For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0025] Please refer to the attached Figure 1 To the attached Figure 2 The utility model describes a bulk material loading and unloading auxiliary device for a forklift.

[0026] like Figure 1 As shown, the forklift bulk material loading and unloading auxiliary device of the present invention includes a bucket 1 and a hydraulic cylinder 2. One end of the hydraulic cylinder 2 is connected to the bucket 1. The bucket 1 is connected to a first fork sleeve 3 and a second fork sleeve 4 via a pin shaft. A fixed plate 5 is connected between the first fork sleeve 3 and the second fork sleeve 4. The end of the hydraulic cylinder 2 away from the bucket 1 is connected to the fixed plate 5 to drive the bucket 1 to tilt forward or backward. The ends of the first fork sleeve 3 and the second fork sleeve 4 away from the bucket 1 are respectively mounted on the forks of the forklift to make the bucket 1 rise or fall with the forklift. By mounting the first fork sleeve 3 and the second fork sleeve 4 on the forklift's forks, and realizing the rotation of the bucket 1 connected to the first fork sleeve 3 and the second fork sleeve 4 via a pin shaft, the bucket 1 is connected to the hydraulic cylinder 2. The hydraulic cylinder 2 drives the bucket 1 to tilt forward or backward to realize the bucket 1 shoveling and unloading. The forks drive the bucket 1 to achieve vertical lifting. This application is based on a forklift and adds a detachable loading and unloading auxiliary device to realize loading and unloading of bulk materials. It is flexible and simple and convenient to install with the forklift, realizing the multi-purpose and multi-functionality of the forklift. It not only improves production safety, but also significantly reduces labor, greatly reduces labor intensity, improves operating efficiency, and has very significant economic benefits.

[0027] Further, if Figure 1 and Figure 2As shown, the bucket 1 is provided with a first pin 6 and a second pin 7 at intervals, and the first fork sleeve 3 and the second fork sleeve 4 are connected to the first pin 6 and the second pin 7 respectively; a first rotation point 8 is welded at one end of the bucket 1 away from the first pin 6 and the second pin 7, and the first rotation point 8 is connected to the protruding end of the hydraulic cylinder 2 to drive the bucket 1 to tilt forward or backward; a support arm 10 is welded between the first fork sleeve 3 and the second fork sleeve 4, and the support arm 10 is welded on the side close to the bucket 1.

[0028] In this embodiment, preferably, the first pin 6 and the second pin 7 have the same shape and size, the first pin 6 and the second pin 7 are respectively fixed on the bucket 1, and the first pin 6 and the second pin 7 are located on the same horizontal line, the first fork sleeve 3 is rotatably connected to the first pin 6, and the second fork sleeve 4 is rotatably connected to the second pin 7, so that the bucket 1 rotates around the first fork sleeve 3 and the second fork sleeve 4.

[0029] Preferably, the forklift has a double-fork structure. The load capacity at 1.5 meters from the top of the forklift fork is 5.833 tons, and the bucket design volume is approximately 0.8m³, which is far lower than the maximum load capacity of the fork, ensuring maximum operational safety. The bucket has a unique shape and the loading center is backward, which is safer for the forklift fork load form and prevents bulk cargo from tipping forward and spilling during operation.

[0030] A first rotation point 8 is vertically welded to one end of the bucket 1 away from the first pin 6 and the second pin 7. The extended end of the hydraulic cylinder 2 is hinged to the first rotation point 8. The extended end drives the bucket 1 to rotate around the first fork sleeve 3 and the second fork sleeve 4, thereby realizing the forward or backward tilt of the bucket 1.

[0031] Preferably, the forklift has a total of four hydraulic oil circuits, three of which are in the front mast attachment of the forklift, one of which controls the lifting of the fork, one controls the tilting of the mast, and one controls the forklift accessories, that is, the left and right fork movement function of the fork. In order to retain the basic functions of the forklift during operation, that is, the lifting and tilting functions of the fork, when the bulk material loading and unloading auxiliary device is used in conjunction with the forklift, only the forklift accessories hydraulic oil circuit is idle. Therefore, it is the best choice to connect the hydraulic pipe that controls the bucket to the forklift accessories hydraulic oil circuit.

[0032] Preferably, the support arm 10 is vertically welded between the first fork sleeve 3 and the second fork sleeve 4 to provide sufficient support force for the bucket 1 during loading and unloading.

[0033] Further, if Figure 1As shown, a fixing plate 5 is welded to the end of the first fork sleeve 3 and the second fork sleeve 4 away from the bucket 1, an extension plate 11 is welded to the fixing plate 5, the extension plate 11 is connected to the second rotation point 9, and the end of the hydraulic cylinder 2 away from the first rotation point 8 is connected to the second rotation point 9; the lower surfaces of the first fork sleeve 3 and the second fork sleeve 4 gradually tilt upward along the direction from the fixing plate 5 to the bucket 1; connecting ports 12 are provided at intervals on the hydraulic cylinder 2, and a hydraulic cylinder hose is connected to the connecting port 12, and the hydraulic hose is connected to the hydraulic pipe of the forklift attachment to allow the protruding end of the hydraulic cylinder 2 to be extended or retracted.

