[0029] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0030] See also Figures 1 to 4 As shown, according to an embodiment of the first aspect of the present application, a quick-change grass grabbing fork is provided, comprising: a grass grabbing fork 1, a fixing plate 2 and a mounting plate 3;

[0031] The fixing plate 2 is arranged on the grass grabbing fork 1, and a limiting member 4 and a connecting plate 5 are respectively arranged on the top and bottom of the fixing plate 2 away from the grass grabbing fork 1, the limiting member 4 is provided with a limiting groove, and the connecting plate 5 is provided with a mounting hole 6;

[0032] A mounting rod 7 is provided on the top of the mounting plate 3, and the mounting rod 7 is located in the limiting groove. A fixing seat 8 is provided on the mounting plate 3 and below the mounting rod 7, and a fixing member 9 is provided on the fixing seat 8, and the fixing member 9 is detachably arranged in the mounting hole 6;

[0033] The mounting plate 3 is provided with a connecting ear 26 , and the mounting plate 3 is hinged to the boom of the loader via the connecting ear 26 .

[0034] Specifically, the mounting plate 3 is mounted on the fixing plate 2, and the mounting rod 7 is located in the limiting groove of the limiting member 4. The limiting groove can limit the movement of the mounting rod 7. The number of fixing seats 8 matches the number and position of the connecting plate 5. The fixing member 9 is movably mounted on the fixing seat 8. The bottom of the fixing member 9 can penetrate into the mounting hole 6 of the connecting plate 5 through the fixing seat 8, thereby realizing the connection between the grass grabbing fork 1 and the loader. At this time, through the movement of the loader, the grass grabbing fork 1 can grab and transfer crops. Due to the different sizes of crops, when different crops need to be grabbed and the grass grabbing fork 1 of appropriate size needs to be replaced, the fixing member 9 can be pulled upward to make the bottom of the fixing member 9 detach from the mounting hole 6 of the connecting plate 5, and then the mounting rod 7 can be slid downward from the limiting groove to realize the replacement of the grass grabbing fork 1. The replacement is convenient, the replacement efficiency is effectively improved, the replacement time is shortened, and the work efficiency is improved.

[0035] Specifically, the limiting groove on the limiting member 4 is opened toward the bottom of the fixing plate 2, and the mounting rod 7 can be slid upward along the fixing plate 2 and installed in the limiting groove, which is convenient for installation. At the same time, the installed mounting rod 7 can be limited from the top and the front and rear sides, thereby improving the fixing performance of the mounting rod 7.

[0036] The fixing seat 8 comprises: a fixing horizontal plate 10 and a fixing vertical plate 11;

[0037] The fixed horizontal plate 10 is arranged on the mounting plate 3, the fixed vertical plate 11 is arranged on one side of the mounting plate 3, a sliding hole is opened on the fixed horizontal plate 10, the fixing member 9 is slidably set in the sliding hole, and a card slot is opened on the fixed vertical plate 11.

[0038] The card slot is a U-shaped structure.

[0039] Specifically, the fixed cross plate 10 is installed on the mounting plate 3, and a sliding hole for installing the fixing member 9 is opened on the fixed cross plate 10. The fixing member 9 can slide up and down in the sliding hole, and then enter or disengage from the mounting hole 6 of the connecting plate 5, so as to realize the stable connection and disassembly of the mounting plate 3 and the bottom of the fixing plate 2. During the disassembly process, it is only necessary to pull up the fixing member 9 to disengage from the mounting hole. Compared with the need to disassemble the screw, its disassembly is more convenient and labor-saving.

[0040] The fixed transverse plate 10 and the fixed vertical plate 11 are respectively mounted on the mounting plate 3 , and the fixed transverse plate 10 is connected to the fixed vertical plate 11 to improve the stability of the fixing seat 8 .

