[0001] The utility model relates to the field of preparation of edible and medicinal mushroom culture media, and particularly to a leather sleeve screening mechanism for fixing a culture medium basin with a film. Background Art

[0002] Cordyceps flower, also known as Cordyceps militaris and Cordyceps pupa, has certain similarities in composition with Cordyceps sinensis. Cordyceps flower, together with ginseng and pilose antler, is listed as the three major tonics in China. And as a precious edible and medicinal mushroom, under the background of the rapid development of modern agricultural technology, the optimization of its production process has always been a hot topic in the industry research.

[0003] The production process of Cordyceps flower includes the preparation of cultivated species → preparation of culture medium → sterilization and inoculation → shelf cultivation for mycelium growth → fruiting body management → harvesting → storage. In the prior art, the production and preparation of Cordyceps flower culture medium mainly rely on the combination of manual labor and labor tools. After the injection process of solid materials and liquid materials in the culture medium basin is completed, the subsequent process requires covering the film to seal the culture medium basin, and then the processes such as "sterilization and inoculation" can be carried out.

[0004] However, after the injection process of the Cordyceps flower culture medium basin is completed, considering the requirements of subsequent process operations, it only needs to use a leather sleeve to cover and fix the film at the opening end of the culture medium basin. In the prior art, this process is mainly completed manually, with high labor intensity and low production efficiency. Among them, the leather sleeves need to be manually screened and separated one by one and then sleeved on the basins, which further increases the labor intensity. Summary of the Utility Model

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown, the utility model comprises a bracket 3, a motor 1, a transmission assembly 5 and a screw 2, wherein a plurality of screws 2 are rotatably arranged on the bracket 3, and as shown in Figure 2 As shown, the screw rod 2 is provided with a spiral protrusion 206, and the leather cover 4 is sleeved on the spiral protrusion 206 of each screw rod 2, and the leather cover 4 is stretched and tensioned by each screw rod 2, and each screw rod 2 is driven by the motor 1 to rotate synchronously, and the motor 1 transmits torque through the transmission assembly 5 arranged on the lower side of the bracket 3, and the upper end of the screw rod 2 is provided with a slot 201. When the utility model is working, when each screw rod 2 rotates synchronously, the spiral protrusion 206 on each screw rod 2 also rotates. Since the leather cover is tensioned by the spiral protrusion 206 on each screw rod 2, as shown in FIG. Figure 2 As shown, the part of the leather cover 4 sleeved on the corresponding screw rod 2 will move along the spiral protrusion 206 to achieve lifting and lowering as the spiral protrusion 206 on the screw rod 2 rotates, wherein the upper end of the spiral protrusion 206 is connected with the slot 201 at the upper end of the corresponding screw rod 2, and when the leather cover rises to the upper end of the screw rod 2, the uppermost leather cover 4 will be separated from the spiral protrusion 206 and elastically retracted to be stuck in the slot 201 at the upper end of each screw rod 2, so that it can no longer move along the spiral protrusion 206, and then the motor 1 controls each screw rod 2 to move in the opposite direction to make the remaining leather covers all descend, so that a sufficient distance is generated between the leather cover 4 stuck in the slot 201 and the remaining leather covers, and then the leather cover removal device moves to the top of the utility model and removes the leather cover 4 stuck in the slot 201, as shown in FIG. Figure 6 As shown, in this embodiment, the holster removing device is provided with a plurality of expandable and closable holster struts 6. When removing the holster 4, each holster strut 6 is first contracted horizontally, and then the holster removing device is lowered so that the contracted holster struts 6 are inserted into the uppermost holster 4 stuck in the card slot 201, and after the holster removing device is lowered into place, the lower ends of each holster strut 6 are located above the other holsters, so that when each holster strut 6 is reopened, the uppermost holster 4 can be propped open to make it detach from the card slot 201 and each screw rod 2, and at the same time, other holsters will not be affected, and then the holster removing device rises and drives the holster 4 tightened at the lower end to move to the corresponding work station.

