Description

Technical Field

[0001] This invention relates to the field of material transportation technology, specifically to a material transportation silo structure and a transportation device having the same. Background Technology

[0002] In some production settings, it is often necessary to transport materials with no fixed shape, which is where transport vehicles come in. Material transport silos are a common type of container suitable for transporting materials with no fixed shape. They are usually used in conjunction with transport vehicles. Specifically, the transport silo is installed on the transport vehicle, the material is loaded into the transport silo, and then the transport vehicle transports the silo to the target location, where the material is then unloaded.

[0003] In traditional machinery industries, when transporting heavy, hard materials (such as iron filings), the wear and tear on transport containers is significant, resulting in a generally short service life for transport vehicles. Therefore, expensive transport vehicles equipped with electrified tools for loading and unloading are typically not used; instead, simpler, lower-cost vehicles are employed. However, after transporting the materials to the destination using these vehicles, manual labor is required to unload the materials from the transport container, which is quite laborious.

[0004] Therefore, this application provides a more labor-saving material transport silo structure to solve the above-mentioned technical problems. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defect that it is laborious to turn the materials out of the transport bin by manpower in the prior art, so as to provide a material transport bin structure that is more labor-saving, does not use assistive tools, and therefore has a lower cost.

[0006] The present invention also provides a transport device having the above-described material transport silo structure.

[0007] Therefore, the present invention provides a material transport silo structure, comprising:

[0008] The hopper body has a hopper bottom surface and two parallel and opposite hopper side plates disposed on both sides below the hopper bottom surface;

[0009] The hopper base is suitable for fixed installation on a transport device and for supporting the hopper body.

[0010] A tilting frame is rotatably mounted on the hopper base via a tilting structure and rotatably connected to the two hopper side plates via a rotating structure; the tilting frame has a flat top surface; after being mounted on the hopper base, the tilting frame has a first tilting state at a first tilt angle and a second tilting state at a second tilt angle; the second tilt angle is greater than the first tilt angle.

[0011] The hopper body has a horizontal state supported by the hopper base, a first tilted state supported on the tilting frame in a first tilted state, and a second tilted state supported on the tilting frame in a second tilted state.

[0012] When the hopper body is in the horizontal state and the first inclined state, the center of gravity of the hopper body is between the rotating structure and the tilting structure; when the hopper body is in the second inclined state, the center of gravity of the hopper body is outside the tilting structure.

[0014] In the initial state, the hopper body is locked to the hopper base by the locking structure, and the hopper body is in a horizontal state;

[0015] After the locking structure is unlocked, the hopper body automatically rotates to the first tilt state through the rotating structure. At this time, the bottom surface of the hopper body contacts the top surface of the tilting frame.

[0016] Under the action of external force, the hopper body and the tilting frame rotate simultaneously around the tilting structure, tilting the hopper body from the first tilting state to the second tilting state.

[0017] Optionally, the hopper base includes:

[0018] A flip-mount slot is provided for the flip frame to be flipped upside down for mounting.

[0019] A support groove is located on the side of the flip mounting groove away from the flipping direction, and is used together with the flip mounting groove to support the flipping frame in the first flipping state;

[0021] Optionally, the flipping frame includes:

[0022] The side panels are flip-up; there are two panels, positioned opposite each other.

[0023] The flip shaft is fixedly connected to the two flip side plates at both ends and can be flipped and installed on the flip mounting slot.

[0024] There are two flip-through holes, which are respectively opened opposite each other at the ends of the two flip-side plates away from the flip direction;

[0025] The rotating cylinder is fixedly connected at both ends to two rotating side plates with rotating through holes, and the central axis of the rotating cylinder coincides with the central axis of the rotating through holes; it is movably supported inside the support groove.

[0026] Optionally, the flipping structure further includes:

[0027] The door-shaped mounting plate has an inverted U-shaped groove in the middle.

[0028] There are two first mounting holes, which are respectively opened on both sides of the inverted U-shaped groove;

[0029] There are two second mounting holes, which are respectively opened on both sides of the flip mounting slot;

[0030] After the mounting bolts pass through the first mounting hole and the second mounting hole, the gate-shaped mounting plate is fixedly installed on the hopper base, and the flipping shaft is rotatably restricted between the flipping mounting groove and the inverted U-shaped groove.

