Description

Technical Field

[0001] The invention belongs to the technical field of garbage processing equipment, and more specifically relates to a linkage type garbage feeder. Background Art

[0002] Garbage feeders are often installed in fixed garbage transfer stations, one-piece self-compressing garbage bins or garbage transfer vehicles. When installed in fixed garbage transfer stations, they are used to dump the garbage in the garbage bin into the garbage transfer bin in the fixed garbage station. When installed in one-piece self-compressing garbage bins and garbage transfer vehicles, they are used to directly dump the garbage into the corresponding garbage bin. The working principle of the traditional feeder is: first open the cover at the garbage feeding port, and then use its own hanging bucket flipping feeding device to clamp the garbage bin to be dumped, and then use the actuator to raise the garbage bin to a certain height and dump the garbage bin, so as to dump the garbage in the garbage bin into the garbage feeding box. After the garbage is loaded, close the cover of the garbage feeding box, and finally transport the garbage to a unified garbage recycling and treatment site.

[0003] Existing garbage feeders are generally driven by multiple sets of actuators (the actuators can be oil cylinders or air cylinders). For example, the cover of the garbage feeding box is pushed by a set of actuators, and the hanging bucket flip feeding device is driven by one or more sets of actuators. This not only has a complex structure, but also leads to increased subsequent maintenance costs.

[0004] In addition, the existing hanging bucket flip feeding device generally adopts the method of oil cylinder lifting to achieve linkage. This method has a small adjustment range and a long required stroke, which can no longer meet people's use needs.

[0005] Therefore, it is urgent to produce a linkage type garbage feeder with simple structure and low maintenance cost to solve the above problems. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a linkage type garbage feeder, which uses a single cylinder actuator to simultaneously complete the cover opening and feeding operations, which not only has low energy consumption, but also can reduce subsequent maintenance costs.

[0007] To achieve the above object, the present invention provides the following technical solution: a linkage type garbage feeder, comprising:

[0008] A garbage feeding box, wherein the garbage feeding box is provided with a garbage dumping opening;

[0009] The bucket flipping feeding device has an initial position and a discharge position, and is used to clamp the garbage can and feed the garbage into the garbage dumping port, and includes a bucket rack connected to the garbage feeding box through a bucket rack fixing seat, a connecting rod lifting frame hinged to the lower end of the bucket rack fixing seat, and a flip lifting arm arranged on both sides of the bucket rack and used to clamp the garbage can, and the bucket rack is hinged to the upper end of the bucket rack fixing seat;

[0010] A cover plate is used to open and close the garbage dumping port, and both sides of the lower edge of the cover plate are provided with cover plate opening and closing cantilevers, the upper end of the cover plate opening and closing cantilever is connected to one side of the top of the garbage feeding box through a rotating shaft, and the lower end of the cover plate opening and closing cantilever is hinged with a cover plate linkage rod, and the other end of the cover plate linkage rod is hinged to the connecting rod lifting frame;

[0011] The cylinder actuator is hinged on the cylinder fixing seat of the outer wall of the garbage feeding box, and the end of the piston rod is hinged to the connecting rod lifting frame to drive the connecting rod lifting frame to push the barrel hanging frame to flip, and at the same time complete the opening or closing action of the cover plate.

[0012] By adopting the above technical solution, when working, first push the trash can toward the trash hanging rack, then clamp the trash hanging shafts on both sides of the trash can by flipping the lifting arm, after the trash can is clamped stably, start the cylinder actuator, and drive the trash can to flip through the connecting rod lifting frame, and at the same time, the cover is opened through the linkage of the cover linkage rod and the connecting rod lifting frame.

[0013] In summary, the above-mentioned single cylinder actuator is used to simultaneously complete the cover opening and feeding operations, which not only has low energy consumption, but also can reduce the subsequent maintenance costs, and effectively prevents the leakage of garbage odor and reduces the pollution to the surrounding air.

[0014] The present invention is further configured as follows: the barrel hanging rack comprises:

[0015] A bucket frame, the bucket frame is composed of a horizontally arranged hanging tooth fixing seat and two bucket brackets vertically connected to the hanging tooth fixing seat, the hanging tooth fixing seat is connected to the garbage feeding box through a bucket bracket fixing seat, and the flip lifting arm is installed at both ends of the hanging tooth fixing seat;

[0016] A hanging tooth assembly, which is arranged on a side of the hanging tooth fixing seat facing the trash can and is used to hang the trash can;

[0017] A pressing plate mechanism, which is arranged on the hanging tooth fixing seat and is used to press the upper end plane of the garbage bin when the hanging bucket flip feeding device is in the unloading position;

[0018] The trash can support plate is connected to the lower end of the hanging bucket bracket through a support plate fixing seat, and is used to press against the lower end outer wall of the trash can when the hanging bucket turning and feeding device performs a turning action.

