Description

The present invention relates to the field of agricultural machinery, and more specifically to an intelligent vegetable harvesting agricultural device.

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, whereas 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.

At present, most of the domestic vegetable harvesting is completed artificially, the artificial harvesting efficiency is low, the labor intensity is large, and 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.

However, it cannot intelligently determine the growth vigor of vegetables during harvesting and selectively harvest them, and can only harvest by controlling a disc cutter to rotary cut the roots of the vegetable plants, and cannot uproot them and directly harvest them.

Therefore, how to intelligently determine the growth vigor of vegetables, selectively harvest them, and uproot them to achieve direct harvesting is currently a problem that must be solved by those skilled in the art.

Furthermore, a curved ring groove is opened on the outer surface of the camshaft, and the maximum displacement D of the curved ring groove is not smaller than the width of the groove opening of the first U-shaped groove and the second U-shaped groove. A first groove is opened on the upper surface of the lower harvesting plate, and a first through groove is opened in the electric slide block at a position corresponding to the first groove.

First, when harvesting vegetables according to the present invention, the entire rack can be moved by controlling the driving wheel corresponding to the first motor, 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. After lifting the harvesting assembly upward, the vehicle continues to move forward, passing over the top of the vegetables whose height has not reached 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 have reached 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, increasing the intelligence of the present invention, ensuring the maximization of the benefits of vegetable cultivation, and reducing the physical labor intensity of the operator during the harvesting work.

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 via the electric slide block and the lower harvesting plate, thereby uprooting the vegetables via 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 swings 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 when the camshaft rotates, the pick lever is swung back and forth left and right through the curved ring groove, thereby enabling the lower harvesting plate and the electric slide block to slide left and right.

With this design, the purpose of intelligently determining the growth momentum of the vegetables and selectively harvesting them can be realized.

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 attached to the outer surface of the side plate 8 and at a position corresponding to the camshaft 17, a horizontal shaft 19 fixedly connected to the side plate 8 is disposed on the inner surface of the two side plates 8 and near the lower end thereof, an upper harvesting plate 20 rotatably connected to the horizontal shaft 19 is disposed on the outer surface of the horizontal shaft 19, and a torsion spring is disposed at the rotational connection between the upper harvesting plate 20 and the horizontal shaft 19, and the torsion spring is disposed in the upper harvesting plate 20 can maintain a fixed angle with the horizontal axis 19 when not subjected to external force, a plurality of equally spaced first U-shaped grooves 21 are opened at the tip of the upper harvesting plate 20, a lower harvesting plate 22 is arranged on the underside of the upper harvesting plate 20 and slidably connected to the upper harvesting plate 20, a second U-shaped groove 23 is opened at the tip of the lower harvesting plate 22 and at a position corresponding to the first U-shaped groove 21, a first return spring 25 is arranged at the sliding connection between the upper harvesting plate 20 and the lower harvesting plate 23, when 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 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, an electric slide block 24 is slidably connected, and the electric slide block 24 corresponds to the camshaft 17.

During operation, the drive wheel 2 corresponding to the first motor 3 is controlled to move the entire rack to a position where 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 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, 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 can be slid left and right to cut the vegetable by the shear force generated when the first U-shaped groove 21 and the second U-shaped groove 23 are misaligned. With this design, when harvesting the vegetable, the vegetable can be uprooted and harvested directly.

As shown in Figures 5 and 7, a curved ring groove 26 is opened 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 groove openings of the first U-shaped groove 21 and the second U-shaped groove 23. A first groove 27 is opened on the upper surface of the lower harvesting plate 22, and a first through groove 28 is opened in the electric slide block 24 at a position corresponding to the first groove 27. A pick lever 29 rotatably connected to the first groove 27 is disposed at one end of the bottom of the first groove 27, and a fourth electric telescopic lever 30 rotatably connected to the first groove 27 is disposed 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 fourth electric telescopic lever 30 is hinged at a position above the center of the pick lever 29, and 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.

As shown in FIG. 6, a second groove 31 is formed on the surface of the horizontal shaft 19, and a second through groove 32 is formed at the rear end of the upper harvesting plate 20 where the tip 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 within the second groove 31. 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. The push plate 35 and the second through groove 32 are slidably connected. During operation, the electric slide block 24 slides forward until it is located below the camshaft 17, and the tip of the electric 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.

As described above, when harvesting vegetables according to the present invention, first, the driving wheel 2 corresponding to the first motor 3 is controlled to drive the entire rack 1 to the vegetable cultivation site, 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. After lifting the harvesting assembly upward, the vehicle continues to move forward, passing over the top of the vegetables whose height has not reached 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 have reached 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, increasing the intelligence of the present invention, ensuring the maximization of the benefits of vegetable cultivation, and reducing the physical labor intensity of the operator during the harvesting work.

When harvesting vegetables according to the present invention, different harvesting methods can be adopted depending on 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, which swings the upper harvesting plate 20 upward via the electric slide block 24 and the lower harvesting plate 22, thereby uprooting the vegetables via 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 is controlled to rotate the camshaft 17. The upper end of the pick lever 29 enters the corresponding curved ring groove 26 on the outer surface of the camshaft 17. When the camshaft 17 rotates, the pick lever 29 is rotated 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 shear force generated 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, increasing the applicability of the present invention.

When harvesting vegetables using this invention, if the roots of the vegetables need to be removed after they have been uprooted, the electric slide block 24 is slid forward to the bottom of the camshaft 17, the extension of the fourth electric telescopic lever 30 is controlled, and the third motor 18 is 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 upper 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.

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

In conclusion, the present invention allows selective harvesting based on the growth vigor of vegetables, and different harvesting methods can be adopted for different types of vegetables. It has stable usability and relatively good versatility. When using the present invention to harvest vegetables, it is possible to ensure the economic benefits of the vegetables and reduce the physical labor intensity during harvesting, and it has relatively good practical value and prospects for widespread use.

The above-described embodiments of the present invention do not limit the scope of protection of the present invention.
