[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The purpose of the present invention is to provide a digging and seedling-dropping device for planting in sandy land, which can realize that after the planting pit is dug, the seedling-dropping port of the seedling-dropping device can be quickly aligned and positioned with the planting pit, and the positioning is accurate without manual assistance, so as to solve the problem that the seedling-dropping device in the prior art takes a long time to locate the planting pit and the positioning is inaccurate, which can reduce the planting cost and improve the planting efficiency and the survival rate of the seedlings.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] like Figure 1 to Figure 3 As shown, this embodiment proposes a digging and seedling throwing device 100 for planting in sand, including a carrying mechanism 1, a supporting mechanism 2, a displacement mechanism 3, a planting pit digging device 4 and a seedling throwing device 5, wherein the carrying mechanism 1 is preferably a frame, which can be connected to a walking device, and the walking device includes but is not limited to a tractor, etc.; the carrying mechanism 1 has a planting position, which is used to align with the planting position 6 when in use. It should be noted that the planting position may not be a specific structure, but a reference position, such as Figure 2 and Figure 3As shown, the vertical dotted line refers to the planting position. In addition to measuring whether the planting pit digging device 4 and the seedling throwing device 5 have moved to the correct position, the planting position also plays a role in positioning the carrying mechanism 1 to ensure that the carrying mechanism 1 is located at the correct position of the planting site when in use. The planting pit digging device 4 and the seedling throwing device 5 are both arranged on the support mechanism 2 and are located above the planting position 6; the support mechanism 2 is arranged on the carrying mechanism 1 through the displacement mechanism 3, and the displacement mechanism 3 can drive the support mechanism 2 to switch between the first state and the second state, wherein, in the first state, the planting pit digging device 4 reaches the planting position and is aligned and positioned with the planting position 6, so as to dig downward at the planting position 6 to form a planting pit, and in the second state, the seedling throwing device 5 reaches the planting position, and the seedling dropping port of the seedling throwing device 5 is aligned and positioned with the planting pit, so as to drop the seedlings into the excavated planting pit through the seedling throwing device 5. The above-mentioned digging and seedling-planting device 100 for planting in sand can move in a straight line along the walking direction of the walking device under the driving action of the walking device, and cyclically dig holes and plant seedlings on the straight line, so as to complete the seedling planting in a row. In this planting process, the planting pit digging device 4 and the seedling-planting device 5 are driven by the displacement mechanism 3 to alternately reach the planting position to align and position with the planting position 6 up and down, so as to achieve accurate pit digging and precise seedling planting in each pit digging and seedling-planting process. The displacement mechanism 3 adopts a mechanical structure, which has the advantages of precise movement and controllable stroke. It does not require manual assistance. After each planting pit digging device 4 digs a planting pit, the seedling-planting device 5 can be moved to the seedling drop mouth and aligned with the planting pit. The positioning is accurate, which improves the planting efficiency while reducing the cost of manual planting and improving the accuracy and survival rate of seedling placement.

[0041] In some embodiments, the displacement mechanism 3 includes a driving source, a slide rail 31, and a slider 32 slidably assembled with the slide rail 31, one of the slide rail 31 and the slider 32 is connected to the carrying mechanism 1, and the other is connected to the supporting mechanism 2; the driving source is used to drive at least one of the slide rail 31 and the slider 32 to move the supporting mechanism 2 relative to the carrying mechanism 1, thereby realizing the conversion of the supporting mechanism 2 between the first state and the second state.

[0042] In some embodiments, the slide rail 31 is a linear slide rail, and accordingly, the driving source is preferably a linear driving source. The linear driving source includes but is not limited to two driving forms of a hydraulic cylinder and a pneumatic cylinder. During installation, the hydraulic cylinder or the pneumatic cylinder can be connected between the linear slide rail and the slider 32, or can be connected to the carrying mechanism 1 and one of the slide rail 31 and the slider 32 connected to the supporting mechanism 2 to ensure that the slide rail 31 and the slider 32 can move relative to each other.

[0043] Taking the linear slide rail disposed on the mounting mechanism 1 and the slider 32 disposed on the support mechanism 2 as an example, the linear drive source may be a hydraulic cylinder or a pneumatic cylinder, which is disposed on the mounting mechanism 1, and the piston rod end of the hydraulic cylinder or the pneumatic cylinder is connected to the slider 32. The hydraulic cylinder or the pneumatic cylinder is extended and retracted to drive the slider 32 to reciprocate along the slide rail 31, thereby realizing the conversion of the support mechanism 2 between the first state and the second state.

[0044] In some embodiments, the linear slide rail may be a protruding slide rail disposed on the outside of the mounting mechanism 1 , or may be a grooved slide rail provided on the mounting mechanism 1 .

[0045] In some embodiments, the support mechanism 2 is a plate-type mounting member. In practical applications, for example Figure 1 to Figure 3 As shown, the supporting mechanism 2 can be installed on the front side of the carrying mechanism 1 through the aforementioned linear slide rail and slider 32 assembly, and the planting pit digging device 4 and the seedling throwing device 5 are arranged side by side on the supporting mechanism 2. At this time, the planting pit digging device 4 and the seedling throwing device 5 are both located on the front side of the carrying mechanism 1, and the seedling dropping openings of the planting pit digging device 4 and the seedling throwing device 5 are both vertically facing downward; the rear side of the carrying mechanism 1 is opposite to the front side, and the rear side of the carrying mechanism 1 is generally used to be connected to a walking device, and the rear side of the carrying mechanism 1 is provided with a hook that can be connected to the walking device.

