Description

Technical Field

[0001] This invention relates to the field of desert soil treatment, and in particular to a mobile desert soil treatment machine with a front-high and rear-low atomizing roller. Background Technology

[0002] Chinese patent document CN 118162456 A discloses a mobile desert soil treatment machine, which includes a frame, a walking system, and a desert soil atomization system. The desert soil atomization system includes an atomization chamber plate, two atomization rollers, and a roller drive device. The atomization chamber plate forms an atomization chamber with an opening at the bottom. The atomization rollers are rotatably mounted on the frame. Each atomization roller includes atomization fins extending radially outward. In the direction of rotation, the atomization fins of the front and rear atomization rollers are staggered. Thus, during the movement of the desert soil treatment machine, the atomization rollers can be positioned below the surface of the desert soil to be treated and rotate, using the atomization fins to bring the soil into the atomization chamber, atomizing the surface soil. This provides a prerequisite for the atomization of the soil conditioner and the surface soil, achieving surface treatment of the desert soil and forming a protective layer on the desert surface, effectively passivating the desert surface.

[0003] The patent document relates to a patent application made by the inventor of this patent application. In actual application of the above-mentioned mobile desert soil treatment machine, smaller stones and other harder lumps in the soil will remain in the atomization chamber and continuously collide with the atomization chamber plate and atomization rollers. This not only affects the atomization effect of the atomization rollers, but the continuous impact may also puncture the atomization chamber plate, causing damage to the atomization chamber plate and even creating safety hazards.

[0004] How to avoid or reduce the above problems and improve the processing efficiency and safety of mobile desert soil treatment machines are issues that need to be further improved or solved. Summary of the Invention

[0005] The purpose of this invention is to provide a control method for a mobile desert soil treatment machine, which enables the mobile desert soil treatment machine to operate with higher processing efficiency and safety.

[0006] Accordingly, the present invention also provides a mobile desert soil treatment machine that can implement the above-mentioned control method to improve treatment efficiency and safety.

[0007] The present invention provides a control method for a mobile desert soil treatment machine, wherein the mobile desert soil treatment machine includes a frame, a walking system, and a desert soil atomization system; the walking system is mounted on the frame; the desert soil atomization system includes an atomization chamber plate, a front atomization roller, and a rear atomization roller; the front atomization roller and the rear atomization roller are rotatably mounted on the frame in a front-to-back direction and are disposed in an atomization chamber formed by the atomization chamber plate; during operation, the outer diameter linear velocity of the rear atomization roller is lower than that of the front atomization roller to reduce the retention of hard lumps in the atomization chamber plate.

[0008] During atomization, the relatively rotating front and rear atomizing rollers bring stones or other hard objects from the atomization chamber into the atomization mixing space between the inner wall of the atomization chamber and the upper part of the atomizing rollers, where they remain. Because the outer diameter linear velocity of the rear atomizing roller is lower than that of the front atomizing roller, the collision frequency between the rear atomizing roller and the hard object is less than that between the front atomizing roller and the hard object. This makes it easier for the hard object to move rearward (above the rear atomizing roller), thus promoting its fall back behind the rear atomizing roller. This reduces the retention of hard objects in the atomization mixing space, improves the atomization mixing effect, and reduces collisions between hard objects and the atomization chamber walls and atomizing rollers, minimizing component damage and safety hazards.

[0009] In an optional technical solution, the front and rear atomizing rollers are identical (e.g., of the same size). During operation, the outer diameter linear velocity of the rear atomizing roller is lower than that of the front atomizing roller. Specifically, during operation, the rotational speed of the rear atomizing roller is reduced, or the rotational speed of the front atomizing roller is increased. Since the front and rear atomizing rollers are identical and have the same outer diameter, the lower rotational speed of the rear atomizing roller results in a lower outer diameter linear velocity, thus reducing the retention of hard lumps in the atomizing chamber. This improves the adaptability of the mobile desert soil treatment machine.

