Description

Technical Field

[0001] The utility model relates to the field of building engineering construction, in particular to a closed material feeding and mixing integrated vehicle. Background Art

[0002] The moisture content of mud dried soil and other urban waste soil belongs to the high-humidity category. When entering the crushing and mixing device, it is easy to have bonding equipment and unsatisfactory crushing particle size, resulting in a decrease in the yield of the final qualified finished product. In the current treatment, quicklime needs to be added to the mud cake and the abandoned soil from the foundation pit excavation. After a certain period of static reaction, the moisture content in the high-humidity abandoned soil will gradually decrease and become sandy. The abandoned soil after sandification has the characteristics of looseness and low viscosity, which is convenient for the crushing and mixing device to handle. However, this method has the following defects: 1. The amount of dust is extremely large during the process of ash turning and mixing, which endangers the health of the operating workers; 2. The amount of quicklime input is huge, resulting in a high cost of regeneration treatment; the static reaction time is long (generally seven days), and the lime attenuation can reach 30-43%; 3. It is not conducive to improving production efficiency, and requires sufficient product and semi-finished product stacking space.

[0003] To solve the above defects, Figure 1 As shown, the applicant's prior application proposed a feeding and mixing integrated vehicle (see CN202320669580.8 for details), which improves the treatment efficiency of waste mud and reduces the treatment cost. The integrated vehicle adopts a mechanical arm with a soil scraping mechanism, which is dedicated to crushing and feeding waste soil, and transports the waste soil to the feeding and mixing part at the rear end through a conveyor belt for crushing and mixing, thereby achieving efficient regeneration of waste soil.

[0004] However, the above-mentioned feeding and mixing vehicle still has the following defects in actual application: the operation of the soil digging mechanism and the soil feeding mechanism is an open operation, which is easy to generate dust, making the working environment dusty, affecting the health of workers and the image of the factory.

[0005] Based on this, this case is brought forward. Utility Model Content

[0039] The present invention is further described in detail below in conjunction with the embodiments. It should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" herein are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0040] This embodiment provides a closed type material feeding and mixing vehicle. Fig. 9As shown, it includes a crawler-type mobile base 1, on which a turntable 18 is installed, and a connecting seat 19 and a hydraulic cylinder 20 are provided on the turntable 18. The bottom of the connecting seat 19 is welded and fixed on the turntable 18, and the cylinder end of the hydraulic cylinder 20 is rotatably connected to the turntable 18. The integrated vehicle also includes a conveyor belt device 22, the bottom of which is rotatably connected to the connecting seat 19, and the piston end of the hydraulic cylinder 20 is rotatably connected to the bottom of the conveyor belt device 22. By lifting the hydraulic cylinder 20, the conveyor belt device 22 can be adjusted up and down like a seesaw (i.e., vertical rotation). The crawler-type mobile base 1 is used to drive the conveyor belt device 22 to move, and the turntable 18 realizes the horizontal rotation of the conveyor belt device 22.

[0041] like Figures 1 to 8 As shown, a bucket 2, a soil scraping mechanism 3 and a soil delivery mechanism 4 are provided at the front feed port of the conveyor belt device 22. The rear side of the bucket 2 is connected and fixed to the feed port side of the conveyor belt device 22, and the soil scraping mechanism 3 and the soil delivery mechanism 4 are installed on the front side of the bucket 2. The soil scraping mechanism 3 scrapes the waste soil to the soil delivery mechanism 4, and the soil delivery mechanism 4 delivers the waste soil into the conveyor belt device 22. In this embodiment, the soil scraping mechanism 3 and the soil delivery mechanism 4 are the same in structure and function as the soil scraping mechanism 3 and the soil delivery mechanism 4 in the existing device (such as patent CN202320669580.8), so they are not repeated here.

[0042] The integrated vehicle of this embodiment further includes a side shield and a top shield, which are used to enclose the bucket 2, the soil digging mechanism 3 and the soil feeding mechanism 4 to prevent dust. The side shield is arranged on the left and right sides of the bucket 2, and includes a horizontal support rod 5 slidably connected to the side of the bucket 2, a driving unit 1 for driving the horizontal support rod 5 to move forward and backward, and a side plate 7 fixed on the horizontal support rod 5; the top shield is arranged on the top of the bucket 2, and includes a horizontal support rod 8 slidably connected to the left and right sides of the top of the bucket 2, a reel 9 located between the two horizontal support rods 8 and rotatably connected to the top surface of the bucket 2, a driving unit 2 for driving the horizontal support rod 8 to move forward and backward, and a driving unit 3 for driving the reel 9 to rotate, and a rolling shutter plate 10 is wound on the reel 9, and the two sides of the rolling shutter plate 10 extending out of the reel part are placed on the horizontal support rods 8 on both sides, such as Figure 4 As shown, the front side of the rolling shutter plate 10 extending out of the winding shaft is provided with an end rod 11 fixed to the horizontal support rods 8 on both sides.

