[0017] like Figure 1-2 The utility model provides a vehicle-mounted metal foreign body adsorption device, comprising a mounting frame 2 arranged vertically and slidingly in front of a wheel, a cage-shaped adsorption cage arranged horizontally and rotatably below the mounting frame 2, and a contact piece 6 fixed to the bottom of a support shaft 5 of the adsorption cage, the contact piece 6 contacts an adsorption rod 9 on the circumference of the adsorption cage, a coil is spirally wound on the adsorption rod 9, the contact piece 6 is located at both ends of the adsorption rod 9 and is electrically connected to the coil on the adsorption rod 9, a collecting tank 10 is provided at the bottom of the mounting frame 2, and the collecting tank 10 is located between the adsorption cage and the wheel.

[0018] The bottom of the adsorption cage is supported by the ground. During the operation of the underground vehicle, the adsorption cage rolls, and the magnetic field generated by the energized coil on the adsorption rod 9 is used to adsorb metal foreign matter on the road surface. The adsorbed metal foreign matter rotates with the rolling of the adsorption cage; the contact piece 6 is connected to a DC power supply. Since the contact piece 6 is located at the inner bottom of the adsorption cage, the contact piece 6 only contacts the adsorption rod 9 at the bottom of the adsorption cage and energizes the coil on the contacted adsorption rod 9. After the adsorption rod 9 rotates upward and loses contact with the contact piece 6, the adsorbed metal foreign matter on the adsorption rod 9 falls into the collection trough 10, completing the collection of the metal foreign matter.

[0019] The liftable mounting frame 2 can maintain contact with the ground during the driving of the vehicle and is not easily damaged by collision on rough roads.

[0020] like Figure 1 As shown. A lifting seat 3 is fixedly arranged on the top of the mounting frame 2, and a supporting frame 1 is fixedly arranged on the bottom of the vehicle chassis. The bottom of the lifting seat 3 is vertically slidably arranged on the supporting frame 1. A spring is sleeved on the top of the lifting seat 3, and the two ends of the spring are respectively connected to the top of the lifting seat 3 and the top surface of the supporting frame 1. The mounting frame 2 relies on its own weight to keep the bottom of the adsorption cage in contact with the ground, and the spring is used for auxiliary support to reduce friction.

[0021] like Figure 1 and Figure 2 As shown, in order to realize the protection of the contact piece 6. The bottom of the mounting frame 2 is fixedly provided with a mounting ear plate, the support shaft 5 is fixedly connected to the bottom end of the mounting ear plate, the adsorption cage is coaxially connected to the support shaft 5, and the contact piece 6 is located inside the adsorption cage. The contact piece 6 is arranged inside the adsorption cage, and the contact piece 6 is connected to a DC power supply. When the contact piece 6 is connected at both ends of the adsorption rod 9, the coil on the adsorption rod 9 is turned on.

[0022] like Figure 1 and Figure 2 As shown. The adsorption cage includes the adsorption rod 9, the mounting plate 8 fixedly connected to the end of the adsorption rod 9, the mounting rod 7 rotatably connected to the movable end of the mounting plate 8, and the mounting plate 4 fixedly connected to the movable end of the mounting rod 7. The mounting plate 4 is coaxially rotatably connected to the support shaft 5, and the mounting rod 7 is arranged at equal angles around the axis of the mounting plate 4. The mounting plate 4 condenses the support shaft 5 through a bearing. When the adsorption rod 9 contacts a protruding stone, the stone will push the adsorption rod 9, so that the adsorption rod 9 drives the mounting plate 8 to rotate around the mounting rod 7, thereby ensuring the safety of the adsorption rod 9.

[0023] like Figure 1 , Figure 2 and Figure 3As shown. The mounting rod 7 is located between the axis of the support shaft 5 and the adsorption rod 9, the contact piece 6 is arc-shaped, and an arc-shaped strip for electrical connection is provided in the middle of the contact piece 6, and the arc-shaped strip contacts the outer side wall of the mounting rod 7. The adsorption rod 9, the mounting piece 8 and the mounting rod 7 all adopt a hollow structure, and the arc-shaped strip contacts the contact point on the peripheral surface of the end of the mounting rod 7. The mounting piece 8 is provided with a connecting wire connecting the contact point on the peripheral surface of the end of the mounting rod 7 and the coil on the adsorption rod 9, and the surface of the mounting piece 8 and the adsorption rod 9 are not charged.

[0024] like Figure 1 As shown. The bottom end of the collecting trough 10 is arc-shaped, a gap is provided between the collecting trough 10 and the adsorption cage, an opening is provided on the side wall of the collecting trough 10 facing the adsorption cage, and a permanent magnet sheet 11 is provided on the side wall of the collecting trough 10 away from the adsorption cage. The permanent magnet sheet 11 adsorbs the metal foreign matter falling into the collecting trough 10, so as to prevent the metal foreign matter in the collecting trough 10 from falling due to vibration during the operation of the vehicle.

[0025] like Figure 1 The bottom of the collecting tank 10 is hinged with a discharge plate 12, and the movable end of the discharge plate 12 is connected to the side wall of the collecting tank 10 through a pin shaft. When the collecting tank 10 needs to be cleaned, the movable end of the discharge plate 12 is turned down by pulling out the pin shaft, and the discharge plate 12 is in a vertical state, and the metal foreign matter in the collecting tank 10 is scraped off by the scraper to complete the cleaning of the metal foreign matter.
