Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a rotary tillage test platform for hilly and mountainous slopes. Background Technology

[0002] The farmland in hilly and mountainous areas is fragmented, irregular, rugged, and sloping. This uneven terrain makes traditional rotary tillers unsuitable for conducting multi-factor, multi-level experiments due to inconsistent tillage depth, strong machine vibration, and high power consumption on slopes of varying angles. Therefore, there is an urgent need for an experimental platform for rotary tillage that can be adjusted to different angles, specifically for hilly and mountainous terrain. Developing such a platform would provide essential experimental data to support the stability and climbing ability of rotary tillage on slopes.

[0003] Publication (Announcement) No.: CN215011391U discloses a "Soil Trough Platform for Studying the Interaction Mechanism of Rotary Tiller Blades and Slope Soil," which includes: a support frame, a worm gear tillage depth adjustment device, a rotary tillage device, a soil trough, a soil trough inclination angle adjustment device, and a soil trough moving device. The soil trough inclination angle adjustment device simulates different slope angles during rotary tillage operations; the worm gear tillage depth adjustment device adjusts the tillage depth; the soil trough moving device simulates the forward movement of the rotary tiller blade; and the rotary tillage device realizes the rotational movement of the rotary tiller blade.

[0004] The problem it has is:

[0005] Its soil box moves on the guide rail and is driven by chain. The transmission distance is relatively large, and the lower end of the chain drive is close to the ground. The chain is prone to contact with the ground and the wear is relatively large. Its movement mode is that the rotary tiller blades are stationary relative to the ground, while the soil trough moves on the guide rail, which is inconsistent with the traditional rotary tillage operation mode. Its soil trough moves by using guide rail, which is relatively troublesome to disassemble and assemble. Utility Model Content

[0006] To address the problems of unstable tillage depth, strong machine vibration, and high power consumption in hilly and mountainous terrain with varying slope angles, which hinder multi-factor and multi-level assessments, this invention provides a hilly and mountainous slope rotary tillage test platform. This platform simulates rotary tillage on hilly and mountainous slopes, offering advantages such as the ability to simulate slope angles from 0° to 20°, mimic small rotary tillers, adjust the tilt angle of the tillage blades, and maintain good operational stability. It provides essential experimental support for assessing the stability of rotary tillage on hilly and mountainous slopes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution.

[0008] A hilly and mountainous slope rotary tillage test platform includes a slope inclination simulation mechanism, a cutting tool workbench, a rotary tillage moving mechanism, and a gantry frame. The slope inclination simulation mechanism includes a soil box, a frame, a frame trolley, wheels, a hydraulic oil tank, and jacks. Four wheels are installed on the bottom of the frame trolley for moving the test platform. The jacks are hinged to the crossbeam of the frame trolley via lugs. The hydraulic oil tank is connected to one end of the frame trolley via screws. The top of the jacks is hinged to one side of the frame via pins, and the other side of the frame is hinged to the frame trolley via pins. A soil box is connected to the frame. The jacks drive the frame to rotate around the hinge point between the frame trolley and the frame trolley, changing the inclination angle of the frame, thereby changing the inclination angle of the soil box.

[0009] The aforementioned blade worktable includes a rotary tiller motor, a rotary tiller tilt plate, a rotary tiller lifting plate, rotary tiller blades, a rotary tiller blade shaft, a rotary tiller reducer, and an electric push rod. The rotary tiller blades are connected and mounted on the rotary tiller blade shaft. The rotary tiller blade shaft and the rotary tiller reducer are connected. The rotary tiller motor is connected and drives the rotary tiller reducer to rotate the rotary tiller blade shaft. The rotary tiller motor is connected and mounted on the rotary tiller reducer. One side of the rotary tiller tilt plate is hinged to the electric push rod, and the other side of the rotary tiller tilt plate is hinged to the rotary tiller lifting plate. The electric push rod pushes the rotary tiller tilt plate to rotate around the hinge point between it and the rotary tiller lifting plate to change the tilt angle of the rotary tiller tilt plate.

[0010] The rotary tillage moving mechanism includes a trolley motor, an electric trolley, a connecting plate, a screw lifting mechanism, and a screw lifting mechanism motor. The connecting plate is connected to the electric trolley, which is mounted on the crossbeam of the gantry frame. The trolley motor drives the electric trolley to move along the crossbeam of the gantry frame. The connecting plate is equipped with a screw lifting mechanism and a screw lifting mechanism motor. The screw lifting mechanism motor drives the screw lifting mechanism to work, and the working of the screw lifting mechanism drives the rotary tillage lifting plate to rise and fall.

[0011] The frame is made of angle steel, and the frame trolley is made of channel steel, both readily available materials that provide good support. The wheels are made of nylon, which is lightweight, wear-resistant, self-lubricating, and has a long service life at low temperatures.

