Description
Technical Field
[0001] This utility model relates to the technical field of artificial turf cleaning equipment, and more specifically, to an artificial turf cleaning device. Background Technology
[0002] Artificial turf cleaning devices are used to clean debris from artificial turf, such as dust, soil, seeds, bird droppings, leaves, and sand. Currently, US Patent Publication No. US11134622B2 discloses an artificial turf cleaning device. The collection box in this device is parallelepiped in shape, having two side walls, a base, a rear wall, and a top plate extending above the side walls. A hinged cover is rotatably connected to the front of the top plate, and the hinged cover and the top plate cover the entire upper part of the collection box. However, this type of collection box has disadvantages such as complex structure, high manufacturing cost, and inconvenient connection to the main unit. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an artificial turf cleaning device, whose internal material bag for collecting debris has the advantages of simple structure and convenient connection with the main unit.
[0004] This utility model provides an artificial turf cleaning device, including a main unit; the artificial turf cleaning device also includes a connecting frame and a material bag made of flexible material, the front end of the material bag forms an inlet, and the inlet is circumferentially fixed to the connecting frame; a number of support blocks are provided on the rear side of the main unit at intervals from left to right, and each support block has a slot with an open top on its inner side, and the upper side of the connecting frame is inserted into the number of slots so that the material bag is detachably connected to the main unit.
[0005] By adopting the above structure, this utility model directly forms a collection component for collecting debris from a bladder made of flexible material. It has the advantages of simple structure and low cost. Furthermore, since the bladder's inlet is connected to the main unit through a snap-fit connection between the connecting frame and the main unit, it has the advantage of easy assembly and disassembly of the bladder and the main unit.
[0006] In one possible implementation, the artificial turf cleaning device further includes a support frame, the front end of which is fixed to the upper side of the connecting frame. The support frame gradually tilts upward from front to back. The support frame is inserted into the feed bladder through the feed inlet and supports the inner top of the feed bladder. By setting up the support frame, since the support frame is inserted into the feed bladder through the feed inlet and supports the inner top of the feed bladder, the collapse of the feed bladder can be avoided. It also allows the debris cleaned by the main unit from the artificial turf to smoothly enter the interior of the feed bladder through the feed inlet, and facilitates the storage of debris in the feed bladder.
[0007] In one possible implementation, a limiting block is provided on the inner wall of each slot. When the upper side of the connecting frame is inserted into the slot, the upper side of the connecting frame abuts against the lower end of the limiting block to prevent the connecting frame from freely detaching from the host. With this structure, under the action of the limiting block, when the upper side of the connecting frame is inserted into the slot, the upper side of the connecting frame can abut against the lower end of the limiting block, thereby effectively preventing the upper side of the connecting frame from freely detaching from the slot from bottom to top, thus improving the reliability and stability of the upper side of the connecting frame after it is inserted into the slot.
[0008] In one possible implementation, each limiting block has a guide surface at its upper end. The guide surface is used to cooperate with the upper side of the connecting frame to guide it so that the upper side of the connecting frame can be inserted into the slot. With this structure, when the upper side of the connecting frame is engaged with the slot, the guide surface can cooperate with the upper side of the connecting frame to guide it so that the upper side of the connecting frame can be inserted into the slot, which can facilitate the assembly of the connecting frame and the host.
[0009] In one possible implementation, the main unit is internally equipped with an electronic control unit (ECU), which is connected in series in the main unit's control circuit. A triggering component is provided on the connecting frame. After the upper side of the connecting frame is engaged with several slots to assemble the bladder with the main unit, the triggering component triggers the ECU to electrically connect it. With this structure, since the ECU is connected in series in the main unit's control circuit, and the triggering component can only activate the ECU to electrically connect it after the upper side of the connecting frame is engaged with several slots, the main unit cannot be started when the bladder is not installed, thus avoiding accidental start-up of the main unit and improving safety.
