Description

Technical Field

[0001] This utility model belongs to the technical field of garlic scape harvesters, and in particular relates to a self-propelled integrated machine for cutting and harvesting garlic scape stems. Background Technology

[0002] Currently, garlic scapes are still primarily harvested manually, a process that faces challenges such as high labor intensity, low efficiency, difficulty in guaranteeing quality, and high costs. Furthermore, manual harvesting makes it difficult to ensure consistent quality. Therefore, replacing manual harvesting with machinery is a reasonable option. Mechanized harvesting can, to some extent, improve the marketability and added value of garlic scapes. Thus, to reduce harvesting costs and improve efficiency and quality, there is an urgent need to develop garlic scape harvesting machines.

[0003] However, existing garlic scape harvesters have low levels of automation and low operating efficiency, requiring manual and walking operation, which increases the labor intensity of operators and affects operating efficiency. Some models perform well in sandy loam soil, but perform poorly or even cannot operate in clay loam soil. Power matching is limited, and more than 90% of garlic harvesters sold on the market are paired with small-horsepower walking tractors, while in most garlic-growing areas, the number of walking tractors is very small.

[0004] Overall, current garlic scape harvesters in China have certain shortcomings in terms of automation, mechanical performance, cost-effectiveness, technical training, and soil texture. Currently, most garlic scape harvesters in my country are simple in structure, have limited functions, and are semi-automatic with manual pushing. How to efficiently replace manual harvesting of garlic scapes remains a major challenge. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1 As shown, a self-propelled garlic scape cutting, harvesting and picking machine is characterized by comprising a frame 1, a stem cutting mechanism 2, a straightening mechanism 3, a circulating picking mechanism 4, a recycling box 5, and a walking mechanism 6; the frame 1 includes a front frame 11 and a rear frame 12. The rear frame 12 is equipped with a lifting mechanism 13 at its front end to drive the overall raising / lowering of the front frame 11. One or more stem-cutting mechanisms 2 are installed on the front frame 11 to automatically cut the garlic scapes. The number of straightening mechanisms 3 and circulating harvesting mechanisms 4 is equal to the number of stem-cutting mechanisms 2, and they correspond one-to-one in front and back positions. The straightening mechanism 3 is installed on the upper rear side of the front frame 11 and is used to push the cut garlic scapes backward to the circulating harvesting mechanism 4. The circulating harvesting mechanism 4 is installed on the rear frame 12, with its front inlet located below the straightening mechanism 3. The circulating harvesting mechanism 4 is inclined from the lower front to the upper rear and is used to transport the garlic scapes from the front inlet to the recycling bin 5. The recycling bin 5 is located on the rear side of the rear frame 12, and the outlets of each circulating harvesting mechanism 4 are aligned with the recycling bin 5. A walking mechanism 6 is installed on the rear frame 12 and is used to drive the frame 1 to move.

[0022] This embodiment uses the example of setting up two sets of stem-breaking mechanisms 2, straightening mechanisms 3, and cyclic harvesting mechanisms 4 for illustration.

[0023] The front rack 11 adopts a frame structure, which includes a first mounting bracket 111 and three U-shaped second mounting brackets 112. The first mounting bracket 111 is in the shape of a downward-facing "E", as shown below. Figure 1 , Figure 3 and Figure 4 As shown. A second mounting bracket 112 is connected to the left, middle and right sides of the first mounting bracket 111 respectively; a third mounting bracket 113 is provided on the upper rear surface of each second mounting bracket 112. These three third mounting brackets 113 are used to install the two straightening mechanisms 3. The upper surface of the third mounting bracket 113 is the mounting surface.

[0024] like Figure 2 and Figure 3 As shown, the lifting mechanism 13 employs an electric push rod 131, a guide rod 132, and a guide sleeve 133. The electric push rod 131 is vertically positioned; its fixed end is mounted on a fourth mounting bracket 121 extending horizontally forward from the front of the rear frame 12; the movable end of the electric push rod 131 is positioned higher than its fixed end, and the top of the movable end is connected to a first mounting bracket 111 via a long bolt. The guide rod 132 in the lifting mechanism 13 is vertically mounted in the middle of a second mounting bracket 112 on the side, and the guide sleeve 133 is mounted on the fourth mounting bracket 121; the guide rod 132 extends into the guide sleeve 133 to guide the movement of the front frame 11 during its ascent / descent. The guide sleeve 133 and the fixed end of the electric push rod 131 can be located on different sides of the fourth mounting bracket 121. For example, the guide sleeve 133 is located on the inner side of the fourth mounting bracket 121, and the fixed end of the electric push rod 131 is located on the outer side of the fourth mounting bracket 121.

