Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to an agricultural machinery adjusting device. Background Art

[0002] At present, the degree of mechanization in agricultural planting is very high, and agricultural machinery for various purposes emerges in an endless stream. Therefore, special connecting devices are needed to connect agricultural machinery for various purposes to the rear of tractors and other traction machinery for operation.

[0003] Through searching, it is found that the connection device of a garden management machine and agricultural implements with announcement number CN208549168U includes a connecting seat, on which a cross beam extending to both sides is fixed, and on the end of the cross beam a support seat extending obliquely downward is fixed, and the cross beam and the support seat are used to be fixedly connected to the body of the garden management machine to fix the connecting seat; the connecting seat is symmetrically hinged with a suspension rod extending backward, and the suspension rod rotates up and down with the hinge point at its end as the center, and the end of the suspension rod is also provided with a hinge hole for connecting with agricultural implements; a gearbox is fixed to the upper surface of the connecting seat, and the power output shaft of the gearbox is located in the middle of the two suspension rods and extends backward, and is used to connect with agricultural implements and output power.

[0004] However, the above-mentioned farm management machine and agricultural implement connection device can only allow the agricultural implement connected at the back to move up and down. At present, in the process of agricultural planting, this agricultural implement connection device that can only move up and down has the following problems: during operation, the wheels of the tractor or other traction machinery in front of the connection device need to stand between the ridges of each row of crops to prevent the crops from being crushed. However, at this time, the agricultural implements at the back will not correspond to each row of crops that need to be operated. For example, when it is necessary to loosen the soil between the ridges of crops, the loosening machine will be directly above each row of crops and cannot correspond to the ridges; for example, when it is necessary to spray pesticides on each row of crops, the spraying machine nozzle connected to the back of the connection device is located between the ridges and cannot correspond to the top of each row of crops. Therefore, it is particularly important to design a horizontally adjustable agricultural implement connection device to solve the above problems. Utility Model Content

[0017] 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.

[0018] See also Figure 1-4 The utility model provides an agricultural implement adjustment device, comprising two connecting arms 1, the rear end of the connecting arm 1 is movably connected to an adjustment arm 2, the front end of the connecting arm 1 is fixedly connected to an adjustment device 3, the front end upper surface of the adjustment arm 2 is fixedly connected to a connection ear 4, and the upper end of the connection ear 4 is hinged to an upper connecting arm 5; the adjustment device 3 comprises two parallel guide cylinders 301, the two guide cylinders 301 are fixedly connected by three connecting blocks 302, a guide rod 303 is slidably connected in the guide cylinder 301, and both ends of the guide rod 303 are fixedly connected to connecting pieces 304, The upper ends of the two connecting members 304 are fixedly connected by a U-shaped frame 305, and the upper end of the connecting block 302 located on the far left is fixedly connected to an upper extension plate 306, and the right side surface of the upper extension plate 306 is connected to the bottom end of the upper cylinder 307, and the telescopic rod end of the upper cylinder 307 is connected to a connecting member 304 on the right side, and the lower end of the connecting block 302 located on the far right is fixedly connected to a lower extension plate 308, and the left side surface of the lower extension plate 308 is connected to the bottom end of the lower cylinder 309, and the telescopic rod end of the lower cylinder 309 is connected to a connecting member 304 on the left side.

[0019] A connecting ear 3051 is fixedly connected to the middle of the upper end of the U-shaped frame 305 .

[0020] The rear end of the connecting piece 304 is fixedly connected with a second connecting ear 3041 .

[0021] Among them, the front upper and lower ends of the adjusting arm 2 are both provided with a plurality of limiting grooves 201 , the front end of the connecting arm 1 is provided with a slideway 101 adapted to the adjusting arm 2 , and the upper and lower ends of the slideway 101 are plugged with limiting pins 102 .

[0022] By setting a plurality of limiting grooves 201, slideways 101, and limiting pins 102, the limiting pin 102 can be pulled out according to the actual situation during on-site use, and the length of the adjusting arm 2 extending into the slideway 101 can be adjusted. After the adjustment is completed, the pin 102 is inserted into the connecting arm 1 again, and the limiting of the adjusting arm 2 can be completed at this time.

[0023] Working principle: Before use, first hinge the rear ends of the two adjusting arms 2 of the agricultural implement adjusting device to the lower connecting piece at the rear end of the tractor through a latch, and then hinge the rear ends of the two upper connecting arms 5 to the hydraulic lifting arm at the upper rear end of the tractor through a latch.

At this time, drive the tractor to the edge of the farmland that needs to be cultivated so that the two rows of wheels of the tractor are located between the ridges. There are no crops between the ridges, so there is no situation of crushing the crops. For example, at this time, the agricultural machinery connected to the two connecting ears 3041 and the connecting ear 1 3051 needs to loosen the soil between the ridges, but the loosening part of the agricultural machinery is just above the ridge, that is, above the crop. At this time, the upper cylinder 307 can be controlled to extend and the lower cylinder 309 can be controlled to contract, or the upper cylinder 307 can be controlled to contract and the lower cylinder 309 can be controlled to extend, thereby driving the agricultural machinery connected to the two connecting ears 3041 and the connecting ear 1 3051 to adjust to the left or right, so that the loosening part of the agricultural machinery adjustment device is just located between the ridges, and the tractor can walk to loosen the ridges.
