[0002] A clamping device is a common device for realizing the picking of items, which is widely used not only in the industrial production field but also in the agricultural field. For example, when carrying out the mechanized picking of garlic bolts, a clamping device is needed to extract the garlic bolts from the garlic plants. The existing clamping devices generally use a comb-like structure to realize the picking of garlic bolts.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0047] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0048] As an embodiment of the present invention, please refer to Figures 1-4, a drum-type clamping device, comprising a bolting mechanism 100 and a clamping mechanism 200. The bolting mechanism 100 is installed on the body of the equipment, and the clamping mechanism 200 is installed on the bolting mechanism 100. The bolting mechanism 100 includes a drum shaft 101, a slide rod 102, a guiding transmission mechanism, and a drum 112. The drum shaft 101 is rotatably installed on the body of the equipment through a drum shaft support seat 111. One end of the drum shaft 101 is provided with a drum shaft driving wheel 110 for connecting to a power system, and the power system is drivingly connected to the drum shaft driving wheel 110 to drive the drum shaft 101 to rotate. The number of drum shaft support seats 111 is not limited. Preferably, there are two drum shaft support seats 111 in total, and the drum shaft 101 is rotatably installed on the body of the equipment through two spaced drum shaft support seats 111. The drum 112 is fixedly installed outside the drum shaft 101. The slide rod 102 is located inside the drum 112 and is connected to the drum shaft 101 through a guiding transmission mechanism. The slide rod 102 is parallel to the drum shaft 101. The drum shaft 101 drives the slide rod 102 to rotate around the drum shaft 101 through the guiding transmission mechanism, and the guiding transmission mechanism controls the slide rod 102 to continuously approach or move away from the drum shaft 101 when rotating around the drum shaft 101. The clamping mechanism 200 is installed on the slide rod 102, and the drum 112 is provided with an avoidance hole for the clamping jaws of the clamping mechanism 200 to pass through. A clamping jaw chute 113 for limiting the clamping jaws is also provided at the avoidance hole of the drum 112. When the power system drives the drum shaft 101 to rotate through the drum shaft driving wheel 110, the drum shaft 101 rotates, and then drives the slide rod 102 to rotate around the drum shaft 101 through the guiding transmission mechanism. When the slide rod 102 rotates around the drum shaft 101, the distance between the axis of the slide rod 102 and the axis of the drum shaft 101 is constantly changing, constantly increasing or decreasing, that is, the slide rod 102 is constantly approaching or moving away from the drum shaft 101.

[0049] The clamping mechanism 200 includes a connecting ring 201, a scissor-type mechanism and a clamping plate 209. The connecting ring 201 is sleeved on the slide bar 102. The connecting ring 201 is hingedly connected to the scissor-type mechanism through a connecting ring pin 202. The other end of the scissor-type mechanism is hingedly installed with two clamping plates 209 through a clamping plate pin 210. The two clamping plates 209 are arranged opposite to each other to form a clamping claw. The scissor-type mechanism is hingedly connected to the clamping claw slide groove 113 through a clamping rod pin 206. The clamping plate 209 passes through the avoidance The hole is extended out of the drum 112, and the two ends of the clamping rod pin 206 extend and extend into the clamping claw slot 113. The length direction of the clamping claw slot 113 is parallel to the axial direction of the drum shaft 101. The clamping claw slot 113 limits the distance between the clamping rod pin 206 and the drum shaft 101, so that the clamping rod pin 206 cannot move toward the drum shaft 101 or away from the drum shaft 101, and further, the clamping plate 209 cannot move toward the drum shaft 101 or away from the drum shaft 101. The number of the clamping claw slots 113 is the same as the number of the slide bar 102, both of which are four, and the two correspond one to one. The two clamping mechanisms 200 on the slide bar 102 pass through the avoidance holes opened on the drum 112 and are limited by the corresponding clamping claw slots 113.

[0050] As the roller shaft 101 rotates, the distance between the slide bar 102 and the roller shaft 101 changes continuously, thereby driving the distance between the connecting ring 201 and the roller shaft 101 to change continuously. Due to the limiting effect of the clamping claw slide groove 113, the distance between the clamping plate 209 and the roller shaft 101 cannot change, so that the scissor-type structure continuously extends or contracts, thereby driving the two clamping plates 209 to move closer to or away from each other, thereby achieving the clamping and putting down of objects.

[0051] As an embodiment of the present invention, please refer to Figures 1-3 The guide transmission mechanism includes a slide rod sleeve 103, a slide rod toggle plate 104, a slide rod inner guide plate 105, a slide rod outer guide plate 106 and a connecting bridge 107. The slide rod inner guide plate 105 is rotatably mounted on the roller shaft 101 through a bearing. The slide rod inner guide plate 105 is also fixedly connected to the body of the device through a connecting piece 114, so that the slide rod inner guide plate 105 can rotate without rotating with the rotation of the roller shaft 101. When the roller shaft 101 rotates, the slide rod inner guide plate 105 is stationary, and relative movement can be achieved between the two. The specific structure of the connecting piece 114 is not limited. Preferably, the connecting piece 114 is an I-shaped fixing frame.

