However, existing leek harvesters suffer from poor harvesting results when encountering varying planting densities in each row of leeks or different row spacings between multiple rows, and they also do not consider the issue of automatic bundling and collection after harvesting. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a self-propelled double-row harvester to improve harvesting efficiency and reduce the production cost of chives. The solution is as follows:

[0020] The fourth drive device is mounted on the baling and collecting bracket and connected to one end of the main baling frame assembly. The main baling frame assembly is connected to the secondary baling frame assembly through a transmission mechanism.

[0026] Compared with the prior art, the advantages of the present invention are as follows:

[0027] The harvesting and conveying device of this invention gathers the chives to the cutting position using a rake, and then gathers them between the two clamping belts of the clamping and conveying mechanism, achieving rapid and neat cutting and conveying of the chives. A screw spring assembly is set up to adjust the position of the tension wheel assembly to adjust the spacing of the clamping belts, so as to adapt to the clamping and conveying requirements after harvesting chives with different planting densities and row spacings.

The main and secondary baling frame assemblies are configured as either movable or fixed main and secondary baling frames that can be rotated. The chives falling from the belt conveyor are fed into the baling frames in a flat and orderly manner. An electric push rod sends the baling frames into the baling machine for baling. Then, a rotary motor drives the main shaft of the transmission device to rotate. The main shaft drives the movable main and secondary baling frames to rotate through the first and second belt drives, so that the baled chives fall into the vegetable box.

[0029] This invention includes components such as a magnetic sensor and a front wheel electric push rod. The magnetic sensor can collect ground height information through the weight of the caster wheel, which is then fed back to the control box.

Detailed Implementation

[0047] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0048] like Figure 1As shown, this invention proposes a self-propelled double-row harvester, including a harvester body, a transverse conveying device 300 at the top of the harvester body, a harvesting conveying device 100 at the front end of the harvester body, and a baling and collecting device 200 on one side of the harvester body. When the harvester is working, chives are harvested and clamped by the harvesting conveying device 100 and transported to the transverse conveying device 300. After accumulating a certain amount of chives, the transverse conveying device 300 transports them to the baling and collecting device 200. The baling and collecting device 200 bales the chives and stores them in a vegetable bin 230. This invention can meet the clamping and transport requirements after harvesting chives with different planting densities and row spacings, and can automatically bale and collect chives with different row spacings after harvesting, improving harvesting efficiency and reducing chive production costs.

[0049] Specifically, such as Figure 2 As shown, the main body of the harvester is configured as a frame structure 400, which is welded from steel profiles. A fixed base 118 and a movable base 119 are mounted on the front end of the frame structure 400. The fixed base 118 is welded to the frame structure 400, and the movable base 119 is slidably connected to the frame structure 400 via a sliding assembly 1191. The frame structure 400 is bolted to the main body of the first drive mechanism, and the movable end of the first drive mechanism is connected to the movable base 119 for driving its linear movement. In this embodiment, the first drive mechanism is an electric push rod, and the piston rod of the electric push rod is bolted to the movable base 119. A clamping and conveying mechanism 110 is installed on the fixed base 118 and the movable base 119 respectively. The two clamping and conveying mechanisms 110 are arranged in parallel. The first driving device 1192 drives the movable base 119 to move, changing the distance between the two clamping and conveying mechanisms 110. In this way, the distance between the two clamping and conveying mechanisms 110 can be adjusted in real time according to the size of the spacing between the two rows of chives, which has strong applicability.

[0050] A transverse conveying device 300 is provided on the upper part of the frame structure 400, and a bundling and collecting bracket 210 of the bundling and collecting device 200 is welded to the end of the frame structure 400 near the conveying direction of the transverse conveying device 300.

