Description

[0002] Garlic is one of the vegetables with large reserves and long storage period in China's vegetable cold storage industry. The time of harvesting garlic sprouts not only affects the yield and quality of garlic sprouts, but also has a great impact on the yield and quality of garlic roots. If harvested too early, the garlic sprouts are not long enough, thin and short, with low yield and poor quality, which will also affect the growth of garlic, resulting in reduced yield of garlic. If harvested too late, the fiber of garlic sprouts will increase, the quality will deteriorate, and too much nutrition in garlic seedlings will be consumed, resulting in the enlargement of garlic. Only by harvesting garlic sprouts in time and extracting them completely can both garlic sprouts and garlic achieve greater harvest.

[0065] In the following detailed disclosure, reference is made to the accompanying drawings, which illustrate specific embodiments that can be implemented. These embodiments are fully described by way of illustrations, which are part of the features. In order to enable those skilled in the art to understand and clarify the technical solution of the present invention more clearly, the embodiments described below are not limited thereto. The present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0066] This invention provides a needle-piercing garlic scape harvesting device, such as... Figures 1-21 As shown, the system includes a guiding and cutting mechanism 1, a garlic scape extraction mechanism 2, and a collecting mechanism 3. The guiding and cutting mechanism 1 includes a guide member 11 and a cutting part 12. A first channel for garlic scapes to pass through is provided between two symmetrically arranged guide members 11. The cutting part 12 includes a limiting component 121 and a needle-piercing component 122, which are respectively disposed in the two symmetrical guide members 11. The limiting component 121 includes a clamping band 1212, and a limiting groove 1213 for accommodating garlic scapes is opened on the outer periphery of the clamping band 1212. The needle-piercing component 122 includes a needle-piercing part 1224 that can move back and forth in the direction of the clamping band 1212. At least a part of the needle-piercing part 1224 can be inserted into the limiting groove 1213 to insert into the garlic scape placed in the limiting groove 1213. The garlic scape extraction mechanism 2 is used to transport the garlic scapes that have passed through the first channel to the collecting mechanism 3.

[0067] This needle-piercing garlic scape harvesting device guides the garlic scapes to the spacer assembly 121 and the needle-piercing assembly 122 via the guide member 11 of the guide cutting mechanism 1. The spacer assembly 121 confines the garlic scapes within the spacer groove 1213 of the clamping belt 1212. The needle-piercing part 1224 of the needle-piercing assembly 122 inserts into the garlic scape within the spacer groove 1213, disrupting the structure of the garlic scape and the garlic shoot, making it easier for the subsequent scape-pulling mechanism 2 to extract the garlic scape from the garlic shoot. Compared to the traditional technique of directly cutting with a blade, the needle-piercing avoids cutting the leaves, thus preventing damage to the garlic bulb. The clamping belt 1212 serves both to transport the garlic scapes and to confine them, facilitating the insertion of the needle-piercing part 1224. It fully utilizes the husk structure of the garlic scape, achieving both clamping and leaf removal, greatly improving the efficiency of garlic scape harvesting, realizing automatic harvesting, and solving the problem of time-consuming and labor-intensive garlic scape harvesting.

[0068] The needle type garlic sprout harvesting device guides the garlic sprout to the first channel through the guide 11, the garlic sprout enters the limiting groove 1213 of the seedling clamping belt 1212, the seedling clamping belt 1212 rotates to drive the garlic sprout to move, and in this process, the garlic sprout is always located in the limiting groove 1213, which facilitates the insertion of the needle part 1224 into the garlic sprout in the limiting groove 1213, and the position of the garlic sprout is kept stable during the needle insertion to prevent the garlic sprout from being displaced to cause the needle insertion failure.

