Description

Technical Field

[0001] The present invention relates to the technical field of garbage transportation, and in particular to a garbage transfer device and a transfer method. Background Art

[0002] Garbage is discarded items that have lost their use value, including solid waste and liquid waste.

[0003] In production and life, garbage trucks are usually used to transport solid waste from garbage stations to other locations for landfill or recycling. The rear end of the container of the garbage truck is equipped with a feed door, which can be used to put garbage into the container cavity or dump the garbage in the container cavity (for example, by lifting the front end of the container).

[0004] The Chinese invention patent "Garbage Transfer Device and Garbage Compression Method" (authorization announcement number: CN 110510305 B) discloses a technical solution for placing garbage into a container in the form of lateral propulsion. This solution applies lateral propulsion to the garbage through a reciprocating pusher drive device. However, hard obstacles (such as sand, gravel, metal debris, etc.) are inevitable in the garbage material flow. When the hard obstacles are stuck between the pusher drive device and the bottom surface of the compression channel, the wear of the pusher drive device will be accelerated, and even the pusher drive device will be stuck, and the hydraulic cylinder will explode and be damaged.

[0005] Other similar garbage transfer technologies in traditional technologies have similar problems. Hard obstacles in the garbage flow are stuck between the bottom surface of the compression piston and the bottom surface of the push chamber, causing the compression piston to wear faster or get stuck. At this time, workers are required to stop working, move the garbage truck and clean the hard obstacles from the front end of the push chamber. Cleaning is difficult (for example, the compression piston needs to be removed), which also causes production operations to stagnate and reduces work efficiency. Summary of the invention

[0006] In order to overcome the problem existing in the above background technology that "hard obstacles are stuck between the bottom surface of the compression piston and the bottom surface of the pushing chamber, causing the propulsion component to wear faster or get stuck", the present invention provides a garbage transfer device and a transfer method.

[0009] As a further optimization solution of the present invention, one end of the movable plate away from the fixed plate is hinged to the bottom end of the first linear drive, and the top end of the first linear drive is hinged to the side plate body.

[0010] As a further optimization solution of the present invention, the propulsion assembly also includes a limiting guide rail, which is laterally fixedly installed on the side wall of the pushing chamber, and the bottom surface of the limiting guide rail is slidably connected to the top surface of the compression piston.

[0011] As a further optimization scheme of the present invention, a support groove is provided on the side wall of the limiting guide rail, a partition plate is inserted in the support groove, and the front end of the partition plate is placed directly below the delivery cavity; a reinforcing plate is provided on the lower surface of the partition plate for sealing the gap between the bottom surface of the partition plate and the top surface of the compression piston.

[0012] As a further optimized solution of the present invention, the biting assembly includes a rotatable biting jaw arranged below the end of the main housing, and the biting jaw is connected to the side wall of the main housing through a downward extension mounting plate; a first hinged ring is fixedly installed on the outer side wall of the biting jaw through a first extension plate; a second hinged ring is fixedly installed in the middle of the side wall of the main housing through a second extension plate, and the first hinged ring and the second hinged ring are connected through a second linear actuator.

[0013] As a further optimized solution of the present invention, the downward extension mounting plate is provided with an abutting edge for fitting and abutting against the positioning rod, and a让位间隙 is provided between the first hinged ring and the biting jaw for accommodating the abutting edge.

[0014] As a further optimized solution of the present invention, the biting assembly further includes a clamping angle iron fixedly arranged at the upper end of the end of the main housing, and the clamping angle iron is adapted to the positioning rod.

[0015] As a further optimized solution of the present invention, the biting jaw is in a C shape, and the biting jaw includes a biting rod and side connecting plates fixedly connected to each other. There are two side connecting plates and they are respectively arranged at both ends of the biting rod; a biting groove adapted to the positioning rod is provided at the top of the biting rod; the first extension plate is fixedly connected to the outer side wall of the side connecting plate; the first extension plate is a plate-shaped structure in an L shape, and a triangular reinforcing rib plate is fixedly installed at the inner corner position of the first extension plate. The reinforcing rib plate is provided with an inclined guiding edge, and the guiding edge is adapted to the mounting seat of the positioning rod.

