Description

Technical Field

[0001] The invention relates to a garbage collecting device, in particular to an underground classified garbage collecting device and a sliding cover opening mechanism thereof. Background Art

[0002] Garbage classification is a reform of the traditional way of garbage collection and disposal, and a scientific management method for effective garbage disposal. Faced with the increasing garbage production and deteriorating environmental conditions, how to maximize the utilization of garbage resources, reduce the amount of garbage disposal, and improve the living environment through garbage classification management is an urgent issue of common concern to all countries in the world.

[0003] In my country, garbage classification is generally divided into kitchen waste, recyclable waste, hazardous waste and other waste. In order to do a good job of garbage classification, classified garbage bins (garbage collection devices) are essential garbage classification equipment. At present, there are many types of classified garbage bins, but from the perspective of mobility, they can be divided into movable garbage bins and fixed garbage bins. Fixed garbage bins can also be divided into underground garbage bins and room-based garbage bins. Regardless of the type and form of garbage bins, there are problems with whether they are convenient and hygienic to use.

[0004] The underground classified garbage collection device (underground classified garbage bin) is a garbage classification device that buries the main body of the garbage collection device underground and exposes the cover on the ground. This device usually consists of an outer barrel, four classified inner barrels and a cover. The outer barrel is buried underground, and there are four seats in the outer barrel. The four classified inner barrels are correspondingly seated on the four seats, and the cover covers the open part of the upper part of the outer barrel. When citizens throw garbage, they can throw it through the input port on the cover, or open the cover to throw garbage. When it is necessary to remove the garbage in the inner barrel, the sanitation worker opens the cover and lifts the inner barrels one by one through a mechanical device to remove the garbage from the outer barrel, then restores the inner barrel and finally closes the cover.

[0005] The underground classified garbage collection device usually has a large capacity for storing garbage and is heavy. It usually requires the help of a mechanism to lift the inner barrel, and the cover needs to be opened before lifting. Since the cover is large and heavy, how to open the cover directly affects the convenience of the entire device. According to the existing conventional design, if the cover is designed as an open-cover structure, it will be very inconvenient to use and operate due to its large size, heavy weight, and high positioning requirements; if the cover is designed as a flip-cover structure, it will be difficult to operate due to its poor stability and complex structure (generally equipped with air springs as damping). On November 9, 2016, Chinese patent CN106081413A disclosed an invention patent application entitled "A buried garbage can lid and a buried garbage can composed of it". The application discloses a double-open cover consisting of a first cover and a second cover connected by a rotating shaft. Although this cover design is suitable as a cover for underground classified garbage collection devices with large volume and heavy weight, it has the following disadvantages: 1. Since the double-opening cover is limited by the rotation radius, the site requires a large area; 2. The double-opening cover itself has a large area and is prone to deformation, so the elasticity requirements are high and more materials are used; 3. Since the double-opening cover is supported by universal wheels and rotates around the rotation axis, the flatness of the ground is required to be high.

[0006] In view of this, how to design a cover suitable for use in an underground classified garbage collection device is a research topic of the present invention. Summary of the invention

Specific Embodiments

[0056] The present invention will be further described below in conjunction with the drawings and embodiments:

[0057] Embodiment 1: An underground four-class garbage collection device

[0058] As Figure 1-24 shown, the underground four-class garbage collection device is composed of an outer barrel 5, four inner barrels 4 and two cover bodies 1 (see Figure 1-Figure 4 ). Among them, the barrel body of the outer barrel 5 is a cube structure, the top of the outer barrel 5 is open, and four identical seats are provided inside the outer barrel 5, and these four seats are distributed in a "field" shape inside the outer barrel 5. The four inner barrels 4 have the same structure and size, and each inner barrel 4 is placed on one seat of the outer barrel 5 (see Figure 3and Figure 4 ). The inner barrel 4 is provided with four lifting rings 8, which are used by sanitation workers to lift the inner barrel 4 through a mechanical device when unloading garbage. The four inner barrels 4 are arranged in two rows in the outer barrel 5, each row consists of two inner barrels 4, and each row of inner barrels 4 shares a cover 1 (see Figure 1 The top of the cover body 1 is provided with a loading port 10 (see Figure 2 ), each delivery port 10 corresponds to an inner barrel 4, and a garbage classification mark 11 is provided next to the delivery port 10 (see Figure 2 and Figure 4 ), for the user to observe and identify the appropriate delivery port 10 for the four types of garbage. In order to facilitate the opening operation, a handle 12 is also provided on the cover body 1 (see Figure 2 and Figure 4 ).

