Description

TECHNICAL FIELD

[0001] The present application relates to the field of compression garbage cans, in particular to an automatic control method of a compression garbage can. BACKGROUND

[0002] At present, in the domestic garbage disposal equipment, the process of compressing garbage into the collection box by the compression garbage can mainly includes: first, the garbage is poured into the compression bin, and then the garbage is pushed by the push plate in the compression bin through the compression port connected with the collection box and compressed into the collection box.

[0003] The compression port of the existing compression garbage can is generally designed to be slightly higher than the height of the push plate. When the push plate moves to the compression port, the gap above is small, which has the advantages of close cooperation and high efficiency of garbage loading into the box. However, in the case of urban health cleaning or pruning of urban roadside branches, the garbage often contains a small amount of large or long high-density bulk garbage (such as wooden boards, wooden sticks, large stones, and large construction waste), at this time, before the compression port with the push plate is applied to compress the garbage, the bulk garbage needs to be sorted out manually, and then the sorted garbage is poured into the compression bin for compression treatment, which makes the garbage disposal efficiency extremely low and the workload huge.

[0004] If the unsorted or incompletely sorted garbage is directly introduced into the compression bin, the bulk garbage will be pushed into the compression port, and due to the small cooperation gap between the upper end of the push plate and the compression port, it is easy to be stuck in the compression port. The maximum thrust and maximum stroke of the push plate are fixed values, so it is difficult to crush or cut the garbage stuck in the compression port by the push plate and push it into the collection, and only manual removal can make the compression work normal after stopping, which makes the garbage compression processing efficiency low and greatly reduces the work efficiency.

[0028] The beneficial effects of the present application are:

[0029] 1、The present application adds a material blocking mechanism, in the process that the compression oil cylinder drives the pushing piece to reciprocate and compress to push the garbage in the compression channel through the compression port into the collection cavity, when a large piece of garbage is stuck at the compression port by the pushing piece, the driving pressure P of the compression oil cylinder is greater than or equal to the preset pressure P1, the adjusting driving device drives the adjusting plate to rise to the first height to expand the area of the garbage inlet at the upper part of the compression port, so that the pushing piece can retract smoothly, and when the pushing piece continues to extend and compress, the garbage stuck in the compression port can be pushed into the collection cavity through the expanded compression port, thereby when a small amount of large block-shaped or long-shaped high-density large garbage is contained in the garbage due to city sanitation cleaning or trimming of city roadside branches, manual pre-sorting of large garbage is not required, frequent shutdown for processing of large garbage is not required, the labor intensity of workers is reduced, the working time is shortened, and the working efficiency of garbage compression processing is improved; when the driving pressure P is less than the preset pressure P1 after the large garbage is cleaned, the adjusting driving device drives the adjusting plate to descend and reset, so as to restore the area of the compression port, so that the area of the compression port is restored to the size that is closely matched with the pushing piece, the gap between the compression port and the pushing piece is avoided to be too large, the garbage in the collection cavity is prevented from being squeezed out and flowing back to the material inlet cavity in the compression process, and the stability of garbage compression processing is maintained.

[0030] 2、The application drives the further retraction of the telescopic end of the adjusting driving device to drive the main plate and the swing plate to rise again to the upper end of the main plate abutting against the upper end of the long slide groove, the swing plate is separated from the short slide groove into the adjusting area, and then the swing plate is swung to the second height to further expand the area of the compression port, so that the pushing and pressing member can push and press the long strip-shaped garbage such as branches into the collecting cavity through the further expanded compression port and the inclined guide after the swing of the swing plate, and the garbage in the collecting cavity can be pushed backward and the garbage in the feeding cavity can be guided to be squeezed into the compression port after the swing of the swing plate, so as to reduce the probability of the garbage in the collecting cavity flowing back to the feeding cavity when the pushing and pressing member reciprocally compresses, and the effect of cleaning the jammed long strip-shaped garbage while avoiding affecting the compression efficiency is realized.

