Description

Technical Field

[0001] The invention relates to the technical field of edible fungus production and processing, and in particular to an edible fungus cutting machine. Background Art

[0002] At present, when cultivating edible fungi such as mushrooms and wood ears, the corresponding raw materials are usually poured into cylindrical plastic bags and tied tightly, and then cut on the fungus bag. Opening holes in the fungus bag is an important link in the fungus cultivation process. The main purpose is to increase the ventilation in the fungus bag and promote the growth and development of mycelium. Under the influence of environmental, temperature and other conditions, the corresponding edible fungi will grow at the cut.

[0003] The existing mushroom bags are usually cut manually, using a mushroom bag opening machine or a piercing machine according to the production scale and conditions. However, the above methods can generally only cut the two ends or sides of the mushroom bag, and are not convenient for cutting the two ends and sides of the mushroom bag at the same time. When cutting the two ends and sides of the mushroom bag, not only is it necessary to repeatedly put the mushroom bag into the mushroom bag cutting machine, but also it is necessary to manually adjust the direction of the mushroom bag, which increases the workload of the staff. Therefore, an edible mushroom cutting machine is proposed. Summary of the invention

[0004] The object of the present invention is to provide an edible mushroom cutting machine, which can achieve uniform cutting of both ends and sides of a mushroom bag at the same time, and can also separately disassemble the rectangular blade and the circular blade to respectively make uniform cutting of both ends or sides of the mushroom bag.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an edible mushroom cutting machine, comprising a base, first support rods are fixedly connected to both sides of the upper surface of the base, a horizontal frame is fixedly connected to the top of the first support rod, a horizontal tube is rotatably connected to the inside of the horizontal frame through a bearing, a cylinder is fixedly connected to the outer surface of the horizontal tube, a plurality of rectangular blades are detachably connected to the outer surface of the cylinder, and the rectangular blades are distributed on the outer surface of the cylinder in the form of a circular array; The interior of the horizontal tube is rotatably connected to a circular shaft through a bearing, and circular blades are detachably connected to both ends of the circular shaft. The two circular blades are symmetrical to each other with the geometric center of the circular shaft as the symmetry center, and the radius of the circular blade is greater than the vertical distance from the tip of the rectangular blade to the circular shaft; A linkage mechanism is arranged between the horizontal frame, the horizontal tube and the circular shaft, and the linkage mechanism includes a first motor fixedly connected to the side of the horizontal frame, the output end of the first motor is fixedly connected to a first gear, the internal rotation of the horizontal frame is connected to a double-headed gear shaft meshing with the first gear, the outer surface of the horizontal tube is fixedly connected to a second gear meshing with the double-headed gear shaft, and the outer surface of the circular shaft is fixedly connected to a third gear meshing with the double-headed gear shaft.

[0006] By adopting the above technical scheme, through the coordination arrangement among the base, the circular blade, the horizontal frame, the circular shaft, the horizontal tube, the cylinder, the rectangular blade, the second gear, the third gear, the double-headed gear shaft, the first gear, the first motor, the third support rod and the first support rod, the rotation of the circular shaft and the horizontal tube is relatively independent, and the circular shaft and the horizontal tube are driven to rotate at the same time through the linkage mechanism, specifically: the first motor is meshed with the double-headed gear shaft through the first gear, and the double-headed gear shaft is meshed with the second gear and the third gear respectively to drive the horizontal tube and the circular shaft to rotate, and the horizontal tube drives the cylinder to rotate, and the cylinder can contact with the mushroom bag to drive the mushroom bag to rotate, so as to drive the mushroom bag to rotate. The partitions rotate between them, and the circular shaft can rotate relative to the horizontal tube and the cylinder. When the horizontal tube drives the cylinder to rotate, the rectangular blade on the cylinder cuts the side of the mushroom bag. When the circular shaft rotates, the circular shaft drives the circular blade to rotate, and cuts the two ends of the mushroom bag, so as to achieve uniform cutting of the two ends and the sides of the mushroom bag at the same time. According to the placement needs of the mushroom bag, the rectangular blade and the circular blade can be disassembled to make uniform cutting on the two ends or the sides of the mushroom bag respectively. In summary, the device can achieve uniform cutting on the two ends and the sides of the mushroom bag at the same time, and can also remove the rectangular blade and the circular blade separately to make uniform cutting on the two ends or the sides of the mushroom bag respectively.

[0011] The present invention is further configured as follows: a roller is rotatably connected to the outer surface of the belt, and two rollers are arranged between two adjacent partitions.

[0018] By adopting the above technical solution, the feed tube is used to place the mushroom bags of edible fungi. When in use, the mushroom bags are put into the feed tube. The mushroom bags pass through the feed tube and fall on the center line of the belt. The protrusions can increase the friction between the mushroom bags and the feed tube, block the falling speed of the mushroom bags, and facilitate the transportation of the mushroom bags to the belt, ensuring that the openings at both ends of the mushroom bags are accurate.

[0019] The beneficial effects of the present invention are as follows: through the coordination among the base, the circular blade, the horizontal frame, the circular shaft, the horizontal tube, the cylinder, the rectangular blade, the second gear, the third gear, the double-headed gear shaft, the first gear, the first motor, the third support rod and the first support rod, the rotation of the circular shaft and the horizontal tube is relatively independent, and the circular shaft and the horizontal tube are simultaneously driven to rotate through the linkage mechanism, specifically: the first motor is meshed with the double-headed gear shaft through the first gear, and the double-headed gear shaft is respectively meshed with the second gear and the third gear for transmission, driving the horizontal tube and the circular shaft to rotate, and the horizontal tube drives the cylinder to rotate, and the cylinder can contact with the mushroom bag to drive the mushroom bag to rotate, so as to drive the mushroom bag to be separated The plates rotate between each other, and the circular shaft can rotate relative to the horizontal tube and the cylinder.
