Description

Technical Field

[0001] The utility model relates to the technical field of steel shot recovery devices, in particular to a hand-push type steel shot recovery vehicle. Background Art

[0002] Shot blasting machine is a common surface treatment equipment in the steel structure industry. It is mainly used for metal surface cleaning, rust removal and stress relief. Steel shot is the main raw material of the shot blasting machine. During actual operation, a large number of steel shots will fly out from the inlet and outlet ends of the shot blasting machine and scatter to the surrounding area of ​​the shot blasting machine. The scattering area is large, which will cause great waste. The scattered steel shots usually need to be manually cleaned and collected. Due to the limitations of the processing environment, the cleaned and collected steel shots will be mixed with a lot of dust, garbage, etc. Therefore, the cleaned and collected steel shots need to be screened. Since the steel shots themselves are heavy, relying on manual collection and screening is not only inefficient but also labor-intensive.

[0003] At present, there are also some steel shot recovery devices, such as patent number CN201020126160.8, and the patent name is a Chinese utility model patent for a steel shot recovery vehicle. The device is mainly composed of a chassis, a collection box, a magnet roller, a running wheel and an armrest. The chassis is either frame-type or flat-plate-shaped; the magnet roller is located between the chassis, dividing the chassis into a front chassis and a rear chassis; the collection box is connected to the bottom of the front chassis; the running wheel is installed under the rear chassis; the bottom ends of the armrest are connected to the rear cross brace of the rear chassis. Although the above device can realize the recovery of steel shots scattered on the ground, it is unable to effectively separate the broken steel shots, steel shot debris and steel ash during the recovery process, and workers are still required to perform secondary separation. The work efficiency and recovery quality need to be improved. Utility Model Content

By setting the scraper 9, during the rolling process of the drum 5, the scraper 9 will scrape off the steel shots, steel shot debris and steel ash adsorbed on the surface of the drum 5, and drop them into the aggregate screen bucket 8. The steel shots, steel shot debris and steel ash are collected and screened by the aggregate screen bucket 8, and the qualified steel shots are located at the upper part of the aggregate screen bucket 8, while the steel shot debris and steel ash are screened to the bottom of the aggregate screen bucket 8. Thus, through the above-mentioned device, the steel shots scattered on the ground are effectively recovered, and the recovered steel shots and waste can be effectively separated without manual secondary screening, thereby improving work efficiency and recovery quality.

[0035] Combine Figure 1-Figure 3 As shown, the aggregate screen hopper 8 includes an aggregate hopper 801, and hanging plates 802 are connected to both sides of the aggregate hopper 801. The hanging plates 802 are hung on the vehicle frame 1. By setting the hanging plates 802, the aggregate screen hopper 8 is easily placed on the vehicle frame 1. A screen hopper 803 is installed on the aggregate hopper 801, and a hanging portion 804 is provided on the screen hopper 803. The screen hopper 803 is suspended on the aggregate hopper 801 through the hanging portion 804. In this embodiment, two hanging portions 804 are relatively arranged.

[0036] Combine Figure 1-Figure 3 As shown, handles 805 are respectively installed on the hanging plates 802, and the handles 805 are provided to facilitate taking and placing the aggregate sieve 8 on the frame 1;

[0037] The side of the screen bucket 803 close to the drum 5 and the bottom of the screen bucket 803 are densely covered with a number of screen holes 806. The screen holes 806 are arranged to facilitate screening of steel shots and waste materials, so that steel shot fragments and steel ash fall through the screen holes 806 and fall onto the collecting hopper 801.

[0038] Combine Figure 1-Figure 3 As shown, the hanging portion 804 is arranged in a U-shaped structure and is clamped on the side wall of the collecting hopper 801. By designing the hanging portion 804 into a U-shaped structure, the screening bucket 803 is fixed on the collecting hopper 801 more firmly.

[0039] Combine Figure 4-Figure 6 As shown, the magnet mounting frame 6 includes a magnet mounting sleeve 601, which is sleeved in the sleeve and has a gap with the sleeve. A number of magnet mounting grooves 602 are arranged on the outer wall of the magnet mounting sleeve 601, and a number of permanent magnets 7 are respectively installed in the magnet mounting grooves 602. The inner wall of the magnet mounting sleeve 601 is fixedly connected to the support shaft 3 through a number of connecting rods 603. By providing the magnet mounting sleeve 601 and the magnet mounting grooves 602, the installation and fixation of the permanent magnets 7 are facilitated.

[0040] Combine Figure 4 As shown, connecting plates 10 are respectively provided at both ends of the roller 5 in the axial direction. The connecting plate 10 is connected to the support beam of the wheel 4 through a connecting member 11. The connecting member 11 is arranged in a U-shaped structure, and connecting holes are respectively provided at both ends of the U-shaped structure of the connecting member 11. Bolts are passed through the connecting holes. The roller 5 is connected to the wheel 4 through the connecting plate 10 and the bolts.

[0041] Combine Figure 5-Figure 6 As shown, a plurality of permanent magnets 7 are arranged in an arc structure along the side of the magnet mounting frame 6 away from the aggregate screen bucket 8. By arranging the permanent magnets 7 in an arc structure along the side of the magnet mounting frame 6 away from the aggregate screen bucket 8, the bottom of the drum 5 and the stroke from the bottom to the top are magnetic, and the drum 5 can absorb steel shots, steel shot debris and steel ash. However, in the stroke from the top of the drum 5 to the scraper 9, no permanent magnets 7 are provided, so the magnetism of the drum 5 is weak, which facilitates the scraper 9 to scrape the steel shots, steel shot debris and steel ash attached to the drum 5 into the aggregate screen bucket 8.

[0042] Combine Figure 1 As shown, the diameter of the roller 5 is smaller than the diameter of the wheel 4, so that the roller 5 can be at a certain distance from the ground, which is convenient for adsorbing the steel shot.

[0043] For ease of understanding, the working process of this embodiment is given below:

[0044] Combine Figures 1-6As shown, first, the frame 1 is pushed to move by the hand push handle 2. During the movement of the frame 1, the wheel 4 drives the roller 5 to rotate synchronously. Since the inner cavity of the roller 5 is provided with a magnet mounting frame 6, the magnet mounting frame 6 is fixedly mounted on the support shaft 3. A plurality of permanent magnets 7 are arranged on the magnet mounting frame 6. The plurality of permanent magnets 7 are arranged close to the inner wall of the roller 5. Thus, the roller 5 has a certain magnetism through the permanent magnets 7. During the rolling process of the wheel 4, the steel shots, steel shot debris and steel ash scattered on the ground will be adsorbed on the surface of the roller 5 and rotate with the roller 5. When the roller 5 rotates to When the scraper 9 is in place, the scraper 9 will scrape off the steel shots, steel shot debris and steel ash adsorbed on the surface of the drum 5 and drop them into the aggregate screen hopper 8. Since the aggregate screen hopper 8 includes the aggregate hopper 801 and the screen hopper 803, when the steel shots, steel shot debris and steel ash fall into the aggregate screen hopper 8, the screen hopper 803 screens the steel shots and waste materials scraped off by the scraper 9, so that the qualified steel shots remain in the screen hopper 803 and are reused, while the screened steel shot debris and steel ash fall into the aggregate hopper 801 below and are recycled and recast, thereby realizing the recovery and screening of the steel shots, which is easy to operate and has high work efficiency.

[0045] In summary, the utility model provides a hand-push steel shot recycling vehicle, which can effectively recycle steel shots scattered on the ground, and can effectively separate the recycled steel shots and waste materials without the need for manual secondary screening, thereby improving work efficiency and recycling quality.
