Description

Technical Field

[0001] The utility model relates to the technical field of restaurant and kitchen garbage treatment, in particular to a live net device for a sorting machine. Background Art

[0002] The current crusher blade group used to crush food waste (such as restaurant waste) mainly includes a main shaft, a plurality of blade holders arranged at intervals on the main shaft, and a blade shaft evenly arranged on the outer edge of the blade holder, and a blade plate and a hammer are located on the blade shaft. The blade holder structure used in this blade group is an integrated design, so there are certain disadvantages. Since restaurant waste is a high-humidity, sticky material, when the blade plate and hammer on the blade shaft are replaced over time, the entire blade shaft needs to be removed. Since the blade shaft passes through the blade holder for fixation, it is difficult to remove the blade shaft from multiple blade holders after it is rusted, resulting in the need to replace the entire blade group.

[0003] For this purpose, our company has developed a restaurant kitchen waste crushing and sorting device (CN214864036U), which includes a shell and a screen drum located in the shell, a feeding hopper is arranged on the upper side of one end of the screen drum, and a discharge port is arranged on the lower side of the other end of the screen drum. The two ends of the spiral fixed drum are supported in the screen drum by supporting shafts respectively. The spiral fixed drum from the feeding end to the discharging end is respectively composed of a beating zone, a spiral pushing zone, and a beating and discharging zone. The outer side walls of the spiral fixed drum in the beating zone and the beating and discharging zone are evenly provided with multiple beating plates inclined to the surface of the spiral fixed drum, and the beating plates are multiple circles. The surface of the spiral fixed drum in the spiral pushing zone is fixed with multiple spiral fan blades arranged at intervals, and the supporting shaft at one end is provided with a driven pulley, which is connected to the driving pulley of the driving motor through a transmission belt. The device can better adapt to the crushing and sorting of restaurant kitchen waste, with higher efficiency and less prone to clogging. However, during use, it was found that the screen drum would become clogged and worn over time and needed to be cleaned and replaced. The existing screen drum structure was fixed by welding and was difficult to remove, and the knife shaft needed to be disassembled. This was not only inconvenient for cleaning and maintenance, but once the screen drum was worn, the entire equipment needed to be replaced, causing great losses to customers. Utility Model Content

[0023] As Figure 1-7 shown, a sorting machine movable net device includes arc - shaped frame mechanisms 1 symmetrically arranged up and down and arc - shaped screens 2 respectively located on the inner arc surfaces of the arc - shaped frame mechanisms 1. For the convenience of feeding and discharging, one end of the upper arc - shaped screen 2 is provided with a feed inlet 5, and the other end of the lower arc - shaped screen 2 is provided with a discharge outlet 6. One side of the upper and lower arc - shaped frame mechanisms 1 is rotatably connected, and after the upper and lower arc - shaped frame mechanisms 1 and the upper and lower arc - shaped screens 2 are buckled, a cylindrical structure is formed.

[0024] Specifically: The arc - shaped frame mechanism 1 includes a plurality of arc - shaped plates 101 and connecting plates 102 for fixedly connecting adjacent arc - shaped plates 101. The rotating ends of each arc - shaped plate 101 are respectively fixed with outward - extending rotating swing arms 103. The outer ends of the upper and lower rotating swing arms 103 are respectively provided with hollowed - out openings. Each rotating swing arm 103 is respectively rotatably connected to the openings arranged up and down on one side of the fixed connecting plate 104 through the openings and pin shafts, so that each arc - shaped frame mechanism 1 can respectively rotate around.

[0025] In order to facilitate the rotation and fixation of the rotating swing arms 103, the cross - section of the fixed connecting plate 104 is in the shape of the letter 'E'. A positioning I - beam 105 arranged along the axial direction of the arc - shaped frame mechanism 1 penetrates between the upper and lower rotating swing arms 103, and the upper and lower clamping grooves of the fixed connecting plate 104 are respectively clamped on the upper and lower edges of the positioning I - beam 105 on the same side.

