Description

TECHNICAL FIELD

[0001] The present application relates to the field of edible fungi, and in particular to a mushroom cultivation opening device. BACKGROUND

[0002] The existing patent (publication number: CN111990174A) proposes a culture bag punching device for mushroom cultivation, in which "two groups of rotating plates are arranged to abut against the outer surface of the mushroom bag, and cooperate with the first clamping motor and the fixed rod to make the mushroom bag rotate 360 degrees, so that the reciprocating punching column punches the mushroom bag, thereby ensuring the uniformity of the punching on the outer surface of the mushroom bag", however, the punching during rotation is prone to uneven punching and damage due to excessive local hardness in the mushroom bag, reducing the opening quality and efficiency.

[0003] In addition, even if the existing opening device with other structures adopts a circumferential arrangement, the opening wheel is prone to misalignment or shifting during rotation, causing the mushroom bag to be unevenly opened in a triangular shape, which needs to be improved. SUMMARY

[0004] The present application aims to solve the above problems in the prior art, and provides a mushroom cultivation opening device that automatically completes mushroom bag punching, reduces mushroom bag jamming, damage and twisting, and improves the opening quality and efficiency of the mushroom bag.

[0005] The purpose of the present application is achieved by the following technical solutions:

[0006] A mushroom cultivation opening device, comprising an opening wheel, the opening wheel is provided with a punching needle, the opening wheel is arranged in a circumferential arrangement, the mushroom bag passes through the center of the circle where the circumferentially arranged opening wheel is located, and the opening wheel rolls on the mushroom bag, characterized in that: the opening wheel comprises an opening disc, an expansion disc and a linkage disc, the expansion disc is arranged in the middle of the opening wheel, the opening disc and the linkage disc are arranged on both sides of the expansion disc respectively, the opening disc, the expansion disc and the linkage disc are sequentially connected by bolts, the side wall of the opening disc is arranged obliquely, the opening disc has an outward expansion structure, the inner side of the opening disc is provided with a first support bone and a second support bone, the side wall of the opening disc and the first support bone and the second support bone form a linkage embedded groove, the linkage disc has a linkage protrusion, the linkage protrusion is arranged obliquely, the linkage protrusion is adapted to the linkage embedded groove, the linkage protrusion is alternately embedded in the linkage embedded groove, the linkage disc is connected with the opening disc of the adjacent opening wheel and rotates with the opening wheel.

[0007] The middle part of the opening wheel is connected with a support frame through a mounting shaft, the opening wheel rotates on the mounting shaft, the lower part of the support frame is connected with a rotating rod, the inner end of the rotating rod is sleeved on a lower mounting ring, the rotating rod rotates on the lower mounting ring, and the opening wheels are uniformly distributed on the outer side of the lower mounting ring through the support frame. ADVANTAGEOUS EFFECTS

[0008] 1. The connection between the linkage protrusion and the linkage embedded slot is embedded connection, which can effectively prevent the disconnection between the opening wheels, or the dislocation or movement between the opening wheels during high-speed operation, and the triangular opening of the fungus bag is more uniform. The adjusting spring limits the movement range of the opening wheel while adjusting the swing range of the opening wheel. Due to the outward expansion structure of the opening disc and the linkage protrusion, the contact range between the linkage protrusion and the linkage embedded slot is increased. When the opening wheel swings outward, the opening wheel maintains a circular structure distribution while expanding outward, which adapts to the cylindrical structure of the fungus bag, reduces the possibility of damaging the arrangement pattern due to the external force of the opening wheel on the fungus bag, and enables the fungus bag to move at a uniform speed along a straight line, thereby reducing the possibility of fungus bag damage and making the triangular opening of the fungus bag more uniform.

[0009] 2. The invention prevents problems caused by uneven density of fungus bags and higher local hardness, such as fungus bag deviation. The opening wheel has linkage, and when a single opening wheel is forced to move outward, it can drive all opening wheels to move outward synchronously. The triangular opening of the fungus bag is more uniform, reducing the possibility of fungus bag jamming, reducing the possibility of cleaning and maintenance due to jamming, improving work efficiency, and prolonging service life.

[0010] 3. The linkage between the opening wheels enables the linkage protrusion to alternately embed in the linkage embedded slot without jamming, and reduces the possibility of single opening wheel stoppage and dragging during the fungus bag passing process, thereby reducing the possibility of fungus bag scratches and bag scattering, strictly controlling the punching position on the spore layer or mycelium extension, preventing contamination and insect damage, improving work efficiency, and reducing waste rate.

[0011] 4. The synchronous rotation of all opening wheels makes the fungus bag force uniform, prevents the fungus bag from twisting during the advancing process, makes the fungus bag outside punching uniform, improves the convenience of spore cultivation, ensures the relative distance between the openings on the fungus bag, reduces the possibility of bag breaking, prevents contamination and insect damage, and improves the effective utilization rate of fungus bags.

The fungus bag can be driven to move forward in the circumferential direction, which saves manpower and makes the stress on the fungus bag uniform in the circumferential direction, improves the situation that the pushing force is offset relative to the axis of the opening array, reduces the resulting jamming, and further reduces the generation of broken bags. The punching position can be strictly controlled on the strain layer or the mycelium extension, preventing contamination and insect damage, improving the opening quality and efficiency. Embodiment