[0069] It can be understood that the limiting groove 1213 can be a cylinder, and the inner diameter of the limiting groove 1213 is slightly larger than the outer diameter of the garlic sprout, the limiting groove 1213 is vertically arranged on the seedling clamping belt 1212 to adapt to the growth direction of the garlic sprout, the limiting groove 1213 can accommodate the garlic sprout and limit the movement of the garlic sprout, thereby limiting the garlic sprout during the conveying process and improving the success rate of needle insertion. The seedling clamping belt 1212 can be a rubber belt, which has the characteristics of wear resistance, tear resistance and puncture resistance.

[0070] Among them, the two guides 11 arranged in pairs are provided with opposite openings 112, the limiting assembly 121 is arranged on one guide 11, and the needle assembly 122 is arranged on the other guide 11, part of the limiting assembly 121 is located in the first channel through the opening 112, and part of the needle assembly 122 can enter the first channel through the opening 112.

[0071] Further, part of the seedling clamping belt 1212 can be located in the first channel through the opening 112, so that part of the limiting groove 1213 can be located in the first channel; further, at least part of the needle part 1224 can enter the first channel through the opening 112 during the reciprocating process, so that the needle part 1224 can enter the limiting groove 1213 and insert into the garlic sprout.

[0072] It can be understood that the shape of the needle part 1224 can be conical, such as a pyramid, a cone or the like, the cross-sectional area of the needle part 1224 gradually increases in the direction away from the seedling clamping belt 1212, and the end of the needle part 1224 towards the seedling clamping belt 1212 is relatively sharp, which facilitates the insertion into the garlic sprout. By increasing the contact area between the conical structure and the inside of the garlic sprout, the internal structure of the garlic sprout at the insertion position is damaged, which facilitates the subsequent extraction of the garlic sprout.

[0073] At the same time, the needle part 1224 performs needle insertion on the garlic sprout without damaging the leaf structure, which can ensure the integrity of the leaf and reduce the influence of leaf damage on the growth of garlic.

[0074] In one implementation manner, as shown in Figures 7-10As shown, the limiting assembly 121 further comprises a guide surface 111 located at one end of the garlic sprout entering direction, and the guide surface 111 converges to the first channel direction, which is used to guide the garlic sprout into the first channel.

[0075] The guide surface 111 is located in the garlic sprout entering direction, i.e. the advancing direction of the needle type garlic sprout harvesting device. The guide surface 111 can be an arc surface or a plane. In the garlic sprout entering direction, the distance between the two guide surfaces 111 gradually decreases, which is more convenient for the garlic sprout to enter between the two guide surfaces 111 and be gathered into the first channel, thereby improving the coverage area of harvesting and the efficiency of automatic harvesting. Moreover, the garlic sprouts are gathered into a first channel with a smaller width, which is convenient for subsequent needle operation. It can be understood that the width of the first channel is greater than the diameter of a garlic sprout.

[0076] The embodiment provides a style of the guide 11, specifically, the overall length of the guide 11 is 600mm-800mm, the overall width is 100mm-150mm, and the overall height is 400mm-500mm; the height of the guide surface 111 is 350mm-400mm, the length of the guide surface 111 is 250mm-350mm, and the arc of the guide surface is 300mm-500mm; the length of the opening 112 is 150mm-550mm, and the height of the opening 112 is 20mm-200mm.

[0077] In an implementable manner, as shown in Figure 9 , Figure 12 and Figure 13 , the limiting assembly 121 comprises at least two first transmission rollers 1211, and the at least two first transmission rollers 1211 are sleeved with a seedling clamping belt 1212.

[0078] It can be understood that the seedling clamping belt 1212 is sleeved on the at least two first transmission rollers 1211, and the first transmission roller 1211 is driven to rotate by the third motor 53, thereby driving the seedling clamping belt 1212 to rotate. The moving direction of the seedling clamping belt 1212 located in the first channel is consistent with the garlic sprout entering direction, i.e. opposite to the advancing direction of the needle type garlic sprout harvesting device.