[0031] Optionally, the rotating structure includes:

[0032] There are two rotating holes, which are respectively opened opposite to each other on the side plate of the hopper;

[0033] The rotating shaft passes through the flipping cylinder and extends outwards a certain length from the two rotating holes.

[0034] Optional, also includes:

[0035] A baffle plate is fitted onto the portion of the rotating shaft that extends through the rotating hole.

[0036] A limiting hole is formed on the portion of the rotating shaft that extends out of the baffle.

[0037] A limiting clip is inserted inside the limiting hole to prevent the baffle from slipping out.

[0038] Optionally, it also includes a limiting structure for limiting the tilting frame in the second tilting state; the limiting structure includes:

[0039] The limiting rod is fixedly connected at both ends to the ends of the two flipping side plates that are opposite to the flipping cylinder;

[0040] A limiting groove is provided at one end of the hopper base facing the flipping direction, and its position is lower than the flipping mounting groove.

[0041] Optionally, the hopper base includes:

[0042] The base has two side plates, each suitable for being fixedly mounted on the transport device, and the top of each side plate has the flip-mounting groove, the support groove and the limiting groove.

[0043] There are multiple intermediate step plates, each fixedly connected to one of the two base side plates at each end.

[0044] Optionally, the locking structure includes:

[0045] Locking hooks are suitable for rotatable mounting on transport devices;

[0046] The locking frame is fixedly installed on the hopper body;

[0047] When the locking hook rotates forward, it can hook onto the locking frame, restricting the hopper body to a horizontal state; when the locking hook rotates backward, it can move out of the locking frame, no longer restricting the hopper body through the locking frame.

[0048] The present invention also provides a transport device, including a frame, wheels and handles, wherein a material transport hopper structure is detachably mounted on the frame; the material transport hopper structure is the material transport hopper structure as described in any of the preceding claims.

[0049] The technical solution provided by this invention has the following advantages:

[0050] 1. The material transport silo structure of the present invention includes a silo body, a silo base, a tilting frame, and a locking structure; the silo base is suitable for fixed installation on a transport device, the silo body is rotatably and flip-foldably installed on the silo base via the tilting frame, and the locking structure is used to lock the silo body in a horizontal state; the core of the present invention is that when the silo body is in a horizontal state and a first inclined state, the center of gravity is between the rotating structure and the tilting structure; when the silo body is in a second inclined state, the center of gravity of the silo body is outside the tilting structure.

[0051] In the initial state, the material transport hopper structure of the present invention is locked to the hopper base by a locking structure, and the hopper body is in a horizontal state. At this time, materials can be loaded into the hopper body. Since the materials are generally non-fixed in shape, the front-to-back position of the center of gravity can be considered to remain basically unchanged or only change slightly after loading the materials. After the hopper body loaded with materials is transported to the destination by the transport device, the locking structure only needs to be unlocked. Under the action of the gravity of the hopper body and the materials themselves, the hopper body can automatically flip from the horizontal state to the first tilted state. At this time, the center of gravity is still between the rotating structure and the flipping structure, but closer to the flipping structure. When an external force is used to push the hopper body to flip at this time, since the center of gravity is closer to the flipping structure, less force is needed when flipping, and the labor intensity is lower.

[0052] 2. The material transport hopper structure of the present invention includes a hopper base comprising a flip-mounting groove and a support groove. The flip-mounting groove is used for the flipping frame to be flipped and installed. The support groove is located on the side of the flip-mounting groove away from the flipping direction, and the support surface height of the support groove is higher than the support surface height of the flip-mounting groove. When the flipping frame is in the first flipping state, the support groove and the flip-mounting groove are used to support the flipping frame.

[0053] 3. The material transport silo structure of the present invention includes a tilting frame comprising a tilting side plate, a tilting shaft, a tilting through hole, and a tilting cylinder. The two ends of the tilting shaft are respectively fixedly connected to two tilting side plates. The tilting cylinder is installed on one side of the two tilting side plates with the tilting through hole and is coaxially arranged therewith. When the silo body automatically tilts from a horizontal state to a first tilted state, it is achieved by rotating through the rotating shaft of the tilting cylinder. After the silo body tilts to the first tilted state, the bottom surface of the silo body contacts the top surface of the tilting frame of the tilting side plate. With the connection between the rotating shaft and the tilting cylinder, when an external force is applied to push the silo body, it can push the silo body and the tilting frame to rotate together around the tilting shaft, thereby pushing the silo body to a second tilted state suitable for unloading.

