Description

Technical Field

[0001] The utility model relates to the technical field of velvet antler mushroom raw material screening, in particular to a multi-stage screening device for velvet antler mushroom raw materials. Background Art

[0002] Most existing velvet antler mushroom raw material screening devices use a single-level screen for screening, resulting in low screening efficiency and insufficiently refined grading. Furthermore, these screening processes often require frequent manual intervention, increasing worker workload and potentially introducing human error, impacting the quality consistency of the final product. Therefore, we proposed a multi-stage velvet antler mushroom raw material screening device. Utility Model Content

[0003] The main purpose of the utility model is to provide a multi-stage screening device for velvet antler mushroom raw materials, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A multi-stage screening device for velvet antler mushroom raw materials comprises a base, side support plates are fixedly mounted on both left and right sides of the upper end of the base, two chute grooves are formed at opposite ends of the two side support plates, a screening mechanism is slidably connected between the two side support plates via the chute, driving mechanisms are fixedly mounted on both left and right sides of the upper end of the base, and the two driving mechanisms are transmission-connected to the screening mechanism, three screening bodies are detachably mounted in the screening mechanism, and the three screening bodies are arranged at equal distances in the longitudinal direction;

[0006] The screening mechanism includes a fixed frame, and two slide bars used in conjunction with the slide groove are provided at the left and right ends of the fixed frame. A bottom plate is fixedly installed at the bottom of the fixed frame, and a protective plate is integrally formed at the lower front end of the fixed frame. The fixed frame is slidably connected to the side support plate through the slide bars on both sides.

[0007] Preferably, support rods are fixedly installed on the left and right sides of the upper end of the fixed frame, and fixed plates are fixedly installed on the left and right inner surfaces of the side support plates. The two support rods are slidably connected to the fixed plates on both sides respectively. The upper ends of the two support rods are fixedly installed with transmission wheels, and the lower ends of the transmission wheels are fixedly installed with return springs. The return springs are sleeved on the outside of the support rods and fixedly connected to the upper ends of the fixed plates. By adopting the above technical solution: when the eccentric wheel contacts the transmission wheel, the return spring is compressed and the screening mechanism moves downward. When the eccentric wheel separates from the transmission wheel, the return spring releases elastic potential energy, causing the screening mechanism to move upward, thereby causing the screening mechanism to vibrate back and forth up and down, achieving fast and efficient screening.

[0008] Preferably, the inner surface of the fixed frame is provided with three slots on both sides. The screening body is slidably mounted within the fixed frame via the two slots on the same horizontal plane. Three positioning blocks are fixedly mounted on the front and left sides of the fixed frame, with two positioning blocks forming a set and symmetrically distributed. This technical solution enables the simultaneous grading of velvet antler mushroom raw materials of varying particle sizes, thereby improving production efficiency.

[0009] Preferably, the screening body includes a filter plate, and the left and right ends of the filter plate are integrally formed with card strips used in conjunction with the card slots. A pull plate is fixedly installed at the front end of the filter plate, and pull slots used in conjunction with the positioning blocks are provided on the left and right sides of the front end of the pull plate. A positioning slot is provided in the middle of the front end of the pull plate, and a surrounding plate is fixedly installed on the upper end of the filter plate.

[0010] By adopting the above technical solution: the filter holes on the filter plate are set with different diameters to meet the screening requirements of raw materials of different sizes.

[0011] Preferably, the filter plate is slidably connected to the fixed frame through a clamping strip, and the pull groove is clamped with the positioning block to install the pull plate at the front end of the fixed frame.

[0012] By adopting the above technical solution, the screening body can be detachably installed, which is not only convenient for daily cleaning and maintenance, but also allows for quick replacement of filter plates of different specifications as needed to meet the screening requirements of raw materials of different sizes, and has a wide range of applications.

[0013] Preferably, the pores on the three filter plates decrease in size from top to bottom. By adopting the above technical solution, since the pores on the three filter plates decrease in size from top to bottom, larger particles remain on the top filter plate, while smaller particles pass through the finer filter plates. Ultimately, different sizes of velvet antler mushroom raw materials are collected in different screening bodies.

