Description

Technical Field

[0001] This utility model relates to the field of soil activation technology, specifically a multi-functional integrated soil activation machine. Background Technology

[0002] Soil activation, also known as soil improvement, plays an important role in tobacco field construction and tobacco planting. Multifunctional integrated soil activation machines typically integrate multiple functions to improve soil quality, promote crop growth, and reduce the labor intensity of tobacco farmers.

[0003] In the prior art, a patent application with application number CN202222638654.X, published by the China National Intellectual Property Administration, discloses a multi-functional integrated soil improvement machine. This machine includes a tractor body and a plow blade device located at the front end of the tractor body. A fixed frame is fixedly connected to the rear end of the tractor body, and a vertically arranged mixing box is fixedly connected to the side wall of the fixed frame. A central connecting pipe is fixedly connected to the top of the mixing box, and a feeding box is fixedly connected to the top of the central connecting pipe. A discharge box with an opening at the bottom is fixedly connected to the bottom of the mixing box. The internal space of the feeding box is divided into multiple storage chambers by partitions. Each storage chamber has a discharge port at its bottom that communicates with the interior of the central connecting pipe. Multiple insert plates are inserted through the side wall of the central connecting pipe, each covering the discharge port at the bottom of one of the storage chambers. This invention simultaneously solves soil tillage, soil improvement, soil fertilization, and soil pest and disease control, greatly improving work efficiency.

[0004] However, when the multi-functional soil improvement machine is performing soil activation operations, the depth to which the plow blades penetrate the soil is determined by the height of the handlebars fixed on the tractor body. The higher the handlebars are raised, the lower the height of one end of the plow blades, and the deeper they penetrate the soil. In the existing technology, the height of the handlebars is entirely controlled by the operator. This means that the operator has to push the tractor body forward while trying to keep the handlebars at the required height, which is not only more strenuous but also makes it difficult to ensure the accuracy of the height, resulting in uneven soil turning depth. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional integrated soil activation machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional integrated soil activation machine, comprising: a tractor body, a front wheel disposed on the surface of the tractor body, a handrail fixed to one end of the tractor body, a rear wheel bracket fixed to the surface of the handrail, a telescopic rod movably inserted into the bottom end of the rear wheel bracket, a rear wheel rotatably connected to the surface of the telescopic rod, and a height adjustment mechanism disposed between the rear wheel bracket and the telescopic rod.

[0007] Preferably, the rear wheel brackets are provided in two sets, and the two sets of rear wheel brackets are symmetrically distributed about the handrail.

[0008] Preferably, the height adjustment mechanism includes: a limiting rod, the limiting rod having a "T"-shaped round rod structure, one end of the thin rod of the limiting rod being movably inserted into the limiting groove, and the other end of the thin rod of the limiting rod being movably inserted into the limiting rod mounting hole.

[0009] Preferably, the limiting groove has a circular groove structure, and several sets of limiting grooves are provided, which are distributed vertically on the surface of the telescopic rod.

[0010] Preferably, the mounting hole of the limiting rod is a circular hole structure, and the mounting hole of the limiting rod is opened on the surface of the rear wheel bracket.

[0011] Preferably, a sleeve is fixed on the surface of the rear wheel bracket, the thicker part of the limiting rod is movably inserted into the sleeve, one end of the limiting rod extending into the sleeve is fixed with a spring and a pull rod, the other end of the spring is fixed on the inner wall of the sleeve, and the other end of the pull rod is movably inserted into the surface of the sleeve away from the rear wheel bracket.

[0012] Preferably, the telescopic rod has a "T"-shaped rectangular rod structure, and a pull rod is fixed at the top of the telescopic rod. The top of the pull rod is movably inserted into the top surface of the rear wheel bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The soil activation multi-functional integrated machine proposed in this utility model allows for adjustment of the plow blade's insertion depth into the soil layer. Simply adjust the length of the telescopic rod extending beyond the rear wheel support. The rear wheel support, telescopic rod, and rear wheel together lift the handle to the desired height. This change in handle height causes the tractor body to rotate around the front wheel axle, thereby adjusting the plow blade's height in the opposite direction, achieving the desired insertion depth. After adjustment, the height adjustment mechanism limits the telescopic rod to the required extension length, further restricting the plow blade's insertion depth. Then, the tractor's power unit drives the front wheel forward, simultaneously rotating the blade shaft. The plow blade penetrates the soil, tilling it. The front and rear wheels maintain the machine's balance, allowing the operator to easily push forward by holding the handle. This makes the soil activation multi-functional integrated machine more labor-saving to use, and ensures more precise plow blade insertion depth and more uniform tilling depth.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1 to 3This utility model provides a technical solution: a multi-functional integrated soil activation machine, comprising: a tractor body 1, a front wheel 2 disposed on the surface of the tractor body 1, and a handle 3 fixed to one end of the tractor body 1. The feature is that: a rear wheel bracket 4 is fixed to the surface of the handle 3, a telescopic rod 5 is movably inserted into the bottom end of the rear wheel bracket 4, a rear wheel 6 is rotatably connected to the surface of the telescopic rod 5, a height adjustment mechanism is provided between the rear wheel bracket 4 and the telescopic rod 5, and two sets of rear wheel brackets 4 are provided, the two sets of rear wheel brackets 4 being symmetrically distributed about the handle 3.