[0059] The innovation of the present invention is that a sliding cover opening mechanism is specially designed for the underground classified garbage collection device, and the specific contents are as follows:

[0060] Between the cover body 1 and a row of inner barrels 4, a track is arranged on one, and a group of rollers are arranged on the other corresponding to the track, and the arrangement direction of the row of inner barrels 4 is set as the sliding direction of the cover body 1, and the track is arranged in the sliding direction. In the assembled state, the cover body 1 and the row of inner barrels 4 cooperate with the track and the corresponding rollers to form a sliding cover opening mechanism.

[0061] In this embodiment, the track is arranged on the inner barrel 4, and the roller is arranged on the cover 1. The specific implementation method is to configure a section of the guide rail 2 on both sides of the top of each inner barrel 4 (see Figure 4 ), the guide rail 2 is actually composed of angle steel 13 (see Figure 5-Figure 8 ), the angle steel 13 is fixed on both sides of the top of the inner barrel 4 through the guide rail beam 14 and the guide rail bottom plate 15 (see Fig.18 and Fig. 20 ), wherein the right-angled inner side surface of the angle steel 13 is fixedly connected to the top of the guide rail beam 14, the bottom of the guide rail beam 14 is fixedly connected to the guide rail bottom plate 15, and the guide rail bottom plate 15 is fixed to the top sides of the inner barrel 4 by ground bolts or screws (see Fig.18 and Fig. 20 The bottom of the cover 1 is provided with guide wheels 3 corresponding to the two tracks on a row of inner barrels 4 (see Fig.23 and Fig.24 Considering that the cover 1 does not hinder the lifting of an inner barrel 4 when sliding open, theoretically, at least four guide wheels 3 need to be configured on one side of the cover 1 corresponding to the guide rail 2. The guide wheel 3 has a V-shaped groove on its rim. When in use, the V-shaped groove rolls with the right-angled outer side of the angle steel 13 (see Fig.18 and Fig. 20 ).

[0062] In order to solve the problem of track and roller splicing and alignment between the cover body 1 and a row of inner barrels 4, especially the problem of how to accurately splice and align the guide rails 2 on two adjacent inner barrels 4 in a row after lifting to unload garbage and resetting, the present invention is provided with a track positioning structure between each inner barrel 4 and the outer barrel 5, taking the sliding axis of the track set on the row of inner barrels 4 as a reference, setting the sliding axis to the horizontal left and right direction, and the track positioning structure includes a first positioning surface, a second positioning surface, a third positioning surface and a fourth positioning surface, wherein: the first positioning surface is the top surface of the positioning block 16, and the positioning block 16 is fixed relative to the outer barrel 5 (see Figure 6 and Figure 7 ), the bottom surface of the second positioning surface angle steel 13, the angle steel 13 is fixed relative to the inner barrel 4, when the inner barrel 4 is placed in the outer barrel 5, the top surface of the positioning block 16 cooperates with the bottom surface of the angle steel 13 to limit the position of the sliding axis in the vertical up and down direction (see Figure 6 and Figure 7 The third positioning surface is the side surface of the positioning pin 6, and the positioning pin 6 is fixed relative to the inner barrel 4 (see Figure 5 and Figure 8 ), the fourth positioning surface is the side surface of the positioning hole 7, and the positioning hole 7 is fixed relative to the outer barrel 5 (see Figure 6 and Figure 7 ), when the inner barrel 4 is placed in the outer barrel 5, the positioning pin 6 and the positioning hole 7 cooperate to limit the position of the sliding axis in the horizontal front-to-back direction and the horizontal left-to-right direction, so as to realize the connection and alignment of the track and the roller of the same cover body 1 and a row of inner barrels 4 before and after the inner barrel 4 is lifted.

