Description

Technical Field

[0001] This invention relates to the field of vegetable harvesting equipment technology, specifically to an electric vegetable harvesting device and its usage method. Background Technology

[0002] With the large-scale development of agricultural production and the continuous rise in labor costs, the mechanization and automation of vegetable harvesting has become an inevitable trend. At present, a variety of electric or motorized vegetable harvesting devices have appeared on the market, aiming to improve harvesting efficiency and reduce labor intensity.

[0003] In actual harvesting, existing harvesters are prone to damaging vegetables and causing them to become messy and difficult to collect after harvesting. In particular, leafy vegetables with upright stems are prone to tipping forward, tilting to the sides, or tangling and piling up after being cut due to the cutting reaction force, the forward inertia of the device, and the lack of effective support and guidance. This disorderly state of lodging will directly prevent the vegetables from being accurately and smoothly fed into the subsequent conveying mechanism, resulting in missed harvests, congestion, and even damage to the appearance of the vegetables, which seriously affects the continuity of harvesting and the uniformity of the final collection. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an electric vegetable harvesting device and its usage method, which can effectively solve the problem that vegetables become skewed during harvesting, resulting in damage to the appearance of vegetables during transportation.

[0036] Preferably, the motor drives the second transmission rod to rotate via the first transmission shaft; the first transmission shaft drives the drive wheel to rotate via the first transmission wheel and the first transmission belt; the first transmission shaft drives the second drive shaft to rotate via the third transmission wheel and the second transmission belt, thereby driving the conveyor belt to rotate; the second drive shaft drives the first drive shaft to rotate via the fifth transmission wheel and the third transmission belt, thereby driving the moving blade of the reciprocating cutter to reciprocate.

[0037] A method of using an electric vegetable harvesting device includes the following steps:

[0038] Step 1: Move the device to the work area using the walking mechanism and adjust the height of the front of the frame so that the reciprocating cutter is at the preset cutting height;

[0039] Step 2: Start the movement of the second drive rod, conveyor belt, reciprocating cutter, and traveling mechanism;

[0040] Step 3: As the device moves forward, the vegetable stalks enter the guide gap between adjacent guide plates. The guide plates gather the vegetable stalks and guide them to the cutting area of ​​the reciprocating cutter.

[0041] Step 4: Use a reciprocating cutter to sever the vegetable roots and stems;

[0042] Step 5: The teeth of the second drive rod rotate with the second drive rod, and the teeth extend into the guide gap to push the cut vegetables backward, so that they are separated from the guide plate and fall onto the conveyor belt.

[0043] Step Six: The conveyor belt transports the fallen vegetables backward, eventually dropping them into the collection box at the back.

[0044] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0045] First, by setting a guide plate with a wide upper and narrow lower guide gap, the vegetable stems can be effectively gathered and guided before cutting. Combined with the timely support of the stems by the pressure strip that moves back and forth with the blades during cutting, and the precise and timely push of the vegetables to the conveyor belt by the teeth on the second transmission rod after cutting, this design effectively overcomes the problems of vegetables tilting forward, leaning to the sides, or tangling and piling up due to inertia and reaction force after cutting. It ensures that the vegetables can enter the conveying stage in a neat and orderly manner, significantly improving the continuity of harvesting and the neatness of collection, and reducing missed harvests and damage.

[0046] Secondly, by using a single motor to simultaneously drive the walking, cutting, feeding, and conveying actions through the transmission system, the power structure and transmission chain are simplified, reducing manufacturing costs and maintenance complexity. The guide plate is made of flexible material and is equipped with elastic connectors, which can adapt to vegetable roots and stems of different diameters, making it highly versatile and avoiding damage to vegetables. The surface of the conveyor belt is equipped with anti-slip strips and soil-collecting grooves, which not only ensures the stability of the conveying but also achieves preliminary soil removal.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0060] The present invention will be further described below with reference to embodiments.

[0061] Example: Refer to Figures 1 to 6 An electric vegetable harvesting device and its method of use, comprising a frame 1 and a traveling mechanism 2, a cutting mechanism 3, and a collecting mechanism 4 mounted on the frame 1.

[0062] Specifically, the cutting mechanism 3 includes a reciprocating cutter 31, which is located at the bottom front of the frame 1 and is used to cut vegetable stems;

[0063] Multiple guide plates 32 are positioned directly above the reciprocating cutter 31, and a guide gap 321, which is wider at the top and narrower at the bottom, is formed between two adjacent guide plates 32.

[0064] The collecting mechanism 4 includes a conveyor belt 41, the front end of which extends below the rear edge of the reciprocating cutter 31 for receiving the cut vegetables.

[0065] It also includes a second transmission rod 42, which is rotatably disposed above and behind the reciprocating cutter 31. It includes the second transmission rod 42 and a plurality of teeth 421 disposed on the outer wall of the second transmission rod 42. During rotation, the teeth 421 extend into the guide gap 321 and push the cut vegetables backward toward the conveyor belt 41.