[0052] The middle part of the outer guide disc 106 of the slide bar is a through hole, and the outer guide disc 106 of the slide bar is arranged outside the roller shaft 101 through the through hole in the middle. The inner guide disc 105 of the slide bar and the outer guide disc 106 of the slide bar are in the same plane. The inner guide disc 105 of the slide bar and the outer guide disc 106 of the slide bar are fixedly connected through a connecting bridge 107. A gap with a uniform width is left between the outer edge of the inner guide disc 105 of the slide bar and the inner edge of the outer guide disc 106 of the slide bar. The gap forms a guide track 115 for the slide bar sleeve 103 to slide. Grooves matching the outer edge of the inner guide disc 105 of the slide bar and the inner edge of the outer guide disc 106 of the slide bar are provided on the slide bar sleeve 103, so that the slide bar sleeve 103 can roll along the guide track 115. During the process of the slide bar sleeve 103 rolling along the guide track 115, the connecting bridge 107 can avoid the slide bar sleeve 103 and does not affect the movement of the slide bar sleeve 103. By setting the shapes of the outer edge of the inner guide disc 105 of the slide bar and the inner edge of the outer guide disc 106 of the slide bar, the guide track 115 is not a regular circular track. That is to say, the distances between different parts of the guide track 115 and the roller shaft 101 are not equal. When the slide bar sleeve 103 rolls along the guide track 115, the distance between the slide bar sleeve 103 and the roller shaft 101 is constantly changing, constantly becoming larger or smaller. The specific shape of the guide track 115 is not limited and can be an ellipse or other regular and irregular figures, as long as it can cooperate with the clamping mechanism 200 to realize the clamping of items.

[0053] The inner guide disc 105 of the slide bar, the outer guide disc 106 of the slide bar and the connecting bridge 107 cooperate to form a slide bar guide disc. There are two slide bar guide discs in total, and they are installed on the roller shaft 101 at intervals. The number of the connecting bridges 107 is not limited. Preferably, there are two connecting bridges 107 in total, and they are installed on the slide bar guide disc at intervals. The slide bar 102 is parallel to the roller shaft 101. Slide bar sleeves 103 are fixedly installed at both ends of the slide bar 102, and the slide bar 102 is rotationally installed between the two slide bar guide discs through the slide bar sleeves 103 at its two ends.

[0054] The slide bar toggle plate 104 is fixedly installed on the roller shaft 101, and the slide bar toggle plate 104 is located between the two slide bar guide plates. Since the slide bar toggle plate 104 is fixedly connected to the roller shaft 101, the slide bar toggle plate 104 will rotate with the rotation of the roller shaft 101. A strip-shaped toggle hole for the slide bar 102 to pass through is opened on the slide bar toggle plate 104, and the length direction of the strip-shaped toggle hole extends toward the axis of the roller shaft 101. The slide bar 102 passes through the corresponding strip-shaped toggle hole. By setting the toggle hole to a strip shape, the slide bar 102 can have a certain degree of freedom in the length direction of the toggle hole; the roller 112 is fixedly sleeved and installed outside the slide bar toggle plate 104. There is no limit to the number of the slide bar toggle plates 104. Preferably, there are two slide bar toggle plates 104, which are installed on the roller shaft 101 at intervals and are located between the two slide bar guide plates. By providing two slide bar toggle plates 104, the slide bar 102 can be toggled more stably.

[0055] There is no limit to the number of the slide bars 102. Preferably, there are four slide bars 102, and the four slide bars 102 are evenly arranged around the roller shaft 101. Each slide bar toggle plate 104 is provided with four strip-shaped toggle holes corresponding to the slide bars 102. Eight slide bar sleeves 103 are provided, which are respectively installed at the two ends of the four slide bars 102. There is no limit to the number of clamping mechanisms 200 provided on each slide bar 102. Preferably, two clamping mechanisms 200 are arranged on each slide bar 102 at intervals, and the two clamping mechanisms 200 can clamp items in two adjacent rows at the same time.

