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

[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 bin plate, two atomization rollers and a roller drive device; the atomization bin plate forms an atomization bin with an opening below; the atomization roller is rotatably mounted on the frame; the atomization roller includes an atomization wing head extending radially outward; in the extension direction of the rotation axis, the atomization wing head of the front atomization roller and the atomization wing head of the rear atomization roller are arranged alternately. In this way, during the movement of the desert soil treatment machine, the atomization roller can be located below the surface of the desert soil to be treated and rotated, so that the atomization wing head can be used to bring the soil to be treated into the atomization bin, so that the surface soil is atomized, thereby providing a prerequisite for the atomization of the modifier and the surface soil, and then providing a prerequisite for the combination of the modifier and the desert soil, so as to achieve the treatment of the surface layer of the desert soil, form a protective layer of the desert surface, and even passivate the desert surface.

[0004] How to avoid or reduce the above problems and improve the processing efficiency and safety of the mobile desert soil processor is an issue that needs to be further improved or resolved. Summary of the invention

[0005] The object of the present invention is to provide a mobile desert soil processing machine with an atomizing roller that is high at the front and low at the back, and the mobile desert soil processing machine has higher processing efficiency and safety.

[0006] To this end, the present invention provides a mobile desert soil treatment machine, including a frame, a walking system and a desert soil atomization system; the walking system is installed on the frame; the desert soil atomization system includes an atomization bin plate, a front atomization roller and a rear atomization roller; the front atomization roller and the rear atomization roller are rotatably installed on the frame in the front and rear directions, and are arranged in pairs in the atomization bin, and the top of the rear atomization roller is lower than the top of the front atomization roller. During the atomization process, the relatively rotating front atomization roller and the rear atomization roller bring the atomization bin to bring stones or other hard objects to the atomization mixing space between the inner wall of the atomization bin and the upper part of the atomization roller, and retain them in the atomization mixing space. Since the top of the rear atomizing roller is lower than the top of the front atomizing roller, a "rolling surface" that is roughly inclined backward is formed on the upper part of the atomizing roller; the inclined rolling surface can guide the retained hard and fast objects backward and fall back from the rear of the rear atomizing roller, thereby reducing the retention of hard and fast objects in the atomizing mixing space, improving the atomizing mixing effect of the atomizing mixing space, and at the same time reducing the collision of hard and fast objects on the atomizing bin plate wall and the atomizing roller, reducing component damage and reducing safety hazards.

[0007] In the preferred technical solution, the front atomizing roller and the rear atomizing roller are identical, so that the front and rear atomizing rollers can be interchanged, and the wear of the front and rear atomizing rollers can be balanced by regular interchange, thereby improving the maintenance performance of the mobile desert soil treatment machine.

[0008] In a preferred technical solution, the rotation axis of the rear atomizing roller is lower than the rotation axis of the front atomizing roller, so that the top of the rear atomizing roller is 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. At the same time, 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 the preferred technical solution, the front atomizing roller and the rear atomizing roller both include a central axis body and atomizing wings installed on the surface of the central axis body and extending radially outward; the rotation axes of the front atomizing roller and the rear atomizing roller are transversely parallel; in the extension direction of the rotation axis, the atomizing wings of the front atomizing roller and the atomizing wings of the rear atomizing roller are staggered, and the projections of the atomizing wings of the front atomizing roller and the atomizing wings of the rear atomizing roller in a plane perpendicular to the rotation axis form an overlap, even if the front atomizing roller and the rear atomizing roller maintain an appropriate partial overlap.

[0011] In a preferred embodiment of the present invention, the mobile desert soil treatment machine may further include a lifting bracket that is liftably mounted on the frame; the front atomizing roller or the rear atomizing roller is rotatably mounted on the lifting bracket, that is, one of the front atomizing roller or the rear atomizing roller is rotatably mounted on the lifting bracket, and the other may 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 the height difference of the front atomizing roller or the rear atomizing roller can be increased or decreased according to the actual situation of the soil layer being treated, so as to form rolling surfaces with different inclinations, so that the hard and fast objects that are entrained into the atomizing mixing space by the front atomizing roller and the rear atomizing roller can be guided back as quickly and smoothly as possible.

