Abstract

The present invention discloses a mobile desert soil processing machine with an atomizing roller that is high in the front and low in the back. The mobile desert soil processing machine includes a frame, a walking system and a desert soil atomization system; the desert soil atomization system includes an atomizing bin plate, a front atomizing roller and a rear atomizing roller; the front atomizing roller and the rear atomizing roller are rotatably mounted on the frame in the front-to-back direction, and are arranged in pairs in the atomizing bin, and the top of the rear atomizing roller is lower than the top of the front atomizing roller. During the atomization process, the front atomizing roller and the rear atomizing roller bring the hard fast objects from the atomizing bin to the atomizing mixing space between the inner wall of the atomizing bin and the upper part of the atomizing roller, and retain them in the atomizing mixing space. Since the top of the rear atomizing roller is lower than the top of the front atomizing roller, a rolling surface inclined backwards is formed on the upper part of the atomizing roller; the inclined rolling surface can guide the retained hard fast objects backwards, thereby reducing the retention of the hard fast objects and improving the atomization mixing effect.

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, and further provides a prerequisite for the combination of the conditioner and the desert soil, achieving surface treatment of the desert soil and forming a protective layer on the desert surface, thus 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, lumpy objects in the soil will remain in the atomizing chamber plate and continuously collide with the atomizing chamber plate wall and atomizing rollers. This not only affects the atomization effect of the atomizing rollers, but the continuous impact may also puncture the atomizing chamber plate, causing damage to the atomizing 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 mobile desert soil treatment machine with a front-high and rear-low atomizing roller, which has higher treatment efficiency and safety.

[0006] To address this, the present invention provides a mobile desert soil treatment machine, comprising 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 in a front-to-back direction and are arranged in pairs within the atomization chamber, with the top of the rear atomization roller lower than the top of the front atomization roller. During atomization, the relatively rotating front and rear atomization rollers carry stones or other hard, lumpy objects from the atomization chamber into the atomization mixing space between the inner wall of the atomization chamber and the upper part of the atomization rollers, where they remain. Because the top of the rear atomizing roller is lower than the top of the front atomizing roller, a roughly backward-sloping "rolling surface" is formed on the upper part of the atomizing roller. The inclined rolling surface can guide the stuck hard objects backward and let them fall back from behind the rear atomizing roller, thereby reducing the retention of hard objects in the atomization mixing space, improving the atomization mixing effect of the atomization mixing space, and reducing the collision of hard objects with the atomization chamber plate and atomizing roller, reducing component damage and safety hazards.

[0007] In the preferred technical solution, the front and rear atomizing rollers are identical. This allows for the interchangeability of the front and rear atomizing rollers, and through periodic interchange, even wear on the front and rear atomizing rollers is achieved, improving the maintainability of the mobile desert soil treatment machine.

[0008] In a preferred embodiment, the rotation axis of the rear atomizing roller is lower than the rotation axis of the front atomizing roller, thereby making the top of the rear atomizing roller lower than the top of the front atomizing roller.

[0009] In an optional technical solution, the height difference between the top of the rear atomizing roller and the top of the front atomizing roller is greater than one-tenth of the diameter of the rear atomizing roller. Simultaneously, the height difference between the top of the rear atomizing roller and the top of the front atomizing roller is less than two-tenths of the diameter of the rear atomizing roller.

[0010] In a preferred embodiment, both the front and rear atomizing rollers include a central shaft and atomizing fins extending radially outward from the surface of the central shaft. The rotation axes of the front and rear atomizing rollers are laterally parallel. In the direction of rotation axis extension, the atomizing fins of the front and rear atomizing rollers are staggered, and the projections of the atomizing fins of the front and rear atomizing rollers in a plane perpendicular to the rotation axis overlap, thus ensuring that the front and rear atomizing rollers maintain an appropriate degree of overlap.

[0011] In a preferred embodiment of the present invention, the mobile desert soil treatment machine may further include a lifting support that is rotatably mounted on the frame; the front atomizing roller or the rear atomizing roller is rotatably mounted on the lifting support, that is, one of the front atomizing roller or the rear atomizing roller is rotatably mounted on the lifting support, while the other can remain fixed. By adjusting the height of the front atomizing roller or the rear atomizing roller, the height difference between the top of the rear atomizing roller and the top of the front atomizing roller can be maintained within an appropriate range; and according to the actual soil layer being treated, the height difference between the front atomizing roller or the rear atomizing roller can be increased or decreased to form rolling surfaces with different inclinations, so that hard, lumpy objects entrained in the atomization mixing space by the front and rear atomizing rollers can be guided back quickly and smoothly.

