[0002] Chinese medicinal materials are mostly divided into rhizomes, fruits and seeds in terms of their shapes. In actual use, in order to fully exert the medicinal properties of seed-based medicinal materials, the seed shells need to be removed and the seeds inside taken out. Currently, the common methods mostly use manual pounding or heavy crushing. However, the former has the problems of low threshing efficiency, high labor costs and difficult quality control, while the latter has the problem of easily crushing the seeds completely and being difficult to adjust, which is not conducive to threshing needs. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1: Figure 1-4 As shown, an automatic threshing device for Chinese medicinal materials comprises a processing bucket and a control panel, wherein a threshing mechanism is arranged in the processing bucket;

[0025] The threshing mechanism comprises a fixed suspension 1, a transmission assembly and a crushing shell 2, wherein the fixed suspension 1 is arranged at the upper end of the processing bucket, the transmission assembly is connected to the middle part of the fixed suspension 1 and extends into the processing bucket, and the crushing shell 2 is located in the processing bucket and is transmission-connected to the transmission assembly;

[0026] The crushing shell 2 has a diamond-shaped structure, and the processing bucket is composed of an upper bucket 3 and a lower bucket 31 which are integrally formed and distributed up and down. The processing bucket has a funnel-shaped structure as a whole, and the inner diameter of the processing bucket gradually decreases from top to bottom. Grinding strips are provided on the lower side of the crushing shell 2 and the inner wall of the lower bucket 31.

[0027] When the medicinal materials are threshed, the transmission assembly is controlled by the control panel to drive the broken shell 2 to adjust its upper and lower positions in the processing bucket, so that the broken shell 2 and the inner wall of the lower bucket 31 retain a distance suitable for the volume of the medicinal materials, wherein the interval between the lower bucket 31 and the broken shell 2 gradually decreases from top to bottom, so that the medicinal materials can be effectively broken by the gradually reduced interval after entering the processing bucket and falling into the gap between the broken shell 2 and the processing bucket;

[0028] When threshing and shelling, the shell of the medicinal material can be broken and the seed part inside can be retained by reducing the interval between the shell 2 and the lower bucket 31 and cooperating with the grinding strips, and finally the seeds and shells are discharged together through the discharge port on the lower side of the lower bucket 31;

[0029] When the medicinal materials are processed, the control panel can be used to control the transmission assembly to drive the crushing shell 2 to move the threshing lower bucket 31 upward, so that the inner walls of the crushing shell 2 and the lower bucket 31 are completely exposed for easy cleaning. At the same time, in some cases, if some medicinal materials are stuck between the lower bucket 31 and the crushing shell 2, they can be cleaned and removed conveniently and quickly.

[0030] The transmission assembly includes a hydraulic cylinder 4, a lower support frame 41, a motor 42 and an extension shaft 43. The hydraulic cylinder 4 is fixedly arranged at the upper end of the fixed suspension 1, the motor 42 is located at the lower side of the fixed suspension 1 and is connected to the output shaft of the hydraulic cylinder 4, the lower support frame 41 is connected to the lower end of the fixed suspension 1 and carries the motor 42, the extension shaft 43 is rotatably connected to the lower end of the lower support frame 41 and is transmission-connected to the output shaft of the motor 42, and the other end of the extension shaft 43 is concentrically connected to the upper end of the broken shell 2.

[0031] The hydraulic cylinder 4 is used to connect and adjust the motor 42, and finally drives the crushing shell 2 to adjust the height position through the extension shaft 43. The setting of the lower support frame 41 can further support the components. The motor 42 cooperates with the extension shaft 43 to drive the crushing shell 2 to rotate to produce the shell breaking effect.

[0032] A protective cover is also provided on the upper end of the processing bucket; during processing, the opening on the upper side of the processing bucket can be shielded to prevent impurities from splashing out.