[0043] like Figure 7 and Figure 8As shown, in this embodiment, the driving part includes a servo motor fixed to the side of the bucket 2, a gear 12 rotatably connected to the side of the bucket 2, and a rack 13 arranged on a horizontal support rod 5. The gear 12 and the rack 13 are meshed, and the servo motor drives the gear 12 to rotate, thereby driving the rack 13 to move horizontally forward and backward, and the forward and backward translation of the side plate 7 is realized through the horizontal support rod 5. Preferably, the side panel 7 includes an upper side panel 701 and a lower side panel 702. The upper side panel 701 is fixed to the horizontal support rod 5 and is made of a hard panel. The lower side panel 702 is fixed to the upper side panel 701 and is made of a flexible panel. The hard upper side panel 701 fixes the side panel, and the flexible lower side panel 702 not only prevents dust, but also meets the need for the bucket 2 to move up and down during operation (if the lower side panel 702 also adopts a hard panel, when the bucket 2 moves downward, the hard side panel will contact the ground and be damaged, while the flexible side panel can deform freely, so that the bucket 2 can move unimpeded). The lower side panel 702 of this embodiment can be made of cloth or a flexible rubber panel.

[0044] In this embodiment, the driving part 2 includes a servo motor 2 fixed to the side of the bucket 2, a gear 2 14 rotatably connected to the side of the bucket 2, and a rack 2 15 arranged on the horizontal support rod 2 8. The gear 2 14 and the rack 2 15 are meshed, and the servo motor 2 drives the rack 2 15 to move horizontally forward and backward through the gear 2 14, so as to realize the forward and backward movement of the horizontal support rod 2 8. The reel 9 is also driven by the servo motor to output or retract the rolling shutter plate 10. The end rod 11 is arranged so that the rolling shutter plate 10 and the horizontal support rod 2 8 can move forward and backward synchronously, and prevent the rolling shutter plate 10 from being flipped up. The rolling shutter plate 10 can be made of iron sheet for rolling shutter doors, or thick cloth.

[0045] like Figure 6 As shown, as a preference, a powder hopper 16 is also fixed above the bucket 2 of this embodiment, as shown in FIG. Figure 6 As shown, the bottom of the powder hopper 16 is provided with a material drop opening located between the soil scraping mechanism 3 and the soil feeding mechanism 4, and a quantitative discharging mechanism 17 is provided at the material drop opening, and the quantitative discharging mechanism 17 is used to quantitatively output the powder stored in the powder hopper 16 to the waste soil scraped off by the soil scraping mechanism 3. The quantitative discharging mechanism 17 includes a roller 1701 rotatably connected to the material drop opening, a driving unit 4 for driving the roller 1701 to rotate, and a material storage groove 1702 arranged along the length direction of the roller 1701 is opened on the circumference of the roller 1701. The driving unit 4 adopts a servo motor, and the powder in the powder hopper 16 is a curing agent, which is output downward through the material storage groove 1702. The adjustment of the discharging amount is achieved by adjusting the speed of the roller 1701.

[0046] The use of the integrated vehicle is as follows:

[0047] According to the waste soil pile, the conveyor belt device 22 is adjusted in vertical plane angle, and the bucket 2 ends move upwards, such as Fig.10 As shown in FIG. 1 , the state of scraping the upper waste soil is shown, and the two ends of the bucket move downward. Fig.11 The figure shows the state of scraping the waste soil in the middle, and the two ends of the bucket can continue to move downward, close to the ground, to scrape the waste soil on the ground (not shown in the figure);

[0048] by Fig.11 For example, when shoveling the waste soil in the middle of the soil pile, the mobile base 1 drives the conveyor belt device 22 to move forward to the soil pile, and the end rod 11 and the side plate 7 at the front end touch the soil pile. At this time, each servo motor starts (the start here can be manually judged to start, or it can be automatically controlled by using a sensor to transmit a signal), so that the rolling shutter plate 10 is retracted and the side plate 7 moves to the rear side until the soil-digging mechanism 3 can touch the soil pile; then the soil-digging mechanism 3 is started to dig the soil off, and part of the soil enters the bucket 2 (the soil-digging process is in the area enclosed by the side shielding cover and the top shielding cover). The waste soil is further crushed by the rapid rotation of the soil feeding mechanism 4 during the sweeping process, and the curing agent powder can be fully mixed with the waste soil. The conveyor belt device 22 outputs the crushed and curing agent-mixed waste soil to the rear end (the rear end is generally followed by a soil transport vehicle for real-time soil loading).

[0049] like Fig. 9 As shown, since a plurality of mechanisms are arranged at the front end of the conveyor belt device 22 , there is a phenomenon of top-heavyness. Preferably, in this embodiment, a counterweight 21 is arranged at the discharge port side of the conveyor belt device 22 .

[0050] like Figure 6 and Fig. 9 As shown, the conveyor belt device 22 includes a conveyor belt 2201, side baffles 2202 located on the left and right sides of the conveyor belt 2201, a cover plate 2203 located above the conveyor belt 2201, and two end baffles 2204 located at the front and rear ends of the conveyor belt 2201. The end baffle 2204 is located between the two side baffles 2202 and is rotatably connected to the side plate 7. The end baffle 2204 can swing toward the discharging direction of the conveyor belt 2201; the left and right side baffles 2202, the cover plate 2203, and the front and rear end baffles 2204 form a closed enclosure area with the upper part of the conveyor belt 2201. This can effectively prevent dust from being blown out from the conveyor belt device 22, and further optimize the environment of the factory area.

[0051] like Figure 1 As shown, in this embodiment, a cockpit 6 is further provided on the side of the conveyor belt device 22 to realize manual driving, remote control driving or automatic driving.

[0052] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
