Description

[0003] At present, the feeding hopper structure and the overturning structure of the mobile garbage compression equipment are known, and the length of the existing feeding hopper butt joint part has tended to be consistent under the condition of the limitation of the width of the feeding hopper and the premise that garbage cannot be scattered in advance when the whole feeding hopper is lifted and overturned, which leads to the fact that the unloading operation cannot be met when the tipping mechanism of the feeding vehicle is opened, and the above butt joint condition is often encountered in actual use, so that the tipping mechanism can only be opened in advance to butt joint, resulting in garbage overflow, secondary pollution and additional manual labor, limiting the range of butt joint vehicles and increasing the labor intensity.

[0016] As a further improvement, the connecting structure is a push rod motor, and the fixed end and the output end of the push rod motor are connected with the first hinged seat and the second hinged seat respectively.

[0017] The present application has the following advantages:

[0018] The present application adds a self-adaptive transformation backplate assembly to the traditional feeding structure, and the self-adaptive transformation backplate assembly has two working states:

[0019] The first state is that the garbage transfer vehicle is in a feeding state, at this time, the rotating shaft is not rotating, the side baffle and the extended backplate are fixed by the coordination of their own gravity and gravity center, and the limiting relationship is maintained, so that a certain angle is presented, which does not affect the lifting of the filler of the incoming vehicle, and can collect the scattered garbage to prevent overflow, and expand the garbage feeding depth of the existing feeding hopper.

[0020] The second state is that the feeding hopper is in a turnover state, when the feeding hopper is turned over to dump garbage, the rollers on the side baffle will slide down along the guide inclined plate of the garbage compression box, and act on the side baffle in the opposite direction to change the position of the side baffle and the extended backplate, so that the extended backplate can push the garbage accumulated on the guide inclined plate to the center for compression processing, so that the extended backplate can block in the feeding stage and tilt and guide in the discharging stage, which can not only ensure the normal dumping demand of the hopper, but also increase the tonnage range of the docking vehicle, improve economic benefits, reduce labor intensity, reduce manual work after garbage overflow, and avoid secondary pollution.

[0021] After the feeding hopper dumps the garbage, it needs to fall back, and the side baffle and the extended backplate also need to turn over and fall back during the falling back process. However, in fact, due to the heavy weight of the entire self-adaptive transformation backplate assembly, sometimes although the feeding hopper is reset, the gravity center of the self-adaptive transformation backplate assembly is still not reset, and the entire self-adaptive transformation backplate assembly cannot be reset, so that it cannot limit and guide the next dumping of garbage. To this end, the present application adds a reset cycle assembly, which can monitor the movement position of the side baffle, so as to judge whether the entire self-adaptive transformation backplate assembly is reset to the original position. When the side baffle is not reset to the original position, the side baffle is automatically pulled back to the original position by the back swing piece, so as to avoid the garbage overflow phenomenon caused by the self-adaptive transformation backplate assembly not resetting in time, and the workers do not need to be on site on patrol all the time, reducing the labor intensity of the workers.

[0022] In order to reduce the space ratio of the roller, avoid the influence of the falling garbage on the roller in the use process, the position of the roller is arranged at two top corners of the extended back plate, and an embedded type is adopted, so that the possibility of direct contact with the garbage is reduced. Further, in order to ensure the turnover degree of the roller and prevent the roller from being blocked by the garbage between the roller and the fixed part, a shielding plate is arranged on the side of the roller facing the garbage input direction, and the shielding plate is used to block the garbage that may directly act on the roller.

[0023] The upper hopper in the application is also different from the upper feeding structure in the prior art. First, since the rear half of the upper hopper needs to be turned to the feeding position of the compression equipment, the actual size is fixed, that is, the size of the back baffle and the first side support plate is fixed. However, in order to facilitate the docking with the garbage transfer vehicle, improve the accuracy of docking, and avoid garbage overflow, the front half of the upper hopper is expanded outward after being inclined through an expansion plate in the application, so that the distance between the two second side support plates is greater than the distance between the two first side support plates, so that the garbage truck can enter the upper hopper more deeply and better cooperate with the upper hopper. Due to the setting of the self-adaptive transformation back plate assembly, even if the garbage transfer vehicle enters a distance, garbage overflow is not easy to occur.