[0056] When the power system drives the drum shaft 101 to rotate through the driving wheel 110 of the drum shaft, since the slide bar dial 104 is fixedly connected to the drum shaft 101, the slide bar dial 104 will rotate with the rotation of the drum shaft 101. Since the slide bar 102 passes through the strip-shaped dialing hole on the slide bar dial 104, the slide bar dial 104 will drive the slide bar 102 to rotate around the drum shaft 101. Since the slide bar guide disk is fixed to the body of the device and does not rotate with the rotation of the drum shaft 101, during the rotation of the slide bar 102 around the drum shaft 101, the slide bar sleeve 103 will roll along the guide track 115 on the slide bar guide disk, providing a guiding function for the rotation of the slide bar 102 around the drum shaft 101. The guide track 115 is not a regular circular track, which will cause the distance between the slide bar sleeve 103 and the drum shaft 101 to be constantly changing, and further drive the distance between the slide bar 102 and the drum shaft 101 to be constantly changing, continuously increasing or decreasing. The strip-shaped dialing hole on the slide bar dial 104 provides sufficient freedom for the slide bar 102 in the length direction of the dialing hole and will not affect the change in the relative distance between the slide bar 102 and the drum shaft 101. With the rotation of the drum shaft 101, the distance between the slide bar 102 and the drum shaft 101 is constantly changing, and further drives the distance between the connecting ring 201 and the drum shaft 101 to be constantly changing. Due to the limiting effect of the jaw chute 113, the distance between the clamping plate 209 and the drum shaft 101 cannot change, causing the scissor structure to continuously extend or contract, thereby driving the two clamping plates 209 to approach or move away from each other, realizing the clamping and releasing of the item.

[0057] As an embodiment of the present invention, please refer to Figure 4 , the scissor mechanism includes a left connecting rod 203, a right connecting rod 204, a jaw pin 206, a left jaw rod 207 and a right jaw rod 208. The connecting ring 201 is hingedly connected to the left connecting rod 203 and the right connecting rod 204 through a connecting ring pin 202. The other end of the left connecting rod 203 is hingedly connected to the right jaw rod 208 through a left connecting rod pin 205. The other end of the right connecting rod 204 is hingedly connected to the left jaw rod 207 through a right connecting rod pin 211. Pin holes are provided in the middle of both the left jaw rod 207 and the right jaw rod 208, and the jaw pin 206 passes through the pin holes to hingedly connect the left jaw rod 207 and the right jaw rod 208. The two clamping plates 209 are respectively hingedly installed at the ends of the left jaw rod 207 and the right jaw rod 208 through clamping plate pins 210. The two clamping plates 209 are oppositely arranged to form a jaw for clamping garlic bolts. The clamping plates 209 on the left jaw rod 207 and the right jaw rod 208 can rotate slightly around the clamping plate pin 210, so that the left jaw rod 207 and the right jaw rod 208 can better wrap around items of different thicknesses.

[0058] A rubber layer is further provided on the clamping plate 209, and the rubber layer is located on one side of the two clamping plates 209 facing each other. With this arrangement, when the clamping jaws formed by the two clamping plates 209 clamp an object, the rubber layer can reduce abrasion on the surface of the object.

[0059] As an embodiment of the present invention, please refer to Figure 5 and Figure 7 , a garlic bolt harvester based on a drum-type clamping device, comprising a bolting mechanism 100, a clamping mechanism 200, a power system 700 and a machine body 800. The clamping mechanism 200 is installed on the bolting mechanism 100. The clamping mechanism 200 is used for clamping garlic bolts, and the bolting mechanism 100 is used to cooperate with the clamping mechanism 200 to extract the garlic bolts. The machine body 800 includes a frame 801. The bolting mechanism 100 and the power system 700 are both installed on the frame 801. The power system 700 is drivingly connected to the bolting mechanism 100 and indirectly drives the clamping mechanism 200 through the bolting mechanism 100, thereby driving the coordinated operation of the bolting mechanism 100 and the clamping mechanism 200 to realize the extraction of the garlic bolts;

[0060] The garlic bolt harvester further includes a needle-pricking mechanism 400, and the needle-pricking mechanism 400 is fixedly installed on the frame 801. The needle-pricking mechanism 400 includes a support plate 401, a bolt-pricking drive wheel shaft 402, a bolt-pricking drive wheel 403, a bolt-pricking connecting rod 410 and a bolt-pricking needle 411. The support plate 401 is fixedly installed on the frame 801. The bolt-pricking drive wheel shaft 402 is rotatably installed on the support plate 401 through a bearing. The bolt-pricking drive wheel 403 is fixedly installed on the bolt-pricking drive wheel shaft 402. The power system 700 is drivingly connected to the bolt-pricking drive wheel 403 to drive the rotation of the bolt-pricking drive wheel shaft 402. A sliding hole matching the bolt-pricking connecting rod 410 is formed on the support plate 401. The bolt-pricking connecting rod 410 is slidably installed on the support plate 401 through the sliding hole. The bolt-pricking drive wheel shaft 402 is connected to the bolt-pricking connecting rod 410 through a bolt-pricking transmission mechanism to drive the bolt-pricking connecting rod 410 to reciprocally slide along the sliding hole. The other end of the bolt-pricking connecting rod 410 is provided with a bolt-pricking needle 411. Through the reciprocating movement of the bolt-pricking connecting rod 410, the reciprocating movement of the bolt-pricking needle 411 is driven, thereby cutting off the garlic bolts in the garlic plants and reducing the bolting resistance.

