Description

Technical Field

[0001] This utility model belongs to the field of iron scrap recycling technology, specifically relating to a simple magnetic handcart for automatic iron scrap recycling in steel bar processing plants. Background Technology

[0002] During construction, various structural components made of steel bars are required. These components are all fabricated at the processing site and then transported to the construction site. After the steel bars are processed, the iron filings produced at the processing site are scattered everywhere, which is quite troublesome to clean up. In the traditional process of cleaning iron filings at the processing site, manual cleaning with brooms and dustpans is required. This operation method is complicated, slow, and easy to tire people. It is also impossible to thoroughly clean every corner. Moreover, the iron filings after cleaning contain a lot of impurities and cannot be recycled. They must undergo secondary processing.

[0003] Therefore, we propose to design a simple magnetic handcart for automatic recycling of steel bar processing plant scrap. Utility Model Content

[0004] The purpose of this invention is to provide a simple magnetic handcart for automatic recycling of steel bar processing plant scrap, in order to solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A simple magnetic handcart for automatic recycling of steel scrap in a steel bar processing plant includes a hand-push suction mechanism and a vacuum cleaner. The front end of the vacuum cleaner's suction pipe is connected to the hand-push suction mechanism. The hand-push suction mechanism includes a suction box with an open front and bottom. The top of the suction box has a window, and a flip cover is hinged to the inside of the window near the rear end of the suction box. A magnetic suction mechanism is installed at the bottom of the flip cover.

[0007] Furthermore, a suction connector for connecting to a vacuum pipe is installed at the tail end of the adsorption box; a handle is installed at the middle position of the tail end of the adsorption box.

[0008] Furthermore, the magnetic suction mechanism includes an electromagnetic chuck installed at the bottom of the flip cover, a heat sink installed on the top of the electromagnetic chuck, and a cooling fan installed on the heat sink.

[0009] Furthermore, the flip cover has an air inlet window corresponding to the position of the heat dissipation fan, and the adsorption box has an air outlet window on its side.

[0010] Furthermore, a plastic partition is installed inside the adsorption box at the bottom of the magnetic attraction mechanism, and a front baffle is fixed to the upper edge of the opening at the front end of the adsorption box.

[0011] Furthermore, a control switch is installed at the end of the handle, an electrical wire is connected to the tail end of the vacuum cleaner, and an electrical wire for supplying power to the magnetic suction mechanism is connected between the front end of the vacuum cleaner and the hand-push suction mechanism. The control module of the vacuum cleaner and the control module of the electromagnetic suction cup are both electrically connected to the control switch.

[0012] Furthermore, a cable connects the vacuum cleaner to the suction box, and the cable is wound around the suction tube.

[0013] Furthermore, a pull rod is rotatably mounted near the end of the handle, and a tension spring is connected between the middle of the pull rod near the adsorption box and the handle; a connecting rod is connected between the top of the pull rod and the middle of the flip cover, and both ends of the connecting rod are rotatably connected to the flip cover and the pull rod.

[0014] Furthermore, rear wheels and front wheels are respectively installed on both sides of the tail end and the front end of the adsorption box.

[0015] Beneficial effects:

[0016] This invention utilizes a magnetic adsorption device to highly effectively attract scattered iron filings from the ground. Moreover, it filters out other impurities during the initial collection, effectively preventing the iron filings from being mixed with a large amount of impurities. This allows the iron filings to be directly recycled after collection. At the same time, the combination of the trolley's structural design and the vacuum cleaner makes the process of recycling iron filings on-site more convenient and faster. Throughout the entire recycling process, operators do not need to bend over, saving time and effort. Attached Figure Description

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0024] Example:

[0025] To address the problems of slow, time-consuming, and labor-intensive cleaning of iron filings generated after steel bar processing at current steel bar processing sites, which also fail to thoroughly clean every corner and result in iron filings containing a large amount of impurities that cannot be recycled, we propose the design of a simple magnetic handcart for automatic iron filings collection at steel bar processing sites. The specific design scheme is as follows:

[0026] like Figure 1-5 As shown, this embodiment provides a simple magnetic handcart for automatic recycling of iron filings in a steel bar processing site. Specifically, it includes two parts: a hand-push adsorption mechanism and a vacuum cleaner 5. The front end of the vacuum cleaner 5's suction pipe 4 is connected to the hand-push adsorption mechanism. In order to achieve rapid recycling of iron filings scattered on the site, the hand-push adsorption mechanism includes an adsorption box 1 with an open front end and a bottom. The top of the adsorption box 1 has a window 9, and a flip cover 11 is hinged to the side of the window 9 near the tail end of the adsorption box 1 via a hinge 10. A magnetic adsorption mechanism is installed at the bottom of the flip cover 11 to adsorb iron filings scattered on the ground.

