Description

Technical Field

[0001] The invention relates to the technical field of environmental equipment, in particular to an automatic loading desert grass grid paving device. Background Art

[0002] Desertification is a major environmental problem and natural disaster currently threatening human survival. It affects 35% of the land area. Researchers worldwide are studying desertification control. How to prevent the spread and intensification of desertification while protecting the desert ecosystem is an urgent challenge.

[0003] Severe desertification not only leads to increasingly infertile land and loss of biodiversity, but also has significant socioeconomic impacts. Consequently, increasing attention is being paid to desertification control. Laying sand barriers is currently one of the most effective methods for sand fixation.

[0004] The grid size of straw grids varies depending on regional wind conditions and microtopography. Grid sizes range from 1.5m x 1.5m to 1m x 1m. Currently, most sandy areas still rely on the most primitive manual laying method. Specifically, wheat straw is pressed into the sand from the center with a shovel to a depth of 20-25cm, leaving 10-15cm exposed above the sand surface. To ensure the grid's effective windbreak and sand fixation, agronomic requirements dictate that the exposed straw portion of the grid stand upright. However, manual laying is labor-intensive, resulting in low quality and efficiency. Existing large-scale laying equipment is also complex and expensive to operate.

[0023] The present invention comprises the following parts: an efficient laying system, a mechanical design adapted to desert environments, a grass grid preparation and supply system, a power system and a mobile platform.

[0024] 1. Efficient laying system: including slotting plow assembly, cam hammer assembly and feeding and laying grass assembly, which realizes rapid laying of grass grids through belt conveyor.

[0025] ① Cam hammer assembly: Utilizing the cam hammer mechanism, the rotation of the cam is used to realize the reciprocating lifting and lowering action of the wedge hammer, hammering the straw mat laid on the sand surface to the specified depth.

[0026] ② Slotting plow assembly: Two agricultural plows are installed in front of the grass grid paving device to perform slotting. The original moldboard plow is changed to a flat-head plow. The improved slotting plow can fully open the slot and loosen the compacted sand. A flange-type plow bracket fixing assembly is installed on the work vehicle body.

[0027] ③ Feeding and laying straw assembly: The straw mat is laid on the sand surface by rotating two pairs of toothed rubber feeding cylinders.

[0028] 2. Mechanical design adapted to the desert: Dust-proof and corrosion-resistant materials are used to ensure the normal operation of the machine in the desert environment; a sand-proof cover and hourglass-shaped body structure are designed to reduce the impact of wind and sand on the machine.

[0029] 3. Grass grid preparation and supply system: including grass weaving assembly, feeding assembly and stepping grass pushing assembly, which stores and automatically transports the grass grids to ensure that the grass grids are in good condition before laying.

[0030] ① Straw weaving assembly: Using the working principle of the sewing machine, the straw delivered by the claw belt is weaved and shaped during the operation of the machine, so as to save raw materials, improve laying efficiency and reduce costs.

[0031] ② Feeding assembly: The processed straw mats are transported to the storage bin device for folding storage. A straw blocking assembly is installed at the front to prevent excessive straw discharge at one time during operation. A decompression spring is installed between the two straw blocking shafts to ensure that only one layer of straw is delivered each time, thereby achieving the functions of fixing, storing, and controlling smooth discharge.

[0032] ③ Stepping grass pushing assembly: uses ball screw and ball nut as transmission part, connected with the grass pushing plate. When rotating, it drives the grass pushing plate forward. The use of ball screw and ball nut can slow down the feeding speed, allowing the grass to be slowly pushed into the grass conveying assembly.

[0033] 4. Power system and mobile platform: Electric motors are used to provide power for each assembly to ensure that the grass grid paving device can move freely in the desert environment, and a crawler chassis is used.

A battery pack is used as the power source, and a drive motor provides power for each part. A belt drive is used to transmit the power output by the motor to the straw weaving assembly and the feeding and laying assembly, realizing the straw weaving and automatic laying functions, reducing the intensity of manual laying. The power is transmitted to the cam, driving the wedge hammer to press the straw into the sand.

