Description

Technical Field

[0001] The invention relates to the technical field of imported soil spraying machinery, in particular to a imported soil spraying and stirring device. Background Art

[0002] Soil spraying is a process of spraying soil mixed with plant seeds, fertilizers and other additives onto the excavated slope surface for protection and greening. The main process of the spraying part of this process is divided into: first, select suitable planting soil and screen out fine particles for standby; second, mix the screened planting soil with fertilizers and other ingredients; third, spray the mixed soil onto the slope surface through a pressure device such as an air compressor.

[0003] Currently, a soil sprayer is often used as the primary spraying equipment for soil spraying. A search revealed a soil sprayer disclosed in patent application number CN201820114630.5 and IPC classification number A01C7 / 00 (20060101). Its main structure includes a frame, a stirring mechanism, and a spraying mechanism. The stirring mechanism includes a stirring barrel with a feed inlet and a discharge outlet, which is mounted on the frame via a support shaft, and a plurality of stirring shafts disposed within the stirring barrel. The stirring shafts are evenly distributed with a plurality of first stirring blades, and the stirring barrel is provided with a drive assembly for driving the stirring shafts to rotate along the circumference of the stirring barrel.

[0004] When the above-mentioned soil sprayer is working, the raw materials are put into the mixing barrel from the feed port, and then the driving assembly drives several stirring shafts to rotate synchronously along the circumference of the mixing barrel to stir the materials in the mixing barrel. The stirring effect is enhanced by the synchronous rotation of multiple stirring shafts, making the material mixing more uniform.

[0005] However, when using the above-mentioned spraying equipment to complete the spraying process, dry soil is screened in the fine soil screening stage, and then sent into the mixer for mixing and then sprayed, that is, it is mainly used for dry soil spraying, but this spraying method has the following problems: First, the use scenario is limited: due to the influence of on-site soil sources and seasonal construction in the rainy season, it is not easy to organize dry soil spraying construction during the rainy season, which makes this equipment easy to affect the project schedule when used in the rainy season; second, the use of dry soil requires soil preparation in advance.

[0028] Example 1: A foreign soil spraying and mixing device comprises a mounting base 1, the mounting base 1 is used to be mounted on an external construction vehicle and move with the construction vehicle, two oppositely arranged left bearing seats 2 and right bearing seats 3 are fixedly mounted on both sides of the top of the mounting base 1, a foreign soil storage and processing unit 4 is arranged between the left bearing seat 2 and the right bearing seat 3, the right end of the foreign soil storage and processing unit 4 is movable through to the outside of the right bearing seat 3 and is connected to a grading power unit 5, the bottom of the grading power unit 5 is fixedly mounted on the top of the mounting base 1, and the grading power unit 5 is fixedly mounted on the top of the mounting base 1. A foreign soil slurry feeding unit 6 is installed on the upper part of the stage power unit 5. The feeding end of the foreign soil slurry feeding unit 6 is used to receive the foreign soil slurry material transported from the outside.

The two ends of the external drive mixing unit are respectively movable through the left bearing seat 2 and the right bearing seat 3. The outer end of the external drive mixing unit is connected to the grading power unit 5 and is driven by it.

[0029] It should be noted that the foreign soil spraying and stirring device in the present invention is directly installed on the construction vehicle when in use. The device is started by turning on the power supply, and the feed end of the foreign soil slurry feeding unit 6 is used to receive the external foreign soil slurry material. When the foreign soil slurry material enters the foreign soil storage processing unit 4, the foreign soil storage processing unit 4 relies on the mixing and stirring of the incoming material and the refinement of the particle size to achieve uniform and refined mud material, waiting for spraying; when spraying is required, the mud pump 19 of the foreign soil mud spraying unit 7 is started to spray the stirred mud directly outward to achieve rapid spraying operation.

[0030] Before spraying, the grading power unit 5 provides power to drive the current imported soil storage processing unit 4 and the external driving mixing unit to improve the processing effect of the current internal mud.

