A morel mushroom harvesting vehicle

Abstract

This utility model discloses a morel mushroom harvesting vehicle, belonging to the field of morel mushroom harvesting technology. It aims to solve the problems of existing mechanical harvesting methods, which easily lead to the breakage of delicate morel mushrooms and difficulty in separating the soil from the roots, resulting in high harvesting losses and high impurity content. The device includes a walking frame with a power supply and control unit, and multiple height-adjustable harvesting mechanisms at the bottom. The harvesting mechanism adopts a low-stress shearing design, including an inclined harvesting frame with a stationary blade at the front end. A sliding plate at the bottom drives a moving blade in a reciprocating translational motion. The moving blade is shorter than the stationary blade to form a guiding and protective structure for the morel mushrooms. A flexible brush roller is located above the stationary blade to gently sweep the sheared morel mushrooms off. An intermittent conveying component is located at the bottom of the harvesting frame to transport the morel mushrooms and filter out the soil. The drive component drives the sliding plate through a crank-connecting rod mechanism. This device achieves flexible, contour-following harvesting of morel mushrooms, effectively reducing the mushroom breakage rate and soil content while replacing manual labor.

Description

Technical Field

[0001] This utility model relates to the field of morel mushroom harvesting technology, and in particular to a morel mushroom harvesting vehicle. Background Technology

[0002] Morel mushrooms, a precious edible fungus, have an uneven cap surface and an extremely delicate texture. They typically grow in soft furrows or understory soil. Currently, morel harvesting faces the dual challenges of low manual efficiency and high mechanical wear and tear. Traditional agricultural harvesting machinery often uses rotary blades or rollers. This high-speed "impact cutting" easily generates strong vibrations and centrifugal forces, causing the fragile caps of morels to shatter or separate from the stem upon contact, severely damaging the integrity and commercial value of the morels. Furthermore, due to the poor micro-level flatness of the planting ground, harvesting equipment at a fixed height is prone to problems such as the blades cutting into the soil (leading to blade damage and mushroom contamination) or cutting too high (resulting in excessively long stubble and waste). Therefore, designing equipment that can adapt to uneven ground and employ a "low-impact, flexible" method for complete harvesting is a pressing technical challenge. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing agricultural machinery in harvesting brittle fungi such as morels, which suffer from high fungal damage rates due to the violent cutting method and difficulty in effectively separating the fungal body from the root soil during harvesting, resulting in high subsequent cleaning costs and low yield. The invention proposes a morel harvesting vehicle based on contour shearing and flexible sweeping.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A morel mushroom harvesting vehicle includes a walking frame with multiple harvesting mechanisms at the bottom of the walking frame. The harvesting mechanism includes a harvesting frame, which is inclinedly set at the bottom of the walking frame. One end of the harvesting frame is fixedly connected to a plurality of stationary blades, and the bottom of the harvesting frame is slidably connected to a slide plate. One side of the slide plate is fixedly connected to a plurality of moving blades that cooperate with the stationary blades. The length of the moving blades is shorter than that of the stationary blades. A brush roller is rotatably connected between the two sides of the harvesting frame, and the brush roller is located above the stationary blade. A drive assembly, which is disposed at the bottom of the harvesting frame for driving the slide plate to move; A conveying assembly is located at the bottom of the harvesting frame and is used to transport morel mushrooms.

[0005] As a further embodiment of this utility model, the driving assembly includes a driving rod, a swing rod, and a driving block. The driving rod rotates on one outer wall of the harvesting frame. A driving disk is fixedly connected to the bottom of the driving rod, and a driving shaft is eccentrically fixed to the bottom of the driving disk. The swing rod is rotatably connected to the bottom of the harvesting frame. A connecting rod is rotatably connected between one end of the swing rod and the driving shaft. The driving block is fixed to one side of the sliding plate. A U-shaped driving groove is provided on one side of the driving block. A push rod is fixedly connected to the end of the swing rod away from the connecting rod, and the push rod is slidably connected to the driving groove.

