Its working method is as follows: the motor drives the turntable to rotate counterclockwise intermittently at a certain rhythm, rotating once and pausing once; the staff put the scallions root-down into each vertical cavity at the front of the rotating cylinder in turn. Driven by the turntable, the rotating cylinder rotates counterclockwise. The scallion root cutting mechanism cuts the roots of the scallions in each vertical cavity on its right side. For the scallions with the roots cut, the staff put several scallions with the roots and outer leaves removed into the scallion bundling mechanism, which bundles the scallions.

[0004] The problem with the aforementioned existing technology is:

[0005] First: It can only be used for processing scallions, and the scallions need to be placed manually in the working position. It cannot complete the fully automatic cutting and bundling.

[0006] Second: It cannot adjust the cutting position of scallions according to the length of the roots. It can only cut the roots at a single height and cannot conveniently adjust the cutting position for different root lengths. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a device for bundling and cutting roots of stem crops. Compared with the above-mentioned prior art, this device can be widely used for cutting and bundling root products, and can complete fully automatic cutting and bundling. The cutting position can be adjusted according to the required root length to better meet the cutting needs.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical means:

[0009] A baling and root-cutting device for stalk crops includes a tracked conveyor mechanism, a root-cutting and collecting mechanism, and a rotary crop collecting mechanism located below the discharge end of the tracked conveyor mechanism. The rotary crop collecting mechanisms are evenly spaced along the circumference on sub-rotating mechanisms. Each sub-rotating mechanism is driven to rotate, causing its rotary crop collecting mechanisms to sequentially receive material conveyed by the tracked conveyor mechanism. The material received by the rotary crop collecting mechanisms is then transported to the sub-rotating mechanisms. The material transport to the sub-rotating mechanisms is located above a main rotating mechanism, and the main rotating mechanism is located below the sub-rotating mechanisms that transport the material. Each sub-rotating mechanism... A material collection hole is located at the center; the main rotating mechanism has spaced discharge holes, which correspond to the material collection hole and are connected to it; when the material in the rotating crop collection mechanism is conveyed into the material collection hole, it falls downward into the discharge hole, and an opening and closing plate is provided at the bottom opening of the discharge hole, which is driven to open or close the discharge hole; a root cutting and collecting mechanism is provided below the main rotating mechanism; the root cutting and collecting mechanism is equipped with a root cutting blade and a tying machine; a tray and a tying machine are provided below the root cutting blade, the tray is driven to lift and receive the cut crop, and the tying machine ties the cut crop.

[0010] The advantages of this utility model are:

[0011] First: The material is conveyed to the rotary crop collection mechanism via a tracked conveyor, and then conveyed to the root cutting and collection mechanism via the sub-rotating mechanism and the main rotating mechanism; thus realizing the automatic conveying of materials until the binding is completed, reducing labor costs.

[0012] Second: A tray and a tying machine are located below the root-cutting blade. The tray is driven to rise and fall to receive the crop to be cut, and the tying machine ties the cut crop together. The tray can be driven up or down as needed to adjust the cutting position to correspond with the root-cutting blade. Therefore, this technical solution allows for adjustment of the cutting position according to the required root length, better meeting cutting needs.

[0013] Further preferred technical solutions are as follows:

[0014] The tracked conveyor mechanism includes a right conveyor track and a left conveyor track, which are mounted on a track frame. The conveying clamping interval between the right and left conveyor tracks can be adjusted by the track frame.

[0015] The rotary crop collecting mechanism includes a posture adjustment shell, an air pump, an outer one-way door, and an inner one-way door. The posture adjustment shell is vertically arranged with an opening at the top and a bottom connection to the rotary mechanism. The inner and outer sides of the posture adjustment shell are respectively equipped with an inner one-way door and an outer one-way door, both hinged to the outside of the posture adjustment shell, with a return spring at the hinge shaft. An air bladder is located inside the posture adjustment shell, connected to the air pump. Inflating the air bladder pushes the crop out of the posture adjustment shell through the inner one-way door. The right and left conveyor belts of the tracked conveyor mechanism clamp the crop and push it through the outer one-way door into the posture adjustment shell. Crops are fed in at intervals. After the crop enters the posture adjustment shell, the outer one-way door resets under the action of the return spring. The top of the posture adjustment shell is open for easy observation of the internal components.

