Technical Field

[0001] The utility model belongs to the technical field related to ginkgo leaf processing, and particularly relates to a ginkgo leaf crushing device. Background Art

[0002] The dried leaves of Ginkgo biloba have medicinal value. Ginkgo biloba extract is a kind of product that uses Ginkgo biloba as raw material and appropriate solvents to extract the effective ingredients. When extracting Ginkgo biloba extract, the dried Ginkgo biloba leaves are usually crushed into pieces to improve the quality and efficiency of the extraction.

[0003] In the prior art, when the dried ginkgo leaves are crushed, a relatively single crushing knife is used for crushing. Since the dried ginkgo leaves are relatively light, the crushing efficiency is not high in a larger crushing chamber. During the crushing operation, the leaves are likely to float above the crushing operation interval, which can easily lead to uneven crushing and low crushing efficiency. In addition, the completely and incompletely crushed leaves are not screened out in time, which also affects the crushing efficiency. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a ginkgo leaf crushing device, which can limit the size of the crushing space, perform crushing operations at different heights, and can perform variable crushing and side screening after crushing to a certain extent, thereby improving the crushing efficiency.

[0005] The technical solution adopted by the utility model is as follows: a ginkgo leaf crushing device, including a frame, a crushing barrel and a lifting crushing assembly; the frame has a corresponding supporting force; the crushing barrel is fixed on the frame, has a corresponding accommodating chamber inside, and forms a discharge channel at the bottom; a vibrating screen is arranged in the lower part of the accommodating chamber; the lifting crushing assembly includes a lifting support unit, which is erected above the crushing barrel, and the telescopic part can move in and out of the crushing barrel along the central axis direction of the crushing barrel, and the telescopic part of the lifting support unit is connected to the mounting frame for placing and supporting the rotating drive; the crushing unit is located at the bottom of the mounting frame, connected to the rotating drive, and performs corresponding crushing operations at a corresponding height in the crushing chamber.

[0006] Furthermore, the crushing unit includes a supporting shaft fixedly connected to the rotary drive output end; a crushing knife assembled at the bottom end of the supporting shaft; a cover plate fixed on the supporting shaft and located above the crushing knife, having corresponding supporting force, and a crushing space is formed between the cover plate and the vibrating screen; a vibration ring fixed to the bottom of the cover plate by an elastic telescopic rod and located outside the rotation track of the crushing knife.

[0007] Furthermore, grinding protrusions are provided at the bottom of the vibration ring, and the grinding protrusions are arranged in a ring array.

[0008] Furthermore, the outer diameter of the cover plate matches the inner diameter of the accommodating chamber of the grinding cylinder, and the accommodating chamber is closed at different heights.

[0009] Furthermore, the lifting support unit is a lifting column connected to a hydraulic working system to perform corresponding lifting operations, and the lifting column is erected above the crushing cylinder through a support frame.

[0010] After adopting the above structure, the beneficial effects of the utility model are as follows: the ginkgo leaf crushing device proposed by the utility model, by setting a cover plate at a predetermined position above the crushing knife, rises and falls synchronously with the crushing assembly, limits the upper limit of the crushing space at different heights, prevents the leaves from floating up and leaving the crushing operation space, and improves the uniformity and efficiency of crushing;

[0011] By means of a vibration ring arranged outside the rotating track of the crushing knife and a grinding protrusion arranged at the bottom of the vibration ring, when the crushing knife approaches the vibration screen, it cooperates with the vibration screen to grind and crush the blades located at the edge, and when vibrating, the vibration screen is accelerated to screen and discharge the crushed material during the crushing process, thereby reducing the burden of the tool crushing and improving the crushing efficiency.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0019] like Figure 1-3 As shown, a ginkgo leaf crushing device comprises a frame 1, a crushing barrel 2 and a lifting crushing assembly; the frame 1 has a corresponding supporting force; the crushing barrel 2 is fixed on the frame 1, and has a corresponding accommodating chamber inside, and a discharge channel 3 is formed at the bottom; here, preferably, the frame 1 is L-shaped as a whole, a fixing block is arranged on the inner side of the vertical side wall, and the installation working surface of the fixing block forms two fixing rings spaced up and down, and the crushing barrel 2 can be cylindrical and fixed by two fixing rings, so that the crushing barrel 2 is stably mounted on the frame 1; a vibrating screen 4 is arranged in the lower part of the accommodating chamber; a vibrating block is arranged inside the vibrating screen 4, and the inner diameter of the screen hole is set to a certain size, so that the crushed leaf fragments that meet the size are discharged to the discharge channel 3. The lifting crushing assembly lifts and lowers the crushing functional component above the vibrating screen 4, and performs corresponding crushing operations at different heights. During the crushing process, the vibrating screen 4 vibrates, accelerating the fragments that meet the size to pass through the screen hole into the discharge channel 3, thereby reducing the operating pressure of the crushing functional component.

