Description

Technical Field

[0001] This utility model belongs to the technical field of Coptis chinensis planting, and more specifically, it relates to a Coptis chinensis planting ridging machine with a quick-release structure. Background Technology

[0002] Coptis chinensis, a perennial herb belonging to the genus Coptis in the family Ranunculaceae. Its leaves are long-petiolate, thinly leathery, ovate-pentagonal, cordate at the base, with petiolate segments; the middle segment is rhomboid-ovate, pinnately deeply lobed, with finely pointed teeth; bracts are narrow and long, pinnately divided; sepals are yellowish-green and lanceolate; petals are linear-lanceolate; the fruit is oblong; it flowers from February to March and fruits from April to July. The Compendium of Materia Medica records that "its roots are connected like beads and are yellow in color," hence the name Coptis chinensis. When planting Coptis chinensis, a ridging machine is needed to prepare the soil for ridging.

[0003] Currently, the ridging machine for Coptis chinensis planting needs to be towed by a tractor to move and to rid different locations. However, after ridging is completed, the operator needs to unload the ridging machine from the rear of the tractor. But currently, the disassembly of the ridging machine requires the use of appropriate tools, such as wrenches or pliers, to loosen and remove the cotter pins or retaining nuts on the pins connecting the ridging machine and the tractor, and then pull out multiple pins one by one. This increases the working time required for disassembling the ridging machine and makes it inconvenient for the operator to use the ridging machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a Coptis chinensis planting ridging machine with a quick-release structure. This solves the problem that existing technologies require tractor-traction for ridging at different locations, but after ridging, operators need to unload the ridging machine from the rear of the tractor. However, disassembling the ridging machine is currently very inconvenient, which increases the working time required for disassembly and makes it difficult for operators to use the machine.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a Coptis chinensis planting and ridging machine with a quick-release structure, comprising a machine body, the upper end of which is fixedly connected to a housing, the upper surface of which is rotatably connected to two connecting rods via pins, a column is mounted on the surface of one of the connecting rods, a locking post is movably inserted through a through hole on the surface of the column, a round block is mounted on one end of the locking post, the other end of the locking post movably inserts through the two connecting rods via a through hole, a spring is wound around the surface of the locking post, one end of the spring is fixedly connected to the locking post, the other end of the spring is fixedly connected to the column, the surface of the locking post contacts an insert rod through an insertion hole, and the insert rod penetrates the column through the through hole.

[0006] As a preferred embodiment of this utility model, a transmission component is installed on the upper surface of the machine body.

[0007] As a preferred embodiment of this utility model, a splined shaft is mounted on the surface of the transmission assembly, and four fixing blocks are mounted on the surface of the splined shaft. The surfaces of the four fixing blocks are respectively connected to the corresponding locking bolts through threaded holes.

[0008] As a preferred embodiment of this utility model, both ends of the machine body are rotatably connected to a rotating shaft via bearings, and multiple rotary tillage blades are mounted on the surface of the rotating shaft.

[0009] As a preferred embodiment of this utility model, the surfaces of both connecting rods are fixedly connected to the corresponding support frames, and the other ends of both support frames are fixedly connected to the machine body.

[0010] As a preferred embodiment of this utility model, curved plates are installed at the lower ends of both sides of the machine body, and soil retaining plates are installed on the surface of the machine body.

[0011] This utility model provides a Coptis chinensis planting and ridging machine with a quick-release structure, which has the following beneficial effects:

[0012] 1. This new type of machine, consisting of a body, housing, connecting rod, column, locking pin, round block, insert rod, and spring, allows the operator to connect the connecting rod to the rear of the tractor. First, the operator aligns the round hole at the rear of the tractor with the connecting rod. Then, the operator presses the round block, which moves the locking pin, allowing it to pass through the through-holes in both connecting rods and the rear of the tractor. Simultaneously, the locking pin compresses the spring. The operator then inserts the insert rod into the hole on the surface of the locking pin to fix its position. When ridging is complete and the ridging machine needs to be removed from the rear of the tractor, the operator pulls out the insert rod. The spring then returns to its original position, causing the locking pin to return to the column. The machine body can then be removed from the tractor. This method allows the ridging machine to be quickly removed from the rear of the tractor, reducing the time required for disassembly and making it easier for the operator to use the machine.

[0013] 2. By using the spline shaft, fixing block, and locking bolts, when the spline shaft is connected to the PTO shaft of the tractor, the operator rotates the four locking bolts. All four locking bolts are tightened against the PTO shaft, so that when the tractor moves the ridging machine, the PTO shaft will not fall off due to not being locked to the spline shaft, thus improving the working efficiency of the ridging machine.

