Description

Technical Field

[0001] The invention relates to the technical field of desert control equipment, in particular to a traction-type grass-laying and grass-pressing integrated machine. Background Art

[0002] The spread and intensification of land desertification poses a huge threat to the sustainable development of my country's economy and society. How to resist the spread and intensification of land desertification while protecting the desert ecological environment is an issue that we urgently need to solve.

[0003] The grass grid sand barrier is a method of sand control that can prevent wind and fix sand, as well as conserve water. It uses wheat straw, rice straw, reeds and other materials to form a grid shape in the desert. The grass grid sand barrier can make the ground rough, block sand and reduce wind force, and it can also intercept water, such as rainwater, to increase the water content of the sand layer, which is conducive to the survival of sand-fixing plants. The grid sand control method is one of the very effective ways for China to control deserts. Previously, manual methods were used, which were costly, slow and inefficient. Although the "three-dimensional sand-fixing vehicle" later achieved remarkable results, for the complex conditions of sand, my country still needs small desert grass-laying machines that are easy to operate.

[0004] The straw laying machine in the traditional technology cannot achieve uniform laying of the straw when laying the straw, and the construction quality and efficiency are low.

[0005] Therefore, the towed grass paving and pressing machine has become an urgent problem to be solved by the whole society. Summary of the invention

[0006] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a traction-type grass-laying and grass-pressing integrated machine, comprising a main frame and a traction frame, wherein the traction frame is connected to the rear end of the main frame and is used to connect to a tractor to tow the tractor, an operating platform is arranged on the side of the main frame away from the traction frame, an artificial seat is arranged on the operating platform, a grass-laying system and a grass-pressing system are arranged on the main frame, the grass-laying system comprises a grass inlet, a conveyor belt, a crankshaft, an engine and a multi-channel grass-combing fork, the conveyor belt comprises an upper conveyor belt with a lifting belt and a lower conveyor belt with a lifting belt, the bottom end of the upper conveyor belt with a lifting belt is arranged in the middle of the inclined surface of the lower conveyor belt with a lifting belt, the crankshaft is connected to the engine and driven by the engine, and its top end is used to control the central axis of the multi-channel grass-combing fork to realize the grass-combing process;

[0007] The grass pressing system includes two groups of grass pressing plates, a grass pressing plate and a tire lifting device. The grass pressing plate is arranged at the bottom end of the inclined surface of the belt-lifting conveyor belt. The two groups of grass pressing plates are respectively arranged at the two ends of the grass pressing plate in a symmetrical structure. The tire lifting device is connected to the two ends of the main frame. The bottom edge of the grass pressing plate is lower than the bottom edge of the grass pressing plate.

[0008] Furthermore, the multi-channel grass plucking fork includes primary grass plucking comb teeth, secondary grass plucking comb teeth and tertiary grass plucking comb teeth, both sides of the central axis of the primary grass plucking comb teeth, secondary grass plucking comb teeth and tertiary grass plucking comb teeth are connected to the crankshaft, and the spacing between two adjacent groups of grass plucking comb teeth is equal.

[0009] The advantages of the invention compared with the prior art are:

[0010] The present invention combines a total vehicle frame, a traction frame, a grass laying system and a grass pressing system. Through three grass combing forks that continuously swing back and forth on the conveyor belt, the grass can be evenly laid on the conveyor belt. The rice straw can be evenly laid on the ground according to the design requirements, thereby improving the quality and efficiency of rice straw laying.

[0011] The straw pressing system of the present invention adopts a combination of two groups of straw fixing pressing plates, a straw pressing plate and other structures. The straw pressing plate presses the middle part of the straw to a depth of 15-20 cm below the ground from between the two straw fixing tooth plates to form a double-layer foldable vertical straw sand barrier.

[0012] The present invention adopts a tire lifting device, which can adjust the height of the corresponding running wheel to meet the grass laying requirements of different sites. BRIEF DESCRIPTION OF THE DRAWINGS