[0020] In some preferred embodiments, the lifting and crushing assembly includes a lifting support unit and a crushing unit. The lifting support unit is mounted above the crushing barrel 2, and the telescopic part can enter and exit the crushing barrel 2 along the central axis direction of the crushing barrel 2, and the telescopic part of the lifting support unit is connected to the mounting frame 5, which is used to place the support rotation drive 6. Specifically, the lifting support unit is a lifting column 12, which is connected to the hydraulic working system for corresponding lifting operations. The lifting column 12 is mounted above the crushing barrel 2 through the support frame; the crushing unit is located at the bottom of the mounting frame 5, connected to the rotation drive 6, and performs corresponding crushing operations at a corresponding height in the crushing, wherein the outer diameter of the cover plate 9 of the crushing unit matches the inner diameter of the accommodating chamber of the crushing barrel 2, and the accommodating chamber is closed at different heights with the lifting support unit, changing the size of the crushing space formed between the cover plate 9 and the vibrating screen 4, and closing the crushing space at the upper end to prevent the blades from being brought up and out of the crushing space during crushing.

[0021] In some preferred embodiments, the crushing unit includes a supporting shaft 7, which is fixedly connected to the output end of the rotary drive 6; a crushing knife 8, which is assembled at the bottom end of the supporting shaft 7; a cover plate 9, which is fixed on the supporting shaft 7 and located above the crushing knife 8, has corresponding supporting force, and a crushing space is formed between the cover plate 9 and the vibrating screen 4; a vibrating ring 10, which is fixed to the bottom of the cover plate 9 by an elastic telescopic rod and is located outside the rotation track of the crushing knife 8. A grinding protrusion 11 is arranged at the bottom of the vibrating ring 10, and the grinding protrusion 11 is arranged in a circular array. When the vibrating ring 10 vibrates, it is misaligned with the vibrating screen 4. The grinding protrusion 11 further crushes the blades located at the edge of the vibrating screen 4, thereby reducing the dead angle of crushing and improving the uniformity of crushing.

[0022] It should be noted that the elastic telescopic rod includes an outer sleeve 13 and a sliding rod 14. A support spring is arranged inside the outer sleeve 13. One end of the sliding rod 14 is located inside the outer sleeve 13 and the other end extends out of the outer sleeve 13 along the central axis direction of the outer sleeve 13. The sliding rod 14 is slidably connected to the outer sleeve 13, and one end located inside the outer sleeve 13 is connected to the support spring. The sliding rod 14 squeezes the support spring and slides into the outer sleeve 13. After the external force is withdrawn, the sliding rod 14 can be reset under the reverse force of the support spring.

[0023] When in use, the device is placed in a suitable working position; in the initial state, the cover plate 9 is located above the crushing cylinder 2, the opening above the crushing cylinder 2 is opened, and the material is fed from the opening, and the dry ginkgo leaves that need to be crushed are put in; the lifting column 12 controls the cover plate 9 and the crushing unit to descend to a suitable position in the crushing cylinder 2, and the rotary drive 6 is started. The output end of the rotary drive 6 rotates to drive the supporting shaft 7 to rotate, and the supporting shaft 7 rotates to drive the crushing knife 8 to perform crushing operations at a corresponding height position; or in the initial crushing, the cover plate 9 is pressed down to squeeze and crush the dry leaves, the elastic telescopic rod at the bottom of the cover plate 9 is squeezed, and the grinding protrusion 11 at the bottom of the vibration ring 10 is against the vibration. On the screen 4, the blades are squeezed into the smaller crushing space between the cover plate 9 and the vibrating screen 4; after starting the rotary drive 6, the crushing knife 8 rotates in the crushing space to crush the blades. At this time, the cover plate 9 and the vibration ring 10 under the cover plate 9 rotate with the supporting shaft 7, and the vibration ring 10 and the vibrating screen 4 both vibrate (a vibration block is set inside the skeleton, and when the vibration block is started, the vibration ring 10 and the vibrating screen 4 vibrate). The grinding protrusion 11 grinds and crushes the blades at the edge of the vibrating screen 4, reducing the crushing dead angle of the crushing knife 8. The blades are confined to the space between the cover plate 9 and the vibrating screen 4 for crushing, avoiding the blades from floating out of the crushing operation range, thereby improving the crushing efficiency.

[0024] In addition, it should be noted that during the crushing process, the crushed material on the vibrating screen 4 can be discharged into the discharge channel 3 through the screen holes, and the crushed material in the crushing space is continuously reduced during the crushing process, thereby reducing the crushing burden of the crushing knife 8.

[0025] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the scope of protection of the utility model.