[0012] In a further technical solution, the mobile desert soil treatment machine also includes a position difference adjustment system, which includes a lifting hydraulic element, a collision detector, a lifting electric control valve and a controller; the lifting hydraulic element drives the lifting bracket to lift relative to the frame; the lifting electric control valve is connected between the lifting hydraulic element and the hydraulic oil source; the collision detector is used to detect the collision state of the inner wall of the atomizing bin plate and generate a collision intensity signal; The output end of the collision detector is connected to the signal end of the controller to output a collision intensity signal to the controller; the control end of the controller is connected to the lifting electric control valve signal to control the lifting electric control valve according to the collision intensity signal generated by the collision detector, and then control the lifting hydraulic element, so as to raise the front atomizing roller or lower the rear atomizing roller. In this way, when there are many or large hard objects and the collision is more intense, when the collision detector detects that the collision intensity is greater than a predetermined threshold, the controller automatically controls the lifting hydraulic element, so as to raise the front atomizing roller or lower the rear atomizing roller, and increase or decrease the inclination of the rolling surface, so as to achieve a balance between atomization efficiency, the impact of soil particles on the atomizing bin, and the collision of hard objects.

[0020] The following is a detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings. It should be noted that in this document, the directional words are determined with reference to the use status of the mobile desert soil treatment machine.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 An external stereoscopic diagram of a mobile desert soil treatment machine provided by an embodiment of the present invention; Figure 2 for Figure 1 A longitudinal sectional view of a mobile desert soil treatment machine is shown in FIG. Figure 3 for Figure 1 The present invention provides a mobile desert soil processing machine including a frame 100, a walking system 200 and at least one desert soil atomization system 300.

[0022] The walking system 200 is installed on the frame 100, which can facilitate the movement of the desert soil treatment machine and improve the treatment efficiency. The walking system 200 can be a vehicle or mechanical mobile system, which can be a wheeled walking system or a walking system of other structures. In this embodiment, the walking system is a crawler walking system. In order to adapt to the desert environment, in this embodiment, the walking system includes walking crawlers located on both sides. The walking system can be self-powered and can move by itself; it can also be unpowered and can be dragged by other equipment. In this embodiment, the walking system of the mobile desert soil treatment machine is self-powered and can move by itself.

[0023] like Figure 2 and Figure 3As shown, in this embodiment, the mobile desert soil treatment machine includes three desert soil atomization systems 300 arranged in sequence from front to back. The desert soil atomization system 300 includes an atomization bin plate, two atomization rollers 320 and a roller drive device; the atomization bin plate forms an atomization bin with an opening at the bottom. In each atomization bin, the front and rear atomization rollers are arranged in pairs, and the reference numerals are 320a and 320b respectively; in special circumstances, more atomization rollers can also be arranged.

[0024] The desert soil atomization system 300 is also provided with a roller drive device, which can be installed on the frame 100 to drive the front atomization roller 320a and the rear atomization roller 320b to rotate. In this embodiment, each atomization roller is provided with a separate roller drive device to control the rotation speed of the atomization roller respectively and ensure the power supply of the atomization roller.

[0025] 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 located at an appropriate position below the surface of the desert soil to be treated, and rotated at an appropriate speed, so as to use the atomizing wing head of the atomizing roller to bring the soil to be treated into the atomizing bin. The rotation at an appropriate speed can make the surface soil fly, realize soil atomization, and then provide a prerequisite for the atomization and mixing of the modifier and the surface soil, realize the surface treatment of the desert soil, form a desert surface protective layer, and even passivate the desert surface. In one embodiment, the front atomizing roller 320a and the rear atomizing roller 320b can be located about 200mm below the surface of the desert soil to be treated, that is, the soil within 200mm of the desert surface can be passivated.

[0026] Figure 4 for Figure 1 The working principle diagram of the desert soil atomization system of the mobile desert soil treatment machine is shown. In one embodiment of the present invention, in the 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 H2. In this way, during the atomization process, the relatively rotating front atomizing roller 320a and the rear atomizing roller 320b bring stones or other hard objects to the atomization mixing space between the inner wall of the atomization bin 310 and the upper part of the atomizing roller, and retain them in the atomization mixing space. Since the top of the rear atomizing roller 320b is lower than the top of the front atomizing roller 320a, a "rolling surface" that is roughly tilted backwards is formed on the upper part of the atomizing roller; the tilted rolling surface can guide the retained hard objects S backwards and fall back from the rear of the rear atomizing roller 320b (such as Figure 4The invention also can reduce the hard and fast objects from being retained in the atomizing and mixing space, improve the atomizing and mixing effect of the atomizing and mixing space, and reduce the collision of the hard and fast objects with the atomizing bin plate, the atomizing roller, the damage of the components, and the potential safety hazards.