[0012] In a further technical solution, the mobile desert soil treatment machine also includes a position difference adjustment system, which includes a lifting hydraulic component, a collision detector, a lifting electric control valve, and a controller; the lifting hydraulic component drives the lifting support to rise and fall relative to the frame; the lifting electric control valve is connected between the lifting hydraulic component and the hydraulic oil source; the collision detector is used to detect the collision state experienced by the inner wall of the atomizing chamber plate and generate a collision intensity signal;

[0013] 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 the signal terminal of the lifting solenoid valve to control the lifting solenoid valve according to the collision intensity signal generated by the collision detector, thereby controlling the lifting hydraulic component to raise the front atomizing roller or lower the rear atomizing roller. In this way, when there are many or large hard objects causing intense collisions, if the collision detector detects that the collision intensity is greater than a predetermined threshold, the controller automatically controls the lifting hydraulic component to raise the front atomizing roller or lower the rear atomizing roller, thereby increasing or decreasing the inclination of the rolling surface. This balances atomization efficiency, the impact of soil particles on the atomization chamber, and the collision with hard objects.

[0014] In a further 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 means of springs; the collision detector is a vibration detector for detecting the vibration of the inner vibrating plate.

[0015] In an optional technical solution, multiple inner vibrating plates are included; the position difference adjustment system includes multiple collision detectors; each inner vibrating plate corresponds to at least one collision detector. This allows the lifting support to be controlled according to a predetermined strategy, such as based on the average vibration of multiple inner vibrating plates or based on the maximum vibration frequency or intensity of the inner vibrating plates.

[0021] 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.

[0022] 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.

[0023] 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. In this embodiment, the walking system is a tracked walking system. To adapt to the desert environment, in this embodiment, the walking system includes tracks located on both sides. The walking system can be self-powered and move on its own; 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 on its own.

[0024] 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.

[0025] 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 and ensure the power supply to the atomizing roller.

[0026] In this way, during the movement of the desert soil treatment machine, 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 rotate at an appropriate speed. The atomizing blades of the rollers carry the soil into the atomization chamber. The rotation at the appropriate speed causes 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 and 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 surface layer.

[0027] Figure 4 for Figure 1 The diagram shows the working principle of the desert soil atomization system in a mobile desert soil treatment machine. In one embodiment of the invention, in this mobile desert soil treatment machine, the top of the rear atomizing roller 320b is lower than the top of the front atomizing roller 320a, that is, the height difference between the top of the rear atomizing roller 320b and the top of the front atomizing roller 320a is H1. Thus, during the atomization process, the relatively rotating front atomizing roller 320a and rear atomizing roller 320b carry stones or other hard objects to the atomization mixing space between the inner wall of the atomization chamber 310 and the upper part of the atomizing rollers, where they remain. Because the top of the rear atomizing roller 320b is lower than the top of the front atomizing roller 320a, a generally backward-sloping "rolling surface" is formed on the upper part of the atomizing roller; the inclined rolling surface can guide the remaining hard objects S backward and cause them to fall back from behind the rear atomizing roller 320b (e.g., Figure 4(As shown by the dashed arc arrow), this can reduce the retention of hard objects in the atomization mixing space, improve the atomization mixing effect of the atomization mixing space, and at the same time reduce the collision of hard objects with the atomization chamber plate and atomization roller, reduce component damage, and reduce safety hazards.