[0066] In this embodiment of the invention, the collection box 43 is disposed below the rear end of the conveyor belt 41 and is used to receive vegetables conveyed by the conveyor belt 41;

[0067] A square frame is fixedly installed inside the frame 1 at a position away from the reciprocating cutter 31 on the conveyor belt 41. The collection box 43 is slidably disposed inside the square frame. A limit frame is welded to the edge of the opening of the collection box 43 and contacts the square frame, thus being disposed below the rear end of the conveyor belt 41.

[0068] Specifically, the guide plate 32 is installed on the frame 1 through the elastic connector 322. The upper part of the guide gap 321 is used to accommodate the vegetable leaf part, and the lower part is used for the vegetable root to pass through. The guide plate 32 is made of flexible material so that the size of the guide gap 321 between adjacent guide plates 32 can be adaptively adjusted according to the diameter of the vegetable root.

[0069] It should be noted that multiple guide plates 32 are provided, and the outer wall is made of rubber. (Refer to...) Figure 2 The guide plate 32 is connected by an L-shaped frame and fixedly mounted on the frame 1 via a series of L-shaped frames connected to a straight rod. The L-shaped frames connected to the straight rod and near both ends of the straight rod are fixedly connected. A spring is installed between each L-shaped frame in the middle, so that the L-shaped frame drives the guide plate 32 to move, increasing the spacing of the guide gap 321. Furthermore, the guide gap 321, which is wider at the top and narrower at the bottom, can effectively support the vegetables after they are cut. It should be noted that, referring to... Figure 3The moving blade 311 and the fixed blade 312 are provided with notches. When the moving blade 311 and the fixed blade 312 overlap, the vegetables can enter the notches between the moving blade 311 and the fixed blade 312. When the moving blade 311 and the fixed blade 312 cross, the moving blade 311 cuts the vegetables. Each guide gap 321 is provided and corresponds one-to-one with the notches between the moving blade 311 and the fixed blade 312.

[0070] Example 2, refer to Figures 2 to 3 The reciprocating cutter 31 includes:

[0071] The moving blade 311 and the fixed blade 312 are provided. The moving blade 311 can move along the width direction of the frame 1 under the action of the first drive shaft 314. When the moving blade 311 is in an alternating layered state with the fixed blade 312, it cuts the vegetables.

[0072] The first drive shaft 314 has a reciprocating threaded groove on its outer wall and is connected to the handle of the moving blade 311 through a fixed ball bearing to drive the moving blade 311 to reciprocate.

[0073] The pressure strip 313 is fixedly installed on the upper surface of the moving blade 311 and extends along the front and rear direction of the frame 1. It reciprocates with the moving blade 311 and is used to support the vegetable stems during cutting.

[0074] The end of the tooth 421 is provided with a pushing part 422 extending toward the conveyor belt 41. The pushing part 422 is a straight rod or an arc rod, which is used to push the vegetables into the guide gap 321 when rotating.

[0075] When the tooth 421 rotates to the lowest point, there is a certain vertical distance between the pushing part 422 and the upper surface of the conveyor belt 41.

[0076] The teeth 421 are made of elastic rubber and are arranged in a circular pattern on the outer wall of the second transmission rod 42 in the number of guide gaps 321. When rotating, they pass through the guide gaps 321 to push the vegetables to move.

[0077] Multiple raised anti-slip strips 411 are evenly distributed on the surface of the conveyor belt 41. The anti-slip strips 411 extend along the width direction of the conveyor belt 41, and soil-accommodating grooves 412 are formed between adjacent anti-slip strips 411.

[0078] There is a certain gap between the collection box 43 and the conveyor belt 41. When the conveyor belt 41 transports vegetables, the soil that falls into the soil-collecting groove 412 formed between the adjacent anti-slip strips 411 will fall to the ground through the gap between the collection box 43 and the conveyor belt 41, thus preventing the soil from falling into the collection box 43.

[0079] Example 3, referring to Figures 1 to 5The first drive shaft 314, the second drive shaft 413 and the first transmission shaft 52 are located close to each other and near the motor 51, and can be driven by the same drive component. Specifically;

[0080] Walking mechanism 2 includes:

[0081] Drive wheel 21 is located at the lower front part of frame 1;

[0082] Driven wheel 22 is located at the lower rear of frame 1 and is connected to frame 1 via an existing rotary bearing;

[0083] The height adjustment component 23 is disposed between the drive wheel 21 and the frame 1;

[0084] Height adjustment component 23 includes:

[0085] The fixed bracket 231 is fixed to the front end of the frame 1 and has an arc-shaped sliding groove inside.

