Description

Technical Field

[0001] The present invention relates to the technical field of harvesters, and particularly to an automatic harvester for leeks. Background Art

[0002] Since the best time for the harvesting period of leeks generally does not exceed 2 - 3 days, otherwise the leeks will become old and have extremely poor taste, it is necessary to use a harvester to harvest leeks.

[0003] In the existing harvesting machinery and equipment, due to the scattered growth of leeks, generally only the horizontal harvesting method can be adopted during harvesting, and it is difficult to adopt the rotary cutting method for harvesting. Moreover, the harvested leeks are often very scattered, resulting in relatively cumbersome subsequent collection of leeks. At the same time, manual sorting is also required. And during the cutting process, some weeds or fallen leaves may accidentally enter the leeks, and it is necessary to manually pick them out later, which is rather inconvenient. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an automatic harvester for leeks to solve the problems raised in the above background art. The structure of the present invention is novel. Multiple sets of collection components rotate cyclically inside the vertical frame through a sprocket chain device. When different collection components correspond to the position of the delivery port, through the rotation of the shaft rod, the collection box is pushed towards the position of the delivery port to facilitate receiving leeks. At the same time, on the other side, the leeks are sent out from the collection box. During this process, the leeks have been screened by shaking, thereby reducing the difficulty of manually selecting impurities separately later, tidying up the leeks, and facilitating subsequent bundling.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: An automatic harvester for leeks includes a machine head. Two guide plates are symmetrically fixed at the front end of the machine head, and a lifting machine box is installed at the tail end of the machine head. A delivery port is opened at the upper end of the lifting machine box. A vertical frame is fixed at the rear end of the machine head. Moving wheels are installed on both sides of the bottom of the machine head and the vertical frame. Sprocket chain devices are installed on the inner walls of both sides of the vertical frame, and collection components are installed on the surface of the chain of the sprocket chain device. The collection component includes a collection box. A plurality of groups of collection boxes are equidistantly installed on the chain. Sieve slots are opened on the bottom surface of the collection box, and a collection box is fixed at the bottom of the collection box. A shaft rod is rotatably installed inside the middle of the vertical frame, and a turntable is fixed on the surface of the shaft rod. Electric push rods are fixed on both sides of the turntable, and a pressing ball is fixed at the extending end of the electric push rod. A centralized box is fixed at the rear end of the vertical frame. The collection boxes parallel to both sides of the shaft rod respectively correspond to the bottom of the delivery port and the top of the centralized box.

[0006] Further, the collection component further includes counterweights. The counterweights are fixedly installed at equal intervals on the bottom of the collection box, and a weighing sensor is fixed on the inner wall of the bottom of the collection frame. The collection box is fixedly connected to the collection frame by bolts.

[0007] Further, a cross plate is fixed on the surface of the chain of the sprocket and chain device corresponding to the position of each collection frame. A connection frame is slidably sleeved on the surface of the cross plate, and the connection frame is rotatably connected to the outer wall of the collection frame. A first spring is fixed between the outer end of the connection frame and the cross plate.

[0008] Further, telescopic columns are rotatably installed inside both sides of the collection frame through bearings, and the extending ends of the telescopic columns are fixedly connected to the connection frame. A second spring is fixed between the extending end and the receiving end of the telescopic column.

[0009] Further, a top plate is fixed on the top of the shaft rod, and a moving groove is formed on the surface of the top plate. A pushing frame is slidably installed inside the moving groove. A connecting plate is fixed between the two pushing frames, and the connecting plate slides along the inside of the moving groove. The two ends of the pushing frame are in sliding contact with the two sides of the bottom of the upper two groups of collection frames.

[0010] Further, gears are fixed at both ends of the shaft rod, and a toothed plate is meshed with one side of the gear. A sliding frame is fixed at the position corresponding to the toothed plate on the bottom of the top plate, and the toothed plate slides along the sliding frame.

[0011] Further, a pulling rope is fixed on the top of the toothed plate, and the other end of the pulling rope passes into the moving groove and is fixedly connected to the pushing frame. The toothed plates on both sides of the shaft rod are located on the opposite sides of the gear.

[0012] Further, a first moving plate is provided on one side of the collection frame, and a second moving plate is provided on the other side of the collection frame. Connecting rods are fixed on both sides of the tops of the first moving plate and the second moving plate.

[0013] Further, sliding grooves are formed on the inner walls of both sides of the collection frame, and the tops of both sides of the first moving plate slide along the inside of the sliding grooves.

[0014] Further, a first motor is fixed on the outer top of the vertical frame, and the output end of the first motor is fixedly connected to the driving wheel of the sprocket and chain device. A second motor is fixed at the bottom of the vertical frame where the first motor is located, and the output end of the second motor is fixedly connected to the shaft rod.