[0051] A front wheel electric push rod 410 is installed at the front end of the frame structure 400, and at each end of the fixed base 118 and the movable base 119. The front wheel electric push rod 410 is connected to the front wheel 420 through a front wheel bracket. The front wheel electric push rod controls the vertical height of the front wheel 420, thereby adjusting the height of the frame structure 400. In this embodiment, as shown... Figure 2As shown, the upper end of the front wheel bracket (not shown in the figure) is fixedly connected to the front wheel electric push rod 410, and the lower end of the front wheel bracket is connected to the front wheel 420. The middle part of the front wheel bracket is also hinged to the frame structure 400. The front wheel electric push rod 410 extends and retracts to adjust the angle of the front wheel bracket, thereby realizing the vertical height adjustment of the front wheel 420, and thus realizing the height adjustment of the frame structure 400 relative to the ground. When the height of the frame structure 400 changes, the height of the harvesting and conveying device 100 installed on the frame structure 400 changes, and the height of the cutter 122 also changes. The rear axle 430 is installed at the bottom of the frame structure 400, and the two ends of the rear axle 430 are connected to the rear wheels 440. The battery 470 and the electrical control box 460 are installed at the rear of the frame structure 400. The battery 470 serves as a power source, providing strong and stable power to the entire machine through the rear axle 430. The electrical control box 460 serves as the control center, allowing the operator to conveniently manually adjust the forward speed, cutter 122 height, conveying speed, clamping conveyor mechanism 110, and cutter 122 spacing of the double-row leek harvester. A height detection device 450 is also installed at the bottom of the frame structure 400 near the front wheel 420. The height detection device 450 includes a magnetic sensor 451 and a caster wheel 452. The weight of the caster wheel 452 causes the magnetic sensor 451 to collect ground height information, which is then fed back to the electrical control box 460. The electrical control box 460 then controls the front wheel electric push rod 410 to control the vertical height of the front wheel 420, thereby adjusting the height of the cutting mechanism 120. This ensures that the leeks are cut evenly even on uneven terrain.

[0052] The main components are described below.

[0053] 1. Harvesting and conveying device 100

[0054] like Figures 3-6 As shown, the harvesting and conveying device 100 includes two clamping and conveying mechanisms 110, two cutting devices, a fixed base 118, and a movable base 119. A cutting device is installed at the lower part of one clamping and conveying mechanism 110. The fixed base 118 is fixedly connected to the main body of the harvester, and the movable base 119 is slidably connected to the main body of the harvester. The two clamping and conveying mechanisms 110 are installed one-to-one on the top of the fixed base 118 and the movable base 119.

[0055] Specifically, the clamping and conveying mechanism 110 includes two parallel conveying components. For example... Figure 7 As shown, the conveying components include a belt conveyor bracket 117, a picker 111, a belt support hub 114, a clamping belt 112, a second drive device 113, and an adjustment device for adjusting the tension of the clamping belt 112.

[0056] Specifically, the reel 111 is connected to one end of the belt conveyor bracket 117 by screws. The belt conveyor bracket 117 includes two parallel support plates 1171 and a support column 1172 located between the support plates 1171. The belt support hub 114 is hinged at both ends to the upper and lower support plates 1171 respectively.

[0057] There are two belt support hubs 114, which are installed at both ends of the belt cable assembly bracket 117. The adjustment device is located between the belt support hubs 114 and connected to the belt cable assembly bracket 117. The clamping belt 112 is wound around the belt support hub 114. The second drive device 113 is connected to one belt support hub 114 to drive the clamping belt 112 to rotate along the belt support hub 114 and the adjustment device. This allows for adaptive adjustment according to the planting density of each row of chives.

[0058] In this embodiment, the second drive device 113 is a DC geared motor 311. The DC geared motor 311 is fixedly installed on the support plate 1171 of the belt assembly bracket 117. The output shaft of the DC geared motor 311 is connected to one end of the belt support hub 114 to drive the belt support hub 114 to rotate synchronously, thereby driving the clamping belt 112 to rotate.

