The main structure of the waste collection device is a collection box 1. The collection box 1 is a box-shaped structure with an open top. The storage space inside is used to store waste. The shape of the horizontal cross-section of the storage space can be, but is not limited to, a rectangle, that is, the collection box 1 can be set to be in a cubic shape, with its length direction being the second direction y and its width direction being the first direction x perpendicular to the second direction y. Taking the waste collection device applied to collecting burrs removed from photovoltaic modules after lamination as an example, the collection box 1 needs to have a longer length in the second direction y to adapt to the edge length of the burr removal platform, so as to completely receive and collect the burr waste removed from one side of the burr removal platform as much as possible, thereby reducing the workload of manual cleaning. The specific length can be set according to actual conditions.

[0041] In order to facilitate the movement of the device, a plurality of pulleys 2 are provided at the bottom of the collection box 1, so that when there is too much waste in the collection box 1, the staff can conveniently move the device to the position for dumping the waste, and can also return the device to its place conveniently and labor-savingly after dumping, which is convenient to operate and saves labor; the number of pulleys 2 can be set to at least four, and at least one pulley 2 is provided at each of the four corners of the bottom plate 14 of the collection box 1 to ensure the stability of the collection box 1; the pulley 2 can adopt a universal pulley 2 with a locking valve, which is convenient for moving the device and can lock the current position when the device moves to a specified position.

[0042] Reference Attachment Figure 1 and attached Figure 2 In order to facilitate the collection of waste, the collection box 1 includes a first side wall 11 and a second side wall 12 opposite to each other in a first direction x. The first side wall 11 and the second side wall 12 can be rectangular flat plates. The first side wall 11 is located on the side close to the burr cutting platform, and an inclined guide plate 13 is provided on the top of the first side wall 11.

[0043] Among them, the heights of the first side wall 11 and the second side wall 12 can be equal, that is, the inclined guide plate 13 is higher than the main body height of the collection box body 1. Such a setting is conducive to increasing the volume of the collection box body 1 to collect more waste; or the height of the first side wall 11 can be lower than the second side wall 12, and the height of the first side wall 11 after adding the inclined guide plate 13 can be higher than the second side wall 12 or flush with the height of the second side wall 12, which is conducive to controlling the overall size of the device and reducing the space occupied by the device; the heights of the first side wall 11 and the second side wall 12, the height of the inclined guide plate 13 and the inclination angle can be adaptively designed according to the space on the side of the burr cutting platform, and the heights of the remaining side walls of the collection box body 1 can be set to be equal to the height of the second side wall 12.

[0044] Reference Attachment Figure 1 -Attached Figure 3 In order to facilitate the staff to pour out the waste in the collection box 1, in the technical solution adopted by the utility model, a discharge port 1201 is provided at the bottom of the second side wall 12, and the discharge buckle extends along the second direction y. The extended length can be the length of the second side wall 12 or close to the length of the second side wall 12, and a baffle plate 3 is movably connected to the second side wall 12. The movable connection here means that the baffle plate 3 can reciprocate longitudinally relative to the second side wall 12 after installation, and can be moved to a position where the discharge buckle is completely blocked, as shown in the attached figure. Figure 1As shown, the second side wall 12 is closed during the process of collecting waste materials to prevent waste materials from leaking out; or the baffle plate 3 can also move to a position where the discharge port 1201 is exposed, as shown in the appendix Figure 2 As shown, when there is too much waste material in the collection box 1, the staff moves the device to the position where the waste material is dumped. By adjusting the baffle plate 3 to expose the discharge port 1201, the waste material in the collection box 1 can be conveniently poured out of the box through the discharge port 1201, which saves time and effort.

[0045] Among them, the movable connection between the baffle plate 3 and the second side wall 12 can be, but is not limited to, one of connection methods such as sliding connection and plug connection, which will be described in detail below.

[0046] According to the above, an embodiment of the present invention provides a waste material collection device.

During the process of collecting waste materials, the baffle plate 3 moves to a position where the discharge opening is completely blocked to prevent waste materials from leaking out; when there is too much waste material in the collection box 1, the staff moves the device to the position where the waste material is dumped. By adjusting the baffle plate 3 to expose the discharge port 1201, the waste material in the collection box 1 can be conveniently poured out of the box through the discharge port 1201, and the operation is convenient and labor-saving.

[0047] Refer to the appendix Figure 1 and the appendix Figure 2, in order to realize the movable connection between the baffle plate 3 and the second side wall 12, in a specific implementation, the part of the second side wall 12 located at the top side of the discharge port 1201 is provided with a movable groove 1202 adapted to the baffle plate 3, and the adaptation here refers to the adaptation of the length and thickness in the second direction y, and the bottom of the movable groove 1202 is connected to the discharge port 1201, so that the guide plate can enter the movable groove 1202 from the discharge port 1201 or move out of the movable groove 1202 to discharge the material; in order to facilitate the staff to adjust the position of the guide plate, in the technical solution adopted by the present invention, at least two adjustment grooves 1203 are provided at intervals along the second direction y on the part of the second side wall 12 of the collection box body 1 located at the top of the discharge port 1201 and on the side away from the first side wall 11, each adjustment groove 1203 extends longitudinally And it is connected to the movable groove 1202, and correspondingly, at least two adjusting handles 4 are provided on the top of the baffle plate 3 and on the side away from the first side wall 11. One end of the adjusting handle 4 is movable through the corresponding adjusting groove 1203 and connected to the baffle plate 3, and the rest of the adjusting handle 4 is exposed on the outside of the second side wall 12. The adjusting handle 4 is the position that can be manually adjusted by the staff. The staff can adjust the position of the baffle plate 3 by manually controlling the adjusting handle 4, which is convenient for the staff to operate and can limit the movable trajectory and range of the baffle plate 3 through the cooperation of the adjusting handle 4 and the adjusting groove 1203; when the adjusting handle 4 is located at the bottom end of the adjusting groove 1203, the baffle plate 3 blocks the discharge port 1201; when the adjusting handle 4 is located at the top end of the adjusting groove 1203, the baffle plate 3 exposes the discharge port 1201.