[0010] In an optional technical solution, the outer diameter of the front atomizing roller can be smaller than the outer diameter of the rear atomizing roller. This allows the linear velocity of the rear atomizing roller's outer diameter to be lower than that of the front atomizing roller, except when the rotational speeds of the front and rear atomizing rollers are equal.

[0011] In a further technical solution, the axis of the front atomizing roller is higher than the axis of the rear atomizing roller, or the top edge of the front atomizing roller is not lower than the top edge of the rear atomizing roller, thereby facilitating the backward movement and guidance of the hard block.

[0012] In a preferred embodiment, the rotational speed of the rear atomizing roller is lower than that of the front atomizing roller; specifically, the rotational speed of the rear atomizing roller is 70%-82% of that of the front atomizing roller.

[0013] The mobile desert soil treatment machine provided by this invention includes a frame, a walking system, and a desert soil atomization system; the walking system is mounted on the frame; the desert soil atomization system includes an atomization chamber plate, a front atomization roller, and a rear atomization roller; the front and rear atomization rollers are rotatably mounted on the frame and are arranged in the atomization chamber formed by the atomization chamber plate in the front-to-back direction; the front and rear atomization rollers are driven to rotate by a first roller drive device and a second roller drive device, respectively;

[0014] The mobile desert soil treatment machine also includes a speed difference adjustment system, which includes a collision detector and a controller. The output terminal of the collision detector is connected to the signal terminal of the controller to output a collision intensity signal to the controller. The control terminal of the controller is connected to both the first roller drive device and the second roller drive device to control the first roller drive device and the second roller drive device according to the collision intensity signal generated by the collision detector, thereby controlling the rotational speed of the front atomizing roller and the rear atomizing roller.

[0015] In this way, during operation, the speed of the rear atomizing roller can be lower than that of the front atomizing roller, thereby reducing the retention of hard lumps in the atomizing chamber plate.

[0016] In a further technical solution, both the first roller drive device and the second roller drive device include a hydraulic control valve and a hydraulic motor. In a preferred technical solution, the control terminal of the controller is connected to the hydraulic control valves of both the first and second roller drive devices. This facilitates control of the atomizing roller's rotation speed via hydraulic components, thereby guiding the hard object back down more quickly.

[0017] In a further optional technical solution, the mobile desert soil treatment machine also includes an inner vibrating plate, which is installed on the inner wall of the atomizing chamber plate by a spring; the collision detector is a vibration detector for detecting the vibration of the inner vibrating plate.

[0018] In a preferred embodiment, the mobile desert soil treatment machine includes multiple inner vibrating plates; the speed difference adjustment system includes multiple collision detectors; each inner vibrating plate corresponds to at least one collision detector. This allows the rotational speed of the atomizing roller to be controlled according to a predetermined strategy, such as controlling the rotational speed based on the average vibration of the multiple inner vibrating plates or based on the maximum vibration frequency or intensity of the inner vibrating plates.

[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that in this document, directional terms are used with reference to the operational status of the mobile desert soil treatment machine.

[0026] For ease of description, this section describes the mobile desert soil treatment machine and its control method simultaneously, without providing a separate description of the control method. It is understood that the control method for the mobile desert soil treatment machine provided by this invention is not limited to the mobile desert soil treatment machine described in this section, but can also be implemented using mobile desert soil treatment machines with other structures.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 An external perspective view of a mobile desert soil treatment machine provided in an embodiment of the present invention; Figure 2 for Figure 1 The image shows a longitudinal sectional view of the mobile desert soil treatment machine. Figure 3 for Figure 1 The diagram shows the connection structure of the mobile desert soil treatment machine frame and related parts. This invention provides a mobile desert soil treatment machine including a frame 100, a walking system 200, and at least one desert soil atomization system 300.

