DETAILED DESCRIPTION

[0035] The core of the present invention is to provide a sanitation equipment and a packing compression mechanism thereof to solve the problem that garbage trucks are prone to secondary leakage and secondary pollution.

[0036] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1-Figure 7As shown, a filler compression mechanism of a sanitation equipment provided by an embodiment of the present invention includes a scraper plate mechanism and a push shovel mechanism. The scraper plate mechanism includes a scraper 1 and a scraper driving mechanism 4 for driving the scraper 1 to deliver garbage in a feeding port 2 into a garbage bin 3. The end of the scraper 1 is used to cooperate with an inclined surface 21 of the feeding port 2, and the side of the scraper 1 facing the inside of the garbage bin 3 is a concave arc surface; the push shovel mechanism includes a push-pull rod 5 arranged in the garbage bin 3 and connected to the front inner wall of the garbage bin 3, and a push shovel 6 fixedly arranged at the end of the push-pull rod 5, and the push shovel 6 includes a push-pull rod 5 and a push-pull rod 5. An upper sealing plate 61 fixedly connected to the end of the push-pull rod 5, a lower sealing plate 62 hinged to the lower part of the upper sealing plate 61, and a sealing plate driving mechanism for driving the lower sealing plate 62 to rotate around its hinge axis on the upper sealing plate 61 to open and close the lower sealing plate 62; and when the scraper 1 moves along the inclined surface 21 of the feeding port 2, the lower sealing plate 62 is opened; when the scraper 1 moves to the end of the inclined surface 21 of the feeding port 2, the sealing plate driving mechanism drives the lower sealing plate 62 to rotate and close, and when the lower sealing plate 62 rotates, the end of the lower sealing plate 62 moves close to the curved surface of the scraper 1.

[0038] In the actual working process of the filler compression mechanism, after the garbage is fed into the feeding port, the scraper is driven by the scraper driving mechanism to feed the garbage into the garbage bin, and when the scraper moves along the inclined surface of the feeding port, it is in an open state; when the scraper moves to the end of the inclined surface of the feeding port, the sealing plate driving mechanism drives the lower sealing plate to rotate, and when the lower sealing plate moves to a closed state, the push-pull rod drives the upper sealing plate to make a linear pulling motion, thereby completing the garbage compression process. In this process, since the side of the scraper facing the inside of the garbage bin is a concave arc surface, and the end of the lower sealing plate moves closely against the arc surface of the scraper, the scraper plate mechanism and the push shovel mechanism can ensure that there is basically no gap in the connection operation during the operation connection, thereby avoiding the problem of secondary leakage of garbage and sewage through the gap during the connection operation to form secondary pollution. In addition, since the push-pull rod used to drive the push shovel is located in the garbage bin, compared with the traditional design of the push shovel mechanism at the front end of the garbage truck, the space occupied by the push shovel mechanism can be greatly reduced, and the space utilization rate of the whole vehicle can be improved.

[0039] It should be noted that the closing process of the lower sealing plate is as follows: the lower sealing plate is lowered and forms a seal with the concave arc surface of the scraper to push the garbage into the interior of the garbage bin, and after the lower sealing plate is lowered to the lowest position, it forms a seal with the bottom surface of the garbage bin to seal the garbage in the garbage bin. When filling is required, the lower sealing plate is flipped up to the highest position again and is in an open state. It should also be noted that those skilled in the art should be able to understand that the push-pull rod is a component that can undergo telescopic movement, and the telescopic movement of the push-pull rod can drive the push shovel fixed at the end of the push-pull rod to perform reciprocating linear motion. Specifically, the method of driving the cylinder arm by an oil cylinder can be adopted. Since the push-pull rod is located inside the garbage bin, in order to prevent the oil cylinder from being contaminated and corroded, a sealing sleeve 51 structure is generally provided on the outside of the oil cylinder, and the sealing sleeve 51 is generally fixed to the upper sealing plate by welding, and in order to ensure the stability of the upper sealing plate, a connecting rib is also provided between the upper sealing plate and the sealing sleeve.

[0040] In some specific implementation schemes, the sealing plate driving mechanism may specifically include a sealing plate driving arm 63a whose two ends are respectively hinged on the upper sealing plate 61 and the lower sealing plate 62, and the telescopic movement of the sealing plate driving arm 63a can drive the lower sealing plate 62 to rotate around its hinge axis on the upper sealing plate 61. It should be noted that the sealing plate driving arm may specifically be a cylinder telescopic arm, or it may be other telescopic rod structures commonly used by those skilled in the art, and no specific limitation is made here. Of course, it can be understood that the above-mentioned method of using the sealing plate driving arm is only a preferred example of the embodiment of the present invention. In actual application, other driving and rotating mechanisms commonly used by those skilled in the art may also be used, such as the lower sealing plate is fixedly connected to the hinge axis, and the motor drives the gear, chain or belt to drive the hinge axis to rotate, etc.

