Description

Technical Field

[0001] The utility model relates to the technical field of peanut harvesters, in particular to an anti-falling structure of a peanut harvester. Background Art

[0002] Peanut harvester refers to a crop harvesting machine that completes operations such as digging, separating soil, laying strips, picking, picking, and cleaning during the peanut harvesting process. In actual production, it is necessary to select appropriate machines according to one's own needs and the characteristics of the peanut harvester, which can complete peanut digging, soil removal, picking, cleaning, and fruit collection operations at one time, with fast transfer speed and safe and reliable use.

[0003] When harvesting peanuts, a peanut digger can be used to first dig up the peanut plants in the soil and place them upside down in the corresponding ridges. After the peanut plants are dug up, a peanut picking harvester is used to separate the branches and fruits of the peanut plants. However, when the peanut plants are picked up by the drum-type peanut picking harvester, some peanut fruits and plant rhizomes are easily fallen off, so it is necessary to arrange additional manual labor to pick them up.

[0004] Therefore, we propose an anti-falling structure for a peanut harvester. Summary of the invention

[0005] The purpose of the utility model is to provide an anti-falling structure for a peanut harvester to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-falling structure of a peanut harvester, comprising: a mounting frame, the mounting frame is used to be connected to the entrance of the peanut harvester, a conveying frame for conveying peanut plants is fixedly installed on the outer side of the mounting frame, a lifting assembly for picking up peanut plants is arranged on the mounting frame, and a transmission assembly for transmitting power of the lifting assembly is arranged between the lifting assembly and the mounting frame.

[0007] Preferably, the upper transport component includes a conveying grid slidably connected to a mounting frame, a plurality of baffles of the same size are fixedly mounted on the conveying grid, and a plurality of hooks of the same size are fixedly connected to the baffles.

[0008] Preferably, both side vertical plates of the mounting frame are provided with sliding tracks matching with the conveying grid, and the opposite surfaces of both side vertical plates of the mounting frame are arc-shaped.

[0009] Preferably, a plurality of vertical rods of the same size are fixedly mounted on one side of the conveying frame opposite to the conveying grid.

[0010] Preferably, the transmission assembly includes a driven roller one rotatably connected to the mounting frame, a driven roller three rotatably mounted on the mounting frame is provided on one side of the driven roller one, and a driven roller two rotatably connected to the mounting frame is provided between the driven roller three and the driven roller one.

[0011] Preferably, gears are fixedly mounted on one end of the driven roller 1, both ends of the driven roller 2 and both ends of the driven roller 3, and a transmission chain is connected between the two gears on the same side.

[0012] Preferably, the gear at the other end of the driven roller three is connected to the power part of the peanut harvester through a transmission chain.

[0013] The utility model has at least the following beneficial effects:

[0014] In the utility model, when the user uses the anti-falling structure of the peanut harvester to pick peanuts, the mounting frame of the anti-falling structure can be connected to the main body of the peanut harvester. After the connection is completed, the gear at the other end of the driven roller three on the transmission assembly is connected to the power part of the main body of the peanut harvester through a transmission chain. After the connection is completed, when the user starts the peanut harvester, the driven roller three is rotated. When the driven roller three rotates, the driven roller one and the driven roller two are driven to rotate synchronously. When the driven roller one, the driven roller two and the driven roller three rotate, the conveying grille starts to rotate effectively. When the conveying grille rotates, the placement height of the conveying grille can be adjusted by the mechanical arm of the main body of the peanut harvester. When the adjustment is completed, the height of the conveying grille is adjusted. The hook starts to rotate, thereby picking up the peanut plants on the ridge. When the peanut plants are picked up to the top of the conveying grid, the peanut plants fall onto the conveyor frame under the action of gravity and are transmitted to the separation device of the main body of the peanut harvester for branch and fruit separation. Because the peanut excavator has loosened the soil on the ridge when digging the peanut plants, and then picked up by the hook and blocked by the baffle, the integrity of the peanut plants is guaranteed when picking up, thereby effectively reducing the falling of peanut shells. This effectively reduces the situation in the past where some peanut fruits and plant rhizomes are easily detached when the peanut plants are picked up by the drum type of the peanut picking harvester, thereby requiring additional manual picking. This effectively reduces the fruit drop rate during peanut harvesting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0024] See also Figure 1-5The utility model provides a technical solution: an anti-falling structure of a peanut harvester, comprising: a mounting frame 1, the mounting frame 1 is used to be connected to the entrance of the peanut harvester, a conveying frame 2 for conveying peanut plants is fixedly installed on the outer side of the mounting frame 1, an upper transport component 3 for picking up peanut plants is arranged on the mounting frame 1, and a transmission component 4 for transmitting power to the upper transport component 3 is arranged between the upper transport component 3 and the mounting frame 1. When a user uses the anti-falling structure of the peanut harvester to pick up peanuts, the anti-falling structure can be The mounting frame 1 of the shedding structure is connected to the main body of the peanut harvester. After the connection is completed, the gear 44 at the other end of the driven roller 3 43 on the transmission assembly 4 is connected to the power part of the main body of the peanut harvester through the transmission chain 45. After the connection is completed, when the user starts the peanut harvester, the driven roller 3 43 is rotated. When the driven roller 3 43 rotates, the driven roller 1 41 and the driven roller 2 42 are driven to rotate synchronously. When the driven roller 1 41, the driven roller 2 42 and the driven roller 3 43 rotate, The conveying grid 31 starts to rotate effectively. When the conveying grid 31 rotates, the placement height of the conveying grid 31 can be adjusted by the mechanical arm of the main body of the peanut harvester. When the adjustment is completed, the hook 33 on the conveying grid 31 starts to rotate, so as to pick up the peanut plants on the ridge. When the peanut plants are picked up to the top of the conveying grid 31, the peanut plants are dropped onto the conveying frame 2 under the action of gravity and transmitted to the separation device of the main body of the peanut harvester for branch and fruit separation. Because the peanut excavator has loosened the ridge soil when digging the peanut plants, and then picked up by the hook 33, combined with the blocking of the baffle 32, the integrity of the peanut plants is guaranteed when picking up the peanut plants, thereby effectively reducing the falling of peanut shells, which effectively reduces the situation in the past that some peanut fruits and plant rhizomes are easily detached when the peanut plants are picked up by the drum type of the peanut picking harvester, so that it is necessary to arrange manual picking, thereby effectively reducing the fruit drop rate during peanut harvesting.