[0028] In the preferred embodiment, the front atomizing roller 320a and the rear atomizing roller 320b are identical. This allows for the interchangeability of the front and rear atomizing rollers, and through periodic interchange, balanced wear of the front and rear atomizing rollers is achieved, improving the maintainability of the mobile desert soil treatment machine. When the front atomizing roller 320a and the rear atomizing roller 320b have the same outline dimensions, the rotation axis of the rear atomizing roller 320b can be lower than the rotation axis of the front atomizing roller 320a. For example, the height difference between the rotation axes of the rear atomizing roller 320b and the front atomizing roller 320a can be H2, resulting in the top of the rear atomizing roller 320b being lower than the top of the front atomizing roller 320a, forming a roughly rearward-sloping "rolling surface." During the operation of the embodiment, the inventors found that if the tilt of the "rolling surface" is too large, although it can guide the hard object to move backward and fall back into the soil layer (the soil after preliminary treatment) more smoothly, it will increase the impact of soil particles on the atomization chamber, which is not conducive to mixing and stability in the atomization chamber. Therefore, the "rolling surface" can be made to have a suitable tilt. Thus, the height difference H1 between the top of the rear atomizing roller 320b and the top of the front atomizing roller 320a should also be kept within a suitable range. For example, the height difference H1 can be greater than one-tenth of the diameter of the rear atomizing roller 320b and less than two-tenths of the diameter of the rear atomizing roller 320b, so as to achieve a balance between atomization efficiency, the impact of soil particles on the atomization chamber and the collision of hard objects S.

[0029] A mobile desert soil treatment machine, wherein 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 front atomizing roller 320a... The projections of the atomizing fins 322 of the front atomizing roller 320a and the rear atomizing roller 320b onto the plane perpendicular to the axis of rotation overlap, ensuring that the front atomizing roller 320a and the rear atomizing roller 320b maintain an appropriate overlap, i.e., 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 rotation sections of the front atomizing roller 320a and the rear atomizing roller 320b maintain an appropriate overlap.

[0030] In the preferred technical solution, the mobile desert soil treatment machine also includes a lifting support 410 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 410, that is, one of the front atomizing roller 320a or the rear atomizing roller 320b is rotatably mounted on the lifting support 410, while the other can remain 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 according to the actual soil layer being treated, the height difference between the front atomizing roller 320a or the rear atomizing roller 320b can be increased or decreased to form rolling surfaces with different inclinations, so that the hard, lumpy objects S entrained in the atomization mixing space by the front atomizing roller 320a and the rear atomizing roller 320b can be guided back as quickly and smoothly as possible.

[0031] Please combine Figure 3 ,refer to Figure 5 , Figure 5 for Figure 4 A block diagram of the position difference adjustment system of the mobile desert soil treatment machine. The mobile desert soil treatment machine also includes a position difference adjustment system, which includes a lifting hydraulic component 510, a collision detector 520, a lifting solenoid valve 530, and a controller 450; the lifting hydraulic component 510 drives the lifting support 410 to rise and fall relative to the frame 100; the lifting solenoid valve 530 is connected between the lifting hydraulic component 510 and the hydraulic oil source; the collision detector 520 is used to detect the collision state experienced by the inner wall of the atomizing chamber plate 310 and generate a collision intensity signal.

[0032] The output terminal of the collision detector is connected to the signal terminal of the controller 450 to output a collision intensity signal to the controller 450. The control terminal of the controller 450 is connected to the lifting solenoid valve 530 to control the lifting solenoid valve 530 according to the collision intensity signal generated by the collision detector, thereby controlling the lifting hydraulic component 510, which in turn raises the front atomizing roller 320a or lowers the rear atomizing roller 320b. 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 automatically controls the lifting hydraulic component 510 to raise the front atomizing roller 320a or lower the rear atomizing roller 320b, increasing or decreasing the inclination of the rolling surface. This balances atomization efficiency, the impact of soil particles on the atomization chamber, and the collision with hard objects.

[0033] 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.

[0034] See again Figure 4 To facilitate vibration intensity detection, the mobile desert soil treatment machine may further include an inner vibrating plate 540, which is mounted on the inner wall of the atomizing chamber plate 310 via springs. The collision detector 520 is a vibration detector for detecting the vibration of the inner vibrating plate 540. Multiple inner vibrating plates 540 may also be included; the position difference adjustment system includes multiple collision detectors 520; each inner vibrating plate 540 corresponds to at least one collision detector 520. This allows the lifting support 410 to be raised and lowered according to a predetermined strategy, such as based on the average vibration of multiple inner vibrating plates 540 or based on the maximum vibration frequency or intensity of the inner vibrating plates 540.

[0035] The specific embodiments provided by the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention, and the descriptions of the embodiments above are only for the purpose of helping to understand the core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