[0031] In any of the above schemes, it is preferred that the foreign soil storage processing unit 4 includes a horizontally arranged hollow mud steel pipe 8, and the hollow mud steel pipe 8 separates the cavities at both ends of the hollow mud steel pipe 8 into a feeding chamber 10 and a discharging chamber 11 through a blocking portion 9 in the middle thereof. The right end of the feeding chamber 10 is communicated and coordinated with the foreign soil mud feeding unit 6, and the left end of the discharging chamber 11 is communicated and coordinated with the foreign soil mud spraying unit 7.

Large gears 15 are fixedly installed on the outer walls of both ends of the horizontal storage barrel 12, and the bottom of each large gear 15 is meshed with the small gear 16 on the external drive mixing unit.

[0032] It should be noted that the imported soil storage processing unit 4 designed in the present invention mainly relies on the hollow mud steel pipe 8 as the main support member. The two ends of the hollow mud steel pipe 8 are movably supported and can complete fixed-axis rotation under the action of external power. During the fixed-axis rotation, the internal mud material is mixed and stirred, effectively improving the processing effect of the internal imported soil slurry.

[0033] In addition, since the engagement of the large gear 15 on the outer wall of the horizontal storage barrel 12 and the small gear 16 on the external drive mixing unit can effectively ensure the mutual linkage of the entire structure, and at the same time, the hollow mud rigid pipe 8 and the horizontal storage barrel 12 can be rotated asynchronously, effectively improving the stirring treatment effect of the internal mud material.

[0034] In any of the above schemes, it is preferred that the external drive mixing unit includes a horizontally arranged slow stirring rigid shaft 17, and the two ends of the slow stirring rigid shaft 17 are respectively movable through the left bearing seat 2 and the right bearing seat 3 and extend to their respective outsides, and the right end of the slow stirring rigid shaft 17 is connected to the output end of the grading power unit 5, and the grading power unit 5 drives the slow stirring rigid shaft 17 to rotate when it is in operation.

When the first center bevel gear 30 is working, it can drive the slow stirring rigid shaft 17 to operate, and finally achieve the purpose of driving the two small gears 16 thereon to rotate. When the small gear 16 rotates, it can drive the large gear 15 meshing with it and the hollow mud rigid pipe 8 fixed to the large gear 15 to realize rotational motion, thereby achieving effective slow mixing of the mud material in the annular storage stirring chamber 14 by rotating from the outside.

[0037] When the mud material inside the annular storage stirring chamber 14 is processed, it can enter the spraying suction pipe 18 through the negative pressure suction of the mud pump 19, and then enter the mud pump 19 through the spraying suction pipe 18, and finally be quickly sent to the imported soil mud spraying unit 7 through the mud pump 19 and complete the spraying operation outward.

[0038] In any of the above schemes, preferably, a telescopic blocking displacement member is installed in the cavity between the right end of the three-way suction pipe 20 and the blocking portion 9, and the telescopic blocking displacement member is used to realize the opening and closing control of the two spraying suction pipes 18.

[0039] The telescopic blocking displacement member includes a telescopic cylinder 21 fixedly installed in the cavity between the right end of the three-way suction pipe 20 and the blocking part 9, and a blocking piston 22 is fixedly installed at the left end of the piston rod of the telescopic cylinder 21. The outer wall of the blocking piston 22 is sealed with the inner wall of the discharge cavity 11. The length of the blocking piston 22 is greater than the inner diameter of the pipe mouth of the spraying suction pipe 18. When the blocking piston 22 is working, it is used to block the pipe mouths of the two spraying suction pipes 18 and prevent the mud material from entering the discharge cavity 11.

[0040] In any of the above schemes, it is preferred that mud internal nozzles 23 connected to the interior of the feed chamber 10 are respectively provided at the upper and lower parts of the right end on the right side of the blocking portion 9, and the outlet ends of each mud internal nozzle 23 are respectively connected to the interior of the annular storage stirring chamber 14 and are used to transport the imported soil slurry into the interior.

[0041] The slurry material transported into the feed chamber 10 of the device under the action of external transport power can be transported into the annular storage and stirring chamber 14 through the corresponding slurry inner nozzle 23 to continue subsequent mixing and stirring.