[0012] An inclination sensor is connected to the end of the electric push rod and is used to detect different inclination angles. The inclination sensor is electrically connected to the control system, transmitting inclination signals. When the control system receives an inclination signal from the soil box, it controls the stroke of the electric push rod, causing the rotary tiller inclination plate to rotate at the corresponding inclination angle, making the inclination angle of the rotary tiller inclination plate the same as that of the soil box, thus matching the actual working conditions. When the electric trolley drives the blade worktable forward, it simulates the operation of a rotary tiller.

[0013] This technical solution utilizes an electric push rod to move the tool table, allowing for adjustment of its tilt angle. The tool table is also driven by an electric trolley, enabling movement along the crossbeam of the gantry frame. Furthermore, the tool table is raised and lowered by a screw lifting mechanism, thus avoiding various shortcomings and deficiencies of existing technologies. This results in a technical solution that can simulate slopes from 0° to 20°, mimic a small rotary tiller, achieve adjustable rotary tiller blade tilt angles, and demonstrates good operational stability, providing necessary experimental support for the stability of rotary tillage on hilly and mountainous slopes.

[0014] As a further improvement to this technical solution:

[0015] The side of the frame trolley that is hinged to the frame is set with an inclined surface, which narrows the top of the frame trolley.

[0016] The frame trolley narrows at the top of the hinge, allowing the frame and soil box to rotate better.

[0017] The jacks are arranged in two intervals.

[0018] Two jacks are set up to operate synchronously, providing power to drive the frame and soil box to change their tilt angle. The power is sufficient and the test stability is high.

[0019] The rotary tiller blades and the rotary tiller blade shaft are bolted together.

[0020] The rotary tiller blades are connected to the rotary tiller shaft using bolts, which facilitates the disassembly, maintenance, or replacement of the rotary tiller blades.

[0021] The device has two electric push rods, which are respectively located on both sides of the rotary tiller reducer. The bottom ends of the two electric push rods are hinged to the rotary tiller lifting plate, and the rotary tiller lifting plate is provided with a hinged connecting seat to connect the electric push rods.

[0022] With the above setup, the two electric push rods move synchronously to provide power and drive the rotary tillage tilt plate to change the tilt angle. The power is sufficient and the test stability is high.

[0023] The rotary tillage lifting plate has a connecting opening at its center, which is a through hole, and a rotary tillage tilting plate is connected above the connecting opening.

[0024] By setting up a connection opening, we can reduce the weight of the rotary tillage lifting plate, facilitate the connection of the electric push rod and provide sufficient space for its pushing action, and prevent the rotary tillage blades from colliding with the rotary tillage lifting plate when working at different tilt angles.

[0025] The screw lifting mechanism is equipped with a vertically arranged drive screw rod, which is driven to rotate by the screw lifting mechanism motor, and the drive screw rod is threadedly engaged with the rotary tillage lifting plate.

[0026] By setting a drive screw rod, which is threadedly engaged with the rotary tiller lifting plate, the rotation of the drive screw rod drives the rotary tiller lifting plate to rise and fall, thereby driving the tool table to rise and fall.

[0027] The rotary tillage lifting plate is rectangular, and screw holes are provided at all four corners of the rotary tillage lifting plate to engage with the threaded drive screw rod;

[0028] With the above setup, the rotary tiller lifting plate is synchronously driven by four drive screws at the four corners, providing sufficient power and high stability in the test. Figure 6 The diagram shown illustrates the principle of simulating a 20° slope on this test platform.

[0029] The working process of this embodiment is as follows:

[0030] The hydraulic tank acts as a jack, causing the jack to extend and rotate the frame and soil box to form a 20° tilt angle. The tilt angle sensor receives the tilt angle signal from the bottom, and the controller controls the electric push rod to drive the rotary tillage tilt plate to rotate around the longitudinal rotary tillage lifting plate to form a 20° tilt angle.

[0031] The working principle of this embodiment is as follows:

[0032] First: Slope angle simulation. The hydraulic tank acts as a jack, causing the jack to extend and drive the frame and soil box to rotate, thus forming an inclination angle.

[0033] Second: Rotary tillage tilt angle simulation, the electric push rod drives the rotary tillage tilt plate to rotate around the longitudinal rotary tillage lifting plate to form the tilt angle.

[0034] Third: Simulation of rotary tillage action. The rotary tillage motor acts on the rotary tillage reducer, which in turn acts on the rotary tillage blade shaft, thus driving the rotary tillage blades to rotate. Fourth: Simulation of rotary tillage lifting adjustment. The screw lifting mechanism and the rotary tillage lifting plate are connected. When the screw lifting mechanism starts to rotate, the rotary tillage lifting plate will adjust its height accordingly.