[0016] A garbage transfer method uses a garbage transfer device to transfer and compress garbage. The steps include: S1. Make the biting assembly clamp the positioning rod on the container of the garbage truck. At this time, the feeding门洞 of the container is aligned with and communicates with the pushing cavity; S2. Put garbage into the feeding cavity; S3. The piston-type hydraulic cylinder drives the compression piston to reciprocate horizontally in the pushing cavity, and pushes the garbage falling into the pushing cavity into the container; the front end of the compression piston can extend out of the pushing cavity and into the container to over-push / over-compress the garbage in the container, so as to reduce the amount of garbage rebounding into the pushing cavity; when there is a situation where hard obstacles accumulate between the bottom plate body and the bottom surface of the pushing cavity, the movable plate rotates upward, and then the nozzle sprays a flushing liquid into the water inlet gap, and the flushing liquid carrying the hard obstacles flows out through the drainage groove. During step S3, while the nozzle sprays the flushing liquid into the water inlet gap, the compression piston maintains a horizontal moving state.

[0017] In summary, the beneficial effects of the present invention are as follows:

[0018] (1) The movable plate at the bottom of the compression piston in the garbage transfer device can be flipped upward to release the clamping connection between the hard obstacle, the bottom surface of the compression piston and the bottom surface of the push chamber; the nozzle sprays flushing liquid to the bottom surface of the push chamber through the water inlet gap between the fixed plate and the movable plate, thereby removing the hard obstacle and avoiding the problem of accelerated wear or even jamming of the bottom surface of the compression piston and the main shell.

[0019] (2) The flushing liquid carrying hard obstacles is discharged through the tail of the garbage transfer device. Compared with the front-end cleaning in traditional technology, it can avoid the disengagement of the garbage transfer device and the container, and omit the alignment and loading and unloading steps between the interlocking components and the container, thereby having higher convenience, saving labor hours and improving work efficiency.

[0020] (3) One end of the movable plate away from the fixed plate is tilted upward to form a drainage groove with a sealed top surface. The movable plate can block the flushing liquid splashing from the drainage groove to the telescopic shaft of the connecting column group / cross brace plate / piston hydraulic cylinder, thereby avoiding rust and increasing the service life of the garbage transfer device.

[0021] (4) When the front end of the compression piston extends from the pushing cavity to over-push / over-compress the garbage in the container, the presence of the fixed plate can prevent an excessively large gap from being formed between the lower end of the front plate body and the lower edge of the front end of the main shell body, thereby reducing the flow of the flushing liquid diverted into the container and avoiding the flushing liquid occupying the inner cavity of the container, resulting in a reduction in the garbage holding capacity of the container.

[0022] (5) The first linear drive can drive the movable plate to rotate until the adjacent end surfaces of the movable plate and the fixed plate are pressed against each other, thereby preventing the leachate generated by the compression piston squeezing the garbage from splashing onto the nozzle and causing the nozzle to rust / scale accumulation and the injection direction to deviate, thereby improving the working reliability of the garbage transfer device.

[0023] (6) Two piston hydraulic cylinders are arranged crosswise in an X shape, which can reduce the length of the propulsion assembly, further making the garbage transfer device have a smaller length and space, and improving the convenience of storage and transportation.

[0024] (7) The garbage transfer device has a high degree of automation, which can reduce the need for human intervention and thus achieve higher operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Reference Figure 2-3The connecting column group 122 includes a first connecting column 1221 and a second connecting column 1222, which are both vertically arranged and fixedly installed in the installation cavity; the first connecting column 1221 and the second connecting column 1222 are arranged parallel to each other; the connecting plate group 124 includes a first connecting plate 1241, a second connecting plate 1242 and a third connecting plate 1243 which are arranged parallel to each other, the two ends of the first connecting plate 1241 are respectively fixedly connected to the inner wall of the main housing 1 (for example, by welding or bolts), the two ends of the second connecting plate 1242 are respectively fixedly connected to the inner wall of the main housing 1 (for example, by welding or bolts), and the two ends of the third connecting plate 1243 are respectively fixedly connected to the inner wall of the main housing 1 (for example, by welding or bolts).

