Description

Technical Field

[0001] This utility model belongs to the field of leek harvesting technology and green prevention and control of leek diseases and pests, specifically involving an integrated leek harvesting machine. Background Technology

[0002] Chives are rich in vitamins and nutrients and are loved by many consumers. However, chives are also among the agricultural products in my country with the highest frequency of pesticide residue exceeding standards, indicating the most serious and prominent quality and safety issues. The cause of this problem is a pest called the chive maggot (Chive maggot), a devastating pest that can reduce yields by 40%-60%. The irrational use of pesticides to control this pest is the root cause of high pesticide residues in chives.

[0003] Employing green pest control methods can effectively address the problem of high pesticide residues in chives. Related studies have shown that timely mulching and soil compaction after chive harvesting utilizes high temperatures to effectively kill chive maggot eggs, larvae, pupae, and adults, as well as thrips, aphids, and other pests. Furthermore, wood ash, rich in potassium, can be used as a base fertilizer to adjust soil pH. Additionally, wood ash itself has strong bactericidal and disinfectant properties, killing chive maggots and other pest eggs, and can also be used as a green pest control method.

[0004] However, the harvesting of chives still largely relies on manual labor, with a relatively low level of mechanization. Although some chive harvesters have appeared on the domestic and international markets, the harvesting effect is not ideal, and many problems still exist in key areas such as movement and conveying. Moreover, mulching and spreading ash also largely depend on manual labor, affecting production efficiency and consuming a large amount of human resources, thus preventing the large-scale promotion of green methods for controlling chive maggots. Utility Model Content

[0005] This utility model provides an integrated leek harvesting machine, which aims to solve the problem that the leek harvesting, ash spreading and mulching work in the prior art still need to be done manually, resulting in waste of human resources and low efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a leek harvester, including: a machine body, and a harvesting device, an ash spreading device, a film covering device and a walking device installed on the machine body;

[0008] The harvesting device includes a gathering component, a blade component, and a conveying component; the chives are gathered by the gathering component and then cut by the blade component, and the cut chives are conveyed to the rear end of the machine body and discharged through the conveying component.

[0009] The ash spreading device includes an ash storage bin, an ash spreading bin, a sweeping impeller rotatably disposed in the ash spreading bin, and a conveying pipe disposed between the ash storage bin and the ash spreading bin and connecting the ash storage bin and the ash spreading bin; the ash spreading bin is provided with an ash outlet; the wood ash in the ash storage bin enters the ash spreading bin through the conveying pipe, and is discharged to the ground through the ash outlet under the rotation of the sweeping impeller;

[0010] The film covering device includes a first soil-digging shovel, a second soil-digging shovel, a roll for installing the film, and a pressure roller; the initial end of the film is located at the lower end of the pressure roller; as the machine moves, the first soil-digging shovel digs the soil on the ground to form trenches, the pressure roller covers the film on the ground, and the edge of the film is located in the trenches; the second soil-digging shovel digs the soil on the ground back into the trenches and presses it at the edge of the film.

[0011] The walking device includes a wheel assembly for driving the machine body to move.

[0012] A further embodiment: the blade assembly includes a blade holder and a blade disposed on the blade holder and rotating relative to the blade holder; the blade holder is disposed on the machine body via an L-shaped mounting member;

[0013] The L-shaped mounting component has a height adjustment groove on its side wall, and a first bolt assembly slides through the height adjustment groove; the L-shaped mounting component is fastened to the machine body by the first bolt assembly.

[0014] The bottom wall of the L-shaped mounting component is provided with an angle adjustment groove; a second bolt assembly is slidably inserted in the angle adjustment groove; the L-shaped mounting component is fastened to the tool holder by the second bolt assembly.

[0015] Based on the above solution, the angle and height of the blade can be finely adjusted by the height adjustment groove and angle adjustment groove on the L-shaped mounting piece, thereby adjusting the stubble height of the chives and improving the flexibility when cutting chives.

[0016] A further embodiment: The conveying assembly includes two sets of conveyor belt assemblies; each set of conveyor belt assemblies includes a drive wheel horizontally arranged at the rear end of the machine body, a driven wheel vertically arranged at the front end of the machine body, and a conveyor belt arranged between the drive wheel and the driven wheel; the two conveyor belts are arranged in parallel, and a clamping channel for conveying chives is formed between the two conveyor belts.

[0017] Based on the above design, the driven wheel is vertically positioned at the front end of the machine body, and the driving and driven wheels are horizontally positioned at the rear end of the machine body, enabling the chives to be conveyed from vertical to horizontal. Furthermore, the clamping channel formed between the two conveyor belts keeps the chives stable during conveying, preventing them from scattering or falling during transport.