[0010] In one possible implementation, the triggering component includes a trigger plate fixed to the connecting frame; the electronic control unit includes a micro switch, a movable block, and a spring; the micro switch is fixed inside the main unit, the movable block is movably connected to the inside of the main unit, the two ends of the spring abut against the inner wall of the main unit and the front end of the movable block respectively, and an opening slot is provided on the rear side wall of the main unit; when the upper side of the connecting frame is engaged in several slots, the trigger plate abuts against the rear end of the movable block and pushes the movable block from back to front to trigger the trigger end of the micro switch; when the connecting frame is separated from the main unit, the spring pushes the movable block to move backward to reset so that the movable block releases the trigger state of the micro switch; by adopting this triggering component and electronic control unit, after the bladder is assembled with the main unit, i.e., in the connecting frame After the upper side of the frame is inserted into several slots, the trigger plate can abut against the rear end of the movable block and push the movable block from back to front to trigger the trigger end of the micro switch. At this time, the micro switch is turned on, allowing the main unit to be started. When the bladder is separated from the main unit, that is, after the connecting frame is separated from the main unit, the spring can push the movable block to move backward and reset so that the movable block releases the trigger state of the micro switch. At this time, the micro switch is in the open circuit state, that is, the main unit cannot be started. In other words, the main unit cannot be started when the bladder is not installed, thus avoiding accidental start of the main unit and improving safety. In addition, the two ends of the spring are respectively engaged with the inner wall of the main unit and the front end of the movable block, thereby limiting the spring and preventing the spring from detaching from the main unit and the movable block.
[0011] In one possible implementation, a ramp is provided at the front end of the movable block and on the side facing the micro switch. When the movable block moves from back to front, the ramp is used to guide the trigger end of the micro switch so that the trigger end of the micro switch abuts against the outer wall of the movable block on the side facing the micro switch. With this structure, under the action of the ramp, when the movable block moves from back to front, the ramp can guide the trigger end of the micro switch so that the trigger end of the micro switch abuts against the outer wall of the movable block on the side facing the micro switch, thereby facilitating the movable block to trigger the trigger end of the micro switch to turn on the micro switch.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0024] See Figure 1-8As shown in the figure, this application discloses an artificial turf cleaning device, including a main unit 1; the artificial turf cleaning device also includes a connecting frame 2 and a material bag 3 made of flexible material, the front end of the material bag 3 forms a feeding port, and the feeding port is circumferentially fixed to the connecting frame 2; a plurality of support blocks 11 are provided on the rear side of the main unit 1, which are spaced apart from left to right, and each support block 11 has a slot 12 with an open top on its inner side, and the upper side of the connecting frame 2 is inserted into the plurality of slots 12 so that the material bag 3 is detachably connected to the main unit 1.
[0025] The artificial turf cleaning device also includes a support frame 4. The front end of the support frame 4 is fixed to the upper side of the connecting frame 2. The support frame 4 gradually tilts upward from front to back. The support frame 4 is inserted into the material bag 3 through the inlet of the material bag 3 and supports the inner top of the material bag 3. By setting the support frame, since the support frame is inserted into the material bag through the inlet of the material bag and supports the inner top of the material bag, the collapse of the material bag can be avoided. It also allows the debris cleaned by the main unit from the artificial turf to smoothly enter the interior of the material bag through the inlet, and facilitates the storage of debris in the material bag. In addition, several fasteners are circumferentially fixed at the front opening of the material bag, and the opening end of the material bag is fastened to the connecting frame by several fasteners. The bottom edge of the material bag is made of a rigid material, such as a rigid plastic material, so as to ensure that the shape of the bottom of the material bag does not deform.