[0086] The movable bracket 232 slides in conjunction with the arc-shaped groove, and its lower end is rotatably connected to the axle of the drive wheel 21;

[0087] The adjusting screw 233 passes through the fixed bracket 231 and abuts against the movable bracket 232, and is used to drive the movable bracket 232 to slide in the slide groove to adjust the ground height of the front of the frame 1.

[0088] It should be noted that the fixed bracket 231 is symmetrically arranged at the front of the frame 1. By twisting the adjusting screw 233, the movable bracket 232 slides within the fixed bracket 231 to adjust the height of the frame 1. Then, by twisting the adjusting screw 233 to fix it, the front end of the frame 1 is raised. This allows for raising and cutting according to the cutting height of different vegetable roots and stems.

[0089] It also includes a powertrain assembly 5, which includes:

[0090] Motor 51 is fixed on frame 1, and its output end is connected to first drive shaft 52. First drive shaft 52 is fixedly connected to second drive rod 42.

[0091] The first transmission wheel 53 and the third transmission wheel 56 are mounted on the first transmission shaft 52;

[0092] The second transmission wheel 54 is mounted on the axle of the drive wheel 21 and is connected to the first transmission wheel 53 via the first transmission belt 55;

[0093] The second drive shaft 413 is located at the front and rear ends of the conveyor belt 41 and is used to drive the conveyor belt 41 to reciprocate and transport vegetables. Multiple second drive shafts 413 are provided and are fixedly installed in the frame 1 to mesh with the conveyor belt 41 for transmission. The outer wall is fitted with the conveyor belt 41. When the second drive shaft 413 is driven to rotate, it drives the conveyor belt 41 to rotate and drives the vegetables to move into the collection box 43.

[0094] The fourth transmission wheel 57 is mounted on the second drive shaft 413 and is connected to the third transmission wheel 56 via the second transmission belt 58;

[0095] The fifth transmission wheel 59 is mounted on the second drive shaft 413;

[0096] The sixth transmission wheel 60 is mounted on the first drive shaft 314 and is connected to the fifth transmission wheel 59 via the third transmission belt 61.

[0097] The motor 51 drives the second transmission rod 42 to rotate via the first transmission shaft 52; the first transmission shaft 52 drives the drive wheel 21 to rotate via the first transmission wheel 53 and the first transmission belt 55; the first transmission shaft 52 drives the second drive shaft 413 to rotate via the third transmission wheel 56 and the second transmission belt 58, thereby driving the conveyor belt 41 to rotate; the second drive shaft 413 drives the first drive shaft 314 to rotate via the fifth transmission wheel 59 and the third transmission belt 61, thereby driving the moving blade 311 of the reciprocating cutter 31 to reciprocate. The motor 51 is mounted on one side of the frame 1 via an external frame, and its output end passes through the external frame and is connected to the first transmission shaft 52. The first transmission shaft 52 is connected to the second transmission rod 42 and drives the gear 421 to rotate around the axis of the second transmission rod 42.

[0098] The working principle of this invention is as follows:

[0099] When this electric vegetable harvesting device is in operation, the device is first moved to the working area by the walking mechanism 2. The operator adjusts the ground clearance of the front of the frame 1 by the height adjustment component 23 according to the vegetable variety and growth condition. During adjustment, the adjusting screw 233 is rotated to make the movable support 232 slide in the arc-shaped groove of the fixed support 231. The movable support 232 swings up and down around the driven wheel 22 as the axis, thereby driving the front of the frame 1 to rise and fall, so that the reciprocating cutter 31 is at the preset cutting height.

[0100] After adjustment, start the motor 51 of the power transmission assembly 5. The first transmission shaft 52 at the output end of the motor 51 rotates, driving the second transmission rod 42 fixedly connected to it to rotate. The second transmission rod 42 begins to work. At the same time, the first transmission wheel 53 on the first transmission shaft 52 drives the second transmission wheel 54 to rotate through the first transmission belt 55. The second transmission wheel 54 drives the axle of the drive wheel 21, causing the drive wheel 21 to rotate, and the device begins to move forward. The third transmission wheel 56 on the first transmission shaft 52 drives the fourth transmission wheel through the second transmission belt 58. 57 rotates, the fourth transmission wheel 57 drives the second drive shaft 413 to rotate, the second drive shaft 413 drives the conveyor belt 41 to rotate, the fifth transmission wheel 59 on the second drive shaft 413 drives the sixth transmission wheel 60 to rotate through the third transmission belt 61, the sixth transmission wheel 60 drives the first drive shaft 314 to rotate, the first drive shaft 314 drives the moving blade 311 to perform high-speed reciprocating motion through the reciprocating thread groove and fixed ball on the outer wall, the moving blade 311 and the fixed blade 312 are stacked in an alternating manner to form shearing, and the reciprocating cutter 31 begins the cutting operation;

[0101] During the forward movement of the device, the vegetable stalks first enter the guide gap 321 formed between adjacent guide plates 32. The guide gap 321 is trumpet-shaped, wider at the top and narrower at the bottom. The wider part at the top is used to accommodate the vegetable leaves, and the narrower part at the bottom is for the vegetable roots to pass through. The guide plates 32 are made of flexible material and are installed on the frame 1 through elastic connectors 322. When vegetable roots of different diameters pass through, the size of the guide gap 321 can be adjusted adaptively to ensure that the vegetables are effectively gathered and to avoid damaging the vegetables.