[0063] Figure 6 and Figure 7 The state where the positioning pin 6 is inserted into the positioning hole 7 is shown, so only the positioning hole 7 can be seen but the positioning pin 6 cannot be seen. Figure 5 and Figure 8 The positioning pin 6 shown in the figure is not matched with the positioning hole 7 and is in a suspended state. Because in this embodiment, the track positioning structure is only provided at the joint of the guide rails 2 on two adjacent inner barrels 4 ( Figure 6 and Figure 7 ), and the other end of the corresponding guide rail 2 is a non-joined end. Although the non-joined end is also provided with a positioning pin 6, there is no positioning hole 7 on the outer barrel 5 corresponding to the position of the positioning pin 6, so the positioning pin at this position is in a suspended state (see Figure 5 and Figure 8 ).

[0064] The use process of the buried four-classification garbage collection device of this embodiment is as follows: Figure 1A three-dimensional diagram showing an embodiment of the present invention in use, from which it can be seen that the outer barrel 5 is buried in the foundation 9, and four inner barrels 4 are placed in the outer barrel 5. The four inner barrels 4 are distributed in the outer barrel 5 in a "field" shape. Two covers 1 are provided on the top of the outer barrel 5, and each cover 1 covers two inner barrels 4 arranged in a row. Each cover 1 is provided with two delivery ports 10 (see Figure 2 ), there is also a garbage classification sign 11 next to the delivery port 10 (see Figure 2 and Figure 4 ), for the user to observe and identify the appropriate delivery port 10 for the four types of garbage. The garbage can be delivered to the corresponding inner bucket 4 through the delivery port 10. When the garbage needs to be unloaded, the sanitation worker first slides open a cover 1 through the handle 12 to expose an inner bucket 4 (see Figure 3 ), then the inner barrel 4 is lifted by the mechanical device through the lifting ring 8, and the inner barrel 4 is moved to the garbage truck, the bottom of the inner barrel 4 is opened to unload the garbage, and then the bottom of the inner barrel 4 is closed and moved back to the original position, and finally placed in the outer barrel 5. In the process of placing the inner barrel 4 into the outer barrel 5, the positioning pin 6 cooperates with the positioning hole 7 to realize the positioning of the track and the roller in the horizontal direction, and the guide rail 2 and the positioning block 16 contact and cooperate to realize the positioning of the track and the roller in the vertical direction, and finally the guide rails 2 between the two adjacent inner barrels 4 are accurately spliced ​​and aligned, so that the original state of the sliding cover opening mechanism is quickly and accurately restored.

[0065] Example 2: An underground four-classification garbage collection device

[0066] The difference between the buried four-classification garbage collection device and the embodiment 1 is that the track positioning structure provided between the inner barrel 4 and the outer barrel 5 is different. The track positioning structure in the embodiment 2 takes the sliding axis of the track provided on a row of inner barrels 4 as the reference, and sets the sliding axis to the horizontal left and right direction. The track positioning structure is actually composed of an inner cone and an outer cone. The inner cone can directly use the inner right-angle surface of the angle steel 13 (the outer right-angle surface has been used as the guide surface), and then an additional section of angle steel (not shown) is added, and the outer right-angle surface of the added angle steel is used as the outer cone. In this way, the inner cone is fixed relative to the inner barrel 4, and the outer cone is fixed relative to the outer barrel 5, wherein: the first positioning surface is one side of the inner cone, the second positioning surface is one side of the outer cone, the third positioning surface is another side of the inner cone, and the fourth positioning surface is another side of the outer cone. When the inner barrel 4 is placed in the outer barrel 5, the inner cone cooperates with the outer cone to limit the position of the sliding axis in the vertical up and down direction and the horizontal front and back direction.