[0061] As an embodiment of the present invention, please refer to Figure 7, the bolting mechanism includes a first-stage bevel gear 404, a second-stage bevel gear 405, a bevel gear shaft 406, an eccentric wheel 407, a fish-eye connecting rod 408 and a bolting pin 409. The first-stage bevel gear 404 is fixedly installed on the bolting drive wheel shaft 402. The bevel gear shaft 406 is rotatably installed on the support plate 401 through bearings. One end of the bevel gear shaft 406 is fixedly installed with the second-stage bevel gear 405, and the second-stage bevel gear 405 meshes with the first-stage bevel gear 404. The other end of the bevel gear shaft 406 is fixedly installed with the eccentric wheel 407. The eccentric wheel 407 is provided with a protruding pin column, and one end of the fish-eye connecting rod 408 is rotatably installed on the eccentric wheel 407 through the cooperation of the fish-eye hole and the pin column. The other end of the fish-eye connecting rod 408 is hingedly connected to the bolting connecting rod 410 through the bolting pin 409.

[0062] There are two bolting mechanisms 400 in total, and they are symmetrically installed on the left and right sides inside the frame 801. The two bolting mechanisms 400 can simultaneously operate on two adjacent rows of garlic plants, cut off the garlic bolts inside the garlic plants, and reduce the bolting resistance.

[0063] When the bolting mechanism 400 works, the power system 700 drives the bolting drive wheel 403 to rotate, so as to drive the bolting drive wheel shaft 402 to rotate. When the bolting drive wheel shaft 402 rotates, it drives the first-stage bevel gear 404 to rotate. Due to the meshing of the second-stage bevel gear 405 and the first-stage bevel gear 404, the bevel gear shaft 406 is driven to rotate by the second-stage bevel gear 405, and then the eccentric wheel 407 is driven to rotate. When the eccentric wheel 407 rotates, through the cooperation of the pin column and the fish-eye connecting rod 408, the bolting connecting rod 410 is driven to make a reciprocating motion along the sliding hole, and then the bolting needle 411 is driven to make a reciprocating motion, so as to cut off the garlic bolts inside the garlic plants and reduce the bolting resistance.

[0064] As an embodiment of the present invention, please refer to Figure 5 , Figures 8-9 , a garlic bolt harvester further includes a diversion mechanism 500 for gathering garlic plants. The diversion mechanism 500 includes a first-stage diversion plate and a second-stage diversion plate. The first-stage diversion plate is fixedly installed on the frame 801. The first-stage diversion plate is composed of two symmetrically arranged first-stage diversion pieces. The two first-stage diversion pieces cooperate to form a space structure with a wider front and a narrower rear, so as to gather garlic plants. Specifically, the front ends of the two first-stage diversion pieces are bent outward, so as to form a space structure with a wider front and a narrower rear. The second-stage diversion plate is composed of two symmetrically arranged second-stage diversion pieces. The second-stage diversion pieces are fixedly installed on the first-stage diversion pieces and are located between the two first-stage diversion pieces. The two second-stage diversion pieces cooperate to further form a space structure with a wider front and a narrower rear, which can perform secondary gathering and guiding on garlic plants. Specifically, the front ends of the two second-stage diversion pieces are bent outward and butt-jointed and fixed to the inner sides of the first-stage diversion pieces, so as to form a space structure with a wider front and a narrower rear and realize the smooth transition between the second-stage diversion pieces and the first-stage diversion pieces.

[0065] When the garlic bolt harvester is moving for operation, through the cooperation of the first-stage deflector and the second-stage deflector, the first-stage deflector gathers the garlic plants, and the second-stage deflector performs secondary gathering and guiding on the garlic plants. Through the two-stage gathering and guiding, the garlic plants can move relative to the garlic bolt harvester within the range defined by the deflector mechanism 500. The deflector mechanism 500 provides a guiding channel for the garlic plants, facilitating the accurate cutting of the garlic bolts inside the garlic plants by the needle punching mechanism 400 and the accurate clamping of the garlic bolts by the clamping mechanism 200.

[0066] There are two deflector mechanisms 500 in total, which are symmetrically installed on the left and right sides inside the frame 801. The two deflector mechanisms 500 can perform deflector operations on two adjacent rows of garlic plants, thus cooperating with the corresponding clamping mechanism 200 and the needle punching mechanism 400. Correspondingly, since there are two deflector mechanisms 500, there are two first-stage deflectors, namely the left first-stage deflector 501 and the right first-stage deflector 503, and two second-stage deflectors, namely the left second-stage deflector 502 and the right second-stage deflector 504.