The mounting end of the piston hydraulic cylinder 123 is a vertical cylindrical shape; the upper and lower ends of the mounting end of one piston hydraulic cylinder 123 are respectively inserted into the mounting hole of the first connecting plate 1241 and the mounting hole of the second connecting plate 1242 to achieve hinged connection, and the upper and lower ends of the mounting end of the other piston hydraulic cylinder 123 are respectively inserted into the mounting hole of the second connecting plate 1242 and the mounting hole of the third connecting plate 1243 to achieve hinged connection, so as to achieve cross-mounting of the two piston hydraulic cylinders 123; the first connecting column 1221 and the second connecting column 1222 are respectively inserted into the plug-in holes of the telescopic shafts of the two piston hydraulic cylinders 123 to achieve hinged connection. The two piston hydraulic cylinders 123 extend or shorten synchronously, thereby pushing the compression piston 121 to reciprocate and move horizontally. The piston hydraulic cylinder 123 is connected and communicated with the external oil pump through the oil pipe, and the external oil pump is connected and communicated with the external oil tank.

[0051] Reference Figure 1 A snap-fit ​​assembly 13 for engaging the positioning rod of the container 3 is provided at the front end of the main shell 1; it is used to achieve relative fixation of the garbage transfer device, avoid the container 3 and the garbage transfer device from being separated from each other during the garbage transfer process, and ensure functional reliability.

[0052] Reference Figure 4-5, the compression piston 121 has a prismatic shell-like structure, and the cross-section of the compression piston 121 is adapted to the cross-section of the material pushing cavity 11. The compression piston 121 includes side plate bodies 1211, a bottom plate body 1212, a front plate body 1213, and a top plate body 1214. There are two side plate bodies 1211, which are respectively vertically and fixedly connected to both sides of the front plate body 1213 (for example, fixedly connected by bolts or integrally). The side plate bodies 1211 and the front plate body 1213 are arranged in a U-shape; the edges of the top plate body 1214 are respectively vertically and fixedly connected to the top end of the top plate body 1214 and the top ends of the side plate bodies 1211 (for example, fixedly connected by bolts or integrally). The bottom plate body 1212 includes a fixed plate 12121 and a movable plate 12122. The front end of the fixed plate 12121 is fixedly connected to the front plate body 1213 (for example, integrally) and both sides are respectively fixedly connected to the side plate bodies 1211 (for example, integrally). The movable plate 12122 is rotatably connected to the side plate body 1211, and the rotation center is located obliquely above the connection position of the fixed plate 12121 and the movable plate 12122, so that when the movable plate 12122 rotates upward, a water inlet gap 12123 can be formed between the fixed plate 12121 and the movable plate 12122.

[0053] Refer to Figure 5 , two vertically arranged extension wing plates 12125 are fixedly installed on the top surface of the movable plate 12122 (for example, fixedly connected by bolts). The extension wing plates 12125 are located at the position on the top surface of the movable plate 12122 close to the fixed plate 12121, and the upper parts of the extension wing plates 12125 are inclined towards the fixed plate 12121; each of the two extension wing plates 12125 is provided with a socket hole at its top, and the two socket holes are respectively sleeved on the cross shafts at the inner wall positions of the side plate bodies 1211 to achieve rotational connection.

[0054] Refer to Figure 4 And Figure 5A nozzle 1215 is arranged obliquely above the connection position between the fixed plate 12121 and the movable plate 12122. The nozzle 1215 is inverted, and the upper end of the nozzle 1215 is inclined toward the front plate 1213, and the lower end is inclined toward the drainage groove 12124, so that the water spray hole of the nozzle 1215 points to the water inlet gap 12123; the nozzle 1215 can spray out the flushing liquid, and the liquid column of the flushing liquid is inclined toward the drainage groove 12124 so that the flushing liquid can flow into the drainage groove 12124 as much as possible instead of flowing into the gap between the fixed plate 12121 and the bottom surface of the pushing cavity 11, thereby reducing the flow of the flushing liquid diverted into the container 3, and avoiding the flushing liquid occupying the inner cavity of the container 3, resulting in a reduction in the garbage holding capacity of the container 3. When the movable plate 12122 rotates upward, a drainage groove 12124 is formed between the bottom surface of the movable plate 12122 and the bottom surface of the pushing chamber 11, and the movable plate 12122 can block the flushing liquid splashing from the drainage groove 12124 to the telescopic shaft of the piston hydraulic cylinder 123, thereby avoiding rust of the piston hydraulic cylinder 123 and improving its service life.

