[0002] Log splitters are mainly used for processing wood, decomposing and cutting tree stumps, large tree branches, large round wood sections and relatively hard wood materials, and splitting them into multiple segments of required length and thickness according to usage. When traditional log splitters work, workers need to manually place the wood on the log splitter. Since the wood is relatively heavy, it takes a lot of physical effort to load the wood, and there are also safety hazards. To solve the above problems, some log splitters that are convenient for feeding have emerged on the market.

[0003] For example, the Chinese utility model patent "A log splitter with automatic feeding" with the patent publication number CN219311538U includes a bottom plate.

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will understand that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present invention.

[0027] It should be noted that: Similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0028] This embodiment mainly elaborates on the flap feeding mechanism of the log splitter, as follows:

[0029] As Figures 1 to 7 shown, the flap feeding mechanism of the log splitter includes a log splitter frame 1. A wood placement table 2 is provided on the log splitter frame 1. The wood placement table 2 is used to place the wood 10 to be split. A loading rack 3 is rotatably connected to one side of the wood placement table 2. The loading rack 3 is used to convey the wood 10 to the wood placement table 2. A telescopic pushing assembly 4 is provided on the log splitter frame 1. The pushing assembly 4 provides the power for conveying the wood 10 to the loading rack 3. The telescopic end of the pushing assembly 4 always abuts against the bottom surface of the loading rack 3. When the pushing assembly 4 expands and contracts, it can push the loading rack 3 to flip, lift the wood 10 on the loading rack 3 and make the wood 10 roll from the loading rack 3 to the wood placement table 2. A pressure sensor for detecting the pressure on the loading rack 3 is provided on the pushing assembly 4. The pressure sensor and the pushing assembly 4 are jointly connected to a controller. When the wood 10 is placed on the loading rack 3, the pressure sensor senses an increase in pressure and transmits a signal to the controller. The controller controls the telescopic end of the pushing component 8 to extend and push the loading rack 3 to flip upward to roll the wood 10 to the wood placement table 2; when the wood 10 is sent to the wood placement table 2, the pressure sensor senses a decrease in pressure and transmits a signal to the controller. The controller controls the telescopic end of the pushing component 8 to contract, and the loading rack 3 flips downward to return to contact with the ground. During the feeding process, there is no need for manual operation to make the telescopic end of the first hydraulic cylinder 41 extend or retract. The operation is simple and convenient, improving the feeding automation degree of the feeder.

[0030] As shown in Figure 4 , Figure 6 and Figure 8 shown, the pushing component 4 includes a first hydraulic cylinder 41 and an elastic roller assembly 43. The first hydraulic cylinder 41 is connected to the fuel tank 42 through an inlet pipe and an outlet pipe. The fuel tank 42 inputs oil into the first hydraulic cylinder 41 through the inlet pipe. When the telescopic end of the first hydraulic cylinder 41 extends, the oil in the first hydraulic cylinder 41 returns to the fuel tank 42 through the outlet pipe. When the telescopic end of the first hydraulic cylinder 41 contracts, the elastic roller assembly 43 is fixedly connected to the telescopic end of the first hydraulic cylinder 41, and the elastic roller assembly 43 can slide on the bottom of the loading rack 3. A pressure sensor is arranged on the elastic roller assembly 43.

[0031] Specifically, a fixed seat 5 is arranged on the wood splitting machine frame 1. The fixed seat 5 is located below the wood placing table 2. The first hydraulic cylinder 41 is fixed on the fixed seat 5. A support shaft 6 for supporting and guiding the elastic roller assembly 43 is slidably arranged on the fixed seat 5. One end of the support shaft 6 away from the fixed seat 5 is fixedly connected to the elastic roller assembly 43. Preferably, there are two support shafts 6, which are respectively arranged on both sides of the first hydraulic cylinder 41. The design of the support shaft 6 can reduce the supporting weight of the telescopic end of the first hydraulic cylinder 41, thereby avoiding deformation of the telescopic rod of the first hydraulic cylinder 41 due to excessive load on the telescopic end of the first hydraulic cylinder 41, and thus reducing the service life of the first hydraulic cylinder 41.

