Description

Technical Field

[0001] The utility model relates to the field of mushroom picking tools, in particular to an auxiliary picking device for mushroom cultivation. Background Art

[0002] In large-scale artificial cultivation of mushrooms like oyster mushrooms and king oyster mushrooms, these are typically grown using spawn sticks. Before planting, the sticks are evenly arranged from top to bottom on specialized cultivation racks. After a period of careful cultivation, mushrooms sprout from the ends of the sticks. When mature, workers harvest them between the racks.

[0003] For mushrooms growing on the lower layers of the cultivation racks, workers often need to bend over or even squat to pick them, which not only increases the difficulty of picking but also easily causes physical fatigue. To solve this problem, an innovative mushroom picking assist device has been launched on the market.

[0004] This assistive device primarily consists of an extension rod with a cutter cleverly positioned at its end. It's also equipped with a drive mechanism. Workers simply hold the upper end of the extension rod, precisely position the cutter against the desired mushroom, and then operate the drive mechanism. The cutter quickly and precisely cuts the mushroom, facilitating harvesting and significantly reducing the need for workers to frequently bend or squat.

[0005] However, while this auxiliary device improves picking efficiency to a certain extent, the angle of the cutter is fixed. The mushrooms at the ends of the mushroom sticks grow in different directions. Some grow horizontally, making them easy to pick with existing devices, while many grow upward or downward. In these situations, workers still need to squat or bend over to find the right angle to insert the cutter. Therefore, in most cases, this auxiliary device is not very effective in saving labor. Utility Model Content

[0006] In order to make up for the shortcomings of the existing technical problems, the purpose of the utility model is to provide a mushroom farming auxiliary picking device that can adjust the angle of the cutter according to the specific growth direction of the mushrooms, thereby significantly improving the adaptability and efficiency of the picking operation and effectively reducing the manpower consumption during the picking process.

[0007] In order to solve the problems of the prior art, the technical solutions of the present utility model are as follows:

[0008] A mushroom cultivation auxiliary picking device comprises a picking rod, a handle fixed to the upper end of the picking rod, a connecting frame fixed to the lower end of the picking rod, two sliding bars symmetrically slidably connected to the horizontal portion of the connecting frame, one end of the sliding bar extending toward one side of the connecting frame and rotatably mounted with a cutter;

[0009] A driving assembly for driving two sliding bars to drive the two cutters to open and close is installed on the outer wall of the picking rod, and a limiting assembly for limiting the angle of the cutter is installed on one end of the sliding bar close to the cutter.

[0010] Preferably, four embedding grooves are arranged in a circular array on the outer circumference of the picking rod with the axis of the picking rod as the center.

[0011] Preferably, the driving assembly includes connecting rings slidably mounted on both ends of the picking rod, a guide rod is fixed between the two connecting rings, and a pulling handle is fixed on the outer wall of one of the connecting rings at the upper end, and the pulling handle is located directly below the grip;

[0012] The end of the sliding bar away from the cutter is rotatably connected to the inclined rod through an axle pin, and the upper ends of the two inclined rods are rotatably connected to the outer wall of a connecting ring at the lower end through the axle pin;

[0013] The lower end of the picking rod is sleeved with a spring, one end of the spring is fixed to the top surface of the connecting frame, and the other end of the spring is fixed to the outer wall of a connecting ring at the lower end.

[0014] Preferably, a sleeve is fixed on the outer wall of the cutter close to the sliding bar, the two sleeves are located between the two sliding bars, the inner wall of the sleeve is rotatably connected to a rotating shaft through a bearing, and one end of the rotating shaft is fixed to the end of a sliding bar close to it.

[0015] Preferably, the limiting assembly includes a plurality of limiting protrusions fixed on the opposite sides of the two sleeves, and the plurality of limiting protrusions on each sleeve are distributed in a circular array with the axis of the sleeve as the center. A positioning groove is provided on the side of the sliding bar close to the sleeve corresponding to the position of the limiting protrusion, and the limiting protrusion abuts against the inner wall of the positioning groove.

[0016] Preferably, a blocking ring is formed on the top surface of the cutter, and a material receiving hopper is fixed to the inner wall of the connecting frame on one side close to the cutter. The material receiving hopper is located above the two sliding bars, and one side of the material receiving hopper extends toward the cutter.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] The utility model abandons the form of fixed cutting knife angle in traditional technology, and rotatably installs the cutting knife on the sliding bar. The driving component drives the sliding bar closer to drive the cutting knife to cut the mushrooms. After the mushrooms of the same angle are cut, the cutting knife can be rotated to adjust the cutting angle, and then the mushrooms of the corresponding growth angle can be picked. In this way, mushrooms growing at various angles can be picked by this device. During the picking process, workers do not need to squat or bend down, which significantly improves the adaptability and efficiency of the picking operation and effectively reduces the manpower consumption in the picking process.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] For example 1, please refer to Figures 1 to 5 This embodiment provides a mushroom cultivation auxiliary picking device, comprising a picking rod 1, on the outer circumference of which four embedding grooves 101 are arranged in a circular array with the axis of the picking rod 1 as the center, and a handle 2 is fixed to the upper end of the picking rod 1;

[0028] The operator of the device holds the handle 2 to perform the picking operation. The horizontal design of the handle 2 makes it easier for people to pick up the device.

