[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0023] Example: See Figure 1-3 The present invention provides a technical solution: a large-diameter weather-resistant and high-strength fastener heat treatment equipment, including a box body 1, a sealing cover 7 is connected to the top of the box body 1, a water inlet pipe groove 8 is opened on the top of the sealing cover 7, a water inlet pipe 9 is provided in the inner cavity of the water inlet pipe groove 8, and a nozzle 10 is connected to the bottom of the water inlet pipe 9, a support rod 2 is connected to one side of the box body 1, one end of the support rod 2 is connected to the side plate 3, a roller 4 is connected between the two side plates 3, the outer ring of the roller 4 is sleeved with a belt 5, one end of the roller 4 is connected to a motor 6, the inner cavity of the box body 1 is connected to a connecting rod 12, one end of the connecting rod 12 is connected to a slide rail 13, one end of the slide rail 13 is connected to a material gathering plate 14, the bottom of the slide rail 13 is connected to a limiting rod 15, and a material inlet trough 16 is opened on the top of one end of the sealing cover 7.

[0024] Among them, the feeding trough 16 is opened above the belt 5, the material of the belt 5 is stainless steel, the bottom of the material collecting plate 14 and the slide rail 13 is close to the top of the belt 5, and the material collecting plate 14 and the slide rail 13 are Y-shaped at the top of the belt 5.

[0025] In this embodiment, when in use, the heated bolt workpiece is put into the upper part of the belt 5 through the feeding trough 16, and then the motor 6 drives the belt 5 to rotate through the roller 4. The workpiece is forced to move on the surface of the belt 5 and moves along the side of the gathering plate 14 when it contacts the gathering plate 14. Figure 5 It can be seen intuitively that the closer the gathering plate 14 is to the slide rail 13, the shorter the distance between the two gathering plates 14 is, thereby avoiding the occurrence of workpieces being piled up or side by side. When the front workpiece is pushed to the top of the slide rail 13 by the subsequent workpiece, the workpiece will slide along the top of the slide rail 13. At the same time, the water inlet pipe 9 sprays external water on the surface of the workpiece through the nozzle 10, thereby achieving quenching of the workpiece. Figure 5 It can be intuitively understood that the distance between the two slide rails 13 is significantly longer than the distance between the two limit rods 15. This setting takes into account the characteristics of the bolt workpiece with a large head and a small body. When the workpiece reaches between the two slide rails 13, the bottom of the bolt loses support and falls downward until the threaded column of the bolt falls between the two limit rods 13. At this time, the bolt head is limited by the top of the two limit rods 15, thereby utilizing the characteristics of the workpiece itself to a certain extent to ensure the safety of the workpiece during transportation.

[0026] Among them, a slot 17 is opened on one side of the box body 1, and the inner cavity of the slot 17 is movably connected with a card block 18, one end of the card block 18 is connected to a filter plate 19, and a plurality of filter holes 20 are opened through the top of the filter plate 19. The other end of the card block 18 is connected to a T-shaped pull block 30, and the inner cavity of the box body 1 is provided with a fixed plate 21, and the fixed plate 21 is located below the filter plate 19.

[0027] In this embodiment, the slot 17 is located below the slide rail 13, and the filter plate 19 is used to support the bottom of the workpiece, so as to prevent some workpieces from sliding down to an odd position and being washed away by water during quenching. When in use, the filter plate 19 can be pulled out of the slot 17 through the U-shaped handle 26 to remove the scattered workpieces, and the fixing plate 21 places the filter plate 19 in the inner cavity of the box body 1.

[0028] A drainage pipe groove 28 is provided at the bottom of one side of the box body 1 , and a drainage pipe 29 is provided in the inner cavity of the drainage pipe groove 28 .

[0029] In this embodiment, the drainage pipe groove 28 and the drainage pipe 29 are used to discharge and collect the water sprayed by the nozzle 10. After treatment, the resource can be recycled.

[0030] Among them, a discharge chute 27 is opened on one side of the box body 1, and multiple L-shaped limit plates 23 are connected to the bottom of one side of the box body 1. A material collection box 24 is movably connected between the two L-shaped limit plates 23. A material feed port 22 is opened on one side of the material collection box 24. The material feed port 22 and the discharge chute 27 are on the same horizontal line. The top of the material collection box 24 is magnetically connected to a cover plate 25, and the top of the cover plate 25 is connected to a U-shaped handle 26.

[0031] In this embodiment, after the workpiece slides down the slide rail 13 , it is discharged from the device through the discharge chute 27 and then enters the inner cavity of the collection box 24 through the feed port 22 , thereby being collected.

[0032] The bottom of the cover 7 is connected to a sensor 11 , which is electrically connected to the nozzle 10 . The sensor 11 is an infrared sensor, and is located above the slide rail 13 .

[0033] In this embodiment, the sensor 11 is used to sense the movement of the workpiece, and when the workpiece reaches below the sensor 11, the workpiece is quenched by the nozzle 10, thereby avoiding unnecessary waste of resources.

[0034] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