[0032] Specifically, the elastic roller assembly 43 includes a mounting seat 431, a plurality of compressible and resilient elastic members, and a plurality of rollers 432. The mounting seat 431 is fixedly connected to the telescopic end of the first hydraulic cylinder 41. There are support columns 435 on both sides of the mounting seat 431. The rollers 432 are rotatably arranged on the support columns 435. The support columns 435 are used to support the loading rack 3. An installation chamber 436 is arranged on the mounting seat 431 between the two support columns 435. A plurality of elastic members are arranged in the installation chamber 436. A connecting block 434 is fixedly arranged on the elastic member. A roller 432 is arranged between every two connecting blocks 434 through a wheel shaft 437. The pressure sensor is arranged on the elastic member. The elastic member is a gas spring 433 or a cylinder. When the elastic member is subjected to pressure, the pressure sensor will feedback the pressure signal to the controller, thereby controlling the first hydraulic cylinder 41 to intake oil, pushing and flipping the loading rack 3 to send the wood 10 to the wood placing table 2.

[0033] As shown in Figure 7 and Figure 8 shown, a chute 311 is arranged at the bottom of the loading rack 3. The number of chutes 311 is equal to the number of rollers 432, and the chutes 311 correspond to the rollers 432 one by one. Guide strip holes 312 are arranged on the two groove arms of the chute 311. The wheel shaft 437 extends into the guide strip holes 312 and can slide in the guide strip holes 312. The setting of the guide strip holes 312 has a guiding and limiting effect on the rollers 432, avoiding the rollers 432 from disengaging from the chute 311 during the sliding process.

[0034] Specifically, the cross-section of the loading rack 3 is L-shaped. On both sides of the end of the loading rack 3, there are hook bodies 313 facing the inside of the loading rack 3. The hook bodies 313 can limit the position of the wood 10 to prevent the wood 10 from falling off during the upward flipping process of the loading rack 3.

[0035] As Figure 1 , Figure 5 and Figure 7 shown, on one side of the wood placement table 2 away from the loading rack 3, there is a blocking block 7 arranged along the length direction of the wood placement table 2. On the blocking block 7, there are several spaced limiting vertical rods 71. The lower side of the limiting vertical rods 71 is a curved arc end facing the wood placement table 2. The arrangement of the blocking block 7 and the limiting vertical rods 71 has an intercepting effect on the wood 10, avoiding the wood 10 from slipping off the wood placement table 2 when the wood 10 slides from the loading rack 3 to the wood placement table 2 due to the large kinetic energy of the wood 10.

[0036] As Figure 1 shown, on one side of the log splitter frame 1, there is a pushing component 8, and on the other side, there is a splitting knife component 9 fixedly arranged. Moreover, the pushing component 8 and the splitting knife component 9 are respectively located on both sides of the wood placement table 2. The pushing component 8 is used to push the wood 10 on the wood placement table 2 towards the splitting knife component 9. The splitting knife component 9 is used to divide the wood 10 to reach the required size. The pushing component 8 includes a first hydraulic cylinder 41 and a push plate 82. The second hydraulic cylinder 81 is connected to the fuel tank 42 through an oil inlet pipe and an oil outlet pipe. The push plate 82 is fixedly connected to the telescopic end of the second hydraulic cylinder 81. The second hydraulic cylinder 81 is fixed to the log splitter frame 1 by screws. The splitting knife component 9 includes a splitting knife 91 and a connecting seat 92. The connecting seat 92 is fixed on the log splitter frame. The connecting seat 92 has a vertical mounting plate 93. The splitting knife 91 is fixedly connected to the mounting plate and the cutting edge of the splitting knife 91 is aligned with the push plate 82.