[0015] Advantages of the present invention:

[0016] 1. The counterweight at the bottom of the collection box in the present invention can keep the collection frame with the opening facing upwards all the time when it moves along with the sprocket chain device, thereby avoiding the dropping of leeks and the reception of leeks. During this process, the connection frame slides along the cross plate, and the connection frame and the telescopic column rotate along both sides of the collection frame to maintain the connection with the collection frame. At the same time, the first spring and the second spring have a certain elastic reset ability for the position where the connection frame is located.

[0017] 2. The weighing sensor built into the collection frame in the present invention can weigh the amount of leeks received. After reaching a certain amount, the first motor continues to drive the sprocket chain device to rotate to collect the next set of collection frames. And the collection frames moved to the upper layer can sway left and right through the connection relationship between the telescopic columns on both sides and the connection frame, so as to collect fine impurities into the collection box through the sieve trough. By manually disassembling and removing the collection box, the impurities can be cleaned.

[0018] 3. When there are two sets of collection frames corresponding to the sending and receiving positions in the present invention, there are two sets at the top that are clamped inside the push frame. Since the push frame only slides in contact with both sides of the collection frame, it will not interfere with the movement of the collection frame along with the sprocket chain device. When the shaft rod rotates, the gear rotates and meshes with the toothed plate on the side plate. Because the positions of the toothed plates meshed by the two gears are opposite, one rises and the other falls. The pull ropes of the two toothed plates drive the push frame to slide along the moving groove, thereby pushing the collection frame to generate a lateral movement. As the shaft rod moves in the reverse direction, a reverse lateral movement will occur. During this process, because the leeks are scattered inside the collection frame, the fine impurities inside can be screened out through the sieve trough under the action of shaking.

[0019] 4. For the collection frame at the receiving position in the present invention, since the extrusion ball contacts the second moving plate at this time and the first moving plate cannot move outwards continuously, under the pushing action of the extrusion ball, the entire collection frame moves to the bottom of the sending frame to receive the leeks.

[0020] 5. The present invention drives the electric push rod to rotate to the inner sides of the two collection frames by the shaft rod. Since the opening of the collection frame always faces upwards, the positions of the first moving plate and the second moving plate on both sides of the collection frame are just opposite. And because the first moving plate is initially at one end of the sliding groove, at the sending position, under the pushing action of the extended extrusion ball of the electric push rod, the first moving plate and the second moving plate are preferentially moved outwards to send out the leeks inside the collection frame.

[0021] 6. Compared with the prior art, multiple sets of collection components rotate cyclically inside the vertical frame through a sprocket and chain device. When different collection components correspond to the positions of the delivery outlets, through the rotation of the shaft rod, the collection box is pushed towards the position of the delivery outlet to facilitate receiving leeks. At the same time, on the other side, the leeks are sent out from the collection box. During this process, the leeks have been screened by shaking, thereby reducing the difficulty of manually selecting impurities separately later, tidying up the leeks, and facilitating subsequent bundling.

Detailed implementation manners

[0031] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Please refer to Figures 1 to 8, the present invention provides a technical solution: a leek automatic harvester, including a machine head 1. Two guiding plates 11 are symmetrically fixed at the front end of the machine head 1, and a lifting machine box 12 is installed at the tail end of the machine head 1. A delivery port 13 is opened at the upper end of the lifting machine box 12. A vertical frame 2 is fixed at the rear end of the machine head 1. Moving wheels 14 are installed on both sides of the bottom of the machine head 1 and the vertical frame 2. A sprocket chain device 23 is installed on the inner walls on both sides of the vertical frame 2, and a collection assembly 3 is installed on the surface of the chain of the sprocket chain device 23. The collection assembly 3 includes a collection box 31. A plurality of groups of the collection boxes 31 are installed on the chain at equal intervals. A sieve groove 32 is opened on the bottom surface of the collection box 31, and a collection box 34 is fixed at the bottom of the collection box 31. A shaft rod 35 is rotatably installed inside the middle of the vertical frame 2, and a turntable 36 is fixed on the surface of the shaft rod 35. Electric push rods 37 are fixed on both sides of the turntable 36, and an extrusion ball 38 is fixed at the extended end of the electric push rod 37. A centralized box 4 is fixed at the rear end of the vertical frame 2. The collection boxes 31 parallel to both sides of the shaft rod 35 respectively correspond to the bottom of the delivery port 13 and the top of the centralized box 4. The structure and principle of the front machine head 1 of this device are prior art. Inside the machine head 1, the leeks are gathered in the middle position through the guiding plates 11. After the leeks are cut by a rotating cutter, they are lifted to the position of the delivery port 13 by the lifting machine box 12 and sent out. When using the device, the device is pushed to move. The machine head 1 gathers and cuts the leeks on the path. The leeks are sent out from the delivery port 13 by the lifting machine box 12 and fall into the collection box 31. The sprocket chain device 23 drives a plurality of groups of collection boxes 31 to rotate in a cycle, alternately receiving the leeks from the delivery port 13. At the receiving position and the sending position, due to the rotation of the shaft rod 35, the collection box 31 is moved close to the bottom of the delivery port 13 to prevent the leeks from falling. On the other side, the leeks are pushed out and fall into the centralized box 4 for subsequent bundling work. The collection box 31 moved to the top shakes horizontally when the shaft rod 35 rotates, screening out the impurities inside the leeks.