[0067] The garlic bolt harvester further includes a correction mechanism 600 for gathering the garlic bolts. The correction mechanism 600 is fixedly installed on the frame 801 and is located directly above the deflector mechanism 500. The correction mechanism 600 corresponds to the deflector mechanism 500 in position. The correction mechanism 600 includes a first-stage correction plate and a second-stage correction plate. Both the first-stage correction plate and the second-stage correction plate are fixedly installed on the frame 801. There is a gap between the first-stage correction plate and the second-stage correction plate, and they cooperate to form a space structure that is wider at the front and narrower at the rear. Specifically, the front ends of the first-stage correction plate and the second-stage correction plate both bend outward to be away from each other, increasing the distance between the front ends of the first-stage correction plate and the second-stage correction plate, thus forming a space structure that is wider at the front and narrower at the rear.

[0068] When the garlic bolts pass through the correction mechanism 600, through the cooperation of the first-stage correction plate and the second-stage correction plate, the garlic bolts can be gathered. Moreover, the support provided by the sides of the first-stage correction plate and the second-stage correction plate to the garlic bolts can straighten the garlic bolts that are inclined and bent due to gravity to a certain extent, enabling the garlic bolts to maintain a vertical state when passing through the correction mechanism 600. At the same time, due to the size and structure settings of the correction mechanism 600, the leaves of the garlic plants can be diverted outside the correction mechanism 600, thereby improving the clamping accuracy of the clamping mechanism 200 and avoiding the clamping mechanism 200 from clamping the leaves of the garlic plants, reducing the damage to the garlic plants.

[0069] There are two correcting mechanisms 600, which are symmetrically installed on the left and right sides of the frame 801 and are respectively located above the two guide mechanisms 500, so that they can operate on two adjacent rows of garlic plants at the same time. The correcting mechanism 600 cooperates with the guide mechanism 500 to work. When the guide mechanism 500 gathers and guides the garlic plants, the correcting mechanism 600 gathers and straightens the garlic scapes on the garlic plants. The two correcting mechanisms 600 are respectively a left correcting mechanism 601 and a right correcting mechanism 602. The left correcting mechanism 601 includes a left primary correcting plate 603 and a left secondary correcting plate 604, and the right correcting mechanism 602 includes a right primary correcting plate 605 and a right secondary correcting plate 606.

Preferably, five plowing pieces 302 are evenly mounted on the plowing piece connecting sleeve 307, and the five plowing pieces 302 are evenly spaced around the plowing piece connecting sleeve 307.

[0072] A flexible paddle 303 is fixedly installed on one end of the paddle piece 302 away from the paddle piece connecting sleeve 307. By providing the flexible paddle 303, the paddle mechanism 300 can paddle the garlic plants through the flexible paddle 303 when working. The flexible paddle 303 has a certain elasticity and can reduce the damage to the garlic plants. The specific material of the flexible paddle 303 is not limited. Preferably, the flexible paddle 303 is a rubber sheet. The connection method between the flexible paddle 303 and the paddle piece 302 is not limited. Preferably, the flexible paddle 303 and the paddle piece 302 are fixed by bolts and nuts.

[0073] The reel blade connecting sleeve 307, the reel blade 302 and the flexible reel blade 303 cooperate to form a reel wheel. The number of the reel wheels is not limited. Preferably, two reel wheels are arranged at intervals on the reel shaft 301. The two reel wheels can simultaneously move the garlic plants in two adjacent rows, and can feed the inclined garlic plants and garlic stalks into the machine to avoid missing garlic as much as possible.

[0074] As an embodiment of the present invention, please refer to Figure 5 , Figures 10-11 A garlic sprout harvester, the power system 700 includes a driving motor 703, a driving wheel 704, a main transmission belt 705, a driven wheel 709, a primary transmission shaft 714 and a secondary transmission shaft 716, the driving motor 703 is fixedly mounted on a frame 801 through a motor mounting seat 702, the driving wheel 704 is fixedly mounted on the driving shaft 701 of the driving motor 703, the primary transmission shaft 714 and the secondary transmission shaft 716 are rotatably mounted on the frame 801 through bearing seats, and the driven wheel 704 is fixedly mounted on the primary transmission shaft 714. 9, the driving wheel 704 is connected to the driven wheel 709 through the main transmission belt 705, so as to drive the primary transmission shaft 714 to rotate; the specific types of the driving wheel 704 and the driven wheel 709 are not limited, preferably, the driving wheel 704 and the driven wheel 709 are both V-belt wheels, and correspondingly, the main transmission belt 705 is a V-belt; when the driving motor 703 is running, the driving wheel 704 is driven to rotate through the driving shaft 701, and the driving wheel 704 drives the driven wheel 709 to rotate through the main transmission belt 705, thereby driving the primary transmission shaft 714 to rotate.

