Description

Technical Field

[0001] The present invention relates to the technical field of shot blasting machine trolleys, and more particularly to a trolley-type shot blasting cleaning machine. Background Art

[0002] Trolley-type shot blasting machines, also known as trolley shot blasting machines, are used for surface treatment of large metal workpieces, such as cast iron, forgings, and welds. They remove impurities such as grit, rust, scale, and dirt, restoring the workpiece's original metallic luster. This machine not only provides surface treatment but also eliminates internal stress in the workpiece, improving fatigue resistance and extending its service life. The treated surface of the metal workpiece achieves a certain degree of roughness, which facilitates subsequent paint film adhesion. The machine consists of a shot blasting chamber, trolley, screw conveyor, separator, shot blaster, electrical control box, and dust collector. Workpieces are placed on the trolley, which can be moved and rotated. The shot blaster then activates to strike, achieving rust removal and strengthening. The shot is recycled through the screw conveyor, separator, and dust removal system.

[0003] In actual conditions, the existing trolley only has the functions of moving and rotating when in use, so as to transport the material to the shot blasting machine, and when using steel shots for cleaning, the trolley will rotate autonomously, so that the material can be cleaned more thoroughly. However, the above-mentioned device has a relatively single function when in use. Steel shots are easily accumulated on the existing trolley, causing the steel shots to be carried to the outside, thereby affecting the recovery of the steel shots and wasting certain resources.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 and Figure 2 A trolley-type shot blasting machine includes a trolley arranged in the shot blasting machine. The trolley is composed of a movable base 1, a rotating base 2 and a carrying platform 3. The movable base 1, the rotating base 2 and the carrying platform 3 are installed in sequence from bottom to top. It is particularly noteworthy that the trolley is a part of the shot blasting machine. This is a prior art and will not be described in detail here.

[0032] Reference Figure 1 , a plurality of through holes 4 are provided on the carrying platform 3, among which it is particularly noteworthy that the through holes 4 are located on the upper end surface of the carrying platform 3, so that the steel shots on the carrying platform 3 can enter the material guide seat 6 from the through holes 4, and a plurality of support columns 5 are fixedly connected to the inner bottom of the carrying platform 3, and the upper ends of the plurality of support columns 5 are fixedly connected to the same material guide seat 6, and two symmetrical unloading ports 7 are provided on the carrying platform 3, among which it is particularly noteworthy that the support columns 5 are used to support the material guide seat 6, and the unloading port 7 is located on the output end position side of the material guide seat 6.

[0033] In actual operation, when the steel shot falls from the through hole 4 onto the material guide seat 6, the steel shot can be discharged directly with the assistance of the material guide groove 84 and the discharge port 7, thereby avoiding the accumulation of steel shots on the supporting platform 3, further avoiding the waste of steel shots, and indirectly improving the practicality of the device.

[0034] Reference Figure 3 and Figure 4 An air supply assembly 8 is provided on the material guide seat 6, and the air supply assembly 8 includes an air pump 81 arranged in the material guide seat 6. It is particularly noteworthy that the air pump 81 is a prior art and will not be elaborated here. The output end of the air pump 81 is fixedly connected to a diverter disk 82, and the output end of the diverter disk 82 is fixedly connected to a plurality of bent nozzles 83. A plurality of material guide grooves 84 are provided on the material guide seat 6, and the output ends of the plurality of bent nozzles 83 are respectively located on one side of the input ends of the plurality of material guide grooves 84.

[0035] In actual operation, when the air pump 81 is working, the gas can enter the diverter plate 82, and then the gas is ejected from the bent nozzle 83. Since the bent nozzle 83 is at the input end of the guide trough 84, after the bent nozzle 83 ejects the gas, the air flow can flow along the guide trough 84, thereby accelerating the movement of the steel shot, further preventing the steel shot from remaining on the guide seat 6, and at the same time better allowing the steel shot to return to the recovery system of the shot blasting machine.

[0037] In actual operation, after the gas flows out from the diverter plate 82, the gas will enter the diverter ring 91 from the cross tube 94, and the gas will come from the exhaust head 93. At the same time, since the gas outlet of the exhaust head 93 is on one side of the through hole 4, the gas can flow along the end face of the supporting platform 3, so that the steel shot can further enter the supporting platform 3, further avoiding the loss and waste of the steel shot.
