Description

Technical Field

[0001] This utility model relates to the technical field of bulk feed transport vehicles, specifically a rotary bottom door opening mechanism for bulk feed vehicles. Background Technology

[0002] Bulk feed transport vehicles, as specialized vehicles for transporting feed, are increasingly widely used in feed transportation. They typically use dedicated bulk solid material transport tank trucks with an approximately V-shaped bottom. A horizontal discharge device, such as a screw conveyor or scraper conveyor, is installed longitudinally inside the tank. A discharge gate is located above the horizontal discharge device; after the gate is opened, the bulk material slides through the gap into the horizontal discharge device and is then delivered to the outside of the transport tank truck.

[0003] The drawback of the existing technology is that the bottom door opening device adopts a lifting structure, which is limited by the structural size. The channel after the door is opened is small. When unloading feed with poor flowability, the feed is prone to accumulate at the channel opening and cannot enter the lower horizontal discharge device, affecting the discharge efficiency or even preventing discharge. Utility Model Content

[0004] The purpose of this invention is to propose a rotary bottom door opening mechanism for bulk feed trucks, which is easy to control, has a large opening range for the feed inlet, and ensures smooth material flow, thereby guaranteeing the stable operation of the bulk feed transport truck.

[0005] The technical solution adopted in this utility model is: a rotary bottom opening mechanism for bulk feed trucks, wherein the bottom of the silo has a partition plate and a side plate, as well as a horizontal discharge device mounting hole located at the lower end of the partition plate.

[0006] A drive shaft and a driven shaft that are parallel to each other are fixed above the mounting hole of the horizontal discharge device on the partition plate;

[0007] The drive shaft is movably connected to the right compartment door panel via a hinge, and the driven shaft is movably connected to the left compartment door panel via a hinge; both the left and right compartment door panels are arc-shaped, with at least one end of each panel overlapping, and the other end forming a discharge port that can be opened or closed between it and the side panel.

[0008] The bottom of the compartment is equipped with an arc-shaped limiting mechanism that restricts the movement trajectory of the left and right compartment doors;

[0009] The drive shaft and the driven shaft are driven by a gear pair that can drive the left and right compartment doors to rotate in opposite directions or in the overlapping state, so as to open or close the discharge port.

[0010] As a preferred option, the lower sides of the left and right compartment doors are provided with curved stiffeners.

[0011] As a preferred embodiment, the hinge includes a connecting rod and a swing arm that are rotatably connected by a pin. The connecting rod is rotatably connected to the left or right compartment door panel by the pin, and the swing arm is fixedly connected to the drive shaft or the driven shaft.

[0012] As a preferred option, the two hinges are staggered in the axial direction of the drive shaft.

[0013] As a preferred embodiment, the bottom of the silo is equipped with a silo door drive mechanism that connects to and drives the drive shaft to rotate.

[0014] As a preferred embodiment, the arc-shaped limiting mechanism includes a left compartment door limiting component for limiting the movement trajectory of the left compartment door panel and a right compartment door limiting component for limiting the movement trajectory of the right compartment door panel.

[0015] As a preferred embodiment, the right compartment door limiting assembly includes a first arc-shaped limiting plate and a second arc-shaped limiting plate fixed on the compartment plate; an arc-shaped limiting cavity is formed between the first arc-shaped limiting plate and the second arc-shaped limiting plate, and the right compartment door plate slides within the limiting cavity.

[0016] As a preferred embodiment, the left compartment door limiting assembly includes a third arc-shaped limiting plate fixed on the left compartment door panel, and an arc-shaped limiting cavity is formed between the third arc-shaped limiting plate and the left compartment door panel, and the right compartment door panel slides within the limiting cavity.

[0017] As a preferred option, the gear pair is always located below the left and right compartment panels.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This design achieves the opening and closing of the bins by the opposite synchronous rotation of the left and right arc-shaped bins. When open, the left and right bins overlap each other, thus providing a larger opening channel to meet the discharge of feed with poor flowability. It can be opened manually or automatically by adding drive components such as hydraulic cylinders, pneumatic cylinders, and electric push rods, making it easy to control.

[0020] 2. Installed inside the bottom of the silo, it does not take up space;

[0021] 3. The curved door panel helps maintain the flow of materials and is less prone to clogging. Attached Figure Description

[0028] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," etc., used in this utility model patent application specification and claims do not express a quantity limitation, but rather indicate the presence of at least one; the terms "first," "second," and "third," as used herein, should not be considered as a limitation on the order of components, but are merely for distinguishing different components; the terms "comprising" or "including," etc., indicate that the elements or objects preceding "comprising" or "including" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0030] To more clearly describe the specific structural components of the rotary bottom door opening mechanism used in bulk feed trucks, in conjunction with the attached... Figure 1-4 This embodiment is described as follows:

