Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household garbage transfer mechanical equipment, and particularly relates to a pushing head mechanism for preventing garbage from being brought back and a household garbage compressor. BACKGROUND

[0002] The horizontal split type household garbage compressor is divided into a compression cavity and a rear support in the length direction, and its working principle is to rely on the reciprocating movement of the pushing head mechanism to compress and reduce the volume of the loose garbage in the compression cavity, so that the garbage can be efficiently transferred. Since the pushing head mechanism is a moving mechanism, there is relative movement between the pushing head mechanism and the compression cavity, and a reasonable matching gap is inevitably arranged between the two to ensure that the pushing head mechanism can smoothly perform the reciprocating compression action.

[0003] However, due to the existence of the matching gap, some fine garbage will adhere to the surface around the pushing head during the reciprocating compression of the pushing head, and will be brought back to the rear support. When the pushing head advances again to compress the garbage, the newly poured loose garbage in the compression cavity will push the fine garbage originally adhered to the surface around the pushing head backward, so that the fine garbage will fall off at the rear support.

[0004] The pushing head and the inner wall of the compression cavity mainly rely on the sliding block for contact. During long-time movement, the sliding block gradually wears out, so that the matching gap between the two gradually increases, more fine garbage adhered to the surface around the pushing head is brought back to the rear support, and problems such as unstable movement of the pushing head and increased noise may occur. Long-term accumulation will cause excessive accumulation of garbage at the rear support of the compressor.

[0005] The structure at the rear support is often complex, and is the place where the oil cylinder, valve group, sensor, hydraulic oil circuit and electrical harness of the compressor are arranged. The accumulation of garbage at this place will affect the cleanliness of the hydraulic oil circuit and the detection accuracy of the sensor. For example: ① pollution of the hydraulic oil circuit will cause blockage of the valve group, scratching of the oil cylinder barrel, and oil cylinder leakage; ② the shielding of garbage will cause the proximity switch and the laser distance measuring sensor to fail to detect the movement position of the pushing head, and thus cause the equipment to stop working and other problems; the resulting stoppage, maintenance and replacement of parts will seriously affect the transfer efficiency of the household garbage transfer station and increase the labor intensity of the staff at the station.

[0006] The fine garbage is mixed with leachate, has strong adhesion, and it is difficult for cleaning personnel to enter and clean due to the limited space and the large number of components arranged at the rear support. When the garbage accumulates to a certain amount, it will cause foul odor around the compressor, attracting harmful mosquitoes and other problems.

[0007] Therefore, in the technical field of household garbage compressors, how to effectively reduce the fine garbage brought back to the rear support of the compressor is a technical problem to be solved. SUMMARY

[0008] The purpose of the present application is to overcome the deficiencies in the prior art, provide a push head mechanism for preventing garbage back and a domestic garbage compressor, the gap between the push head and the compression chamber is sealed, which maximizes the prevention of fine garbage from being brought back to the rear support through the gap, and the convenience of the slider installation, disassembly, maintenance and replacement is considered, so that the replacement can be quickly operated and responded, and the decrease of the transfer efficiency in the station caused by maintenance downtime is reduced.

[0048] It should be noted that: similar labels and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0049] Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0050] As shown in Figure 1 An embodiment of the present application provides a push head mechanism for preventing garbage backtracking, the push head mechanism is limited in a compression cavity, the push head mechanism is initially located at one side of the compression cavity, a discharge port is formed at the other side of the compression cavity, the push head mechanism reciprocates between the initial position and the discharge port, and the compression cavity is provided with a feeding port at the top far away from the discharge port.

[0051] The push head mechanism for preventing garbage backtracking comprises: a push head body 1; a first sealing mechanism 24 comprising a first pre-stress mechanism and a first sliding block 2, as Figure 1As shown, the first prestressing mechanism is installed on both sides and the bottom of the pusher body 1, and the first slider 2 is installed on the outside of the first prestressing mechanism relative to the pusher body 1. The second sealing mechanism 25 includes a second prestressing mechanism and a second slider 3. The second prestressing mechanism is located on the side of the feeding port away from the discharging port, and the second slider 3 is installed on the second prestressing mechanism. The first slider 2 and the second slider 3 are both used to fill the gap between the pusher body 1 and the compression chamber.