[0006] As a further embodiment of this utility model, a motor is fixedly connected to one side of the outer wall of the harvesting frame, and one end of the motor output shaft is connected to the drive rod through a bevel gear transmission.

[0007] As a further embodiment of this invention, the brush roller is driven by a belt and pulley around the circumference of the motor output shaft.

[0008] As a further embodiment of this utility model, the conveying assembly includes two conveying rollers, both of which rotate between the two sides of the harvesting frame. Multiple conveyor belts are connected between the two conveying rollers, and gaps are provided between adjacent conveyor belts.

[0009] As a further embodiment of this utility model, an intermediate shaft is rotatably connected to one side of the outer wall of the harvesting frame, and one end of one of the conveying rollers rotatably passes through the harvesting frame and is driven by gears through the intermediate shaft. The intermediate shaft is driven by a belt pulley to the circumference of the motor output shaft.

[0010] As a further embodiment of this utility model, the top of the harvesting frame is fixedly connected to two guide rods, which slide through the top of the walking frame. The top of the harvesting frame is rotatably connected to a screw, which threadedly passes through the top of the walking frame.

[0011] Working Principle: In this application, the walking frame is driven by rollers and a drive motor. The height of the harvesting mechanism is first adjusted according to the height of the cultivated surface. During adjustment, the screw is rotated, causing the harvesting frame to move up and down. During harvesting, the motor and walking frame are started. The motor drives the drive rod to rotate via a bevel gear. The drive rod drives the drive disc and drive shaft to rotate. The drive rod pushes and pulls the swing rod via a connecting rod, causing it to swing. The push rod at one end of the swing rod pushes the drive block and slide plate to move, causing the moving blade and stationary blade to move relative to each other. The shearing action between the moving and stationary blades harvests the morel mushrooms. When the motor starts, it also drives the brush roller to rotate rapidly via a belt pulley, sweeping the harvested morel mushrooms onto the conveyor belt. Simultaneously, the motor drives the intermediate shaft to rotate via the belt pulley, and the gear drives the conveyor roller to rotate, causing the conveyor belt to rotate and transport the morel mushrooms to the other end of the harvesting frame. A collection frame can be set at the other end to collect the morel mushrooms. The gaps between the conveyor belts help the soil fall off.

[0012] Beneficial effects: 1. By converting rotational motion into the reciprocating translational motion of a sliding plate through a drive component, the stipe is supported by a stationary blade while the moving blade cuts it. This cutting method minimizes the physical impact on morel mushrooms, effectively preventing the cap from shattering. Simultaneously, the moving blade is designed to be shorter than the stationary blade, allowing the stationary blade to pre-sort and straighten the stipe before cutting.

[0013] 2. To address the issue of morel mushrooms easily collapsing and piling up after cutting, a brush roller located above the stationary blade was installed. Driven by a motor, the brush roller rotates rapidly. Its flexible bristles generate a dual force of "airflow + contact" without damaging the mushroom surface, immediately "sweeping" the cut morel mushrooms into the subsequent conveyor assembly, preventing secondary cutting or crushing caused by subsequent mushrooms collapsing. Combined with a gapped conveyor belt design, vibration during transport naturally dislodges soil adhering to the stems, achieving simultaneous harvesting and initial cleaning.

[0014] 3. A lifting and adjusting mechanism consisting of a screw and guide rod allows operators to fine-tune the ground clearance of the harvesting frame according to different ridge heights and the growth height of morel mushrooms. This not only ensures a consistent stubble height, maximizing the retention of edible portions, but also prevents the blades from directly cutting into the soil. It adapts to complex understory or greenhouse planting environments, significantly improving the automation level of harvesting operations and the marketability of the finished product.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In one embodiment: Refer to Figures 1-5 A harvesting vehicle includes: a walking frame 1, with multiple harvesting mechanisms 2 installed at the bottom of the walking frame 1. The spacing between adjacent harvesting mechanisms 2 typically matches the row spacing for morel mushroom cultivation. Each harvesting mechanism 2 includes a harvesting frame 3, which is a rectangular frame structure made of stainless steel. The harvesting frame 3 is angled at the bottom of the walking frame 1, allowing harvesting from one end while preventing excessive soil from entering the frame during harvesting.