[0041] In a further embodiment, the sealing plate driving mechanism may further include a telescopic rod mechanism 63b coaxially arranged with the push-pull rod 5, and the end of the telescopic rod of the telescopic rod mechanism 63b is hinged to the oil cylinder of the oil cylinder telescopic arm. By providing the telescopic rod mechanism and hinged to the oil cylinder of the oil cylinder telescopic arm, a rotational torque can be provided when the lower sealing plate switches from the closed state to the open state, thereby avoiding the stuck phenomenon that is easy to occur when the sealing plate driving arm is used alone.

[0042] In some specific embodiments, the scraper driving mechanism 4 may specifically include a slide 41 fixedly set on the garbage truck and arranged in the up and down direction, a slide plate 42 slidably matched with the slide 41, and a slide plate driving mechanism 44 for driving the slide plate 42 to move along the slide 41. The starting end of the scraper 1 is hinged to the slide plate 42, and a scraper rotating mechanism is arranged between the slide plate 42 and the scraper 1 for driving the scraper to rotate around its hinge axis on the slide plate 42; the slide plate is driven to slide along the slide by the slide driving mechanism, and then the scraper hinged on the slide plate can be driven to move up and down as a whole. When the slide plate 42 moves to the upper position of the slide 41, the scraper 1 is disengaged from the inclined surface of the feeding port 2, and when the slide plate 42 moves to the lower position of the slide 41, the scraper 1 is matched with the inclined surface of the feeding port 2. It should be noted that the scraper will also rotate under the drive of the scraper rotation mechanism during the lifting process, and technical personnel in this field should be aware that in order for the scraper to scrape the garbage smoothly, it needs to cooperate with the inclined surface of the feeding port. Therefore, the inclined surface of the feeding port should be an arc surface with the same arc-shaped surface as the up and down flipping motion trajectory of the scraper.

[0043] In a further embodiment, the scraper blade rotation mechanism may be a telescopic arm 43, and the two ends of the telescopic arm 43 are respectively hinged to the slide plate 42 and the scraper blade 1. Of course, it can be understood that the structure of the telescopic arm is only a preferred example of the scraper blade rotation mechanism in the embodiment of the present invention. In actual application, other driving and rotating mechanisms commonly used by those skilled in the art may also be used, such as a scraper blade fixedly connected to its hinge shaft on the slide plate, a motor driving a gear, a chain or a belt to drive the hinge shaft to rotate, etc.

[0044] In some more specific embodiments, such as Figure 6 and Figure 7As shown, guide sliders 7 are also provided on both sides of the above-mentioned slide plate 42, and the guide sliders 7 are slidably matched with the slide groove 41, and the guide sliders 7 include a first slider 71 slidably matched with the groove wall on one side of the slide groove 41 and a second slider 72 slidably matched with the groove wall on the other side of the slide groove 41. The first slider 71 and the second slider 72 are symmetrically arranged along the slide groove 41, and there is a compensation gap between the first slider 71 and the second slider 72. Fixing holes 73 are provided on the first slider 71 and the second slider 72. The fixing holes 73 are fixedly connected to the side end surface of the slide plate 42 by bolts 74, and the fixing holes 73 are waist-shaped holes arranged along the extension direction perpendicular to the slide groove 41. During the actual working process of the guide slider, the first slider and the second slider are respectively slidably matched with the groove walls on both sides of the slide groove, and the first slider and the second slider are respectively fixed to the side ends of the slide plate by bolts. Then, when the driving mechanism of the slide plate drives the slide plate, under the sliding cooperation between the guide slider and the slide groove, the slide plate can move along the direction of the slide groove; when the first slider and the second slider are worn, since there is a compensation gap between the first slider and the second slider, and the fixing holes on the first slider and the second slider are waist-shaped holes arranged perpendicular to the extension direction of the slide groove, the bolts on the fixing holes are loosened to make the first slider and the second slider move respectively toward the groove wall direction of the corresponding slide groove, so as to compensate for the wear without replacing the guide slider, which greatly prolongs the service life of the guide slider, avoids frequent replacement of the guide slider, and reduces maintenance costs.

[0045] In a further embodiment, the guide slider 7 may further include two wedge blocks 75 respectively matched with the openings at both ends of the compensation gap, and the slide plate 42 is provided with support plates 76 arranged facing the end surfaces of the guide slider 7, and the support plates 76 are provided with tightening screws 77 for tightening the wedge blocks 75 against the end openings of the compensation gap. When the first slider and the second slider are worn, the positions of the bolts and the fixing holes are adjusted so that the first slider and the second slider are respectively close to the groove wall of the corresponding side of the slide groove and the bolts are locked, and then the wedge blocks are tightened by the tightening screws, so that the gap amount of the compensation gap can be controlled at a fixed position, and then the first slider and the second slider are further ensured to be closely matched with the groove wall of the slide groove, so that the guide slider is prevented from shaking relative to the slide groove as a whole, and the stability of the sliding fit is ensured.