[0025] The upper transport component 3 includes a conveying grid 31 slidably connected to the mounting frame 1, a plurality of baffles 32 of the same size are fixedly mounted on the conveying grid 31, a plurality of hooks 33 of the same size are fixedly connected to the baffles 32, wherein the hooks 33 are provided in multiple groups, combined with the baffles 32, and the baffles 32 adopt a U-shaped design, with a low middle part and two ends inclined inwardly, so that when the peanut harvester is in use, it forms an operation mode of an excavator digging head, thereby picking up the peanut plant as a whole together with part of the ground soil, and then through the holes of the conveying grid 31 combined with the vibration of the peanut harvester when in use, the soil is discharged, thus ensuring that the plants are picked up in a complete state.

[0026] The vertical plates on both sides of the mounting frame 1 are provided with sliding rails that cooperate with the conveying grille 31. The opposite surfaces of the vertical plates on both sides of the mounting frame 1 are designed in an arc shape. The sliding rails ensure the positioning of the conveying grille 31, thereby reducing the misalignment of the conveying grille 31 and causing many problems when the peanut harvester is used. The mounting frame 1 adopts an arc design, and the end of the mounting frame 1 adopts an outward-opening figure-eight design, so that the branches and leaves of the peanut plants can be effectively deformed and attached to the edges when picking up, thereby reducing the impact on the picking of the peanut plants.

[0027] A plurality of vertical rods of the same size are fixedly mounted on one side of the conveying frame 2 relative to the conveying grid 31, wherein the vertical rods are made of rubber material with high toughness, so that the residues on the hooks 33 can be effectively cleaned, thereby ensuring the cleanliness of the peanut harvester during use.

[0028] The transmission assembly 4 includes a driven roller 41 rotatably connected to the mounting frame 1, a driven roller 3 43 rotatably mounted on the mounting frame 1 is arranged on one side of the driven roller 41, and a driven roller 2 42 rotatably connected to the mounting frame 1 is arranged between the driven roller 3 43 and the driven roller 1 41, wherein the driven roller 1 41, the driven roller 2 42 and the driven roller 3 43 are installed in the conveying grid 31, so that when the driven roller 1 41, the driven roller 2 42 and the driven roller 3 43 rotate, they can effectively transmit power to the conveying grid 31, thereby causing the conveying grid 31 to shift.

[0029] Gears 44 are fixedly installed on one end of the driven roller 1 41, both ends of the driven roller 2 42 and both ends of the driven roller 3 43, and a transmission chain 45 is connected between the two gears 44 on the same side. Through the transmission of the transmission chain 45, when the driven roller 3 43 rotates, the driven roller 1 41 and the driven roller 2 42 can effectively rotate synchronously.

[0030] The gear 44 at the other end of the driven roller three 43 is connected to the power parts of the peanut harvester through a transmission chain 45. After the connection is completed, when the user starts the peanut harvester, the driven roller three 43 is rotated. When the driven roller three 43 rotates, the driven roller one 41 and the driven roller two 42 are driven to rotate synchronously. When the driven roller one 41, the driven roller two 42 and the driven roller three 43 rotate, the conveying grid 31 starts to rotate effectively. Embodiment 2

[0031] like Figure 6-7 As shown, in the second embodiment, other structures remain unchanged.

[0032] The two vertical plates of the mounting frame 1 are changed into flat straight plates, and then side plates 5, telescopic curved rods 51, and springs 52 are added on both sides. The side plates 5 here are the curved surfaces of the mounting frame 1, and the ends are also designed in an eight-shaped shape. The driven rollers pass through the internal slots and are connected to the mounting frame 1. When the peanut harvester is in use, the peanut plants press the side plates 5 to rotate. The advantage of this compared with the first embodiment is that the problem of bending the peanut plants is smaller, thereby further ensuring the integrity of the peanut plants. In addition, the telescopic curved rods 51 and springs 52 provide a good instantaneous buffer for the peanut plants, thereby further reducing the situation where the peanut plants are blocked by the mounting frame 1 and fall directly.
