Detailed Description
The invention will be further described with reference to the accompanying drawings.
The front and rear drum structure of a seeding machine as shown in fig. 1 comprises a seeding machine 1, wherein a front drum 2 and a rear drum 3 are arranged on the seeding machine 1, when the seeding machine 1 runs on a soft soil surface, the front drum 2 and the rear drum 3 roll on the soft soil surface to play a role in flattening soil, and meanwhile, the front drum 2 and the rear drum 3 are running wheels of the seeding machine 1 on the soft soil surface. The front end of the seeder 1 can be tilted, so that the front roller 2 is suspended. When the seeder 1 needs to turn around in the seeding process, an operator firstly lifts the front end of the seeder 1, then the operator re-applies force, and one side of the rear roller 3 is used as a rotation fulcrum to push the seeder 1 to rotate, so that the turning around of the seeder 1 is realized.
The front rolling plates 4 are arranged on two sides of the front roller 2, and the outer diameter of the front rolling plates 4 is larger than that of the front roller 2, so that when the seeder 1 runs on the soft soil surface, the cylindrical surface of the front roller 2 is in rolling contact with the soft soil surface, and the sheet structure of the front rolling plates 4 presses out the guide grooves on the soft soil surface. The two sides of the rear roller 3 are provided with rear rolling discs 5, the outer diameter of the rear rolling discs 5 is larger than that of the rear roller 3, and the rear rolling discs 5 are thicker than the front rolling sheets 4, so that when the seeder 1 is stationary on a soft soil surface, the rear rolling discs 5 cannot sink into the soft soil surface as the front rolling sheets 4, and the rear rolling discs 5 can support the rear roller 3 on the soft soil surface, so that the rear roller 3 is separated from the ground. The positions of the back rolling disc 5 and the front rolling piece 4 are opposite, when the seeder 1 runs on the soft soil surface, the back rolling disc 5 correspondingly runs into the guide groove, and the guide groove is formed on the soft soil surface, so that the back rolling disc 5 can be sunk into the soft soil surface along the guide groove pressed out by the front rolling piece 4, the back rolling disc 5 can not support the back roller 3 to be separated from the ground in the running process of the seeder 1, and the back roller 3 still can be in rolling contact with the soft soil surface after the seeder 1 runs.
Due to the existence of the front rolling plate 4 and the rear rolling plate 5, when the seeder 1 needs to turn around, the front end of the seeder 1 is tilted firstly, an operator tilts the front end of the seeder 1, then the seeder 1 advances to the rear rolling plate 5 to drive out of the guide ditch, the rear rolling plate 5 is not sunk into soil, the rear roller 3 is separated from the ground under the supporting action of the rear rolling plate 5, the rear roller 3 does not directly generate interaction force with the soil surface at the moment, and the operator can control the turning operation more easily.

In this case, if the rear drum 3 is a driven wheel, the turn is directly made; if the rear roller 3 is a driving wheel which actively rotates, the power source of the rear roller 3 is cut off and then turned around. If the power source is not cut off during turning around, the rear roller 3 can drive the rear roller disc 5 to rotate, so that the rotation of the rear roller disc 5 can cut groove marks on the soft soil surface, the rear roller disc 5 is sunk into the soft soil surface, and the rotating rear roller disc 5 is not easy to control. And under the condition that the power source of the rear roller 3 is cut off equally, compared with the independent rear roller 3, the scheme of adding the rear roller disc 5 on the rear roller 3 in the application can enable the rear roller 3 to leave the ground when rotating, only the rear roller disc 5 is used for contacting the soft soil surface, the contact area with the soil surface is smaller, the friction effect is smaller, and the labor is saved when turning around.
In a more preferred embodiment, two front rolling plates 4 are fixed at two sides of the front roller 2, and the front roller 2 rotates to drive the front rolling plates 4 to rotate together. The two back rolling discs 5 are movably connected to two sides of the back roller 3, and the back rolling discs 5 and the back roller 3 can rotate independently. When turning around, the rear rolling disc 5 can not rotate the roller 3, so that the operation of cutting off the power source of the rear roller 3 can be omitted, and the operation is more convenient. Specifically, the front roller 2 is mounted on the planter 1 through a front rotating shaft, and the front rolling plate 4 is fixedly mounted on the front rotating shaft, so that the front rolling plate 4 can rotate together with the front roller 2. The rear roller 3 is arranged on the seeder 1 through a rear rotating shaft, and the rear rolling disc 5 is arranged on the rear rotating shaft through a bearing, so that the rear rolling disc 5 and the rear roller 3 can rotate independently.

The edge of the front rolling piece 4 is provided with a plurality of tooth-shaped structures, so that the front rolling piece 4 presses out a non-linear guide groove with teeth on a soft soil surface, and on the premise that the width of the guide groove is unchanged, the non-linear guide groove can press out more groove body space on the soft soil surface compared with a linear guide groove, so that a thicker rear rolling disc 5 is more easily sunk into the soft soil surface along the guide groove. In a preferred embodiment, a plurality of tooth grooves 6 are respectively formed on the two side surfaces of the front rolling plate 4, the tooth grooves 6 extend to the edge of the front rolling plate 4 and form a tooth-shaped structure, and the tooth grooves 6 on the two sides of the front rolling plate 4 are staggered.
The front roller 2 and the rear roller 3 are both cylinders, the front rolling plates 4 are round plate bodies concentrically arranged at two sides of the front roller 2, and the rear rolling plates 5 are round plate bodies concentrically arranged at two sides of the rear roller 3; the outer diameters of the front roller 2 and the rear roller 3 are consistent, and the outer diameter of the rear rolling disc 5 is slightly smaller than the outer diameter of the front rolling disc 4, so that the front rolling disc 4 can press deeper guide grooves on the soft soil surface, and the deeper guide grooves can accommodate thicker rear rolling disc 5 more easily.
The rear part of the seeder 1 is provided with an armrest 7, and the front end of the seeder 1 can be tilted by pressing the armrest 7.