[0019] A battery pack and a control box are also fixedly installed on the walking frame 1. The motor 19 and the walking motor are electrically connected to the control box and are powered by the battery pack.

[0020] Two guide rods 5, cylindrical in shape, are fixedly connected to the top of the harvesting frame 3. These guide rods slidably pass through the top of the traveling frame 1, guiding the harvesting frame 3 as it moves up and down, preventing it from shifting. A screw 4 is also rotatably connected to the top of the harvesting frame 3 via a bearing. The screw 4 also passes through the top of the traveling frame 1 and is threadedly engaged with it. In actual use, the height of the harvesting mechanism 2 needs to be adjusted according to the height of the cultivated surface in the morel mushroom planting area. The operator simply rotates the screw 4, and through the threaded transmission between the screw 4 and the traveling frame 1, the harvesting frame 3 moves up and down along the axis of the guide rods 5 until the stationary blade 6 and the brush roller 9 reach the appropriate working height, ensuring that the stationary blade 6 is close to the ground.

[0021] Multiple stationary blades 6 are fixedly connected to one end of the harvesting frame 3. These stationary blades 6 are evenly distributed along the length of the harvesting frame 3, with the spacing between adjacent blades 6 matching the common growth spacing of morel mushrooms, ensuring that each morel mushroom corresponds to a position between two stationary blades 6. A sliding plate 7 is slidably connected to the bottom of the harvesting frame 3. The sliding plate 7 is made of wear-resistant steel plate, and its length is the same as the length of the harvesting frame 3, allowing it to slide smoothly at the bottom of the harvesting frame 3. Multiple moving blades 8 are fixedly connected to the side of the sliding plate 7 closest to the stationary blades 6. The moving blades 8 correspond one-to-one with the stationary blades 6, and the length of the moving blades 8 is shorter than that of the stationary blades 6, forming a tiered structure of "stationary blade guiding, moving blade shearing." During harvesting, the stationary blades 6 first contact and straighten the morel mushroom stem to prevent it from falling over. Then, the moving blades 8 perform low-impact shearing, effectively avoiding the brittle cap from breaking or separating from the stem due to direct impact from the blades, facilitating the morel mushroom to enter between the stationary blades 6 before cutting.

[0022] A brush roller 9 is rotatably connected between the two sides of the harvesting frame 3. The brush roller 9 is located above the stationary blade 6, and its axis is parallel to the length direction of the harvesting frame 3. The roller body of the brush roller 9 is a hollow steel pipe structure with multiple brush bristle mounting holes evenly distributed on its surface. The brush bristles are made of soft and elastic nylon material, and the length of the brush bristles is set according to the common height of morel mushrooms to ensure that the brush bristles can smoothly sweep the harvested morel mushrooms when the brush roller 9 rotates. That is, the motor drives the brush roller 9 to rotate towards the conveyor assembly. The brush roller 9 uses flexible long nylon bristles to gently sweep the cut and tilted morel mushrooms onto the conveyor belt 21 behind it without damaging the morel mushroom caps, using the rotating airflow and the light contact of the bristles. A drive assembly is also provided at the bottom of the harvesting frame 3 to drive the sliding plate 7 to move the moving blade 8 back and forth, so as to achieve the cooperation of cutting with the stationary blade 6.

[0023] This application can be used in the field of mushroom harvesting, or in other fields applicable to this application.

