[0026] 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.

[0027] like Figure 1-4 As shown, a domestic waste screening device comprises a screening box 1, a material receiving frame 11 is arranged inside the screening box 1, a screening mechanism 2 is arranged on the upper part of the material receiving frame 11, the screening mechanism 2 is transmission-connected to a driving mechanism 3, and a feed port 12 is opened on the upper part of the screening box 1;

[0028] The screening mechanism 2 includes two screening rollers 201 rotating relatively to each other, and the two screening rollers 201 both have a plurality of screening rods 202 in a circular array. The screening rods 202 on one screening roller 201 are arranged alternately with the screening rods 202 on the other screening roller 201. Partition plates 203 are provided on both sides below the screening roller 201. There are three material receiving frames 11, and the three material receiving frames 11 are located between the two partition plates 203. An isolation plate 204 inclined toward the upper middle part is provided above the partition plate 203, and a make way groove for the screening rods 202 is provided on the isolation plate 204.

[0029] By adopting the technical solution of this embodiment, domestic garbage enters the screening box 1 from the feed inlet 12, and reaches the receiving frame 11 after being screened by the screening mechanism 2. The transmission shaft of the screening roller 201 is connected to the driving mechanism 3, and the screening rod 202 drives the domestic garbage to move. The partition 203 is located on both sides below the screening rod 202, and a gap is left between the partition 203 and the top of the screening box 1. Large pieces of domestic garbage are driven by the screening rod 202 to the receiving frames 11 on both sides. The isolation plate 204 is arranged at an angle, and large pieces of garbage that cannot pass through the screening rod 202 fall into the receiving frames 11 on both sides through the isolation plate 204. Since the screening rod 202 on one screening roller 201 is staggered with the screening rod 202 on the other screening roller 201, the screening rod 202 will not collide when the screening roller 201 rotates.

[0030] Reference Figure 3 : The driving mechanism 3 is used to make the two screening rollers 201 rotate outward relative to each other.

[0031] In this embodiment, when the screening roller 201 rotates outward, the domestic waste entering from the feed port 12 falls onto the screening rod 202, small pieces of domestic waste reach the middle receiving frame 11 through the gaps between the screening rods 202, and large pieces of domestic waste are rotated by the screening rods 202 to the receiving frames 11 on both sides.

[0032] Reference Figure 1-2 The driving mechanism 3 includes two gears 301, two conveyor belts 302, two active pulleys 303, two driven pulleys 304 and a motor 305. The transmission shafts of the two gears 301 are rotatably connected to the screening box 1. The two gears 301 are meshed and transmission-connected. The output shaft of the motor 305 is transmission-connected to the transmission shaft of a gear 301. The two active pulleys 303 are transmission-connected to the transmission shaft of the gear 301. The two driven pulleys 304 are transmission-connected to the output shaft of the screening roller 201. The two conveyor belts 302 are transmission-connected between a active pulley 303 and a driven pulley 304.

[0033] In this embodiment, the gear 301 is used to realize the opposite rotation directions of the two screening rollers 201, thereby realizing the relative rotation of the two screening rollers 201. The conveyor belt 303 is used to realize long-distance transmission without changing the transmission direction. When the screening roller 201 is driven to rotate directly by the gear 301, the size of the gear 301 will be limited, and it is inconvenient to select the model of the gear 301. During operation, the motor 305 drives the transmission shaft of the gear 301 to rotate, and one gear 301 drives the other gear 301 to rotate. The two gears 301 rotate relative to each other. The two conveyor belts 303 respectively transmit the power of the transmission shaft of the gear 301 to the two screening rollers 201, thereby realizing the relative outward rotation of the two screening rollers 201.

[0034] Reference Figure 2 : The two gears 301 are located on the same vertical line.

[0035] Reference Figure 1-4 : The upper shell of the screening box 1 is semicircular, and the end of the screening rod 202 is slidably connected to the inner side of the upper part of the screening box 1.

[0036] In this embodiment, when the screening roller 201 rotates, it drives the screening rod 202 to rotate, and large pieces of domestic waste fall into the gap of the screening rod 202. The screening rod 202 is slidingly connected to the upper part of the screening box 1 to prevent the domestic waste from falling directly into the receiving frame 11 without being screened.

[0037] Reference Figure 1 The screening box 1 is assembled and connected with a protective shell 4, and the gear 301, the conveyor belt 302, the driving pulley 303 and the driven pulley 304 are assembled and connected in the protective shell 4.

[0038] In this embodiment, the protective shell 4 is used to prevent the gear 301, the conveyor belt 302, the driving pulley 303 and the driven pulley 304 from being directly exposed to the outside, thereby extending the service life of the components.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