[0046] In some embodiments, the planting pit digging device 4 and the seedling throwing device 5 can be conventional technologies that are mature in the field. For example, the planting pit digging device 4 is an auger excavator, and the seedling throwing device 5 is a seedling transport and throwing device. The specific structure and working principle of the planting pit digging device 4 and the seedling throwing device 5 are not described in detail here. In actual applications, the planting pit digging device 4 and the seedling throwing device 5 are respectively fixedly installed with the support mechanism 2 through their respective device housings using components such as screws. The displacement mechanism 3 is used to adjust the position of the planting pit digging device 4 and the seedling throwing device 5, but it does not affect the structural functions of the planting pit digging device 4 and the seedling throwing device 5 themselves.

[0047] When the digging and seedling throwing device 100 for planting in sandy land reaches the planting position 6 to be operated, as shown in FIG. Figure 2 As shown, the planting pit digging device 4 is located at the planting position, and the auger axis of the planting pit digging device 4 is aligned with the planting position 6. At this time, the planting pit can be dug downward under the action of the lifting device and the power mechanism; when the planting pit digging device 4 completes the operation and returns to the initial position, the displacement mechanism 3 drives the planting pit digging device 4 away from the planting position through the action of the slide rail 31 and the slider 32, and drives the seedling throwing device 5 to the planting position at the same time. Figure 3As shown, the seedling drop opening of the seedling throwing device 5 is aligned with the planting pit, and then the seedling throwing device 5 throws the seedlings in the silo into the planting pit; finally, the displacement mechanism 3 drives the seedling throwing device 7 away from the planting position in the opposite direction, and the planting pit digging device 4 returns to the planting position again, completing a planting operation. Each time the carrying mechanism 1 moves to a certain position, the digging and seedling throwing device 100 for sandy land planting performs the above-mentioned digging, seedling throwing and planting once, until all the planting operations are completed.

[0048] It should be noted that the moving distance of the above-mentioned planting pit digging device 4 and the seedling throwing device 5 is mainly achieved by controlling the stroke of the hydraulic cylinder or the air cylinder, which has the advantage of high control accuracy.

[0049] To sum up, the digging and seedling throwing device 100 for sandy land planting proposed in this scheme has a novel and reasonable structure. Through the design of the displacement mechanism 3, the planting pit digging device 4 and the seedling throwing device 5 can alternately reach the planting position to align and position with the planting position 6 up and down. The displacement mechanism 3 is driven by a hydraulic cylinder or an air cylinder, and has the advantages of precise movement and controllable stroke. It does not require manual assistance. After each planting pit digging device 4 digs a planting pit, the seedling throwing device 5 can be driven to the seedling drop mouth and aligned with the planting pit. The positioning is precise, which improves the planting efficiency and can reduce the cost of manual planting. It improves the accuracy and survival rate of seedling placement, solves the problems of inaccurate positioning of existing desert planting pits and low planting efficiency, and at the same time solves the existing technical difficulties and reduces the planting cost.

[0050] Example 2

[0051] This embodiment proposes a digging and seedling throwing device 100 for planting in sandy land, which is different from the embodiment 1 in that the linear drive source of this embodiment adopts a screw slide assembly. Taking the linear slide rail arranged on the carrying mechanism 1 and the slider 32 arranged on the supporting mechanism 2 as an example, the screw slide assembly includes a motor and a screw rod, and the two ends of the screw rod are supported and installed on the carrying mechanism 1 through the bearing seat, and the screw rod is parallel to the linear slide rail, and the screw rod passes through the slider 32 and is threaded with the slider 32; the two ends of the screw rod are respectively rotatably connected to the bearing seat through the bearing; the motor is arranged on the carrying mechanism 1, and the output end of the motor is connected to the end of the screw rod. At this point, the screw slide assembly and the linear slide rail and the slider 32 together constitute an electric slide assembly. In specific applications, the screw rod can be located on the upper side of the linear slide rail, or it can be located on the side of the linear slide rail. The motor drives the screw rod to rotate in situ, which can drive the slider 32 to move along the linear slide rail, thereby realizing the conversion of the supporting mechanism 2 between the first state and the second state.

[0052] The electric slide assembly has a good self-locking function and high moving accuracy. It can accurately control the moving position of the planting pit digging device 4 and the seedling planting device 5, which can improve the planting efficiency while reducing the cost of manual planting, improve the accuracy and survival rate of seedling placement, and improve the operating reliability and stability of the device.

[0053] Example 3

[0054] This embodiment provides a digging and seedling throwing device 100 for planting in sandy land, which is different from the first and second embodiments in that the displacement mechanism 3 as a whole adopts a multi-degree-of-freedom mechanical arm. Compared with the aforementioned slide rail and slider assembly, the multi-degree-of-freedom mechanical arm has the characteristics of variable motion trajectory but high motion accuracy, and can realize multi-position transformation of the planting pit digging device 4 and the seedling throwing device 5.

[0055] The above-mentioned multi-degree-of-freedom robotic arm can specifically be a four-degree-of-freedom robotic arm, a six-degree-of-freedom robotic arm, etc., all of which are conventional finished products, and the specific structure and working principle will not be repeated here.
