Description

Technical Field

[0001] The utility model relates to the field of mushroom bag culture, in particular to a mushroom bag culture opening mechanism. Background Art

[0002] The existing patent (publication number: CN113692918B) proposes a mushroom bag culture hole-opening mechanism, which includes: a base, a support frame is provided on one side of the top of the base, a first support plate is connected between the inner walls of the upper part of the support frame, a punching mechanism, a punching mechanism is provided on the first support plate, a first connecting rod, a first connecting rod is slidably provided on the punching mechanism, and an arc-shaped punching plate is provided on the inner side of the first connecting rod; a driving mechanism, a driving mechanism is connected between the middle part of the support frame and the top of the base. However, in this device, "the mushroom bag slides down into the blanking bucket through the arc-shaped slide to complete automatic loading". The blanking bucket is fixed in size, so this device only has a good feeding effect for mushroom bags of fixed size. Larger mushroom bags cannot enter, and smaller mushroom bags are prone to displacement after being placed in due to lack of fixation, and their adaptability is limited. Summary of the Invention

[0003] In response to the above-mentioned deficiencies in the prior art, the utility model provides a mushroom bag culture hole-making mechanism in which the No. 1 and No. 2 hole-making wheels rotate synchronously when the mushroom bag passes through the center of a connecting body of the No. 1 and No. 2 hole-making wheels, and the holes are made on the surface of the culture bag. During the installation process of the No. 1 and No. 2 hole-making wheels, only the outer fixing hole and the inner fixing hole are fixedly connected by fastening screws and fastening nuts. A spring is provided between the spring positioning screw and the outer connecting hole, so that the hole-making wheel connecting block itself can generate a certain bending, so that the connecting body of the No. 1 and No. 2 hole-making wheels can expand outward, thereby adapting to the hole-making operation of mushroom bags of different diameters and increasing the processing adaptability of the device.

[0004] The purpose of this utility model is achieved through the following technical solutions:

The hole-punching wheel connecting platform of one part of the hole-punching wheel connecting block is rotatably connected to the first hole-punching wheel, and the hole-punching wheel connecting platform of another part of the hole-punching wheel connecting block is rotatably connected to the second hole-punching wheel.

[0008] Beneficial effects: 1. In the utility model, when the mushroom bag passes through the center of the connecting body of the No. 1 and No. 2 hole-punching wheels, the No. 1 and No. 2 hole-punching wheels rotate synchronously, and the hole-punching operation is performed on the surface of the culture bag. During the installation process of the No. 1 and No. 2 hole-punching wheels, only the outer fixing hole and the inner fixing hole are fixedly connected by fastening screws and fastening nuts. A spring is provided between the spring positioning screw and the outer connecting hole, so that the hole-punching wheel connecting block itself can generate a certain bending, so that the connecting body of the No. 1 and No. 2 hole-punching wheels can expand outward, so as to adapt to the hole-punching operation of mushroom bags of different diameters, thereby increasing the processing adaptability of this device.

[0009] 2. During the automatic hole-opening operation of the culture bag of the utility model, the No. 1 hole-opening wheel and the No. 2 hole-opening wheel engage with each other to form a ring-shaped mechanism. The No. 1 hole-opening wheel and the No. 2 hole-opening wheel are arranged in a ring and move synchronously, so that the holes on the surface of the culture bag are dense and uniform, and the hole opening is stable and efficient.

[0010] 3. The synchronous movement of the No. 1 hole-punching wheel and the No. 2 hole-punching wheel of the utility model ensures that the culture bag is subjected to balanced force during the hole-punching process, avoids deviation of the movement trajectory during the hole-punching process and causes bag breakage, and ensures the hole-punching quality.

The surface of the hole opening wheel connecting block 48 has an outer fixing hole 49 and an outer connecting hole 51. The outer fixing hole 49 corresponds to the position of the inner fixing hole 46.

[0020] Example 2:

[0021] The external connection hole 51 of the present invention corresponds to the position of the internal connection hole 47, and the fastening screw 53 passes through the external fixing hole 49 and the internal fixing hole 46 in sequence and is threadedly connected to the fastening nut 28. The top nut of the fastening screw 53 is pressed tightly against the outside of the perforated wheel connecting block 48, and the fastening nut 28 is pressed tightly against the inside of the side support ear 45. The spring positioning screw 52 passes through the reset spring 99, the external connection hole 51, the internal connection hole 47 in sequence and is threadedly connected to the spring positioning nut 59, and the top of the reset spring 99 is pressed tightly against the lower side of the top nut of the spring positioning screw 52.

[0022] Example 3:

[0023] The bottom of the reset spring 99 of the utility model is pressed against the surface of the perforated wheel connecting block 48, and the spring positioning nut 59 is pressed against the inner side of the side support ear 45. The perforated wheel connecting block 48 has a perforated wheel connecting platform 61 on the side away from the inner support frame 44.

When the mushroom bag passes through the center of the connecting body of the first perforated wheel 31 and the second perforated wheel 32, the first perforated wheel 31 and the second perforated wheel 32 are rotated. The No. 2 hole-punching wheel 32 rotates synchronously, and the hole-punching needle 33 performs hole-punching operation on the surface of the culture bag. During the installation process of the No. 1 hole-punching wheel 31 and the No. 2 hole-punching wheel 32, only the outer fixing hole 49 and the inner fixing hole 46 are fixedly connected by the fastening screw 53 and the fastening nut 28. A spring is provided between the spring positioning screw 52 and the outer connection hole 51, so that the hole-punching wheel connecting block 48 itself can generate a certain bending, so that the connecting body of the No. 1 hole-punching wheel 31 and the No. 2 hole-punching wheel 32 can expand outward, so as to adapt to the hole-punching operation of bacteria bags of different diameters, thereby increasing the processing adaptability of this device.

During the automatic hole-punching operation of the culture bag, the No. 1 hole-punching wheel 31 and the No. 2 hole-punching wheel 32 are engaged with each other to form an annular mechanism. The No. 1 hole-punching wheel 31 and the No. 2 hole-punching wheel 32 arranged in an annular shape and moving synchronously make the holes on the surface of the culture bag dense and uniform, and the holes are opened stably and efficiently. The No. 1 hole-punching wheel 31 and the No. 2 hole-punching wheel 32 are both provided with a hole-punching needle 33 on the outside. The synchronous movement of the No. 1 hole-punching wheel 31 and the No. 2 hole-punching wheel 32 ensures that the culture bag is subjected to balanced force during the hole-punching process, avoids the movement trajectory from deviating during the hole-punching process and causing the bag to break, and ensures the hole-punching quality. The sidewalls 65 on either side of the first perforating wheel 31 are outwardly flared and inclined, with recesses 66 provided on each side. The second perforating wheel 32 is also provided with protrusions 67, which engage with the recesses 66 of the first perforating wheel 31. The connection between the first and second perforating wheels can expand outward to accommodate perforation of bags of varying diameters. The synchronized movement of the first and second perforating wheels ensures balanced force on the perforated bags, preventing bag breakage caused by deviation in the perforation trajectory and ensuring high perforation quality.