[0033] In this embodiment, the collection assembly 3 further includes counterweights 33. The counterweights 33 are fixedly installed at equal intervals on the bottom of the collection box 34. A weighing sensor is fixed on the inner wall of the bottom of the collection frame 31. The collection box 34 is fixedly connected to the collection frame 31 by bolts. A cross plate 24 is fixed at a position corresponding to each collection frame 31 on the surface of the chain of the sprocket and chain device 23. A connection frame 313 is slidably sleeved on the surface of the cross plate 24, and the connection frame 313 is rotatably connected to the outer wall of the collection frame 31. A first spring 314 is fixed between the outer end of the connection frame 313 and the cross plate 24. Telescopic columns 315 are rotatably installed on both sides of the collection frame 31 through bearings, and the extended end of the telescopic column 315 is fixedly connected to the connection frame 313. A second spring 316 is fixed between the extended end and the retracted end of the telescopic column 315. A first motor 21 is fixed to the top of the outer side of the vertical frame 2, and the output end of the first motor 21 is fixedly connected to the driving wheel of the sprocket and chain device 23. A second motor 22 is fixed to the bottom of the vertical frame 2 where the first motor 21 is located, and the output end of the second motor 22 is fixedly connected to the shaft rod 35. The weighing sensor built in the collection frame 31 can weigh the amount of leeks received. After reaching a certain amount, the first motor 21 continues to drive the sprocket and chain device 23 to rotate for the collection of the next set of collection frames 31. The collection frame 31 that moves to the upper layer can swing left and right through the connection relationship between the telescopic columns 315 on both sides and the connection frame 313, so as to collect fine impurities into the collection box 34 through the sieve slot 32. By manually removing the collection box 34, the impurities can be cleaned. The counterweights 33 at the bottom of the collection box 34 can keep the collection frame 31 facing upward with the opening all the time when moving along with the sprocket and chain device 23, thereby avoiding the dropping of leeks and the reception of leeks. During this process, the connection frame 313 slides along the cross plate 24, and the connection frame 313 and the telescopic column 315 rotate along both sides of the collection frame 31 to maintain the connection with the collection frame 31. At the same time, the first spring 314 and the second spring 316 have a certain elastic reset ability for the position where the connection frame 313 is located.

[0034] In this embodiment, a top plate 39 is fixed to the top of the shaft rod 35, and a moving groove 324 is formed on the surface of the top plate 39. A push frame 310 is slidably installed inside the moving groove 324. A connecting plate 312 is fixed between the two push frames 310, and the connecting plate 312 slides along the inside of the moving groove 324. The two ends of the push frame 310 are in sliding contact with the two sides of the bottom of the upper two groups of collection frames 31. Gears 311 are fixed to both ends of the shaft rod 35, and a toothed plate 321 is meshed with one side of the gear 311. A sliding frame 322 is fixed to the bottom of the top plate 39 corresponding to the position of the toothed plate 321, and the toothed plate 321 slides along the sliding frame 322. A pull rope 323 is fixed to the top of the toothed plate 321, and the other end of the pull rope 323 passes into the moving groove 324 and is fixedly connected to the push frame 310. The toothed plates 321 on both sides of the shaft rod 35 are located on the opposite sides of the gear 311. When there are two groups of collection frames 31 corresponding to the sending and receiving positions, two groups are clamped inside the push frame 310 at the top. Because the push frame 310 only slides in contact with the two sides of the collection frame 31, it does not interfere with the movement of the collection frame 31 along with the sprocket chain device 23. When the shaft rod 35 rotates, the gear 311 rotates and meshes with the toothed plate 321 of the side plate. Because the positions of the toothed plates 321 meshed with the two gears 311 are opposite, one rises and the other falls. The push frame 310 is driven to slide along the moving groove 324 by the pull ropes 323 of the two toothed plates 321, thereby pushing the collection frame 31 to move horizontally. As the shaft rod 35 moves in the reverse direction, a reverse horizontal movement will occur. During this process, because the leeks are in a scattered state inside the collection frame 31, the fine impurities inside can be screened out through the sieve slot 32 under the action of shaking.

