Description

Technical Field

[0001] The present invention relates to the field of weeders, and more particularly to a crop weeder for ridge planting. Background Art

[0002] Ridge distribution means that the land is arranged into raised ridges, and crops are planted on the ridges. Grooves are formed between the ridges. This planting method helps to improve the soil environment, crop yield and quality. Since crops are not harvested at the same time, the crops planted on adjacent ridges may be different, or even if the crops planted on the same ridge are the same, some of them have not been harvested yet. Existing weeders cannot meet the weeding requirements of the above scenarios.

[0003] Therefore, it is necessary to provide a crop weeder for ridge planting to solve the above technical problems. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a crop weeder for ridge planting.

[0005] A crop weeder for ridge planting provided by the present invention includes a mounting seat for connecting with a tractor. A U-shaped frame is fixed on the top of the mounting seat. A rotating shaft is rotatably connected inside the U-shaped frame. A driving assembly for driving the rotating shaft to rotate is installed on the U-shaped frame. A plurality of weeding assemblies are equidistantly installed on the rotating shaft. Since crops are distributed in ridges, a groove is provided between adjacent ridges, and the groove can be used for the tractor to travel. The weeding assembly includes a fixed disk and a connecting disk fixed on the rotating shaft. A driving shaft is rotatably connected between the fixed disk and the connecting disk at equal angles. A weeding blade is fixed on the driving shaft. An adjusting device for driving the driving shaft to rotate is installed on the fixed disk.

[0006] The soil on the ridge is cut by the combination of the weeding blade and the rotation of the rotating shaft, so that the grass is shoveled off the ridge.

[0007] Preferably, the adjusting device includes a turntable rotatably connected to the rotating shaft. A connecting column is fixed on one side of the turntable. An ear plate is fixed on the side wall of the rotating shaft. An electric push rod is hinged between the connecting column and the ear plate. A groove is provided on the side of the turntable opposite to the connecting column. A driving gear is fixed in the groove. One end of the driving shaft is fixed with a driven gear, and the driven gear is meshed with the driving gear.

[0008] The electric push rod contracts to drive the turntable to rotate, and then the driving gear drives the driven gear and the drive shaft to rotate together, so that the weeding blade moves into the fixed disk and the connecting disk. At this time, when the rotating shaft rotates, this weeding component cannot perform weeding. Since crops are not harvested at the same time, the crops planted on adjacent ridges are different, or the crops planted on the same ridge are different, or even if the crops planted on the same ridge are the same, but some are not harvested, the weeding blade of the weeding component can be controlled to extend and contract. To meet the needs of different weeding scenarios.

[0009] Preferably, the fixed disk and the connecting disk have the same diameter. When the electric push rod shortens, the weeding blade moves between the fixed disk and the connecting disk.

[0010] Preferably, an arc-shaped plate is fixed inside the U-shaped frame, and the arc-shaped plate is arranged facing the weeding blade to prevent soil and weeds from splashing.

[0011] Preferably, the weeding blades on adjacent drive shafts of the same weeding component are arranged at intervals, and the weeding effect is better.

[0012] Preferably, the driving component includes an engine, a driving pulley is fixed at the output end of the engine, a driven pulley is fixed at one end of the rotating shaft, and the driven pulley and the driving pulley are connected by a belt drive. The engine drives the rotating shaft to rotate.

[0013] Preferably, the mounting seat is provided with a mounting plate for connecting with a tractor.

[0014] Preferably, at least four drive shafts of the same weeding component 5 are provided, and the weeding effect is good.

[0015] Compared with the related technology, the present invention has the following beneficial effects: Flexible adjustment: Through the adjustment device, the extension and contraction of the weeding blade can be flexibly controlled to meet the growth state of crops on different ridges and the weeding requirements, realize precise weeding operations, and this weeding machine can adapt to the needs of different crops and planting patterns, with wide applicability.

