Technical Field

[0001] The invention relates to an automatic tearing device for a protective cover of bottle-grown mushrooms, belonging to the technical field of agricultural automated production. Background Art

[0002] Flammulina velutipes is the main cultivated variety of edible fungi in my country. It is delicious, nutritious, and has a variety of pharmacological effects, which is deeply loved by people. Flammulina velutipes is mainly supplied to the market as fresh goods. With the development of cultivation technology, the cultivation of Flammulina velutipes has gradually appeared in factory production, which not only improves the output and quality, but also breaks the seasonal restrictions and realizes year-round production, especially changing the consumption and demand in the summer market. At present, large-scale factories of Flammulina velutipes basically adopt bottle cultivation technology. Compared with bag cultivation, bottle cultivation has the advantages of anti-pollution, short growth period, high quality, and low labor cost. After the strain is inoculated in the culture bottle, the culture bottle needs to be placed in a greenhouse for cultivation. In order to ensure the growth environment and conditions of Flammulina velutipes, the opening of the culture bottle is usually surrounded by mushroom slices to provide the required growth environment for Flammulina velutipes through the shaping cavity formed by the mushroom slices and complete the shaping of Flammulina velutipes. However, when the Flammulina velutipes are taken out of the culture bottle after maturity, the mushroom slices need to be torn open before the Flammulina velutipes can be taken out. At present, large-scale factories producing Flammulina enoki mushrooms basically adopt the method of manual slicing, which is not only labor-intensive and inefficient, but also has the risk of workers damaging the mushroom caps due to careless operation, thus reducing the quality of the mushrooms.

[0047] Working principle of the present invention:

[0048] See also Figure 1-10When the automatic sleeve tearing device is working, first in the feeding area, the culture bottle 11 is held by the bottle holding claw 5 after the front ends of the two claws 52 are opened. Then, as the tearing disc 2 rotates, the outer peripheral surface of the bottle holding guide rail 63 contacts the cam bearing 55 at the rear end of the claw 52, ​​and the rear ends of the two claws 52 on the same bottle holding claw 5 are opened so that the front end of the bottle holding claw 5 can better hold the culture bottle 11, preventing the culture bottle 11 from falling out. Then, the outer peripheral surface of the driving guide rail 62 contacts the driving rubber wheel 42 at the lower end of the tearing guide assembly 4, and the driving rubber wheel 42 rotates and drives the tearing rubber wheel 41 to rotate through the connecting shaft 43, thereby driving the culture bottle 11 that is tightly attached to the tearing rubber wheel 41 to rotate.

Through the guidance and hooking of the hook of the outer guide plate 31, the originally rolled mushroom slice 12 is torn from the adhesive position and enters the clamping portion between the inner guide plate 32 and the outer guide plate 31. Through the continued rotation of the tearing rubber wheel 41 and the notch 33 opened in the hook of the inner guide plate 32, the mushroom slice 12 is temporarily clamped in the clamping portion. The tearing disc 2 continues to rotate, the driving guide rail 62 is separated from the driving rubber wheel 42, and the tearing rubber wheel 41 stops rotating. Then in the discharge area, the bottle holding guide rail 63 is separated from the cam bearing 55 at the rear end of the claw 52, ​​and the front end of the claw 52 can move freely, the inner side of the culture bottle 11 contacts the front end of the bottle discharge track 64, and the culture bottle 11 can be disengaged from the bottle holding claw 5 along the bottle discharge track 64. The claw 52 on the bottle holding claw 5 is reset by the elastic force of the tension spring 56. The tearing disc 2 continues to rotate, and the inner circumference of the ejecting guide rail 65 contacts the driving rubber wheel 42. The driving rubber wheel 42 rotates to drive the tearing rubber wheel 41 to reverse, and the mushroom piece 12 originally engaged in the clamping piece is brought out of the clamping piece, thereby realizing the ejection of the mushroom piece 12.

[0049] Embodiment 2:

[0050] As another embodiment of the present invention, the difference between this embodiment and the first embodiment is that the automatic sleeve tearing fixture of the first embodiment is used on the tearing disc 2 that adopts a circular cycle travel mode.

