Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a garlic bolt harvester. Background Art

[0002] In the process of garlic planting and harvesting, automated harvesting technology has been widely applied. However, current automated harvesting methods usually use blades for cutting, which easily causes garlic leaves to be cut off, thereby affecting the normal growth of garlic bulbs and ultimately reducing the garlic yield.

[0003] To solve the above problems, a garlic bolt harvester with a needle-piercing cutting mechanism has emerged on the market. This mechanism pierces the garlic bolt with a needle to damage the structure of the garlic bolt and the garlic shoot, facilitating the subsequent bolt-pulling mechanism to pull out the garlic bolt from the garlic shoot. However, when using the needle-piercing cutting mechanism, there are also some deficiencies. In addition to the garlic bolt, the garlic plant also has a pseudostem. When directly piercing the garlic bolt with a needle, the pseudostem is often pierced or broken together, which not only increases the resistance of the needle piercing, easily causes the needle to deform or break after long-term work, but also damages the garlic plant and affects its continued growth. Moreover, the broken pseudostem will be collected into the recycling bin together with the garlic bolt. The broken pseudostem is inedible and needs to be manually peeled off in subsequent processing, which increases the workload and reduces the efficiency of automated harvesting. Content of the Utility Model

[0020] In some embodiments, the front ends of the guide members each have a guiding plate. Both guiding plates are longitudinally inclined to make the front end of the moving channel in a V shape that gradually narrows from front to back.

[0021] In some embodiments, the bolting mechanism includes a bolting motor, a bolting drive wheel, a bolting connecting rod, a bolting slider, and a bolting needle.

[0022] An installation plate is provided at the bottom of the guide member. The bolting motor is installed at one end of the installation plate, and the bolting slider is slidably mounted at the other end of the installation plate.

[0023] The bolting needle is longitudinally mounted on one end face of the bolting slider to extend out of the installation plate and into the moving channel.

[0024] The bolting drive wheel is coaxially mounted on the output shaft of the bolting motor. One end of the bolting connecting rod is connected to the bolting slider, and the other end is eccentrically connected to the bolting drive wheel.

Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] like Figures 1 to 2 As shown, in an illustrative embodiment of the garlic stalk picker of the utility model, the garlic stalk picker includes a frame 1, a stalk guiding mechanism 2, a stalk tying mechanism 3, a bolting mechanism 4 and a collecting mechanism 5.

[0054] The stem guiding mechanism 2, the bolting mechanism 4 and the collecting mechanism 5 are all mounted on the frame 1. The stem guiding mechanism 2 includes two symmetrically arranged guide members 21, and a moving passage 22 for the garlic stems to pass horizontally is provided between the two guide members 21. The frame 1 is equipped with a power device 6, which is in transmission connection with the bolting mechanism 4, and the stalk tying mechanism 3 is mounted on the guide member 21.

[0055] The garlic stalk picking machine further comprises a stem-cutting mechanism 7, such as Figure 3As shown in the figure, the stem-scoring mechanism 7 is located on the front side of the bolting mechanism 3. The stem-scoring mechanism 7 includes a stem-scoring driving wheel 71, a stem-scoring connecting rod 72, a stem-scoring sliding seat 73, and a stem-scoring cone head 74. The stem-scoring sliding seat 73 is slidably mounted on the guide member 21 for vertical sliding. The guide member 21 can be provided with a chute for slidably mounting the stem-scoring sliding seat 73. The stem-scoring cone head 74 is mounted on one side surface of the stem-scoring sliding seat 73 and longitudinally extends into the moving channel 22. The stem-scoring cone head 74 can be a blade. The axle of the stem-scoring driving wheel 71 is mounted on the guide member 21 and is drivingly connected to the power device 6 through a chain transmission mechanism 61. One end of the stem-scoring connecting rod 72 is connected to the stem-scoring sliding seat 73, and the other end is eccentrically connected to the stem-scoring driving wheel 71.

[0056] The power device 6 is an existing device such as a motor or an internal combustion engine that can provide power. How it drives the bolting mechanism 4 and the stem-scoring mechanism 7 through the chain transmission mechanism 61 is prior art.