[0023] Please see Figures 1 to 5This utility model provides a technical solution for a Coptis chinensis planting and ridging machine with a quick-release structure: it includes a body 1, the upper end of which is fixedly connected to a shell 2, which is fixed inside the body 1. Two bevel gears are placed inside the shell 2. The upper surface of the shell 2 is rotatably connected to two connecting rods 3 via pins. The connecting rods 3 rotate on the shell 2. A column 4 is mounted on the surface of one connecting rod 3. A locking post 5 is movably inserted through a through hole on the surface of the column 4. The locking post 5 moves through the column 4. A round block 6 is mounted on one end of the locking post 5 to facilitate the movement of the locking post 5. The other end of the locking post 5 movably inserts through the two connecting rods 3 via a through hole. A spring 8 is wound around the surface of the locking post 5. The spring 8 allows the locking post 5 to return to its original position after it is not fixed. One end of the spring 8 is fixedly connected to the locking post 5 and fixed to the locking post 5. The other end of the spring 8 is fixedly connected to the column 4 and fixed to the column 4. The surface of the locking post 5 contacts an insert rod 7 through an insertion hole. The insert rod 7 fixes the locking post 5 and passes through the column 4 via a through hole. When connecting rod 3 needs to be connected to the rear of the tractor, the operator first aligns the round hole at the rear of the tractor with connecting rod 3. Then, the operator presses the round block 6, which moves the locking pin 5 so that the locking pin 5 passes through the two connecting rods 3 and the through hole at the rear of the tractor. At the same time, the locking pin 5 presses the spring 8. Then, the operator inserts the insertion rod 7 into the insertion hole on the surface of the locking pin 5 to fix the position of the locking pin 5. When ridging is completed and the ridging machine needs to be removed from the rear of the tractor, the operator pulls out the insertion rod 7. At this time, the spring 8 returns to its original position, causing the locking pin 5 to return to the column body 4. At this time, the machine body 1 can be removed from the tractor. The above method allows the ridging machine to be quickly removed from the rear of the tractor, which reduces the time required for disassembling the ridging machine and makes it easier for the operator to use the ridging machine.

[0024] The upper surface of the machine body 1 is equipped with a transmission assembly 9, which includes a transmission shaft, two bevel gears, a rotating rod, two sprockets, and four chains. When the PTO shaft rotates, the PTO shaft drives the transmission shaft to rotate, the transmission shaft drives the two bevel gears to rotate, the bevel gears drive the rotating rod to rotate, and the two ends of the rotating rod drive the two sprockets in the housings on both sides of the machine body 1 to rotate. The two sprockets drive the other two sprockets to rotate through their corresponding chains, and the two sprockets drive the rotating shaft 13 to rotate. The rotating shaft 13 drives the rotary tiller blades 14 mounted on the surface to rotate.

[0025] The transmission assembly 9 has a splined shaft 10 mounted on its surface. The splined shaft 10 has four fixed blocks 11 mounted on its surface. The splined shaft 10 drives the fixed blocks 11 to rotate. The surfaces of the four fixed blocks 11 are respectively connected to the corresponding locking bolts 12 through threaded holes. The locking bolts 12 are rotated and tightened on the fixed blocks 11.

[0026] The two ends of the machine body 1 are rotatably connected to the rotating shaft 13 through bearings. The rotating shaft 13 rotates on the machine body 1, and multiple rotary tillage blades 14 are installed on the surface of the rotating shaft 13. The rotating shaft 13 drives the rotary tillage blades 14 to rotate.

[0027] The surfaces of the two connecting rods 3 are fixedly connected to the corresponding support frame 17, the support frame 17 fixes the angle of the connecting rods 3, and the other ends of the two support frames 17 are fixedly connected to the body 1.

[0028] The lower ends of both sides of the body 1 are equipped with curved plates 15, which can prevent the body 1 from being worn on the ground. The surface of the body 1 is equipped with a soil retainer 16, which can block the soil from being turned up and prevent soil from splashing.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In use, the operator first inserts the splined shaft 10 at the end of the transmission assembly 9 of the ridging machine into the PTO shaft at the rear of the tractor. Then, the four locking bolts 12 are tightened to secure the PTO shaft, preventing the splined shaft 10 from slipping out. Next, the through hole at the rear of the tractor is aligned with the through holes on the two connecting rods 3. The round block 6 is pressed, causing the locking pin 5 to move. As the locking pin 5 passes through the two connecting rods 3 and the tractor, it also presses the spring 8. The operator then inserts the insertion rod 7 into the column body 4, ensuring its end is inserted into the insertion hole on the surface of the locking pin 5, thus fixing its position. This completes the connection between the machine body 1 and the tractor. The PTO shaft of the tractor then begins to rotate, driving the transmission assembly 9 to rotate. The transmission assembly 9 includes a transmission... The machine consists of a drive shaft, two bevel gears, a rotating rod, two sprockets, and four chains. When the PTO shaft rotates, it drives the transmission shaft to rotate, which in turn drives the two bevel gears to rotate. The bevel gears then drive the rotating rod to rotate, and the two ends of the rotating rod drive the two sprockets inside the housings on both sides of the machine body 1 to rotate. Each of the two sprockets drives the other two sprockets to rotate via corresponding chains. The two sprockets then drive the rotating shaft 13 to rotate, which in turn drives the rotary tiller blades 14 mounted on the surface to rotate. The rotary tiller blades 14 perform ridging work on the ground. After ridging is completed, the operator closes the PTO shaft, then loosens the four locking bolts 12, and then removes the spline shaft 10 from the PTO shaft. The operator then removes the insert rod 7 from the column 4. At this time, the spring 8 returns to its original position, causing the locking pin 5 to move out of the through holes of the two connecting rods 3 and the tractor, completing the disassembly of the Coptis chinensis planting ridging machine.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