[0033] Example 2: Figure 1-3 As shown, a further improvement on the basis of Example 1 is provided between the extension shaft 43 and the fixed suspension 1. The number of the pushing assemblies is two and they are symmetrically distributed. The pushing assembly comprises a vertical guide rod 5, a transverse support frame 51, a mosaic bead and a pressure ring 52. The vertical guide rod 5 is connected to the fixed suspension 1 for sliding up and down movement through a guide rib. The transverse support frame 51 is connected to the lower end of the vertical guide rod 5 and is parallel to the ground. A guide groove 53 is provided on the side of the extension shaft 43. The mosaic bead is connected to the end of the transverse support frame 51 and extends into the guide groove 53. The pressure ring 52 is connected to the lower end of the transverse support frame 51 and matches the gap position between the upper bucket 3 and the broken shell 2.

[0034] The guide groove 53 is connected end to end, and the plane unfolding trajectory of the guide groove 53 is a sine wave line trajectory.

[0035] Furthermore, in order to prevent some medicinal materials from falling exactly between the upper bucket 3 and the crushing shell 2, during the process of the extension shaft 43 driving the crushing shell 2 to rotate, the position of the guide groove 53 on the side of the extension shaft 43 changes in real time, thereby guiding the embedded beads of the transverse support frame 51 embedded in the groove. Since the trajectory of the guide groove 53 is a sine wave structure, it will guide the transverse support frame 51 to produce a cyclic change in the up and down position, and then use the pressure ring 52 to press down the medicinal materials in the interval, thereby promoting the smoothness and efficiency of the feeding of the medicinal materials and reducing the jamming. The setting of the vertical guide rod 5 can stabilize the transverse support frame 51 and the pressure ring 52, and the upper end of the vertical guide rod 5 is also provided with a limit plate to prevent the vertical guide rod 5 from being disconnected from the fixed suspension 1.

[0036] Example 3: Figure 1-4 As shown, based on the further improvement of Example 1, a primary screening assembly is further provided at the lower end of the lower bucket 31, and the primary screening assembly includes a sieve plate 6, a vibrator and a telescopic connecting rod 61. The number of the telescopic connecting rods 61 is several and they are evenly arranged on the upper end of the sieve plate 6. The telescopic connecting rod 61 is fixedly connected to an external fixed object, one end of the vibrator is connected to the lower end of the broken shell body 2 and the other end passes through the sieve plate 6 and abuts against it.

[0037] The vibrator comprises a connecting rod 62 , a push plate 63 and a fixed plate 64 . One end of the connecting rod 62 slides through the crushing shell 2 and is connected to the push plate 63 . The fixed plate 64 is connected to the lower end of the sieve plate 6 and abuts against the push plate 63 .

[0038] A plurality of lifting bodies 65 are evenly arranged on the upper end of the push plate 63 , with intervals between adjacent lifting bodies 65 . The lifting bodies 65 are in an isosceles trapezoidal structure as a whole. A vibration block 66 matching the lifting bodies 65 is arranged on the lower end of the fixed plate 64 .

[0039] In order to further reduce the difficulty of subsequent screening and meet the needs of screening by air selection equipment, after the medicinal materials are threshed, the primary screening component can be used to remove smaller debris, powder impurities, etc. in advance, so that impurities, debris, etc. will not be selected together when the medicinal materials seeds are subsequently air-selected. After the medicinal materials are threshed, the seeds, debris and shells will fall into the sieve plate 6 at the same time, wherein the sieve plate 6 is connected to the outside through a telescopic connecting rod 61, and during the rotation of the crushing shell 2, the push plate 63 will be synchronously driven to rotate. At this time, the lifting body 65 at the upper end of the push plate 63 will abut against the vibration block 66 at the lower end of the fixed plate 64, so that the sieve plate 6 produces an up and down reciprocating motion, and the screening is promoted by the abutment vibration between the components. Furthermore, the lifting body 65 can also be a right-angled triangle structure, so that after the sieve plate 6 is lifted by the lifting body 65, the resetting of the telescopic connecting rod 61 produces a stronger vibration effect to achieve the screening requirements.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
