Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a plowing device with protective functions. Background Technology

[0002] A tillage device is an agricultural machine used for turning and loosening soil. It consists of two parts: a power source and a tillage device. The power source is usually a tractor or other power unit, while the tillage device includes a plow blade, a frame, and a mounting base for mounting a traction device. The plow blade is fixed to the frame, and the frame is connected to the traction device through the mounting base. This structural design allows the tillage device to effectively turn and loosen the soil, thereby improving soil quality.

[0003] However, most existing plowing devices lack protective structures for the plow blades, making them prone to collisions with large stones during plowing, which in turn affects the efficiency and speed of tilling and causes additional economic losses. Therefore, we propose a plowing device with protective functions. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art where the atomizing nozzle is completely open, the sprayed water mist particles are easily affected by air flow, resulting in water mist dispersion, which leads to an unsatisfactory humidification effect on cotton yarn. In addition, a large amount of water may not be effectively utilized and evaporate or be lost, increasing the humidity of the surrounding environment and further increasing the risk of the spread of bacteria, viruses and other microorganisms in the air. Therefore, this invention proposes a plowing device with protective function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plowing device with protective function, comprising a fixed rod and a protective device, wherein the protective device is fixedly installed at one end of the fixed rod, the protective device comprising a first fixed plate and a second fixed plate, one end of the first fixed plate being fixedly connected to one end of the fixed rod, the second fixed plate being located on one side of the first fixed plate, both the first and second fixed plates having movable grooves in their middle portions, a cylinder being rotatably connected between the middle portions of the two movable grooves, an upper connecting rod being rotatably connected above the middle portions of the two movable grooves, a lower connecting rod being rotatably connected below the middle portions of the two movable grooves, a limiting plate being fixedly installed at the lower end of the movable groove located on one side of the second fixed plate, one side of the lower connecting rod abutting against the limiting plate, connecting plates being fixedly installed at the four corners of the second fixed plate, limiting holes being opened in the middle portions of the four connecting plates, and bolts being threadedly connected to the middle portions of the four limiting holes.

[0006] Preferably, the other end of the fixing rod is threadedly connected to a plow blade, and mounting plates are fixedly installed on both sides of the upper middle part of the plow blade.

[0007] Preferably, a plug is fixedly installed at one end of the fixing rod, and the plug is located in the middle of the two mounting plates.

[0008] Preferably, the insertion rod and the two mounting plates have through holes in their middle sections, and a fixing pin is threaded into the middle of the insertion holes.

[0009] Preferably, a support rod is fixedly installed at the middle of the lower end of the fixed rod, and a front cutter is threadedly connected to the lower end of the support rod. The front cutter is located directly in front of the plow blade.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a cylinder, a lower connecting rod, and an upper connecting rod that can drive the insert rod upward, the plow blade is protected. When plowing, the plow blade comes into contact with the soil. The drive device moves the device, and the plow blade can turn over and loosen the soil. When the plow blade encounters a large stone, the plow blade will first come into contact with the stone. Then, the upper connecting rod, the lower connecting rod, and the end of the cylinder that is in contact with the fixed plate will move upward, thereby driving the plow blade to move upward and jump over the stone. This protects the plow blade and avoids damage to the plow blade caused by large stones in the soil during plowing, thus preventing additional economic losses.

[0012] 2. In this utility model, a front-mounted blade is set in front of the plow blade. The front-mounted blade is detachable and can come into contact with the soil to loosen the soil when plowing. It can also come into contact with some stones that can damage the plow blade in advance, thereby playing a role in early warning and protecting the plow blade. Attached Figure Description

Limit holes 24 are opened in the middle of the four connecting plates 23. Bolts 25 are threadedly connected to the middle of the four limit holes 24.

[0021] The specific settings and functions of this embodiment are described in detail below. By setting up a cylinder 27, a lower connecting rod 28, and an upper connecting rod 29 that can drive the plow blade 15 upward, the plow blade 15 is protected. When plowing, the plow blade 15 comes into contact with the soil. The drive device moves the device, and the insert rod 13 can turn over and loosen the soil. When the plow blade 15 encounters a large stone, the plow blade 15 will first come into contact with the stone. Then, the end of the upper connecting rod 29, the lower connecting rod 28, and the cylinder 27 that is in contact with the fixing plate 21 will move upward, thereby driving the plow blade 15 upward and skipping over the stone. This protects the plow blade 15 and prevents large stones in the soil from damaging the plow blade 15 during plowing, thus avoiding additional economic losses.

[0022] Example 2, as Figure 1 , Figure 2 and Figure 3 As shown, the other end of the fixing rod 1 is threadedly connected to a plow blade 15. Mounting plates 16 are fixedly installed on both sides of the upper middle part of the plow blade 15. An insert rod 13 is fixedly installed on one end of the fixing rod 1. The insert rod 13 is located in the middle of the two mounting plates 16. An insertion hole 14 is opened through the middle of the insert rod 13 and the two mounting plates 16.

A front cutter 12 is threadedly connected to the lower end of the support rod 11. The front cutter 12 is located directly in front of the plow blade 15.

[0023] The overall effect of this embodiment is that by setting up a cylinder 27, a lower connecting rod 28, and an upper connecting rod 29 that can drive the plow blade 15 upward, the plow blade 15 is protected. When plowing, the plow blade 15 comes into contact with the soil. The drive device moves the plow blade, and the insert rod 13 can turn and loosen the soil. When the plow blade 15 encounters a large rock, it will first contact the rock. Then, the end of the upper connecting rod 29, the lower connecting rod 28, and the cylinder 27 that contacts the fixing plate 21 will move upward, thereby driving the plow blade 15 upward and allowing it to jump over the rock, thus protecting the plow blade 15 and preventing... To address the issue of larger stones damaging the plow blade 15 during tilling, resulting in additional economic losses, a limiting plate 30 is installed at the lower end of the fixing plate 22 to block and limit the lower connecting rod 28. The limiting plate 30 stabilizes the posture of the entire protection device 2, preventing it from tilting downwards. Furthermore, a front blade 12 is installed in front of the plow blade 15. The front blade 12 is detachable and can make contact with the soil before tilling to loosen the soil. It can also make contact with stones that could damage the plow blade 15 in advance, thus serving as a warning and protecting the plow blade 15.

[0024] The device's operation and working principle are as follows: By incorporating a cylinder 27, a lower connecting rod 28, and an upper connecting rod 29 that drive the plow blade 15 upwards, the plow blade 15 is protected. During plowing, the plow blade 15 contacts the soil. The drive mechanism moves the device, and the insert rod 13 turns and loosens the soil. When the plow blade 15 encounters a large rock, it first contacts the rock. Subsequently, the end of the upper connecting rod 29, lower connecting rod 28, and cylinder 27 that contacts the fixed plate 21 moves upwards, thereby driving the plow blade 15 upwards. Skipping over stones serves to protect the plow blade 15. A limiting plate 30 is also installed at the lower end of the fixing plate 22 to block and limit the lower connecting rod 28. The limiting plate 30 stabilizes the posture of the entire protective device 2, preventing it from tilting downwards. Furthermore, a front-mounted blade 12 is installed in front of the plow blade 15. This front-mounted blade 12 is detachable and can contact the soil beforehand to loosen it during plowing. It can also contact stones that could damage the plow blade 15 in advance, thus providing early warning and protection for the plow blade 15.