[0102] As the device continues to move forward, the vegetable stalks gathered by the guide gap 321 are pushed to the cutting area of ​​the reciprocating cutter 31. At this time, the pressure strip 313, which is fixedly installed on the upper surface of the moving blade 311, moves in a high-speed reciprocating motion along with the moving blade 311. The pressure strip 313 extends along the front and rear direction of the frame 1 and contacts the upper part of the vegetable stalk at the moment of cutting. It supports the vegetable stalk through the lateral friction force generated by the high-frequency reciprocating motion, preventing it from tilting forward when subjected to shearing force.

[0103] When the moving blade 311 and the fixed blade 312 complete the cutting, the vegetable root is cut off. At this time, the upper part of the vegetable is still restricted within the guide gap 321, maintaining an upright position, neither falling forward nor tilting to the left or right.

[0104] The second transmission rod 42 rotates continuously, and multiple teeth 421 installed on the outer wall of the second transmission rod 42 rotate accordingly. The teeth 421 are made of flexible material and have a pushing part 422 extending towards the conveyor belt 41 at the end. The pushing part 422 is a straight rod or an arc rod. When the teeth 421 rotate to the lowest point, the pushing part 422 extends into the guide gap 321 and contacts the cut vegetable stem. The pushing part 422 applies a backward pushing force, causing the upper part of the vegetable to detach from the guide gap 321 of the guide plate 32. The vegetable is forced to fall backward from an upright position.

[0105] At this time, the front end of the conveyor belt 41 extends precisely to below the rear edge of the reciprocating cutter 31. The vegetables that are knocked down fall directly onto the conveyor belt 41. Multiple raised anti-slip strips 411 are evenly distributed on the surface of the conveyor belt 41. The anti-slip strips 411 extend along the width direction of the conveyor belt 41. Soil-holding grooves 412 are formed between adjacent anti-slip strips 411. The vegetable stems sink into the soil-holding grooves 412 between the anti-slip strips 411, increasing friction and preventing slippage. At the same time, the soil carried by the vegetables is shaken off during the conveying process and falls to the ground from the edge of the soil-holding grooves 412.

[0106] The conveyor belt 41 operates continuously, transporting the fallen vegetables to the rear and upward, and finally they fall into the collection box 43 at the rear. The collection box 43 has a detachable or flip-up structure, which makes it easy to unload the harvested vegetables in a concentrated manner.

[0107] Throughout the entire operation, the power of the motor 51 is simultaneously distributed to the walking mechanism 2, the cutting mechanism 3, and the collecting mechanism 4 via the first transmission shaft 52, enabling coordinated operation of the drive wheel 21 moving forward, the reciprocating cutter 31 cutting, the guide plate 32 knocking down, and the conveyor belt 41 transporting. When the teeth 421 of the guide plate 32 rotate to the lowest point and extend into the guide gap 321, it is exactly the moment when the reciprocating cutter 31 completes the cutting. The operating speed of the conveyor belt 41 is coordinated with the forward speed of the device to ensure that the knocked-down vegetables can fall smoothly onto the conveyor belt 41 and be transported away in a timely manner.

[0108] A method of using an electric vegetable harvesting device includes the following steps:

[0109] Step 1: Move the device to the work area using the walking mechanism 2, and adjust the height of the front of the frame 1 so that the reciprocating cutter 31 is at the preset cutting height;

[0110] Step 2: Start the movement of the second transmission rod 42, the conveyor belt 41, the reciprocating cutter 31, and the traveling mechanism 2;

[0111] Step 3: During the forward movement of the device, the vegetable stalks enter the guide gap 321 between adjacent guide plates 32. The guide plates 32 gather the vegetable stalks and guide them to the cutting area of ​​the reciprocating cutter 31.

[0112] Step 4: Use the reciprocating cutter 31 to cut the vegetable roots and stems;

[0113] Step 5: The teeth 421 of the second transmission rod 42 rotate with the second transmission rod 42. The teeth 421 extend into the guide gap 321 and push the cut vegetables backward, so that they are separated from the guide plate 32 and fall onto the conveyor belt 41.

[0114] Step Six: The conveyor belt 41 transports the fallen vegetables backward, eventually dropping them into the collection box 43 at the rear.

[0115] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