[0031] 3、The application adds the magnetic attraction part and the electromagnet, when the upper end of the main plate abuts against the upper end of the long slide groove, the electromagnet is opened to attract the magnetic attraction part to assist in fixing the main plate, so that the stability of the swing of the swing plate to the second height by the adjusting driving device is improved, and the stress of the telescopic end of the adjusting driving device is reduced, and the damage probability of the adjusting driving device is reduced; when the swing plate is swung back to the original position, the electromagnet is closed to release the magnetic attraction part, so that the magnetic attraction part is released by the electromagnet after the swing plate is swung back to the original position, the stability of the swing back of the swing plate to the original position by the adjusting driving device is improved, and the stress of the telescopic end of the adjusting driving device is reduced, and the damage probability of the adjusting driving device is reduced.

At the same time, when the garbage compressed by the pushing and pressing member passes through the compression port, the pushing force borne by the main plate and the swing plate can be reduced by the friction of the damping particles in the first reinforcing rib and the second reinforcing rib, the impact resistance of the main plate and the swing plate during compression is improved, and the practicability of the garbage blocking mechanism is improved.

[0033] Although the addition of the first reinforcing rib, the second reinforcing rib and the damping particle can improve the structural strength and impact resistance of the main plate and the swing plate, the overall weight of the main plate and the swing plate is increased. However, the addition of the electromagnet and the magnetic attraction part enables the adjusting driving device to stably drive the main plate and the swing plate with the first reinforcing rib, the second reinforcing rib and the damping particle.

[0042] In the description of the present application, the terms "first", "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0043] Example One

[0044] Referring to Figure 1 The automatic control method of the compression type garbage can shown in the figure comprises:

[0045] The compression type garbage can comprises:

[0046] A box body 1, which internally comprises a compression channel 11, a material inlet cavity 12 communicated above the compression channel 11, and a collection cavity 13 communicated with one end of the compression channel 11 and arranged at the rear side of the material inlet cavity 12;

[0047] A compression mechanism 2, which comprises a compression oil cylinder 21 arranged in the other end of the compression channel 11, a pushing piece 22 driven to slide and compress along the compression channel 11 by the compression oil cylinder 21, and a pressure detection device for detecting the driving pressure P of the pushing piece 22 when the pushing piece 22 is pushed by the compression oil cylinder 21;

[0048] The material blocking mechanism 3 includes a front material blocking plate 31 which is arranged between the feeding chamber 12 and the collecting chamber 13 and has a lower end spaced apart from the top of the compression channel 11, and an adjusting plate 32 which is arranged on the rear side of the front material blocking plate 31 and is driven by an adjusting driving device 33 to move up and down. Specifically, the adjusting plate 32 can be arranged in a corresponding guide frame by sliding up and down on both sides to achieve up and down movement. A gap is set between the lower end of the adjusting plate 32 and the top of the compression channel 11, and a compression port 5 is formed between the lower end of the adjusting plate 32 and one end of the compression channel 11;

[0049] The control method includes:

[0050] S1, while the compression cylinder 21 drives the pushing member 22 to reciprocate and compress the garbage in the compression channel 11 to enter the collection chamber 13 through the compression port 5, a detection signal of the pressure detection device is obtained. Specifically, the compression cylinder 21 can achieve fixed reciprocating compression by means of program control or the like. For details, reference may be made to the prior art and will not be repeated here.

[0051] S2, when the driving pressure P ≥ the preset pressure P1, it is determined that a large piece of garbage is stuck at the compression port 5, and the adjusting driving device 33 drives the adjusting plate 32 to rise to the first height to expand the area of ​​the compression port 5. Specifically, the preset pressure P1 can be adaptively adjusted according to specific circumstances and is not specifically limited here; thereby, the pushing member 22 can be smoothly retracted, and when the pushing member 22 continues to extend and compress, the stuck garbage can be pushed into the collection chamber 13 through the expanded compression port 5. Therefore, when the garbage contains a small amount of large or long, high-density garbage due to urban sanitation cleaning or pruning of urban roadside branches, there is no need to manually sort the large garbage in advance, nor is there any need to frequently stop the machine to process the large garbage, thereby reducing the workload of staff and shortening working time, thereby improving the efficiency of garbage compression processing;

[0052] S3, when the driving pressure P is less than the preset pressure P1, it is determined that the large piece of garbage has been pushed into the collecting chamber 13, and the adjusting driving device 33 drives the adjusting plate 32 to descend and reset to restore the area of ​​the compression port 5, so that the area of ​​the compression port 5 is restored to a size that closely matches the pushing member 22, avoiding the gap between the compression port 5 and the pushing member 22 being too large, which causes the garbage in the collecting chamber 13 to be squeezed out and flowed back into the feeding chamber 12 during the compression process, thereby maintaining the stability of the garbage compression processing.