[0075] A roller driving wheel 710 is also fixedly installed on the first-level transmission shaft 714. The roller driving wheel 710 is drivingly connected to the roller shaft driving wheel 110 through a roller transmission belt 711 to drive the rotation of the roller shaft 101.

Preferably, both the roller driving wheel 710 and the roller shaft driving wheel 110 are sprockets, and the corresponding roller transmission belt 711 is a chain. When the first-level transmission shaft 714 rotates, it drives the rotation of the roller driving wheel 710, and then drives the rotation of the roller shaft driving wheel 110 through the roller transmission belt 711. When the roller shaft driving wheel 110 rotates, it drives the rotation of the roller shaft 101, thereby driving the operation of the bolting mechanism 100 and the clamping mechanism 200.

[0076] A bolting driving wheel is fixedly installed on the roller shaft 101. The bolting driving wheel is drivingly connected to the bolting driving wheel 403 through a bolting transmission belt to drive the rotation of the bolting driving wheel shaft 402, and then drive the operation of the needle pricking mechanism 400. Since there are two needle pricking mechanisms 400 and two bolting driving wheels 403, two bolting driving wheels are correspondingly provided, namely a left bolting driving wheel 109 and a right bolting driving wheel 108. Similarly, two bolting transmission belts are correspondingly provided, namely a left bolting transmission belt 712 and a right bolting transmission belt 707. The specific types of the bolting driving wheel and the bolting driving wheel 403 are not limited. Preferably, both the bolting driving wheel and the bolting driving wheel 403 are sprockets, and the corresponding bolting transmission belt is a chain. When the roller shaft 101 rotates, it drives the rotation of the bolting driving wheel, and then drives the rotation of the bolting driving wheel 403 through the bolting transmission belt. When the bolting driving wheel 403 rotates, it realizes driving the operation of the needle pricking mechanism 400.

[0077] A first indirect driving wheel 706 is fixedly installed on the first-level transmission shaft 714, and a second indirect driving wheel 717 is correspondingly fixedly installed on the second-level transmission shaft 716. The first indirect driving wheel 706 is drivingly connected to the second indirect driving wheel 717 through an indirect transmission belt 715 to drive the rotation of the second-level transmission shaft 716.

Preferably, both the first indirect driving wheel 706 and the second indirect driving wheel 717 are sprockets, and the corresponding indirect transmission belt 715 is a chain.

[0078] A threshing power wheel 718 is also fixedly installed on the secondary transmission shaft 716. The threshing power wheel 718 is drivingly connected to the threshing driving wheel 304 through a threshing transmission belt 713 to drive the threshing shaft 301 to rotate. The specific types of the threshing power wheel 718 and the threshing driving wheel 304 are not limited. Preferably, both the threshing power wheel 718 and the threshing driving wheel 304 are sprockets, and the corresponding threshing transmission belt 713 is a chain. When the primary transmission shaft 714 rotates, it drives the first indirect transmission wheel 706 to rotate, and then through the cooperation of the indirect transmission belt 715 and the second indirect transmission wheel 717, it drives the secondary transmission shaft 716 to rotate.

[0079] The machine body 800 further includes a storage bin 802, traveling wheels 803, a handle 804, and a steering wheel 805. The storage bin 802 is fixed within the frame 801 and is used to accommodate the harvested garlic bolts. The traveling wheels 803 and the steering wheel 805 are fixed to the lower end of the frame 801. The handle 804 is fixedly installed on one side of the frame 801. The traveling wheels 803 and the steering wheel 805 are respectively located at the front side and the rear side of the lower end of the frame 801. The movement direction of the garlic bolt harvester is controlled through the handle 804. The frame 801 is optimized in structure, the chassis design method is optimized, and the frame 801 is heightened to provide space for the garlic plants and garlic bolts to flow into and out of the machine, avoiding the garlic being pushed down by the vehicle body and the scraping of the garlic plants, and promoting the increase of garlic yield. A traveling power wheel 305 is fixedly installed on the threshing shaft 301, and a corresponding traveling driving wheel 719 is also fixedly installed on the traveling wheel 803. The traveling power wheel 305 is drivingly connected to the traveling driving wheel 719 through a traveling transmission belt 708 to drive the traveling wheel 803 to rotate. The specific types of the traveling power wheel 305 and the traveling driving wheel 719 are not limited. Preferably, both the traveling power wheel 305 and the traveling driving wheel 719 are sprockets, and the corresponding traveling transmission belt 708 is a chain. When the threshing shaft 301 rotates, it drives the traveling power wheel 305 to rotate, and then through the cooperation of the traveling transmission belt 708 and the traveling driving wheel 719, it drives the traveling wheel 803 to rotate, realizing the movement of the garlic bolt harvester.

