Detailed Description
The cleaning device is described in detail below with reference to the accompanying drawings and examples.
Example 1
As shown in figures 1-3, the shellfish adhesion base cleaning device comprises a frame 1, wherein a driving roller 2 and a driven roller 3 are arranged at two ends of the frame, an annular conveying belt 4 is sleeved on the driving roller 2 and the driven roller 3, and the shellfish adhesion base cleaning device also comprises a motor 5 fixed with the bottom of the frame, and the motor 5 and the driving roller 2 are driven by a chain so as to drive the conveying belt 4 to walk.
As shown in fig. 1, 3 and 4, the press roller comprises a plurality of pairs of press rollers, each pair of press rollers comprises an upper roller 6 and a lower roller 7. As shown in fig. 1 and 3, the upper conveyor belt passes between the upper and lower rollers.
As shown in fig. 1 and 3, two ends of the lower roller 7 are supported on a lower frame 102 of the frame through supporting shafts, vertical slide ways 8 with the same number as the lower roller 7 are respectively arranged on the left side and the right side of the lower frame 102 of the frame, sliding blocks 9 are arranged in the vertical slide ways 8, two ends of the upper roller 6 are respectively fixed on the sliding blocks 9 through supporting shafts, the sliding blocks 9 are connected with an adjusting screw rod 10, and the adjusting screw rod 10 penetrates through the upper frame of the frame and is provided with a handle 11 at the top end.
In this embodiment, as shown in fig. 1, 3 and 4, there are 4 pairs of squeeze rollers, and a shower pipe 12 is provided between each pair of squeeze rollers, the shower pipe 12 crossing the conveyor belt 4.
As shown in fig. 1 and 3, each lower roller 7 is connected with the driving roller 2 through a chain, so that the lower rollers 7 and the conveyor belt 4 rotate synchronously.
As is apparent from the above description, when the shellfish attaching base is put on the conveyor belt to move forward along with the conveyor belt, the gap between the upper drum 6 and the conveyor belt 4 is adjusted by the screw 10 so that the shellfish attaching base is extruded by the upper drum 6 and the lower drum 7, the attached matter on the attaching base is crushed and separated from the attaching base by the extrusion, the shower 12 can spray seawater or detergent to the attaching base, foreign matter on the attaching base is finally removed by the action of the 4 pairs of extrusion drums, and the attaching base is cleaned.
In order to increase the extrusion and kneading effect on the adhesion base, the surface of the upper roller 6 is provided with protrusions distributed in a matrix, and the heights of the protrusions are 2-5mm.
In the embodiment, the conveyer belt is preferably a steel mesh belt, and the diameter of meshes on the mesh belt is 2-30 mm, so that crushed foreign matters and cleaning water can be timely leaked from the meshes.
Example 2
This example further optimizes example 1.
As shown in fig. 1, a spray pipe swinging device is added in the embodiment, and the spray pipe swinging device comprises longitudinal swinging rods 13 respectively arranged at two ends of each spray pipe, the top ends of the swinging rods 13 are connected with an upper frame body 102 of the frame through rotating shafts 14, and the swinging rods 13 can drive the spray pipes 12 to swing freely.
The structure of the device for driving the swing rod 13 to swing is shown in the accompanying drawings 1 and 2, a driven disc 15 is arranged on a rotating shaft at the top of the swing rod at one side, the driven disc 15 is circular, and a notch 151 is arranged at the edge of the disc body; a driving disc 16 is arranged on one side of the driven disc 15, and toggle teeth 161 matched with the notches are arranged on the edge of the driving disc 16.
As shown in fig. 2, the toggle teeth 161 can enter the notch 151 once for every rotation of the driving disk 16 and drive the driven disk 15 to rotate.
As shown in fig. 1, the belt conveyor further comprises a driving wheel 17 fixed on the upper frame body 101 of the frame, a supporting shaft of a non-driving end of the lower cylinder penetrates through the lower frame body on the side, a driving wheel 18 is arranged at the end part of the supporting shaft, and the driving wheel 18 is connected with the driving wheel 17 and the driving wheel 17 is connected with each driving disc 16 through a driving chain.
As can be seen from the above description, when the conveyor belt 4 moves, the driving wheel 18 rotates synchronously with the lower roller 7, the driving wheel 18 drives the driving wheel 17 and each driving disc 16 to rotate synchronously, the driving discs 16 rotate while driving the driven discs 15 in a time-sharing manner, the swing rod 13 is driven to swing by the rotation of the driven discs 15, and when the driven discs 15 do not rotate, the swing rod 13 naturally swings under the action of the gravity of the spray pipe 12.
According to the above arrangement, as shown in fig. 1 and 3, when the device is operated, the shower pipes 12 are simultaneously swung, so that the shower stroke of each shower pipe 12 can be increased, the adhesion base can be better cleaned, the problem that the shower pipes are fixed and concentrated in position and spray to the fixed position in embodiment 1 is solved, and the washing water and the detergent can be reduced by swinging the shower pipes, so that the adhesion base can be better cleaned.
Example 3
This embodiment further improves the device. When the adhesion base is extruded by the extrusion roller, the adhesion base is likely to be adhered to the surface of the upper roller and rise along with the rotation of the upper roller after passing through the pair of extrusion rollers, so that the adhesion base fails to move forward, meanwhile, sundries on the adhesion base are crushed, sundry dust is mixed between the adhesion base and the conveyor belt, and at the moment, the sundries are difficult to wash out even if the water passing through the spray pipe is cleaned.
As shown in fig. 1 and 3-5, comb plates 19 are provided at intervals on the surface of the conveyor belt 4. As shown in fig. 5, the comb plate 19 has a long strip shape, and the comb teeth 191 are provided at the edge of the comb plate.
As shown in fig. 4, the comb plate 19 spans the conveyor belt 4, two ends of the comb plate 19 are elastically hinged to the side edges of the conveyor belt 4, and the comb plate 19 is inclined and tilted on the surface of the conveyor belt as shown in fig. 1 and 3.
The elastic hinge between the comb plate 19 and the side edge of the conveyor belt 4 means that when the comb plate 19 is pressed, the comb plate 19 is rotated to be attached to the conveyor belt 4, and when the pressure is removed, the comb plate 19 is automatically sprung to be tilted. Since the elastic hinge is easily implemented by a person skilled in the art, it is not specifically described here.
As shown in fig. 1 and fig. 3, the comb plate 19 is inclined and tilted on the surface of the conveyor belt 4, which means that the comb plate forms an angle of 150 ° -165 ° with the travelling direction of the conveyor belt.
Through setting up above-mentioned comb plate after, after the adhesion matrix was placed in conveyer belt 4 top, the adhesion matrix was propped up by comb plate 19, keep certain distance between adhesion matrix and the conveyer belt 4, when passing through the extrusion cylinder, comb plate 19 is fallen down and is received the extrusion together with the adhesion matrix, after passing through the extrusion cylinder, comb plate 19 pops up, because the separation of comb plate 19, adhesion matrix is difficult to take place the adhesion with last cylinder 6, can guarantee the continuation of adhesion matrix, moreover the adhesion matrix debris after the crushing of extrusion cylinder is very easy by dropping on the adhesion matrix when the adhesion matrix was propped up by the comb plate, no impurity between adhesion matrix and the conveyer belt 4 can be hidden, after the spray of shower, the impurity is very easy by the adhesion matrix on drop and by the mesh on the conveyer belt, thereby greatly improved the cleaning performance of adhesion matrix.