[0053] In order to prevent the garbage in the collection chamber 13 from interfering with the movement of the telescopic end of the adjusting drive device 33 and affecting the driving stability, the material blocking mechanism 3 also includes a rear material blocking plate 34 fixed to the rear side of the front material blocking plate 31, and the lower end of the rear material blocking plate 34 is set at a distance from the top of the compression port 5.

[0054] In order to improve the safety of the garbage can in use, the compression type garbage can further comprises a voice module and a camera 4 arranged at the top of the inlet cavity 12. When the driving pressure P≥ the preset pressure P1, the voice module gives a voice reminder, and the camera 4 is used to shoot the inside of the inlet cavity 12. Specifically, the voice module can be arranged at the outer wall of the garbage can or the vehicle-mounted console of the garbage truck or the like. Thus, when a large piece of garbage is stuck in the compression port 5, the voice module gives a voice reminder to the staff that there is a large piece of garbage stuck, and the staff can observe the situation of the large piece of garbage stuck through the camera 4. If it is not serious, it can be automatically processed through the control method, and if it is serious, it can be directly stopped for manual processing.

[0055] Specifically, the compression oil cylinder 21 comprises a telescopic rod 211 hinged to the front side of the push piece 22, a first driving cavity and a second driving cavity for driving the telescopic rod 211 to extend and retract, the first driving cavity and the second driving cavity are connected to corresponding oil sources through an extension driving oil way and a retraction driving oil way respectively, the pressure detection device is a pressure switch arranged on the extension driving oil way, the pressure switch adopts a high-precision and high-stability pressure sensor and a transmission circuit, and then a special CPU modular signal processing technology is used to realize the detection, display, alarm and control signal output of the medium pressure signal. When the driving pressure P≥ the preset pressure P1, the pressure switch is closed and sends a signal to the corresponding controller. When the driving pressure P< the preset pressure P1, the pressure switch is opened. Therefore, when the controller receives the signal, it can be judged that the pressure switch is closed and the driving pressure P≥ the preset pressure P1, and then it can be judged that a large piece of garbage is stuck at the compression port 5. When the controller does not receive the signal, it can be judged that the pressure switch is opened and the driving pressure P< the preset pressure P1, and then it can be judged that the large piece of garbage has been pushed into the collection cavity 13.

[0056] Embodiment two

[0057] Referring to Figures 2-8 When the large piece of garbage is a long strip of branch, it is difficult to push it into the collection cavity 13 by the push piece 22 after the adjusting plate 32 rises to the first height. At this time, it is necessary to further expand the area of the compression port 5 to make it pass through, but this will make the gap between the upper end of the push piece 22 and the compression port 5 too large after the push piece 22 is pushed into the compression port 5, resulting in that the garbage in the collection cavity 13 flows back to the inlet cavity 12 after being squeezed, and the compression effect is invalid, and the compression mechanism 2 does useless work. Therefore, the difference between the present embodiment and the first embodiment is that:

[0058] The adjusting plate 32 comprises a main plate 321 and a swing plate 322 arranged in an up-down distribution and hinged at opposite ends, specifically, the rear sides of the main plate 321 and the swing plate 322 are hingedly arranged through a plurality of spars arranged at intervals, the material blocking mechanism 3 further comprises guide columns 35 arranged outside the top of the compression channel 11, the opposite sides of the two guide columns 35 are respectively provided with long grooves 351 and short grooves 352 corresponding to the main plate 321 and the swing plate 322, the upper parts of the opposite sides of the two guide columns 35 are recessed to form an adjusting area 354 with a width matching the width of the swing plate 322, the two sides of the main plate 321 and the swing plate 322 are respectively arranged in the long grooves 351 and the short grooves 352 in an up-down sliding manner, and the fixed end and the telescopic end of the adjusting driving device 33 are respectively hinged to the rear sides of the front material blocking plate 31 and the swing plate 322; specifically, the guide columns 35 can be integrally arranged, can be arranged in a split manner and then welded and assembled, etc., which is not specifically limited here.