[0067] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0068] Example 1

[0069] This embodiment provides a material transport silo structure, such as Figure 1-5 As shown, it includes: 1 hopper body, 2 hopper base, 3 tilting frame and locking structure.

[0070] Wherein: the hopper body 1 has a hopper bottom surface 11 and two parallel and opposite hopper side plates 12 disposed below both sides of the hopper bottom surface 11; the hopper base 2 is adapted to be fixedly installed on a transport device and is adapted to support the hopper body 1; the tilting frame 3 is rotatably installed on the hopper base 2 through a tilting structure and is rotatably connected to the two hopper side plates 12 through a rotating structure; the tilting frame 3 has a flat tilting frame top surface 31; after the tilting frame 3 is installed on the hopper base 2, it has a first tilting state with a first tilting angle and a second tilting state with a second tilting angle; the second tilting angle is greater than the first tilting angle; the... The hopper body 1 has a horizontal state supported by the hopper base 2, a first tilted state supported by the tilting frame 3 in a first tilted state, and a second tilted state supported by the tilting frame 3 in a second tilted state; when the hopper body 1 is in the horizontal state and the first tilted state, the center of gravity of the hopper body 1 is between the rotating structure and the tilting structure; when the hopper body 1 is in the second tilted state, the center of gravity of the hopper body 1 is outside the tilting structure; the locking structure has a locking state for locking the hopper body 1 in the horizontal state and an unlocking state for not locking the hopper body 1.

[0071] In the initial state, the hopper body 1 is locked to the hopper base 2 by the locking structure, and the hopper body 1 is in a horizontal state. After the locking structure is unlocked, the hopper body 1 automatically rotates to the first tilted state through the rotating structure under its own gravity. At this time, the bottom surface 11 of the hopper body 1 contacts the top surface 31 of the tilting frame 3. Under the action of external force, the hopper body 1 and the tilting frame 3 rotate around the tilting structure at the same time, thereby flipping the hopper body 1 from the first tilted state to the second tilted state.

[0072] In the initial state of the material transport hopper structure of this embodiment, the hopper body 1 is locked to the hopper base 2 by the locking structure, and the hopper body 1 is in a horizontal state. At this time, materials can be loaded into the hopper body 1. Since the materials are generally without a fixed shape, after loading the materials, it can be assumed that the front and rear positions of the center of gravity remain basically unchanged or only change slightly. After the hopper body 1 loaded with materials is transported to the destination by the transport device, the locking structure only needs to be unlocked. Under the action of the gravity of the hopper body 1 and the materials themselves, the hopper body 1 can automatically flip from the horizontal state to the first tilted state. At this time, the center of gravity is still between the rotating structure and the flipping structure, but closer to the flipping structure. When the hopper body is then pushed to flip by external force, since the center of gravity is closer to the flipping structure, less force is needed when flipping, and the labor intensity is lower.

[0073] In this embodiment, as Figure 2 and Figure 5 As shown, the hopper base 2 includes a flip-mounting groove 21 and a support groove 22; wherein: the flip-mounting groove 21 is used for the flipping frame 3 to be flipped and mounted; the support groove 22 is located on the side of the flip-mounting groove 21 away from the flipping direction, and is used together with the flip-mounting groove 21 to support the flipping frame 3 in the first flipped state; the support surface of the support groove 22 is higher than the support surface of the flip-mounting groove 21. When the flipping frame is in the first flipped state, the support groove and the flip-mounting groove are used to support the flipping frame.

[0074] like Figure 2 As shown, the flipping frame 3 includes: flipping side plates 32, flipping shafts 33, flipping through holes 34, and flipping cylinders 35; wherein, there are two flipping side plates 32, which are arranged opposite to each other; the two ends of the flipping shaft 33 are respectively fixedly connected to the two flipping side plates 32, and are rotatably mounted on the flipping mounting groove 21; there are two flipping through holes 34, which are respectively opened opposite to each other at the ends of the two flipping side plates 32 away from the flipping direction; the two ends of the flipping cylinder 35 are respectively fixedly connected to the two flipping side plates 32 with flipping through holes 34, and the central axis of the flipping cylinder 35 coincides with the central axis of the flipping through hole 34; and it is movably supported inside the support groove 22.