[0041] The fixing member 9 includes: a rod body 12 and a limiting plate 13;

[0042] The rod body 12 is disposed in the sliding hole, the limiting plate 13 is disposed on the rod body 12 and located on the fixed transverse plate 10 , and the diameter of the limiting plate 13 is greater than the diameter of the sliding hole.

[0043] Specifically, the fixing member 9 includes a rod body 12 and a limit plate 13. The limit plate 13 is installed above the rod body 12. The diameter of the limit plate 13 is larger than the diameter of the sliding hole. The rod body 12 can move up and down in the sliding hole of the fixed horizontal plate 10. The limit plate 13 is located at the top of the fixed horizontal plate 10 and can limit the rod body 12 to prevent the rod body 12 from falling from the sliding hole.

[0044] The fixing member 9 further includes a handle 14 , and the handle 14 passes through the slot and is connected to the limiting plate 13 .

[0045] Specifically, the handle 14 is installed horizontally on the limit plate 13 through the slot, and the handle 14 is used to facilitate the movement of the rod body 12. The slot is an inverted U-shaped structure, which is convenient for clamping and fixing the handle 14, so as to limit and fix the bottom of the rod body 12 entering into the mounting hole and sliding out of the mounting hole for limit and fixation.

[0046] A protective cover 15 is disposed on the fixing plate 2 and located on one side of the limiting member 4 , and the opposite side and the bottom of the protective cover 15 are open structures.

[0047] Specifically, there are two protective covers 15 installed on the fixed plate 2. After the mounting rod 7 is placed in the limiting groove, the two ends of the mounting rod 7 are located in the protective covers 15. The protective covers 15 can protect the two ends of the mounting rod 7, reduce the collision of the mounting rod 7 during use, cause its deformation, affect the subsequent disassembly, and also reduce the probability of the mounting rod 7 detaching.

[0048] The number of the limiting members 4 and the connecting plates 5 is two, and the limiting members 4 and the connecting plates 5 are symmetrically arranged on the fixing plate 2 .

[0049] Specifically, there are two limit members 4 symmetrically installed at the top of the fixing plate 2 away from the grass grabbing fork 1, and there are two connecting plates 5 symmetrically installed at the bottom of the fixing plate 2 away from the grass grabbing fork 1. The two limit plates 13 are arranged to limit the mounting rod 7 from both sides, thereby limiting the top of the mounting plate after installation; the two connecting plates 5 are arranged to achieve a more stable connection with the fixing member 9, thereby achieving fixation of the mounting plate 3 and the bottom of the fixing plate 2, and improving the overall connection stability of the mounting plate 3 and the fixing plate 2 after installation.

[0050] The grass grabbing fork 1 comprises: a lower fork body 16, a connecting beam 17, a connecting arm 18, a first pin shaft 19, a second pin shaft 20, a third pin shaft 21, a cylinder 22, a fixing beam 23 and an upper fork body 24;

[0051] A connecting beam 17 is arranged between the lower fork bodies 16, the fixing plate 2 is fixedly connected to the connecting beam 17, a first pin shaft 19 is arranged between the middle part of the connecting arm 18 and the lower fork body 16, a groove is opened on the first end of the connecting arm 18, a second pin shaft 20 is arranged in the groove, a third pin shaft 21 is arranged in the middle part of the lower fork body 16, the oil cylinder 22 is arranged between the second pin shaft 20 and the third pin shaft 21, a fixing beam 23 is arranged between the connecting arms 18, and an upper fork body 24 is arranged on the fixing beam 23.

[0052] The grass grabbing fork 1 further includes a fork rod 25 , and a fork rod 25 is disposed in the middle of the connecting beam 17 .

[0053] Specifically, the lower fork body 16 is rotatably connected to the middle part of the connecting arm 18 through the first pin shaft 19. When the oil cylinder 22 is extended and retracted to drive the lower fork body 16 and the first end of the connecting arm 18 to move, it can drive the upper fork body 24 and the lower fork body 16 to move toward or in the opposite direction, thereby achieving the bite and release of the crops and facilitating the recovery of the crops.