[0027] In the preferred technical solution, the front atomizing roller 320a and the rear atomizing roller 320b are the same. In this way, the front and rear atomizing rollers can be interchanged. By regularly exchanging, the wear of the front and rear atomizing rollers can be balanced, and the maintenance performance of the mobile desert soil treatment machine can be improved. 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 made lower than the rotation axis of the front atomizing roller 320a, such as making the height difference between the rotation axis of the rear atomizing roller 320b and the rotation axis of the front atomizing roller 320a be H2, thereby making the top of the rear atomizing roller 320b lower than the top of the front atomizing roller 320a, forming a "rolling surface" that is roughly tilted backwards. During the operation of the embodiment, the inventor found that if the inclination of the "rolling surface" is too large, although it can more smoothly guide the hard fast objects to move backward and fall back into the soil layer (soil after preliminary treatment), it will increase the impact of soil particles on the atomization bin, which is not conducive to mixing and stability in the atomization bin. Therefore, the "rolling surface" can have a suitable inclination. Therefore, the height difference H1 between the top of the rear atomization roller 320b and the top of the front atomization roller 320a should also be kept within an appropriate range. For example, the height difference H1 can be greater than one tenth of the diameter of the rear atomization roller 320b and less than two tenths of the diameter of the rear atomization roller 320b, so as to achieve a balance among the atomization efficiency, the impact of soil particles on the atomization bin and the collision of the hard fast objects S.

[0028] A mobile desert soil treatment machine, wherein the front atomizing roller 320a and the rear atomizing roller 320b each include a central axis 321 and an atomizing wing head 322 mounted on the surface of the central axis 321 and extending radially outward; the rotation axes of the front atomizing roller 320a and the rear atomizing roller 320b are transversely parallel; in the extension direction of the rotation axis, the atomizing wing head 322 of the front atomizing roller 320a and the atomizing wing head 322 of the rear atomizing roller 320b are staggered, and the front atomizing roller 320a and the rear atomizing roller 320b are staggered. The projections of the atomizing wing head 322 of the atomizing roller 320a and the atomizing wing head 322 of the rear atomizing roller 320b in a plane perpendicular to the rotation axis form an overlap, so that the front atomizing roller 320a and the rear atomizing roller 320b maintain an appropriate partial overlap, that is, 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 rotating cross-sections of the front atomizing roller 320a and the rear atomizing roller 320b maintain an appropriate overlap.

[0029] In the preferred technical solution, the mobile desert soil treatment machine also includes a lifting bracket 410 that can be lifted and lowered on the frame 100; the front atomizing roller 320a or the rear atomizing roller 320b is rotatably mounted on the lifting bracket 410, that is, one of the front atomizing roller 320a or the rear atomizing roller 320b is rotatably mounted on the lifting bracket 410, and the other can remain fixed. Through the height adjustment 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 in an appropriate range; and according to the actual situation of the soil layer being processed, the height difference of 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 and fast objects S that are entrained into the atomizing mixing space by the front atomizing roller 320a and the rear atomizing roller 320b can be guided back as quickly and smoothly as possible.

[0030] Please combine Figure 3 ,refer to Figure 5 , Figure 5 for Figure 4 Block diagram of the position difference adjustment system of the mobile desert soil processing machine. The mobile desert soil processing machine also includes a position difference adjustment system, which includes a lifting hydraulic element 510, a collision detector 520, a lifting electric control valve 530 and a controller 450; the lifting hydraulic element 510 drives the lifting bracket 410 to rise and fall relative to the frame 100; the lifting electric control valve 530 is connected between the lifting hydraulic element 510 and the hydraulic oil source; the collision detector 520 is used to detect the collision state of the inner wall of the atomizing bin plate 310 and generate a collision strength signal.

[0031] The output end of the collision detector is connected to the signal end of the controller 450 to output a collision intensity signal to the controller 450; the control end of the controller 450 is connected to the lifting electric control valve 530 to control the lifting electric control valve 530 according to the collision intensity signal generated by the collision detector, and then control the lifting hydraulic element 510, so as to make the front atomizing roller 320a rise, or make the rear atomizing roller 320b fall. In this way, when there are many or large hard objects and the collision is more intense (vibration frequency value, sound intensity value or collision force value), when the collision detector detects that the collision intensity is greater than a predetermined threshold, the controller automatically controls the lifting hydraulic element 510, so as to make the front atomizing roller 320a rise, or make the rear atomizing roller 320b fall, so as to increase or decrease the rolling surface inclination, so as to achieve a balance between atomization efficiency, the impact of soil particles on the atomizing bin and the collision of hard objects.

[0032] The collision detector may be a vibration detection device, a sound detection device, or a force detection device, etc., so as to determine the collision intensity through vibration, sound or collision force.

[0033] Refer to Figure 4 In order to facilitate the detection of vibration intensity, the mobile desert soil treatment machine may further include an inner layer vibration plate 540, which is installed on the inner wall surface of the atomizing bin plate 310 through a spring member; the collision detector 520 is a vibration detector for detecting the vibration of the inner layer vibration plate 540. It may also include multiple inner layer vibration plates 540; the position difference adjustment system includes multiple collision detectors 520; any inner layer vibration plate 540 corresponds to at least one collision detector 520.