[0035] ② Mobile platform: Powered by a crawler tractor, the I-shaped cylinder connected to the crawler tracks bears the weight of the entire vehicle. The crawler tracks increase the contact area, reduce the pressure on the ground, improve the protection performance, adapt to different terrains, keep the vehicle body stable and improve the vehicle's traction. The crawler tracks have a low ground contact pressure, large traction, good carrying capacity, and a large force area, which reduces the pressure per unit area. When driving in the desert, it is not easy to get stuck in it, and can support the normal operation of the paving device in the desert. It also eliminates the useless work loss caused by wheel slippage, has strong power, saves energy and reduces consumption, and reduces working costs. The tractor and the work vehicle are connected by an articulated mechanism, which makes the paving device easy to turn and simple to operate when operating in the desert.

The drive motor is installed between the two cam hammer supports 1303, and the second bearing 1304 is installed in the middle hole of the cam hammer support 1303, and is used to support the transmission shaft of the drive motor. A cam is provided on the output shaft of the drive motor to provide power for the wedge hammer 1301 to move up and down. The irregular rotation of the cam drives the pull rod 1305 to move up and down, and the up and down movement of the pull rod 1305 drives the connecting rod 1302 to move up and down, thereby driving the wedge hammer 1301 to move up and down, and then hammering the grass into the sand and continuously compacting it. The depth of pressing into the sand is not less than 30 cm, which avoids the situation of loose grass compaction and extends the service life of the grass grid.

[0073] The forage conveying assembly 8 includes two transmission shafts, eight transmission wheels and eight hook belts 801. The transmission wheels are fixedly connected to the transmission shafts in parallel through keys. The hook belts 801 are sleeved on the transmission wheels. The transmission shaft is connected to the reserved holes of the supporting body 3 through bearings. The upper transmission shaft is the active transmission shaft, and the transmission wheel on the active transmission shaft is the active transmission wheel. A worm is provided between the two transmission wheels of the lower transmission shaft. The middle part of the active transmission wheel is connected to a pulley by a key. The forage conveying assembly 8 and the cam hammer assembly 13 share the same drive motor. The pulley on the active transmission wheel is connected to the pulley on the output shaft of the drive motor as power, realizing the automatic feeding function and reducing labor; the hook on the hook belt 801 is L-shaped, which is convenient for hooking out the forage in the forage storage bin 9 with the hook and transmitting it to the forage weaving assembly 7, realizing the automatic feeding function.

[0074] There are two grass storage bins 9, including trapezoidal boxes, which are installed in parallel on the load-bearing body 3 and can load a variety of different types of grass. The capacity of the two trapezoidal boxes is enough to lay grass grids for one acre of land at a time.

[0075] The step-by-step grass pushing assembly 14 is provided with two and is installed in parallel at the lower end of the grass storage bin 9, including a second rectangular groove, a ball screw pair and a grass pushing plate. The grass pushing plate is welded to the ball nut of the ball screw pair and is located in the grass storage bin 9. The ball screw pair is installed in the second rectangular groove. The front end of the ball screw of the ball screw pair is provided with a turbine structure. The turbine structure is connected to the worm gear arranged below the grass conveying assembly 8 to obtain power, and then the power is obtained through the multi-stage transmission deceleration in front to achieve the effect of slowly pushing grass. It is then connected to the grass storage bin 9 through a screw. The ball screw pair drives the grass pushing plate to move linearly through rotation. The grass pushing plate slowly pushes the grass to the front end, which is convenient for the hook claw of the grass conveying assembly 8 to hook up the grass, so that the grass in the grass storage bin 9 can be completely used up at one time, thereby increasing the laying area of ​​one bin of grass. The use of ball screws and ball nuts can slow down the feeding speed, allowing the grass to be slowly pushed into the grass conveying assembly 8.

[0076] The working process of this embodiment is:

[0077] The operator fills the grass storage bin 9 with grass and turns on the control switch of the work vehicle 2. The grass is then pushed out of the weeding bin 9 through the step-by-step grass pushing assembly 14, so that the hook of the grass conveying assembly 8 hooks the grass and conveys it to the end of the feeding assembly 6. After the grass is woven by the grass weaving assembly 7, it is sent out from the front end of the feeding assembly 6 to the feeding and laying assembly 4. During the first laying in this step, the operator needs to manually feed the grass between the two axes of the feeding and laying assembly 4. When the grass is laid in the working area, the operator first adjusts the slotting depth of the slotting plow assembly 11 according to the terrain.
