[0040] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention.

[0041] like Figures 1 to 3 As shown, a kitchen waste and large debris sorting device provided by the present invention includes a frame 4, a reduction motor 2 and a sorting transmission device. The reduction motor 2 is fixed to the frame 4 by a spring connecting piece 1. The sorting transmission device includes multiple transmission shafts 7 and a transmission assembly. The multiple transmission shafts 7 are connected by the transmission assembly. Each transmission shaft 7 is connected to multiple triangular disks 3 in the axial direction. A fine material outlet is formed between two adjacent transmission shafts 7, and a large debris outlet is formed at the transmission end of the sorting transmission device; a fixed sleeve 8 is provided at the rotation connection between any transmission shaft 7 and the frame 4 and the interval between two adjacent triangular disks 3; the reduction motor 2 is connected to the transmission assembly.

[0042] The reduction motor 2 of this utility model is flexibly connected to the frame 4 via a spring connector 1, which helps prevent direct impact from metal or other hard objects during the sorting process. A fixed sleeve 8 is installed at the rotational connection between each drive shaft 7 and the frame 4 and between two adjacent triangular discs 3. At the fine material outlet and the large debris outlet, the remaining rotating parts, except for the triangular discs 3, are shielded by the fixed sleeve 8, preventing the rotating parts from being exposed and causing long objects to become entangled and block the outlet.

[0043] Specifically, the formation of the fine material outlet includes multiple situations: one situation is that the triangular disks 3 on two adjacent transmission shafts 7 are arranged in a one-to-one correspondence, there is no gap between the one-to-one corresponding triangular disks 3 on the two adjacent transmission shafts 7, and the two one-to-one corresponding triangular disks 3 do not affect each other's rotation with the transmission shaft 7, and the fine material outlet is the gap between the two adjacent triangular disks 3 on each transmission shaft 7. Another situation is that the triangular disks 3 on two adjacent transmission shafts 7 are arranged in a one-to-one correspondence, there is a gap between the one-to-one corresponding triangular disks 3 on the two adjacent transmission shafts 7, and the two one-to-one corresponding triangular disks 3 do not affect each other's rotation with the transmission shaft 7, and the fine material outlet is composed of the gap between the two adjacent triangular disks 3 on each transmission shaft 7 and the gap between the one-to-one corresponding triangular disks 3. Another situation is that the triangular disks 3 on two adjacent transmission shafts 7 are staggered, and the two staggered triangular disks 3 do not affect each other's rotation with the transmission shaft 7, and the fine material outlet is composed of the gap between the two adjacent triangular disks 3 on each transmission shaft 7 and the gap between the one-to-one corresponding triangular disks 3. By setting different distances between two adjacent transmission shafts 7 and different positions of the triangular disks 3 on the two adjacent transmission shafts 7, the gap between the two adjacent transmission shafts 7 can be changed, which is beneficial for screening out fine particles of different particle sizes.

[0044] Specifically, multiple drive shafts 7 are mounted at equal intervals on the frame 4, and each drive shaft 7 is axially connected to triangular discs 3 that are spaced evenly apart. The fine material outlets formed by the multiple equally spaced drive shafts 7 and the triangular discs 3 on each equally spaced drive shaft 7 are uniform in size, allowing the screening of fine waste materials of similar particle sizes.

[0045] Specifically, the transmission assembly includes a sprocket transmission assembly, which includes a sprocket, a chain, and a sprocket box 6; the two ends of the transmission shaft 7 are respectively mounted on opposite sides of the frame 4, one end of the transmission shaft 7 extends outward from the frame 4 and is connected to the sprocket, and multiple transmission shafts 7 are connected by chain transmission, the sprockets are meshed with the chain, and the sprockets connected to each transmission shaft 7 are respectively accommodated in the sprocket box 6. The two ends of the transmission shaft 7 are respectively mounted on opposite sides of the frame 4 through a bearing seat 5, one end of the transmission shaft 7 extends outward from the frame 4 and is respectively connected to the sprocket, and the sprockets at the ends of two adjacent transmission shafts 7 are respectively connected by chain transmission, and a sprocket box 6 is further provided outside the chain and sprocket. A transmission shaft 7 located in the middle of the frame 4 is a drive shaft, which is correspondingly connected to the reduction motor 2. The reduction motor 2 drives the drive shaft to rotate, and the rotation of the drive shaft drives the other transmission shafts 7 to rotate together, thereby transporting large garbage to the transmission end of the sorting transmission device and screening out fine garbage.

[0046] like Figure 4As shown, a feed port 9 is provided at the upper end of the frame 4, and the feed port 9 is provided just above the starting end of the sorting transmission device. A guide plate 10 is provided between the feed port 9 and the sorting transmission device, and the guide plate 10 extends obliquely downward from the feed port 9 to the starting end of the sorting transmission device. A fine material discharge port is provided below the sorting transmission device, and the fine material discharge port is connected to the fine material collection box. A large debris discharge port is provided just below the conveying end of the sorting transmission device, and the large debris discharge port is connected to the large debris collection box. A material guide trough 11 is provided between the conveying end of the sorting transmission device and the large debris discharge port, and the cross-section of the material guide trough 11 is inverted V-shaped.

[0047] The reduction motor 2 of the utility model is fixed to the frame 4 through the spring connecting piece 1. The reduction motor 2 is connected to a transmission shaft 7 located in the middle of the frame 4 through the output shaft. This transmission shaft 7 is the driving shaft. The reduction motor 2 drives the driving shaft to rotate. The two ends of the transmission shaft 7 are respectively installed on the frame 4 through the bearing seat 5. All the transmission shafts 7 are connected together by the sprocket box 6 to rotate synchronously. The sorting process of this sorting equipment includes:

[0048] (1) Place the kitchen waste into the entrance of the sorting equipment, where the waste enters the starting end of the sorting transmission device along the guide plate 10;

[0049] (2) The garbage is transported forward by the rotation of the transmission shaft 7;

[0050] (3) During the conveying process, objects smaller than a certain particle size fall through the gap between the two shafts and are sorted out;

[0051] (4) Large debris cannot be sorted due to its size and continues to be transported forward until it reaches the conveying end of the sorting transmission device and falls into the large debris outlet.
