidably mounted on the outer surface of the mounting tube 841 , a gear ring 852 is disposed on one side of the outer surface of the mounting ring 851 , and four positioning members 853 are disposed on the other side of the outer surface of the mounting ring 851 .

[0038] Further, such as Fig.10 — Fig.12 As shown, the positioning member 853 includes a screw 8531, the lower end of the screw 8531 extends to the interior of the mounting ring 851, and the lower end of the screw 8531 passes through the positioning hole 8411 and extends to the interior of the mounting tube 841, the screw 8531 is adapted for use with the connecting hole on the connecting tube 842, and two telescopic rods 8532 fixedly connected to the outer surface of the mounting ring 851 are provided on the upper portion of the outer surface of the screw 8531, and a gear 8533 is threadedly connected to the lower portion of the outer surface of the screw 8531, and the gear 8533 is rotatably installed on the upper portion of the outer surface of the mounting ring 851, and the gear 8533 is meshedly connected to the gear ring 852, and the telescopic rod 8532 is used here to limit the screw 8531.

[0039] Specifically, when the staff needs to adjust the screening mechanism 83, the staff can rotate the gear ring 852. When the gear ring 852 rotates, it drives the screw 8531 to move up and down through the gear 1 8533. The staff adjusts the position of the screw 8531 according to the required size of the Chinese medicinal material particles.

[0040] Furthermore, when the screw 8531 moves, the lower part of the screw 8531 enters the inner cavity of the connecting hole on the connecting tube 842 corresponding to the innermost sieve plate 832 to be pulled, and then the staff can pull the mounting ring 851 to move through the handle on the outer surface of the mounting ring 851, such as Fig. 9 As shown, when the mounting ring 851 moves, the mounting ring 851 will drive the four positioning members 853 to move, and then the screw rod 8531 will drive the multiple connecting cylinders 842 in contact with the outer surface of the screw rod 8531 to move, so that the pulled connecting cylinder 842 drives the corresponding screening plate 832 to move through the connecting handle 843 connected thereto, thereby completing the adjustment action of the screening mechanism 83.

[0041] It should be noted that the specific installation method, circuit arrangement and connection method of the motor 3 and the control component 4 used in the above-mentioned embodiment 1 and their control method are all conventional designs in the prior art and will not be elaborated in detail in the present invention.
