Description

Technical Field

[0001] This utility model relates to the field of agricultural and forestry machinery, and more specifically to a floating contour coppicing machine. Background Technology

[0002] In traditional agricultural and forestry coppicing operations, common coppicing machines are mainly divided into two categories: ordinary coppicing machines and hydraulic contour coppicing machines. Ordinary coppicing machines cut at a single height using fixed blades. Although they are simple in structure and easy to operate, they often struggle to guarantee coppicing quality when faced with undulating terrain or uneven crop stubble height, easily resulting in stubble that is too high or too low.

[0003] Hydraulic contour cutting machines attempt to use a hydraulic system to move the blades up and down to adapt to uneven terrain. However, their contouring effect relies primarily on the single-direction hydraulic cylinder thrust adjustment, failing to accommodate the complex changes in both the longitudinal (vertical) and lateral (lateral) terrain. Especially when operating on slopes or irregular surfaces, problems such as uneven cutting flatness and secondary damage to crop roots still occur. This contouring control method is essentially a passive response to ground undulations, lacking proactive adaptation to changes in the lateral terrain angle.

[0004] Therefore, how to provide a new floating contouring coping machine that can contour the ground at an angle to the side of the power head is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a floating contour-following coppicing machine, which aims to solve the technical problem that the traditional contour-following coppicing machine lacks active adaptability to changes in lateral terrain angle.

[0006] A floating contour coping machine includes:

[0007] The power head travels in a forward-backward direction.

[0008] The hydraulic control mechanism has its fixed end fixedly connected to the front end of the power head;

[0009] A floating connector is fixed to the drive end of the hydraulic control mechanism and floats up and down along the height direction of the power head.

[0010] The floating frame has a fixed end and a floating end, which are arranged on both sides perpendicular to the forward direction of the power head. The fixed end is fastened to the floating connector and the bottom end is rotatably connected to a conformal wheel.

[0011] The second conformal ground wheel is rotatably connected to the floating end to drive the floating end of the floating frame to float up and down;

[0012] The cutting mechanism includes a mounting frame, a hydraulic motor, a first sprocket, and a cutting chain. The rear end of the mounting frame is rotatably connected to the front end of the floating frame, and one side of the corresponding floating end floats up and down with it. There are two first sprockets, which are rotatably connected to the bottom end of the mounting frame and their rotation plane is arranged horizontally. The cutting chain is driven and connected to the two first sprockets. The fixed end of the hydraulic motor is fixedly connected to the mounting frame, and its power output end is driven and connected to the first sprocket.

[0013] Through the above technical solution, this utility model achieves bidirectional contouring of complex terrain by using floating frames arranged on both sides perpendicular to the direction of the power head's movement. The fixed end of the floating frame is fixedly connected to a floating connector and contacts the ground through a conforming ground wheel. When the conforming ground wheel floats up and down with the undulations of the ground, the floating frame adjusts vertically under the guidance of the floating connector. Simultaneously, a second conforming ground wheel is rotatably connected to the floating end of the floating frame. The second conforming ground wheel drives the floating end of the floating frame to move up and down under the action of ground undulations, enabling the floating frame to contour the ground at a certain angle to the side of the power head. The cutting mechanism is installed on the floating frame and moves with it, thereby cutting shrubs according to the terrain, achieving precise contouring of the longitudinal and lateral slopes of the ground, effectively improving the quality and efficiency of pruning operations.

[0014] Preferably, the hydraulic control mechanism includes a hydraulic rod and a balance valve. The hydraulic rod includes a cylinder and a piston rod. The inner cavity of the cylinder is arranged along the height direction of the power head, and its bottom end is fixedly connected to the power head. The inside of the cylinder is divided into upper and lower chambers along the direction of gravity by the piston inside. The chamber above the piston is the upper oil chamber, and the chamber below the piston is the lower oil chamber. The balance valve includes a valve body, a one-way throttling valve core, and a one-way valve core. The valve body has a one-way throttling channel and a one-way channel, and their corresponding ends are connected to the upper and lower oil chambers through pipelines. The one-way throttling valve core is installed in the one-way throttling channel to control the one-way throttling channel to flow slowly in one direction from the lower oil chamber to the upper oil chamber. The one-way valve core is installed in the one-way channel to control the one-way channel to flow in one direction from the upper oil chamber to the lower oil chamber. One end of the piston rod is fixed to the piston, and the other end passes through the top of the cylinder and is fixedly connected to the floating connector to passively receive force and move with the floating connector.

