Description

Technical Field

[0001] This utility model relates to the field of mushroom stick unpacking technology, specifically an axial cutting mechanism for unpacking mushroom sticks. Background Technology

[0002] After the culture medium is filled into the mushroom bags, columnar mushroom logs are formed. These logs are then sterilized by drilling and high-temperature treatment before inoculation. Once the mycelium has grown, the mushroom bags need to be removed. Traditional manual bag removal has been gradually replaced by automatic bag removal machines. These machines perform circumferential and axial cuts on the mushroom bags. The circumferential cut is made near the bag's knot, and the axial cut intersects with the circumferential cut, thus separating the mushroom bags from the mushroom logs.

[0003] Traditional axial cutting mechanisms, lacking proper limiting devices, are prone to displacement of the mushroom substrate bags during cutting. This not only leads to inaccurate cutting positions and incomplete cuts but can also damage the mycelium inside the substrate, affecting its subsequent growth and use. After cutting, the bags need to be pried open from the substrate. Existing bag-peeling devices may not be able to completely pry the cut bags open to both sides, resulting in parts of the bag remaining attached to the substrate, hindering complete separation of the substrate from the bag. Utility Model Content

[0004] The purpose of this invention is to provide an axial cutting mechanism for removing mushroom sticks from bags, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an axial cutting mechanism for removing mushroom spawn bags, comprising a support frame on which a conveyor belt is mounted, and further comprising: Several storage shells are fixedly installed on the conveyor belt, and the storage shells are trapezoidal in shape with their openings facing upwards; The mounting bracket has a first fixing frame and a second fixing frame on both sides. The first fixing frame is equipped with a cutting component for axial cutting of the mushroom stick bag and a limiting component for limiting the mushroom stick.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 As shown, an axial cutting mechanism for removing mushroom spawn bags includes a support 1, a conveyor belt 2 mounted on the support 1, the conveyor belt 2 being mounted on the support 1 via a transmission roller and driven by a transmission device, which can be a motor. The connection between the conveyor belt 2, the transmission roller, and the transmission device is prior art and will not be described in detail in this application. It also includes: several storage shells 3 fixedly mounted on the conveyor belt 2, the storage shells 3 being trapezoidal designs with open openings facing upwards; and fixed frames 4 and 7 on both sides of the support 1. Fixed frame 4 is equipped with a cutting component 5 for axial cutting of the mushroom spawn bags, and a limiting component 6 for limiting the mushroom spawn bags is mounted on the cutting component 5. Fixed frame 7 is equipped with a bag-removing component 9 and a material pushing component 8 for peeling and removing the mushroom spawn bags.

[0016] When removing the mushroom sticks from their bags, the mushroom sticks are placed in the storage shell 3. Since the storage shell 3 is trapezoidal, it can accommodate mushroom sticks of different shapes. The mushroom sticks are moved to the fixed frame 4 by the conveyor belt 2. At this time, the cutting component 5 moves from the fixed frame 4 to the other side and cuts the bag on the mushroom stick. While the cutting component 5 is moving, the limiting component 6 moves synchronously on the mushroom stick. The limiting component 6 applies a downward pressure to the mushroom stick to prevent the mushroom stick from shifting during cutting and affecting the cutting effect. After the mushroom stick is cut, the conveyor belt 2 moves the mushroom stick to the fixed frame 7. The bag removal component 9 moves down to contact the top of the mushroom stick and then pries open the cut bag on the mushroom stick to both sides. Then the pushing component 8 works to separate the mushroom stick from the bag.

[0017] Based on the above implementation scheme, the cutting component 5 includes a hydraulic rod 51 fixedly installed on the fixed frame 4. A connecting rod 52 is fixedly installed on the piston rod of the hydraulic rod 51. A blade 53 for cutting the mushroom bag is fixedly installed at the bottom of the connecting rod 52. The limiting component 6 includes a fixed sleeve 61 welded to the top of the connecting rod 52. Two symmetrical vertical rods 62 are inserted into the inside of the fixed sleeve 61. A roller 63 is rotatably installed at the bottom of the vertical rod 62 through the mounting frame. A spring 64 is sleeved on the outside of the vertical rod 62. The blade 53 is fixedly installed at the bottom of the connecting rod 52 by bolts. The conveyor belt 2 moves the center of the storage shell 3 to the blade 53. The mushroom bag can be cut from the top cutting point by the blade 53. The two vertical rods 62 are symmetrically slidably installed in the fixed sleeve 61. The top of the spring 64 is fixed to the bottom of the fixed sleeve 61. The bottom of the spring 64 is fixed to the top of the mounting frame. The mounting frame is welded to the bottom of the vertical rod 62. The roller 63 is rotatably installed in the mounting frame.

[0018] When axially cutting the mushroom stick bag, the mushroom stick has already been processed by the previous process (circumferential cutting). Then, the mushroom stick is moved into the storage shell 3. Next, the hydraulic rod 51 drives the connecting rod 52 and the blade 53 to move from one side of the mushroom stick to the other side, cutting the outer bag body of the mushroom stick. While the connecting rod 52 is moving, the vertical rod 62 drives the roller 63 to press down on the mushroom stick, limiting the position of the mushroom stick. Since the vertical rod 62 is limited on the fixed sleeve 61 by the spring 64, the roller 63 can adapt to the size of the mushroom stick, limiting the mushroom stick in the storage shell 3 when cutting the mushroom stick, avoiding displacement of the mushroom stick during cutting and affecting the cutting effect.

[0019] Based on the above implementation scheme, the material pushing assembly 8 includes a hydraulic rod 2 81 fixedly installed on the fixed frame 2 7, and a push rod 82 fixedly installed on the piston rod of the hydraulic rod 2 81. The height of the push rod 82 is horizontal with the center position of the inner cavity of the storage shell 3. The bag removal assembly 9 includes a hydraulic rod 3 91 fixedly installed on the cantilevered part of the fixed frame 2 7, and a connecting block 92 fixedly installed on the piston rod of the hydraulic rod 3 91. Hydraulic rods 4 93 are fixedly installed on both sides of the connecting block 92, and hooks 94 are fixedly installed on the piston rods of the hydraulic rods 4 93. The two hydraulic rods 4 93 are mirror images installed on both sides of the connecting block 92. The piston rod of the hydraulic rod 3 91 is vertically downward.

[0020] After the cut mushroom sticks are moved to the lower part of the connecting block 92, the hydraulic rod three 91 drives the connecting block 92 to move down, so that the connecting block 92 presses on the top of the mushroom sticks. Then the hydraulic rod four 93 is activated, which drives the hook 94 to move to both sides of the connecting block 92. Since the hook 94 is set at an angle downward, the hook 94 will pry the cut bag apart to both sides of the mushroom sticks when it moves. Then the hydraulic rod two 81 is activated, which drives the push rod 82 to move towards the storage shell 3, pushing the mushroom sticks out of the storage shell 3 and separating the mushroom sticks from the bag.

[0021] It should be noted that: in this solution, the transmission equipment of conveyor belt 2, hydraulic rod 1 51, hydraulic rod 2 81, hydraulic rod 3 91 and hydraulic rod 4 93 are all electrically connected to the control terminal via wires, and the control terminal can be set on one side of the bracket 1 (not shown in the figure). The control terminal can be set as a PLC programmable logic controller to control the above-mentioned electrical equipment to work. The above should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can adopt conventional choices in the field. This technical solution will not be further elaborated in detail.