[0057] The frame 1 has wheels and moves forward in the field, enabling the garlic bolt to enter the moving channel 22 through the front end and move backward along the moving channel 22 under the clamping of the bolting mechanism 4. The false stem at the top of the garlic also enters the moving channel 22 and moves horizontally at its bottom. During the movement of the garlic bolt in the moving channel 22, it first passes through the stem-scoring mechanism 7. Driven by the power device 6, the stem-scoring driving wheel 71 rotates. The stem-scoring driving wheel 71 and the stem-scoring connecting rod 72 form a crank and connecting rod mechanism, thereby driving the stem-scoring sliding seat 73 to slide up and down. The stem-scoring cone head 74 that moves up and down accordingly extends into the moving channel 22 and cuts open the garlic false stem moving at the bottom from top to bottom, thus exposing the garlic bolt root inside. The garlic bolt further moves backward along the moving channel 22. When passing through the bolting mechanism 3, the bolting needle 35 of the bolting mechanism 3 extends into the moving channel 22 and cuts off the root of the garlic bolt. During the process of the bolting mechanism 4 clamping the garlic bolt and moving it backward along the moving channel 22, the garlic bolt is lifted upward. Since the root of the garlic bolt is cut off, the garlic bolt is pulled out of the garlic. When the garlic bolt leaves the bolting mechanism 4 from the rear end, it falls into the collection mechanism 5, realizing the harvesting of the garlic bolt.

[0058] In the above-described exemplary embodiment, the garlic bolt harvester is provided with the stem-scoring mechanism 7 in front of the bolting mechanism 3, which can vertically cut open the garlic false stem to expose the garlic bolt root inside. When the bolting mechanism 3 punctures and cuts off the root of the garlic bolt, it will not puncture the garlic false stem but directly puncture the root of the garlic bolt, avoiding damage to the garlic, avoiding deformation or breakage of the puncture needle due to excessive penetration thickness, and also avoiding the false stem being cut off and being taken into the recycling bin along with the garlic bolt, avoiding an increase in the workload of peeling the false stem. Moreover, the cut-open false stem reduces its wrapping of the garlic bolt, and the resistance to pulling out the garlic bolt is smaller, enabling the bolting mechanism 4 to quickly and efficiently pull out the garlic bolt, improving the recycling efficiency, and solving the problems of the current garlic bolt harvester where the puncture needle deforms and breaks due to puncturing the false stem, causing damage to the garlic, and the subsequent need for manual peeling of the false stem.

[0059] In some embodiments, the garlic bolt harvester further includes a feeding mechanism 8, which is located above the front end of the guiding mechanism 2 and higher than the front end of the bolting mechanism 4.

[0060] The feeding mechanism 8 includes a feeding roller 81 and a garlic bolt guiding assembly. The feeding roller 81 is longitudinally installed on the frame 1 and is drivingly connected to the power device 6 through a chain transmission mechanism 61. The garlic bolt guiding assembly is vertically installed on the feeding roller 81 and is longitudinally aligned with the moving channel 22. The garlic bolt guiding assembly includes two garlic bolt guiding rods 82 arranged at longitudinal intervals.

[0061] Since the top of the garlic bolt is prone to bending, if the garlic bolt directly enters the bolting mechanism 4 in a longitudinally bent state, it is easy to make the bolting mechanism 4 clamp two sections of the top of the garlic bolt simultaneously in the longitudinal direction. However, the space width of the bolting mechanism 4 for accommodating the garlic bolt is limited, which will cause the top of the garlic bolt to be pinched off or crushed.

[0062] Driven by the power device 6, the feeding roller 81 rotates, and the two garlic bolt guiding rods 82 of the garlic bolt guiding assembly rotate accordingly. When the frame 1 moves forward, the garlic bolt first enters between the two garlic bolt guiding rods 82, and then passes over the feeding roller 81 from below. When the two garlic bolt guiding rods 82 rotate to the rear side, they move upward, so as to straighten the top of the garlic bolt upward, making it enter the bolting mechanism 4 in a straight state, being clamped and conveyed by it, thus avoiding the bent garlic bolt being pinched off or crushed by the bolting mechanism 4.