[0015] Preferably, it also includes a combing plate, which is fixedly connected to the floating end of the floating frame, and the front end of the combing plate is provided with multiple combing grooves.

[0016] Preferably, the cutting mechanism further includes a reeling assembly, which includes a second sprocket, a reeling chain, and reeling columns. The second sprocket is rotatably connected to the top of the mounting frame. There are two second sprockets rotatably connected to the top of the mounting frame, and their rotation plane is arranged horizontally. The reeling chain is sleeved on the outer periphery of the two second sprockets. There are multiple reeling columns, which are evenly arrayed along the outer periphery of the reeling chain.

[0017] Preferably, the number of floating frame, conformal ground wheel, cutting mechanism and combing plate is two sets, and they are symmetrically distributed about the center line of the power head.

[0018] Preferably, it also includes a guide plate, which is arranged along the front-rear direction of the power head and located between the two combing plates. The rear end of the guide plate is fixedly connected to the floating connector, and the front end of the guide plate is fixedly connected to a guide triangle plate.

[0019] Preferably, the width of the guide triangle plate along the side of the power head is greater than the interval between the two comb plates.

[0020] Preferably, there are two guide plates, which are arranged at intervals along the height direction of the power head.

[0021] Preferably, it also includes a support rod, which is arranged laterally along the power head and fixedly connected to the upper surface of the guide strip plate located above.

[0022] Preferably, there are two support rods, which are symmetrically distributed about the centerline of the power head.

[0023] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a floating contour-following coppicing machine, which has the following beneficial effects: By setting up components such as a power head, hydraulic control mechanism, floating connector, floating frame, conforming ground wheel one, conforming ground wheel two, and cutting mechanism, the coppicing machine can adapt to complex terrain. The fixed end of the floating frame is firmly connected to the floating connector and contacts the ground through conforming ground wheel one, realizing vertical contour-following adjustment; at the same time, the floating end of the floating frame is rotatably connected to conforming ground wheel two, so that the floating frame can contour the ground at a certain angle to the side of the power head. The cutting mechanism is installed on the floating frame and moves with the floating frame, thereby cutting shrubs according to the terrain, effectively improving the quality and efficiency of coppicing operations, and solving the problems that traditional coppicing machines are difficult to adapt to undulating land, uneven crop residue height, and changes in lateral terrain angle.

The first one-way sequence valve 26 is a high-pressure valve. When the hydraulic oil flows in reverse, the pressure of the first one-way sequence valve 26 reaches the pressure critical point. The hydraulic oil flowing in the reverse direction will overflow into the hydraulic oil tank 20 through its internal high-pressure relief valve. The second one-way sequence valve 27 is a low-pressure valve. When the pressure of the hydraulic oil flowing in the reverse direction reaches the second pressure critical point, the hydraulic oil flowing in the reverse direction will overflow into the hydraulic oil tank 20 through its internal low-pressure relief valve. The circulation pipeline between the upper oil chamber and the lower oil chamber is selectively connected to the first one-way sequence valve 26 and the second one-way sequence valve 27 through the two-position three-way valve 24.

The front end of the combing plate 6 has multiple combing grooves. During the pruning process, the combing plate 6 can separate the shrubs, allowing the cutting mechanism 5 to cut the shrubs more precisely, avoiding interference between the shrubs during cutting, and improving cutting quality and efficiency. At the same time, the design of the combing grooves can guide the direction of the shrubs, making the cut shrubs more uniform and facilitating subsequent collection and processing.

[0083] The three-position four-way valve 204 has three positions: a first position (b2045), a second position (b2046), and a third position (b2047). It also has four ports: a first port (b2041), a second port (b2042), a third port (b2043), and a fourth port (b2044).

[0086] Specifically, it also includes an equal flow divider valve 28, which includes an input port 281 and two output ports 282 with equal flow rates. The input port 281 is connected to the fourth interface b2044 through a pipeline, and the two output ports 282 are respectively connected to the input ports of the two hydraulic motors 52 through pipelines. The output ports of the two hydraulic motors 52 are connected to the input port of the hydraulic oil tank 20 through pipelines.