[0080] The garlic bolt harvester further includes a controller for controlling the operation of the drive motor 703, and an energy storage device for supplying electrical energy to the drive motor 703 through the controller. The controller can control the start, stop, and operating speed of the drive motor 703, and the energy storage device is used to supply electrical energy for the operation of the drive motor 703.

[0081] The clamping rod pin 206 of the clamping mechanism 200 can move axially along the drum shaft 101 within the clamping jaw chute 113 of the bolting mechanism 100. The position of the connecting ring 201 on the sliding rod 102 can also be manually adjusted, so as to manually adjust the spacing between the laterally adjacent clamping mechanisms 200 according to the row spacing of the garlic plants, which has high adaptability. Correspondingly, the spacing between the two reel mechanisms 300 of the reel mechanism 300 can also be manually adjusted, and the spacing between the two needle pricking mechanisms 400, the two diversion mechanisms 500, and the two correction mechanisms 600 can also be manually adjusted, so as to adapt to garlic plants with different row spacings, which has high adaptability.

[0082] When the garlic bolt harvester is working, first, the traveling wheels 803 of the garlic bolt harvester and the steering wheel 805 located at the rear of the frame 801 travel between two rows of garlic plants. There are two rows of garlic plants inside the garlic bolt harvester, and the two rows of garlic plants inside the garlic bolt harvester are to be harvested. The drive motor 703 drives the reel mechanism 300 to rotate through the transmission system. The traveling power wheel 305 on the reel mechanism 300 drives the traveling drive wheel 719 to rotate through the traveling transmission belt 708, and the traveling drive wheel 719 drives the traveling wheels 803 to move forward; the reel blades 302 and the flexible blades 303 on the reel mechanism 300 push the garlic plants into the diversion mechanism 500, and at the same time feed the garlic bolt heads into the correction mechanism 600. The left first-stage diversion plates 501 and the right first-stage diversion plates 503 in the diversion mechanism 500 are used to gather the garlic plants and reduce the missed harvesting rate of the garlic bolts; the left second-stage diversion plates 502 and the right second-stage diversion plates 504 are used to limit the movement path of the garlic plants and confine them in the gap between the left second-stage diversion plate 502 and the right second-stage diversion plate 504 of the diversion mechanism 500, which is convenient for the accurate clamping of the needle pricking mechanism 400. Considering that the bending direction of the garlic bolt head is uncertain, the correction mechanism 600 can straighten the garlic bolt and make the garlic bolt head keep a vertical state.

[0083] Due to the forward movement of the garlic bolt harvester, the garlic plants move backward relative to the frame 801.

[0084] Under the action of the transmission system, the bolting driving wheel 403 on the needle pricking mechanism 400 rotates driven by the right bolting transmission belt 707. The bolting driving wheel 403 drives the first-stage bevel gear 404 to rotate through the bolting driving wheel shaft 402. The first-stage bevel gear 404 is vertically meshed with the second-stage bevel gear 405. The second-stage bevel gear 405 drives the bevel gear shaft 406 to rotate. The eccentric wheel 407 fixed on the bevel gear shaft 406 drives the fish-eye connecting rod 408 to move, converting the rotation of the bolting driving wheel 403 into the reciprocating movement of the bolting connecting rod 410 and the bolting needle 411, so that the bolting needle 411 intermittently pricks the garlic bolts in the garlic plants.

[0085] When the garlic plant moves to the needle-pricking mechanism 400, the garlic bolt inside the plant is pricked off, reducing the resistance for the garlic bolt clamping of the subsequent clamping mechanism 200 during bolt extraction.