[0024] As Figure 2 shown, in this embodiment, a pressure sensor 202 is provided at the upper end of the screw 2, and the trigger end on the lower side of the pressure sensor 202 is connected to the upper end of the screw 2. In this way, a card slot 201 is formed between the lower surface of the pressure sensor 202 and the upper end surface of the screw 2. When the outermost leather sleeve 4 elastically shrinks into the card slot 201, the pressure sensor 202 is triggered, that is, the trigger end of the pressure sensor 202 senses a pressure change. At this time, the pressure sensor 202 sends a signal to the control system, and the control system automatically controls the motor 1 to reverse. The pressure sensor 202 is a commercially available product. For example, a pressure sensor of Omron brand can be purchased.

[0025] As Figures 4 to 5 shown, in this embodiment, the transmission assembly 5 includes a synchronous belt 501 and a plurality of tension wheels. A driving pulley 101 is provided on the motor shaft of the motor 1, and a screw pulley is provided at the lower end of each screw 2. The synchronous belt 501 bypasses the driving pulley 101, each tension wheel and each screw pulley. Among them, as Figure 5 shown, in this embodiment, a first tension wheel 502 is provided on one side of the first screw pulley 204 close to the driving pulley 101, and a second tension wheel 503 is provided on the other side. The synchronous belt 501 bypassing the driving pulley 101, the first screw pulley 204, the first tension wheel 502 and the second tension wheel 503 forms a cross shape. A third tension wheel 504 is provided on one side of the second screw pulley 205 far from the driving pulley 101, and the synchronous belt 501 bypassing the third tension wheel 504 and the second screw pulley 205 forms a T shape.

[0026] As Figure 1 and Figure 4 shown, in this embodiment, a screw base 203 is provided on the bracket 3, and the lower end of the screw 2 is rotatably installed in the corresponding screw base 203 through bearing support.

[0027] The working principle of the present utility model is as follows:

[0028] When the present utility model works, it needs to cooperate with the operation of the leather sleeve taking device. The leather sleeve taking device is a well-known technology in the art. As Figure 6As shown in the figure, it is provided with a plurality of expandable and collapsible leather sleeve struts 6. When the present utility model works, when each screw rod 2 rotates synchronously, the spiral convex portions 206 on each screw rod 2 also rotate accordingly. The portion of the leather sleeve 4 sleeved on the corresponding screw rod 2 moves along the spiral convex portion 206 with the rotation of the spiral convex portion 206 on the screw rod 2 to achieve lifting and lowering. When the leather sleeve rises to the upper end of the screw rod 2, the uppermost leather sleeve 4 will disengage from the spiral convex portion 206 and elastically retract and be stuck in the card slots 201 at the upper ends of each screw rod 2. Then, the motor 1 controls each screw rod 2 to move in the reverse direction so that the remaining leather sleeves all descend. In this way, a sufficient distance is generated between the leather sleeve 4 stuck in the card slot 201 and the remaining leather sleeves, thereby realizing the single separation and screening of the leather sleeves. Then, the leather sleeve taking device moves above the present utility model. When taking the leather sleeve 4, each leather sleeve strut 6 first contracts horizontally with its diameter reduced. Then, the leather sleeve taking device descends so that the leather sleeve strut 6 with its diameter reduced after contraction is inserted into the uppermost leather sleeve 4 stuck in the card slot 201. And after the leather sleeve taking device descends in place, the lower ends of each leather sleeve strut 6 are all located above the other leather sleeves. In this way, when each leather sleeve strut 6 expands again, it can expand the uppermost leather sleeve 4 to make it disengage from the card slot 201 and each screw rod 2, and at the same time, it will not affect the other leather sleeves. Then, the leather sleeve taking device rises and drives the leather sleeve 4 tightly supported at the lower end to move to other workstations.

[0029] As Figure 6 shown, the overall structure of the present utility model is simple and convenient to control, can be integrated into an automated production line for culture media such as Cordyceps militaris, and can meet the use requirements of the automated production line for culture media.