[0059] Step S2 specifically comprises: when the driving pressure P is greater than or equal to the preset pressure P1, it is judged that a large piece of garbage is stuck at the compression port 5, the telescopic end of the adjusting driving device 33 is retracted to drive the main plate 321 and the swing plate 322 to rise to a first height and be positioned in the upper part of the short groove 352, after timing T1, specifically, the length of T1 can be adaptively adjusted according to specific conditions, for example, 5S, which is not specifically limited here, if the driving pressure P is greater than or equal to the preset pressure P1, it is judged that a large piece of garbage is still stuck at the compression port 5, the telescopic end of the adjusting driving device 33 is further retracted to drive the main plate 321 and the swing plate 322 to rise again to the upper end of the main plate 321 abutting the upper end of the long groove 351, the swing plate 322 is separated from the short groove 352 into the adjusting area 354, and then the swing plate 322 is swung to a second height to further expand the area of the compression port 5; specifically, when the swing plate 322 swings, a connecting rod mechanism is formed between the main plate 321, the swing plate 322 and the adjusting driving device 33; so that the pushing and pressing piece 22 can push and press the long strip-shaped garbage such as branches to break into the collecting cavity 13 through the further expanded compression port 5 and the inclined guide after the swing of the swing plate 322; and after the swing of the swing plate 322, the garbage in the collecting cavity 13 can be pushed backward, and the garbage in the feeding cavity 12 is guided to be squeezed into the compression port 5, thereby reducing the probability of garbage in the collecting cavity 13 flowing back to the feeding cavity 12 when the pushing and pressing piece 22 reciprocally compresses, and achieving the effect of cleaning the long strip-shaped garbage while avoiding affecting the compression efficiency.

[0060] The step S3 specifically comprises: when the driving pressure P is less than the preset pressure P1, it is judged that the bulk garbage has been pushed into the collecting cavity 13, the telescopic end of the adjusting driving device 33 is extended, the swing plate 322 is first driven to swing forward to reset, and then the swing plate 322 and the main plate 321 are driven to descend to reset, so as to restore the area of the compression port 5.

[0061] The overall specification of the adjusting plate 32 changes with the size of the garbage can, when the garbage can is larger, the specification of the adjusting plate 32 is large, and the self-weight is large, when the swing plate 322 is swung backward by the adjusting driving device 33, the lifting and swinging of the swing plate 322 and the lifting of the main plate 321 are all driven by the telescopic end of the adjusting driving device 33 and the hinge between the swing plate 322, which is easy to cause the driving instability of the adjusting driving device 33, and even the driving failure and the falling of the main plate 321, therefore, in order to improve the stability of the driving of the adjusting driving device 33 and improve the practicability of the compression type garbage can when falling to the ground, the upper end of the main plate 321 is provided with a magnetic attraction part 3211, specifically, the magnetic attraction part 3211 can be made of a material that can be attracted by magnet, such as iron, a fixed rod 311 located between the two guide columns 35 is fixed at the rear side of the front material blocking plate 31, the lower end of the fixed rod 311 is flush with the upper end of the long sliding groove 351, and a plurality of electromagnets 312 for attracting the magnetic attraction part 3211 are arranged in the fixed rod 311.

[0062] The step S2 further comprises: when the upper end of the main plate 321 abuts against the upper end of the long sliding groove 351, the plurality of electromagnets 312 are turned on to attract the magnetic attraction part 3211 to assist in fixing the main plate 321, so that the plurality of electromagnets 312 assist in fixing the main plate 321, improve the stability of the swing plate 322 being swung backward to the second height by the adjusting driving device 33, and at the same time, the stress on the telescopic end of the adjusting driving device 33 is reduced, and the damage probability of the adjusting driving device 33 is reduced.

[0063] The step S3 further comprises: when the swing plate 322 swings forward to reset, the plurality of electromagnets 312 are turned off to release the magnetic attraction part 3211, so that the plurality of electromagnets 312 release the magnetic attraction part 3211 after the swing plate 322 swings forward to reset, the stability of the swing plate 322 being swung forward to reset by the adjusting driving device 33 is improved, and at the same time, the stress on the telescopic end of the adjusting driving device 33 is reduced, and the damage probability of the adjusting driving device 33 is reduced.

