Description

Technical Field

[0001] This utility model relates to the field of feed trucks, and in particular to a hydraulic cylinder opening mechanism for feed trucks. Background Technology

[0002] In the bulk feed transportation industry, the cargo compartment opening mechanism of feed trucks plays a crucial role in the efficient and precise unloading of feed. Traditional feed truck opening mechanisms have several drawbacks. Firstly, they are manually operated. Operators manually open or close the cargo door. This method is not only inefficient and labor-intensive, but also poses significant safety risks during operation.

[0003] Secondly, some of the opening mechanisms that use simple mechanical transmissions have inadequate structural design. The opening and closing of the bin doors are not smooth, and jamming frequently occurs. This not only affects the unloading speed, but also, with prolonged jamming and friction, can easily lead to accelerated wear of components, shorten the service life of the opening mechanism, and increase maintenance costs.

The rocker arm shaft assembly includes a first rocker arm shaft arranged in the first compartment and a second rocker arm shaft arranged in the second compartment. The first rocker arm shaft and the second rocker arm shaft are coaxially arranged. The second rocker arm shaft is connected to the hydraulic component. The first rocker arm shaft passes through the second rocker arm shaft and is connected to the hydraulic component.

[0006] The effects achieved by the above-mentioned components are as follows: by setting the tank body to be divided into a first compartment and a second compartment, and the opening mechanism including a rocker arm shaft assembly, a discharge compartment door and a hydraulic component, the first rocker arm shaft and the second rocker arm shaft in the rocker arm shaft assembly are coaxially arranged and the first rocker arm shaft passes through the second rocker arm shaft and is connected to the hydraulic component, the orderly control of different compartments of the feed truck is realized, the space utilization rate is improved, and the layout of the entire opening mechanism is more compact and reasonable, laying the foundation for subsequent accurate unloading and efficient development, while ensuring the stability of transmission and reducing the risk of failure caused by unreasonable component layout.

[0007] Preferably, the hydraulic assembly includes a cylinder mounting bracket, a first hydraulic component disposed at the lower end of the cylinder mounting bracket and connected to the first rocker arm shaft, and a second hydraulic component disposed adjacent to the first hydraulic component and connected to the second rocker arm shaft.

[0008] The aforementioned components achieve the following effect: by setting up a hydraulic assembly including a cylinder mounting bracket, a first hydraulic component connected to the first rocker arm shaft, and a second hydraulic component connected to the second rocker arm shaft, independent drive control of the discharge doors of the first and second compartments is realized. This allows for precise control of the opening and closing of the two compartment doors according to actual unloading needs, greatly improving the accuracy and efficiency of feed unloading. It is particularly suitable for scenarios involving the separate unloading of multiple different types of feed, avoiding mutual interference during the unloading of different feeds.

[0009] Preferably, the first hydraulic component includes an opening cylinder axially connected to the lower end of the cylinder mounting bracket, a pin interface located at the lower end of the cylinder, and a transmission rocker arm axially connected to the pin interface.

[0011] Preferably, the first hydraulic component and the second hydraulic component have the same structure.

[0012] The aforementioned components achieve the following effects: by setting the first and second hydraulic components to have identical structures, standardization of parts during the manufacturing process is facilitated, reducing production and maintenance costs. When repairing or replacing parts, there is no need to prepare multiple parts of different specifications, improving maintenance efficiency. Simultaneously, the identical structure ensures the consistency and coordination of the opening actions of the two compartments, contributing to a smooth overall unloading process.

[0013] Preferably, the first hydraulic component and the second hydraulic component are connected to the first rocker arm shaft and the second rocker arm shaft respectively via a transmission rocker arm.

[0014] The aforementioned components achieve the following effect: by setting the first and second hydraulic components to be connected to the first and second rocker arm shafts respectively via a transmission rocker arm, the power transmission path is further optimized. This allows the power generated by the hydraulic components to be efficiently and accurately transmitted to the rocker arm shaft, thereby driving the discharge bin door.

[0015] Preferably, both the lower ends of the first rocker arm shaft and the second rocker arm shaft are provided with material discharge bin doors.

[0016] The aforementioned components achieve the following effect: by arranging discharge hopper doors at the lower ends of both the first and second rocker arm shafts, each hopper has an independent corresponding discharge port, further enabling precise control over feed unloading in each hopper.