[0035] In this embodiment, a first moving plate 318 is provided on one side of the collection frame 31, and a second moving plate 320 is provided on the other side of the collection frame 31. Connecting rods 319 are fixed to both sides of the tops of the first moving plate 318 and the second moving plate 320. Sliding grooves 317 are formed on the inner walls of both sides of the collection frame 31, and the two sides of the top of the first moving plate 318 slide along the inside of the sliding grooves 317. When the collection frame 31 moves to the receiving position and the sending position, the electric push rod 37 is driven by the shaft rod 35 to rotate to the inside of the two collection frames 31. Because the opening of the collection frame 31 always faces upward, the positions of the first moving plate 318 and the second moving plate 320 on both sides of the two collection frames 31 are just opposite. Also, because the first moving plate 318 is initially at one end of the sliding groove 317, at the sending position, under the pushing action of the extended electric push rod 37 pressing the ball 38, the first moving plate 318 and the second moving plate 320 are first moved outward to send out the leeks inside the collection frame 31. For the collection frame 31 at the receiving position, because the ball 38 contacts the second moving plate 320 at this time and the first moving plate 318 cannot continue to move outward, the entire collection frame 31 is moved to the bottom of the sending frame under the pushing action of the ball 38 to receive the leeks.

[0036] When using the device, push the device to move. The machine head 1 gathers and cuts the leeks on the path, and the lifting machine box 12 sends the leeks out from the delivery outlet 13 and drops them inside the collection box 31. The sprocket chain device 23 drives multiple groups of collection boxes 31 to rotate cyclically, alternately receiving the leeks at the delivery outlet 13. At the receiving position and the delivery position, with the rotation of the shaft rod 35, the collection box 31 is moved close to the bottom of the delivery outlet 13 to prevent the leeks from falling. On the other side, the leeks are pushed out and dropped into the centralized box 4 for subsequent bundling work. The shaft rod 35 drives the electric push rod 37 to rotate to the inner sides of the two collection boxes 31. Since the opening of the collection box 31 always faces upward, the positions of the first moving plate 318 and the second moving plate 320 on the two sides of the collection box 31 are just opposite. Also, because the first moving plate 318 is initially at one end of the sliding groove 317, at the delivery position, under the pushing action of the electric push rod 37 extending and squeezing the ball 38, the first moving plate 318 and the second moving plate 320 are first moved outward to send out the leeks inside the collection box 31. For the collection box 31 at the receiving position, since the ball 38 contacts the second moving plate 320 at this time and the first moving plate 318 cannot move outward continuously, under the pushing action of the ball 38, the entire collection box 31 moves to the bottom of the delivery box to receive the leeks. The collection box 31 at the top shakes horizontally when the shaft rod 35 rotates. When there are two groups of collection boxes 31 corresponding to the delivery and receiving positions, there are two groups at the top that are clamped inside the push frame 310. Since the push frame 310 only slides in contact with the two sides of the collection box 31, it will not interfere with the movement of the collection box 31 along with the sprocket chain device 23. When the shaft rod 35 rotates, the gear 311 rotates and meshes with the toothed plate 321 on the side plate. Since the positions of the toothed plates 321 meshed by the two gears 311 are opposite, one goes up and the other goes down. The pull rope 323 of the two toothed plates 321 drives the push frame 310 to slide along the moving groove 324, thereby pushing the collection box 31 to generate a horizontal movement. With the reverse movement of the shaft rod 35, a reverse horizontal movement will occur. During this process, because the leeks are scattered inside the collection box 31, the fine impurities inside can be screened out through the sieve slot 32 under the shaking action, removing the impurities inside the leeks. The built-in weighing sensor in the collection box 31 can weigh the amount of received leeks. After reaching a certain amount, the first motor 21 continues to drive the sprocket chain device 23 to rotate to collect the next group of collection boxes 31. And the collection box 31 moved to the upper layer can shake left and right through the connection relationship between the two side telescopic columns 315 and the connection frame 313, so as to collect the fine impurities into the collection box 34 through the sieve slot 32. By manually disassembling and removing the collection box 34, the impurities can be cleaned. The counterweight 33 at the bottom of the collection box 34 can keep the collection box 31 always facing upward when moving along with the sprocket chain device 23, thereby avoiding the leeks from falling and receiving the leeks. During this process, through the connection frame 313 sliding along the cross plate 24,The connecting frame 313 and the telescopic column 315 rotate along both sides of the collection box 31 to maintain the connection with the collection box 31, and at the same time, the first spring 314 and the second spring 316 have a certain elastic reset ability for the position where the connecting frame 313 is located.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