[0046] In a further embodiment, the specific structure of the sliding cooperation between the first slider 71 and the second slider 72 and the groove wall of the corresponding side of the slide groove can be that the first slider 71 and the second slider 72 are both provided with a U-shaped slide groove that matches the groove wall of the corresponding side of the slide groove 41. The sliding cooperation between the U-shaped slide groove and the groove wall makes the cooperation between the slider and the slide groove more stable and reliable. Of course, it can be understood that the above-mentioned structure of providing a U-shaped slide groove on the first slider and the second slider is only a preferred example of the embodiment of the present invention. In actual application, U-shaped slide grooves can also be provided on the groove walls on both sides of the slide groove, and the first slider and the second slider are respectively provided with a protruding structure matching the U-shaped slide groove on the corresponding side, or other sliding cooperation structures commonly used by those skilled in the art.

[0047] It should be noted here that the guide slider 7 is generally selected to be a guide slider made of elastic material. By setting it to an elastic material, after adjusting the compensation gap, the tightness of the fit between the guide slider and the groove wall of the slide groove is easier to ensure. And for the selection of elastic material, the guide slider 7 can be specifically designed to be a guide slider made of nylon or rubber material. Of course, it can be understood that the guide slider made of nylon or rubber material is only a preferred example of the embodiment of the present invention. In actual application, other elastic materials or non-elastic materials commonly used by technicians in this field can also be selected.

[0048] In some more specific embodiments, such as Figure 5 As shown, the end of the scraper 1 can also be provided with an elastic abutment 8, and when the scraper 1 is matched with the inclined surface of the feeding port 2, the end of the elastic abutment 8 is always sealed against the inclined surface of the feeding port 2. In this way, in the actual working process, when the garbage truck adopts the above-mentioned scraper structure, since the end of the scraper is provided with an elastic abutment, when the scraper is matched with the inclined surface of the feeding port, the end of the elastic abutment is always sealed against the inclined surface of the feeding port. Since the elastic abutment has a certain elasticity, there is no problem of jamming, and it will not affect the normal rotation of the scraper. In addition, through the structure of the elastic abutment and the inclined surface of the feeding port being sealed against each other, the situation of garbage and sewage leaking through the matching position of the scraper and the feeding port and polluting the environment again is avoided, eliminating the trouble of garbage collection and transportation. In addition, due to the use of the elastic abutment, when the end of the elastic abutment is worn, it can automatically compensate, ensuring that the matching of the elastic abutment and the inclined surface of the feeding port is always in a sealed state, effectively ensuring the reliability of the seal.

[0049] In some specific embodiments, the specific structure of the elastic abutment 8 may include a groove 81 provided at the end of the scraper 1 and a friction plate 82 embedded in the groove 81, wherein the friction plate 82 and the groove 81 are slidably matched in a direction perpendicular to the groove bottom of the groove 81, and an automatic pre-tightening mechanism is provided between the friction plate 82 and the groove bottom of the groove 81, and the automatic pre-tightening mechanism is used to keep the friction plate 82 always in a tendency to extend. The automatic pre-tightening mechanism allows the friction plate to always maintain a tendency to extend toward the inclined surface of the upper feed port, thereby achieving the effect of elastic abutment, and thereby ensuring the sealing of the elastic abutment without affecting the rotation of the scraper body. Moreover, when the end of the friction plate is worn, it can automatically compensate to ensure that the end of the friction plate of the elastic abutment and the inclined surface of the feed port are always in a sealed state, thereby effectively ensuring the reliability of the seal.

[0050] It should be noted here that the specific structure of the automatic pre-tightening mechanism can be a compression spring 83, one end of which is in contact with the bottom of the groove, and the other end of which is in contact with the end surface of the friction plate 82 facing the bottom of the groove; the automatic pre-tightening mechanism can also be a cylinder connecting arm, one end of which is connected to the bottom of the groove, and the other end of which is connected to the friction plate 41. By filling the cylinder connecting arm with a certain pressure of gas, the cylinder connecting arm always has a tendency to extend out and resist against an inclined surface of the friction plate facing the upward feed port. Of course, it can be understood that the above two methods are only preferred examples of the automatic pre-tightening mechanism of the present invention. In actual application, other automatic pre-tightening mechanisms commonly used by technicians in this field can also be selected.

[0051] It should also be noted that the above-mentioned friction plate is preferably made of elastic material, for example, it can be made of nylon or rubber material. Of course, it can be understood that the above-mentioned nylon or rubber material is only a preferred example of the friction plate material in the embodiment of the present invention. In actual application, other elastic materials or non-elastic wear-resistant materials commonly used by technical personnel in the field can also be selected to make a friction plate.

[0052] In a further embodiment, in order to more effectively avoid the occurrence of secondary leakage, the structure in which the scraper cooperates with the feeding port is preferably provided with sealing strips at both ends of the scraper 1 for sealing with the two side surfaces of the feeding port 2. This can ensure the multi-directional sealing when the scraper cooperates with the feeding port, and more effectively avoid the occurrence of secondary leakage.

[0053] In addition, the present invention also provides a sanitation equipment, including a packing compression mechanism, and the packing compression mechanism is the packing compression mechanism described in any of the above schemes. Since the above packing compression mechanism has the above technical effects, the sanitation equipment having the above packing compression mechanism should also have corresponding technical effects, which will not be repeated here.

[0054] The above is a detailed introduction to the sanitation equipment and the packing compression mechanism provided by the present invention. It should be noted that each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other.