[0024] In the initial stage of the inductor, the first inductor sheet and the second inductor sheet in the inductor do not have any contact with the side baffle. After the side baffle is turned, it is in contact with the first inductor sheet and the second inductor sheet. If the side baffle is not reset in place, only the first inductor sheet will generate a signal. When the first inductor sheet generates a signal, it indicates that the entire self-adaptive transformation back plate assembly is in the middle position and has not been reset in place. Therefore, the swing piece will be self-started only when the first inductor sheet is triggered, driving the entire side baffle to a position where the first inductor sheet cannot be triggered, so as to ensure that the entire self-adaptive transformation back plate assembly can be reset in place, and still has a large range of receiving space for the next feeding.

In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0039] Referring to Figures 1-5 As shown in the drawings, a feeding mechanism includes a connecting foot 10 rotatably mounted on a garbage compression box 20 by a driving member, the connecting foot 10 is fixedly connected in a feeding hopper 30, the feeding hopper 30 is used to carry the garbage dumped by the garbage transfer vehicle, the feeding mechanism further comprises: an adaptive transformation backplate assembly, a guide inclined plate 21 is arranged on the side of the garbage compression box 20 close to the garbage transfer vehicle, the adaptive transformation backplate assembly comprises two rotating shafts 41 rotatably mounted on the inner side wall of the feeding hopper 30, a side baffle 42 is rotatably mounted on the outer side of the rotating shaft 41, the side baffle 42 is attached to the inner side wall of the feeding hopper 30, an extension backplate 43 is welded between the two side baffles 42, at least two rollers 45 are locked on the top of the extension backplate 43 by a fixing member 44, when the feeding hopper 30 rotates along the garbage compression box 20 under the action of the driving member, the center of gravity of the adaptive transformation backplate assembly changes and overturns with the rotating shaft 41 as the center, the rollers 45 slide along the guide inclined plate 21 and change the inclination angle of the extension backplate 43; a reset cycle assembly comprises a side bracket located on the inner side wall of the feeding hopper 30, the side bracket abuts against the side baffle 42, an inductive member 511 is arranged inside the side bracket and faces the side baffle 42, a backswing member 52 is further arranged on the side wall of the feeding hopper 30, when the side baffle 42 is in place, the inductive member 511 senses that the mechanism is in the first working condition, when the side baffle 42 is overturned by the rollers 45 under the action of the guide inclined plate 21, the inductive member 511 senses that the mechanism is in the second working condition, when the side baffle 42 does not accurately switch from the second working condition to the first working condition, the backswing member 52 drives the side baffle 42 to reset to the first working condition.

[0040] At the position of the garbage compression box 20, in order to facilitate the garbage to fall in, a funnel-shaped structure is usually designed, that is, a guide inclined plate 21 is arranged on one side.

[0041] In the embodiment, the garbage is poured into the feeding hopper 30 by the garbage transfer vehicle, and the whole connecting foot stand 10 is rotated by the overturning of the driving member, so that the feeding hopper 30 connected with the connecting foot stand 10 is rotated, wherein the driving member is a hydraulic cylinder, and can also be other driving structures.

[0042] The feeding structure in the embodiment only adjusts the top position of the feeding hopper 30, cancels part of the top of the back plate of the existing feeding hopper 30, and replaces it with a new adaptive transformation back plate assembly. The adaptive transformation back plate assembly is provided with an extension back plate 43, a side baffle 42 and a rotating shaft 41. The adaptive transformation back plate assembly can completely replace the function of the original back plate to prevent the garbage from falling down in advance during the whole lifting and overturning. The rotating shaft 41 is arranged on the left and right two side baffles 42 and is limitedly arranged at the bottom of the adaptive transformation back plate assembly to form a limiting relationship with the back of the feeding hopper 30. The adaptive transformation back plate assembly is added on the basis of the traditional feeding structure, and has two working states:

[0043] The first state is that the garbage transfer vehicle is in a feeding state. At this time, the rotating shaft 41 is not rotated, the side baffle 42 and the extension back plate 43 are fixed by the coordination of their own gravity and gravity center, and the limiting relationship is maintained all the time to present a certain angle, which does not affect the lifting of the filling device of the feeding vehicle and can collect the scattered garbage to prevent overflow and expand the garbage feeding depth of the existing feeding hopper.