[0075] like Figure 3 and Figure 5 As shown, the flipping structure also includes a gate-shaped mounting plate 4, a first mounting hole 42, a second mounting hole 43, and mounting bolts 44; wherein, an inverted U-shaped groove 41 is formed in the middle of the gate-shaped mounting plate 4; there are two first mounting holes 42, which are respectively opened on both sides of the inverted U-shaped groove 41; there are two second mounting holes 43, which are respectively opened on both sides of the flipping mounting groove 21; after the mounting bolts 44 pass through the first mounting holes 42 and the second mounting holes 43, the gate-shaped mounting plate 4 is fixedly installed on the hopper base 2, and the flipping shaft 33 is rotatably restricted to be installed between the flipping mounting groove 21 and the inverted U-shaped groove 41.

[0076] like Figure 2 and Figure 4 As shown, in this embodiment, the rotating structure includes a rotating shaft 51 and rotating holes 52; wherein, there are two rotating holes 52, which are respectively opened opposite to each other on the side plate 12 of the hopper; the rotating shaft 51 passes through the tilting cylinder 35 and extends outward from the two rotating holes 52 for a certain length.

[0077] like Figure 4 and Figure 6-8 As shown, it also includes a baffle 53, a limiting hole 54, and a limiting clip 55; wherein, the baffle 53 is sleeved on the part of the rotating shaft 51 that extends out of the rotating hole 52; the limiting hole 54 is formed on the part of the rotating shaft 51 that extends out of the baffle 53; the limiting clip 55 is inserted into the limiting hole 54 to prevent the baffle 53 from slipping off.

[0078] like Figure 2 and Figure 5 As shown, it also includes a limiting structure for limiting the flipping frame 3 in the second flipping state; the limiting structure includes a limiting rod 36 and a limiting groove 23; wherein, the two ends of the limiting rod 36 are respectively fixedly connected to the ends of the two flipping side plates 32 opposite to the flipping cylinder 35; the limiting groove 23 is provided at the end of the hopper base 2 facing the flipping direction, and the position is lower than the flipping mounting groove 21.

[0079] like Figure 5 As shown, the hopper base 2 includes a base side plate 24 and a middle step plate 25; wherein, there are two base side plates 24, which are respectively adapted to be fixedly installed on the transport device, and the top ends are provided with the flip installation groove 21, the support groove 22 and the limiting groove 23; there are multiple middle step plates 25, and both ends are fixedly connected to the two base side plates 24 respectively.

[0080] like Figure 7As shown, the locking structure includes a locking hook 6 and a locking frame 13; wherein, the locking hook 6 is adapted to be rotatably mounted on the transport device; the locking frame 13 is fixedly disposed on the hopper body 1; when the locking hook 6 rotates forward, it can hook onto the locking frame 13 and restrict the hopper body 1 to a horizontal state; when the locking hook 6 rotates backward, it can move out of the locking frame 13 and no longer restrict the hopper body 1 through the locking frame 13.

[0081] The method of using the material transport silo structure in this embodiment is as follows:

[0082] Before transporting materials, the hopper body 1 is locked in a horizontal position by a locking structure, at which point materials can be loaded into the hopper body 1.

[0083] After filling, the material transport silo structure of this embodiment is transported to the target location, and then the silo body 1 is unlocked by the locking structure; the silo body 1 automatically rotates around the rotating shaft 51 under the action of gravity, rotating from a horizontal state to a first inclined state; after rotating to the first inclined state, the bottom surface of the silo body 1 contacts the top surface 31 of the tilting frame 3; at this time, the tilting shaft 33 of the tilting frame 3 is located in the tilting mounting groove 21, and the tilting cylinder 35 is located in the support groove 22;

[0084] When it is necessary to continue to rotate the hopper body 1 until all the material is poured out, push the hopper body 1 and the rotating frame 3 to rotate around the rotating shaft 33 until the limit rod 36 on the rotating frame 3 enters the limit groove 23, and the material dumping is completed.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
