[0002] Due to differences in the ecological characteristics of different vegetables, integrated vegetable harvesting is very complex, and harvesting methods vary depending on the type of vegetable. Fast-growing leafy vegetables are generally uprooted and harvested directly, while vegetables with a high germination rate, such as chives, garlic seedlings, lettuce, and water spinach, can be harvested by leaving the roots and picking the leaves.

[0003] At present, most of China's vegetable harvesting is completed artificially, with low artificial harvesting efficiency and high labor intensity. With the increase in labor costs, the proportion of artificial harvesting costs in vegetable production costs has also risen significantly. In order to improve vegetable harvesting efficiency, reduce artificial labor intensity, increase product efficiency, and ensure the healthy and stable development of the domestic vegetable industry, several vegetable harvesting machines have appeared on the market.

[0010] Furthermore, a torsion spring is arranged at the pivot connection between the upper harvesting plate and the horizontal shaft.

[0011] Furthermore, a first return spring is disposed at the sliding connection between the upper harvesting plate and the lower harvesting plate.

[0012] Further, a first electric telescopic lever is arranged on the outer surfaces of the two side panels and near the lower center thereof, the first electric telescopic lever is rotatably connected to the side panels, the two second electric telescopic levers are fixedly attached symmetrically to the tip of the rack and near the top thereof, a first mounting frame is fixedly connected to the fixed ends of the two second electric telescopic levers, a rangefinder is fixedly attached to the underside of the first mounting frame, a hinge holder is fixedly attached to the underside of the fixed end of the second electric telescopic lever, the telescopic end of the first electric telescopic lever is rotatably connected to the hinge holder, a second mounting frame fixedly connected to the second electric telescopic lever is arranged at the telescopic end of the second electric telescopic lever, a third electric telescopic lever is fixedly attached to the underside of the second mounting frame, and a partition plate fixedly connected to the third electric telescopic lever is arranged at the telescopic end of the third electric telescopic lever.

[0013] Further, a curved ring groove is formed on an outer surface of the camshaft, and a maximum displacement D of the curved ring groove is not smaller than the width of the opening of the first U-shaped groove and the second U-shaped groove.

[0016] Furthermore, wheels capable of moving all four racks are arranged on the underside of the rack near its four corners, and a first motor capable of driving its rotation is fixedly attached to the underside of the rack corresponding to the wheels. Effect of the Invention

[0017] First, when the present invention is used to harvest vegetables, the driving wheels corresponding to the first motor can be controlled to move the entire rack, and the height of the vegetables can be measured by a distance meter. When the height of the vegetables does not reach the harvesting standard, the first electric telescopic lever is shortened to swing the side plate upward around the rack, thereby lifting the harvesting assembly upward, and the harvesting assembly is lifted upward and continues to move forward, passing over the top of the vegetables whose height does not reach the harvesting standard. When the height of the vegetables reaches the harvesting standard, the first electric telescopic lever is extended to swing the side plate downward around the rack, so that the first U-shaped groove and the second U-shaped groove are caught at the root position of the vegetables, and the vegetables that reach the harvesting standard are harvested in an appropriate manner through the harvesting assembly. This design realizes the purpose of intelligently determining the growth momentum of the vegetables and selectively harvesting them, which increases the intelligence of the present invention, ensures the maximization of the benefits of vegetable cultivation, and reduces the physical labor intensity of the workers during the harvesting work.