[0019] By adopting the above technical solution, the flip lifting arm can be adapted to a large trash can with a bucket hanging shaft, and the hanging tooth assembly can be adapted to a small trash can with a hanging tooth groove. When feeding the small trash can, first push the small trash can to the hanging tooth fixing seat, and hang the small trash can on the hanging tooth assembly, then start the cylinder actuator, and drive the small trash can to flip through the connecting rod lifting frame. During this process, the trash can support plate can be pressed against the lower end outer wall of the small trash can, so as to improve the stability of the small trash can during the flipping process.

[0020] When the small trash can is turned over to the unloading position, the upper surface of the small trash can is pressed by the pressing plate mechanism to prevent the small trash can from falling into the garbage feeding box.

[0021] The present invention is further configured as follows: the hanging tooth assembly is configured as two groups, each group of the hanging tooth assembly is composed of a plurality of hanging tooth racks distributed at equal intervals along the length direction of the hanging tooth fixing seat, and the hanging tooth racks have hanging tooth tips that match the hanging tooth grooves formed on the outer edge of the trash can.

[0022] By adopting the above technical solution, in the specific use process, the hanging tooth tip on the hanging tooth frame can be used to match with conventional small trash cans on the market, such as 120L or 240L small trash cans, so as to meet different usage requirements. In addition, by setting the hanging tooth assembly into two groups, the tipping operation of two small trash cans can be realized at the same time, so as to improve the work efficiency.

[0023] The present invention is further configured as follows: at least one automatic trash can sensing device is provided on the hanging tooth assembly, and the automatic trash can sensing device is electrically connected to the cylinder actuator through a controller.

[0024] By adopting the above technical solution, when the automatic sensing device of the trash can senses that the small trash can is in place, it can automatically trigger the cylinder actuator, so that the cylinder actuator controls the hanging bucket flipping and feeding device to perform the tipping operation. This does not require manual control of the operation button, which is more intelligent.

[0025] The present invention is further configured as follows: the pressure plate mechanism includes an L-shaped pressure plate, a cover plate hinge seat connecting the pressure plate and the hanging tooth fixing seat, and a cover plate return spring connecting the cover plate hinge seat and the hanging bucket bracket, the cover plate hinge seat is rotatably arranged on the side of the hanging tooth fixing seat facing the garbage feeding box, one end of the cover plate return spring is connected to the middle part of the cover plate hinge seat, and the other end is fixed to the side wall of the hanging bucket bracket, which is used to pull the garbage can pressure plate back to the initial position so that the opening angle of the garbage can pressure plate and the hanging tooth assembly is maximum.

[0026] By adopting the above technical solution, when the hanging bucket flipping feeding device is in the initial position, the opening angle of the trash can pressing plate and the hanging tooth assembly can be maximized, thereby avoiding affecting the coordination between the trash can and the hanging tooth frame.

[0027] The present invention is further configured as follows: the connecting rod lifting frame includes two groups of parallel four-bar linkage mechanisms, each group of the parallel four-bar linkage mechanisms includes a first connecting rod connected to a hanging tooth fixing seat at one end through a connecting rod fixing seat, a second connecting rod hinged to the middle of the first connecting rod at one end, a third connecting rod hinged to the other end of the second connecting rod at one end, and a fourth connecting rod hinged to the other end of the first connecting rod at one end and hinged to the middle of the third connecting rod at the other end, the other end of the third connecting rod is connected to a cover plate linkage rod through a connecting sleeve, a linkage support rod is connected between the two third connecting rods, and the piston rod of the cylinder actuator is hinged to the linkage support rod.

[0028] By adopting the above technical solution, after the oil cylinder actuator is started, the two sets of parallel four-bar linkage mechanisms can be controlled to move simultaneously through the linkage support rod, so as to realize the tilting operation of the hanging barrel flip feeding device. Among them, the parallel four-bar linkage mechanism can achieve the effect of achieving a larger adjustment range within a shorter stroke.

[0029] The present invention is further configured as follows: the fourth connecting rod is vertically arranged on the outer wall of the garbage feeding box through a connecting rod mounting seat, and a descent position sensor and a flip position sensor electrically connected to the cylinder actuator are installed on the outer wall; the descent position sensor is located above the flip position sensor, and the descent position sensor is close to the hinge point between the fourth connecting rod and the first connecting rod, and the flip position sensor is close to the hinge point between the fourth connecting rod and the third connecting rod.

[0030] By adopting the above technical solution, when the descent-in-place sensor senses the first connecting rod, it indicates that the hanging bucket flipping and feeding device has been descended into place. At this time, the cylinder actuator is automatically closed, and the next trash can tipping operation can be carried out; when the flipping-in-place sensor senses the third connecting rod, it indicates that the hanging bucket flipping and feeding device has been flipped into place. At this time, the cylinder actuator is automatically closed to prevent the trash can from tilting excessively and falling into the trash feeding box.