Specific embodiments

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Please refer to Figures 1 - 5 , a crop weeding machine for ridge planting, which is ingeniously designed and practical, and is specifically designed to adapt to the planting mode of ridge-shaped distribution of crops. The weeding machine mainly includes a mounting base 1 for stably connecting with a tractor, and a U-shaped frame 2 is fixedly installed on the top of the mounting base 1. A rotating shaft 3 is rotatably connected inside the U-shaped frame 2 through components such as bearings. This rotating shaft 3 is the core rotating component of the weeding machine. On the U-shaped frame 2, a drive assembly 4 for driving the rotation of the rotating shaft 3 is also installed to ensure that the rotating shaft 3 can rotate stably and powerfully.

[0020] A number of weeding assemblies 5 are equidistantly installed on the rotating shaft 3. These weeding assemblies 5 are the key to the weeding function of the weeding machine. Since crops are distributed in ridges in the field, there are troughs between adjacent ridges. These troughs not only provide space for the tractor to travel, but also indirectly affect the design of the weeding machine. Each weeding assembly 5 includes a fixed disk 51 fixed on the rotating shaft 3 and a connecting disk 52. A number of drive shafts 53 are rotatably connected between the fixed disk 51 and the connecting disk 52 at equal angles. A weeding blade 54 is fixedly installed on each drive shaft 53. When the rotating shaft 3 rotates, the weeding blade 54 will rotate accordingly, cutting the soil on the ridge of the soil bank, so as to shovel the grass off the ridge of the soil bank.

[0021] In order to meet the needs of different weeding scenarios, an adjustment device 6 for driving the drive shaft 53 to rotate is installed on the fixed disk 51 of each weeding component 5. The adjustment device 6 includes a turntable 61 rotatably connected to the rotating shaft 3, a connecting column 62 is fixed to one side of the turntable 61, and an ear plate 63 is fixed to the side wall of the rotating shaft 3. The connecting column 62 and the ear plate 63 are hinged by an electric push rod 64. When the electric push rod 64 contracts, it drives the turntable 61 to rotate. A groove 65 is provided on the side of the turntable 61 facing away from the connecting column 62, and a driving gear 66 is fixed in the groove 65, and a driven gear 67 is fixed to one end of each driving shaft 53, and these driven gears 67 are meshed and connected with the driving gear 66. Therefore, when the turntable 61 rotates, the driving gear 66 will drive the driven gear 67 and the drive shaft 53 to rotate together, so that the weeding blade 54 moves to the space between the fixed disk 51 and the connecting disk 52 (the weeding blade 54 is hidden between the fixed disk 51 and the connecting disk 52 and does not protrude). At this time, even if the rotating shaft 3 continues to rotate, the weeding component 5 cannot perform weeding operations. Since crops are not harvested at the same time, the crops planted in adjacent ridges may be different, or even if the crops planted in the same ridge are the same, some have not yet been harvested. Therefore, the extension and retraction of the weeding blade 54 of the weeding component 5 can be flexibly controlled by controlling the extension and retraction of the electric push rod 64, thereby meeting the needs of different weeding scenarios.

[0022] The diameters of the fixed disk 51 and the connecting disk 52 are designed to be the same to ensure that the weeding blade 54 can be positioned steadily and accurately during movement. When the electric push rod 64 is shortened, the weeding blade 54 will move between the fixed disk 51 and the connecting disk 52 to close the weeding function.

[0023] In addition, an arc plate 7 is fixedly installed on the inner side of the U-shaped frame 2. The arc plate 7 is arranged opposite to the weeding blade 54, which can effectively prevent soil and weeds from being blown away during the weeding process and keep the working environment clean.

[0024] The weeding blades 54 on adjacent driving shafts 53 of the same weeding assembly 5 are arranged at intervals. Such a design can make the weeding effect more uniform and thorough.

[0025] The driving assembly 4 includes an engine 41, a driving pulley 42 is fixed to the output end of the engine 41, and a driven pulley 43 is fixed to one end of the rotating shaft 3. The driven pulley 43 and the driving pulley 42 are connected by a belt 44, so that the engine 41 drives the rotating shaft 3 to rotate.

[0026] The mounting seat 1 is also provided with a mounting plate 8 connected to the tractor. The mounting plate 8 ensures that the weeder can be firmly connected to the tractor, providing stable power support for the weeding operation.

[0027] There are at least four drive shafts 53 of the same weeding component 5. Such a design can ensure that the weeding blades 54 can cover a wider area during rotation, thereby achieving a better weeding effect.

[0028] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