[0014] Preferably, the driving mechanism includes a stand, two of which are provided and fixedly mounted to the side support plates, a driving motor being fixedly mounted on the rear end of the rear stand, a rotating rod being fixedly mounted on the output end of the driving motor, the rotating rod being movably connected to the two stands, an eccentric wheel being fixedly mounted on the rotating rod, and the eccentric wheel being movably mounted between the two stands, and the mutual contact between the eccentric wheel and the transmission wheel connects the driving mechanism to the screening mechanism. By adopting the above technical solution: an automated screening process is realized through a simple mechanical structure, the labor intensity of workers is reduced, and the safety and convenience of operation are improved.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The automated screening process is realized through a simple mechanical structure, which reduces the labor intensity of workers and improves the safety and convenience of operation. At the same time, the multi-stage screening design can complete the grading of velvet antler mushroom raw materials of different particle sizes at one time, thereby improving production efficiency.

[0017] 2. The detachable installation of the screening body is achieved by sliding connection between the card strip and the card slot, and the card slot and the positioning block are connected. It is not only convenient for material removal and daily cleaning and maintenance, but also can quickly replace filter plates of different specifications according to needs to meet the screening requirements of raw materials of different sizes, and has a wide range of applications.

The present invention provides a technical solution:

[0025] A multi-stage screening device for velvet antler mushroom raw materials includes a base 1, side support plates 2 are fixedly installed on the left and right sides of the upper end of the base 1, two slide grooves 3 are opened at the opposite ends of the two side support plates 2, a screening mechanism 4 is slidably connected between the two side support plates 2 through the slide grooves 3, driving mechanisms 5 are fixedly installed on the left and right sides of the upper end of the base 1, and the two driving mechanisms 5 are transmission-connected to the screening mechanism 4, and three screening bodies 6 are detachably installed in the screening mechanism 4, and the three screening bodies 6 are arranged at equal distances in the longitudinal direction.

[0026] In this embodiment, the screening mechanism 4 includes a fixed frame 41, and two slide bars 42 for use with the slide groove 3 are provided at the left and right ends of the fixed frame 41. The bottom of the fixed frame 41 is fixedly installed with a bottom plate 43, and the front lower part of the fixed frame 41 is integrally formed with a protective plate 44. The fixed frame 41 is slidably connected to the side support plate 2 through the slide bars 42 on both sides; support rods 45 are fixedly installed on the left and right sides of the upper end of the fixed frame 41, and the left and right inner surfaces of the side support plate 2 are fixedly installed with fixed plates 7. The two support rods 45 are respectively slidably connected to the fixed plates 7 on both sides, and the upper ends of the two support rods 45 are fixedly installed with transmission wheels 46, and the lower ends of the transmission wheels 46 are fixedly installed with return springs 47. The return springs 47 are sleeved on the outside of the support rods 45 and fixedly connected to the upper ends of the fixed plates 7; the driving mechanism 5 includes a stand 51, and the stand 51 is provided with two and fixedly installed with the side support plate 2. The stand 51 at the rear A driving motor 52 is fixedly mounted on the rear end of the driving motor 52, and a rotating rod 53 is fixedly mounted on the output end of the driving motor 52. The rotating rod 53 is movably connected to the two vertical frames 51. An eccentric wheel 54 is fixedly mounted on the rotating rod 53, and the eccentric wheel 54 is movably mounted between the two vertical frames 51. The mutual contact between the eccentric wheel 54 and the transmission wheel 46 transmits the driving mechanism 5 to the screening mechanism 4.

[0027] According to the above scheme, the driving motor 52 drives the rotating rod 53 to rotate, and the eccentric wheel 54 on the rotating rod 53 rotates accordingly and periodically contacts the transmission wheel 46. When the eccentric wheel 54 contacts the transmission wheel 46, the return spring 47 is compressed, and the screening mechanism 4 moves downward. When the eccentric wheel 54 separates from the transmission wheel 46, the return spring 47 releases its elastic potential energy, causing the screening mechanism 4 to move upward, thereby causing the screening mechanism 4 to vibrate back and forth, driving the screening body 6 installed in the fixed frame 41 to vibrate back and forth, prompting the velvet antler mushroom raw materials to pass through the filter plates 61 with different apertures for classification, thereby realizing an automated screening process, reducing the labor intensity of workers, and improving the safety and convenience of operation.

