Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and in particular to a multi-purpose excavator. Background Technology

[0002] Tillage is a soil cultivation method that uses agricultural tools such as plows to shovel, loosen, and turn over soil clods. Tillage refers to shoveling, breaking up, and clearing the land to make it flat and loose. It is the most basic process for farmers to cultivate the land. Tillage allows seeds to breathe in the soil and grow more easily. Excavators are machines used for tillage. Excavators are often used for tillage in the process of soil remediation in agricultural planting.

[0003] When the excavator is working, the movable machine body moves and controls the soil-turning structure of the turning blade to penetrate into the soil. The turning blade turns the soil as it rotates. However, the turning blade is only suitable for relatively soft soil. When the turning blade turns the soil on harder soil, the soil clods are larger. Moreover, when the turning blade directly turns a large area of ​​hard soil, it is easy to damage the turning blade. Therefore, a multi-purpose excavator is proposed. Utility Model Content

[0004] Given that the existing soil turning blades are only suitable for turning over relatively soft soil, and that when turning over harder soil, the soil clods turned over are larger, and that the soil turning blades are easily damaged when turning over large areas of hard soil, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-purpose excavator, comprising a support body, two power-moving structures mounted on the bottom surface of the support body, a double-bar frame disposed between the two power-moving structures, a tension telescopic rod fixedly connected to the upper surface of the double-bar frame, the upper end of the tension telescopic rod being fixedly connected to the bottom surface of the support body, a power telescopic structure mounted on the bottom surface of the support body, the power telescopic structure being connected to the upper surface of the double-bar frame, a mounting frame disposed below the double-bar frame, two sleeve plates slidably fitted onto the outer surface of the double-bar frame, each sleeve plate being elastically connected to the mounting frame via multiple elastic telescopic rods. Multiple longitudinal shafts are rotatably inserted inside the mounting frame. A flat plate is set below the longitudinal shafts and is fixedly inserted inside the mounting frame. A push spring is fixedly connected to one end of the double rod frame and slides on the outer surface of the double rod frame. The other end of the push spring is fixedly connected to the side of a sleeve plate. Multiple drilling shaft plates rotatably pass through the bottom surface of the flat plate. A bevel gear A is fixedly sleeved at the end of the drilling shaft plate above the flat plate. A bevel gear B meshes above bevel gear A and is fixedly sleeved on the outer surface of the adjacent longitudinal shaft. A multi-axis output power box is fixedly installed on the front of the mounting frame. The front end of each longitudinal shaft is fixedly connected to the output end of the multi-axis output power box.

[0006] Preferably, the power telescopic structure includes a dual-axis output power box, two cylinders and two bent rods. The two bent rods are located below the two cylinders respectively. Both cylinders are rotatably connected to the support body. The dual-axis output power box is fixedly connected to the support body. The front ends of the two cylinders are fixedly connected to the output end of the dual-axis output power box. Two curved blocks are fixedly connected to the circumferential side of the cylinders.

[0007] Preferably, one side of the curved block is curved, and the other side of the curved block is a plane whose extension line coincides with the axis of the cylinder. Two curved blocks connected to the same cylinder are distributed in an array along their axes.

[0008] Preferably, the two sleeve plates are arranged in parallel, and the other side of the sleeve plate connected to the push spring is a sleeve-shaped structure, with the push spring located inside the sleeve-shaped structure of the sleeve plate.

[0009] Preferably, the axis of the longitudinal axis intersects perpendicularly with the axis of the soil drilling plate located directly below, and multiple longitudinal axes are distributed at equal intervals.

[0010] Preferably, multiple drilling shaft plates connected to the same flat plate are evenly distributed at equal distances.

[0011] Preferably, the drilling shaft plate is arranged in a spiral shape, and the lower end of the drilling shaft plate is conical.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up push springs, sleeve plates, mounting frames, and drilling shaft plates, the multi-axis output power box drives the drilling shaft plates to rotate through transmission when the equipment moves. As the power telescopic structure controls the double rod frame to move downward, the rotating shaft plates gradually insert into the soil, initially dividing the soil into multiple parts. At the same time, as the support body moves, the sleeve plates gradually compress the push springs. When the power telescopic structure controls the double rod frame to move upward and separate from the soil, the sleeve plates move back to the left side of the double rod frame under the push spring. As the double rod frame moves up and down repeatedly, multiple drilling shaft plates continuously separate the soil, facilitating the subsequent soil turning structure.