[0026] On the opening and closing sides of each arc-shaped frame mechanism 1, there are respectively fixed sieve plate fixing plates 106 with mounting holes. The holes on the sieve plate fixing plate 106 are used to squeeze and correct the arc-shaped sieve mesh into a circular shape when fixing. Especially when the arc-shaped sieve mesh is plate-shaped or close to a semi-circular arc, it can also make the outer side wall of the arc-shaped sieve mesh closely adhere to the inner side of the arc-shaped frame mechanism 1. On the inner edge of the rotating end of each arc-shaped plate 101, there are respectively provided slots 107. On the opening and closing sides of each arc-shaped sieve mesh 2, there are respectively provided fixing edges 3 parallel to the sieve plate fixing plate 106. The fixing edges 3 are provided with a plurality of mounting holes. The mounting holes on the fixing edges 3 and the mounting holes on the sieve plate fixing plate 106 are fixedly connected by bolts and nuts to achieve the purpose of squeezing and correcting, ensuring that the upper and lower arc-shaped sieve meshes 2 can form a complete circle. On the rotating side edges of each arc-shaped sieve mesh 2, there are respectively provided retaining edges 4 inserted into the slots 107.

[0027] At the opening and closing ends of each arc-shaped plate 101 of the upper and lower arc-shaped frame mechanisms 1, there are respectively fixed outwardly extending fixing arms 108. The outer ends of adjacent fixing arms 108 are fixedly connected by a positioning plate 109. Between the upper and lower positioning plates 109, there is provided a fixing I-beam 110 arranged along the axial direction of the arc-shaped frame mechanism 1. The upper and lower edges of the outer side of the fixing I-beam 110 are respectively provided with fixing holes. The positioning plates 109 are also provided with fixing holes. The upper and lower positioning plates 109 are respectively fixedly connected to the upper and lower edges of the fixing I-beam 110 by bolts and nuts.

[0028] To facilitate the fixed installation of the arc-shaped frame mechanism 1 in the sorting machine, at both ends of the positioning I-beam 105 and the fixing I-beam 110, there are respectively provided mounting plates 7 with I-shaped openings. The two ends of the positioning I-beam 105 and the fixing I-beam 110 are respectively inserted into the I-shaped openings of the mounting plates 7. At the four corner parts of each mounting plate 7, there are respectively provided mounting holes;

[0029] To improve the overall strength, the middle parts of adjacent arc-shaped plates 101 are fixedly connected by a reinforcing plate 112, whose function is to strengthen the connection strength between the middle parts of adjacent arc-shaped plates 101. The arc-shaped plates 101 on one side of each sieve plate fixing plate 106 are also strengthened and connected by a reinforcing rib 111 to prevent the problem of deformation of the connection of the sieve plate fixing plate 106.

[0030] The working principle of the present utility model: Each mounting plate 7 is correspondingly fixed at the shell of a kitchen waste crushing and sorting device (CN214864036U), so that the entire arc-shaped frame mechanism 1 and the upper and lower arc-shaped sieve meshes 2 are installed in the shell to replace the sieve cylinder without affecting the normal operation of the kitchen waste crushing and sorting device (CN214864036U);

[0031] When replacing the upper arc-shaped screen 2, remove the bolts and nuts of the upper arc-shaped screen 2, the screen plate fixing plate 106, the positioning plate 109 and the fixed I-beam 110. At this time, the upper arc-shaped screen 2 can be rotated upward to open, so as to facilitate the removal of the upper arc-shaped screen 2 for replacement. The working principle of replacing the lower arc-shaped screen 2 is the same. When replacing the upper and lower arc-shaped screens 2, only need to remove the corresponding bolts and nuts and rotate to open the corresponding arc-shaped frame mechanism 1, then the arc-shaped screen 2 can be pulled out from the arc-shaped frame mechanism 1, which is not only convenient for installation and assembly, but also convenient for later maintenance and replacement.

[0032] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