[0079] The embodiment provides a type of limiting component 121, in particular, the thickness of the seedling clamping belt 1212 is 15mm-30mm, a limiting groove 1213 is punched at a certain distance, the interval between two adjacent limiting grooves 1213 is consistent, the interval can be 30mm-50mm, the inner diameter of the limiting groove 1213 is 6mm-10mm, preferably 7mm-9mm, so as to clamp the garlic sprouts, and the plurality of limiting grooves 1213 are uniformly distributed on the outer circumferential side of the seedling clamping belt 1212. The radius of the first transmission roller 1211 is 15mm-25mm, and the height is 15mm-30mm. The height of the first transmission roller 1211 is correspondingly arranged with the seedling clamping belt 1212, and the first transmission roller 1211 further comprises a sheet for limiting the upper and lower ends of the seedling clamping belt 1212, so as to limit the axial displacement of the seedling clamping belt 1212 and prevent the belt from being off.

[0082] Among them, the rhizome pushing member 123 can be arranged to further guide the garlic rhizome in the first channel into the limiting groove 1213, by arranging the pushing piece 1231 with the bending part, the interval of the pushing piece 1231 towards the direction of the garlic rhizome to be harvested is large, which can cover the width of the first channel, and the garlic rhizome entering the first channel is all guided into the limiting groove 1213.

[0083] Further, as shown in Figure 14 and Figure 15 , the pushing piece 1231 has a bending part, and the shape of the pushing piece 1231 can be an arc surface or a plane, or a combination thereof, which can realize the turning of the garlic rhizome into the limiting groove 1213.

[0084] Further, as shown in Figure 14 and Figure 15 , the bending part protrudes towards the needle assembly 122, so as to increase the space for the garlic rhizome to enter and facilitate the guidance of the garlic rhizome into the limiting groove 1213.

[0085] It can be understood that, as shown in Figure 9As shown, the poking piece 123 is arranged on the guide piece 11 opposite to the limiting assembly 121, i.e. on the guide piece 11 where the needle assembly 122 is arranged, and the needle part 1224 is located on one side of the free end of the poking piece 123, i.e. the needle part 1224 is located on the side of the poking piece 123 away from the advancing direction of the device, and the projection of the needle part 1224 on the vertical plane is less than 20 mm apart from the projection of the poking piece 123 on the vertical plane, preferably less than 10 mm, so that after the poking piece 123 pokes the garlic shoot into the limiting groove 1213, the needle part 1224 can quickly insert into the garlic shoot, greatly improving the success rate of needle cutting.

[0086] Further, the poking piece 123 can further include a connecting rod connected with the guide piece 11, and the poking piece 123 is arranged on the connecting rod, and a part of the poking piece 123 passes through the opening 112 and is located in the first channel. The fixed end of the poking piece 123 is connected with the connecting rod, the free end of the poking piece 123 extends to the direction of the seedling clamping belt 1212, and the distance between the free end of the poking piece 123 and the seedling clamping belt 1212 is less than the diameter of a garlic shoot, so that the garlic shoot cannot pass between the poking piece 123 and the seedling clamping belt 1212, and then enters the limiting groove 1213 along the arc of the poking piece 123.

[0087] In an implementation manner, as shown in Figures 16-18 The needle assembly 122 further includes a housing 1221, a crank rocker structure 1222 and a connecting rod 1223, the crank rocker structure 1222 is arranged in the housing 1221, the first end of the connecting rod 1223 is connected with the crank rocker structure 1222, and the second end of the connecting rod 1223 is connected with the needle part 1224.

[0088] It can be understood that the crank rocker structure 1222 is arranged in the housing 1221, the fourth motor 54 drives the needle part 1224 to move back and forth through the crank rocker structure 1222 and the connecting rod 1223, the needle part 1224 moves to the direction of the seedling clamping belt 1212 until it is inserted into the limiting groove 1213, and returns to the original position after the garlic shoot is inserted into the limiting groove 1213, and the needle part 1224 repeatedly moves to the direction of the seedling clamping belt 1212 until it is inserted into the next limiting groove 1213 which moves to the position opposite to the needle part 1224.