[0031] The present invention is further configured as follows: windshields slidingly matched with both sides of the inner wall of the garbage feeding box are arranged on both sides of the cover plate, and when the hanging bucket flip feeding device is in the unloading position, the two windshields are respectively located on both sides of the discharge port of the garbage bin.

[0032] By adopting the above technical solution, when the external wind force is strong, the wind shield can prevent the garbage at the discharge port of the garbage bin from being blown out of the garbage feeding box by the wind.

[0033] The present invention is further configured as follows: protective shells are arranged on both sides of the outer wall of the garbage feeding box, a hidden space is formed between the protective shell and the outer wall of the garbage feeding box, the cover plate linkage rod is located in the hidden space, and a through hole that is connected to the hidden space and for one end of the cover plate linkage rod to pass through is opened on the outer wall of the garbage feeding box.

[0034] By adopting the above technical solution, the cover plate linkage rod is hidden in a concealed space, which not only prevents the cover plate linkage rod from being contaminated by dust, but also improves safety during use.

[0035] In summary, the present invention has the following advantages:

[0036] 1. The cover opening and feeding operations can be completed simultaneously through a single cylinder actuator, which not only reduces energy consumption but also reduces the subsequent maintenance costs;

[0037] 2. It can prevent the leakage of garbage odor and reduce the pollution to the surrounding air;

[0038] 3. It can be applied to trash cans of different specifications and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

During use, by hiding the cover plate linkage rod 122 in the hidden space, not only can the cover plate linkage rod 122 be prevented from being contaminated by dust, but also the safety during use can be improved.

[0053] In one specific embodiment, Figure 3 As shown, the bucket rack 21 includes a bucket frame 211, a hanging tooth assembly 212, a pressure plate mechanism 213 and a trash can support plate 214. The bucket frame 211 is composed of a horizontally arranged hanging tooth fixing seat 2111 and two bucket brackets 2112 vertically connected to the hanging tooth fixing seat 2111. The hanging tooth fixing seat 2111 is connected to the garbage feeding box 1 through the bucket rack 21 fixing seat, and the flip lifting arm 23 is installed at both ends of the hanging tooth fixing seat 2111; the hanging tooth assembly 212 is installed on the side of the hanging tooth fixing seat 2111 facing the trash can. , which is used to hang the trash can; the pressure plate mechanism 213 is installed on the hanging tooth fixing seat 2111, which is used to press the upper end plane of the trash can when the hanging bucket flipping and feeding device 2 is in the unloading position to prevent the small trash can from falling into the trash feeding box 1; the trash can support plate 214 is set in two, and is connected to the lower end of the hanging bucket bracket 2112 through the same support plate fixing seat 2141, which is used to press the lower end outer wall of the trash can when the hanging bucket flipping and feeding device 2 is flipping, thereby ensuring the stability of the small trash can during the flipping process.

[0054] It should be noted that, in this embodiment, the flip lifting arm 23 can be adapted to a large trash can with a hanging bucket shaft (such as the conventional 660L trash can on the market), and the hanging tooth assembly 212 can be adapted to a small trash can with a hanging tooth groove (such as the conventional 120L or 240L small trash can on the market).

[0055] Furthermore, combined with Figure 4As shown, in this embodiment, the hanging tooth assembly 212 is arranged in two groups, and each group of hanging tooth assembly 212 is composed of a plurality of hanging tooth racks 2121 distributed at equal intervals along the length direction of the hanging tooth fixing seat 2111, and the hanging tooth rack 2121 has hanging tooth tips that match the hanging tooth grooves formed on the outer edge of the trash can. In the specific use process, the hanging tooth tips on the hanging tooth rack 2121 can be used to match with the conventional 240L small trash can on the market, and two groups of hanging tooth assemblies 212 can be set to simultaneously realize the tipping operation of two 240L small trash cans, thereby improving work efficiency.

[0056] Based on the above embodiments, Figure 4 , Figure 6 As shown, a trash can automatic sensing device 2122 is installed on one of the hanging tooth racks 2121 of the hanging tooth assembly 212, and the trash can automatic sensing device 2122 is electrically connected to the cylinder actuator 3 through a controller. Among them, the trash can automatic sensing device 2122 includes a bucket push-in place sensor and a bucket hang-in place sensor, both of which use proximity switches. When the bucket push-in place sensor and the bucket hang-in place sensor receive signals at the same time, the cylinder actuator 3 can be automatically triggered, so that the cylinder actuator 3 controls the hanging bucket flipping feeding device 2 to perform a tilting operation, so that there is no need for manual control of the operation button, which is more intelligent.