[0031] like Figure 1-4As shown, a rotary bottom door opening mechanism for a bulk feed truck includes a bin bottom with a partition plate 15, a side plate 16, and a horizontal discharge device mounting hole at the lower end of the partition plate 15. A drive shaft 12 and a driven shaft 13, parallel to each other, are fixed on the partition plate 15 above the horizontal discharge device mounting hole. The drive shaft 12 is movably connected to a right bin door plate 9 via a hinge, and the driven shaft 13 is movably connected to a left bin door plate 1 via a hinge. Both the left and right bin door plates 1 and 9 are arc-shaped, with at least one end partially overlapping, and the other end forming an opening 17 between itself and the side plate 16. An arc-shaped limiting mechanism is provided inside the bin bottom to restrict the movement trajectory of the left and right bin door plates 1 and 9. The drive shaft 12 and the driven shaft 13 are driven by a gear pair that can rotate the left and right bin door plates 1 and 9 in opposite directions when they are overlapping, thereby opening or closing the discharge port 17.

[0032] In use, the drive shaft 12 is rotated manually or electrically, and the driven shaft 13 is driven to rotate in the opposite direction by the gear pair. The drive shaft 12 drives the right compartment door panel 9 to rotate along the trajectory defined by the arc-shaped limiting mechanism through the hinge, and the driven shaft 13 drives the left compartment door panel 1 to rotate along the trajectory defined by the arc-shaped limiting mechanism through the hinge. When the discharge port 17 is opened, the left compartment door panel 1 and the right compartment door panel 9 move towards each other in the overlapping state, and the non-overlapping ends of the left compartment door panel 1 and the corresponding side panels 1 6. When the material is separated, the discharge port 17 is opened. As the overlap area increases, the discharge ports on both sides gradually increase in size. When the discharge port 17 is closed, the left compartment door panel 1 and the right compartment door panel 9 move in opposite directions while overlapping. As the overlap area decreases, the discharge ports on both sides gradually decrease in size until the non-overlapping ends of the left compartment door panel 1 and the right compartment door panel 9 are in close contact with the corresponding side panels 16. When the discharge port 17 is opened, the material at the bottom of the compartment is diverted by the arc surface on the upper side of the left compartment door panel 1 and the right compartment door panel 9 and flows out from the discharge ports 17 on both sides respectively.

[0033] See Figure 3 In the above embodiments, the arc-shaped limiting mechanism includes a left compartment door limiting component for limiting the movement trajectory of the left compartment door panel 1 and a right compartment door limiting component for limiting the movement trajectory of the right compartment door panel 9.

[0034] For example, the right compartment door limiting assembly includes a first arc-shaped limiting plate 5 and a second arc-shaped limiting plate 10 fixed on the compartment plate 15; an arc-shaped limiting cavity is formed between the first arc-shaped limiting plate 5 and the second arc-shaped limiting plate 10, and the right compartment door plate 9 slides within the limiting cavity;

[0035] The left compartment door limiting assembly includes a third arc-shaped limiting plate 3 fixed on the left compartment door panel 1. An arc-shaped limiting cavity is formed between the third arc-shaped limiting plate 3 and the left compartment door panel 1, and the right compartment door panel 9 slides within the limiting cavity.

[0036] See Figure 2Arc-shaped ribs are provided on the lower side of the left compartment door panel 1 and the right compartment door panel 9 to improve the strength and load-bearing capacity of the door panels. The hinge can be directly connected to the door panel or connected to the arc-shaped ribs. The arc-shaped ribs include the left compartment door arc-shaped rib 2 connected to the left compartment door panel 1 and the right compartment door arc-shaped rib 8 connected to the right compartment door panel 9.

[0037] See Figure 4 The gear pair includes a drive gear 11 fixedly connected to the drive shaft 12 and a driven gear 14 fixed on the driven shaft 13. The drive gear 11 and the driven gear 13 mesh. The gear pair is always located below the left compartment door 1 and the right compartment door 9. When the discharge port 17 is open, the material cannot directly contact the gear pair.

[0038] See Figure 2 and Figure 3 The hinge specifically includes a connecting rod 4 and a swing arm 6 rotatably connected by a pin. The connecting rod 4 is rotatably connected to the left door panel 1 or the right door panel 9 by a pin 7, and the swing arm 6 is fixedly connected to the drive shaft 12 or the driven shaft 13. The running trajectory of the door is not an arc motion with the drive shaft 12 and the driven shaft 13 as the center. Therefore, the connecting rod 4 and the pin 7 are designed to form a two-bar hinge to convert the rotational motion of the drive shaft 12 and the driven shaft 13 into the motion of the door panel along the same arc, ensuring that the left door panel 1 or the right door panel 9 runs stably in the overlapping and fitting state.

[0039] To reduce interference between the two hinges when they move toward each other, the two hinges are staggered in the axial direction of the drive shaft 12.

[0040] In the above embodiment, the bottom of the silo is provided with a silo door drive mechanism that connects to and drives the drive shaft 12 to rotate. The silo door drive mechanism can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0041] The parts not described in detail in the above embodiments are existing technologies.

[0042] It should be noted that although the present invention has been described through the above embodiments, there may be other various embodiments of the present invention. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but all such changes and modifications should fall within the scope of protection of the appended claims and their equivalents.
