Description

Technical Field

[0001] This invention relates to a sand barrier planting machine, specifically a self-propelled tracked sand barrier planting machine, belonging to the field of sand barrier planting technology. Background Technology

[0002] my country has a vast area of ​​desertified land, making windbreak and sand-fixing projects a challenging task. Among these, laying shrub and willow sand barriers is one of the key technologies for controlling shifting sands. However, current sand barrier planting operations still heavily rely on manual labor, resulting in prominent problems such as high labor intensity, low work efficiency, and inconsistent planting quality.

[0003] Although some sand planting machinery has appeared on the market, such as the fully automatic integrated intelligent sand planting machine disclosed in the authorization announcement number CN220326427U, which uses water flow erosion to form planting pits in the sand to avoid the loss of sand moisture, this method is mainly suitable for planting seedlings with roots. For branch-type sand barriers that require direct planting, its clamping and fixing mechanism is difficult to effectively grasp irregularly shaped shrub branches, and branches are prone to slipping or shifting during transportation, resulting in insufficient planting verticality. Another example is the process-oriented multi-threaded seedling planting equipment for desertified land disclosed in the publication number CN119837006A. Although it achieves multi-threaded operation through automated rotating seed hopper and pneumatic seedling planting device and integrates irrigation function, the walking mechanism of its tracked mobile trolley has a fixed grounding shape. When facing the soft, sloping and pitted terrain common in sandy land, the tracks are prone to sinking or slipping, resulting in poor passability and difficulty in ensuring continuous and stable operation. Furthermore, the seedling bin design of this equipment is geared towards standardized seedlings, lacking an effective separation and directional supply mechanism for branches of varying lengths and shapes in sand barriers. This leads to entanglement during material handling, requiring frequent manual intervention and failing to meet the automated material supply requirements of large-scale sand barrier projects. In existing technologies, the power systems of sand barrier planting machines mostly rely on a single fuel or grid power supply mode. In desert areas far from the power grid, fuel refueling is difficult and costly, and exhaust emissions do not meet the environmental protection requirements for ecological restoration. Based on this, this application proposes a self-propelled tracked sand barrier planting machine. By optimizing the design of the partition bars and hollow moving plates of the sand barrier storage and retrieval components to stagger the material retrieval, the problems of branch entanglement and single-time material retrieval reliability are solved. The vibration insertion and conical clamping mechanism of the sand barrier planting components improve the consistency and verticality of planting depth. The multi-mode track adjustment wheel of the self-propelled components enhances the equipment's passability and stability on soft, sloping, and uneven sandy land. Combined with a solar hybrid power system, it achieves energy self-sufficiency and low carbon emissions for field operations, thereby comprehensively improving the mechanization level and engineering quality of sand barrier planting.

[0015] The present application has the following beneficial effects: 1. The present invention is provided with a frame assembly, a sand barrier storage and retrieval assembly, a sand barrier planting assembly, a power drive assembly, and a self-propelled assembly. By integrating the sand barrier storage and retrieval assembly, the sand barrier planting assembly, and the power drive assembly on the frame assembly, it is possible to store a large number of branch sand barriers on the sand barrier storage and retrieval assembly, and to transfer the branch sand barriers to the sand barrier planting assembly through the sand barrier storage and retrieval assembly, so that the branch sand barriers can be planted in the sand through the sand barrier planting assembly, thereby realizing the continuous automated operation of the sand barrier planting machine.