[0018] Second, when harvesting vegetables according to the present invention, the electric slide block is slid forward to the bottom of the camshaft, and then the third motor is controlled to rotate the camshaft, and the camshaft swings the upper harvesting plate upward through the electric slide block and the lower harvesting plate, thereby uprooting the vegetables through the first U-shaped groove and the second U-shaped groove, and then the electric slide block is slid backward to the bottom away from the camshaft, and the fourth electric telescopic lever is extended, and the pick lever is swung upward due to the extension of the fourth electric telescopic lever 30, and when the pick lever is swung upward, the third motor is used to rotate the camshaft. The upper end of the pick lever enters the corresponding curved ring groove on the outer surface of the camshaft, and the pick lever is swung back and forth left and right through the curved ring groove when the camshaft rotates, thereby realizing the left and right sliding of the lower harvesting plate and the electric sliding block. When the lower harvesting plate slides left and right, the first U-shaped groove and the second U-shaped groove slide out of alignment, and the shear force generated when the first U-shaped groove and the second U-shaped groove slide out of alignment cuts the vegetables. With this design, when harvesting vegetables, the vegetables can be uprooted and harvested directly, or the vegetables can be harvested by leaving the roots and picking the leaves.

[0019] Third, after the vegetable harvesting operation is completed, the present invention controls the extension of the third electric telescopic lever and the contraction of the second electric telescopic lever to move the partition plate backward, so that the harvested vegetables can be better transported to the conveying device in accordance with the harvesting assembly when the partition plate is moved backward, and further controls the second motor to drive the conveyor belt, which transports the harvested vegetables into the collecting box, thereby ensuring convenience during the use of the present invention.

[0020] In view of the above, the present invention can selectively harvest vegetables based on the growth vigor of the vegetables, and different harvesting methods can be adopted according to different types of vegetables, with stable usage performance and relatively good versatility.

With this design, the range finder 12 can measure the height of the vegetables, and when the height of the vegetables does not reach the harvesting standard, the first electric telescopic lever 9 can be shortened to swing the side plate 8 upward around the rack 1, thereby lifting the harvesting assembly upward to not harvest; when the height of the vegetables reaches the harvesting standard, the third electric telescopic lever 15 can be extended and the second electric telescopic lever can be shortened, thereby moving the partition plate 16 backward and cooperating with the harvesting assembly to better transport the harvested vegetables to the conveying device 6.This design realizes the purpose of intelligently determining the growth vigor of vegetables and selectively harvesting them.

[0030] As shown in Figures 1, 2, 3, 4, 5 and 6, the harvesting assembly includes a camshaft 17, which is rotatably connected to the inner surfaces of the two side plates 8 and near the lower center thereof; a third motor 18 capable of driving the rotation of the camshaft 17 is fixedly mounted on the outer surfaces of the side plates 8 and at a position corresponding to the camshaft 17; a horizontal shaft 19 fixedly connected to the side plates 8 is disposed on the inner surfaces of the two side plates 8 and near the lower ends thereof; an upper harvesting plate 20 rotatably connected to the horizontal shaft 19 is disposed on the outer surfaces of the horizontal shaft 19; a torsion spring is disposed at the rotation connection between the upper harvesting plate 20 and the horizontal shaft 19; and the torsion spring is disposed at the upper harvesting plate 20 and the horizontal shaft 19. When the upper harvesting plate 20 is not subjected to external force, the upper harvesting plate 20 is provided at its front end with a plurality of equally spaced first U-shaped grooves 21, the lower harvesting plate 22 is disposed on its underside and slidably connected to the upper harvesting plate 20, the lower harvesting plate 22 is provided at its front end with a second U-shaped groove 23 corresponding to the first U-shaped groove 21, and the first return spring 25 is disposed at the sliding connection between the upper harvesting plate 20 and the lower harvesting plate 23, when the upper harvesting plate 20 is not subjected to external force, the first return spring 25 always keeps the second U-shaped groove 23 of the lower harvesting plate 22 in a position overlapping with the first U-shaped groove 21 of the upper harvesting plate 20. When the upper surface of the lower harvesting plate 22 exceeds the rear end of the upper harvesting plate 20, the electric slide block 24 is slidably connected thereto, and the electric slide block 24 corresponds to the camshaft 17.