[0042] In any of the above schemes, it is preferred that the graded power unit 5 includes a mounting chamber 24 fixedly mounted on the top right end of the mounting seat 1, and an upper chamber 25, a middle chamber 26, and a lower chamber 27 are sequentially arranged from top to bottom inside the mounting chamber 24. A reducer 28 is installed in the lower chamber 27, and the right end of the reducer 28 extends to the outside of the mounting chamber 24 and is connected to the main drive motor 29 fixed on the top of the mounting seat 1. A first central bevel gear 30 is installed inside the middle chamber 26, and the left end of the first central bevel gear 30 is fixedly connected to the first central bevel gear 30. A drive input gear 31 is engaged below the first central bevel gear 30. It is fixedly connected to the output shaft of the reducer 28, and a clutch component is engaged above the first center bevel gear 30. The clutch component is installed at the partition between the upper cavity 25 and the middle cavity 26. The lower end of the clutch component extends into the middle cavity 26, and the upper end of the clutch component extends into the upper cavity 25. A second center bevel gear 32 is installed in the upper cavity 25. The second center bevel gear 32 and the right end of the slow-stirring rigid shaft 17, the left end of the second center bevel gear 32 are fixedly installed on the outer side wall of the end flange tube 33 at its corresponding position, and the left end of the end flange tube 33 is fixed to the right end of the hollow mud rigid pipe 8 and the two are internally connected.

[0043] When the grading power unit 5 is working, it relies on the main drive motor 29 as the single power. The main drive motor 29 drives the reducer 28 to operate. The reducer 28 outputs power to the external drive mixing unit or synchronously outputs power to the external drive mixing unit and the hollow mud steel pipe 8 of the imported soil storage processing unit 4; thereby achieving the purpose of output on demand.

[0044] When the external drive mixing unit receives power, it will drive the entire horizontal storage barrel 12 to rotate; when the hollow mud steel pipe 8 of the imported soil storage processing unit 4 rotates, it can drive the spraying suction pipe 18 and the mud internal nozzle 23 in the annular storage mixing chamber 14 to rotate and serve as a primary stirring component.

[0045] In any of the above schemes, it is preferred that a left-side multidirectional agitator is installed on one side of the pipe mouth of each of the spraying suction pipes 18; a right-side multidirectional agitator is installed on one side of the pipe mouth of each of the mud nozzles 23, and each of the left-side multidirectional agitators and each of the right-side multidirectional agitators can rotate along with the hollow mud steel pipe 8 and can each rotate under the flow of the imported soil slurry.

[0046] In any of the above schemes, it is preferred that the clutch component includes a clutch 34 installed at the partition between the upper cavity 25 and the middle cavity 26, the output shaft of the clutch 34 extends into the interior of the upper cavity 25 and is connected to the upper bevel gear 35, the lower end of the input shaft of the clutch 34 extends into the interior of the middle cavity 26 and is connected to the lower bevel gear 36, the upper bevel gear 35 is meshed with the second center bevel gear 32, the lower bevel gear 36 is meshed with the first center bevel gear 30, and an auxiliary bevel gear 37 is meshed above the second center bevel gear 32, and the upper end of the gear shaft of the auxiliary bevel gear 37 is movably inserted into the mounting hole at the top of the upper cavity 25.

[0047] The main function of the clutch component is to control the connection or cutoff of power to the hollow mud steel pipe 8, thereby controlling the stirring effect in the annular material storage stirring chamber 14.

[0048] Example 2: Compared with Example 1, this example is different in that it also includes the following technical features:

[0049] In any of the above schemes, it is preferred that each of the left-side multidirectional agitators and each of the right-side multidirectional agitators adopts a multidirectional stirring structure with the same structure, and the multidirectional stirring structure includes an open shell 38 fixedly mounted on the outer wall of the hollow mud steel pipe 8, and an eccentric gear 39 is installed in the shell cavity 40 of the open shell 38. The eccentric gear 39 and the pipe mouth of the spraying suction pipe 18 or the pipe mouth of the mud nozzle 23 at its corresponding position are eccentrically set, and both ends of the central axis 41 of each of the eccentric gears 39 are movably inserted into the corresponding mounting holes on the inner wall of the shell cavity 40. When each of the eccentric gears 39 is impacted by the imported soil slurry, it can realize fixed-axis rotation and stirring.