[0087] More specifically, it also includes three-position four-way valves 3205 and 4206. The three-position four-way valve 3205 has three positions: a first position c2055, a second position c2056, and a third position c2057. It also has four interfaces: a first interface c2051, a second interface c2052, a third interface c2053, and a fourth interface c2054. When in the first position c2055, the first interface c2051 and the second interface c2052 are connected, and the third interface c2053 and the fourth interface c2054 are connected. When in the second position c2056, the first interface c2051 and the third interface c2053 are connected, and the second interface c2052 and the fourth interface c2054 are connected. When in the third position c2057, the first interface c2051 and the fourth interface c2054 are connected, and the second interface c2052 and the third interface c2053 are connected.

It also has four ports: a first port d2061, a second port d2062, a third port d2063, and a fourth port d2064. When in the first position d2065, the first port d2061 and the second port d2062 are connected, and the third port d2063 and the fourth port d2064 are connected.

[0090] More specifically, when the three-position four-way valve 3205 and the three-position four-way valve 4206 are in the first position c2055 and the first position d2065 respectively, the two hydraulic motors 52 are in a stationary state. When the three-position four-way valve 3205 and the three-position four-way valve 4206 are in the second position c2056 and the second position d2066 respectively, the two hydraulic motors 52 are in a forward rotation state.

[0091] See appendix Figure 10 It also includes a guide plate 7, which is arranged along the front-rear direction of the power head 1 and located between the two combing plates 6. The rear end of the guide plate 7 is fixedly connected to the floating connector 3, and the front end of the guide plate 7 is fixedly connected to a guide triangle plate. Thus, the guide plate 7 blocks the opening between the two combing plates 6, preventing shrubs from entering the gap between the two combing plates 6.

[0092] In some other embodiments, the width of the guide triangle along the side of the power head 1 is greater than the interval between the two combing plates 6.

[0093] In some specific embodiments, there are two guide plates 7, which are arranged at intervals along the height direction of the power head 1.

[0094] In one embodiment, a support rod 8 is also included, which is arranged laterally along the power head 1 and fixedly connected to the upper surface of the guide strip 7 located above. Thus, the support rod 8 supports the stems cut from taller shrubs, preventing them from tipping over the power head 1.

[0095] In one embodiment, there are two support rods 8, which are symmetrically distributed about the centerline of the power head 1.

[0096] Specifically, the opposite ends of the two support rods 8 are bent toward the front of the power head 1.

[0097] In this embodiment, a controller is also included, which is electrically connected to a two-position three-way valve 24, a hydraulic pump 201, a three-position four-way valve 1 203, a three-position four-way valve 2 204, a three-position four-way valve 3 205, and a three-position four-way valve 4 206.

[0098] The specific principle and usage method of the floating contour coping machine provided in this embodiment are as follows:

[0099] Work status:

[0100] 1. The controller controls the two-position three-way valve 24 to switch to position one 244, and the interface one 241 is connected to the interface three 243. The second one-way sequence valve 27 is connected to the circulation pipeline between the upper oil chamber and the lower oil chamber.

[0101] 2. Control the three-position four-way valve 1 203 to switch to the first position a2035, the three-position four-way valve 2 204 to switch to the first position b2045, the three-position four-way valve 3 205 to switch to the second position c2056, and the three-position four-way valve 4 206 to switch to the second position d2066 via the controller;

[0102] 3. The hydraulic pump 201 is controlled by the controller. The hydraulic pump 201 pumps hydraulic oil from the hydraulic oil tank 20 through the three-position four-way valve 1 203 and the three-position four-way valve 204, then through the equal flow divider valve 28, and then through the two output ports 282 of the equal flow divider valve 28, respectively through the third interface c2053 of the three-position four-way valve 3 205 and the third interface d2063 of the three-position four-way valve 4 206, into the two hydraulic motors 52, driving the two hydraulic motors 52 to rotate. The rotation of the hydraulic motors 52 brings... The drive shaft 584 and the sprocket 53 fixedly connected to the drive shaft 584 rotate, which in turn drives the sprocket 53 fixedly connected to the drive shaft 585 to rotate through the cutting chain 54, which in turn drives the drive shaft 585 to rotate. The power of the drive shaft 585 to rotate is reduced by the reducer 56 and then drives the drive shaft 586 to rotate. The rotation of the drive shaft 586 drives the sprocket 551 fixedly connected to the drive shaft 586 to rotate. The rotation of the sprocket 551 drives the reeling chain 552 to rotate.