[0064] In order to further improve the driving stability of the adjusting driving device 33, the rear part of the two guide columns 35 opposite sides is provided with a limiting sliding groove 353, the limiting sliding groove 353 comprises a lifting area 3531 arranged vertically from bottom to top, and a rear swing area 3532 which is communicated with the lifting area 3531 at the lower end and extends upwardly and rearwardly in an arc shape at the upper end. The adjusting driving device 33 comprises a plurality of adjusting oil cylinders, and the telescopic ends of the plurality of adjusting oil cylinders are transversely connected by a linkage rod 39, and the two ends of the linkage rod 39 are arranged in the limiting sliding groove 353 by roller sliding. Thus, the movement track of the telescopic ends of the adjusting driving device 33 is limited and guided by the cooperation of the limiting sliding groove 353 and the linkage rod 39, so as to improve the driving stability of the adjusting driving device 33.

[0065] Since the pushing member 22 compresses the garbage and causes a large impact on the hinge joint between the main plate 321, the swing plate 322 and the telescopic end of the adjusting driving device 33, the hinge joint is prone to be broken due to excessive force, which causes driving failure, and the main plate 321 and the swing plate 322 fall off. In order to improve the structural strength of the main plate 321 and the swing plate 322 and reduce the stress intensity of the hinge joint, the rear part of the main plate 321 and the swing plate 322 is respectively provided with a plurality of first reinforcing ribs 36 and a plurality of second reinforcing ribs 37 which extend vertically. The plurality of first reinforcing ribs 36 and the plurality of second reinforcing ribs 37 are one-to-one corresponding and oppositely chamfered. When the swing plate 322 swings to the second height, the opposite faces of the one-to-one corresponding first reinforcing ribs 36 and second reinforcing ribs 37 are arranged in abutment. Thus, the structural strength of the main plate 321 and the swing plate 322 is improved by the addition of the plurality of first reinforcing ribs 36 and the plurality of second reinforcing ribs 37. After the swing plate 322 swings, the abutment between the plurality of first reinforcing ribs 36 and the plurality of second reinforcing ribs 37 can reduce the extrusion force of the hinge joint between the telescopic end of the adjusting driving device 33 and the swing plate 322 when the pushing member 22 compresses the garbage, so as to improve the stability of the garbage blocking mechanism 3 as a whole.

[0066] In order to improve the structural strength of the first reinforcing ribs 36 and the second reinforcing ribs 37, the first reinforcing ribs 36 and the second reinforcing ribs 37 are hollow and filled with a plurality of damping particles 38. Specifically, the damping particles 38 can be iron-based spherical particles, aluminum-based spherical particles or the like. The friction between the plurality of damping particles 38 can form obvious damping effect, so that when the pushing member 22 compresses the garbage through the compression port 5, the thrust of the main plate 321 and the swing plate 322 can be reduced by the friction between the damping particles 38 in the first reinforcing ribs 36 and the second reinforcing ribs 37, which improves the impact resistance of the main plate 321 and the swing plate 322 during compression work, and improves the practicability of the garbage blocking mechanism 3.

[0067] The addition of the first reinforcing ribs 36, the second reinforcing ribs 37 and the damping particles 38 can improve the structural strength and impact resistance of the main plate 321 and the swing plate 322, but also increases the overall weight of the main plate 321 and the swing plate 322. However, the addition of the electromagnet 312 and the magnetic attraction part 3211 enables the adjustment driving device 33 to stably drive the main plate 321 and the swing plate 322 with the first reinforcing ribs 36 and the second reinforcing ribs 37 and the damping particles 38.

[0068] To avoid the pressure applied by the garbage in the collection cavity 13 on the swing plate 322 after swinging being too large, the garbage blocking mechanism 3 further comprises a rear garbage blocking plate 34 fixed to the rear side of the front garbage blocking plate 31. The lower end of the rear garbage blocking plate 34 extends rearward and is spaced from the top of the compression opening 5. An active space is formed between the rear garbage blocking plate 34 and the front garbage blocking plate 31. The adjustment plate 32, the adjustment driving device 33 and the guide column 35 are located in the active space. The swing angle of the swing plate 322 is not greater than 60°. Thus, the garbage in the collection cavity 13 is blocked by the rear garbage blocking plate 34, avoiding the driving of the adjustment driving device 33. Preferably, in the embodiment, the swing angle of the swing plate 322 is a set value, for example, 50°. Thus, the swing plate 322 can have a garbage guiding effect while further expanding the compression opening 5.

For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