[0018] A further embodiment: the harvesting device further includes a drive assembly for driving the conveying assembly; the drive assembly includes a drive motor, a first sprocket, a second sprocket, a third sprocket, and a chain; the first sprocket is sleeved on the output shaft of the drive motor, and the second sprocket and the third sprocket are respectively connected to the two drive wheels one-to-one;

[0019] The chain is wrapped around the outside of the first and second sprockets in sequence; the third sprocket engages with the outside of the chain.

[0020] Based on the above scheme, the drive motor drives the first sprocket through the output shaft, and then transmits power to the second sprocket and the third sprocket through the chain. Since the second sprocket and the third sprocket are engaged with the chain at opposite positions, the two drive wheels operate synchronously in opposite directions, thereby ensuring the stable operation of the two conveyor belts.

[0021] A further embodiment: The retracting assembly includes two guide plates, with a retracting opening formed between the two guide plates. The retracting opening gradually narrows from front to back, and the rear end of the retracting opening is located close to the driven wheel.

[0022] Based on the above solution, the two guide plates form a gradually narrowing opening, which can effectively gather and collect large pieces of chives together, so that they can be cut by the blade, thereby improving the cutting efficiency of chives.

[0023] A further embodiment: the ash-spreading bin is mounted on the machine body via a support frame, and the ash outlet faces the ground; an impeller motor is provided at the bottom of the support frame; the output shaft of the impeller motor passes through the support frame and the ash-spreading bin in sequence and is connected to the ash-sweeping impeller.

[0024] Based on the above scheme, the ash sweeping impeller in the ash spreading bin is rotated so that the wood ash in the ash spreading bin is evenly sprayed out from the ash outlet.

[0025] A further embodiment: the dust-sweeping impeller includes a circular tray, on which several paddles are arranged around the center of the circular tray; the output shaft of the impeller motor passes through the center of the circular tray.

[0026] A further embodiment: The wheel assembly includes four wheels rotatably mounted on the bottom of the machine body, with the four wheels located on the left and right sides of the front and rear ends of the machine body, respectively; each wheel is connected to a wheel motor; the impeller motor is linked to the four wheel motors, and the dust-sweeping impeller rotates in sync with the four wheels.

[0027] Based on the above scheme, each of the four wheels is independently driven by its own wheel motor, resulting in a small turning radius and simple control. Furthermore, the impeller motor is linked to the four wheel motors, and the sweeping impeller rotates in sync with the four wheels. This ensures that when the machine's forward speed is high, the ash output from the ash-spreading chamber is large; when the machine's forward speed is slow, the ash output from the ash-spreading chamber is small, preventing uneven ash distribution to the leek stubble due to varying machine speeds.

[0028] A further embodiment: The film covering device further includes two sets of film covering components respectively disposed on the left and right sides of the machine body; each set of film covering components includes a film covering bracket, a first soil-removing shovel, a pressure roller and a second soil-removing shovel; the first soil-removing shovel, the pressure roller and the second soil-removing shovel are arranged sequentially from front to back on the film covering bracket, and the groove formed by the pressure roller and the first soil-removing shovel is on the same straight line;

[0029] The roll is disposed between the two film-coating supports, and the roll is located in front of the pressure roller and behind the ash outlet.

[0030] Based on the above scheme, the first shovel, the pressure roller, and the second shovel are arranged in sequence to form a reasonable film covering process. In addition, the trench formed by the pressure roller and the first shovel is on the same straight line, which ensures that the edge of the film below the pressure roller is exactly within the trench, making it convenient for the second shovel to press the soil onto the edge of the film.

[0031] A further embodiment: both the first and second soil-removing shovels are inclined relative to the film-covering support; the first soil-removing shovel is inclined from front to back towards the outside of the film-covering support, and the second soil-removing shovel is inclined from front to back towards the inside of the film-covering support.

[0032] Based on the above scheme, the first and second shovels are tilted in opposite directions, so that the first shovel first removes the soil to make room for the film to be laid, and the second shovel then presses down the soil to complete the film covering work.

[0033] The beneficial effects of this utility model are as follows:

[0034] This utility model includes a harvesting device, an ash-spreading device, a mulching device, and a walking device. The harvesting device gathers the chives using a gathering component, which then cuts them using a blade assembly. The cut chives are conveyed to the rear of the machine body via a conveying component and discharged, completing the automatic harvesting of the chives. The ash-spreading device uses the rotation of a sweeping impeller in the ash storage bin to spray wood ash from the ash outlet onto the chive stubble on the ground, automatically completing the ash-spreading process. The mulching device uses a first shovel to create trenches in the ground, a pressure roller to cover the ground with a film, with the edge of the film located within the trenches, and a second shovel to push the soil back into the trenches and press it against the edge of the film, automatically completing the mulching process.