[0016] The rotating mechanism includes a rotating disk, a rotating disk tray, a rack, a small gear ring, a small stepper motor, a pinion, a small worm gear, a small worm, a medium stepper motor, ball bearings, and a protective base. The rotating disk is connected to the rotating disk tray. The small stepper motor drives the pinion below it to rotate, and the pinion meshes with both the small gear ring and the rack. The pinion and rack are evenly spaced along the small gear ring, and the small gear ring drives its pinion to rotate, thereby driving the other racks to move. The medium stepper motor is fixed inside the protective base, and its output shaft is connected to a small worm gear. The small worm gear meshes precisely with the small worm gear to achieve power transmission. The upper part of the small worm gear... The end is connected to the sub-rotating tray, and the upper part of the protective base is connected to the sub-rotating tray; the protective base is installed on the main rotating disk, and the inside of the protective base has small grooves with intervals. Each groove is filled with a ball bearing. The ball bearing supports the sub-rotating tray. When the sub-rotating tray rotates, the ball bearing reduces the friction between the protective base and the sub-rotating tray; the protective base is equipped with an electric slip ring with a locking buckle. Each segment of the wire of the small stepper motor and the medium stepper motor is connected to an anti-tangling electric slip ring. The electric slip rings are uniformly fixed to the electric slip ring locking buckle and finally led out to the lower part through the wiring hole to prevent the wires from tangling during the rotation of the mechanism.

[0017] The main rotating mechanism includes a large motor base, a large stepper motor, a large gear, a large gear ring, a hinged disc, a cylindrical pin, and a main rotating disc. The large stepper motor is mounted on the base, and the large gear is driven by the motor, meshing with the large gear ring. The large gear ring is fixedly installed inside the main rotating disc, and the gear ring drives the main rotating disc to rotate. The bottom surface of the main rotating disc has spaced discharge holes. An electric slip ring master clip is mounted on the top of the main rotating disc. Each section of wire from the air pump, small stepper motor, medium stepper motor, large stepper motor, and hinged motor is equipped with an electric slip ring. All wires are introduced from the top, and the electric slip rings are then engaged in the master clip to prevent wire tangling during rotation.

[0018] The root cutting and collection mechanism includes a root cutting blade, a blade holder, a tying machine, a tying machine base, a discharge tying ring, a tray, a cylinder box, a collection track, and a cylinder. The root cutting blade is mounted on the blade holder, which is mounted on the tying machine base. The blade holder contains a motor that drives the root cutting blade. The tying machine is mounted on the tying machine base. The tray is positioned directly below the tying opening of the tying machine. The tray is connected to the cylinder drive end through the cylinder box. The tray is lifted and lowered by the cylinder. The tray supports the crop to be cut and adjusts the cutting position. The collection track is connected to the cylinder box.

[0019] The right and left conveyor tracks are mounted together on an adjustable-size support. During operation, the right conveyor track rotates counter-clockwise, while the left conveyor track rotates clockwise, gripping and transporting stalk-type crops. Adjusting the support dimensions allows for flexible gripping and transport, significantly reducing damage to stalk-type crops, and together they complete the transport of these crops.

[0020] The air pump is mounted on the main rotating disc, and the air pump and the air bag are connected by a flexible air tube and a rotating sealing ring to meet the rotation requirements.

[0021] The rotary crop collecting mechanism features a circular array on the sub-rotating disks, spaced 72° apart. Each pair of pinions and racks is also 72° apart; the racks move inward, driving the attitude adjustment housing to complete the local rotation. At the bottom, a stepper motor drives a small worm gear to rotate clockwise, which in turn drives a small turbine to rotate clockwise, thus rotating the sub-rotating disk tray and the sub-rotating disk itself clockwise to complete the sub-rotation mechanism. During rotation, ball bearings are installed in the grooves inside the protective base, significantly reducing rotational wear.

[0022] When the mechanism is working, the large stepper motor is turned on, which drives the large gear to rotate clockwise. The large gear then drives the large gear ring to rotate clockwise through its teeth. Finally, the large gear ring drives the main rotating disk to rotate clockwise. Whenever it rotates to the position of the root cutting blade, it stops rotating. The opening and closing disk rotates clockwise around the cylindrical pin to open, controlling the crop to slide down and completing the rotation of the main rotating mechanism.

