Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage classification devices, in particular to the technical field of devices for separating garbage from garbage bags, and specifically to a flat-push bag breaking device. Background Art
[0002] Garbage classification generally refers to a series of activities that classify, collect, transport and process garbage according to certain regulations or standards, thereby transforming it into public resources.
[0003] The purpose of garbage classification is to increase the resource value and economic value of garbage, reduce the amount of garbage processed and the use of processing equipment, reduce processing costs, and reduce the consumption of land resources, which has social, economic, and ecological benefits. Garbage is a private property of the public during the classification and storage stage. After being classified and disposed of by the public, it becomes a regional public resource in the community or neighborhood where the public lives. After being classified and transported to garbage collection points or transfer stations, the garbage becomes a non-exclusive public resource. Judging from the methods of classifying domestic garbage in various cities at home and abroad, most of them are classified according to the composition and amount of garbage, combined with the local garbage resource utilization and treatment methods.
[0004] As for domestic waste, it can generally be divided into kitchen waste and other domestic waste. No matter what kind of waste it is, people are accustomed to pack and discard it in garbage bags or plastic bags, which makes the consumption of garbage bags / plastic bags very large. When classifying and processing garbage, plastic bags need to be separated from other garbage so that plastic waste can be disposed of harmlessly separately.
[0005] In the prior art, bag breaking equipment mostly adopts a shearing bag breaking method, specifically, a knife group or a similar structure is used to directly break the garbage, which is similar to the structure of a crusher. Although this method has a high bag breaking efficiency, it will also break and mix the garbage and the garbage bag at the same time when breaking the bag, which is not conducive to the subsequent garbage classification and cannot achieve the technical effect of garbage classification. For details, please refer to the garbage bag breaking machine technology provided by publication number CN214356851U. In order to better realize garbage classification, the present application provides a bag breaking technology that can separate garbage bags from garbage, and can completely separate garbage bags from garbage to facilitate subsequent garbage classification and processing.

[0010] Furthermore, the push-pull mechanism includes a cylinder B for pushing and pulling the first horizontal pushing unit and the second horizontal pushing unit, one end of the cylinder B is hinged with a connecting seat, and the connecting seat is fixedly installed on the sliding seat of the first horizontal pushing unit. One end of the push rod of the cylinder B is directly or through a variable amplitude mechanism connected to the sliding seat of the second horizontal pushing unit.
[0011] In order to facilitate the falling of garbage and avoid the problem of garbage deposition caused by excessive contact between the garbage and the bag breaking device, preferably, the angle between the planes on which the first push unit and the second push unit reciprocate is 90°-180°.
[0012] In order to more efficiently and thoroughly separate the garbage from the garbage bag, preferably, a shaking mechanism for rubbing / shaking the garbage bag is installed between the diversion inlet and the diversion outlet and is located above the bag breaking mechanism.
[0013] Further preferably, the vibration mechanism includes two flap mechanisms symmetrically installed on the outer shell, the flap mechanism includes a flap that performs linear reciprocating and up and down flipping compound motion, a cylinder mechanism hinged to the flap and drives the flap to perform reciprocating linear motion, and a pull rod mechanism hinged to the flap and flips the flap up and down when driven by the cylinder mechanism.
[0014] In order to better achieve vibration, preferably, the cylinder mechanism includes a cylinder A fixedly mounted on the outer shell, the free end of the push rod of the cylinder A is fixedly connected to a bracket, the two ends of the bracket are hinged to a hinge body fixedly connected to the flap, the two ends of the flap continue to extend along the width direction of the flap to form an ear piece for hinged to one end of the pull rod, and the other end of the pull rod is hinged to the outer shell.
[0015] In order to better adjust the flip angle of the flap, so as to adapt to the requirements of different sizes and different deflection amplitudes, preferably, the ear piece is vertically bent upward / downward relative to the plane where the flap is located, and then bent in the opposite direction to form an angle of 0°-45° with the plane where the flap is located, and the free end of the ear piece is bent to either side to form a tubular structure for hinge.