[0059] Specifically, such as Figure 8 As shown, the adjusting device includes two sets of tension wheel assemblies 116 and a screw spring assembly 115. The tension wheel assembly 116 is connected to the belt conveyor bracket 117 and located between two belt support hubs 114. The tension wheel assembly 116 includes two support wheels 1611, with connecting members 1162 connected to both ends of each support wheel 1611. These connecting members 1162 are hinged to the support plate 1171 of the belt conveyor bracket 117. The screw spring assembly 115 is connected to the support plate 1171 and one support wheel 1611 respectively. The angle between the tension wheel assembly 116 and the belt conveyor bracket 117 is changed by adjusting the spring force of the screw spring assembly 115. In this embodiment, the screw spring assembly 115 is a purchased component. Rotating the adjusting screw compresses or releases the spring force, achieving the adjusting effect. The tension wheel assembly 116 is hinged to the nut post of the screw spring assembly 115.

[0060] The middle part of the connector 1162 is hinged to the support plate 1171, and both ends of the connector 1162 are respectively hinged to the support wheel 1611. In this embodiment, the connector 1162 is a V-shaped plate, the tip of the V-shaped plate is hinged to the support plate 1171 by a pin, and the two rods at the open end of the V-shaped plate are respectively connected to the ends of the support wheel 1611.

[0061] For better adjustment, the screw spring assembly 115 located at the lower part of the conveying component and the screw spring assembly 115 located at the upper part of the conveying component are not on the same side; the screw spring assembly 115 located at the lower part of the conveying component is arranged opposite to the screw spring assembly 115 used in pairs at the lower part of the conveying component, and the screw spring assembly 115 located at the upper part of the conveying component is arranged facing each other.

[0062] like Figure 9 As shown, the cutting mechanism 120 is located behind the reel 111 and includes a cutting bracket 121, a cutter 122, and a third drive device 124. The cutting bracket 121 is fixedly connected to the belt conveyor bracket 117 by screws. The cutter 122 is located at the bottom of the cutter 122 bracket. The third drive device 124 is fixed to the cutter 122 bracket by bolts. In this embodiment, the third drive device 124 is a motor. The motor is connected to the cutter 122 through a coupling and is used to drive the cutter 122 to rotate. The coupling transmits the power of the motor in the horizontal direction to the cutter in the vertical direction.

[0063] The harvesting and conveying device 100 of this invention differs from existing harvester conveying devices. Existing harvesters require pre-adjustment of the relative height between the cutter and the ridge surface, and cannot automatically adjust the cutter height based on ridge height variations during harvesting. Existing clamping and conveying mechanisms use a torsion belt, resulting in long clamping and conveying distances and larger harvester sizes. Existing double-row harvester conveying devices are fixedly installed and cannot automatically adjust row spacing, reducing equipment adaptability. The harvester of this invention has the advantages of compact structure, adaptive cutter height adjustment, and strong agronomic adaptability, making it particularly suitable for small-plot operations in greenhouse facilities.

[0064] The working process of the harvesting and conveying device 100:

[0065] As the harvester moves forward, the reel 111 gathers the chives to the cutter 122, ensuring the chives are neatly cut. During the harvester's movement, the harvested chives are gathered and guided to the clamping conveyor 110. The second drive unit 113 provides power to the conveyor belt, driving the belt support hub 114 to rotate, which in turn rotates the clamping belt 112, smoothly guiding the harvested chives into the next process. Before the harvester starts operating, the distance between the support wheels 1161 of the tension wheel assembly 116 can be changed by adjusting the stroke of the screw on the screw spring assembly 115 on the nut column, thereby controlling the width of the clamping belt and changing the clamping degree. This allows for adaptive adjustment based on the planting density of each row of chives. When a change in the planting gap between adjacent rows of chives is detected, the first drive unit 1192 drives the moving base 119 to a suitable position, achieving adaptive adjustment based on the row spacing between multiple rows of chives.

[0066] 2. Horizontal conveyor device 300

[0067] like Figure 10 As shown, the transverse conveying device 300 includes a belt conveyor 310 and a conveyor baffle 320. The conveyor baffle 320 is located on the upper part of the transmission belt 313 of the belt conveyor 310 near one end of the baling and collecting device 200, and is hinged to the frame. The belt conveyor 310 is prior art and includes a belt rotating roller, a transmission belt wound around the belt rotating roller, a motor 311 for driving the belt rotating roller, and a motor reducer 312. The conveyor baffle 320 is made of a lightweight material, such as a rubber sheet or a plastic sheet. When a certain amount of chives accumulates on the belt conveyor 310, the chives on the transmission belt 313 push the conveyor baffle 320 to rotate and open, and the chives fall into the main baling frame assembly 240 and the secondary baling frame assembly 250 of the baling and collecting device 200.