[0035] Fifth: Rotary tillage forward simulation, the motor of the trolley will drive the electric trolley forward, and the electric trolley will drive the tool table forward through the connecting plate. Attached Figure Description

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0044] See Figures 1-4 As can be seen, the hilly slope rotary tillage test platform of this utility model consists of a slope inclination angle simulation mechanism 1, a tool worktable 2, a rotary tillage moving mechanism 3, and a gantry frame 4; the structural description of each part is as follows:

[0045] See Figure 1 , Figure 2 As shown, the slope inclination simulation mechanism 1 includes a soil box 5, a frame 6, a frame trolley 7, wheels 8, a hydraulic oil tank 9, and a jack 10. Four wheels 8 are installed at the bottom of the frame trolley 7 for moving the test platform. The jack 10 is hinged to the crossbeam of the frame trolley 7 via lifting lugs. The hydraulic oil tank 9 is connected to one end of the frame trolley 7 via screws. The top of the jack 10 is hinged to one side of the frame 6 via a pin, and the other side of the frame 6 is hinged to the frame trolley 7 via a pin. The soil box 5 is connected to the frame 6. The jack 10 drives the frame 6 to rotate around its hinge point with the frame trolley 7, changing the inclination angle of the frame 6, thereby changing the inclination angle of the soil box 5.

[0046] See Figure 1 , Figure 3As shown, the blade workbench 2 includes a rotary tillage motor 11, a rotary tillage tilting plate 12, a rotary tillage lifting plate 13, a rotary tillage blade 14, a rotary tillage blade shaft 15, a rotary tillage reducer 16, and an electric push rod 17. The rotary tillage blade 14 is connected to the rotary tillage blade shaft 15. The rotary tillage blade shaft 15 is connected to the rotary tillage reducer 16. The rotary tillage motor 11 drives the rotary tillage reducer 16 to rotate the rotary tillage blade shaft 15. The rotary tillage motor 11 is connected to the rotary tillage reducer 16. One side of the rotary tillage tilting plate 12 is hinged to the electric push rod 17, and the other side of the rotary tillage tilting plate 12 is hinged to the rotary tillage lifting plate 13. The electric push rod 17 pushes the rotary tillage tilting plate 12 to rotate around the hinge point with the rotary tillage lifting plate 13 to change the tilt angle of the rotary tillage tilting plate 12.

[0047] See Figure 1 , Figure 4 As shown, the rotary tillage moving mechanism 3 includes a trolley motor 18, an electric trolley 19, a connecting plate 20, a screw lifting mechanism 21, and a screw lifting mechanism motor 22. The connecting plate 20 is connected to the electric trolley 19, which is mounted on the crossbeam of the gantry frame 4. The trolley motor 18 drives the electric trolley 19 to move along the crossbeam of the gantry frame 4. The connecting plate 20 is equipped with a screw lifting mechanism 21 and a screw lifting mechanism motor 22. The screw lifting mechanism motor 22 drives the screw lifting mechanism 21 to work, and the working of the screw lifting mechanism 21 drives the rotary tillage lifting plate 13 to rise and fall. The frame 6 is made of angle steel, and the frame trolley 7 is made of channel steel. The materials are readily available and have good support performance. The wheels 8 are made of nylon wheels, which have the advantages of being lightweight, wear-resistant, self-lubricating, having a long service life at low temperatures, and having a large load-bearing capacity.

[0048] The tilt sensor is connected to the end of the electric push rod and is used to detect different tilt angle data. The tilt sensor is electrically connected to the control system and sends tilt angle signals to the control system. When the control system receives the tilt angle signal from the soil box 5, the control system controls the stroke of the electric push rod 17 to make the rotary tillage tilt plate 12 rotate at the corresponding tilt angle so that the tilt plate 12 is the same as the tilt angle of the soil box 5, so as to match the actual working conditions.

[0049] When the electric sports car 18 drives the blade worktable 2 forward, it can simulate the operation process of a rotary tiller.

[0050] The cutting tool table 2 is pushed by the electric push rod 17, which can change its inclination angle; the cutting tool table 2 is driven by the electric trolley 19, which can move along the crossbeam of the gantry frame 4; the cutting tool table 2 is driven by the screw lifting mechanism 21, which can raise and lower; thus avoiding various shortcomings and deficiencies of the existing technology. Therefore, this technical solution has the advantages of simulating slope inclination angles from 0° to 20°, simulating a small rotary tiller, realizing the adjustment of the rotary tillage blade inclination angle, and good working stability, providing necessary experimental support for the stability of rotary tillage on hilly and mountainous slopes.

