DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 6 As shown, a raw material lifting mechanism comprises a lifting unit 2, on which a conveying channel for conveying raw materials along a preset path is formed, and the horizontal height of the feeding end of the conveying channel is lower than the horizontal height of the discharging end of the conveying channel;

[0026] The machine also includes a material return unit 1, which includes a container part and a lifting part. The top of the container part is open to form a cavity for receiving raw materials, and the cavity is below the lowest end of the conveying channel. The lifting part includes two symmetrically arranged first base plates 15, and two first transmission rollers 16 are symmetrically rotatably connected between the two first base plates 15. A first conveyor belt 17 is sleeved between the two first transmission rollers 16. A plurality of first loading plates 18 are fixedly connected to the outer side of the first conveyor belt 17 in an annular array, and a lifting cavity for accommodating raw materials is formed between two adjacent first loading plates 18. The bottom of the first conveyor belt 17 is inside the cavity, and the first conveyor belt 17 is above the conveying channel. A first motor 19 is fixedly connected to the first base plate 15, and the output end of the first motor 19 is connected to one of the first transmission rollers 16.

[0027] Through the above technical scheme, when personnel need to lift raw materials, the raw materials are added to the conveying channel on the lifting unit 2, and the lifting unit 2 works, so that the lifting unit 2 conveys the raw materials along the conveying channel until the raw materials move to a high place, so that the raw materials are conveyed to the crusher for crushing, and when the lifting unit 2 lifts the raw materials, if part of the raw materials accidentally slip, the cavity on the container part receives the fallen raw materials, so that the accidentally fallen raw materials are collected in the cavity, and the first motor 19 works, so that the first motor 19 drives the first transmission roller 16 on the first substrate 15 to rotate, and the first transmission roller 16 drives the first conveyor belt 17 to rotate, and the first loading plate 18 on the first conveyor belt 17 cooperates, so as to drive the recovered raw materials in the cavity to move upward, until the raw materials fall into the conveying channel on the lifting unit 2, and the recycling of the raw materials is completed.

[0028] In addition, in the present invention, regarding the container part:

[0029] like Figure 1-Figure 2 , Figure 5 As shown, the container part includes a material receiving box 11, the top of which is recessed to form a material storage cavity 12 for accommodating raw materials, and the material storage cavity 12 is inclined downward from the inner wall toward one side of the first conveyor belt 17 to form a material guiding slope, and the first substrate 15 is fixedly connected to the material receiving box 11.

[0030] Through the above technical solution, when raw materials fall from the lifting unit 2, the raw materials are received by the storage cavity 12 on the receiving box 11, so that the raw materials are recovered, and when the raw materials are recovered, the raw materials are guided to gather toward the first conveyor belt 17 through the material guide slope.

[0031] In order to facilitate the gathering of raw materials to the lifting unit 2, Figure 5-Figure 6As shown, two movable push plates 13 are symmetrically arranged inside the storage chamber 12, and two first base plates 15 are located between the two push plates 13. The first electric push rods 14 are fixedly connected to the symmetrical sides of the material receiving box 11, and the telescopic end of the first electric push rod 14 is fixedly connected to the side of the push plate 13 away from the first base plate 15.

[0032] Through the above technical solution, when the raw materials are collected into the storage chamber 12, the first electric push rod 14 works to drive the push plate 13 to move, and the push plate 13 drives the raw materials in the storage chamber 12 to move toward the first loading plate 18, so that the recovered raw materials can be easily loaded into the first loading plate 18 on the first conveyor belt 17, thereby improving the utilization efficiency of the raw materials during recovery.

[0033] Specifically, in one embodiment, regarding the lifting unit 2:

[0034] like Figure 1-Figure 4 As shown, the lifting unit 2 includes a base 210, and two second base plates 24 are rotatably connected to the top of the base 210, and two second transmission rollers 22 are symmetrically rotatably connected between the two second base plates 24. A second conveyor belt 211 is sleeved between the two second transmission rollers 22, and the outer peripheral surface of the second conveyor belt 211 is fixedly connected to a plurality of second loading plates 29 in a circular array, and a second motor 23 is fixedly connected to one of the second base plates 24, and the output end of the second motor 23 is connected to one of the second transmission rollers 22.

[0035] Through the above technical solution, when the raw materials are added to the second conveyor belt 211, the second motor 23 is operated, and then the second motor 23 drives the second transmission roller 22 on the second substrate 24 to rotate, and the second transmission roller 22 drives the second conveyor belt 211 to rotate, and the second loading plate 29 on the second conveyor belt 211 moves, and then the second loading plate 29 drives the raw materials to move to a higher place, so that the raw materials are transported to the crusher for crushing.

[0036] In order to adjust the lifting height of the second conveyor belt 211, as Figure 1-Figure 4 As shown, the third motor 25 is fixedly connected to the opposite sides of the two second substrates 24 , the output end of the third motor 25 is connected to a connecting shaft 27 , and the connecting shaft 27 is fixedly connected to a second electric push rod 26 .

[0037] Through the above technical solution, when personnel need to adjust the lifting height of the second conveyor belt 211, the third motor 25 drives the connecting shaft 27 to rotate, thereby adjusting the angle of the second electric push rod 26. After the angle of the second electric push rod 26 is adjusted, the second electric push rod 26 works, thereby allowing the telescopic end of the second electric push rod 26 to extend and retract, so that the telescopic end of the second electric push rod 26 contacts the base 210, and the second base plate 24 rotates around the base 210, thereby adjusting the angle of the second base plate 24, and then adjusting the lifting height of the second conveyor belt 211.

[0038] When the first conveyor belt 17 lifts the recycled raw materials to a high position, in order to facilitate the recycled raw materials to be added back to the second conveyor belt 211, as shown in FIG. Figure 1-Figure 3 As shown, a shield 21 is fixedly connected between the tops of the two second base plates 24 , and the top of the shield 21 is opened to form a feed hole 28 , and the feed hole 28 is located below the highest position of the first conveyor belt 17 .

[0039] Through the above technical solution, when the first conveyor belt 17 and the first loading plate 18 drive the raw materials to a high place and discharge them, the raw materials are received by the feed hole 28 on the baffle 21, making it easy to add the raw materials to the second conveyor belt 211 and reducing the chance of accidental falling of the materials from the second conveyor belt 211.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