[0035] This utility model discloses an integrated leek harvesting machine that can automatically complete the harvesting, spreading of wood ash, and mulching of leeks in one go, reducing reliance on manual labor and greatly reducing labor and material costs. It can help promote the large-scale application of green leek maggot control technology and has positive significance for improving the problem of high pesticide residues in leeks.

[0048] The harvesting device includes a gathering component 1, a blade assembly 2, and a conveying component 3; the chives are gathered by the gathering component 1 and then cut by the blade assembly 2, and the cut chives are conveyed to the rear end of the machine body 7 and discharged through the conveying component 3;

[0049] The ash spreading device 5 includes an ash storage bin 51, an ash spreading bin 52, a sweeping impeller 522 rotatably disposed in the ash spreading bin 52, and a conveying pipe 53 disposed between the ash storage bin 51 and the ash spreading bin 52 and connecting the ash storage bin 51 and the ash spreading bin 52; the ash spreading bin 52 is provided with an ash outlet 521; the wood ash in the ash storage bin 51 enters the ash spreading bin 52 through the conveying pipe 53, and is discharged to the ground through the ash outlet 521 under the rotation of the sweeping impeller 522;

[0050] The film covering device 6 includes a first soil-digging shovel 62, a second soil-digging shovel 63, a roll 65 for installing the film, and a pressure roller 64; the initial end of the film is located at the lower end of the pressure roller 64; as the machine body 7 moves, the first soil-digging shovel 62 digs open the soil on the ground to form trenches, the pressure roller 64 covers the film on the ground, and the edge of the film is located in the trenches; the second soil-digging shovel 63 digs the soil on the ground back into the trenches and presses it at the edge of the film;

[0051] The walking device includes wheel 8 components for driving the body 7 to move.

[0052] like Figure 3 As shown, a more specific example of the blade assembly 2 in the harvesting device is as follows:

[0053] The blade assembly 2 includes a blade holder 22 and a blade 21 disposed on the blade holder 22 and rotating relative to the blade holder 22; the blade holder 22 is disposed on the machine body 7 via an L-shaped mounting member 23; wherein, the blade 21 is a disc-shaped blade 21;

[0054] The side wall of the L-shaped mounting component 23 is provided with a height adjustment groove 231, and a first bolt assembly slides through the height adjustment groove 231; the L-shaped mounting component 23 is fastened to the body 7 by the first bolt assembly;

[0055] The bottom wall of the L-shaped mounting component 23 is provided with an angle adjustment groove 232; a second bolt assembly is slidably inserted in the angle adjustment groove 232; the L-shaped mounting component 23 is fastened to the tool holder 22 by the second bolt assembly.

[0056] The height adjustment slide 231 and the first bolt assembly each include two sets, which correspond one to one. When the first bolt assembly is loosened, the first bolt assembly slides along the height adjustment slide 231, which can adjust the height of the L-shaped mounting part 23 on the machine body 7, thereby adjusting the height of the tool holder 22 and the blade 21.

[0057] The angle adjustment slide 232 and the second bolt assembly each include two sets, which correspond one to one. When the second bolt assembly is loosened, the second bolt assembly slides along the angle adjustment slide 232, which can adjust the angle of the blade holder 22 set on the L-shaped mounting part 23, thereby adjusting the angle or left and right position of the blade 21.

[0058] Each first bolt assembly and each second bolt assembly includes a bolt and a nut.

[0059] In addition, the blade assembly 2 also includes a blade 21 motor for driving the blade 21 to rotate, thereby enabling the blade 21 to cut the chives.

[0060] like Figure 1 and Figure 2 As shown, a more specific example of the conveying component 3 is as follows: the conveying component 3 includes two sets of conveyor belt assemblies; each set of conveyor belt assemblies includes a drive wheel 31 horizontally arranged at the rear end of the machine body 7, a driven wheel 32 vertically arranged at the front end of the machine body 7, and a conveyor belt arranged between the drive wheel 31 and the driven wheel 32; the two conveyor belts are arranged in parallel, and a clamping channel for conveying chives is formed between the two conveyor belts.

[0061] like Figure 3 As shown, the machine body 7 is also provided with two tensioning wheels 34, which are respectively arranged close to the driven wheel 32 to adjust the tension of the corresponding conveyor belt to ensure that the conveyor belt does not slip.