[0057] like Figure 3 , Figure 5 As shown, the pressing plate mechanism 213 includes an L-shaped pressing plate 2131, a cover plate hinge seat 2132 connecting the pressing plate 2131 and the hanging tooth fixing seat 2111, and a cover plate return spring 2133 connecting the cover plate hinge seat 2132 and the hanging bucket bracket 2112. The cover plate hinge seat 2132 is rotatably mounted on the side of the hanging tooth fixing seat 2111 facing the garbage feeding box 1, and one end of the cover plate return spring 2133 is connected to the middle of the cover plate hinge seat 2132, and the other end is fixed to the side wall of the hanging bucket bracket 2112. Therefore, when the hanging bucket flip feeding device 2 is in the initial position, under the action of the cover plate return spring 2133, the opening angle of the garbage bin pressing plate 2131 and the hanging tooth assembly 212 can be maximized, thereby avoiding affecting the cooperation between the small garbage bin and the hanging tooth bracket 2121.

[0058] In one specific embodiment, Figure 6As shown, the connecting rod lifting frame 22 includes two groups of parallel four-bar linkage mechanisms 221, each group of parallel four-bar linkage mechanisms 221 includes a first connecting rod 2211 connected to a tooth fixing seat 2111 through a connecting rod fixing seat at one end, a second connecting rod 2212 hinged to the middle of the first connecting rod 2211 at one end, a third connecting rod 2213 hinged to the other end of the second connecting rod 2212 at one end, and a fourth connecting rod 2214 hinged to the other end of the first connecting rod 2211 at one end and hinged to the middle of the third connecting rod 2213 at the other end, the other end of the third connecting rod 2213 is connected to the cover plate linkage rod 122 through a connecting sleeve, a linkage support rod 2215 is connected between the two third connecting rods 2213, and the piston rod of the cylinder actuator 3 is hinged to the linkage support rod 2215. After the cylinder actuator 3 is started, the two parallel four-bar linkages 221 can be simultaneously controlled to move through the linkage support rod 2215 to achieve the tipping operation of the hanging barrel flip feeding device 2. Among them, the parallel four-bar linkage 221 can meet the effect of achieving a larger adjustment range within a shorter stroke.

[0059] Based on the above embodiments, Figure 7-8 As shown, the fourth connecting rod 2214 is vertically arranged on the outer side wall of the garbage feeding box 1 through a connecting rod mounting seat, and a descending position sensor 22141 and a flipping position sensor 22142 are installed on the outer side wall. The descending position sensor 22141 is close to the hinge point between the fourth connecting rod 2214 and the first connecting rod 2211, and the flipping position sensor 22142 is close to the hinge point between the fourth connecting rod 2214 and the third connecting rod 2213. In this embodiment, the descending position sensor 22141 and the flipping position sensor 22142 are both proximity switches.

[0060] When the sensor 22141 that has dropped into position senses the first connecting rod 2211, it indicates that the hanging bucket flipping and feeding device 2 has dropped into position, and the cylinder actuator 3 is automatically closed at this time, so that the next trash can tipping operation can be carried out; when the sensor 22142 that has flipped into position senses the third connecting rod 2213, it indicates that the hanging bucket flipping and feeding device 2 has flipped into position, and the cylinder actuator 3 is automatically closed at this time, so as to prevent the trash can from tilting excessively and falling into the trash feeding box 1.

[0061] The working process and beneficial effects of the present invention are as follows: when it is necessary to tip over a large trash can, first push the large trash can toward the bucket hanging frame 21, then clamp the bucket hanging shafts on both sides of the trash can through the flip lifting arms 23, and after the trash can is clamped stably, start the cylinder actuator 3, and drive the large trash can to tip over through the connecting rod lifting frame 22, and at the same time, the cover plate 12 is opened through the linkage between the cover plate linkage rod 122 and the connecting rod lifting frame 22.

[0062] When it is necessary to tip the small trash can, first push the small trash can toward the hanging tooth fixing seat 2111, and hang the small trash can on the hanging tooth tip of the hanging tooth frame 2121. When the bucket is pushed into place sensor and the bucket is hung into place sensor receive signals at the same time, the cylinder actuator 3 is automatically triggered, so that the cylinder actuator 3 controls the hanging bucket flipping and feeding device 2 to flip, completing the tipping operation of the small trash can. At the same time, the cover plate 12 is opened through the linkage between the cover plate linkage rod 122 and the connecting rod lifting frame 22.

[0063] In summary, the single cylinder actuator 3 is used to simultaneously complete the opening of the cover plate 12 and the feeding operation, which not only has low energy consumption, but also reduces the subsequent maintenance costs, and effectively prevents the leakage of garbage odor and reduces the pollution to the surrounding air.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
