Technical Field
[0001] This utility model relates to the field of tipping machine technology, specifically a tipping machine with automatic grain unloading function. Background Technology
[0002] When unloading grain, grain trucks are too long to be quickly unloaded by their own unloading devices. Therefore, a tipping unloading device is needed to tilt the entire grain truck for easier unloading. However, existing tipping unloading devices can only limit the wheels of the truck. For example, a rear-tipping hydraulic tipping grain truck unloading device with publication number CN216736618U has fixed blocks symmetrically installed at one end of the pit, and a rotating shaft base is installed on the fixed blocks. One end of the tipping platform is hinged to the rotating shaft base through a rotating shaft. Baffles are symmetrically installed on both sides of the upper surface of the tipping platform. A lifting wheel stop is installed on the side of the tipping platform near the fixed block. Once the wheel stop fails, the vehicle loses its limit, resulting in a low safety factor.
[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a flipper with automatic grain unloading function, comprising a trough base, a connecting plate hinge on the trough base, a flipper mounted on the connecting plate hinge, a first hydraulic cylinder hinged between the inner bottom surface of the trough base and the lower wall surface of the flipper, a trapezoidal extension plate near the connecting plate hinge on the flipper, guide side plates symmetrically arranged on the upper wall surface of the trapezoidal extension plate, wheel stops on the flipper near the trapezoidal extension plate, and two protective structures symmetrically arranged on the flipper on one side of the wheel stops.
[0005] The two protective structures include a second hydraulic cylinder, which is mounted on the upper wall of the flap. The telescopic end of the second hydraulic cylinder is equipped with a side mounting seat, which is arranged along the length of the flap. A third hydraulic cylinder is fixedly inserted into the side mounting seat. A pressure sensor is mounted on the telescopic end of the third hydraulic cylinder. A clamping plate is mounted on the pressure sensor. A T-shaped locking block is mounted on the clamping plate. A follow-up fitting component is provided on the T-shaped locking block.
[0006] The follow-up bonding component includes a bonding plate, on which a T-shaped groove is formed that matches the T-shaped card block. The T-shaped groove is movably fitted onto the T-shaped card block, and multiple springs are installed between the T-shaped groove and the T-shaped card block.
[0007] Preferably, the wheel stop includes a fixed seat, which is installed on the upper wall of the flap along the width direction of the flap. A fourth hydraulic cylinder is installed on the inner bottom surface of the fixed seat. A tension sensor is installed on the telescopic end of the fourth hydraulic cylinder. A bending frame is installed on one end of the tension sensor. The bending frame is movably inserted into the fixed seat.
[0008] Preferably, the number of the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, and the fourth hydraulic cylinder is at least two.
[0009] Preferably, a first guide rod is movably inserted into the side mounting base, and the first guide rod is fixedly installed on the upper wall surface of the flip plate.

[0011] Preferably, one end of the bending frame is provided with an arc-shaped surface.
[0012] Beneficial effects
[0013] This utility model provides a tipper with automatic grain unloading function. Compared with the prior art, it has the following advantages: the rear wheels of the grain transport vehicle are fixed by the wheel stops to prevent the grain transport vehicle from rolling backward. Two protective structures limit and clamp the lateral movement of the grain transport vehicle to prevent it from moving laterally or even falling off the side of the tipper, thus improving the safety factor. It is suitable for use with beam transport vehicles of different widths. It also prevents the beam transport vehicle from slipping due to the failure of the wheel stops, thus improving the safety factor. When unloading grain, the first hydraulic cylinder gradually extends, and the grain falls from the rear of the grain transport vehicle onto the tipper. Under the action of gravity, it slides off the trapezoidal extension plate. The guide side plate is used to gather the grain at the rear of the trapezoidal extension plate to prevent the grain from falling off the side and to facilitate the collection of grain.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.
[0022] Please see Figure 1-5 In order to solve the problem that the existing tippler unloading device can only limit the wheels of the beam transport vehicle, and the vehicle loses its limit once the wheel stop fails, resulting in a low safety factor, this technical solution is designed. The detailed technical solution is as follows.
[0023] A flip-plate machine with automatic grain unloading function includes a trough base 1, a connecting plate hinge 2 on the trough base 1, a flip plate 3 installed on the connecting plate hinge 2, a first hydraulic cylinder 4 hinged between the inner bottom surface of the trough base 1 and the lower wall surface of the flip plate 3, a trapezoidal extension plate 5 on the flip plate 3 near the connecting plate hinge 2, a guide side plate 6 symmetrically arranged on the upper wall surface of the trapezoidal extension plate 5, a wheel stop on the flip plate 3 near the trapezoidal extension plate 5, and two protective structures symmetrically arranged on the flip plate 3 on one side of the wheel stop.
[0024] It should be noted that the trough seat 1 is embedded in the unloading area. The device is connected to the control system and the hydraulic system. When the first hydraulic cylinder 4 is retracted to the limit position, the flap 3 is fastened on the trough seat 1. At this time, the flap 3 is close to the horizontal plane of the unloading area. The grain truck reverses onto the flap 3 until the rear wheels of the grain truck contact the wheel chocks. The grain truck stops reversing and the parking brake of the grain truck is applied.