[0086] When the garlic plant moves to the bolt extraction mechanism 100 and the clamping mechanism 200, the bolt extraction mechanism 100 is driven by the roller drive belt 711 to rotate the drive wheel 110 of the roller shaft on the bolt extraction mechanism 100, thereby driving the bolt extraction mechanism 100 to rotate around the roller shaft 101. When the garlic bolt gradually moves to the end of the straightening mechanism 600 within the straightening mechanism 600, the sliding rod 102 on the bolt extraction mechanism 100 gradually moves along the guiding track 115 on the outer edge of the guiding disk 105 inside the sliding rod until the sliding rod 102 is at the closest position to the axis of the roller shaft 101. At this time, the distance between the sliding rod 102 and the axis of the roller shaft 101 gradually decreases, while the distance between the connecting ring 201 connected to the sliding rod 102 and the clamping rod pin 206 gradually increases, and the included angle between the left connecting rod 203 and the right connecting rod 204 decreases, thereby driving the left clamping rod 207 and the right clamping rod 208 to rotate around the clamping rod pin 206. The left clamping rod 207 and the right clamping rod 208 approach each other, and the clamping mechanism 200 gradually closes. The surface of the clamping plate 209 is attached with a rubber layer, and at the same time, the clamping plate 209 swings slightly around the clamping plate pin 210, which can well wrap and clamp the garlic bolt. When the sliding rod 102 on the bolt extraction mechanism 100 gradually moves along the guiding track 115 on the outer edge of the cam 105 until the sliding rod 102 is at the closest position to the axis of the roller shaft 101, the clamping mechanism 200 just rotates to the end of the straightening mechanism 600, and the clamping mechanism 200 remains in a fully closed state. At this time, the clamping mechanism 200 completely clamps the garlic bolt. Subsequently, due to the radius of a certain arc section on the guiding track 115 remaining unchanged and the distance between the connecting ring 201 and the clamping rod pin 206 remaining unchanged, the clamping mechanism 200 remains closed for a period of time. Driven by the rolling of the bolt extraction mechanism 100, the clamping mechanism 200 extracts the garlic bolt. When the clamping mechanism 200 rotates 90° to reach the top of the roller 112, thereafter the sliding rod 102 continues to move along the guiding track 115, the distance between the sliding rod 102 and the axis of the roller shaft 101 gradually increases, the left clamping rod 207 and the right clamping rod 208 of the clamping mechanism 200 move away from each other, the clamping mechanism 200 gradually opens, and the extracted garlic bolt falls into the storage bin 802. When the clamping mechanism 200 rotates to the lowest end of the roller 112, the clamping mechanism 200 is completely open. Then, during the process of the clamping mechanism 200 rotating from the lowest end of the roller 112 to the end of the straightening mechanism 600, it enters the next cycle, and so on in a cycle.

[0087] The clamping mechanism 200 is located in four claw chutes 113 on the roller 112 at intervals of 90°. Two symmetrical clamping mechanisms 200 are distributed in each claw chute 113 for extracting the garlic bolts on the garlic plants in adjacent rows.

[0088] Each row of the four row of clamping mechanisms 200 spaced 90° on the drum 112 clamps and releases the garlic bolts in the same manner as described above. When the two clamping mechanisms 200 in the first row rotate 90° to the top of the drum 112, the two clamping mechanisms 200 in the second row rotate to the end of the straightening mechanism 600 to fully clamp the garlic bolts. When the two clamping mechanisms 200 in the first row continue to rotate 90° to the storage bin 802, the two clamping mechanisms 200 in the first row put the clamped garlic bolts into the storage bin 802. At the same time, the two clamping mechanisms 200 in the second row rotate 90° to the top of the drum 112. The two clamping mechanisms 200 in the third and fourth rows operate in the same manner, extracting and releasing the bolts in turn, and repeating the cycle.

[0089] The two juxtaposed clamping mechanisms 200 cooperate to extract the garlic bolts in adjacent two rows at the same time, completing the harvesting of the garlic bolts in two rows.

[0090] By setting the reel mechanism 300, the garlic bolt harvester can lift and feed the inclined or lodged garlic plants into the garlic bolt harvester, thus realizing the picking of the inclined or even lodged garlic plants and avoiding missed picking as much as possible.

[0091] The bolting mechanism 100 of the garlic bolt harvester adopts a mode of multiple clamping mechanisms 200 cooperating, and can adjust the working speed according to the speed of the driving motor 703, improving the harvesting efficiency; the clamping mechanism 200 can move axially along the drum shaft 101 in the jaw chute 113 on the bolting mechanism 100, and is used to manually adjust the distance between the adjacent clamping mechanisms 200 horizontally according to the row spacing of the plants, with high adaptability.

[0092] The surface of the clamping plate 209 at the front end of the clamping mechanism 200 of the garlic bolt harvester is attached with a rubber layer, which can reduce the abrasion on the surface of the garlic bolt. The clamping plate 209 can swing slightly around the clamping plate pin 210, so that the clamping mechanism 200 can clamp garlic bolts of different thicknesses, improving the self-adaptive clamping ability of the clamping plate 209.

[0093] The straightening mechanism 600 of the garlic bolt harvester can straighten the garlic bolts, making the garlic bolts keep a vertical state. At the same time, the leaves of the garlic plants are diverted outside the straightening mechanism 600, which not only improves the clamping accuracy of the clamping mechanism 200, but also avoids the clamping mechanism 200 clamping the leaves of the garlic plants to a certain extent, reducing the impact of garlic bolt harvesting on the garlic stems and leaves.

[0094] The garlic bolt harvester adopts an electric drive mode, which can avoid the influence of excessive mechanical vibration on the clamping accuracy of the clamping mechanism 200, and at the same time can reduce the excessive disturbance to the garlic plants, alleviating the damage to the garlic plants to the greatest extent.

[0095] This garlic bolt harvester optimizes the chassis design method, raises the frame, provides space for the inflow and outflow of garlic plants and garlic bolts into and out of the machine, avoids knocking down the garlic by the vehicle body and scratching of the garlic plants, and promotes the increase of garlic yield.