[0027] The tail end of the adsorption box 1 is equipped with a suction connector 3 for connecting to the vacuum pipe 4; and a handle 2 is installed in the middle of the tail end of the adsorption box 1 so that the staff can push the adsorption box 1 back and forth through the handle 2 to adsorb iron filings on the ground using the magnetic suction mechanism, without having to bend over; rear wheels 19 and front wheels 20 are installed on both sides of the tail end and both sides of the front end of the adsorption box 1, respectively.

[0028] In this embodiment, the magnetic attraction mechanism includes an electromagnetic chuck 13 installed at the bottom of the flip cover 11.

[0029] Since the electromagnetic chuck 13 generates heat during the process of generating an electromagnetic field, and the temperature change affects the magnetic properties of the magnetic material and the resistance of the electromagnetic coil, thus affecting the magnetic field strength of the electromagnetic chuck 13, in order to enable the electromagnetic chuck 13 to maintain a stable magnetic field effect for a long time, a heat sink 14 is installed on the top of the electromagnetic chuck 13, and a cooling fan 15 is installed on the heat sink 14. At the same time, an air inlet window 12 is opened on the flip cover 11 corresponding to the position of the cooling fan 15, and an air outlet window 18 is opened on the side of the adsorption box 1.

[0030] To facilitate the smooth falling of iron filings after the magnetic suction mechanism stops working, a plastic partition 17 is installed inside the suction box 1 at the bottom of the magnetic suction mechanism. A front baffle 16 is fixed to the upper edge of the opening at the front of the suction box 1. In this design, by utilizing the structure of the suction box 1, together with the plastic partition 17 and the front baffle 16, an isolation space can be built inside the suction box 1 to prevent iron filings from directly contacting the electromagnetic chuck 13, reducing the possibility of magnetization of the iron filings. This allows the iron filings adsorbed by the electromagnetic chuck 13 to fall down when it stops working and be collected by the vacuum cleaner 5.

[0031] To facilitate the control of the electromagnetic chuck 13 and the vacuum cleaner 5, a control switch 24 is installed at the end of the handle 2, and a power supply wire 6 is connected to the tail end of the vacuum cleaner 5. At the same time, a power supply wire 7 is connected between the front end of the vacuum cleaner 5 and the push suction mechanism to power the magnetic suction mechanism. The control module of the vacuum cleaner 5 and the control module of the electromagnetic chuck 13 are both electrically connected to the control switch 24.

[0032] To prevent the suction hose 4 from falling off during the pulling process, a pull cable 8 is connected between the vacuum cleaner 5 and the suction box 1, and the pull cable 8 is wrapped around the suction hose 4.

[0033] In addition, depending on the requirements, its magnetic attraction mechanism can also be composed of several powerful neodymium boron magnets. Several powerful neodymium boron magnets are fixed on the flip cover 11 to form a constant magnetic field at the top of the adsorption box 1. On this basis, in order to facilitate the collection of iron filings after adsorption, a pull rod 21 is rotatably installed near the end of the handle 2. A tension spring 22 is connected between the middle of the pull rod 21 near the adsorption box 1 and the handle 2. A connecting rod 23 is connected between the pull rod 21 near the top and the middle of the flip cover 11. Both ends of the connecting rod 23 are rotatably connected to the flip cover 11 and the pull rod 21.

[0034] By pulling the lever 21, the flip cover 11 is flipped around the hinge 10, which moves the magnetic mechanism away from the plastic partition 17, causing the iron filings to break free from the magnetic field and fall from the bottom of the plastic partition 17. At the same time, the vacuum cleaner 5 starts working to pick up and collect the falling iron filings.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