[0063] In order to improve the stability of the garlic bolt when it enters between the two garlic bolt guiding rods 82, the distance between the two garlic bolt guiding rods 82 gradually decreases from the outside to the inside, so that the entering garlic bolt is clamped by the two garlic bolt guiding rods 82. And the garlic bolt guiding rods 82 are made of elastic members, and the garlic bolt is stably clamped through their elasticity, so as to maintain stability in the longitudinal direction. When it moves over the feeding roller 81 to its rear side, it is still between the two garlic bolt guiding rods 82 and is straightened by them. In order to achieve continuous operation, multiple groups of garlic bolt guiding assemblies are arranged at intervals in the circumferential direction.

[0064] In some embodiments, the garlic bolt harvester further includes a leaf pressing mechanism 9, which is located below the bolting mechanism 4 and includes two laterally arranged leaf pressing rods 91. Both of the two leaf pressing rods 91 are inclined so that their front ends are higher than their rear ends. Both of the two leaf pressing rods 91 are fixedly installed on the frame 1 and are respectively above the corresponding guiding members 21.

[0065] When the rack 1 moves forward, the front end of the leaf pressing rod 91 first contacts the leaves of the garlic plant, causing it to slide along the bottom surface of the leaf pressing rod 91. The garlic bolt enters the space between the two leaf pressing rods 91 and thus moves smoothly backward. Since the front of the leaf pressing rod 91 is high and the rear is low, the leaf pressing rod 91 presses the leaves on both sides downward, keeping them away from the bolting mechanism 4, preventing the leaves from being clamped into the bolting mechanism 4 and causing the bolting mechanism 4 to pull out the garlic plant from the soil, and avoiding damaging the garlic accordingly.

[0066] In some embodiments, the front ends of the guiding members 21 are each provided with an introducing plate 23, and the two introducing plates 23 are both longitudinally inclined so as to make the front end of the moving channel 22 in a V shape that gradually narrows from front to back.

[0067] The front end of the moving channel 22 is in a flared mechanism, enabling the garlic bolt to easily enter the moving channel 22 from the front end and guiding the garlic bolt to move longitudinally into the middle and rear parts of the moving channel 22. The middle and rear parts of the moving channel 22 are narrower, with a width slightly larger than the outer diameter of the garlic bolt, enabling the garlic bolt to move along its axis in the middle and rear parts of the moving channel 22, thus being close to the stem cutting mechanism 7 and the bolting tying mechanism 3, ensuring that the stem cutting mechanism 7 accurately cuts open the false stem of the garlic, and ensuring that the bolting tying mechanism 3 can longitudinally penetrate the root of the garlic bolt and thus smoothly cut it off.

[0068] In some embodiments, as Figure 4 shown, the bolting tying mechanism 3 includes a bolting tying motor 31, a bolting tying transmission wheel 32, a bolting tying connecting rod 33, a bolting tying slider 34, and a bolting tying needle 35.

[0069] An installation plate 24 is arranged at the bottom of the guiding member 21. The bolting tying motor 31 is installed at one end of the installation plate 24, and the bolting tying slider 34 is slidably installed at the other end of the installation plate 24. The bolting tying needle 35 is longitudinally installed on one side end face of the bolting tying slider 34 so as to extend out of the installation plate 24 and extend into the moving channel 22. The bolting tying transmission wheel 32 is coaxially installed on the output shaft of the bolting tying motor 31, and one end of the bolting tying connecting rod 33 is connected to the bolting tying slider 34, and the other end is eccentrically connected to the bolting tying transmission wheel 32.

[0070] Driven by the bolting tying motor 31, the bolting tying transmission wheel 32 rotates. The bolting tying transmission wheel 32 and the bolting tying connecting rod 33 form a crank and connecting rod mechanism, so that the rotating bolting tying transmission wheel 32 drives the bolting tying slider 34 to move longitudinally back and forth, and the bolting tying needle 35 moves longitudinally accordingly, cutting off the root of the garlic bolt on one side of it.

