For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Figure 1 , Figure 2 and Figure 3 The shown embodiment is a self-propelled screening material conveying device for fastening connecting parts, comprising a main frame 1 and a bottom base 2, a self-propelled driving wheel 3 is installed on the outer side of the bottom base 2, an electrically controlled lifting mechanism 4 is arranged between the upper surface of the bottom base 2 and the lower surface of the main frame 1, a combined electrically controlled feeding device 5 is movably assembled inside the main frame 1, a bottom feeding belt 6 is installed inside the main frame 1 below the combined electrically controlled feeding device 5, and a circulating external feeding return device 7 is installed on the outer side of the main frame 1.

[0029] In order to cooperate with the lifting and lowering adjustment, the electrically controlled lifting mechanism 4 includes a first electrically controlled support rod 41 and a second electrically controlled support rod 42 installed between the upper surface of the bottom base 2 and the lower surface of the main frame 1. The first electrically controlled support rod 41 and the second electrically controlled support rod 42 are respectively staggered and arranged on both sides of the bottom conveyor belt 6.

[0030] In order to cooperate with the adjustment control, the combined electric-controlled feeding device 5 includes a first feeding frame 51, a second feeding frame 52, a third feeding frame 53, a fourth feeding frame 54 arranged in parallel, an overhead electric-controlled screw rod 55 fixed on both sides of the main frame 1, a first electric-controlled translation support rod 56, a second electric-controlled translation support rod 57 and a side electric-controlled rotating seat 58.

[0031] Working principle: The first electric control support rod 41 and the second electric control support rod 42 are extended to control the main frame 1 to be lifted to the unloading end, and then the connecting piece is fastened to unload the material onto the combined electric control feeding device 5. During the conveying process, the first feeding frame 51 and the fourth feeding frame 54 are translated outward to adjust the gap between the first feeding frame 51 and the second feeding frame 52 and the gap between the third feeding frame 53 and the fourth feeding frame 54. Then, the first feeding frame 51, the second feeding frame 52, the third feeding frame 53, and the fourth feeding frame 54 are turned over to each other. A screening mechanism with an inclination is formed between the first feeding frame 51 and the second feeding frame 52 and between the third feeding frame 53 and the fourth feeding frame 54, so that the fastening connectors will screen the materials synchronously during the conveying process, and then the fastening connectors that have fallen will fall onto the bottom feeding belt 6, and the materials that have not been screened will be redirected back to the loading port through the circulating external returning device 7, screened again, and after the second screening, the screening gap will be enlarged again, and then the above operations will be repeated to complete the screening operation.

[0032] In order to cooperate with driving and adjustment, the first feed frame 51, the second feed frame 52, the third feed frame 53 and the fourth feed frame 54 are all composed of a horizontal translation frame 8, a horizontal material guide frame 9 installed inside the horizontal translation frame 8 and an electrically controlled conveyor belt 10 movably assembled inside the horizontal material guide frame 9.

[0033] The electric-controlled conveyor belt 10 drives the fastening connectors on the upper surface to be transported horizontally through operation.

[0034] In order to cooperate with translation adjustment, the outer sides of the first feeding frame 51 and the fourth feeding frame 52 are both sleeved on the top electric control screw rod 55 through the side internal thread translation block 11 and are threadedly assembled with the top electric control screw rod 55.

[0035] In order to facilitate installation and adjustment, the first electrically controlled translation support rod 56 is fixedly installed at the bottom of the first feed frame 51, the second electrically controlled translation support rod 57 is fixedly installed at the bottom of the fourth feed frame 54, and the side electrically controlled rotating seat 58 is installed between the transverse translation frame 8 and the transverse material guide frame 9.

[0036] The transverse material guide frame 9 is inserted into the side electrically controlled rotating seat 58 through the outer assembly shaft and is axially connected to the worm gear inside the side electrically controlled rotating seat 58. The worm gear is meshed with the internal electrically controlled worm, and the rotation is controlled by the electrically controlled worm.

[0037] The extended end of the first electrically-controlled translation support rod 56 is fixedly assembled with the second material conveying frame 52 , and the extended end of the second electrically-controlled translation support rod 57 is fixedly assembled with the third material conveying frame 53 .

[0038] In order to cooperate with the electric control adjustment, the circulating external material return device 7 includes an external guide rail 71 fixedly installed on the outside of the main frame 1, an electric drive gear 72 movably installed on the inside of the external guide rail 71, an external material guide belt 73 sleeved on the outside of the electric drive gear 72, an external limit baffle 74 installed on the side wall of the external material guide belt 73 and an electric control limit frame 75 movably installed on the side wall of the external guide rail 71.

[0039] The electric drive gear 72 controls the operation of the external material guide belt 73 by rotating, and then the external material guide belt 73 drives the external limit baffle 74 to operate, so that the fastening connector drops from the output end of the combined electric control feeding device 5, and then transfers along the external guide rail 71 to the input end of the combined electric control feeding device 5 and drops again, and uses the electric control limit frame 75 to accurately guide the fastening connector of the recycled material to the screening port position for secondary or multiple screening.

[0040] The outer guide rail 71 is arranged obliquely to facilitate the circulation of materials. The electric control limit frame 75 is composed of a fixed limit frame, a movable limit frame and an adjusting support rod for controlling the flipping of the movable limit frame.

[0041] In order to monitor the angle of the transverse material guiding frame 9 , a distance measuring module 12 for monitoring the flipping angle of the transverse material guiding frame 9 is fixedly installed inside the transverse translation frame 8 .

[0042] The distance measuring module 12 is a laser distance meter, which measures the distance of the horizontal material guiding frame 9 to determine the flipping angle of the horizontal material guiding frame 9 .

[0043] In order to facilitate material discharge, a bottom collecting box 13 is installed on the side wall of the bottom base 2 at the discharge port of the bottom conveyor belt 6.

[0044] The screened fastening connectors are guided outwards through the bottom conveyor belt 6 and finally fall into the bottom collecting box 13 .

[0045] In order to cooperate with automatic control and reduce working energy consumption, a pressure touch switch 14 is installed on the lower surface of the main frame 1 at the connecting end of the first electric control support rod 41 and the second electric control support rod 42.

[0046] When a fastening connection is placed on the combined electric-controlled material feeding device 5 or the circulating external material returning device 7 , the pressure touch switch 14 is exposed to the downward pressure, and the pressure touch switch 14 starts the combined electric-controlled material feeding device 5 and the circulating external material returning device 7 .

[0047] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