[0033] Embodiment 1:
[0034] This embodiment provides a push bag breaking device, see the attached manual Figure 1-Figure 7 As shown, it includes an outer shell 1, which has a diversion inlet 11 for garbage bags to be put in and a diversion outlet 12 for discharging garbage after the bags are broken, and a bag breaking mechanism 3 for tearing the garbage bags open so that the garbage can fall and separate naturally is installed between the diversion inlet 11 and the diversion outlet 12, and the bag breaking mechanism 3 includes a first horizontal push unit 31 and a second horizontal push unit 32 installed relatively, and a push-pull mechanism 33 for driving the first horizontal push unit 31 and the second horizontal push unit 32 to move closer to and separate from each other, and at least one end of the push-pull mechanism 33 is hinged to the first horizontal push unit 31 or the second horizontal push unit 32.
[0035] Working principle description:
[0036] In order to better understand the working principle of the bag breaking device provided in this embodiment, first, the working method of the prior art is briefly described: garbage bag breaking is a process in which the garbage bags are clamped and lifted one by one in the garbage sorting equipment, and then the garbage is subjected to operations such as shearing and tearing through the bag breaking mechanism, so that the garbage falls naturally from the garbage bag. There are various existing bag breaking mechanisms, but most bag breaking mechanisms for the purpose of garbage sorting are carried out in a tearing manner. In the prior art, the garbage bag containing garbage is transported to the top of the bag breaking device through a suspension mechanism, a guiding mechanism, or a clamping mechanism with different structures, and the garbage bag is torn by the bag breaking mechanism to achieve the purpose of breaking the bag and separating the garbage. The existing bag breaking mechanisms are different. The present embodiment provides a flat-push bag breaking device, which uses a tearing method to break the garbage bag. See. Figure 1-Figure 3 As shown, the garbage bag enters the outer shell 1 from the diversion inlet 11, and the bottom of the garbage bag is torn open by the bag-breaking mechanism 3 that repeatedly performs the horizontal push opening and closing action. After tearing open, the garbage in the garbage bag naturally falls from the diversion outlet 12 under the action of its own gravity, thereby achieving the purpose of separating the garbage from the garbage bag. The state in which the first horizontal push unit 31 and the second horizontal push unit 32 installed relatively close to each other is shown in FIG. Figure 7 As shown, at this time, the garbage bag is in contact with the bag breaking mechanism 3, and the garbage bag will be torn apart when the first horizontal pushing unit 31 and the second horizontal pushing unit 32 are separated, thereby achieving the purpose of breaking the bag. Figure 6 shown.
[0037] In order to better achieve complete bag breaking and avoid the problem of incomplete bag breaking and separation caused by the garbage bag being divided into multiple pieces, in this embodiment, the first push unit 31 and the second push unit 32 adopt a symmetrical structure. The first push unit 31 includes slide rails 311 arranged in parallel at both ends along the length direction of the first push unit 31, slide seats 312 slidingly arranged on the slide rails 311 at both ends, and crossbeams 316 fixedly connected to the slide seats 312 at both ends. A push plate 314 is fixedly installed on the crossbeam 316. The push plate 314 has a toothed structure 315 arranged upward on the side close to the second push unit 32. In this embodiment, the push plate 314 is fixedly connected by a sleeve 313 sleeved on the crossbeam 316, see Figure 6 For details, please refer to the appendix of the manual. Figure 6 and Figure 7 As shown, the tooth structure 315 is a key structure for tearing open the garbage bag. The tooth structure 315 hooks the garbage bag through the spike structure and plays a role of tearing it open during separation. The use of the slide rail 311 can accurately perform the action of approaching / separating. Due to the simple structure, it has high reliability and low failure rate.
[0038] In this embodiment, the push-pull mechanism 33 includes a cylinder B332 for pushing and pulling the first horizontal push unit 31 and the second horizontal push unit 32. One end of the cylinder B332 is hinged with a connecting seat 331. The connecting seat 331 is fixedly mounted on the slide 312 of the first horizontal push unit 31. One end of the push rod of the cylinder B332 is directly or through a variable amplitude mechanism 333 connected to the slide of the second horizontal push unit 32. It is worth noting that the present embodiment provides a garbage pushing mechanism 33 composed of a cylinder B, which is only one of the available methods. An eccentric disk and a connecting rod method can also be used to realize the conversion between rotational motion and reciprocating horizontal motion. The advantage of using the cylinder B332 for driving is more obvious. Compared with hydraulic pressure, the conversion of the mechanical connecting rod mechanism driven by the cylinder has the characteristics of large stroke, fast action, and low stress, which is very suitable for the application scenario of breaking garbage bags.