[0068] 3. Bundling and collection device 200

[0069] like Figures 11-15 As shown, the baling and collecting device 200 includes a baling and collecting bracket 210, a baler 220, a vegetable box 230, a main baling frame assembly 240, a secondary baling frame assembly 250, a fourth drive device 260, and a fifth drive device 270.

[0070] In this embodiment, the baling and collecting bracket 210 is welded to the frame structure 400, and the baler 220 and the baling and collecting bracket 210 are bolted together by connector 1162. The vegetable box 230 is detachably connected to the baling and collecting bracket 210 to facilitate the disassembly of the vegetable box 230.

[0071] The main baling frame assembly 240 and the auxiliary baling frame assembly 250 are used as a whole, serving two purposes: first, to receive the harvested chives from the previous process of the combine harvester; and second, to bale the chives. A gap is formed between the main baling frame assembly 240 and the auxiliary baling frame assembly 250 to facilitate baling the chives. When the main baling frame assembly 240 and the auxiliary baling frame assembly 250 move synchronously to the baler 220, with the gap corresponding to the working area of ​​the baler 220, the baler 220 begins baling the chives.

[0072] The main bundling frame assembly 240 is located on the upper part of the vegetable box 230, and includes a fixed main bundling frame 241 and a movable main bundling frame 242 rotatably connected to the fixed main bundling frame 241. The secondary bundling frame assembly 250 is located to one side of the main bundling frame assembly 240, and a gap exists between the main bundling frame assembly 240 and the primary bundling frame assembly 240. The secondary bundling frame assembly 250 includes a fixed secondary bundling frame 251 and a movable secondary bundling frame 252 rotatably connected to the fixed secondary bundling frame 251. This gap is used for subsequent bundling of the chives by the baling machine 220.

[0073] The fourth drive device 260 is mounted on the baling and collecting bracket 210 and connected to one end of the main baling frame assembly 240. The main baling frame assembly 240 is connected to the auxiliary baling frame assembly 250 via a transmission mechanism 280, and is used to drive the main baling frame assembly 240 and the auxiliary baling frame assembly 250 to move synchronously back and forth. In this embodiment, the first drive device 1192 is an electric push rod.

[0074] The fifth drive device 270 is mounted on the baling and collecting bracket 210 and is used to drive the movable main baling frame 242 and the movable auxiliary baling frame 252 to rotate synchronously. After baling is completed, when the fourth drive device 260 returns to its shortest stroke, the fifth drive device 270 is connected to the movable main baling frame 242 and the movable auxiliary baling frame 252 through the transmission mechanism 280 to drive the movable main baling frame 242 and the movable auxiliary baling frame 252 to rotate synchronously. In this embodiment, the fifth drive device 270 is a rotary cylinder, which is a purchased component and achieves a 90-degree rotation angle.

[0075] Specifically, the transmission mechanism 280 includes a main shaft 281 selectively connected to the fifth drive device 270, a first belt drive 282, a second belt drive 283, a first auxiliary shaft 284, and a second auxiliary shaft 285. The main shaft 281 passes sequentially through the drive wheels of the first belt drive 282 and the second belt drive 283. One end of the first auxiliary shaft 284 is connected to the driven wheel of the first belt drive 282, and the other end is connected to the movable main baling frame 242. One end of the second auxiliary shaft 285 is connected to the driven wheel of the second belt drive 283, and the other end is connected to the movable auxiliary baling frame 252. The electric push rod is sequentially connected to the first belt drive 282 and the fixed main baling frame 241. The baling and collecting device 200 also includes a support shaft 290. One end of the support shaft 290 is connected to a bearing support seat 291, which is fixedly mounted on a bracket by bolts. The other end of the support shaft 290 is sequentially connected to the second belt drive 283 and the fixed auxiliary baling frame 251.