[0025] like Figure 4 As shown, the stem-breaking mechanism 2 includes a first slotted positioning plate 21, a second slotted positioning plate 22, and a stem-breaking needle assembly 23. The slotted surfaces of the first slotted positioning plate 21 and the second slotted positioning plate 22 are positioned opposite each other. The front and rear ends of the first slotted positioning plate 21 are respectively mounted on a second mounting bracket 112 located on the side of the front frame 11 via a fifth mounting bracket 24. The fifth mounting bracket 24 is horizontally positioned, with one end connected to the second mounting bracket and the other end connected to the first slotted positioning plate 21. After installation, the slotted surface of the first slotted positioning plate 21 faces the inside of the integrated machine (i.e., the side facing where the second slotted positioning plate 22 is located). Taking the left-side stem-breaking mechanism 2 as an example, the inside here refers to the right side. Figure 5 and Figure 6As shown, the first slotted positioning plate 21 has several arc-shaped slots 211 arranged front to back, each arc-shaped slot 211 extending vertically; a long strip-shaped through hole 212 extending front to back is provided at the middle position of the first slotted positioning plate 21 in the vertical direction, the long strip-shaped through hole 212 not completely penetrating the entire first slotted positioning plate 21. The second slotted positioning plate 22 has several square slots 221 arranged front to back, each square slot 221 extending vertically. When the first slotted positioning plate 21 and the second slotted positioning plate 22 approach and contact each other, the arc-shaped slots 211 on the first slotted positioning plate 21 and the square slots 221 on the second slotted positioning plate 22 align one by one to form a garlic scape clamping area, clamping the garlic scape during stem cutting. The second slotted positioning plate 22 is equipped with a lead screw drive mechanism 25 to drive the second slotted positioning plate 22 to move closer to / away from the first slotted positioning plate 21 in the left-right direction; the lead screw drive mechanism 25 is located on the second mounting bracket 112 in the middle of the front frame 11. The stem-breaking needle assembly 23 and the second slotted positioning plate 22 are located on different sides of the first slotted positioning plate 21. Taking the left-side stem-breaking mechanism 2 as an example, the stem-breaking needle assembly 23 is located on the left side of the first slotted positioning plate 21; Figure 7 As shown, the stem-breaking needle assembly 23 is provided with multiple stem-breaking needles arranged in the front-to-back direction, and the stem-breaking needle assembly is aligned with the elongated perforation 212 in the left-to-right direction to facilitate the stem-breaking needles passing through the first slot-shaped positioning plate 21. The stem-breaking needle assembly 23 is equipped with a stem-breaking needle assembly horizontal drive mechanism to drive the stem-breaking needle assembly 23 to insert into or withdraw from the garlic scape clamping area through the elongated perforation 212 in the left-to-right direction.

[0026] In this embodiment, taking two sets of stem-breaking mechanisms 2 as an example, the horizontal drive mechanism of the stem-breaking needle group adopts a structure in which a first drive motor 231, a gear 232, and a rack 233 cooperate with each other; wherein, the first drive motor 231 is mounted on the second mounting bracket 112 located on the side, the output shaft of the first drive motor 231 is connected to the gear 232, and the gear 232 and the rack 233 mesh with each other; the rack 233 extends in the left and right direction, and one end of the rack 233 is connected to the stem-breaking needle group 23. Each second slot-shaped positioning plate 22 is equipped with a lead screw drive mechanism 25, which is used to drive the second slot-shaped positioning plate 22 to move in the left and right direction. Taking one of the lead screw drive mechanisms as an example, the lead screw nut 251 slides left and right along the lead screw 252. A sliding sleeve 253 is connected to the bottom of the lead screw nut 251. The sliding sleeve 253 is mounted on a sliding shaft 254 (the sliding shaft 254 is a smooth shaft, which facilitates the sliding sleeve 253 to slide left and right along its axis, thereby achieving motion guidance). In addition, the sliding sleeve 253 is also connected to the second slotted positioning plate 22. When the lead screw nut 251 moves left and right along the lead screw 252, it can simultaneously drive the sliding sleeve 253 and the second slotted positioning plate 22 to move in the left and right directions. The sliding shaft 254 is mounted on the second mounting bracket 112 located in the middle through the first bearing seat 255. Since the two second slotted positioning plates 22 are located on both sides of the middle second mounting bracket 112, the left and right lead screw drive mechanisms 25 in this embodiment can share a single drive source to simultaneously drive the two second slotted positioning plates 22 to move. The drive source is located between the two second slotted positioning plates 22. For example, the drive source can be driven by a combination of a second drive motor 256 and a first bevel gear steering box 257. The first bevel gear steering box 257 adopts a T-shaped structure. The output shaft of the second drive motor 256 is connected to the input end of the first bevel gear steering box 257, and the output end of the first bevel gear steering box 257 is connected to the lead screws 252 on both sides, which can simultaneously drive the lead screw nuts 251 on both sides to move closer or further apart.

