Description

Technical Field

[0001] This invention relates to a bacterial inoculation machine, belonging to the field of agricultural machinery technology. Background Technology

[0002] Inoculation machines are key pieces of equipment in edible mushroom production, used to inoculate spawn into culture media or bags to ensure rapid mycelial growth and uniform distribution of superior spawn. The design of inoculation machines can improve inoculation efficiency, reduce contamination rates, decrease manual labor, and increase production efficiency. Existing inoculation machines, such as the edible mushroom inoculation machine disclosed in publication number CN103155798A, have a simple structure. They rely solely on the impact force of a cylinder to feed solid spawn into a steel pipe using a mechanical attachment, then the machine moves downwards, punctures the bag, and ejects the spawn into the culture medium. This inoculation method cannot achieve uniform spawn distribution into the culture medium. Under high production volumes, inconsistent inoculation amounts can occur, leading to unstable cultivation results. Furthermore, it has poor adaptability to spawn types, is incompatible with all types of culture media, has a narrow application range, and a low degree of automation.

[0003] Therefore, there is an urgent need to develop a new type of intelligent inoculation machine to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing inoculation machines, such as their inability to evenly inoculate the culture medium, inconsistent inoculation amounts leading to unstable culture results, narrow applicability, and low automation.

However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

The left and right sides of the side-clamping lifting frame 3 are fixedly connected to the side-clamping lifting cylinder 4. The side-clamping lifting cylinder 4 is fixedly installed on the frame 1.

[0038] The left and right sides of the lifting and inoculating mechanism 2 are slidably connected to the frame 2 through the second auxiliary slide rail group 8. Pneumatic clamping mechanisms 5 are processed on both the left and right sides of the frame 2. There are a total of 4 pneumatic clamping mechanisms 5. From a horizontal perspective, the four pneumatic clamping mechanisms 5 are arranged in a rectangular shape.

[0039] The pneumatic clamping mechanism 5 includes a clamping cylinder 51 and a clamping part 52. The output end of the clamping cylinder 51 is equipped with the clamping part 52. The clamping part 52 is machined with multiple arc-shaped limiting grooves 53. The multiple arc-shaped limiting grooves 53 are continuously arranged in a wavy line. The arc-shaped surface of each arc-shaped limiting groove 53 is an arc-shaped contour surface of the outer wall of the solid mushroom bag.

[0040] The lifting transmission mechanism 7 includes a lifting motor 61, a drive sprocket 62, a driven sprocket 63, and a transmission chain 64. The lifting motor 61 is fixedly mounted on the frame 2. The drive sprocket 62 is installed at the output end of the lifting motor 61. The driven sprocket 63 is rotatably mounted on the frame 2. The drive sprocket 62 and the driven sprocket 63 are connected through the transmission chain 64. The movable frame 21 has ears extending from both the left and right ends. The transmission chain 64 is fixedly connected to the ears of the movable frame 21. When the lifting motor 61 is started, the drive sprocket 62 and the driven sprocket 63 drive the transmission chain 64 to move, and the movable frame 21 connected to the transmission chain 64 also moves up and down accordingly.

[0041] The lifting and inoculation mechanism 2 includes a movable frame 21, a rotary motor 22, a driving pulley 23, a driven pulley 24, a connecting shaft 25, a rotary feeding part 26, a transmission belt 27, and a distributing trough 28. The rotary motor 22 is fixedly installed on the top of the movable frame 21. The driving pulley 23 is installed at the output end of the rotary motor 22. Multiple driven pulleys 24 are rotatably installed on the movable frame 21. The driving pulley 23 and the multiple driven pulleys 24 are connected through the transmission belt 27. The connecting shaft 25 is installed at the bottom of the driven pulleys 24. The rotary feeding part 26 is installed at the bottom of the connecting shaft 25.

[0042] The number of driven pulleys 24 is 16, and one driving pulley 23 passes through... Figure 8 The transmission belt 27, as shown, or other feasible arrangements, drives the 16 driven pulleys 24 to rotate.

The rotating blade 262 is arranged on one side of the rotating feed spring 263. The rotating feed unit 26 is rotatably disposed inside the conical chamber structure. At the same time, the bottom of the rotating feed spring 263 passes through the inoculum outlet of the conical chamber structure. When the driven pulley 24 drives the connecting shaft 25 to rotate, the connecting shaft 25 drives the rotating feed unit 26 to rotate synchronously. The rotating blade 262 and the rotating feed spring 263 work together to puncture the culture medium bag, while the rotating feed spring 263 acts as a feeding auger to evenly implant the inoculum into the culture medium bag.

[0045] The frame 1 is equipped with a crushing and feeding mechanism 9, which is a prior art feeding and crushing mechanism. It has a feeding roller inside, feeds from the top, and has a discharge port at the bottom. The discharge port of the crushing and feeding mechanism 9 passes through the movable frame 21 and communicates with the inside of the material distribution trough 28.

[0046] The frame 1 is also equipped with sensors to monitor the material transmission position.

[0047] A conveying mechanism 10 is provided on the frame 1 directly below the lifting and inoculation mechanism 2. The conveying mechanism 10 is a conventional transportation and transmission platform of existing technology, such as a motor-driven roller type or chain type.

[0048] The specific workflow of this embodiment, i.e., a bacterial inoculation method implemented based on this embodiment, is as follows:

[0049] Step 1: Place 16 culture medium bags into a rectangular basket, in the same arrangement as the driven pulley 34.

[0050] Step 2: Start the conveyor mechanism 10. The solid inoculum bag moves in the rectangular basket with the conveyor mechanism 10 to directly below the lifting inoculum collection mechanism 2.

[0051] Step 3: Activate the side clamping lifting cylinder 4 to lower the side clamping lifting frame 4 to the front and rear sides of the solid mushroom bag;

[0052] Step 4: Activate the clamping cylinder 51 of the pneumatic clamping mechanism 5. The clamping cylinder 51 drives the clamping part 52 to clamp the solid mushroom bag from the front, back, left and right sides.

[0053] Step 5: Start the lifting transmission mechanism 6 to drive the lifting inoculation mechanism 2 to rise until the discharge port of the crushing and feeding mechanism 9 is connected to the distribution tank 28. Then start the crushing and feeding mechanism 9 to transport the inoculum from the crushing and feeding mechanism 9 to the distribution tank 28.

[0054] Step 6: Start the lifting motor 61, so that the lifting transmission mechanism 6 drives the lifting inoculation mechanism 2 to descend until the rotating feed part 26 on the connecting shaft 25 pierces and inserts into the culture medium bag. Start the rotating motor 22 to make the rotating feed part 26 rotate, so that the inoculum in the dispensing trough 28 is evenly implanted into the culture medium bag.

[0055] Step 7: Start the lifting motor 61 to make the lifting transmission mechanism 6 drive the lifting inoculation mechanism 2 to rise until the rotating feeding part 26 is separated from the culture medium bag.

[0056] Step 8: Start the conveying mechanism 10 to move the culture medium bag after inoculation away from the workstation for the next stage of processing.

[0057] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be permuted and combined. Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutation and combination.