[0028] In this embodiment 1,

[0029] like Figures 1 to 4 As shown, this utility model provides a hydraulic cylinder opening mechanism for a feed truck, including a tank body 1 and an opening mechanism. The tank body 1 is divided into a first compartment 2 and a second compartment 3. The opening mechanism includes a rocker arm shaft assembly 4, a discharge compartment door 5 arranged at the lower end of the rocker arm shaft assembly 4, and a hydraulic component 6 arranged on the outside of the tank body 1 and connected to the rocker arm shaft assembly 4 in a transmission manner. The rocker arm shaft assembly 4 includes a first rocker arm shaft 7 arranged in the first compartment 2 and a second rocker arm shaft 8 arranged in the second compartment 3.

The first rocker arm shaft 7 passes through the second rocker arm shaft 8 and is connected to the hydraulic component 6.

[0030] By setting the tank body 1 to be divided into a first compartment 2 and a second compartment 3, and the opening mechanism including a rocker arm shaft assembly 4, a discharge compartment door 5 and a hydraulic assembly 6, the first rocker arm shaft 7 and the second rocker arm shaft 8 in the rocker arm shaft assembly 4 are coaxially arranged and the first rocker arm shaft 7 passes through the second rocker arm shaft 8 and is connected to the hydraulic assembly 6, the orderly control of different compartments of the feed truck is realized, the space utilization rate is improved, and the layout of the entire opening mechanism is more compact and reasonable, laying the foundation for subsequent accurate unloading and efficient development, while ensuring the stability of transmission and reducing the risk of failure caused by unreasonable component layout.

[0031] The hydraulic assembly 6 includes a cylinder mounting bracket 9, a first hydraulic component 10 disposed at the lower end of the cylinder mounting bracket 9 and connected to the first rocker arm shaft 7, and a second hydraulic component 11 disposed adjacent to the first hydraulic component 10 and connected to the second rocker arm shaft 8.

[0032] By configuring the hydraulic assembly 6, which includes a cylinder mounting bracket 9, a first hydraulic component 10 connected to the first rocker arm shaft 7, and a second hydraulic component 11 connected to the second rocker arm shaft 8, independent drive control of the discharge doors 5 of the first compartment 2 and the second compartment 3 is achieved. This allows for precise control of the opening and closing of the doors of the two compartments according to actual unloading needs, greatly improving the accuracy and efficiency of feed unloading. It is particularly suitable for scenarios involving the separate unloading of multiple types of feed, avoiding mutual interference during the unloading of different feeds.

[0033] The first hydraulic component 10 includes an opening cylinder 12 axially connected to the lower end of the cylinder fixing frame 9, a pin shaft interface 13 located at the lower end of the cylinder, and a transmission rocker arm 14 axially connected to the pin shaft interface 13.

The opening cylinder 12 provides power, and the axial connection between the pin interface 13 and the transmission rocker arm 14 ensures effective force transmission during power transmission and can flexibly adapt to different angle movement requirements, ensuring that the hatch can open and close smoothly and reducing the occurrence of jamming.

[0035] The first hydraulic component 10 and the second hydraulic component 11 have the same structure.

[0036] By setting the first hydraulic component 10 and the second hydraulic component 11 to have the same structure, the standardization of parts in the manufacturing process is facilitated, reducing production and maintenance costs. When repairing or replacing parts, it is unnecessary to prepare multiple parts of different specifications, improving maintenance efficiency. At the same time, the identical structure ensures the consistency and coordination of the opening actions of the two compartments, which is conducive to the smooth operation of the overall unloading process.

[0037] The first hydraulic component 10 and the second hydraulic component 11 are respectively connected to the first rocker arm shaft 7 and the second rocker arm shaft 8 via the transmission rocker arm 14.

[0038] By configuring the first hydraulic component 10 and the second hydraulic component 11 to be connected to the first rocker arm shaft 7 and the second rocker arm shaft 8 respectively via the transmission rocker arm 14, the power transmission path is further optimized. This allows the power generated by the hydraulic component 6 to be efficiently and accurately transmitted to the rocker arm shaft, thereby driving the discharge bin door 5 to move. The transmission rocker arm 14 plays a good role in force transmission and direction conversion, ensuring that the bin door opens and closes in a predetermined manner and speed, thus improving the operating accuracy of the entire opening mechanism.