[0050] The left-side multi-directional agitator and the right-side multi-directional agitator designed here can cooperate with the rotation of the existing spray suction pipe 18 and the mud nozzle 23 in the annular storage stirring chamber 14 as the first-level stirring component to complete further internal rotation stirring; at the same time, cooperate with the rotation of the external horizontal storage barrel 12 to achieve three-stage mixing and stirring, thereby accelerating the processing effect and efficiency of the mud material.

[0051] The multi-directional agitator on the left and the multi-directional agitator on the right both adopt an eccentric design structure that keeps the impact force of the mud material, so that the impact force of the mud can effectively ensure the driving rotation of the current eccentric gear 39, ensuring the initial spreading of the incoming mud material at the initial stage of feeding or further completing the terminal mixing of the mud material before spraying, thereby improving the spraying effect.

[0052] Specific working principle: This foreign soil spraying and stirring device is directly installed on the construction vehicle when in use. The device is started by turning on the power supply, and the feed end of the foreign soil slurry feeding unit 6 is used to receive the external foreign soil slurry. When the foreign soil slurry enters the foreign soil storage processing unit 4, the foreign soil storage processing unit 4 relies on the mixing and stirring of the incoming material and the refinement of the particle size to achieve uniform and refined slurry material, waiting for spraying; when spraying is required, the mud pump 19 of the foreign soil mud spraying unit 7 is started to spray the stirred mud directly outward to achieve rapid spraying operation; before spraying, the grading power unit 5 provides power to complete the driving of the current foreign soil storage processing unit 4 and the external drive mixing unit to achieve the improvement of the current internal mud processing effect.

[0053] Specifically, the imported soil storage material processing unit 4 mainly relies on the hollow mud steel pipe 8 as the main support. The two ends of the hollow mud steel pipe 8 are movably supported and can complete fixed-axis rotation under the action of external power. During the fixed-axis rotation, the internal mud material is mixed and stirred, effectively improving the processing effect of the internal imported soil slurry material.

[0054] Because the meshing of the large gear 15 on the outer wall of the horizontal storage barrel 12 and the small gear 16 on the external drive mixing unit can effectively ensure the mutual linkage of the entire structure, and at the same time can achieve the purpose of asynchronous rotation of the hollow mud steel pipe 8 and the horizontal storage barrel 12, effectively improving the stirring and processing effect of the internal mud material. In addition, the left multi-directional agitator and the right multi-directional agitator can cooperate with the existing primary stirring component, the spraying suction pipe 18 and the mud nozzle 23 in the annular storage stirring chamber 14 to complete further internal rotation stirring; at the same time, cooperate with the rotation of the external horizontal storage barrel 12 to achieve three-level mixing and stirring, accelerating the processing effect and efficiency of the mud material.

[0055] In summary, the foreign soil spraying and stirring device can collect and store the foreign soil slurry that has not been stirred and mixed through a single power component, and complete slow stirring or fast double-effect mixing inside the foreign soil storage processing unit 4, effectively improving the processing effect of the internal foreign soil material, effectively ensuring that the foreign soil slurry is fully stirred and mixed, and ensuring the subsequent spraying effect during outward spraying and the homogeneity of the sprayed mud material; wherein, the foreign soil storage processing unit 4 and the external drive mixing unit both realize the input and transmission of power through the graded power unit 5, effectively ensuring the diversity of modes when the foreign soil slurry is mixed and processed, providing a strong mode of external slow rotation mixing and internal and external rotation mixing and stirring, and better completing multi-effect material processing according to the needs of spraying. The present invention can be installed on a construction vehicle for use, better realizing efficient and fast mixing of the sprayed soil slurry, effectively improving the uniformity of the foreign soil slurry, better meeting the needs of spraying, and improving the quality of spraying.
