Description

Technical Field

[0001] The utility model relates to the technical field of seed drill ground wheels, in particular to a side-mounted seed drill ground wheel device. Background Art

[0002] The seed drills currently used in the market are mostly driven by a ground wheel device. In order to avoid interference between the ground wheel device and the seeding and furrowing device, the ground wheel device is mostly placed behind the seed drill and at a large distance from the seed drill. As a result, the overall space occupied by the front and rear of the seed drill is large. When the seed drill needs to turn around at the end of the field, a large turning radius and a large space are required to avoid damage to the seed drill. In addition, the rear-mounted ground wheel is located behind the seed drill, which is not conducive to the operator's observation, resulting in low working efficiency of the seed drill. In addition, the existing ground wheel and the seed drill are mostly connected in a chain drive manner. During the seeding process, the ground wheel will encounter uneven ground and will be affected by hard soil or stones, so that the ground wheel will swing and fluctuate, which will cause the chain to be worn. After the chain is worn, the chain links become longer, resulting in tooth jumping or chain derailment. In severe cases, the chain will be overloaded and broken, and the transmission stability is poor. Therefore, the existing seed drill ground wheel has certain limitations.

[0003] Therefore, a side-mounted ground wheel device for a seed drill is needed to solve the above-mentioned problems. Utility Model Content

[0004] The utility model provides a side-mounted ground wheel device for a seed drill, in which the ground wheel is arranged on the side of the seed drill, thereby shortening the distance between the seed drill and the ground wheel and avoiding damage to the side-mounted ground wheel device when turning around at the field head. At the same time, the device is connected to the ground wheel through a universal coupling, so that the transmission of the ground wheel is not affected by the swing or fluctuation of the ground wheel, thereby improving the stability of the ground wheel transmission.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A side-mounted ground wheel device for a seeder includes a ground wheel support arm, the upper end of the ground wheel support arm is rotatably mounted on the side of the seeder, a first transmission is mounted on the lower end of the ground wheel support arm, the first transmission is arranged on the outer side of the ground wheel support arm, an input shaft of the first transmission passes through the ground wheel support arm and is fixedly mounted with a ground wheel, an output shaft of the first transmission is transmission-connected with a universal coupling, a second transmission is fixedly mounted on the side of the seeder, and the other end of the universal coupling is connected to the input shaft of the second transmission.

[0007] As a preferred technical solution, a pin is installed on the side wall of the seeder, and the upper end of the ground wheel support arm is rotatably installed on the pin.

[0008] As a preferred technical solution, the universal coupling includes a universal output shaft, which is connected to a spline sleeve through a first universal joint, a spline shaft is slidably installed in the spline sleeve along the extension direction of the spline sleeve, and the spline shaft is connected to a universal input shaft through a second universal joint, the universal input shaft is connected to the output shaft of the first transmission, and the universal output shaft is connected to the input shaft of the second transmission.

[0009] As a preferred technical solution, the second transmission is arranged above the pin shaft.

[0010] As a preferred technical solution, the output shaft of the second transmission is connected to a seeding shaft on the seeder for sowing.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0012] Since the side-mounted ground wheel device of the seeder includes a ground wheel support arm and a universal coupling, when the device is used for sowing, the lower end of the ground wheel is pressed against the ground, and then under the traction of the seeder, the ground wheel rotates, the ground wheel drives the first transmission to work, the first transmission drives the universal coupling, the universal coupling drives the second transmission to work, and the second transmission drives the seeding shaft of the seeder for sowing to work, thereby realizing ground wheel driven sowing operation. When the ground wheel encounters uneven ground, the ground wheel will be pushed upward by harder soil or stones, the ground wheel support arm rotates upward, the spline shaft slides in the spline sleeve, and the two universal joints rotate according to the floating angle of the ground wheel, thereby responding to the swing or fluctuation of the ground wheel. Corresponding buffering, in the utility model, the ground wheel is arranged on the side of the seeder, which shortens the distance between the seeder and the ground wheel and avoids damage to the side-mounted ground wheel device when turning around at the head of the field. At the same time, the device is connected to the ground wheel through a universal coupling. Compared with the traditional chain drive, the transmission method of the ground wheel in the device has certain flexibility. When the ground wheel swings or fluctuates under force, the universal coupling can automatically compensate through the spline sleeve and the spline shaft and the first universal joint and the second universal joint, so as to ensure the normal operation of the ground wheel transmission system, so that the transmission of the ground wheel is not affected by the swing or fluctuation of the ground wheel, thereby improving the sowing efficiency and making the device suitable for a variety of sowing operation environments.

[0013] Since the side-mounted ground wheel device of the seeder includes a ground wheel support arm rotatably installed on the side of the seeder through a pin shaft, the pin shaft can withstand a certain bending moment. During the sowing process, the ground wheel will inevitably be affected by hard soil or stones, causing the ground wheel to swing or fluctuate. The ground wheel support arm connected by the pin shaft can withstand a certain swing and fluctuation, thereby making the ground wheel work more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
