Description

Technical Field

[0001] The invention relates to the technical field of seabuckthorn harvesting, and in particular to a seabuckthorn harvesting device capable of simultaneously and efficiently harvesting double rows of seabuckthorn. Background Art

[0002] Seabuckthorn fruit is a nutritious economic crop with certain medicinal value. Fresh seabuckthorn fruit needs to be harvested within one and a half months, otherwise the quality of the seabuckthorn fruit will be seriously affected. With large-scale planting and huge harvest volume today, the demand for more efficient and higher-quality seabuckthorn harvesting equipment is also increasing day by day.

[0003] At present, most of the equipment for sea buckthorn harvesting can only harvest a single row, and it is impossible to use a two-row method for more efficient harvesting. Most of these harvesting equipment use reciprocating cutters installed in fixed positions for cutting, and the position of the cutters cannot be adjusted at any time according to the height of the sea buckthorn tree. In addition, the gathering devices of most harvesters are completely fixed on the frame, and can only gather branches at a specific width. The width and height between the two devices cannot be adjusted according to the growth of the branches. The gathering effect of the branches is poor, which greatly affects the net harvest rate. In addition, due to the large vibration and inertia of most reciprocating cutters, the walking speed of the vehicle body is greatly limited. Although it can completely replace manual picking, there is still a lot of room for development in terms of efficiency and other aspects. Summary of the invention

[0049] The sea buckthorn harvesting device for efficient double-row simultaneous harvesting of sea buckthorn of the present invention adopts the above-mentioned mechanism to adjust the height and the width between the branch gatherers, and comprises the following steps:

[0050] S100: When starting to work, the slewing support bearing 201 is rotated to a suitable position according to the distance between the vehicle body and the left and right rows of sea buckthorn trees, and the hydraulic folding machine 202 is folded 90 degrees to put all components in the working position.

[0051] S200: Before operation, the angle of the branch gatherer 601 and the extension length of the branch wheel sleeve 701 are adjusted according to the distribution of branches. During the operation, the branch gatherer 601 first straightens the fallen branches along the curved slope.

[0052] S300: Adjust the position of the cutter and the branch-moving wheel 702 according to the actual height of the sea buckthorn tree. When the distance between the cutter and the branch-moving wheel 702 is reduced, the extension of the top rod 406 of the top rod sensor 405 will be forced to decrease.

[0053] S400: The branch-moving wheel 702 further combs the straightened branches and tilts the branches toward the conveyor belt 302, while sending the branches into the cutting range of the cutter.

The cutting mechanism 5 uses a parallel four-bar linkage to adjust the height, and the branch-moving wheel 702 directly pushes the branch-moving wheel adjustment rod 407 through a hydraulic cylinder to adjust the height. A push rod sensor 405 is provided between the parallel four-bar linkage and the branch-moving wheel adjustment rod 407, and the distance between the two can be controlled to prevent the branch-moving wheel 702 and the cutting mechanism 5 from interfering due to the small distance, which greatly improves the safety and stability.

[0064] In a further embodiment of the present invention, the fourth embodiment: combining Figure 4 , Figure 5 To illustrate this embodiment, the height adjustment mechanism 4 of this embodiment includes: a rear support plate 401, an upper connecting rod 402, a lower connecting rod 403, a front vertical plate 404, a push rod sensor 405, a push rod 406, a branch-moving wheel adjustment rod 407, a parallel four-bar linkage hydraulic cylinder 408, and a branch-moving wheel hydraulic cylinder 409.

[0065] In this embodiment, the rear support plate 401 is welded to the front end of the fixing frame 301, one end of the upper connecting rod 402 and the lower connecting rod 403 are hinged to the connecting pieces in the middle and lower parts of the rear support plate 401 through a pin shaft, and the other ends of the upper connecting rod 402 and the lower connecting rod 403 are hinged to the positioning holes in the upper and middle parts of the front vertical plate 404 through a pin shaft, forming a parallel four-link mechanism that can swing up and down; the working end of the parallel four-link hydraulic cylinder 408 is connected to the positioning hole in the middle part of the lower connecting rod 403 through a pin shaft connection, and the other end is connected to the connecting part at the lowest end of the rear support plate 401 through a pin shaft; The branch plucking wheel adjusting rod 407 is hinged on the connecting piece at the upper end of the rear support plate 401 by means of a pin connection. The working end of the branch plucking wheel hydraulic cylinder 409 is connected to the connecting part at the lower end of the branch plucking wheel adjusting rod 407 by means of a pin, and the other end is connected to the connecting part at the upper end of the rear support plate 401 by means of a pin. The push rod sensor 405 is fixed to the front end surface of the front vertical plate 404 by means of a bolt connection. A small guide rail 414 is provided on the lower end surface of the branch plucking wheel adjusting rod 407. The connecting part of the push rod 406 is connected to the guide rail 414 by means of a pin, so that the push rod 406 can slide in the guide rail 414.

[0066] The specific movement mode of this embodiment is as follows: the parallel four-bar linkage composed of the rear support plate 401, the upper connecting rod 402, the lower connecting rod 403, and the front vertical plate 404 is an integral whole, the rear support plate 401 is completely fixed and keeps parallel to the front vertical plate 404, the upper connecting rod 402 and the lower connecting rod 403 always keep parallel, under the telescopic movement of the parallel four-bar linkage hydraulic cylinder 408, it will directly drive the lower connecting rod 403 to rotate downward or upward, and the upper connecting rod 402 will also move synchronously, and the front vertical plate 404 directly connected to the two will also be driven to move downward or upward synchronously, and Figure 5 The height can be adjusted within the range of the upper limit position 412 and the lower limit position 413 shown in the figure; the adjusting rod 407 of the branch wheel is hinged with the rear support plate 401, and the arc swing is realized under the direct push of the hydraulic cylinder 409 of the branch wheel. Figure 4 The height can be adjusted within the range of the upper limit position 410 and the lower limit position 411 shown in the figure. The branch shifting wheel 702 has a certain height difference between the upper limit position 410 and the lower limit position 411 of the swing, so as to adjust the height of the branch shifting wheel 702. Since the radius of the branch shifting wheel 702 is too large, it is easy to interfere with the branch gatherer 601 below. Therefore, a certain range of values ​​of the extension amount of the push rod sensor 405 is set as a safe value. When the branch shifting wheel adjustment rod 407 and the parallel four-bar linkage adjust the height respectively, the extension amount of the push rod 406 will definitely change. If the changed value is still within the safe range, it can be freely adjusted. If the distance between the branch gatherer 601 and the branch shifting wheel 702 is reduced too much, resulting in the extension amount of the push rod 406 exceeding the safe value range, the alarm indication module of the push rod sensor 405 will sound an alarm, and the extension amount of the push rod 406 will not decrease any more. The user needs to adjust the height according to the alarm indication. In this way, the two can always be in a dynamic equilibrium state.