[0062] like Figure 4 As shown, in order to enable the transmission belt to automatically transport the cut chives to the rear end of the machine body 7, the harvesting device in this embodiment further includes a drive assembly 4 for driving the transmission assembly 3; the drive assembly 4 includes a drive motor 41, a first sprocket 42, a second sprocket 43, a third sprocket 44, and a chain 46; the first sprocket 42 is sleeved on the output shaft 411 of the drive motor 41, and the second sprocket 43 and the third sprocket 44 are respectively connected to the two drive wheels 31 one-to-one;

[0063] The chain 46 is wrapped around the outside of the first sprocket 42 and the second sprocket 43 in sequence; the third sprocket 44 engages with the outside of the chain 46.

[0064] It should be noted that the drive assembly 4 also includes an auxiliary sprocket 45 disposed above the third sprocket 44, and the chain 46 surrounds the outside of the third sprocket 44 so that the third sprocket 44 can engage with the outside of the chain 46.

[0065] like Figure 1 and Figure 2 As shown, a more specific example of the gathering component 1 is: the gathering component 1 includes two guide plates 11, and a gathering opening is formed between the two guide plates 11. The gathering opening gradually narrows from front to back, and the rear end of the gathering opening is located close to the driven wheel 32.

[0066] Furthermore, each of the guide plates 11 is inclined upwards from front to back relative to the ground, and the height of the front end of the convergence is lower than the height of the rear end of the convergence opening. The body 7 is provided with two forward-facing guide support plates 111, which correspond one-to-one with the two guide plates 11 and are used to support the guide plates 11.

[0067] In the harvesting device, the two guide plates 11 gather the chives to the rear end of the gathering opening, where they are cut by a high-speed rotating blade 21. After cutting, the chives enter the clamping channel and are then conveyed by the transmission belt to the rear end of the machine body 7 and discharged from the machine body 7, thus completing the automatic cutting of the chives.

[0068] like Figure 5 and Figure 6 As shown, a more specific example of the ash spreading device 5 is as follows: the ash spreading bin 52 is mounted on the machine body 7 via a support frame 54, and the ash outlet 521 faces the ground; an impeller motor 523 is provided at the bottom of the support frame 54; the output shaft 411 of the impeller motor 523 passes through the support frame 54 and the ash spreading bin 52 in sequence and is connected to the ash sweeping impeller 522.

[0069] The dust-sweeping impeller 522 includes a circular tray, on which a plurality of paddles are arranged around the center of the circular tray; the output shaft 411 of the impeller motor 523 passes through the center of the circular tray.

[0070] The ash storage bin 51 is located on the upper part of the machine body 7, and the top of the ash storage bin 51 has an opening for pouring wood ash into the ash storage bin 51. The ash spreading bin 52 is located on the lower part of the machine body 7; the ash spreading bin 52 is fully enclosed, with only one ash outlet 521 on the bottom surface of the ash spreading bin 52.

[0071] In the ash spreading device 5, the ash sweeping impeller 522 in the ash spreading bin 52 rotates under the drive of the impeller motor 523. The wood ash in the ash storage bin 51 enters the ash spreading bin 52 through the conveying pipe 53. Under the oscillation of the ash sweeping impeller 522, the wood ash flies out from the ash outlet 521 and is sprayed onto the freshly cut leek stubble.

[0072] like Figure 2As shown, a more specific example of the walking device is as follows: the wheel assembly includes four wheels 8 rotatably mounted on the bottom of the body 7, and the four wheels 8 are respectively located on the left and right sides of the front and rear ends of the body 7; wherein, wheel brackets 81 are provided between the two wheels 8 located at the front end of the body 7 and between the two wheels 8 located at the rear end of the body 7; both wheel brackets 81 are located at the bottom of the body 7, and the four wheels 8 are mounted at the bottom of the body 7 through the corresponding wheel brackets 81.

[0073] Each wheel 8 is connected to a wheel 8 motor. By independently controlling the forward and reverse rotation of the four wheel 8 motors, the machine body 7 can move forward, backward, turn, and turn around on the spot. The turning radius is small and the control is simple.

[0074] To ensure that the leek stubble is not unevenly dusted due to the varying speed of the machine body 7, this embodiment links the impeller motor 523 with the four wheel motors 8, and the dust-sweeping impeller 522 rotates in sync with the four wheels 8.