[0028] The walking system 200 is mounted on the frame 100, which facilitates the movement of the desert soil treatment machine and improves processing efficiency. The walking system 200 can be a vehicle or mechanical movement system, a wheeled walking system, or a walking system of other structures. To adapt to the desert environment, in this embodiment, the walking system is a tracked walking system, including tracks located on both sides. The walking system can be self-powered and move independently; or it can be unpowered and towed by other equipment. In this embodiment, the walking system of the mobile desert soil treatment machine is self-powered and can move independently.

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, the mobile desert soil treatment machine includes three desert soil atomization systems 300 arranged sequentially from front to back. Each desert soil atomization system 300 includes an atomization chamber plate, two atomization rollers 320, and a roller drive device; the atomization chamber plate forms an atomization chamber with an opening at the bottom. In each atomization chamber, the front and rear atomization rollers are arranged in pairs, denoted as 320a and 320b respectively; in special cases, more atomization rollers may be provided. Each atomization roller includes atomization fins extending radially outward; in the direction of rotation axis extension, the atomization fins of the front and rear atomization rollers are staggered to bring the soil to be treated into the atomization chamber during relative rotation, thereby achieving soil atomization.

[0030] The desert soil atomization system 300 is also equipped with a roller drive device, which can be mounted on the frame 100 to drive the front atomizing roller 320a and the rear atomizing roller 320b to rotate. In this embodiment, each atomizing roller is equipped with an individual roller drive device to control the rotation speed of the atomizing roller separately, ensuring the power supply to the atomizing roller and facilitating the control of the rotation speed of the atomizing roller.

[0031] In this way, during the movement of the desert soil treatment machine, the outer diameter of the atomizing fins of the front atomizing roller 320a and the rear atomizing roller 320b can be positioned appropriately below the surface of the desert soil to be treated, and they can rotate relative to each other at an appropriate speed. The atomizing fins of the atomizing rollers carry the soil to be treated into the atomization chamber. The rotation at an appropriate speed can cause the surface soil to be atomized, thus providing a basis for the atomization and mixing of the soil conditioner with the surface soil. This achieves surface treatment of the desert soil, forming a protective layer on the desert surface, effectively passivating the desert surface. In one embodiment, the front atomizing roller 320a and the rear atomizing roller 320b can be positioned approximately 200mm below the surface of the desert soil to be treated, allowing passivation treatment of the soil within a 200mm radius of the desert surface.

[0032] Figure 4 for Figure 1The diagram shows the working principle of the desert soil atomization system of the mobile desert soil treatment machine. In one embodiment of the invention, in the control method of the mobile desert soil treatment machine, during operation, the rotational speed of the rear atomizing roller 320b is lower than that of the front atomizing roller 320a to reduce the retention of hard lumps in the atomization chamber plate. Thus, during atomization, the relatively rotating front and rear atomizing rollers bring stones or other hard lumps into the atomization mixing space between the inner wall of the atomization chamber and the upper part of the atomizing rollers, where they remain. Because the rear atomizing roller rotates at a lower speed than the front atomizing roller, the collision frequency between the rear atomizing roller and the hard object is less than that between the front atomizing roller and the hard object. This makes it easier for the hard object to move rearward (above the rear atomizing roller), thus promoting its fall back behind the rear atomizing roller. This reduces the retention of the hard object in the atomization mixing space, improves the atomization mixing effect, and reduces collisions between the hard object and the atomization chamber wall and atomizing roller, thereby reducing component damage and safety hazards.

[0033] In the preferred technical solution, the front atomizing roller 320a and the rear atomizing roller 320b are identical. During operation, the outer diameter linear velocity of the rear atomizing roller 320b is lower than that of the front atomizing roller 320a. Specifically, during operation, the rotational speed of the rear atomizing roller 320b is reduced, or the rotational speed of the front atomizing roller 320a is increased. Since the front and rear atomizing rollers are identical and have the same outer diameter, the lower rotational speed of the rear atomizing roller results in a lower outer diameter linear velocity, thus reducing the retention of hard lumps in the atomizing chamber. This improves the adaptability of the mobile desert soil treatment machine. In one embodiment, the outer edge curvature radius (outer diameter) of the front atomizing roller 320a and the rear atomizing roller 320b is 375 mm. The rotational speed of the front atomizing roller 320a is 180-193 RPM, and the rotational speed of the rear atomizing roller 320b is 100-150 RPM. The difference in height between the front and rear rollers makes the parabolic curve of the rear atomizing roller 320b close to the semi-circular curve of the top of the atomizing chamber. This ensures that hard lumps are less trapped in the atomizing mixing space, thus improving the atomization mixing effect. Furthermore, the identical design of the front and rear atomizing rollers 320a and 320b enhances the adaptability of the mobile desert soil treatment machine.