[0076] Specifically, the vegetable box 230 and the bundling and collection bracket 210 are connected by a plug-in connection, and the vegetable box 230 and the bundling and collection bracket 210 are respectively provided with mutually cooperating groove strips 211 and protruding strips 231.

[0077] The baler 220 is a purchased component. The baler 220 is equipped with a photoelectric sensor. When vegetables are in the working area of ​​the baler 220, the photoelectric sensor sends a signal to the internal controller of the baler 220, and the baler 220 performs the baling operation.

[0078] More specifically, a main shaft 281 bracket is fixed to the bundling and collection bracket 210 by bolts. The main shaft 281 bracket is a bearing support seat 291 used to support the main shaft 281, and the main shaft 281 can rotate relative to the main shaft 281 bracket. The left end of the main shaft 281 is fixed with the drive wheel of the second belt drive 283 via a key shaft. The drive wheel of the second belt drive 283 drives the driven wheel to rotate via the synchronous belt of the second belt drive 283. The driven wheel drives the movable auxiliary bundling frame 252 to rotate. The movable auxiliary bundling frame 252 is attached with an induction sponge ring 253. The movable auxiliary bundling frame 252 is connected to the driven wheel of the second belt drive 283 via a key shaft. The second cover is fixed to the auxiliary bundling frame 251 by bolts. The right end of the main shaft 281 is fixed with the drive wheel of the first belt drive 282 via a key shaft. The drive wheel of the first belt drive 282 is installed in the first cover. The drive wheel of the first belt drive 282 drives the driven wheel to rotate via the synchronous belt of the first belt drive 282. The driven wheel drives the movable main bundling frame 242 to rotate. The movable main bundling frame 242 is fixed in the first cover by a key connection to the driven wheel of the first belt drive 282. The first cover is fixed to the main bundling frame 241 by bolts. A rotary cylinder base is fixedly installed on the baling and collecting bracket 210. The rotary cylinder base supports the rotary cylinder and the electric push rod. The movable end of the electric push rod is fixedly connected to the first cover. The rotary cylinder is selectively connected to the right end of the main shaft 281. The vegetable box 230 is detachable and is used to hold the baled chives. The electric push rod pushes the first cover to perform linear reciprocating motion. The first cover drives the fixed main baling frame 241, the movable main baling frame 242, and the main and driven wheels of the first belt drive 282 to perform linear reciprocating motion. The drive wheel of the first belt drive 282 is connected to the main shaft 281 through a key, thereby driving the main shaft 281 to perform reciprocating linear motion. The main shaft 281 then drives the second cover, the movable auxiliary baling frame 252, and the fixed auxiliary baling frame 251 to perform linear reciprocating motion. When the electric push rod pushes the main baling frame assembly 240 and the auxiliary baling frame assembly 250 to the baling position of the baler 220 (refer to...), the baling cylinder base supports the rotary cylinder and the electric push rod to perform linear reciprocating motion. Figure 11 , 12 The sensing sponge ring 253 on the active secondary baling frame 252 continuously triggers the photoelectric sensor on the baler 220, causing the baler 220 to bale the chives. After baling, the baler 220 returns the baling frame to its initial position (see reference). Figure 13 , 14During this process, the sensing sponge ring 253 moves away from the photoelectric sensor to avoid secondary triggering. When the leeks are bundled and the bundling frame returns to its initial position, the rotary cylinder, through a coupling, engages with the shaft hole of the main shaft 281 to rotate the main shaft 281. The main shaft 281, through the synchronous belt of the first belt drive 282, drives the driven wheel of the first belt drive 282 on the movable main bundling frame 242 to rotate. The rotation of the main shaft 281 is transmitted through the driven wheel of the second belt drive 283, causing the movable auxiliary bundling frame 252 to rotate. The rotary cylinder, through the main shaft 281 and the two first and second belt drives, drives the movable main bundling frame 242 and the movable auxiliary bundling frame 252 to rotate synchronously (see...). Figure 15 The rotary cylinder rotates at a 90-degree angle. After releasing the bundled chives, the rotary cylinder returns to its initial position.