[0044] The second state is that the feeding hopper 30 is in an overturning state. When the feeding hopper 30 is overturned to dump garbage, the rollers 45 on the side baffles 42 will slide down along the guide inclined plate 21 of the garbage compression box 20 and act on the side baffles 42 in the opposite direction to change the position of the side baffles 42 and the extension back plate 43, so that the extension back plate 43 can push the garbage accumulated on the guide inclined plate 21 to the center position, which is beneficial to compression processing, so that the extension back plate 43 can block in the feeding stage and can be inclined and guided in the discharging stage. It can not only meet the needs of normal hopper garbage dumping, but also increase the tonnage range of the docking vehicle, improve economic benefits, reduce labor intensity, reduce manual work after garbage overflow, and avoid secondary pollution.

[0045] In the specific use process, the upper hopper 30 needs to fall back after dumping garbage, and the side baffle 42 and the extension back plate 43 also need to turn back during the falling back process. However, in fact, due to the heavy weight of the entire adaptive transformation back plate assembly, sometimes although the upper hopper 30 is reset, the center of gravity of the adaptive transformation back plate assembly is still not reset, and the entire adaptive transformation back plate assembly cannot be reset, so that it cannot limit and guide the new dumping of garbage. The prior art usually solves this problem by manually patrolling the work point. When it is found that the adaptive transformation back plate assembly is not automatically reset, it is reset by manually turning it. To this end, the present application can monitor the movement position of the side baffle 42 by adding a reset cycle assembly, so as to judge whether the entire adaptive transformation back plate assembly is reset to the original position. When the side baffle 42 is not reset to the original position, the side baffle 42 is automatically pulled back to the original position by the back swing piece 52, so as to avoid the phenomenon of garbage overflow caused by the fact that the adaptive transformation back plate assembly is not reset in time, and manual on-site patrol is not required, thereby reducing the labor intensity of workers.

[0046] Since the side bracket is arranged on the inner side wall of the upper hopper 30, there is a risk that garbage will fall into it, thereby squeezing the accommodation space of the side baffle 42. To this end, the side bracket adopts a semi-enclosed design, that is, a closed arrangement is adopted on the side facing the garbage, and only the movement space of the side baffle 42 is left on the side facing the side baffle 42, so as to avoid the interference of a part of the garbage flowing into the side bracket with the monitoring effect.

[0047] In order to reduce the space ratio of the roller 45 and avoid the influence of the falling garbage on the roller 45 during use, two top corners of the extension back plate 43 are cut to form notches, a matching hole is drilled in the inner side wall of the notch, the roller 45 is arranged in the notch, and the fixing piece 44 penetrates the roller 45 and is inserted into the matching hole, so as to set the position of the roller 45 at the two top corners of the extension back plate 43, and adopt an embedded type, thereby reducing the possibility of direct contact with garbage. Further, in order to ensure the rotation degree of the roller 45 and prevent the roller 45 and the fixing piece 44 from being blocked by garbage, preferably, the side of the roller 45 facing the garbage input direction is provided with a shielding plate 46, and the shielding plate 46 is inclinedly welded on the extension back plate 43. The shielding plate 46 is used to block the garbage that may directly act on the roller 45.

[0048] The upper hopper 30 in the present invention is also different from the feeding structure in the prior art. First, since the upper hopper 30 in the rear half needs to be flipped to the feeding position of the compression equipment, its actual size is fixed, that is, the size of the back baffle 31 and the first side support plate 33 is fixed. However, in order to facilitate docking with the garbage transfer vehicle, improve the accuracy of docking, and avoid garbage overflow, the upper hopper 30 in this embodiment includes a back baffle 31 welded to the connecting bracket 10, a lower base plate 32 is welded to the bottom of the back baffle 31, and first side support plates 33 are welded on both sides of the back baffle 31. The first side support plate 33 extends outward. An outward expansion plate 34 is provided, and a second side support plate 35 is welded to the side of the outward expansion plate 34 away from the first side support plate 33. The distance between the two second side support plates 35 is greater than the distance between the two first side support plates 33. The front half of the upper hopper 30 is tilted and expanded outward through an outward expansion plate 34, so that the distance between the two second side support plates 35 is greater than the distance between the two first side support plates 33, so that the garbage truck can enter the upper hopper 30 more deeply and cooperate with the upper hopper 30 better. Due to the setting of the adaptive transformation backplate assembly, even if the garbage transfer truck enters a certain distance, it is not easy for garbage to overflow.