[0039] In order to facilitate the falling of garbage and avoid the problem of garbage deposition caused by excessive contact between the garbage and the bag breaking device, in this embodiment, the angle between the planes where the first push unit 31 and the second push unit 32 reciprocate is 90°-180°. That is, the first push unit 31 and the second push unit 32 are installed in a V-shape, and even if garbage splashes and falls on the push plate 314, it can fall with the inclined installation angle during the repeated approach and separation process, avoiding the accumulation of solid garbage and the deposition and adhesion of liquid garbage, thereby reducing the structural corrosion problem caused by garbage adhesion.
[0040] Embodiment 2:
[0041] This embodiment is further optimized based on the above embodiment 1. Figure 3-Figure 5 As shown, in order to more efficiently and thoroughly separate the garbage from the garbage bag, a shaking mechanism 2 for rubbing / shaking the garbage bag is installed between the diversion inlet 11 and the diversion outlet 12. The shaking mechanism 2 is used to rub and shake the torn garbage bag so that the garbage can be separated from the garbage bag more quickly to avoid garbage deposition.
[0042] In this embodiment, the shaking mechanism 2 includes two flap mechanisms symmetrically installed on the outer shell 1, and the flap mechanism includes a flap 25 that performs linear reciprocating and up and down flipping compound motion, a cylinder mechanism hinged to the flap 25 and drives the flap 25 to perform reciprocating linear motion, and a pull rod mechanism hinged to the flap 25 and drives the flap 25 to flip up and down under the drive of the cylinder mechanism.
[0043] In order to better achieve vibration, in this embodiment, Figure 4 and Figure 5As shown, the cylinder mechanism includes a cylinder A21 fixedly mounted on the outer shell 1, and the free end of the push rod 22 of the cylinder A21 is fixedly connected to a bracket 23. The two ends of the bracket 23 are hinged to a hinged body 251 fixedly connected to a flap 25, and the two ends of the flap 25 continue to extend along the width direction of the flap 25 to form an ear piece 252 for hingedly connecting to one end of the pull rod 26, and the other end of the pull rod 26 is hinged to the outer shell 1. Since the pull rod 26 is hinged to the ears 252 at both ends of the flap 25, and the hinged body 251 is hinged to the bracket 23 fixedly installed on the push rod 22, there is a spatial distance between the hinged position of the ear 252 and the hinged body 251, and the ear 252 is not arranged coplanar with the flap 25, so a torque will be generated, which makes the flap 25 produce an up and down deflection effect under the reciprocating push and pull action of the cylinder A21, so that the actual movement of the flap 25 is a combination of horizontal reciprocating linear motion and up and down deflection motion, which makes the external force acting on the garbage bag include horizontal squeezing and up and down shaking. Compared with the single shaking, it has a stronger shaking effect and is more conducive to the rapid falling of garbage.
[0044] In order to better adjust the flip angle of the flap 25 so as to meet the requirements of different sizes and different deflection amplitudes, preferably, the ear piece 252 is vertically bent upward / downward relative to the plane where the flap 25 is located, and then bent in the opposite direction to form an angle of 0°-45° with the plane where the flap 25 is located, and the free end of the ear piece 252 is bent to either side to form a tubular structure for hinge connection. The distance between the tubular structure for hinge connection of the ear piece 252 and the hinge body 251 of the flap 25 will affect the flip angle and torque of the flap 25. Under the same horizontal driving force, the larger the distance between the tubular structure for hinge connection of the ear piece 252 and the hinge body 251 of the flap 25, the smaller the driving force required and the smaller the flip angle; therefore, different distance sizes can be matched according to the actual driving force of the cylinder A21 to obtain a suitable flip angle and deflection amplitude.
[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