[0048] Among them, the part of the adjustment handle 4 located inside the adjustment groove 1203 can be set to a size in the second direction y that is compatible with the adjustment groove 1203, and the part of the adjustment handle 4 exposed on the outside of the second side wall 12 can be set to any shape and larger than the size of the adjustment groove 1203 to improve the comfort of manual operation of the staff.

[0049] Reference Attachment Figure 1 and attached Figure 2 In order to improve the sealing effect of the material baffle plate 3 when blocking the material baffle opening, in a specific implementation, the collection box body 1 further includes a bottom plate 14 located between the bottom of the first side wall 11 and the second side wall 12, and a slot 1401 extending along the second direction y is provided on the bottom plate 14 corresponding to the position of the discharge port 1201, and the opening of the slot 1401 is located on the top side facing the discharge port 1201; the bottom end of the material baffle plate 3 is provided with a plug-in portion 31 adapted to the slot 1401, and when the material baffle plate 3 blocks the discharge port 1201, the plug-in portion 31 is plugged into the slot 1401; this can further improve the sealing effect of the material baffle plate 3 on the collection box body 1 when blocking the material baffle opening, can prevent waste or dust from being exposed from the gap, and the cooperation of the plug-in portion 31 and the slot 1401 can improve the stability of the position of the material baffle plate 3.

[0050] Specifically, in order to avoid jamming when the insertion part 31 is engaged with the slot 1401, in the technical solution adopted by the present utility model, with reference to the attached Figure 1 and the attached Figure 2 , the slot 1401 includes a first slot wall and a second slot wall opposite to each other in the first direction x. At least one of the first slot wall and the second slot wall can be set as an inclined slot wall, so that the width of the slot 1401 in the first direction x gradually increases from the slot bottom to the slot opening. The inclined slot wall can play a guiding role and enable the insertion part 31 to enter the slot 1401 more conveniently; wherein, the insertion part 31 can be provided with an inclined surface corresponding to the slot 1401, or can also be set as a vertical surface.

[0051] With reference to the attached Figure 1 -the attached Figure 3 , in order to make it more labor-saving to pour the waste out of the collection box 1, in a specific implementation, a first insertion hole 1204 is provided on the surface of the second side wall 12 facing away from the first side wall 11 and above the adjustment slot 1203. The cross-sectional shape of the first insertion hole 1204 can be circular, and a second insertion hole 401 matching the first insertion hole 1204 is correspondingly provided at the top of the adjustment handle 4. The shapes and sizes of the first insertion hole 1204 and the second insertion hole 401 are exactly the same; when the adjustment handle 4 is located at the top of the adjustment slot 1203, the first insertion hole 1204 and the second insertion hole 401 correspond. By sequentially inserting the limit plug 5 into the second insertion hole 401 and the second insertion hole 401, the positions of the adjustment handle 4 and the baffle 3 can be fixed and maintained, avoiding the baffle 3 from discharging materials, so that the staff does not need to always control the adjustment handle 4, which can be more labor-saving.

[0052] Specifically, the number of the above-mentioned adjustment slots 1203 and adjustment handles 4 is two respectively, and the two adjustment slots 1203 are symmetrically arranged in the middle area of the second side wall 12, which can improve the stability of the movement of the baffle 3 while being convenient for operation; in order to further improve the convenience of the staff's operation, in the technical solution adopted by the present utility model, with reference to the attached Figure 3 , a cross beam 6 is connected between the two adjustment handles 4 to connect the two adjustment handles 4 into one body, which is convenient for the staff to operate with one hand.

[0053] With reference to the attached Figure 1 and the attached Figure 2, the collection box 1 further includes a bottom plate 14 located between the bottoms of the first side wall 11 and the second side wall 12. In order to further facilitate the pouring out of the waste, in a specific implementation, the top surface of the bottom plate 14 can be set as an inclined top surface 14a, and the height of the inclined top surface 14a gradually decreases from the third edge connecting the first side wall 11 to the fourth edge connecting the second side wall 12. Here, the fourth edge also corresponds to the edge of the discharge port 1201.

The third side wall 15 and the fourth side wall are arranged opposite to each other in the second direction y and are respectively connected between the corresponding edges of the first side wall 11 and the second side wall 12. When moving the device, in order to facilitate the operation of the staff, in a specific implementation, a pull rod 7 is provided on the surface of the third side wall 15 facing away from the fourth side wall. The staff can control the movement of the collection box 1 through the pull rod 7. The pull rod 7 can be set as a straight rod arranged horizontally or obliquely, and the pull rod 7 and the collection box 1 can be detachably connected.

[0055] In a specific implementation, the inclined guide plate 13 can be set as a plate member with an adjustable angle. The inclined guide plate 13 can be rotatably connected to the first side wall 11 through a rotating shaft (not shown in the figure), and the rotating shaft extends along the first direction x, enabling the flipping of the inclined guide plate 13. Specifically, mounting seats can be respectively provided at the two ends of the top of the first side wall 11 and opposite to each other in the second direction y. The two ends of the rotating shaft respectively pass through the two mounting seats and can rotate relative to the mounting seats.
