Description

Technical Field

[0001] The invention relates to the technical fields of mechanical engineering and building steel structure engineering, and in particular to a magnetic steel shot recovery trolley. Background Art

[0002] In a steel structure manufacturing plant, one of the most important processes is to perform anti-corrosion treatment on steel plates or steel components, that is, to remove rust from the surface of steel plates or steel components, and then spray paint. The equipment used in the rust removal process is mainly a shot blasting machine. The working principle of the shot blasting machine is to use the high-speed rotation of the motor to shoot steel shots at high speed through the blades. The steel shots hit the steel plate at a speed of 70-90 meters per second to achieve the purpose of removing rust from the surface of the steel plate. Therefore, in actual work, there will be more steel shots shot out from the inlet and outlet ends of the shot blasting machine, flying to the ground around the shot blasting machine, and the scattered area is large. This part of the steel shots is difficult to recycle, and generally can only be directly swept as garbage, which takes a long time to clean up and there is a large cost waste. Moreover, if the steel shots are left scattered on the site without being cleaned up in time, it will be a greater safety risk for the subsequent processing process. Summary of the invention

[0023] The following is combined with Figure 1-Figure 7 The specific implementation manner of a magnetic steel shot recovery trolley of the present invention is further described in detail.

[0024] A magnetic steel shot recovery trolley is provided with a magnetic module, a recovery disk and a roller brush device in a shell, and the recovery disk and the roller brush device are driven to rotate by the rotation of the wheel, so that the spilled steel shots can be recovered quickly and conveniently. The trolley specifically includes the following parts:

[0025] 1. Shell: The shell is made of aluminum alloy and is divided into a chassis 100, an intermediate support layer 101, and an upper cover 102. The chassis is a square box with a semi-circular opening in the middle, which plays the main rigid support role and carries the rest of the components. The protruding guard plate on it divides the functional area. The intermediate support layer is mainly used to fix the magnetic module 200 and the push rod 900. The upper cover 102 is located at the top layer to protect and shield the internal structure. The rear cover also serves as a slideway for steel shots.

[0026] 2. Magnetic module: The magnetic module 200 is a semi-annular permanent magnet fixed to the middle support layer 101 and is responsible for generating a magnetic field to exert an upward magnetic force on the steel shot on the ground.

[0027] 3. Recovery plate: The recovery plate 300 is an aluminum alloy disc, which is connected to the upper belt transmission wheel through the rotating shaft 301. There is a leather arc banner 302 at the bottom of the recovery plate, which is responsible for collecting the steel balls adsorbed from the ground and transporting them to the roller brush device.

[0028] 4. Roller brush device: The roller brush device is located behind the recovery plate 300. The main body is made of PE plastic and has multiple plastic brushes 401 attached to it. The whole is connected to the side belt conveyor wheel through a steel shaft. It is responsible for throwing the steel balls conveyed from the recovery plate to the rear and upward.

[0029] 5. Belt drive wheel group: The belt drive wheel group is divided into two groups, the front and rear groups. The front group 500-502 converts the rotation of the gear group into the rotation of the recovery plate, and the rear group 503-505 is responsible for converting the rotation of the rear wheel group into the rotation of the roller brush device.

[0030] 6. Gear set: Bevel gear 600 is fixed to the front axle, and the rotation direction is converted through transition gear 601. Transition gear 601 and transition bevel gear 602 are fixed on the same steel shaft, and driven gear 603 is coaxial with pulley 500, which finally converts the rotation of the wheel into the rotation of the front pulley set.

[0031] 7. Wheel set: The front and rear wheel sets 700-701 are all polyurethane tires with steel axles. The tires are connected by axles, placed on the chassis 100, and in direct contact with the ground, which eventually converts part of the human thrust into forward power, and the other part drives the gear set and the belt transmission wheel set to rotate, providing power for the transportation of steel shots.

[0032] 8. Collection basket: The collection baskets 800-801 are located on both sides of the roller brush device. After being driven by the roller brush device, the steel shots roll out from the outlet and fall into the collection basket through the ramp. When the collection basket is full, the collection basket can be directly lifted out by pulling the handle to collect the steel shots uniformly.

[0033] 9. Push rod: One end of the push rod 900 is a horizontal bar for people to hold, and the other end is connected to the trolley shell through an inclined wedge.

[0034] The specific working implementation method of the present invention is as follows:

[0035] 1. Place the four-wheel vehicle flat on the ground where the steel shots are scattered, and the operator holds the crossbar of the push rod 900 and pushes it forward.

[0036] 2. During the forward push, the chassis 100 sweeps across the ground. When the steel shot passes through the slotted position of the semi-circular feeding hole of the chassis, it is closest to the magnetic module 200. The magnetic attraction received is large enough to overcome gravity and is adsorbed on the surface of the recovery plate 300.

[0037] 3. While moving forward, the rotation of the wheel drives the recovery plate 300 to rotate through the gear set and the belt drive wheel set, and the steel shots adsorbed on the surface of the recovery plate rotate accordingly.

[0038] 4. Since the magnetic module is fixed, the steel shot leaves the slotted area of ​​the chassis and gradually moves away from the magnetic module as the recovery plate rotates, and the steel shot falls on the surface of the chassis.

[0039] 5. The steel shot falling on the surface of the chassis is then swept by the leather arc banner 302 on the recovery plate, and is concentrated along the arc of the banner to the edge of the recovery plate until the steel shot passes through the roller brush device area and is squeezed out from the designed gap.

[0040] 6. The roller brush device is connected to the rear wheel group through a belt drive group, so the roller brush device also rotates synchronously during the forward movement. The steel shot squeezed out from the gap is driven by the brush on the roller brush device and continues to move on the ramp.

[0041] 7. After the steel shot is brought to the top, it rolls out smoothly from the exit without the obstruction of the ramp and falls into the collection basket through the ramp.

[0042] 8. As the trolley moves forward, the steel shots on the ground are continuously collected. When the collection basket is full, the collection basket is directly lifted out, the steel shots are poured out from the corner and stored uniformly, and the empty collection basket is put back to continue working.

[0043] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.

[0044] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as within the scope of protection of the present invention.