[0034] In the mobile desert soil treatment machine of the embodiment, both the front atomizing roller 320a and the rear atomizing roller 320b include a central shaft 321 and atomizing fins 322 extending radially outward from the surface of the central shaft 321; the rotation axes of the front atomizing roller 320a and the rear atomizing roller 320b are laterally parallel; in the direction of extension of the rotation axes, the atomizing fins 322 of the front atomizing roller 320a and the atomizing fins 322 of the rear atomizing roller 320b are staggered, and the... The atomizing fins 322 of the front atomizing roller 320a and the rear atomizing roller 320b overlap in their projections in a plane perpendicular to the rotation axis. This ensures that the front and rear atomizing rollers 320a and 320b maintain a suitable degree of overlap, meaning that even when there is a corresponding height difference between the top of the rear atomizing roller 320b and the top of the front atomizing roller 320a, the effective rotational sections of the front and rear atomizing rollers 320a maintain a suitable overlap. The rotation axis of the front atomizing roller 320a and the rotation axis of the rear atomizing roller 320b can be at the same or different heights.

[0035] In a preferred embodiment, the mobile desert soil treatment machine further includes a lifting support 110 that is rotatably mounted on the frame 100; the front atomizing roller 320a or the rear atomizing roller 320b is rotatably mounted on the lifting support 110, meaning one of the front atomizing roller 320a or the rear atomizing roller 320b is rotatably mounted on the lifting support 110, while the other remains fixed. By adjusting the height of the front atomizing roller 320a or the rear atomizing roller 320b, the height difference between the top of the rear atomizing roller 320b and the top of the front atomizing roller 320a can be maintained within an appropriate range; and the height difference between the front atomizing roller 320a or the rear atomizing roller 320b can be increased or decreased according to the actual soil layer being treated, to form rolling surfaces with different inclinations, allowing the hard lumps S trapped in the atomization mixing space by the front atomizing roller 320a and the rear atomizing roller 320b to be guided back down quickly and smoothly. In one embodiment, the rotational speed of the rear atomizing roller 320b can be 70%-82% of the rotational speed of the front atomizing roller 320a.

[0036] Please combine Figure 3 ,refer to Figure 5 , Figure 5 for Figure 4A block diagram of the speed difference adjustment system of a mobile desert soil treatment machine. The mobile desert soil treatment machine also includes a speed difference adjustment system, which includes a collision detector 410 and a controller 420. The output terminal of the collision detector 410 is connected to the signal terminal of the controller 420 to output a collision intensity signal to the controller 420. The signal connection can be wired or wireless. The control terminal of the controller 420 is connected to both the first roller drive device and the second roller drive device to control the first roller drive device and the second roller drive device according to the collision intensity signal generated by the collision detector 410, thereby controlling the rotational speed of the front atomizing roller 320a and the rear atomizing roller 320b.

[0037] In one embodiment, the front atomizing roller 320a and the rear atomizing roller 320b are driven to rotate by a first roller drive device and a second roller drive device, respectively; that is, the drive devices for the front atomizing roller 320a and the rear atomizing roller 320b are independent of each other for easy separate control. Both the first roller drive device and the second roller drive device include a hydraulic control valve 510 and a hydraulic motor 520. A hydraulic control valve 510 is connected between a hydraulic motor 520 and a hydraulic source, thereby adjusting the output speed of the hydraulic motor 520 by regulating the hydraulic control valve 510. The hydraulic control valve 510 can be an electrically controlled valve for quantitative control via an electrical signal. The control terminal of the controller 420 is connected to the electrical control terminals of the hydraulic control valve 510 of both the first and second roller drive devices.