[0023] The mechanism works as follows:

[0024] The crops pass through the laser sensor, indicating the first batch of crops has entered. After passing through the outer one-way gate, they enter the attitude adjustment shell. The sub-rotating disk rotates 72° clockwise. This process is repeated five times until each attitude adjustment shell is filled with crops. At this point, the main rotating disk rotates 72° clockwise, causing the attitude adjustment shell on the other side to rotate to the working position and begin receiving crops. The attitude adjustment shells that have completed receiving work rotate to the position opposite to the direction of movement of the attitude adjustment shells that have started working. Then, the rack moves inward, driving the attitude adjustment shells to complete the partial rotation work, controlling each attitude adjustment shell to move closer to the material collection hole until a cylindrical cavity is formed in the middle. The airbag is connected and set inside the inner one-way gate. The air pump controls the inflation of the internal airbag. As the airbag volume increases, the crops in the attitude adjustment shells are squeezed out from the inner one-way gate. The five airbags work simultaneously, causing the crops in the five attitude adjustment shells to be squeezed out at the same time and fall into the material collection hole of the sub-rotating disk, forming five vertically close-to-each-crops, completing the attitude adjustment and collection work.

[0025] The cylinder controls the tray to rise and catch the bottom of the falling crop, while the top of the crop remains inside the discharge hole, preventing the crop from scattering. The crop moves up or down with the tray, and the height is adjusted to find the appropriate cutting position. The motor in the blade holder is controlled to drive the cutting blade to rotate and complete the cutting. Then, the cylinder controls the tray to fall. During the descent of the tray, the baler quickly completes the baling at the appropriate position. When the tray reaches the bottom, the baled crop slides down the collection track, reducing the loss caused by manual cutting. The fully automatic baler achieves rapid baling.

[0044] The present invention will be further described below with reference to the embodiments.

[0045] See Figures 1-12As can be seen, the stalk and stem crop baling and root cutting device of this utility model consists of a tracked conveyor mechanism 1, a rotary crop collection mechanism 2, a sub-rotation mechanism 3, a main rotation mechanism 4, and a root cutting and collection mechanism 5.

[0046] The tracked conveyor 1 has a rotary crop collection mechanism 2 located below the discharge end. The tracked conveyor 1 includes a right conveyor track 101 and a left conveyor track 102.

[0047] The tracked conveyor 1 transports materials to the rotary crop collection mechanism 2.

[0048] The rotary crop collecting mechanism 2 is evenly spaced along the circumference on the sub-rotating mechanism 3. The rotary crop collecting mechanism 2 includes a posture adjustment shell 201, an air pump 202, an outer one-way door 203, and an inner one-way door 204. The posture adjustment shell 201 is vertically arranged, with an opening at the top and a bottom end connected to the sub-rotating mechanism 3. The inner and outer sides of the posture adjustment shell 201 are respectively provided with an inner one-way door 204 and an outer one-way door 203. Both the inner one-way door 204 and the outer one-way door 203 are hinged to the outside of the posture adjustment shell 201. The connection is made with a return spring at the hinge shaft; an air bladder is provided inside the attitude adjustment housing 201, which is connected to the air pump 202. When the air bladder is inflated, the crop inside the attitude adjustment housing 201 is pushed out from the inner one-way door 204; the right conveyor track 101 and the left conveyor track 102 of the track conveyor mechanism 1 hold the crop and push it out from the outer one-way door 203 into the attitude adjustment housing 201. The crop is fed in once at intervals. After the crop enters the attitude adjustment housing 201, the outer one-way door 203 is reset by the action of the return spring.

[0049] The rotary crop collecting mechanism 2 collects the material and then conveys it to the main rotary mechanism 4.

[0050] The rotating mechanism 3 includes a rotating disk 301, a rotating disk tray 302, a rack 303, a small gear ring 304, a small stepper motor 305, a pinion 306, a small worm gear 307, a small worm 308, a medium stepper motor 309, a ball bearing 310, and a protective base 311. The rotating disk 301 is connected to the rotating disk tray 302. The small stepper motor 305 drives the pinion 306 below it to rotate. The pinion 306 meshes with the small gear ring 304 and the rack 303. The pinion 306 and the rack 303 are evenly spaced along the small gear ring 304. The small gear ring 304 drives its pinion 306 to rotate, thereby driving the other racks 303 to move. The medium stepper motor 309 is fixed inside the protective base 311, and its output shaft is connected to the small worm gear 308. The small worm gear 308 and the small stepper motor 309 are connected to the small worm gear 308. The small turbine 307 is precisely engaged to achieve power transmission. The upper end of the small turbine 307 is connected to the sub-rotating disk tray 302. The sub-rotating disk tray 302 is connected to the upper part of the protective base 311. The protective base 311 is installed on the main rotating disk 407. The protective base 311 has small grooves arranged at intervals inside. Each groove is equipped with a ball bearing 310. The ball bearing 310 supports the sub-rotating disk tray 302. When the sub-rotating disk tray 302 rotates, the ball bearing 310 reduces the friction between the protective base 311 and the sub-rotating disk tray 302. The protective base 311 has an electric slip ring with a buckle 312 inside. Each segment of the wire of the small stepper motor 305 and the medium stepper motor 309 is connected to an anti-tangling electric slip ring. The electric slip rings are uniformly fixed to the electric slip ring buckle 312 and finally led out to the lower part through the wiring hole 313 to prevent the wires from tangling during the rotation of the mechanism.