[0039] Both the first rocker arm shaft 7 and the second rocker arm shaft 8 are provided with a material discharge hopper door 5 at their lower ends.

[0040] By arranging discharge doors 5 at the lower ends of both the first rocker arm shaft 7 and the second rocker arm shaft 8, each compartment has an independent discharge port, further enabling precise control of feed unloading in each compartment. Different compartments can unload at different times and speeds according to actual needs, greatly improving the flexibility of feed transportation and unloading, and meeting diverse feed distribution requirements.

[0041] In this embodiment 2,

[0042] like Figures 1 to 4As shown, the tank body 1 is equipped with a first compartment 2 and a second compartment 3. The opening mechanism includes a rocker arm shaft assembly 4, a discharge compartment door 5, and a hydraulic assembly 6. The first rocker arm shaft 7 and the second rocker arm shaft 8 are coaxial and nested, resulting in a compact and reasonable structure with high space utilization. This lays the foundation for precise unloading and the miniaturization and efficiency of the equipment, ensuring transmission stability. The hydraulic assembly 6 includes a cylinder fixing bracket 9, which, along with a first hydraulic component 10 and a second hydraulic component 11, connects the first rocker arm shaft 7 and the second rocker arm shaft 8 respectively. This enables independent and precise drive control of the discharge compartment doors 5 of the two compartments, avoiding interference from different feed unloading methods. The design of the opening cylinder 12, pin shaft interface 13, and transmission rocker arm 14 of the first hydraulic component 10 ensures stable and reliable power transmission, adapting to multi-angle movement requirements. The first hydraulic component 10 and the second hydraulic component 11 have identical structures, facilitating component standardization, reducing production and maintenance costs, and ensuring consistent opening actions. The transmission rocker arm 14 connects to the rocker arm shaft, optimizing the power transmission path and improving operational accuracy. Both rocker arm shafts are equipped with feed bin doors 5 at their lower ends. Combined with independent drive control, this enables precise control of feed unloading in each bin, meeting diverse delivery needs and greatly improving the flexibility and efficiency of feed truck unloading.

[0043] In this embodiment 3,

[0044] like Figures 1 to 4 As shown, when the hatch door needs to be opened, the opening cylinder 12, which is axially connected to the lower end of the cylinder mounting bracket 9, serves as the power source for the first hydraulic component 10 and begins to generate power output. The pin interface 13 at the lower end of the opening cylinder 12 is axially connected to the transmission rocker arm 14, so that the power output by the opening cylinder 12 can be effectively transmitted to the transmission rocker arm 14.

[0045] Similarly, the second hydraulic component 11, which has the same structure as the first hydraulic component 10, also operates in the same manner. Its opening cylinder 12 generates power, which is transmitted to the transmission rocker arm 14 through the pin interface 13.

[0046] The first hydraulic component 10 and the second hydraulic component 11 are respectively connected to the first rocker arm shaft 7 and the second rocker arm shaft 8 via a transmission rocker arm 14. In this way, the transmission rocker arm 14 of the first hydraulic component 10 transmits power to the first rocker arm shaft 7, and the transmission rocker arm 14 of the second hydraulic component 11 transmits power to the second rocker arm shaft 8.

[0047] The first rocker arm shaft 7 is located in the first compartment 2, and the second rocker arm shaft 8 is located in the second compartment 3, and the two are coaxially arranged. The first rocker arm shaft 7 passes through the second rocker arm shaft 8 and is connected to the hydraulic assembly 6. When power is transmitted to the rocker arm shaft, the rocker arm shaft begins to rotate.

[0048] Both the first rocker arm shaft 7 and the second rocker arm shaft 8 have discharge bin doors 5 located at their lower ends. The rotation of the rocker arm shafts opens or closes the discharge bin doors 5. Since the first and second hydraulic components 11 can be controlled independently, the opening and closing of the discharge bin doors 5 in the first compartment 2 and the second compartment 3 can be precisely controlled according to actual unloading needs. For example, when transporting multiple types of feed, the feed in different compartments can be unloaded separately, avoiding mutual interference during unloading and achieving precise unloading.