[0067] The other contents are the same as those in Example 1 and will not be described again here.

[0068] With respect to the above-mentioned embodiment, possible changes of the present invention are described as follows:

[0069] 1. The above embodiment is an underground four-classification garbage collection device, including an outer barrel 5 and four inner barrels 4. However, the present invention is not limited thereto, and one outer barrel 5 can be configured with two inner barrels 4, three inner barrels 4, five inner barrels 4, or even more. Among them, one outer barrel 5 and four inner barrels 4 are typical of the current four-classification garbage collection devices. This is easy to understand and accept by those skilled in the art.

[0070] 2. In the above embodiment, each row of inner barrels 4 is provided with a cover 1, and two rows of inner barrels 4 are provided with two covers 1 (see Figure 1 ). However, the present invention is not limited thereto, and one cover body 1 may be provided for two rows of inner barrels 4, that is, the two covers 1 in the present embodiment may be replaced with one cover body 1, and the track and the roller are arranged between the cover body 1 and two or more rows of inner barrels 4, and are located on at least two sides of the sliding direction of the cover body 1. Such a change is easily understood and accepted by those skilled in the art.

[0071] 3. In the above embodiment, the track is arranged on a row of inner barrels 4, and a group of rollers is arranged on the cover body 1. However, the present invention is not limited thereto, and the arrangement positions of the track and the rollers can be exchanged, that is, the track is arranged on the cover body 1, and a group of rollers is arranged on a row of inner barrels 4. Such a change can also achieve the same technical effect of the present invention, which can be understood and accepted by those skilled in the art.

[0072] 4. In the above embodiment, the positioning pin 6 is provided on the inner barrel 4, and the positioning hole 7 is provided on the outer barrel 5. However, the present invention is not limited thereto, and the positions of the two can be exchanged, that is, the positioning hole 7 is provided on the inner barrel 4, and the positioning pin 6 is provided on the outer barrel 5. Such a change can also achieve the same technical effect of the present invention, which can be understood and accepted by those skilled in the art.

[0073] 5. In the above embodiments, the sliding cover opening mechanism is a manual operating mechanism. However, the present invention is not limited thereto, and an electric operating mechanism can be formed by adding a motor and a linear drive mechanism. This is understandable and acceptable to those skilled in the art.

[0074] 6. In the above embodiment 1, the positioning pin 6 cooperates with the positioning hole 7 to realize the positioning of the track and the roller in the horizontal direction, and the guide rail 2 cooperates with the positioning block 16 to realize the positioning of the track and the roller in the vertical direction. However, the present invention is not limited to this, and the positioning of the track and the roller in the vertical direction can be realized by the matching relationship of other positions of the inner barrel 4 and the outer barrel 5, such as the limit of the upper edge of the inner barrel 4 and the top end surface of the outer barrel 5. This is understandable and acceptable to those skilled in the art.

[0075] 7. In the above embodiment 2, the track positioning structure is actually composed of angle steels and angle steels. However, the present invention is not limited to this. From the essence of the track positioning structure of embodiment 2, the track positioning structure is composed of an inner cone and an outer cone, wherein: the first positioning surface is a side surface of the inner cone, the second positioning surface is a side surface of the outer cone, the third positioning surface is another side surface of the inner cone, and the fourth positioning surface is another side surface of the outer cone. When the inner barrel 4 is placed in the outer barrel 5, the inner cone and the outer cone are used to limit the position of the sliding axis in the vertical up and down direction and the horizontal front and back direction. All track positioning that meets the requirements of using an inner cone and an outer cone to achieve the desired positioning should be considered as a variation of the track positioning structure in embodiment 2 of the present invention.

[0076] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
