Description

Technical Field

[0001] The utility model relates to a desert sand control and fixation vehicle, belonging to automated desert control equipment. Background Art

[0002] Among the engineering sand fixation methods, laying grass grids has been proven in practice to be the most effective method for sand control. Grass grid sand control is a pioneering effort in the history of world sand control. It is widely used in my country as a preliminary measure for sand fixation and afforestation or as an independent sand fixation measure in heavy sand-damaged areas where plants are difficult to grow.

[0003] In desert areas, my country often uses straw grid planting to control sand. However, the current planting method requires manual laying of straw first, and then manual or mechanical pressing of straw, so that the two ends of the straw are raised and the middle is pressed into the sand, thereby protecting the sand. This operation is time-consuming and labor-intensive, with high labor costs and low work efficiency.

[0004] Patent No. 202122049309.8 discloses an intelligent planting and sand control vehicle based on straw grids. It includes a grooving device, a conveying device, a grass pressing device, a gathering device, and a sowing device. The grooving device first opens a groove in the desert area, and the conveying device pushes the wheat straw into the double rollers, and the rollers crush the wheat straw and uniformly transfer it to the groove below. The grass pressing wheel of the grass pressing device folds the fallen wheat straw in half and presses it into the sand, so that the horizontal wheat straw is vertically inserted into the sand.

[0005] The current technical considerations are not comprehensive and have the following disadvantages: general mechanical grass pressing uses large mechanical vehicles, which rely on the vehicle's own weight to press the grass into the sand. This type of mechanical vehicle consumes a lot of energy and is inconvenient to transport. In order to solve one of the above problems, a desert sand control and fixation vehicle is urgently needed. Utility Model Content

[0006] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: how to achieve the effect of sand control by laying grass grids through mechanized operations, while saving manpower and material resources and improving sand control efficiency, and a desert sand control and fixation vehicle is provided for this purpose.

[0007] The desert sand control and fixation vehicle described in the utility model comprises a box-type body and a cab connected to the box-type body, a crawler walking mechanism is installed at the bottom of the box-type body, and is characterized in that a lifting type grass pressing wheel mechanism is arranged in the inner middle part of the box-type body, the front section of the box-type body is arranged as a power bin, the rear section of the box-type body is arranged with a straw bin, a horizontal feeder is arranged at the bottom of the straw bin for conveying the straw in the straw bin to the lifting type grass pressing wheel mechanism, and a loading bin door is arranged at the rear of the box-type body.

[0008] The straw can be loaded into the straw bin by opening the loading bin door. After the straw is loaded, when driving normally, the lifting type straw pressing wheel mechanism needs to be raised to a high position. The sand control vehicle can be powered by the crawler running mechanism and driven by the driver to the operation area, and then the lifting type straw pressing wheel mechanism is lowered to the low working position. The driver operates the desert sand control and fixation vehicle to drive at a low speed while opening the horizontal feeder to convey the straw in the straw bin to the lifting type straw pressing wheel mechanism. The lifting type straw pressing wheel mechanism receives the conveyed straw and presses the middle part of the straw into the sand. The straw mentioned above is wheat straw and rice straw.

[0009] Preferably, the lifting type straw pressing wheel mechanism includes a lifting bin. A straw pressing disc for pressing the straw into the sand is rotatably installed at the bottom of the lifting bin. The upper part of the straw pressing disc extends into the lifting bin through a horizontal feeding channel at the bottom of the lifting bin. Serrations are provided at the edge of the outer circumference of the straw pressing disc. Lifting oil cylinders for driving the lifting of the lifting bin are respectively arranged on both sides of the lifting bin. A vertical feeder for pressing the straw into the serrations is arranged above the straw pressing disc. A partition for installing the vertical feeder is provided in the middle of the lifting bin. The partition divides the lifting bin into a front chamber and a rear chamber. The rear chamber is communicated with the straw bin. A vertical feeding channel cooperating with the straw pressing disc is provided on the partition.

[0010] The lifting oil cylinder is used to drive the overall lifting of the lifting bin to adjust the height of the straw pressing disc. When the lifting bin is lowered to the low position, the bottom of the straw pressing disc can be inserted into the sand. At the same time, the horizontal feeder is opened to convey the straw in the straw bin to the lifting type straw pressing wheel mechanism. The vertical feeder is opened to press the middle part of the straw into the serrations on the straw pressing disc. The strands of straw rotate with the rotation of the straw pressing disc until the middle part of the corresponding straw is pressed into the sand, completing the sand fixation operation.

[0011] Preferably, the horizontal feeder includes multiple groups of teeth A. The teeth A are driven by a servo cylinder A installed on the box body of the vehicle to move horizontally back and forth, so as to convey the straw in the straw bin to the straw pressing disc; the vertical feeder 9 includes multiple groups of teeth B. The teeth B are driven by a servo cylinder B installed on the partition to move vertically back and forth, so that the straw close to the straw pressing disc is loaded on the serrations and can rotate with the rotation of the straw pressing disc.

[0012] Preferably, through grooves for the teeth B to penetrate are provided on the partition to avoid interference with the lifting of the teeth B.

[0013] Preferably, the crawler running mechanism includes a left crawler and a right crawler arranged at intervals.

[0014] Preferably, a power unit is arranged in the power bin. The power source of the power unit is a diesel engine or a gasoline engine.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] For the desert sand control and fixation vehicle described in the present utility model, the serrated grass pressing disc can drive the rice straw to fold in half and directly press it into the sand layer by 20 cm, meeting the requirements of sand fixation construction. By laying straw checkerboards through mechanized operations, the sand control effect can be achieved, while saving manpower and material resources and improving the sand control efficiency.

[0017] For the desert sand control and fixation vehicle described in the present utility model, its overall structure is simple, easy to manufacture, and has a stable structure, with good prospects for market promotion and use.

[0018] For the desert sand control and fixation vehicle described in the present utility model, the lifting oil cylinder is used to drive the overall lifting of the lifting bin to adjust the height of the grass pressing disc. When the lifting bin is lowered to the low position, the bottom of the grass pressing disc can be inserted into the sand. At the same time, the horizontal feeder is turned on to convey the straw in the straw bin to the lifting type grass pressing wheel mechanism. The vertical feeder is turned on to press the middle part of the straw into the serrations on the grass pressing disc. The strands of straw rotate with the grass pressing disc until the middle part of the corresponding straw is pressed into the sand, completing the sand fixation operation.

[0019] For the desert sand control and fixation vehicle described in the present utility model, the tooth A is driven by the servo cylinder A installed at the bottom of the box-shaped vehicle body to move horizontally back and forth, realizing reciprocating parallel grass feeding.