[0029] A connecting frame 3 is fixed to the lower end of the picking rod 1. Two sliding bars 4 are symmetrically slidably connected to the horizontal portion 301 of the connecting frame 3. One end of the sliding bar 4 extends to one side of the connecting frame 3 and is fixed with a rotating shaft 12. The outer walls of the two rotating shafts 12 at one end thereof are rotatably connected to a sleeve 11 through a bearing. The two sleeves 11 are located between the two sliding bars 4. A cutter 5 is fixed to the outer wall of the sleeve 11.

[0030] The angle of the cutter 5 can be adjusted, which abandons the traditional fixed installation method of the cutter 5. It can be adjusted according to the specific situation during the picking process, so that workers can pick more mushrooms in a standing position directly, without having to bend down or squat to pick in various picking situations.

[0031] A plurality of limiting protrusions 13 are fixed to the opposite sides of the two sleeves 11. The limiting protrusions 13 on each sleeve 11 are distributed in a circular array with the axis of the sleeve 11 as the center. A positioning groove 14 is formed on the side of the sliding bar 4 close to the sleeve 11 at the position corresponding to the limiting protrusion 13. The limiting protrusion 13 abuts against the inner wall of the positioning groove 14.

[0032] The angle of the cutter 5 is limited by the limiting protrusion 13 and the positioning groove 14. The limiting protrusion 13 and the positioning groove 14 enable the cutter 5 to maintain a horizontal posture or a vertical upward posture. When in the horizontal posture, the cutter 5 can pick mushrooms growing upward or downward. When in the vertical posture, the cutter 5 can pick mushrooms growing horizontally.

[0033] Both ends of the picking rod 1 are slidably sleeved with connecting rings 6. Due to the setting of the embedded groove 101, the connecting ring 6 can only slide up and down and cannot rotate on the picking rod 1. A guide rod 7 is fixed between the two connecting rings 6. A pulling handle 8 is fixed on the outer wall of a connecting ring 6 at the upper end. The pulling handle 8 is located directly below the handle 2. The end of the sliding bar 4 away from the cutter 5 is rotatably connected to the inclined rod 9 through an axle pin. The upper ends of the two inclined rods 9 are rotatably connected to the outer wall of a connecting ring 6 at the lower end through an axle pin. The lower end of the picking rod 1 is sleeved with a spring 10. One end of the spring 10 is fixed to the top surface of the connecting frame 3, and the other end of the spring 10 is fixed to the outer wall of a connecting ring 6 at the lower end;

[0034] After the angle of the cutter 5 is adjusted, the cutter 5 is placed at the root of the mushroom to be picked, with the two cutters 5 located on both sides of the root. When picking, hold the handle 2 and tighten the pulling handle 8 to make the pulling handle 8 and the connecting ring 6 at the upper end move upward, and then pull the inclined rod 9, so that the two sliding bars 4 drive the two cutters 5 to approach for cutting and picking. When the two cutters 5 are close, the connecting ring 6 rises and can pull the spring 10 to stretch and store force. After releasing the pulling handle 8, the spring 10 contracts, driving the connecting ring 6 to descend, and pushing the two cutters 5 to open. All the mushrooms are picked, cut, and dropped on the ground and collected together.

[0035] For example 2, please refer to Figure 6, this embodiment provides a further technical solution based on the first embodiment. A retaining ring 16 is formed on the top surface of the cutter 5, and a receiving hopper 15 is fixed to the inner wall of the connecting frame 3 close to the cutter 5. The receiving hopper 15 is located above the two sliding bars 4, and one side of the receiving hopper 15 extends toward the cutter 5. When the cutter 5 is set horizontally to cut upward mushrooms, the mushrooms can directly fall into the space surrounded by the two retaining rings 16. The worker can directly operate the picking rod 1 to remove the mushrooms, or choose to shake them off directly on the ground for subsequent unified collection. When the cutter 5 is vertically upward to pick horizontally growing mushrooms, the mushrooms can fall into the receiving hopper 15 after being cut. Similarly, the worker can operate the picking rod 1 to remove the mushrooms, or choose to shake them off directly.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