[0038] Thus, when there are many or large hard objects causing intense collisions (vibration frequency, sound intensity, or collision force), and the collision detector detects that the collision intensity exceeds a predetermined threshold, the controller 420 can send a control signal to the hydraulic control valve 510 to control the rotation speed of the hydraulic motor 520. This causes the rotation speed of the front atomizing roller 320a to be greater than that of the rear atomizing roller 320b, thereby promoting the hard objects to fall back from behind the rear atomizing roller. This reduces the retention of hard objects in the atomization mixing space, improves the atomization mixing effect, and reduces collisions between hard objects and the atomization chamber wall and atomizing rollers, thus reducing component damage and safety hazards.

[0039] The collision detector can be a vibration detection device, a sound detection device, or a force detection device, etc., to determine the collision intensity through vibration, sound, or collision force.

[0040] See again Figure 4To facilitate vibration intensity detection, the mobile desert soil treatment machine may further include an inner vibrating plate 430, which is mounted on the inner wall of the atomizing chamber plate 310 via springs. The collision detector 410 is a vibration detector for detecting the vibration of the inner vibrating plate 430. Multiple inner vibrating plates 430 may also be included. The position difference adjustment system may include multiple collision detectors 410, with each inner vibrating plate 430 corresponding to at least one collision detector 410. This allows for control of the atomizing roller's rotational speed according to a predetermined strategy, such as controlling the rotational speed based on the average vibration of multiple inner vibrating plates 430 or based on the maximum vibration frequency or intensity of the inner vibrating plates 430, or reducing the rotational speed of the rear atomizing roller 320b, or increasing the rotational speed of the front atomizing roller 320a.

[0041] In another embodiment, the outer diameter of the front atomizing roller 320a can be smaller than the outer diameter of the rear atomizing roller 320b. This allows the outer diameter linear velocity of the rear atomizing roller 320b to be lower than that of the front atomizing roller 320a, while maintaining the rotational speeds of the front and rear atomizing rollers 320b at the same rate. Furthermore, this reduces the collision frequency between the rear atomizing roller and the hard object compared to the front atomizing roller, making it easier for the hard object to move rearward (above the rear atomizing roller). This facilitates the hard object's fall back from behind the rear atomizing roller, reducing its retention in the atomization mixing space, improving the atomization mixing effect, and minimizing collisions between the hard object and the atomization chamber wall and atomizing rollers, thus reducing component damage and safety hazards. According to the applicant's test results, the outer diameter linear velocity of the front atomizing roller 320a can be around 7.6 m / s, and the outer diameter linear velocity of the rear atomizing roller 320b can be around 90%-95% of that of the front atomizing roller 320a. This promotes the falling of hard lumps from behind the rear atomizing roller, thereby reducing the retention of hard lumps in the atomization mixing space and improving the atomization mixing effect of the atomization mixing space.

[0042] like Figure 6The diagram shows the working principle of another mobile desert soil treatment machine's desert soil atomization system. The axis of the front atomizing roller 320a can be higher than the axis of the rear atomizing roller 320b, or the top edge of the front atomizing roller 320a can be at the same height as the top edge of the rear atomizing roller 320b, thus facilitating the backward movement and guidance of hard lumps. Alternatively, the top edge of the front atomizing roller 320a can be no lower than the top edge of the rear atomizing roller 320b, again facilitating the backward movement and guidance of hard lumps. Of course, the contact between the front atomizing roller 320a and the desert soil to be treated also needs to be considered, ensuring that the front and rear atomizing rollers 320a and 320b have suitable dimensions to guarantee the treatment of the desert soil surface and achieve surface passivation treatment.