[0028] In this embodiment, three card slots 411 are provided on the left and right sides of the inner surface of the fixed frame 41, and the screening body 6 is slidably installed in the fixed frame 41 through the two card slots 411 on the same horizontal plane. Three positioning blocks 412 are fixedly installed on the left and right sides of the front end of the fixed frame 41, and the two positioning blocks 412 are a group and are symmetrically distributed on the left and right sides; the screening body 6 includes a filter plate 61, and the left and right ends of the filter plate 61 are integrally formed with a card strip 62 for use with the card slot 411, and a pull plate 63 is fixedly installed at the front end of the filter plate 61, and a pull groove 631 for use with the positioning block 412 is provided on the left and right sides of the front end of the pull plate 63, and a positioning groove 632 is provided in the middle part of the front end of the pull plate 63, and a surrounding plate 64 is fixedly installed on the upper end of the filter plate 61; the filter plate 61 is slidably connected to the fixed frame 41 through the card strip 62, and the pull groove 631 is engaged with the positioning block 412 to install the pull plate 63 at the front end of the fixed frame 41; the three filter plates 61 The filter pores on the filter plates 61 decrease in size from top to bottom. Through the above scheme, since the filter pores on the three filter plates 61 decrease in size from top to bottom, larger particles remain on the topmost filter plate 61, while smaller particles pass through the finer filter plates 61. Ultimately, different sizes of velvet antler mushroom raw materials are collected in different screening bodies 6, respectively. This allows for the grading of velvet antler mushroom raw materials of different sizes to be completed in one go, improving production efficiency. Furthermore, the sliding connection between the clamping strip 62 and the clamping slot 411, and the engagement of the pull groove 631 with the positioning block 412, enable the detachable installation of the screening body 6. This not only facilitates material removal and daily cleaning and maintenance, but also allows for the rapid replacement of filter plates 61 of different specifications as needed to meet the screening requirements of raw materials of different sizes, thus providing a wide range of applications.It should be noted that the present invention is a multi-stage screening device for velvet antler mushroom raw materials. During use, the drive motor 52 is started, and the drive motor 52 drives the rotating rod 53 to rotate, and the eccentric wheel 54 on the rotating rod 53 rotates accordingly and periodically contacts the transmission wheel 46. When the eccentric wheel 54 contacts the transmission wheel 46, the return spring 47 is compressed, and the screening mechanism 4 moves downward. When the eccentric wheel 54 is separated from the transmission wheel 46, the return spring 47 releases elastic potential energy, causing the screening mechanism 4 to move upward, thereby causing the screening mechanism 4 to vibrate back and forth, driving the screening body 6 installed in the fixed frame 41 to vibrate back and forth, prompting the velvet antler mushroom raw materials to be graded through the filter plates 61 of different apertures, thereby realizing an automated screening process, reducing the labor intensity of workers, and improving the safety and convenience of operation. Since the filter hole sizes on the three filter plates 61 decrease from top to bottom, the larger particles remain on the top filter plate 61 On the other hand, smaller particles sequentially pass through finer filter plates 61. Ultimately, different sizes of velvet antler mushroom raw materials are collected in different screening bodies 6, enabling the grading of velvet antler mushroom raw materials of different sizes to be completed in one go, improving production efficiency. Finally, the filter plate 61 is pulled out of the fixed frame 41 via the positioning slot 632, allowing the raw materials collected in the screening body 6 to be taken out, making material removal convenient. At the same time, the sliding connection between the clamping strip 62 and the clamping slot 411 and the engagement of the pull groove 631 with the positioning block 412 ensure a secure installation of the screening body 6 and the fixed frame 41. This not only facilitates daily cleaning and maintenance, but also allows for the rapid replacement of filter plates 61 of different specifications as needed to meet the screening requirements of raw materials of different sizes, thus providing a wide range of applications.