[0031] During operation, by controlling the driving wheel 2 corresponding to the first motor 3, the rack is moved along the entire length until the first U-shaped groove and the second U-shaped groove are caught at the root of the vegetable, and the vegetable is harvested. When the vegetable needs to be uprooted and directly harvested, the electric slide block 24 is slid forward to the lower part of the camshaft 17, and then the third motor 18 is controlled to rotate the camshaft 17, which swings the upper harvesting plate 20 upward via the electric slide block 24 and the lower harvesting plate 22, thereby uprooting the vegetable through the first U-shaped groove 21 and the second U-shaped groove 23. When the vegetable needs to be harvested by a method of picking the leaves while leaving the roots, the lower harvesting plate 22 is slid left and right, and the vegetables can be cut by the shear force generated when the first U-shaped groove 21 and the second U-shaped groove 23 are misaligned. This design allows the vegetables to be uprooted and directly harvested when harvesting.

[0032] As shown in Figs. 5 and 7, a curved ring groove 26 is formed on the outer surface of the camshaft 17, and the maximum displacement D of the curved ring groove 26 is not smaller than the width of the openings of the first U-shaped groove 21 and the second U-shaped groove 23. A first groove 27 is formed on the upper surface of the lower harvesting plate 22, and a first through groove 28 is formed in the electric slide block 24 at a position corresponding to the first groove 27. A pick lever 29 is rotatably connected to the first groove 27 at one end of the bottom of the first groove 27, and a fourth electric telescopic lever 30 is rotatably connected to the first groove 27 at the other end of the bottom of the first groove 27. The telescopic end of the fourth electric telescopic lever 30 is a pick lever 29. The pick lever 29 is hinged at a position above the center of the lower harvesting plate 22 and the electric slide block 24. During operation, the fourth electric telescopic lever 30 is extended, and the extension of the fourth electric telescopic lever 30 causes the pick lever 29 to swing upward. When the pick lever 29 swings upward, the third motor 18 controls the camshaft 17 to rotate, and the upper end of the pick lever 29 enters the curved ring groove 26 on the outer surface of the corresponding camshaft 17. When the camshaft 17 rotates, the pick lever 29 swings back and forth left and right through the curved ring groove 26, thereby realizing the left and right sliding of the lower harvesting plate 22 and the electric slide block 24.

[0033] As shown in FIG. 6, a second groove 31 is opened on the surface of the horizontal shaft 19, and a second through groove 32 is opened at the rear end of the upper harvesting plate 20 and at the position where the front end of the electric slide block 24 corresponds to the second groove 31. A position limiting plate 33 slidably connected to the second groove 31 is disposed in the second groove 31, and a second return spring 34 is disposed between the inner end of the position limiting plate 33 and the inner bottom of the second groove 31. When no external force is applied, the second return spring 34 slides the position limiting plate 33 out of the second groove 31 to the inside of the second through groove 32, The rotation of the upper harvesting plate 20 is restricted, and a push plate 35 is disposed in the second through-groove 32 and corresponding to the position limiting plate 33, and the push plate 35 and the second through-groove 32 are slidably connected. During operation, the motorized slide block 24 slides forward until it is located under the camshaft 17, and the tip of the motorized slide block 24 pushes the push plate 35 and the position limiting plate 33 against the spring force of the second return spring 34, and pushes the position limiting plate 33 into the second through-groove 32 to release the rotation restriction of the upper harvesting plate 20. This design can prevent the upper harvesting plate 20 and the lower harvesting plate 22 from rotating unexpectedly during operation, and ensure the stability of the upper harvesting plate 20 and the lower harvesting plate during the harvesting process.

