Description

Technical Field

[0001] The invention relates to the technical field of crawler power chassis, in particular to a remote-controlled extended-range crawler power chassis suitable for hilly and mountainous areas. Background Art

[0002] A crawler powered chassis is a type of chassis that supports the weight of a vehicle or mechanical equipment and moves on the ground through a series of chain links and drive wheels; it is mainly used in the military, agriculture, construction, and engineering fields; hilly and mountainous areas usually have thicker soil layers, which provide good soil conditions for the development of agriculture, and crawler powered chassis are needed to assist in sowing in hilly and mountainous areas;

[0003] Due to the abundant precipitation in hilly and mountainous areas, sudden and short rain may occur during the operation of the tracked power chassis. Rainwater can easily pass through the surface of the tracked power chassis, causing interference to its internal electronic equipment and batteries, and affecting the normal operation of the tracked power chassis. At the same time, due to the small undulations in the hilly and mountainous areas, the drainage in the hilly and mountainous areas is usually not as fast as that in the mountains. Temporary water accumulation will form when it rains, and the tracked power chassis can easily sink into the waterlogged soil, making it inconvenient to effectively clean it up later. Moreover, the existing remote-controlled agricultural machinery in hilly and mountainous areas is relatively large in size and requires multiple people to operate, resulting in insufficient labor and low applicability. Summary of the invention

[0004] The technical problems solved by this solution are:

[0005] (1) How to solve the problem that rainwater easily penetrates the surface of the crawler power chassis, causing interference with the electronic equipment and batteries inside, affecting the normal operation of the crawler power chassis;

[0006] (2) How to solve the problem that temporary water accumulation occurs when it rains, and the tracked power chassis is easily sunk into the soil, making it difficult to effectively clean it up later.

[0007] (3) How to solve the problem that existing remote-controlled agricultural machinery in hilly and mountainous areas is too large in size, requires multiple people to operate, causes labor shortage, and has low applicability.

[0008] The object of the present invention can be achieved by the following technical scheme: a remote-controlled extended-range crawler power chassis suitable for hilly and mountainous areas, comprising a power chassis body, mud guards are arranged on both the front and rear sides of the middle part of the power chassis body, a crawler tooling is rotatably arranged below the mud guards, a waterproof mechanism for preventing water from entering the top of the power chassis body is arranged on the top of the two mud guards, and a supporting mechanism for lifting the power chassis body is arranged below the waterproof mechanism;

[0009] The waterproof mechanism includes an air cylinder fixedly arranged on the top of the fender, a first electric push rod arranged laterally is fixedly installed on the fender on one side of the air cylinder, the extended end of the first electric push rod is fixedly connected to a push-pull rod, one end of the push-pull rod movably passes through the air cylinder and is fixedly connected to a piston, and the piston is slidably connected to the inner wall of the air cylinder.

[0010] A further technical improvement of the present invention is that a rotating base is fixedly provided on the side of the first electric push rod away from the power chassis body, a flip rod is rotatably provided on the top of the rotating base, a rain shield is fixedly connected to the top of the two flip rods, and a guide plate is fixedly provided on the side of the rain shield.

[0011] A further technical improvement of the present invention is that the middle part of the flip rod is fixedly connected to the fender through a tension spring, a positioning block for limiting the rotation angle of the flip rod is also fixedly installed on the fender, and a shift rod is also fixedly installed on the protruding end of the first electric push rod, and the position of the shift rod corresponds to the position of the flip rod.

[0012] A further technical improvement of the present invention is that: a connecting pipe is fixedly connected to the bottom of the air storage cylinder, and a connection between the connecting pipe and the air storage cylinder is arranged near the rotating base; by controlling the extended ends of the two first electric push rods to shrink from the longest to the shortest, the two levers drive the corresponding flip rods to rotate, so that the rain shield provides shielding for the top of the power chassis body, and the rain shield cooperates with the guide plate to divert rainwater, reducing rainwater from passing through the surface of the power chassis body and interfering with the electronic equipment and batteries inside it, thereby preventing the normal operation of the power chassis body from being affected. At the same time, two positioning blocks are used to provide a limit to the bottom of the corresponding flip rod to prevent the rain shield and the guide plate from over-flipping, thereby ensuring that the rain shield and the guide plate provide good waterproofing for the power chassis body.

[0013] A further technical improvement of the present invention is that the supporting mechanism includes two slots, a leather bag is arranged inside the slot, one end of the connecting tube is fixedly connected to one of the leather bags, and the middle part of the connecting tube is connected to an L-shaped tube, and one end of the L-shaped tube is fixedly connected to the other leather bag.

[0014] A further technical improvement of the present invention lies in that: mounting frames are provided on both the front and rear sides of the power chassis body, one end of the mounting frame passes through the corresponding crawler tooling and is fixedly connected to the bottom of the power chassis body, and both sides of the bottom of the mounting frame are fixedly connected to two slots; in the process of the extended end of the first electric push rod being retracted to the shortest, the piston is driven to move by the push-pull rod to squeeze the air in the air storage cylinder, so that the air in the air storage cylinder is injected into the two bladders through the connecting pipe and the L-shaped pipe, thereby increasing the volume of the two bladders, and cooperating with the corresponding slots to provide support for the bladders, so that the four bladders lift the power chassis body, increase the distance between the power chassis body and the soil, prevent the power chassis body from sinking into the waterlogged soil, and facilitate subsequent effective cleaning.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the present invention is in use, by controlling the extended ends of the two first electric push rods to shrink from the longest to the shortest, the two levers drive the corresponding flip rods to rotate, so that the rain shield provides shielding for the top of the power chassis body, and the rain shield cooperates with the guide plate to guide rainwater away, thereby reducing rainwater from passing through the surface of the power chassis body and interfering with the electronic equipment and batteries inside it, thereby preventing the normal operation of the power chassis body from being affected. At the same time, two positioning blocks are used to provide a limit to the bottom of the corresponding flip rod to prevent the rain shield and the guide plate from over-turning, thereby ensuring that the rain shield and the guide plate provide good waterproofing for the power chassis body.

[0017] When the present invention is in use, when the extended end of the first electric push rod is contracted to the shortest, the push-pull rod drives the piston to move, squeezes the air in the air storage cylinder, and injects the air therein into the two bladders through the connecting pipe and the L-shaped pipe, thereby increasing the volume of the two bladders, and cooperating with the corresponding card slots to provide support for the bladders, so that the four bladders lift the power chassis body, increase the distance between the power chassis body and the soil, prevent the power chassis body from sinking into the waterlogged soil, and facilitate subsequent effective cleaning.

[0018] When the present invention is in use, the small size of the power chassis body not only reduces the difficulty of manual operation and the labor intensity, but also prevents the phenomenon of corn being easily crushed when turning. When the extended ends of the two first electric push rods are extended to the longest state, the lever and the flip rod are not in contact. Through the tension of the tension spring, the flip rod is folded and the rain shield is close to the power chassis body, so that the whole machine has a high degree of integration and meets the requirements of use in hilly and mountainous areas.