[0024] In another embodiment: Reference Figures 1-5 A morel mushroom harvesting vehicle, applied in the field of morel mushroom harvesting, has a structure that is basically the same as the aforementioned embodiments, the difference being:

[0025] The drive assembly includes a drive rod 10, a swing rod 16, and a drive block 14. The drive rod 10 is rotatably connected to one side of the outer wall of the harvesting frame 3 via bearings. A drive disk 11, which is a circular plate, is welded and fixed to the bottom of the drive rod 10. A drive shaft 12 is fixed at an eccentric position at the bottom of the drive disk 11. The drive shaft 12 is perpendicular to the drive disk 11 and is rotatably connected to one end of the connecting rod 13 via bearings. The swing rod 16 is rotatably connected to a support fixed to the bottom of the harvesting frame 3. One end of the swing rod 16 is also rotatably connected to the other end of the connecting rod 13 via bearings, forming a crank-connecting rod mechanism. The drive block 14 is welded and fixed to one side of the slide plate 7. A U-shaped drive groove 15 is provided on one side of the drive block 14. A dust cover (not shown in the figure) can be installed on the outside of the drive groove 15 to prevent soil from entering and causing mechanical jamming. The width of the drive groove 15 is adapted to the diameter of the push rod 18. The end of the swing rod 16 away from the connecting rod 13 is welded and fixed to the push rod 18, which is slidably connected to the drive groove 15. When the drive disc 11 drives the drive shaft 12 to rotate, the connecting rod 13 pushes and pulls the swing rod 16 to swing back and forth around the support. The swing rod 16 drives the push rod 18 to slide in the drive groove 15, which in turn pushes the drive block 14 to drive the slide plate 7 to move back and forth, realizing the relative shearing motion between the moving blade 8 and the stationary blade 6.

[0026] A motor 19 is fixedly connected to one outer wall of the harvesting frame 3 via a motor bracket. The motor 19 is a stepper motor, and its speed can be adjusted according to the harvesting speed requirements. A driving bevel gear is fixed to one end of the output shaft of the motor 19, and a driven bevel gear is fixed to the top of the drive rod 10. The driving bevel gear and the driven bevel gear mesh with each other to form a bevel gear transmission mechanism, ensuring that the motor 19 can drive the drive rod 10 to rotate stably after starting. At the same time, a driving pulley is fixed on the circumference of the output shaft of the motor 19, and one end of the brush roller 9 extends to the outside of the harvesting frame 3 and is fixed with a driven pulley. The driving pulley and the driven pulley are connected by a belt drive, so that when the motor 19 starts, it can synchronously drive the brush roller 9 to rotate quickly, which facilitates sweeping the harvested morel mushrooms backward.

[0027] The bottom of the harvesting frame 3 is also equipped with a conveying assembly for transporting the morel mushrooms swept onto it to a designated location. The conveying assembly includes two conveyor rollers 20, which are rotatably connected between the two sides of the harvesting frame 3 via bearings, and are located at both ends of the harvesting frame 3. Multiple conveyor belts 21 are driven between the two conveyor rollers 20. The conveyor belts 21 are made of food-grade rubber with anti-slip textures on the surface to prevent the morel mushrooms from slipping during transport. Gaps are left between adjacent conveyor belts 21 to help soil trapped during harvesting fall through the gaps, reducing soil adhesion to the surface of the morel mushrooms.

[0028] A central shaft 22 is rotatably connected to one outer wall of the harvesting frame 3 via bearings. The axis of the central shaft 22 is parallel to the axis of the conveying roller 20. One end of one of the conveying rollers 20 rotatably passes through the harvesting frame 3 and is fixed with a driven gear. A driving gear is fixed on the central shaft 22, and the driving gear and the driven gear mesh with each other to form a gear transmission mechanism. A driven pulley is also fixed to one end of the central shaft 22. Another driving pulley is fixed on the output shaft of the motor 19 near the driving bevel gear. This driving pulley is connected to the driven pulley on the central shaft 22 via belt transmission. When the motor 19 starts, it drives the central shaft 22 to rotate via the belt. The central shaft 22 drives the conveying roller 20 to rotate via gear transmission, which in turn drives the conveyor belt 21 to rotate cyclically, transporting the morel mushrooms swept onto the conveyor belt 21 to the other end of the harvesting frame 3. A collection frame can be placed at this end of the harvesting frame 3 to achieve centralized collection of the morel mushrooms.

[0029] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