A linear slide rail 73 is fixed on the fixed seat 7, and a slider 72 that can slide freely on the slide rail 73 is fixed at the lower end of the bracket 71. A cylinder 74 is also fixed on the fixed seat 7, and a piston rod of the cylinder 74 is fixed to the bracket 71, so that when the piston rod of the cylinder 74 reciprocates, it can drive the bracket 71 to reciprocate along the slide rail 73 on the fixed seat 7.

[0052] The tearing sleeve clamp includes a tearing sheet guide plate group 3, a tearing sheet guide assembly 4, a bottle holding claw 5, and a culture bottle 11. The structures of the tearing sheet guide plate group 3, the tearing sheet guide assembly 4, the bottle holding claw 5, and the culture bottle 11 are still the same as those in the first embodiment.

In particular, to ensure that the tear sheet guide assembly 4 can drive the culture bottle 11 to rotate, a driven rubber wheel 75 can be additionally fixed in the middle of the connecting shaft 43. The outer peripheral surface of the driven rubber wheel 75 can be attached to the outer peripheral surface of the culture bottle 11, and rotate when the connecting shaft 43 rotates, driving the culture bottle 11 to rotate, thereby enhancing the rotation effect of the culture bottle 11.

[0053] Correspondingly, the guide rails of this embodiment include a driving guide rail 62 and a bottle holding guide rail 63, both of which are linear, and the driving guide rail 62 and the bottle holding guide rail 63 are arranged in parallel with the slide rail 73. The driving guide rail 62 is fixed on the fixing seat 7, and the bottle holding guide rail 63 is fixed at the middle of the upper end of the driving guide rail 62, and the length of the bottle holding guide rail 63 should be smaller than the driving guide rail 62. Among them, the outer peripheral surface of the driving guide rail 62 can contact with the lower end of the driving rubber wheel 42 and drive the tearing rubber wheel 41 to rotate, and the bottle holding guide rail 63 can contact with the cam bearing 55 arranged at the rear end of the claw 52.

[0054] The working principle of this embodiment:

[0055] See also Figure 11-12When the automatic sleeve tearing fixture is working, first, the piston rod of the cylinder 74 is in a retracted state, and the bracket 71 is close to the cylinder 74. At this time, the culture bottle 11 can be placed on the bottle holding claw 5. Then, the cylinder 74 is driven to extend the piston rod, and the bracket 71 moves linearly along the slide rail 73. The cam bearing 55 at the rear end of the claw 52 contacts the bottle holding guide rail 63, and the rear ends of the two claws 52 on the bottle holding claw 5 are stretched open, so that the front end of the bottle holding claw 5 can better hold the culture bottle 11, preventing the culture bottle 11 from falling out. Then, the bracket 71 continues to move, the driving rubber wheel 42 contacts the driving guide rail 62, the driving rubber wheel 42 rotates and drives the tearing rubber wheel 41 (and the driven rubber wheel 75) to rotate through the connecting shaft 43, thereby driving the culture bottle 11 to rotate. As the culture bottle 11 rotates, the adhesive edge of the mushroom piece 12 sleeved on the upper end of the culture bottle 11 will be guided to the tearing guide plate group 3, and through the guidance and hooking of the hook part of the outer guide plate 31, the originally cylindrical mushroom piece 12 is torn from the adhesive position and enters the clamping part between the inner guide plate 32 and the outer guide plate 31, and through the continued rotation of the tearing rubber wheel 41 and the notch 33 provided in the hook part of the inner guide plate 32, the mushroom piece 12 is temporarily clamped in the clamping part, completing the tearing work. Then, the driving cylinder 74 retracts the piston rod, the driving rubber wheel 42 contacts the driving guide rail 62, the driving rubber wheel 42 rotates to drive the tearing rubber wheel 41 to reverse, and the mushroom piece 12 originally engaged in the clamping piece is brought out of the clamping piece, so as to realize the withdrawal of the mushroom piece 12. Then, the bracket 71 continues to move, the cam bearing 55 at the rear end of the claw 52 separates from the bottle holding guide rail 63, and when the bracket 71 is close to the cylinder 74, the culture bottle 11 can be taken out, and the culture bottle 11 to be torn can be placed, and this can be repeated.