[0027] When the garlic sprout enters the predetermined position of the stem-cutting mechanism 2, the lead screw drive mechanism 25 drives the second slotted positioning plate 22 to move closer to the garlic sprout. At the same time, the first drive motor 231 drives the gear 232 and rack 233 to move together, causing the stem-cutting needle group 23 to move closer to the garlic sprout until the stem-cutting needle just pierces the inner stem of the garlic sprout (i.e., the garlic scape), achieving the purpose of cutting the stem without cutting the stalk. Then, the first drive motor 231 drives the gear 232 and rack 233 to move together, causing the stem-cutting needle group 23 to withdraw from the garlic sprout. Finally, the lead screw drive mechanism 25 drives the second slotted positioning plate 22 to withdraw from the garlic sprout, completing the entire stem-cutting process.

[0028] like Figure 4As shown, the straightening mechanism 3 includes a straightening shaft 31 and a "Z"-shaped garlic sprout paddle 32. The straightening shaft 31 is arranged horizontally in the left-right direction, and its ends are mounted on the third mounting brackets 113 on both sides via second bearing seats 33. The straightening shaft 31 is equipped with a straightening shaft rotation drive mechanism for driving its rotation. The straightening shaft rotation drive mechanism is installed in the middle of the first mounting bracket 111. For example, the straightening shaft rotation drive mechanism uses a combination of a third drive motor 34 and a second bevel gear steering box 35. The second bevel gear steering box 35 has a T-shaped structure. The third drive motor 34 is located in the middle of the first mounting bracket 111, and the second bevel gear steering box 35 is mounted on the middle third mounting bracket 113 via a support plate 36. The output shaft of the third drive motor 34 is connected to the input end of the second bevel gear steering box 35, and the output end of the second bevel gear steering box 35 is connected to the straightening shaft 31, thereby simultaneously driving both straightening mechanisms 3 to perform straightening actions. The “Z”-shaped garlic scape pick 32 is composed of two L-shaped plates. The end of each L-shaped plate near the straightening shaft is fixed to the straightening shaft 31 by bolts. After the two L-shaped plates are fixed, the “Z”-shaped garlic scape pick 32 is formed.

[0029] like Figure 8 and Figure 9 As shown, the circulating harvesting mechanism 4 includes two guide plates 41, two parallel conveyor belts 42, a constraint top plate 43, and a constraint bottom plate 44. The two guide plates 41 are located below the straightening mechanism 3; they are arranged opposite each other in the left-right direction, forming a "V"-shaped converging structure with a larger opening at the front and a smaller opening at the rear; the front end of the guide plate 41 is located at the front of the rear frame 12, and the rear end of the guide plate 41 extends to the front end of the corresponding conveyor belt 42. Both conveyor belts 42 extend in the front-back direction, and the front end of each conveyor belt 42 is lower than its rear end, a design that facilitates the extraction of garlic scapes from the garlic sprouts; the surface of each conveyor belt 42 is vertically oriented, forming a garlic scape compression channel between the surfaces of the two conveyor belts 42; each conveyor belt 42 is made of PVC grass-textured conveyor belt. Each conveyor belt 42 is equipped with a fourth drive motor 45 for driving the conveyor belt 42; the fourth drive motor 45 is located at the rear of the conveyor belt 42 and is mounted on the rear frame 12 via a motor mounting bracket 46. A constraint top plate 43 and a constraint bottom plate 44 are respectively positioned above and below the garlic scape extrusion channel and extend in the front-to-back direction. The constraint top plate 43, constraint bottom plate 44, and the two conveyor belts 42 cooperate to form a pipe structure for cyclically harvesting garlic scapes. The front end of the constraint top plate 43 has an upwardly bent structure, such as... Figure 9 As shown.

[0030] The recycling bin 5 is equipped with chambers 51, the number of which is the same as the number of stem-breaking mechanisms 2. The garlic scapes enter the chambers 51 through the conveyor belt 42 in each recycling harvesting mechanism 4.

[0031] After being straightened by the straightening mechanism 3, the garlic scapes enter the circulating harvesting mechanism 4. The "V"-shaped guide plate guides the exposed part of the garlic scapes to accurately enter the inlet of the conveyor belt 42. The PVC lawn-patterned conveyor belt 42 clamps the garlic scapes with broken stems. Through the constraints of the top plate 43 and the bottom plate 44, the garlic scapes are pulled out from the false stems by moving obliquely upward through the conveyor belt 42 and finally fall into the corresponding chamber 51 of the collection box 5, thus realizing the function of continuous harvesting, conveying and collecting of garlic scapes.

[0032] like Figure 1 As shown, the walking mechanism 6 is a tracked walking structure. The tracked walking structure is characterized by its spacious support area and moderate ground pressure, easily handling soft or muddy working environments. Due to its smaller sink angle and reduced rolling resistance, the device can transmit power more efficiently. Furthermore, this tracked design not only improves the device's stability and mobility in complex terrain but also significantly reduces damage to the ground, thus protecting the working environment. In summary, this device has significant advantages in operating on soft or muddy ground.

[0033] Of course, the above description is only a preferred embodiment of the present utility model. The present utility model is not limited to the above-described embodiments. It should be noted that any equivalent substitutions or obvious modifications made by those skilled in the art under the guidance of this specification fall within the scope of this specification and should be protected by the present utility model.