[0075] When the wheel 8 moves forward at a high speed, the impeller motor 523 rotates at a high speed, resulting in a large output of wood ash. When the wheel 8 moves forward at a slow speed, the impeller motor 523 rotates at a slow speed, resulting in a small output of wood ash. When it is detected that the motors of the four wheels 8 rotate at inconsistent speeds or at the same speed but at zero speed, the impeller motor 523 stops rotating. At this time, the machine body 7 is turning or stopped, so the ash dispensing bin 52 does not dispense ash.

[0076] like Figure 7 As shown, a more specific example of the film covering device 6 is as follows: The film covering device 6 further includes two sets of film covering components respectively disposed on the left and right sides of the machine body 7; each set of film covering components includes a film covering bracket 61, a first soil-removing shovel 62, a pressure roller 64, and a second soil-removing shovel 63; the first soil-removing shovel 62, the pressure roller 64, and the second soil-removing shovel 63 are arranged sequentially from front to back on the film covering bracket 61, and the groove formed by the pressure roller 64 and the first soil-removing shovel 62 is on the same straight line;

[0077] The roll 65 is disposed between the two film-coating supports 61, and the roll 65 is located in front of the pressure roller 64 and behind the ash outlet 521.

[0078] The shape and structure of the film-coating support 61 are as follows: each film-coating support 61 consists of a horizontal bar, a first vertical bar, and a second vertical bar. Both the first and second vertical bars are located in the middle of the horizontal bar, with the first vertical bar positioned in front of the second vertical bar. For each film-coating support 61, the horizontal bar is connected to the machine body 7; the first soil-removing shovel 62 is located at the front end of the horizontal bar, and the second soil-removing shovel 63 is located at the rear end of the horizontal bar. The pressure roller 64 is located at the lower end of the second vertical bar. The drum 65 is located between the first vertical bars of two film-coating supports 61.

[0079] It should be noted that: the first soil-removing shovel 62 and the second soil-removing shovel 63 are both inclined relative to the film-covering support 61; the first soil-removing shovel 62 is inclined from front to back towards the outside of the film-covering support 61, and the second soil-removing shovel 63 is inclined from front to back towards the inside of the film-covering support 61.

[0080] In the mulching device 6, as the machine body 7 moves forward, the first soil-removing shovel 62 pushes aside the surface soil on both sides in the direction of travel, and the pressure roller 64 presses precisely into the trench formed by the first soil-removing shovel 62. Because the pressure roller 64 presses on the film, the film unfolds as the machine body 7 moves forward, with both sides of the film falling into the trench. The pressure roller 64 moves forward along the edges of the film, stretching it as it goes. As the machine body 7 moves forward, the second soil-removing shovel 63 pushes the soil removed by the first soil-removing shovel 62 in the opposite direction towards the inside of the machine body 7, pressing it against the edges of the unfolded film, thus completing the mulching process.

[0081] The following are the steps for harvesting chives, spreading ash (wood ash), and mulching using a chive harvester according to this embodiment:

[0082] Step 1: Position the machine body 7 at the initial position on the ridge head, and then adjust the initial end of the film on the roll 65 to the pressure roller 64; start the blade 21 motor, drive motor 41 and impeller motor 523, and the cutting device, ash spreading device 5 and film covering device 6 are ready, and the machine body 7 starts working on a ridge-by-ridge basis;

[0083] Step 2: As the machine body 7 moves forward, the chives are guided by the guide plate 11 and enter the conveyor belt 33 in sequence. At the same time, they are cut by the blade 21. The cut chives are then transported along the conveyor belt 33 to the rear end of the machine body 7 and discharged from the machine body 7.

[0084] Step 3: The wood ash in the ash storage bin 51 enters the ash spreading bin 52 through the conveying pipe 53. The impeller motor 523 drives the sweeping impeller 522 to rotate. The wood ash flies out from the ash outlet 521 at the bottom of the ash spreading bin 52 and is sprayed onto the freshly cut leek stubble.

[0085] Step 4: The first shovel 62 pushes the surface soil on the ground to both sides in the direction of forward movement. As the pressure roller 64 presses on the film, the film also unfolds as the machine body 7 moves forward. The two sides of the film fall into the groove formed by the first shovel 62. The pressure roller 64 moves forward along the edge of the film while stretching the film.

[0086] Step 5: The second shovel 63 then pushes the soil that the first shovel 62 has pushed away in the opposite direction toward the inside of the machine body 7, and presses it onto the two sides of the unfolded film to hold the film in place, thus completing the film covering.

[0087] After harvesting the chives in this row, repeat steps one through five to harvest the chives in the next row until the harvesting, ash spreading, and mulching of chives in the entire field are completed.

[0088] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