[0025] As Figure 1 , Figure 2 , Figures 7 to 10As shown, the fixing clamp plate 31 of the sand barrier planting assembly 3 is fixedly connected with a vibration motor 33, the two side plates of the U-shaped side support plate 15 are fixedly connected with sand barrier planting slide rails 34 arranged in a vertical manner, the slide blocks of the sand barrier planting slide rails 34 are fixedly connected at the ends of the fixing clamp plate 31, the clamping grooves 35 of the movable clamp plate 32 are arranged in one-to-one correspondence with the gaps between the adjacent sand barrier clamping plates 24, and the inner side surfaces of the conical clamps 36 connected with each clamping groove 35 are all provided with friction surfaces 37. When the sand barrier planting assembly 3 clamps the branch sand barrier and inserts it into the sand soil downward, the vibration motor 33 is started to generate high-frequency low-amplitude mechanical vibration, which is transmitted to the branch sand barrier through the fixing clamp plate 31 and the movable clamp plate 32. The vibration energy can greatly reduce the internal friction and cohesion between sand particles, so that the resistance encountered by the sand barrier tip is suddenly reduced. Moreover, the vibration energy can help the sand barrier to overcome the hard inclusions or local dense areas that may exist in the sand soil, and extrude or shake off the hard inclusions or local dense areas through continuous micro-impact, so that the branch sand barrier can be inserted into the preset depth more labor-savingly and quickly. The vertical sand barrier planting slide rails 34 fixedly connected with the two sides of the U-shaped side support plate 15 provide accurate vertical guidance for the sand barrier planting assembly 3, so as to ensure that the whole planting assembly can only move in the vertical direction, avoiding the possible lateral swing or inclination in the planting process. The gaps between the clamping grooves 35 on the movable clamp plate 32 and the adjacent sand barrier clamping plates 24 are arranged in one-to-one correspondence, so as to ensure that the branch sand barrier handed over from the sand barrier storage and taking assembly 2 can be accurately received and positioned by the clamping grooves 35 and the conical clamps 36 of the sand barrier planting assembly 3, avoiding the sand barrier from falling or the position deviating in the handover process. It should be noted that the vibration motor 33 is of YZU-10-4 type, the exciting force reaches 10kN, the frequency adjustable range is 30-50Hz, and the generated mechanical vibration is transmitted to the branch through the fixing clamp plate 31 to form an axial exciting force. This high-frequency micro-amplitude vibration can make the sand particles produce a liquefaction effect, reduce the internal friction angle of the sand soil from 35° to 12°, and reduce the insertion and extraction resistance by more than 60%. The sand barrier planting slide rails 34 are also preferably HGW series hydraulic cylinder guide rails, and the four sand barrier planting slide rails 34 are driven by a common hydraulic pump station 111 as a power source. The oil circuit first divides the oil into two paths through a TFA type synchronization valve, and then divides the two paths again through the TFA type synchronization valve to drive the four slide rails on the left and right sides to be driven synchronously.

[0026] Further, a clamping plate setting groove 312 is formed in the fixed clamping plate 31, the movable clamping plate 32 is movably inserted into the clamping plate setting groove 312, a plurality of limiting rods 38 are fixedly connected in the groove of the clamping plate setting groove 312, a limiting groove 39 is formed in one side plate body of the movable clamping plate 32 located in the clamping plate setting groove 312, the rod body of the limiting rod 38 is movably inserted into the limiting groove 39, a stop block 310 is fixedly connected to one end of the limiting rod 38 located in the limiting groove 39, a return spring 311 is sleeved on the rod body of the limiting rod 38 located in the limiting groove 39, and the return spring 311 is abutted between the front end groove wall of the limiting groove 39 and the stop block 310. The clamping plate setting groove 312 formed in the fixed clamping plate 31 provides a constrained sliding space for the movable clamping plate 32, guiding the movable clamping plate 32 to only perform linear reciprocating motion relative to the fixed clamping plate 31. The cooperation of the limiting rod 38 and the limiting groove 39 limits the sliding stroke of the movable clamping plate 32, so that the movable clamping plate 32 can freely slide within a certain range and will not fall out of the clamping plate setting groove 312. When the movable clamping plate 32 is closed to the fixed clamping plate 31 to clamp the sand barrier, the return spring 311 is compressed. When the planting action is completed and the sand barrier needs to be released, the external driving force is removed. At this time, the return spring 311 releases the elastic potential energy stored therein, pushes the movable clamping plate 32 to quickly and automatically reset to the initial open position along the limiting groove 39, and prepares for receiving the next batch of sand barriers, ensuring the rapid and coherent planting rhythm. No additional power source is needed to drive the opening action. The return spring 311 also plays a buffering role. At the moment when the sand barrier is inserted into the sand, it may encounter hard foreign objects and generate an impact. At this time, the elastic deformation of the return spring 311 can absorb part of the impact energy, avoiding damage to the clamping plate caused by rigid collision.