[0071] Since the stalk-tying needle 35 can only pierce a hole in the garlic stalk once, the part that contacts the stalk-tying needle 35 remains connected. Therefore, when the garlic stalk moves longitudinally, the stalk-tying needle 35 needs to pierce the root of the garlic stalk several times to cut it off. The reciprocating speed and frequency of the stalk-tying needle 35 are relatively high. If the stalk-tying transmission wheel 32 is also driven by the power device 6 through the chain transmission mechanism 61, a speed reduction mechanism needs to be set in order to increase the operating frequency. At this time, the stalk-tying motor 31 is used to realize independent driving, and there is no need to set a speed reducer for speed adjustment, which simplifies the equipment structure, reduces the equipment cost and installation and manufacturing difficulty, and improves the equipment operation stability.

[0072] In some embodiments, the tufting motor 31 is located on the surface of one side of the mounting plate 24, and the tufting slider 34 is slidably installed in the slide groove 25 provided on the surface of the other side of the mounting plate 24. Since the tufting motor 31 and the tufting slider 34 are respectively located on both sides of the mounting plate 24, the tufting transmission wheel 32 and the tufting connecting rod 33 are all on the same side with the tufting slider 34, even if the movable parts are all located on the same side, it is convenient to centrally use the cover to cover the inside to avoid damage to them by external contact or collision with personnel. Multiple tufting needles 35 are arranged side by side in the horizontal direction, so that multiple positions of the garlic tufts can be pierced through in one action, and the garlic tufts can be cut quickly and neatly.

[0073] In some embodiments, Figure 5 As shown, the bolting mechanism 4 includes two transversely arranged transmission components 4'.

[0074] The transmission assembly 4' includes a transmission frame 41 fixed on the frame 1, two transmission pulleys 42 installed on the transmission frame 41 and arranged front and rear, and a synchronous belt 43 installed between the two transmission pulleys 42, and one transmission pulley 42 is connected to the power device 6 through a chain transmission mechanism 61, so that the two synchronous belts 43 of the two transmission assemblies 4' clamp the garlic sprouts and drive them to move horizontally backward.

[0075] The transmission components 4' are all inclined so as to gradually rise from the front to the back, so as to pull the garlic scapes upwards when they are moved backwards.

[0076] Driven by the power device 6, the drive pulleys 42 of the two transmission components 4' rotate, driving the two synchronous belts 43 to operate. When the garlic stalk enters the moving channel 22 horizontally, its top enters between the two transmission components 4', is clamped by the two operating synchronous belts 43, and is driven to move backward. At the same time, since the transmission component 4' is inclined, the clamped garlic stalk is pulled upward during the backward movement, thereby being pulled out of the garlic stalk.

[0077] In some embodiments, the transmission assembly 4' further includes a tensioning seat 44, one end of which is hinged on the transmission frame 41, and the other end of which is installed with a tensioning wheel 45. Multiple tensioning seats 44 are installed transversely, and tensioning springs 46 are installed between the tensioning seats 44 and the transmission frame 41. The tensioning springs 46 pull the corresponding tensioning seats 44 transversely to make the tensioning wheel 45 push the synchronous belt 43 longitudinally and make the end of the space between the two synchronous belts 43 horn-shaped.

[0078] Driven by the tension spring 46, the tension wheel 45 can tighten the synchronous belt 43 to keep the transmission pulley 42 driving it stably. The tension wheel 45 can adjust the arrangement shape of the synchronous belt 43 to make the middle sections of the two synchronous belts 43 closer together, which not only clamps the garlic stalks more firmly, but also makes it easier for the garlic stalks to enter and leave the horn-shaped spaces at both ends. The tension spring 46 can also play a buffering role, allowing the synchronous belt 43 to float in the longitudinal direction while maintaining a stable clamping force on the garlic stalk, avoiding the garlic stalks from being crushed or broken due to the clamping force applied to the garlic stalks.

[0079] In some embodiments, the collecting mechanism 5 is a collecting box with an upward opening, which is located above the rear end of the bolting mechanism 4, so that the garlic stems leaving the bolting mechanism 4 can directly fall into the collecting box to complete the picking and collection.

[0080] In some embodiments, a ground wheel 11 is installed on the frame 1, and the ground wheel 11 is connected to the power device 6 through a chain transmission mechanism 61. The power device 6 drives the bolting mechanism 4, the stem-cutting mechanism 7 and the feeding mechanism 8, and provides driving force for the ground wheel 11, so that the frame 1 can move in the field, thereby improving the convenience of moving the frame 1.

[0081] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0082] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