[0089] Further, as shown in Figures 16-18 The housing 1221 is provided with a clamping groove for limiting the movement of the connecting rod 1223 to the direction of the seedling clamping belt 1212, and the housing 1221 is provided with a through hole, and the connecting rod 1223 is arranged in the through hole, and the needle part 1224 is located outside the housing 1221.

[0091] The embodiment provides a style of the limiting assembly 121 and the needle pricking assembly 122, specifically, the thickness of the seedling clamping belt 1212 is 20 mm, the interval between two adjacent limiting grooves 1213 is 40 mm, the diameter of the limiting groove 1213 is 8 mm, the radius of the first transmission roller 1211 is 20 mm, the height is 20 mm, the rated power of the third motor 53 is 0.7 W, the rated voltage is 3 V, the output rotating speed is 350 r / min, and the output torque is 0.2 N·m; the stroke H of the crank rocker structure 1222 is 40 mm, the crank is a disc with a radius of r, the end of the sliding block is a needle-shaped cutter, the connecting rod is l, the formula is 1+r-(1-r)=40 mm, r=20 mm, the total length of the needle pricking box is 100 mm, the connecting rod l=60 mm, the total length of the sliding block is 40 mm, the total length of the needle-shaped cutter is 20 mm, the rated power of the fourth motor 54 is 75 W, the rated voltage is 30 V, the output rotating speed is 18000 r / min, and the output torque is 0.2 N·m.

[0092] In an implementation manner, as shown in Figures 1-4 The garlic sprout extracting mechanism 2 includes a pair of garlic sprout conveying assemblies 21, and a second channel is formed between the two garlic sprout conveying assemblies 21, used for clamping the garlic sprouts passing through the first channel, extracting the garlic sprouts, and conveying the garlic sprouts to the collecting mechanism 3.

[0093] It can be understood that after the garlic sprouts pass through the first channel for needle pricking treatment, the garlic sprouts are extracted by the garlic sprout extracting mechanism 2, clamped by the two garlic sprout conveying assemblies 21, and conveyed to the collecting mechanism 3 through the second channel for centralized collection.

[0094] As shown in Figure 20 and Figure 21 The garlic sprout conveying assembly 21 includes a garlic sprout conveying belt 212 and at least two second transmission rollers 211, the garlic sprout conveying belt 212 is sleeved on the at least two second transmission rollers 211, and the garlic sprout conveying belt 212 is arranged in an inclined manner and used to drive the garlic sprouts to move upward.

[0095] It can be understood that the second motor 52 is connected with the second transmission roller 211 to drive the second transmission roller 211 to roll and drive the garlic sprout belts 212 to rotate. The garlic sprout belts 212 are oppositely arranged, and the garlic sprout belts 212 are obliquely arranged. The end of the garlic sprout belts 212 close to the collecting mechanism 3 is higher than the end of the garlic sprout belts 212 close to the guiding cutting mechanism 1. The angle between the garlic sprout belts 212 and the horizontal plane can be 20°-60°, and preferably 25°-35°. The angle can ensure the supporting capacity of the flower bud, so as to avoid the flower bud from falling off the garlic sprout belts 212. The two garlic sprout belts 212 hold the garlic sprouts and pull the garlic sprouts upward. The distance between the two garlic sprout belts 212 can be the same as or slightly larger than the diameter of a garlic sprout. In the conveying process, the flower bud at the top of the garlic sprout can prevent the garlic sprout from falling off the garlic sprout belts 212.

[0096] It can be understood that the garlic sprout belts 212 are located above the cutting part 12. The projection of a part of the garlic sprout belts 212 in the horizontal direction is within the range of the cutting part 12, and the projection of a part of the garlic sprout belts 212 in the horizontal direction is within the range of the collecting mechanism 3. The garlic sprout can pass through the cutting part 12 first and then enter the second channel, or enter the second channel first.