[0055] Reference Figure 6 The tail of the main shell 1 is tilted downward with the horizontal plane as the reference, and the tilt angle is 3 to 10 degrees, so that the flushing liquid can flow to the tail of the main shell 1. The tail of the main shell 1 is fixedly connected with a sewage riser 16 by bolts. The inner cavity of the sewage riser 16 is connected with the pushing cavity 11, so that the flushing liquid carrying hard obstacles flows into the sewage riser 16 through the drainage groove 12124, and further flows out of the garbage transfer device. A sewage collection bucket or a wastewater sewer is set at the bottom of the sewage riser 16. A rear cover plate 17 for blocking the pushing cavity 11 is provided at the tail of the main shell 1. The rear cover plate 17 is detachably connected to the main shell 1 by bolts; the rear cover plate 17 is provided with a threading hole 171.

[0056] Reference Figure 6 The fixing plate 12121 is used to prevent an excessively large gap from being formed between the lower end of the front plate body 1213 and the lower edge of the front end of the main shell body 1 when the front end of the compression piston 121 extends out of the pushing cavity 11 (over-advancement / over-compression), thereby reducing the flow of the flushing liquid diverted into the container 3 and preventing the flushing liquid from occupying the inner cavity of the container 3, resulting in a reduction in the garbage holding capacity of the container 3.

[0057] Reference Figure 6 The end of the movable plate 12122 away from the fixed plate 12121 is hinged to the bottom end of the first linear actuator, and the top end of the first linear actuator is hinged to the side plate 1211 or the top plate 1214. Two first linear actuators are provided and are respectively arranged on both sides of the piston hydraulic cylinder 123 to ensure the force balance of the movable plate 12122 and avoid structural conflict with the piston hydraulic cylinder 123.

The side wall of the limiting guide rail 125 is provided with a horizontal support groove, and a partition plate 126 is inserted in the support groove, and the two side edges of the partition plate 126 are respectively inserted in the two support grooves. The front end of the partition plate 126 is placed in the pushing cavity 11 directly below the delivery cavity 21, so as to prevent the garbage put into the delivery cavity 21 from directly hitting the compression piston 121, thereby improving the service life of the compression piston 121. A reinforcing plate 1261 is provided on the lower surface of the partition plate 126 to block the gap between the bottom surface of the partition plate 126 and the top surface of the compression piston 121, and the partition plate 126 and the reinforcing plate 1261 are fixedly connected by bolts or by an integrated fixed connection. The reinforcing plate 1261 is used to increase the impact resistance of the partition plate 126 and prevent garbage from entering the rear side of the compression piston 121 through the gap between the partition plate 126 and the compression piston 121 .

The first hinge ring 134 and the second hinge ring 136 are connected through a second linear drive. One end of the second linear drive is hinged to the first hinge ring 134 and the other end is hinged to the second hinge ring 136. When the second linear drive is extended or retracted, it can drive the bite jaw 132 to rotate to achieve bite and release actions.

[0060] Reference Fig. 9 , Fig.10 and Fig.12The lower extension mounting plate 131 is provided with an abutting edge 1311 for adapting to the abutting positioning rod, and a clearance gap 1341 for accommodating the abutting edge 1311 is provided between the first hinge ring 134 and the bite jaw 132. The clearance gap 1341 is provided to make the installation position of the first hinge ring 134 as far outward as possible, so that the first hinge ring 134 is located below the second hinge ring 136, and the distance between the first hinge ring 134 and the lower extension mounting plate 131 is equal to the distance between the second hinge ring 136 and the lower extension mounting plate 131, so as to facilitate the installation of the second linear drive and prevent the second linear drive from being subjected to bending moment; at the same time, the first hinge ring 134 and the lower extension mounting plate 131 are staggered through the clearance gap 1341, which can reduce the length of the bite assembly 13, thereby reducing the overall length of the garbage transfer device and improving the convenience of storage and transportation.

[0071] Reference Figure 1 The side wall of the delivery tube 2 is provided with a side door body 22 that can be opened and closed. After the user opens the side door body 22, he can use a rod-shaped tool to clear the garbage material flow that is stuck in the delivery cavity 21.