[0021] In actual use, when adjusting the depth of the plow blades inserted into the soil, this multi-functional soil activation machine only requires adjusting the length of the extension rod 5 extending from the rear wheel bracket 4. The rear wheel bracket 4, extension rod 5, and rear wheel 6 together lift the handle 3 to the required height. The change in the height of the handle 3 causes the tractor body 1 to rotate around the axle of the front wheel 2, thereby adjusting the height of the plow blades in the opposite direction, so that the depth of the plow blades inserted into the soil reaches the required level. After adjustment, the extension rod 5 is limited to the required extension length by the height adjustment mechanism, thus limiting the depth of the plow blades inserted into the soil. Then, the power unit on the tractor body 1 drives the front wheel 2 forward and simultaneously drives the blade shaft to rotate, causing the plow blades to penetrate the soil and till it. The front wheel 2 and rear wheel 6 can maintain the front-rear balance of the machine. The operator only needs to easily hold the handle 3 and push it forward. This makes the use of the multi-functional soil activation machine more labor-saving and makes the depth of the plow blades inserted into the soil more precise and the tilling depth more uniform.

[0022] Example 2: Based on Example 1, in order to realize the control of the height adjustment mechanism, the height adjustment mechanism includes: a limiting rod 9, the limiting rod 9 has a "T"-shaped round rod structure, one end of the thin rod of the limiting rod 9 is movably inserted into the limiting groove 7, and the other end of the thin rod of the limiting rod 9 is movably inserted into the limiting rod mounting hole 8, the limiting groove 7 has a circular groove structure, and several sets of limiting grooves 7 are provided, the several sets of limiting grooves 7 are distributed vertically on the surface of the telescopic rod 5, and the limiting rod mounting hole 8 has a circular hole structure, the limiting rod mounting hole 8 is opened in the rear wheel bracket. On the surface of the rear wheel bracket 4, a sleeve 10 is fixed. The thick rod of the limiting rod 9 is movably inserted into the sleeve 10. One end of the limiting rod 9 that extends into the sleeve 10 is fixed with a spring 11 and a pull rod 12. The other end of the spring 11 is fixed to the inner wall of the sleeve 10. The other end of the pull rod 12 is movably inserted into the surface of the sleeve 10 at the end away from the rear wheel bracket 4. The telescopic rod 5 has a "T"-shaped rectangular rod structure. The top end of the telescopic rod 5 is fixed with a lifting rod 13. The top end of the lifting rod 13 is movably inserted into the top surface of the rear wheel bracket 4.

[0023] When adjusting the extension length of the telescopic rod 5, the height adjustment mechanism must first release the limit on the telescopic rod 5. To release it, pull the lever 12 outwards. The lever 12 drives the limiting rod 9 out of the limiting groove 7 and the limiting rod mounting hole 8 and fully retracts into the sleeve 10, thereby releasing the limit on the telescopic rod 5. At this time, the spring 11 is compressed. Then, press down hard on the lifting rod 13 so that the rear wheel 6 is always against the ground. At the same time, hold the handrail 3 and move the handrail 3 up or down to change the height of the rear wheel bracket 4, thereby extending the telescopic rod 5 out of the rear wheel bracket. Adjust the length of frame 4 to the desired length, then release the pull rod 12. The spring 11, under its own elasticity, pushes the thin rod of the limiting rod 9 into the limiting rod mounting hole 8 and presses it against the surface of the telescopic rod 5. Then, slightly move the handle 3 so that the limiting rod mounting hole 8 is aligned with the nearest set of limiting grooves 7. The spring 11 then inserts one end of the thin rod of the limiting rod 9 into the new limiting groove 7, while the other end remains in the limiting rod mounting hole 8, restoring the limitation on the length of the telescopic rod 5 extending out of the rear wheel bracket 4. This completes the operation of the height adjustment mechanism.

[0024] In actual use, when adjusting the depth of the plow blades inserted into the soil, this multi-functional soil activation machine only requires adjusting the length of the extension rod 5 extending beyond the rear wheel bracket 4. The rear wheel bracket 4, extension rod 5, and rear wheel 6 together lift the handle 3 to the required height. This change in the height of the handle 3 causes the tractor body 1 to rotate around the axle of the front wheel 2, thereby adjusting the height of the plow blades in the opposite direction, allowing the plow blades to penetrate the soil to the desired depth. After adjustment, the height adjustment mechanism limits the extension rod 5 to the required extension length, thus restricting the depth of the plow blades inserted into the soil. Then, the power unit on the tractor body 1 drives the front wheel 2 forward, simultaneously rotating the blade shaft. The plow blades penetrate the soil to till it. The front wheel 2 and rear wheel 6 maintain the front-rear balance of the machine, and the operator only needs to easily hold the handle 3 and push it forward. This makes the use of the multi-functional soil activation machine more labor-saving, and makes the depth of plow blade insertion into the soil more precise and the tilling depth more uniform. When it is necessary to adjust the extension length of the extension rod 5... To release the height adjustment mechanism's restriction on the telescopic rod 5, pull the lever 12 outwards. The lever 12 will cause the limiting rod 9 to retract completely into the sleeve 10, thus releasing the restriction on the telescopic rod 5. At this time, the spring 11 is compressed. Then, press the lifting lever 13 downwards to keep the rear wheel 6 pressed against the ground. At the same time, hold the handrail 3 and move it up or down to change the height of the rear wheel bracket 4, thereby adjusting the length of the telescopic rod 5 extending beyond the rear wheel bracket 4. After adjusting to the desired length, release the pull rod 12. The spring 11, under its own elasticity, pushes the thin rod of the limiting rod 9 into the limiting rod mounting hole 8 and presses it against the surface of the telescopic rod 5. Then, slightly move the handle 3 to align the limiting rod mounting hole 8 with the nearest set of limiting grooves 7. The spring 11 then inserts one end of the thin rod of the limiting rod 9 into the new limiting groove 7, while the other end remains in the limiting rod mounting hole 8, restoring the limitation on the length of the telescopic rod 5 extending out of the rear wheel bracket 4. This completes the operation of the height adjustment mechanism.