[0079] like Figure 14 As shown, the gap between the secondary baling frame assembly 250 and the main baling frame assembly 240 is represented by d, and the size of the gap d is approximately the same as the working area width of the baler 220.

[0080] Unlike existing baling and collecting devices that require manual assistance and thus have limited efficiency improvements, the baling and collecting device of this invention has automatic baling and collecting functions, which improves the harvesting efficiency and automation level of the equipment.

[0081] The working process of the baling and collecting device 200:

[0082] Initial position: Both the main bundling frame assembly 240 and the auxiliary bundling frame assembly 250 are located on top of the vegetable box 230. At this time, the electric push rod retracts, the rotary cylinder is connected to the main shaft 281, and the rotary cylinder is in a non-working state. Bundling position: The electric push rod extends to drive the main bundling frame assembly 240 and the auxiliary bundling frame assembly 250 to move towards the baler 220. The main shaft 281 disengages from the rotary cylinder. When the gap corresponds to the working area of ​​the baler 220, the baler 220 starts working. Returning to the initial position, the unloading action is performed. The electric push rod retracts, the main shaft 281 is connected to the rotary cylinder, the rotary cylinder starts working, and the rotation of the rotary cylinder drives the movable main bundling frame 242 and the movable auxiliary bundling frame 252 to rotate synchronously. The bundled chives are unloaded into the vegetable box 230. When the vegetable box 230 is full, pull out the vegetable box 230 to remove the chives for transfer.

[0083] The self-propelled double-row harvester of the present invention, through the cooperation of the above-mentioned components, enables the self-propelled double-row harvester of the present invention to make adaptive adjustments according to different planting densities of chives, different planting gaps between multiple rows of chives, and different harvesting terrains, thereby effectively improving the harvesting effect; and after harvesting, it can bale and collect in real time, greatly reducing labor intensity.

[0084] The working process of the self-propelled double-row harvester of the present invention is as follows:

[0085] First, the self-propelled double-row harvester is started and moves forward. The reel 111 gathers the chives to the cutter 122, ensuring that the chives can be cut neatly. As the harvester moves forward, the harvested chives are gathered to the clamping and conveying mechanism 110. The second drive device 113 (micro DC geared motor) drives the rear belt support hub 114 to rotate, thereby driving the clamping belt 112 to smoothly transport the harvested chives to the rear conveyor belt. The width between the clamping belts 112 can be adjusted by adjusting the screw spring assembly 115 to adapt to the clamping and conveying needs of chives with different planting densities and row spacings after harvesting. The two sets of clamping and conveying mechanisms 110 can be controlled by the electrical control box 460 to extend and retract the first drive device 1192 to control the movement of the moving base 119, thereby changing the distance between the clamping and conveying mechanisms 110 to achieve the purpose of harvesting chives with different row spacings. The weight of the casters 452 causes the magnetic sensor 451 to collect height data from the ground, measure the height for positioning, and control the electric push rod 410 of the front wheel to adjust the height of the cutting mechanism 120. The belt conveyor 310 realizes the continuous conveying of chives. The conveyor baffle 320 ensures that the chives fall flat and orderly into the split bundling frame during the conveying process. The fourth drive device 260, i.e., the electric push rod, synchronously sends the split bundling frame, i.e., the main bundling frame assembly 240 and the auxiliary bundling frame assembly 250, to the top of the bundling machine 220 for bundling. After bundling, it returns to the starting point. Then, the fifth drive device 270, i.e., the rotary motor, drives the first and second belt drives to rotate synchronously, which in turn drives the movable main bundling frame 242 and the movable auxiliary bundling frame 252 to rotate synchronously, so that the bundled chives fall into the vegetable box 230. The row spacing between chives can be adjusted by driving the moving base 119 to move via the first driving device 1192 to accommodate different planting row spacings during harvesting. The clamping width between the same clamping and conveying mechanisms 110 can be adjusted by adjusting the screw spring assembly 115 to meet the clamping and conveying needs after harvesting chives with different planting densities and row spacings.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