[0051] See Figure 1 , Figure 2 As shown, the side where the frame trolley 7 is hinged to the frame 6 is sloped, which narrows the top of the frame trolley 7. The narrowing of the top of the frame trolley 7 at the hinge allows the frame 6 and the soil box 5 to rotate more effectively.

[0052] See Figure 1 , Figure 2 As shown, two jacks 10 are arranged at intervals.

[0053] Two jacks 10 are set up to operate synchronously, providing power to drive the frame 6 and soil box 5 to change their tilt angle. The power is sufficient and the test stability is high.

[0054] The rotary tiller blades 14 and the rotary tiller shaft 15 are bolted together.

[0055] The rotary tiller blade 14 is connected to the rotary tiller shaft 15 by bolts, which facilitates the disassembly, maintenance or replacement of the rotary tiller blade 14.

[0056] See Figure 1 , Figure 3 As shown, there are two electric push rods 17, which are respectively arranged on both sides of the rotary tiller reducer 16. The bottom ends of the two electric push rods 17 are hinged to the rotary tiller lifting plate 13, and the rotary tiller lifting plate 13 is provided with a hinged connecting seat to connect the electric push rods 17. With the above arrangement, the two electric push rods 17 move synchronously, providing power to drive the rotary tiller tilting plate 12 to change the tilt angle. The power is sufficient and the test stability is high.

[0057] The rotary tillage lifting plate 13 has a connecting opening at its center, which is a through hole. A rotary tillage tilting plate 12 is connected above the connecting opening. This connecting opening serves three purposes: first, it reduces the weight of the rotary tillage lifting plate 13; second, it facilitates the connection of the electric push rod 17, providing ample space for its pushing action; and third, it prevents the rotary tillage blades from colliding with the rotary tillage lifting plate 13 when operating at different tilt angles. (See also...) Figure 1 , Figure 4 As shown, the screw lifting mechanism 21 is provided with a vertically arranged drive screw rod, which is driven to rotate by the screw lifting mechanism motor 22, and the drive screw rod is threadedly engaged with the rotary tillage lifting plate 13.

[0058] By setting a drive screw rod, and utilizing the threaded engagement between the drive screw rod and the rotary tillage lifting plate 13, the rotation of the drive screw rod drives the rotary tillage lifting plate 13 to rise and fall, thereby driving the tool worktable 2 to rise and fall.

[0059] The rotary tillage lifting plate 13 is rectangular, and screw holes are provided at all four corners of the rotary tillage lifting plate 13 to engage with the threaded drive screw rod.

[0060] With the above setup, the rotary tiller lifting plate 13 is synchronously driven by four drive screws at its four corners, providing sufficient power and high stability during testing. (See also...) Figure 6 The diagram shown illustrates the principle of simulating a 20° slope on this test platform.

[0061] The working process of this embodiment is as follows:

[0062] The hydraulic oil tank 9 acts on the jack 10, causing the jack 10 to extend and drive the frame 6 and soil box 5 to rotate, thus forming a 20° tilt angle. The tilt angle sensor receives the tilt angle signal from the bottom, and the controller controls the electric push rod 17 to drive the rotary tillage tilt plate 12 to rotate around the longitudinal rotary tillage lifting plate 13 to form a 20° tilt angle.

[0063] The working principle of this embodiment is as follows:

[0064] First: Slope angle simulation. The hydraulic oil tank 9 acts on the jack 10, causing the jack 10 to extend and drive the frame 6 and the soil box 5 to rotate, thus forming an inclination angle.

[0065] Second: Rotary tillage tilt angle simulation, the electric push rod 17 drives the rotary tillage tilt plate 12 to rotate around the longitudinal rotary tillage lifting plate 13 to form an tilt angle.

[0066] Third: Rotary tillage action simulation. The rotary tillage motor 11 acts on the rotary tillage reducer 16, and the rotary tillage reducer 16 acts on the rotary tillage blade shaft 15, thereby driving the rotary tillage blade 14 to rotate.

[0067] Fourth: Rotary tillage lifting adjustment simulation. The screw lifting mechanism 21 and the rotary tillage lifting plate 13 are connected. When the screw lifting mechanism 21 starts to rotate, the rotary tillage lifting plate 13 will adjust its height accordingly to the rotation of the screw lifting mechanism 21.

[0068] Fifth: Rotary tillage forward simulation, the operation of the trolley motor 18 will drive the electric trolley 19 forward, and the electric trolley 19 will drive the tool table 2 forward through the connecting plate 20.

[0069] The structure and working principle of this utility model have been described above with specific embodiments. This utility model is not limited to the above embodiments. Based on the above description, any modifications, equivalent substitutions and improvements made on the basis of the spirit and principles of this utility model should be included within the protection scope of this utility model.