[0014] 2. By setting up a cylinder, a bent rod, and a curved block, when the upper end of the bent rod contacts the circumferential surface of the cylinder, the drilling shaft plate is located above the soil. As the cylinder rotates, the curved surface of the curved block contacts the bent rod, gradually pushing the double-rod frame downwards, causing the drilling shaft plate to gradually drill into the soil. When the bent rod moves out of the plane of the curved block, the tension telescopic rod pulls the double-rod frame, causing the bent rod to move quickly upwards and contact the circumferential surface of the cylinder, causing the drilling shaft plate to quickly separate from the soil.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1-5This invention provides a multi-purpose excavator, comprising a support body 1. Two power-driven moving structures 2 are mounted on the bottom surface of the support body 1. Soil-turning structures can be installed on the left and right sides of the support body 1. The power-driven moving structures 2 can drive the support body 1 to move. A double-bar frame 3 is provided between the two power-driven moving structures 2. A tension telescopic rod 5 is fixedly connected to the upper surface of the double-bar frame 3. The upper end of the tension telescopic rod 5 is fixedly connected to the bottom surface of the support body 1. A power telescopic structure 4 is mounted on the bottom surface of the support body 1 and connected to the upper surface of the double-bar frame 3. The power telescopic structure 4 includes a dual-shaft output power box 41, two cylinders 42, and two... Two bent rods 43 are located below two cylinders 42 respectively. Both cylinders 42 are rotatably connected to the support body 1. The dual-axis output power box 41 is fixedly connected to the support body 1. The front ends of the two cylinders 42 are fixedly connected to the output end of the dual-axis output power box 41. Two curved blocks 44 are fixedly connected to the circumferential side of the cylinders 42. One side of the curved block 44 is curved, and the other side of the curved block 44 is a plane whose extension line coincides with the axis of the cylinder 42. The two curved blocks 44 connected to the same cylinder 42 are distributed in an array along their axes. After the bent rod 43 is separated from the plane end of the curved block 44, the tension telescopic rod 5 can pull the double rod frame 3 to move upward quickly.

[0025] A mounting frame 6 is provided below the double rod frame 3. Two sleeve plates 7 are slidably sleeved on the outer surface of the double rod frame 3. Each sleeve plate 7 is elastically connected to the mounting frame 6 through multiple elastic telescopic rods 9. Multiple longitudinal shafts 8 are rotatably inserted inside the mounting frame 6. A flat plate 11 is provided below the longitudinal shaft 8. The flat plate 11 is fixedly inserted inside the mounting frame 6. A push spring 10 is fixedly connected to one end of the double rod frame 3. The push spring (10) is slidably sleeved on the outer surface of the double rod frame (3). The other end of the push spring 10 is fixedly connected to the side of a sleeve plate 7. The push spring 10 has the tendency to push the sleeve plate 7 to the left. The two sleeve plates 7 are arranged in parallel. The other side of the sleeve plate 7 connected to the push spring 10 is a sleeve-shaped structure. The push spring 10 is located inside the sleeve-shaped structure of the sleeve plate 7. When the right sleeve plate 7 moves to the right, the push spring 10 can retract into the sleeve-shaped structure of the sleeve plate 7 to prevent damage to the push spring 10.

[0026] Multiple drilling shaft plates 12 rotate through the bottom surface of the flat plate 11. As the drilling shaft plates 12 drill into the soil, the speed at which the power-moving structure 2 drives the support body 1 ensures that the sleeve plate 7 will not contact the right end of the double-rod frame 3, preventing the drilling shaft plates 12 from being subjected to excessive lateral force and breaking. When the drilling shaft plates 12 encounter significant resistance while drilling into the soil, the elastic telescopic rod 9 provides cushioning through compression. However, the elasticity of the elastic telescopic rod 9 is strong enough to push the drilling shaft plates 12 into the soil. Multiple drilling shaft plates 12 connected to the same flat plate 11 are evenly distributed at equal intervals and arranged in a spiral shape. The lower end of the soil drilling plate 12 is tapered to facilitate drilling into the soil. A bevel gear A13 is fixedly sleeved on one end of the soil drilling plate 12 above the plate 11. A bevel gear B14 meshes above the bevel gear A13. The bevel gear B14 is fixedly sleeved on the outer surface of the adjacent longitudinal shaft 8. The axis of the longitudinal shaft 8 intersects perpendicularly with the axis of the soil drilling plate 12 located directly below. Multiple longitudinal shafts 8 are distributed at equal distances. A multi-axis output power box 15 is fixedly installed on the front of the mounting frame 6. The front end of each longitudinal shaft 8 is fixedly connected to the output end of the multi-axis output power box 15. The multi-axis output power box 15 can drive multiple longitudinal shafts 8 to rotate synchronously.

[0027] During use, the power moving structure 2 drives the supporting body 1 to move, and the multi-axis output power box 15 is activated to drive the longitudinal shaft 8 to rotate. The bevel gear B14 rotates synchronously with the longitudinal shaft 8 and meshes with the bevel gear A13 to drive the drilling shaft plate 12 to rotate. The dual-axis output power box 41 is activated to drive the two cylinders 42 to rotate synchronously. When the upper end of the bent rod 43 contacts the circumferential surface of the cylinder 42, the drilling shaft plate 12 is located above the soil. As the cylinder 42 rotates, the curved surface of the curved block 44 contacts the bent rod 43, gradually pushing the double rod frame 3 downward, so that the drilling shaft plate 12 gradually drills into the soil. As the supporting body 1 moves synchronously, the sleeve plate 7 gradually compresses the push spring 10. When the bent rod 43 moves out of the plane of the curved block 44, the tension telescopic rod 5 pulls the double rod frame 3 to drive the bent rod 43 to move quickly upward and contact the circumferential surface of the cylinder 42, causing the drilling shaft plate 12 to quickly separate from the soil. The sleeve plate 7 moves back to the left side of the double rod frame 3 and resets under the push of the push spring 10. As the cylinder 42 drives the curved block 44 to continuously contact the bent rod 43, the double rod frame 3 moves up and down repeatedly, and multiple drilling shaft plates 12 continuously separate the soil, which facilitates the later soil turning structure.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
