[0025] To make the purpose, technical solutions, and advantages of this practical embodiment more clear, the technical solutions in this practical embodiment are clearly and completely described. Obviously, the described embodiments are part of the embodiments of this practical, not all of them. Based on the embodiments in this practical, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this practical.

[0026] The present application provides a flip-top dust cover that addresses the technical issues with existing hopper dust covers on waste disposal equipment, such as damage from impact when a garbage truck dumps garbage, and the inability to properly seal the hopper due to excessive rotation. In actual use, this reduces the risk of dust cover damage and avoids dust protection failure caused by excessive rotation and inability to properly seal the hopper.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1-6, a flip-type dust cover, comprising: a hopper 1 for storing garbage; a first dust cover 2, flip-connected to the hopper 1, and the first dust cover 2 is used to seal the hopper 1; a second dust cover 3, rotatably connected to the first dust cover 2, and the rotation direction of the second dust cover 3 is opposite to that of the first dust cover 2, and the second dust cover 3 is used to seal the hopper 1; a sleeve 7, at least one of which is rotatably connected to the first dust cover 2, and the sleeve 7 is in the hopper 1; a sleeve rod 8, at least one of which is slidably connected to the sleeve 7 at one end, and the other end of the sleeve rod 8 passes through the sleeve 7 and is rotatably connected to the second dust cover 3; a second spring 9, stably installed in the sleeve 7, and the second spring 9 is used to reduce the impact force of garbage on the second dust cover 3.

[0029] Through the structural cooperation of the flipping connection between the first dust cover 2 and the hopper 1, the rotational connection between the second dust cover 3 and the first dust cover 2, the rotational connection between the sleeve 7 and the first dust cover 2, the sliding connection between the sleeve rod 8 and the sleeve 7, and the second spring 9 installed in the sleeve 7, it is achieved that when garbage impacts the second dust cover 3, the second spring 9 can slow down the impact force of the garbage on the second dust cover 3, thereby protecting the dust cover structure and improving the service life of the dust cover.

[0030] At least one push rod 4 is provided, and one end of the push rod 4 is rotatably connected to the hopper 1, and the other end is rotatably connected to the first dust cover 2. The push rod 4 is used to drive the first dust cover 2 to rotate.

[0031] By rotating one end of the push rod 4 with the hopper 1 and the other end with the first dust cover 2, the push rod 4 can drive the first dust cover 2 to rotate, thereby conveniently opening and closing the first dust cover 2 and improving the convenience of operation.

[0032] There are at least two connecting keys 6 , and the two connecting keys 6 are stably connected to the first dust cover 2 and the second dust cover 3 respectively. The two connecting keys 6 are rotatably connected to the sleeve 7 and the sleeve rod 8 respectively.

[0033] By means of two connecting keys 6 which are stably connected to the first dust cover 2 and the second dust cover 3 respectively and are rotationally connected to the sleeve 7 and the sleeve rod 8 respectively, the first dust cover 2, the second dust cover 3, the sleeve 7 and the sleeve rod 8 are connected together, thereby ensuring the coordinated movement between the components and improving the stability of the structure.

[0034] At least one first spring 5 is provided, and one end of the first spring 5 is stably connected to the first dust cover 2 , and the other end is stably connected to the hopper 1 . The first spring 5 is used to provide a reset pulling force for the first dust cover 2 .

[0035] By stably connecting one end of the first spring 5 to the first dust cover 2 and the other end to the hopper 1, the first spring 5 provides a reset pull for the first dust cover 2, ensuring that the first dust cover 2 can be reliably reset after opening, thereby improving the reliability of the seal.

[0036] When the first dust cover 2 is closed, the first spring 5 is in a compressed state.

[0037] When the first dust cover 2 is closed, the first spring 5 is in a compressed state, so as to avoid the first dust cover 2 being not fully expanded when the first dust cover 2 is opened, thereby affecting the use of the first dust cover 2.

[0038] The first dust cover 2 and the second dust cover 3 are both adapted to the hopper 1 .

[0039] The structure in which the first dust cover 2 and the second dust cover 3 are adapted to the hopper 1 can completely cover the hopper 1, effectively preventing dust and odor from escaping and improving the dustproof effect.

[0040] The length of the sleeve 7 is adapted to the length of the sleeve rod 8 .

[0041] By adapting the length of the sleeve 7 to the length of the sleeve rod 8, the sleeve rod 8 can slide stably in the sleeve 7, ensuring the connection stability between the second dust cover 3 and the first dust cover 2 and improving the reliability of the entire dust cover system.

[0042] The first dust cover 2 and the hopper 1 are connected via a hinge.

[0043] By adopting a hinge connection structure between the first dust cover 2 and the hopper 1, the first dust cover 2 can be flexibly flipped relative to the hopper 1, which is convenient for opening and closing operations. At the same time, the hinge connection is relatively stable, ensuring the position stability of the first dust cover 2 when sealing the hopper 1.

[0044] The push rod 4 is located outside the hopper 1 .

[0045] By arranging the push rod 4 outside the hopper 1, the push rod 4 is isolated from the garbage in the hopper 1, avoiding damage and contamination of the push rod 4 by the garbage, ensuring that the push rod 4 can drive the first dust cover 2 to rotate stably for a long time, and improving the reliability and service life of the entire device.

[0046] The elastic force of the second spring 9 should be greater than the gravity of the first dust cover 2 .

[0047] By making the elastic force of the second spring 9 greater than the gravity of the first dust cover 2, it is achieved that when there is no garbage impact, the second spring 9 can provide an upward supporting force to the second dust cover 3 connected to the first dust cover 2, ensuring that the dust cover system is in a stable state. When there is garbage impact, the second spring 9 can better play a buffering role and protect the dust cover from damage.

[0048] After the garbage is poured into the hopper 1, if there is garbage impacting the second dust cover 3, the sleeve rod 8 slides in the sleeve 7, and the second spring 9 in the sleeve 7 is compressed, which reduces the impact force of the garbage on the second dust cover 3; when the garbage is dumped, the push rod 4 retracts, and the first spring 5 provides a pulling force to the first dust cover 2, prompting the first dust cover 2 to rotate and close, so that the first dust cover 2 and the hopper 1 are sealed, and the first spring 5 is in a compressed state. During the whole process, the first dust cover 2 and the second dust cover 3 cooperate with each other to effectively prevent the garbage from impacting and damaging the dust cover, and at the same time avoid excessive rotation and failure to cover and seal the hopper 1, thereby ensuring the dustproof effect of the garbage disposal equipment.

[0049] The control device, power supply device and other structures required above are all existing technologies and are non-essential technical features in this application, so they are not described or drawn in the documents and drawings of this application; and the figures shown in the drawings are example figures, and their purpose is only to more intuitively show the key structure and connection relationship of a flip-type dust cover of the utility model; in actual application, the appearance and size of the device can be adjusted and optimized according to specific needs.

[0050] To sum up, compared with the existing technology, the present invention has the following beneficial effects: through the flip connection between the first dust cover and the hopper, the rotation connection between the second dust cover and the first dust cover, and the cooperation of the sleeve, the sleeve rod and the second spring, when the garbage impacts the second dust cover, the second spring can effectively reduce the impact force, reducing the risk of damage to the dust cover due to the impact of the garbage; the first spring provides a reset pulling force for the first dust cover, avoiding the first dust cover from rotating in the opposite direction when the push rod is pulled, and at the same time cooperates with the second spring to provide a thrust to the second dust cover, preventing the second dust cover from sliding in the opposite direction, ensuring that the first dust cover and the second dust cover can fit the hopper tightly.

[0051] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