[0103] 4. The hydraulic oil flows out from the fourth port c2054 of the three-position four-way valve 205 and the fourth port d2064 of the three-position four-way valve 206 via two hydraulic pumps 201, and then flows back into the hydraulic oil tank 20.

[0104] 5. When the conformal wheel 42 encounters a low position, the connecting plate 92 descends, and the oil in the lower oil chamber flows into the upper oil chamber. The hydraulic oil in the lower oil chamber enters the second one-way sequence valve 27 via the two-position three-way valve 24. Since the flow direction of the second one-way sequence valve 27 is one-way flow from the upper oil chamber to the lower oil chamber, the hydraulic oil flowing into the second one-way sequence valve 27 will flow into the hydraulic oil tank 20 through the overflow valve in the second one-way sequence valve 27. At this time, since no hydraulic oil flows into the upper oil chamber, a negative pressure is formed. Since a check valve 23 is connected to the connecting pipeline between the upper oil chamber and the second one-way sequence valve 27, which allows hydraulic oil to flow into the circulation pipeline from the hydraulic oil tank 20 in one direction, the hydraulic oil flows into the upper oil chamber through the check valve 23 and the one-way throttle valve core 222 in the balance valve 22. During this process, the flow of hydraulic oil is hindered by the overflow valve in the second one-way sequence valve 27 and the one-way throttle valve core 222, thereby buffering the descent of the connecting plate 92 and the components mounted on the connecting plate 92.

[0105] 6. When the conforming wheel 42 encounters a high position, the connecting plate 92 rises, and the oil in the upper oil chamber flows into the lower oil chamber. The hydraulic oil in the upper oil chamber flows into the lower oil chamber through the one-way valve core 223 in the balance valve 22 and the second one-way sequence valve 27 in sequence. This completes the conforming of the conforming wheel 42 along the ground in the forward direction.

[0106] 7. When the power head 1 moves forward and encounters an inclined ground at an angle to the side of the power head 1, the conforming ground wheel 43 transmits the undulation of the ground to the second vertical rod 482, thereby causing the mounting frame 51 to swing along the front-back direction of the power head 1 as the axis, and in turn causing the cutting chain 54 and the reeling assembly 55 mounted on the mounting frame 51 to swing with the undulation of the ground, thus completing the conformation along the ground at a certain angle to the side of the power head 1.

[0107] 8. During the forward movement of the power head 1, the shrubs are cut off by the cutting chain 54, and the cut shrubs are guided to both sides of the power head 1 by the reeling assembly 55.

[0108] Non-working status:

[0109] 1. The controller controls the three-position four-way valve 205 to switch to the first position c2055, and the three-position four-way valve 206 to switch to the first position d2065, and the hydraulic motor 52 stops rotating;

[0110] 2. Adjust the height of the connecting plate 92 so that the conformal wheel 42 leaves the ground. When the three-position four-way valve 203 and the three-position four-way valve 204 are adjusted to the second position a2036 and the second position b2046, turn on the hydraulic pump 201. The hydraulic oil rushes into the lower oil chamber, and the connecting plate 92 rises. When the three-position four-way valve 203 and the three-position four-way valve 204 are adjusted to the third position a2037 and the third position b2047, turn on the hydraulic pump 201. The hydraulic oil rushes into the upper oil chamber, and the connecting plate 92 descends.

[0111] 3. After adjusting the connecting plate 92 to a suitable height, the controller controls the three-position four-way valve 1 203 and the three-position four-way valve 204 to adjust to the first position a2035 and the first position b2045, respectively. At the same time, the two-position three-way valve 24 is switched to position 245. The first one-way sequence valve 26, which is a high-pressure valve, counteracts the gravity of the connecting plate 92 and the components mounted on the connecting plate 92, keeping the connecting plate 92 in a suspended state.

[0112] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