[0034] As described above, when the present invention is used to harvest vegetables, the drive wheel 2 corresponding to the first motor 3 is first controlled to drive the entire rack 1 to the vegetable growing area, the distance meter 12 is opened, and the height of the vegetables can be measured by the distance meter 12. When the height of the vegetables does not reach the harvesting standard, the first electric telescopic lever 9 is shortened to swing the side plate 8 upward around the rack 1, thereby lifting the harvesting assembly upward, and the harvesting assembly is lifted upward and continues to move forward, passing over the top of the vegetables whose height does not reach the harvesting standard. When the height of the vegetables reaches the harvesting standard, the first electric telescopic lever 9 is extended to swing the side plate 8 downward around the rack 1, so that the first U-shaped groove 21 and the second U-shaped groove 23 are caught at the root position of the vegetables, and the vegetables that reach the harvesting standard are harvested in an appropriate manner through the harvesting assembly. This design realizes the purpose of intelligently determining the growth momentum of the vegetables and selectively harvesting them, which increases the intelligence of the present invention, ensures the maximization of the benefits of vegetable cultivation, and reduces the physical labor intensity of the workers during the harvesting work.

[0035] When harvesting vegetables according to the present invention, different harvesting methods can be adopted according to the type of vegetable. When the vegetables need to be uprooted and harvested directly, the electric slide block 24 is slid forward to the bottom of the camshaft 17, and then the third motor 18 is controlled to rotate the camshaft 17, and the camshaft 17 swings the upper harvesting plate 20 upward via the electric slide block 24 and the lower harvesting plate 22, thereby uprooting the vegetables through the first U-shaped groove 21 and the second U-shaped groove 23. When it is necessary to harvest vegetables by picking the leaves while leaving the roots, the electric slide block 30 is slid backward to a position below the camshaft 17, and the fourth electric telescopic lever 30 is extended. The extension of the fourth electric telescopic lever 30 causes the pick lever 29 to swing upward. When the pick lever 29 swings upward, the third motor 18 controls the camshaft 17 to rotate. The upper end of the pick lever 29 enters the corresponding curved ring groove 26 on the outer surface of the camshaft 17, and when the camshaft 17 rotates, the pick lever 29 is pulled through the curved ring groove 26. This causes the pick lever 29 to swing back and forth from side to side, thereby enabling the lower harvesting plate 22 and the electric slide block 24 to slide left and right. When the lower harvesting plate 22 slides left and right, the first U-shaped groove 21 and the second U-shaped groove 23 slide out of alignment, and when the first U-shaped groove 21 and the second U-shaped groove 23 slide out of alignment, the generated shear force cuts the vegetables. With this design, when harvesting vegetables, the vegetables can be uprooted and harvested directly, or the vegetables can be harvested by leaving the roots and picking the leaves, thereby increasing the applicability of the present invention.

[0036] When harvesting vegetables according to the present invention, if the roots of the vegetables need to be removed after they have been uprooted, the electric slide block 24 can be slid forward to the bottom of the camshaft 17, the extension of the fourth electric telescopic lever 30 can be controlled, and the third motor 18 can be controlled to rotate the camshaft 17 so that the upper end of the pick lever 29 enters the outer curved ring groove 26 of the camshaft 17 corresponding to the top end of the pick lever 29, and the roots of the vegetables can be directly cut off after the roots have been pulled out. This design further increases the functionality of the present invention during use.

[0037] According to the present invention, after the vegetable harvesting operation is completed, the third electric telescopic lever 15 is controlled to extend and the second electric telescopic lever 10 is controlled to contract, so as to move the partition plate 16 backward, so that the harvested vegetables can be better transported to the transporting device 6 in accordance with the harvesting assembly when the partition plate 16 is moved backward, and the second motor 62 is controlled to drive the conveyor belt 61, so that the conveyor belt 61 transports the harvested vegetables into the inside of the collection box, and the convenience during the use of the present invention is further ensured.

[0038] In view of the above, the present invention can selectively harvest vegetables based on the growth vigor of the vegetables, and different harvesting methods can be adopted according to different types of vegetables, with stable usage performance and relatively good versatility. When using the present invention to harvest vegetables, the economic benefit of the vegetables can be ensured and the physical labor intensity during harvesting can be reduced, with relatively good practical value and prospects for popularization.

[0039] The above-described embodiments of the present invention do not limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of protection of the claims of the present invention.