[0034] In this embodiment, preferably, the first fork sleeve 3 and the second fork sleeve 4 are provided with a fixed plate 5 welded at one end of the opening, the fixed plate 5 is vertically welded between the first fork sleeve 3 and the second fork sleeve 4, an extension plate 11 is welded on the fixed plate 5, and a second rotation point 9 is vertically welded on the extension plate 11. The hydraulic cylinder 2 is hinged on the second rotation point 9, so that the length of the extended end of the hydraulic cylinder 2 changes, thereby realizing the change of the forward or backward angle of the bucket.

[0035] Preferably, the working pressure of the forklift hydraulic system is 20Mpa, but the overflow setting pressure of the accessories is 14Mpa. Then the pressure rating of the selected hydraulic cylinder 2 and oil pipes and other components must be greater than 14Mpa to ensure safe operation.

[0036] The first fork sleeve 3 and the second fork sleeve 4 are respectively mounted on the forks of the forklift. Preferably, the lower surfaces of the first fork sleeve 3 and the second fork sleeve 4 are gradually inclined upward along the direction from the fixed plate 5 to the bucket 1, so that the first fork sleeve 3 and the second fork sleeve 4 match the shape of the fork.

[0037] The attachment hydraulic pipe is connected to a hydraulic hose, which is connected to the hydraulic cylinder 2 to achieve control of the extended end of the hydraulic oil cylinder 2.

[0038] Further, if Figure 1 As shown, the attachment hydraulic pipe is provided with a tee or valve, and the quick connector of the hydraulic hose is connected to the tee or valve of the attachment hydraulic pipe; the bucket 1 is provided with a first pin shaft 6 and a second pin shaft 7, one side of which is a rectangular plate, and the bucket 1 rotates along the first pin shaft 6 and the second pin shaft 7 so that the bucket 1 abuts against the first fork sleeve 3 and the second fork sleeve 4; the bucket 1 is arranged in a trapezoidal shape as a whole.

[0039] In this embodiment, preferably, a tee and a valve are installed on the forklift attachment oil circuit near the fork of the forklift hydraulic system, which not only facilitates the conversion of the oil circuit, but also facilitates the installation and connection of the bulk hopper cylinder, which is efficient and convenient.

[0040] Preferably, the bucket 1 is provided with a first pin 6 and a second pin 7 on one side of which is a rectangular plate. When the bucket 1 rotates around the first pin 6 and the second pin 7, the bucket 1 can abut against the first fork sleeve 3 and the second fork sleeve 4. The bucket 1 is designed as an irregular trapezoid as a whole, which greatly improves the working efficiency.

[0041] The working principle of the forklift bulk material loading and unloading auxiliary device in the utility model is as follows:

[0042] First, adjust the distance between the fork and the first fork sleeve 3 and the second fork sleeve 4 so that the fork is inserted into the first fork sleeve 3 and the second fork sleeve 4, and lower the fork to the bottom surface of the forklift, turn off the engine and stop. With the engine off, move the operating lever up and down to release the hydraulic pipeline of the attachment to a depressurized state;

[0043] Then, connect the hydraulic cylinder hose connected to the hydraulic cylinder 2 to the attachment hydraulic pipe tee. After the connection, close the attachment hydraulic pipe ball valve, open the attachment hydraulic pipe tee ball valve, and operate the forklift. At this time, the forward and backward tilt of the bucket is controlled by the attachment operating handle. Other forklift functions remain unchanged, thus realizing the bulk material loading function;

[0044] Then, when loading bulk materials, in order to achieve the best loading efficiency, the bucket 1 should be moved forward with its front tilt surface parallel to the ground. According to the loading status, the attachment handle should be operated to tilt the bucket 1 backward to a horizontal state for reverse transportation. According to the loading height requirement, the mast fork can be operated to reach a certain height, and then the bucket 1 can be tilted forward to unload, and this cycle can be repeated.

[0045] Finally, after the work is completed, lower the forks to the ground. When the forklift is turned off, move the operating lever up and down to release the attachment hydraulic pipeline to a pressure-free state, then close the attachment hydraulic pipe three-way ball valve, open the attachment hydraulic pipe ball valve, unplug the hydraulic cylinder hose quick connector, start the forklift, and pull out the forks in the first fork sleeve 3 and the second fork sleeve 4.

[0046] Based on a forklift bulk material loading and unloading auxiliary device, the present invention sets a first fork sleeve 3 and a second fork sleeve 4 on the fork of the forklift, and realizes the rotation connection of the bucket 1 to the first fork sleeve 3 and the second fork sleeve 4 through the first pin shaft 6 and the second pin shaft 7. The bucket 1 is connected to a hydraulic cylinder 2, which drives the bucket 1 to tilt forward or backward to realize the bucket 1 shoveling and unloading, and the fork drives the bucket 1 to realize vertical lifting. The present application is based on a forklift, and adds a detachable loading and unloading auxiliary device to realize the loading and unloading of bulk materials. The installation and coordination with the forklift are flexible, simple and convenient, and the forklift is realized. It realizes the multi-purpose and multi-functionality of the forklift, which not only improves production safety, but also significantly reduces labor and labor intensity, improves work efficiency, and has very significant economic benefits.