[0025] Specifically, the two protective structures include a second hydraulic cylinder 7, which is installed on the upper wall of the flap 3. The telescopic end of the second hydraulic cylinder 7 is equipped with a side mounting seat 8, which is set along the length of the flap 3. A third hydraulic cylinder 9 is fixedly inserted into the side mounting seat 8. A pressure sensor 10 is installed on the telescopic end of the third hydraulic cylinder 9. A clamping plate 11 is installed on the pressure sensor 10. A T-shaped clamping block 21 is installed on the clamping plate 11. A follow-up fitting component is provided on the T-shaped clamping block 21.
[0026] It should be noted that the wheel stops are used to secure the rear wheels of the grain truck, preventing it from rolling backward. The extension and retraction of the second hydraulic cylinder 7 adjusts the height of the side mounting seat 8, aligning the follow-up bonding component with the outer wall of the grain truck's cargo compartment. Then, the extension of the third hydraulic cylinder 9 stops when the pressure sensor 10 detects that the pressure has reached the set value. This means that the follow-up bonding component is clamped against the outer wall of the grain truck's cargo compartment, providing lateral restraint and preventing the grain truck from moving laterally or even falling off the side of the flap 3, thus improving safety. It can be used for beam transport vehicles of different widths, and also prevents the beam transport vehicle from slipping due to the failure of the wheel stop, thus improving the safety factor. When unloading grain, the first hydraulic cylinder 4 gradually extends, pushing the tipping plate 3 to rotate on the trough seat 1 through the connecting plate hinge 2. As a result, the grain transport vehicle tilts backward, and the grain falls from the rear of the grain transport vehicle onto the tipping plate 3. Under the action of gravity, it slides down from the trapezoidal extension plate 5. The guide side plate 6 is used to gather the grain at the rear of the trapezoidal extension plate 5 to prevent the grain from falling off the side and to facilitate the collection of grain. The staff can place containers or set up a space to hold grain at the rear of the trapezoidal extension plate 5.
[0027] Specifically, the follow-up bonding component includes a bonding plate 19, on which a T-shaped groove is provided that matches the T-shaped locking block 21. The T-shaped groove is movably fitted onto the T-shaped locking block 21, and multiple springs 20 are installed between the T-shaped groove and the T-shaped locking block 21.
[0028] It should be noted that, under the action of spring 20, T-shaped block 21 is located in the middle of T-shaped slide. Through the extension of the third hydraulic cylinder 9, the plate 19 can move up and down on T-shaped block 21 through the slide. Under the action of friction, the plate 19 adheres to the outer wall of the grain truck bed. As the unloading time increases, the amount of grain in the grain truck bed decreases, and the overall weight of the grain in the bed becomes lighter. Therefore, under the action of the grain truck suspension, the height of the grain truck bed will increase. The plate 19 then moves on T-shaped block 21 through T-shaped slide, which is suitable for changes in the height of the bed.
[0029] Specifically, the wheel stop includes a fixed seat 12, which is installed on the upper wall of the flap 3 along the width direction of the flap 3. A fourth hydraulic cylinder 13 is installed on the inner bottom surface of the fixed seat 12. A tension sensor 14 is installed on the telescopic end of the fourth hydraulic cylinder 13. A bending frame 15 is installed on one end of the tension sensor 14. The bending frame 15 is movably inserted into the fixed seat 12.
[0030] It should be noted that when the grain transport vehicle reverses until the rear wheels of the grain transport vehicle contact the fixed seat 12, the grain transport vehicle stops reversing. Then, the fourth hydraulic cylinder 13 retracts, causing the bending frame 15 to fit against the rear wheels of the beam transport vehicle. When the tension sensor detects that the pressure value reaches the set value, the fourth hydraulic cylinder 13 stops working, thus blocking the rear wheels of the beam transport vehicle. This method is suitable for use with wheels of different sizes. By using the bending frame 15 to block the rear wheels, compared to a vertical baffle, when the flip plate 3 is folded at a larger angle, the bending part of the bending frame 15 expands the blocking range for the rear wheels, preventing the rear wheels from falling off the blocking part and improving the safety factor.
[0031] The wheel chocks and protective structures can employ two hydraulic systems to prevent the failure of one of the hydraulic systems.
[0032] Preferably, the number of the first hydraulic cylinder 4, the second hydraulic cylinder 7, the third hydraulic cylinder 9 and the fourth hydraulic cylinder 13 is at least 2;
[0033] As a preferred and further option, a first guide rod 16 is movably inserted into the side mounting base 8. The first guide rod 16 is fixedly installed on the upper wall of the flap 3 to protect the telescopic end of the second hydraulic cylinder 7.
[0034] As a preferred and further option, a second guide rod 17 is movably inserted into the side mounting base 8, and the second guide rod 17 is fixedly installed on the clamping plate 11 to protect the telescopic end of the third hydraulic cylinder 9.
[0035] As a preferred and further option, one end of the bending frame 15 is provided with an arc-shaped surface 18 to prevent the bending frame 15 from scratching the truck wheels.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