[0051] The main rotating mechanism 4 includes a large motor base 401, a large stepper motor 402, a large gear 403, a large gear ring 404, a hinged disc 405, a cylindrical pin 406, and a main rotating disc 407. The large stepper motor 402 is placed on the large motor base 401. The large gear 403 is driven by the large stepper motor 402 and meshes with the large gear ring 404. The large gear ring 404 is fixedly installed inside the main rotating disc 407. The large gear ring 404 drives the main rotating disc 407 to rotate. The bottom surface of the main rotating disc 407 is provided with spaced discharge holes 409. The arrangement of the discharge holes 409 is consistent with the rotation of the crop. The material collection hole 314 of the collecting mechanism 2 is set accordingly, and the material falls from the material collection hole 314 into the discharge hole 409; the discharge hole 409 is hinged with an opening and closing plate 405, which is driven to open or close the discharge hole 409; the electric slip ring main buckle 408 is installed on the top of the main rotating plate 407, and electric slip rings are installed on each section of the wires of the air pump 202, the small stepper motor 305, the medium stepper motor 309, the large stepper motor 402, and the opening and closing motor 406. After all their wires are introduced from the top, the electric slip rings are locked into the electric slip ring main buckle 408 to prevent the wires from getting tangled during the rotation of the mechanism.

[0052] The main rotating mechanism 4 collects the material and transports the collected material to the root cutting and collection mechanism 5.

[0053] The root cutting and collection mechanism 5 includes a root cutting blade 501, a blade holder 502, a tying machine 503, a tying machine base 504, a tray 505, a cylinder box 506, a collection track 507, and a cylinder 508. The root cutting blade 501 is mounted on the blade holder 502, which is mounted on the tying machine base 504. The blade holder 502 is equipped with a motor that drives the root cutting blade 501. The tying machine 503 is mounted on the tying machine base 504. The tray 505 is positioned directly below the tying opening of the tying machine 503. The tray 505 is connected to the driving end of the cylinder 508 through the cylinder box 506. The tray 505 is driven to rise and fall by the cylinder 508. The tray 505 supports the crop to be cut and adjusts the cutting position. The collection track 507 is connected to the cylinder box 506.

[0054] The right conveyor belt 101 and the left conveyor belt 102 are mounted together on an adjustable-size support. During operation, the right conveyor belt 101 rotates counter-clockwise, and the left conveyor belt 102 rotates clockwise, thus gripping and transporting stalk crops. Adjusting the size of the support allows for flexible gripping and transport, significantly reducing damage to stalk crops and jointly completing the transport of these crops.

[0055] The air pump 202 is mounted on the main rotating disk 407. The air pump 202 is connected to the air bag through a flexible air tube and a rotating sealing ring to meet the rotation requirements.

[0056] Figure 3 As shown, the rotary crop collecting mechanism 2 is arranged in a circular array on the sub-rotating disk 301, with each pair spaced 72° apart. Each pair of pinions 306 and racks 303 is spaced 72° apart, and the inward movement of the racks 303 drives the attitude adjustment housing 201 to complete a partial rotation. At the bottom, the stepper motor 309 drives the small worm gear 308 to rotate clockwise, which in turn drives the small turbine 307 to rotate clockwise, thereby causing the sub-rotating disk tray 302 and the sub-rotating disk 301 to rotate clockwise, completing the operation of the sub-rotating mechanism 3. During rotation, the groove inside the protective base 311 is equipped with ball bearings 310, greatly reducing rotational wear.

