Description

Technical Field

[0001] The utility model belongs to the technical field of shot blasting machines, and specifically relates to a mesh belt passing type shot blasting machine. Background Art

[0002] Mesh belt shot blasting machine refers to a machine that removes scale, cleans and pre-treats various steel materials such as steel plates, steel, steel beams, steel sections, steel pipes and steel castings in a continuous passing manner. It is suitable for sand removal, rust removal, scale removal and surface strengthening of small castings, forgings, stampings, gears, springs and other parts, and is especially suitable for cleaning and strengthening of parts that are not afraid of collision.

[0003] The shot-residue mixture that falls into the collecting trough after shot blasting also contains a large amount of metal oxide scale fragments, broken projectiles, dust and other debris, and the existing mesh-belt shot blasting machines generally adopt waterfall screening. However, when using waterfall screening, the contact area between the shot-residue mixture and the screening structure is limited, which will lead to incomplete screening, thereby reducing the cleaning effect of the mesh-belt shot blasting machine, causing the cleaning effect of the steel shot to gradually decrease during the circulation process, affecting the cleaning efficiency of the shot blasting machine.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-6 As shown, a mesh belt passing shot blasting machine comprises a shot blasting machine body 1, a collecting bucket 2 is arranged at the lower side of the shot blasting machine body 1, a lifting device is arranged at the rear side of the collecting bucket 2, and a screening device is arranged at the front side of the shot blasting machine body 1;

[0025] The lifting equipment includes a bucket elevator 3, a temporary storage box 4 is provided on the upper side of the bucket elevator 3, and a conveying component is connected to the front side of the temporary storage box 4;

[0026] The transmission assembly is connected with the screening equipment, and the screening equipment includes a shell 5, a spiral slide 6 is installed on the inner side of the shell 5, and a plurality of evenly distributed sliding sleeves 7 are vertically fixedly installed on the side of the spiral slide. A fixed rod 8 is slidably connected to the lower side of the sliding sleeve 7, and the lower side of the fixed rod 8 is fixedly connected to the shot blasting machine body 1. A spiral screen plate 9 is installed in the middle of the spiral slide 6, and a plurality of screen holes 10 are evenly opened on the upper side of the spiral screen plate 9. A steel shot bucket 11 is fixed at the lower end of the spiral slide 6. The steel shot bucket 11 is located on the upper side of the lower end of the spiral screen plate 9 and matches the spiral screen plate 9 and the spiral slide 6. An arc-shaped baffle 12 is installed on the lower side of the steel shot bucket 11. A steel shot box 13 fixedly connected to the shot blasting machine body 1 is installed at intervals on the lower side of the steel shot bucket 11, and the steel shot box 13 is located on the right side of the baffle. The upper side of the spiral slide 6 is also connected to the transmission assembly.

[0027] When the shot blasting machine body 1 is working, the processed shot-slag mixture falls into the inner side of the collecting bucket 2 on the lower side of the shot blasting machine body 1 together, and is transmitted to the inner side of the temporary storage box 4 through the bucket elevator 3. The bucket elevator 3 is a continuous conveying machine, which uses a hopper fixed to a traction chain or a belt to transport bulk materials upward in a vertical or nearly vertical direction. The conveying component can transmit the shot-slag mixture inside the temporary storage box 4 downward to the upper side of the spiral slide 6, and fine dust and broken projectiles flow into the lower side of the spiral screen plate 9 through the sieve holes 10 on the upper side of the spiral screen plate 9. The intact steel shots slide down from the upper side of the arc screen plate to the steel shot bucket 11 and finally fall into the steel shot box 13. The steel shot box 13 is connected to the shot blasting machine pipeline inside the shot blasting machine body 1, and the steel shots can be recycled. The transmission component can make the arc slide shake up and down as a whole.

[0028] The design of the spiral slide 6 and the spiral screen plate 9 increases the contact area between the shot-slag mixture and the screening equipment, and increases the screening time of the shot-slag screening equipment on the shot-slag mixture, so that the shot-slag mixture can be screened more thoroughly, the cleanliness of the steel shots is improved, and the cleaning efficiency of the shot blasting machine is ensured. The arc baffle 12 can prevent the screened waste slag from entering the steel shot box 13, and the transmission assembly can make the spiral slide 6 shake up and down as a whole, which increases the flow rate when the shot-slag mixture is screened and improves the screening efficiency.

[0029] The transmission assembly includes a motor 14, which is installed on the upper side of the outer shell 5. A crank 15 is rotatably installed on the upper side of the inner part of the outer shell 5. The crank 15 is transmission-connected to the output end of the motor 14. A connecting rod 16 is installed on the lower side of the crank 15. One end of the connecting rod 16 is hinged to the crank 15 and is eccentric to the axis of the motor 14. The other end of the connecting rod 16 is hinged to the spiral slide 6.

[0030] When the transmission assembly is working, the output end of the motor 14 drives the crank 15 to rotate, and the connecting rod 16 converts the cylindrical motion of the crank 15 into an up and down reciprocating motion of the spiral slide 6. The cooperation between the crank 15 and the connecting rod 16 ensures the operation of the transmission assembly while making the structure of the transmission assembly simple and reliable, reducing the failure rate and facilitating maintenance.

[0031] The transmission assembly includes a transmission tube 17, one end of which is connected to the temporary storage box 4, and the other end of the transmission tube 17 is located on the upper side of the spiral slide 6. An auger 18 is rotatably installed on the inner side of the transmission tube 17, and a first pulley 19 is concentrically fixed to the right side of the auger 18. A second pulley 20 concentrically fixed to the output end of the motor 14 is rotatably installed on the upper side of the first pulley 19, and a belt 21 is connected to the first pulley 19 and the second pulley 20 for transmission.

[0032] When the conveying component is working, the auger 18 cooperates with the transmission pipe 17 to transfer the ball-residue mixture inside the temporary storage box 4 to the upper side of the spiral slide 6. The cooperation of the first pulley 19, the second pulley 20 and the belt 21 enables the conveying equipment and the transmission component to work in conjunction and share the power source, thereby improving the overall utilization rate of the motor 14.

[0033] An ash collecting hopper 22 is installed at the lower side of the housing 5. A square groove is provided at the lower side of the ash collecting hopper 22. An ash collecting hopper 23 matching with the ash collecting hopper 23 is installed inside the square groove so as to slide back and forth.

[0034] The ash collecting hopper 22 is used to collect debris such as metal oxide scale fragments, broken projectiles, dust, etc. that fall from the upper side, and the ash collecting hopper 23 is convenient for cleaning them.

[0035] A spring 24 is connected to the lower side of the spiral slideway 6 , and the other end of the spring 24 abuts against the shot blasting machine body 1 .

[0036] The spring 24 can continuously provide elastic force upward, thereby neutralizing the gravity of the spiral slideway 6 and the ball-residue mixture, reducing the workload of the transmission component, saving energy consumption and extending its service life.

[0037] An inspection opening is provided at the front side of the housing 5 , and an inspection door 25 is installed at the front side of the inspection opening.

[0038] The inspection door 25 can be opened, so that technicians can conveniently clean or maintain the inside of the screening device to ensure the normal operation of the screening device.