[0049] In order to facilitate the garbage transfer vehicle to dock with the upper hopper 30, a guide slope 321 is provided on the side of the lower base plate 32 facing the garbage transfer vehicle, and a plurality of ribs 322 are welded on the top of the lower base plate 32, so that the garbage transfer vehicle can get closer to the upper hopper 30 through the guide slope 321. At the same time, the ribs 322 can increase the strength of the entire lower base plate 32, thereby preventing the upper hopper 30 from being deformed after the garbage transfer vehicle approaches the upper hopper 30.

[0050] In fact, the setting mode of the inductor 511 can be various, for example, it can be infrared induction or pressure induction, therefore, in the embodiment, the specific limitation is not made, and only the structure is described in detail. Specifically, the inner side of the inductor 511 is provided with a first induction sheet 5111 and a second induction sheet 5112, the first induction sheet 5111 is located at the middle position of the second induction sheet 5112 and the rotating shaft 41, when the side baffle 42 does not contact the first induction sheet 5111 and the second induction sheet 5112, the mechanism is in the first working condition, when the side baffle 42 contacts the first induction sheet 5111 and the second induction sheet 5112 at the same time, the mechanism is in the second working condition, when the side baffle 42 only contacts the first induction sheet 5111, the swing piece 52 is started. In the initial stage of the inductor 511, the first induction sheet 5111 and the second induction sheet 5112 in the inductor 511 do not have any contact with the side baffle 42, and after the side baffle 42 rotates, the first induction sheet 5111 and the second induction sheet 5112 are contacted, and if the side baffle 42 is not reset to the position, only the first induction sheet 5111 generates a signal, when the first induction sheet 5111 generates a signal, it indicates that the whole self-adaptive transformation back plate assembly is in the middle position, and is not reset to the position, therefore, the swing piece 52 is self-started in the case that only the first induction sheet 5111 is triggered, drives the whole side baffle 42 to move to the position where the first induction sheet 5111 cannot be triggered, so that the whole self-adaptive transformation back plate assembly can be reset to the position, and still has a large range of receiving space for the next feeding.

[0051] In the embodiment, the setting mode of the swing piece 52 can also be multiple, but since the position of the side baffle 42 is in a changing state, a fixed structure cannot be set, therefore, the swing piece 52 of the embodiment comprises a first hinged seat 521 locked on the feeding hopper 30, the outer side of the side baffle 42 is locked with a second hinged seat 522, the first hinged seat 521 and the second hinged seat 522 are both provided with an ear seat, a draw structure 523 is movably installed on the two ear seats, the side baffle 42 is pulled back through the electric draw structure 523, preferably, the draw structure 523 is a push rod motor, the fixed end and the output end of the push rod motor are connected with the first hinged seat 521 and the second hinged seat 522 respectively, and in other embodiments, the draw structure 523 can also be other structures with a pushing and retracting action.

[0052] In another embodiment of the present application, a cylinder that can automatically limit the stroke can also be directly provided without the inductor 511. When the cylinder is subjected to pressure, it will be compressed. During the overturning process of the feeding hopper 30, the cylinder will be compressed due to the self-adaptive transformation backplate assembly being pressed in. During the resetting process of the feeding hopper 30, the cylinder will be stretched out again to automatically reset the self-adaptive transformation backplate assembly. Preferably, the stretching stroke of the cylinder when the feeding hopper 30 is placed on the floor can be set as the limit pushing stroke. After the feeding hopper 30 is reset to the floor, the cylinder will automatically reset the self-adaptive transformation backplate assembly to the position, without the intervention of the inductor 511, so that the whole structure is more simplified, and meanwhile, it can also avoid that some garbage with large texture or density causes the self-adaptive transformation backplate assembly to be overturned all the time, exceeding the limit position or being damaged.

[0053] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. 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.