[0072] Reference Figure 4 , Figure 5 and Figure 6 , the cross brace 1223 can apply abutment limit force to the movable plate 12122. A tension sensor is provided in the first linear actuator, and the first linear actuator drives the movable plate 12122 to rotate upward. When the tension sensor detects a sudden increase in tension, it is determined that the cross brace 1223 and the movable plate 12122 are in abutment. At this time, the first linear actuator controls the movable plate 12122 to stop rotating, so as to prevent the movable plate 12122 and the cross brace 1223 from being overloaded and damaged; at the same time, the cross brace 1223 can prevent the movable plate 12122 from overturning, so as to prevent the end of the movable plate 12122 away from the movable plate 12122 from colliding with the piston hydraulic cylinder 123, so as to prevent the piston hydraulic cylinder 123 from being damaged.

[0073] A garbage transfer method, using a garbage transfer device to transfer and compress garbage to achieve garbage loading, the steps comprising:

[0074] S1. The engaging assembly 13 is made to clamp the positioning rod on the container 3 on the garbage removal vehicle. At this time, the feeding door opening 31 of the container 3 is aligned with and connected to the pushing cavity 11.

[0075] S2, throwing garbage into the throwing chamber 21.

[0076] S3, the piston hydraulic cylinder 123 drives the compression piston 121 to move back and forth in the pushing cavity 11, pushing the garbage that falls into the pushing cavity 11 into the container 3; the front end of the compression piston 121 can extend from the pushing cavity 11 and extend into the container 3 to over-push / over-compress the garbage in the container 3, thereby reducing the amount of garbage that rebounds from the container 3 into the pushing cavity 11, avoiding the reduction of the available capacity of the pushing cavity 11 (the rebounded garbage will occupy the capacity of the pushing cavity 11, and under the premise of avoiding garbage overflow, the amount of garbage that can be put into the delivery cavity 21 is reduced), thereby improving work efficiency; if hard obstacles accumulate between the bottom plate body 1212 and the bottom surface of the pushing cavity 11 If the user hears the sound of sand and gravel scratching at the bottom of the compression piston 121 during the return stroke of the compression piston 121, it is determined that hard obstacles have accumulated), the first linear drive drives the movable plate 12122 to rotate upward away from the end of the fixed plate 12121, further opening the water inlet gap 12123, and then the nozzle 1215 sprays flushing liquid into the water inlet gap 12123, and the flushing liquid carrying the hard obstacles flows out through the drainage trough 12124 and the sewage riser 16, thereby removing the hard obstacles, avoiding excessive wear or jamming of the garbage transfer device, increasing the service life of the garbage transfer device, and improving the work efficiency of the garbage loading operation. After the user determines that the hard obstacle has been removed by observing the sewage riser 16 or by the scratching sound, the first linear drive drives the movable plate 12122 to rotate downward away from one end of the fixed plate 12121, so that the bottom surface of the movable plate 12122 and the bottom surface of the fixed plate 12121 are coplanar and synchronously bear the weight of the compression piston 121, thereby avoiding the problem of accelerated wear caused by the single load-bearing of the fixed plate 12121.

[0077] During step S3, the nozzle 1215 sprays the flushing liquid into the water inlet gap 12123 while the compression piston 121 keeps reciprocating and lateral movement. The nozzle 1215 is in a reciprocating and lateral movement state, thereby increasing the speed at which the hard obstacles are discharged along the bottom plate of the pushing chamber 11. The computer controls the nozzle 1215 to spray the cleaning liquid only when the compression piston 121 returns (i.e., moves toward the rear of the main housing 1), thereby preventing the hard obstacles from moving forward.

[0078] During step S3, when one end of the movable plate 12122 away from the fixed plate 12121 is in an upward state, it is inevitable that a small amount of cleaning liquid can be diverted and flow into the bottom of the fixed plate 12121, thereby lubricating the lower surface of the fixed plate 12121, so as to reduce the wear rate of the fixed plate 12121 and avoid the problem of jamming caused by the sudden increase in pressure between the fixed plate 12121 and the pushing chamber 11.

[0079] The present invention has a simple structure and reliable functions. The compression piston 121 located in the pushing cavity 11 and capable of reciprocating and transversely moving along the length direction of the pushing cavity 11 can push the garbage falling into the pushing cavity 11 into the container 3 and compact it, thereby realizing the horizontal input of the garbage and adapting to the opening position of the feed door 31 of the container 3.