[0026] Each slot 12 has a limiting block 13 on its inner wall. When the upper side of the connecting frame 2 is inserted into the slot 12, the upper side of the connecting frame 2 abuts against the lower end of the limiting block 13 to prevent the connecting frame 2 from freely detaching from the host 1. With this structure, under the action of the limiting block, when the upper side of the connecting frame is inserted into the slot, the upper side of the connecting frame can abut against the lower end of the limiting block, thereby effectively preventing the upper side of the connecting frame from freely detaching from the slot from bottom to top, which improves the reliability and stability of the upper side of the connecting frame after it is inserted into the slot.
[0027] Each limiting block 13 has a guide surface 131 at its upper end. The guide surface 131 is used to cooperate with the upper side of the connecting frame 2 to guide the upper side of the connecting frame 2 into the slot 12. With this structure, when the upper side of the connecting frame is engaged with the slot, the guide surface can cooperate with the upper side of the connecting frame to guide the upper side of the connecting frame into the slot, which facilitates the assembly of the connecting frame and the host.
[0028] The main unit 1 is equipped with an internal electronic control unit, which is connected in series in the control circuit of the main unit 1. A triggering component is provided on the connecting frame 2. When the upper side of the connecting frame 2 is engaged in several slots 12 to complete the assembly of the material bag 3 with the main unit 1, the triggering component is used to trigger the electronic control unit to make the electronic control unit electrically conductive. With this structure, since the electronic control unit is connected in series in the control circuit of the main unit, and the triggering component can only trigger the electronic control unit to make the electronic control unit electrically conductive after the upper side of the connecting frame is engaged in several slots, that is to say, the main unit cannot be started when the material bag is not installed, thereby avoiding accidental start of the main unit and improving safety.
[0029] The triggering component includes a trigger piece 21 fixed on the connecting frame 2; the electronic control unit includes a micro switch 5, a movable block 6, and a spring 7; the micro switch 5 is fixed inside the main unit 1, the movable block 6 is movably connected to the inside of the main unit 1, and the two ends of the spring 7 abut against the inner wall of the main unit 1 and the front end of the movable block 6, respectively. An opening slot 14 is provided on the rear side wall of the main unit 1; when the upper side of the connecting frame 2 is inserted into several slots 12, the trigger piece 21 abuts against the rear end of the movable block 6 and pushes the movable block 6 from back to front to trigger the trigger end 51 of the micro switch 5; when the connecting frame 2 is separated from the main unit 1, the spring 7 pushes the movable block 6 backward to reset it, thus releasing the trigger state of the micro switch 5; by adopting this triggering component and electronic control unit, the material bag and the main unit... After the machine is assembled, once the upper side of the connecting frame is inserted into several slots, the trigger plate abuts against the rear end of the movable block and pushes the movable block from back to front, causing the movable block to trigger the trigger end of the micro switch. At this time, the micro switch is turned on, allowing the main unit to be started. When the bladder is separated from the main unit, that is, after the connecting frame is separated from the main unit, the spring can push the movable block to move backward and reset, causing the movable block to release the trigger state of the micro switch. At this time, the micro switch is in an open circuit state, meaning the main unit cannot be started. In other words, the main unit cannot be started when the bladder is not installed, thus avoiding accidental start of the main unit and improving safety. In addition, the two ends of the spring are respectively engaged with the inner wall of the main unit and the front end of the movable block, thereby limiting the spring and preventing the spring from detaching from the main unit and the movable block.
[0030] The front end of the movable block 6 and the side facing the micro switch 5 are provided with an inclined surface 61. When the movable block 6 moves from back to front, the inclined surface 61 is used to cooperate with the trigger end 51 of the micro switch 5 for guidance so that the trigger end 51 of the micro switch 5 abuts against the outer wall of the movable block 6 facing the micro switch 5. With this structure, under the action of the inclined surface, when the movable block moves from back to front, the inclined surface can cooperate with the trigger end of the micro switch for guidance so that the trigger end of the micro switch abuts against the outer wall of the movable block facing the micro switch, thereby facilitating the movable block to trigger the trigger end of the micro switch to make the micro switch conduct.
[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