[0052] like Figures 2-5 As shown, in one embodiment of the present invention, the first prestressed mechanism includes: a limit seat 4, which is arranged on both side edges and the bottom edge of the push head body 1, including a first fixed limit seat 5, a second fixed limit seat 6 and a movable limit seat 7, the first fixed limit seat 5 and the second fixed limit seat 6 are parallel to each other and fixedly connected to the push head body 1, the movable limit seat 7 is detachably connected to the first fixed limit seat 5 and the second fixed limit seat 6, a first opening 8 is provided between the first fixed limit seat 5 and the movable limit seat 7, and a second opening 9 is provided between the second fixed limit seat 6 and the movable limit seat 7; the pushing mechanism includes a push plate 10 and a push rod 11 The push rod 11 is perpendicular to the push plate 10 and is fixedly connected to the push plate 10. The push rod 11 is installed in the first opening 8 and the second opening 9; the first spring 12 is sleeved on the outside of the push rod 11, one end abuts on the push plate 10, and the other end abuts on the outer contour of the second opening 9. The diameter of the first opening 8 is larger than the diameter of the first spring 12, and the diameter of the second opening 9 is smaller than the diameter of the first spring 12. The first opening 8 and the push rod 11 guide the first spring 12 to prevent deflection; the first fastening mechanism 13 is installed at the free end of the push rod 11, located on the side of the second opening 9 away from the first opening 8, and is used to apply preload force to the first spring 12.

[0053] One end of the first spring 12 is fixedly limited on the outside of the second opening 9, and the other end rests on the push plate 10. Under the action of the elastic force of the first spring 12, the push plate 10 can push the first slider 2, always resting on the inner wall of the compression chamber, preventing fine garbage from adhering to the surface of the push head and being brought back to the rear bracket.

[0054] The first sealing mechanism 24 provided in the embodiment of the present invention is convenient for disassembling the slider. The replacement method is: after removing the fixing bolts between the first fixed limit seat 5, the second fixed limit seat 6 and the movable limit seat 7, the movable limit seat 7 can be conveniently removed, and then the first fastening mechanism 13 on the push plate 10 is tightened to retract the push plate 10 to the side away from the inner wall of the compression chamber, the old slider is pulled out from between the push plate 10 and the inner wall of the compression chamber, and then the new slider is put in, and then the disassembled mechanisms are installed in turn.

[0055] like Figure 6 and Figure 7As shown, in one embodiment of the present invention, the second prestressing mechanism includes:

[0056] The mounting seat 14 is installed on the side of the feeding port away from the discharging port, and includes a mounting plate 15 and a support rod 16. The support rod 16 is fixed to the top of the mounting plate 15 perpendicular to the mounting plate 15, and the second sealing mechanism 25 is installed on the compression chamber through the mounting plate 15; the spring limiting plate 17 is installed on the top of the mounting seat 14, and a through hole is opened on the spring limiting plate 17, and the support rod 16 passes through the through hole; the second spring 18 is sleeved on the outside of the support rod 16, one end abuts against the mounting plate 15, and the other end abuts against the bottom of the spring limiting plate 17; the second fastening mechanism 19 is installed at the free end of the support rod 16, located at the top of the spring limiting plate 17, and is used to apply pre-tightening force to the second spring 18.

[0057] One end of the second spring 18 is limited by the spring limit plate 17, and the other end pushes the mounting seat 14, so that the second slider 3 can always abut against the upper surface of the pusher head body 1 under the action of elastic force, preventing fine garbage from adhering to the upper surface of the pusher head body 1 and being brought back to the rear bracket (the gap between the upper surface of the pusher head and the inner wall of the compression chamber is larger than that of the other three surfaces. When the collection vehicle is feeding, the loose garbage will first contact the upper surface of the pusher head after falling. Therefore, the possibility of fine garbage being brought back to the rear bracket from the upper part of the pusher head is the greatest).

[0058] like Figure 8 As shown, the mounting plate 15 includes a base plate 20 , a pressing plate 21 and a fastener 22 ; the second slider 3 is clamped between the base plate 20 and the pressing plate 21 and fixed by the fastener 22 .

[0059] In one embodiment of the present invention, a support seat 23 is further included for installing a second prestressed mechanism; the support seat 23 is an L-shaped support seat 23, one end of which is connected to the inside of the top of the compression chamber, located on the side of the feeding port away from the discharging port, and the other end is connected to the side of the base plate 20.

[0060] The second prestressing mechanism provided in the embodiment of the present invention can replace the second slider 3 without disassembling the second sealing mechanism 25. The steps are as follows:

[0061] a. Tighten the second fastening mechanism 19 to increase the compression of the second spring 18, causing the mounting seat 14 and the second slider 3 to retract upward, and the second slider 3 to separate from the upper surface of the pusher head body 1;

[0062] b. Remove the pressing plate 21 and take out the second slider 3;

[0063] c. A sliding groove is reserved on the upper side plate of the compression chamber. When the second sealing mechanism 25 is working, the second slider 3 is pressed on the push head body 1 through the sliding groove. The width of the sliding groove is larger than the width of the second slider 3. The new slider can be tilted and lowered into the sliding groove. After the slider is placed, the pressure plate 21 is reinstalled to complete the replacement of the new slider.

[0064] In one embodiment of the present invention, the first fastening mechanism 13 and the second fastening mechanism 19 are limit nuts, and the first slider 2 and the second slider 3 are made of nylon or high molecular polyethylene.