[0057] When the mechanism is working, the large stepper motor 402 is turned on, which drives the large gear 403 to rotate clockwise. The large gear 403 then drives the large gear ring 404 to rotate clockwise through its teeth. Finally, the large gear ring 404 drives the main rotating disk 407 to rotate clockwise. Whenever it rotates to the position of the root cutting blade 501, it stops rotating. The opening and closing disk 405 rotates clockwise around the cylindrical pin 406 to open, controlling the crop to slide down and completing the rotation of the main rotating mechanism 4.

[0058] The mechanism works as follows:

[0059] The first crop enters through the laser sensor 103, passes through the outer one-way door 203, and enters the attitude adjustment shell 201. The sub-rotating disk 301 rotates 72° clockwise. After repeating this process five times, each attitude adjustment shell 201 is filled with crops. At this point, the main rotating disk 407 rotates 72° clockwise, causing the attitude adjustment shell 201 on the other side to rotate to the working position and begin receiving crops. The attitude adjustment shell 201 that has completed receiving crops rotates to the position opposite to the direction of movement of the attitude adjustment shell 201 that has started working. After this, the rack 303 moves inward. The attitude adjustment shell 201 is driven to complete the partial rotation, and each attitude adjustment shell 201 is controlled to move closer to the material collection hole 314 until a cylindrical cavity is formed in the middle. The airbag is connected and set inside the inner one-way door 204. The air pump 202 controls the internal airbag to inflate. As the airbag volume increases, the crops in the attitude adjustment shell 201 are squeezed out from the inner one-way door 204. The five airbags work at the same time, so that the crops in the five attitude adjustment shells 201 are squeezed out at the same time and fall into the material collection hole 314 of the rotating disk 301, forming five parts of crops that are vertically close together, thus completing the attitude adjustment and collection work.

[0060] Cylinder 508 controls the tray 505 to rise and catch the crops. The crops move with the tray and the height is adjusted to find a suitable cutting position. The motor in the blade holder 502 is controlled to drive the cutting blade 501 to rotate and complete the cutting. Then, cylinder 508 controls the tray to fall. During the descent of the tray, the baler 503 quickly completes the baling at the appropriate position. When the tray 505 falls to the bottom, the baled crops slide down the collection track 507, reducing the loss caused by manual cutting. The fully automatic baler achieves rapid baling.

[0061] The working process of this utility model is as follows:

[0062] Before operation, adjust the support frame to the appropriate size to reduce damage to stalk crops. After adjustment, turn on the stepper motor to start the right conveyor belt 101 and left conveyor belt 102 to receive stalk crops. The crops are transported from the conveyor belt mechanism 1, pass through the outer one-way door 203, and enter the attitude adjustment shell 201. After the laser sensor 103 receives the signal of the crops entering, it controls the stepper motor 309 to rotate, which in turn drives the sub-rotating disk 301 and sub-rotating disk tray 302 to rotate 72°, so that the attitude adjustment shell 201 on the other side faces the conveyor belt mechanism 1 to receive the next crop. This operation is repeated five times. After all five attitude adjustment shells 201 on this sub-rotating disk tray 302 are loaded with crops, the large stepper motor 402 rotates, which drives the main rotating disk 407 to rotate 72°, so that the sub-rotating disk 301 on the other side rotates to the position of the sub-rotating disk 301 at the beginning of operation, and continues to receive crops. The sensor used is the Loschda LTD-06NC-TZ laser diffuse reflection sensor.

[0063] The posture adjustment shell 201 filled with five crops is rotated by a small stepper motor 305, which drives the five posture adjustment shells 201 to move inward simultaneously, forming a cylindrical cavity. At this time, the crops are still in an inclined position. The air pump 202 controls the internal air bladder to inflate, so that the crops in the five posture adjustment shells 201 are squeezed out from the inner one-way door 204 at the same time, forming five vertically close crops that fall into the material collection hole 314 of the opening and closing plate 405, completing the posture adjustment and collection work.

[0064] Afterwards, the opening and closing disc 405 rotates open, allowing the stalk crops that have completed their posture adjustment to fall onto the tray 505. The cylinder 508 adjusts the air pressure to raise the tray 505 to receive the stalk crops. The motor inside the blade holder 502 receives a signal and drives the root-cutting blade 501 to rotate, so that the root-cutting blade 501 completes the root cutting. After the root cutting is completed, the cylinder 508 adjusts the air pressure to lower the tray 505. During the descent, the baler 503 quickly completes the baling at the appropriate position. The cut and baled crops slide down the collection track 507, and the above steps are repeated to continue the work.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent structural changes made based on the content of the present utility model specification and drawings are included within the scope of the present utility model.
