Description

Technical Field

[0001] The utility model relates to the technical field of corn direct seeding soil covering and taking, in particular to a corn direct seeder. Background Technique

[0002] A direct seeder is a seeding machine that sows corn seeds into the soil. In the land in the rocky mountain area environment, due to environmental impacts, it is difficult for large equipment to carry out seeding operations. Therefore, it is necessary to use a seeding machine with a smaller volume to sow the soil. The hopper of the existing small soil seeding machine will cause the feeding pipe to be blocked due to the rapid discharge of seeds. As a result, when cleaning the seeds in the hopper, it is necessary to clean the seeds in the hopper outward through a container to clean the seeds at the connection between the hopper and the feeding pipe, resulting in difficult cleaning.

[0003] Patent CN215912511U discloses a direct seeder for intercropping soybeans in corn fields in rocky mountain areas, including a seed hopper. Locking plates are arranged on both side surfaces of the seed hopper to fix it on the armrest of agricultural equipment. A gearbox is fixed on one end surface of the seed hopper and located at the bottom of the locking plate. The gearbox includes a belt drive with a driving wheel of agricultural equipment and a driven gear set that decelerates by driving the driving wheel. A discharge pipe is arranged in the seed hopper. One first bearing is embedded on each side of the seed hopper. A universal joint is installed on the first bearing close to one end of the driving wheel. One end of the discharge pipe passes through the first bearing and is connected to the driving wheel. The end of the discharge pipe far from the driving wheel inclines downward and is connected to the universal joint. A material opening located in the seed hopper is arranged in the middle of the discharge pipe. The universal joint is communicated with the discharge pipe, and a retaining cap is threadedly connected to the outer end of the universal joint.

The leveling frame 7 under the mounting frame 1 will complete the soil covering.

[0029] Working principle: Firstly, a front wheel 5 and a rear wheel 9 are respectively rotatably connected to the front and rear of the mounting frame 1. A rotating rod 61 is rotatably connected inside the front wheel 5. A rotating shaft 65 is rotatably connected outside the hopper 2 and the support rod 4. And the front wheel 5 is fixed to the outer wall of the rotating rod 61. When the push rod 10 is pushed to make the device move forward, the front wheel 5 rotates forward. In order to dig a pit, a fixing rod 812 is also fixed between the front wheel 5 and the rear wheel 9 under the frame. A soil covering angle 813 is fixed at one end of the fixing rod 812 close to the front wheel 5. The soil covering angle 813 adopts a plowshare, and the plowshare is used for digging the pit. In order to realize the seeding function, a hopper 2 is also fixed on the mounting frame 1. A rotating shaft 65 is rotatably connected inside the hopper 2. A sleeve 66 is sleeved on the outer wall of the rotating shaft 65. Multiple groups of brushes 67 are inserted on the outer wall of the sleeve 66. And a fitting plate 814 fixedly connected to one side of the hopper 2 is provided with a plurality of through holes 815 along the axis of the hopper 2. A blanking box 810 is fixedly connected to the bottom of the hopper 2. And a flip cover 3 is also arranged on the hopper 2, which effectively prevents the seeds in the hopper 2 from overflowing during transportation, and at the same time is convenient for the operator to observe and add seeds. The hopper 2 is used for storing corn seeds. A rotating shaft 65 is fixed to the end face of the hopper 2. A driven wheel 64 is fixed to the end of the rotating shaft 65 far from the hopper 2. And a driving wheel 62 and the driven wheel 64 are connected by a belt 63. At the same time, a turntable 81 is also sleeved on the end of the rotating shaft 65 far from the driven wheel 64. The turntable 81 is equidistantly provided with sliders 82. The sliders 82 can continuously contact the movable plate 83, so that the movable plate 83 changes its angle on the support rod 4. At this time, one end of the movable plate 83 is lifted. The movable plate 83 drives the rotating plate 86 to move simultaneously. A spring 84 is provided. The other end of the spring 84 connects the movable plate 83 and the mounting plate 85, which is convenient for the movable plate 83 to reset. The mounting plate 85 and the support rod 4 are connected by bolts. When the rotating plate 86 rotates, the rotating plate 86 drives the connecting rod 87 to move.

A clogging prevention plate 816 is also provided in the feeding box 810. With the setting of the clogging prevention plate 816, the corn seeds are prevented from splashing everywhere, greatly increasing the accuracy. The corn seeds are discharged from the feeding box 810 through the discharge pipe 811. When the feeding is slow, the user pulls the handle 817, and the handle 817 drives the clogging prevention plate 816 to swing back and forth to tumble the corn seeds in the feeding box 810, greatly improving the working efficiency of corn direct seeding. To achieve the soil covering function, a leveling frame 7 is also fixedly connected to the lower end of the mounting frame 1. To facilitate pushing, a push rod 10 is fixed at one end of the mounting frame 1. The shape of the push rod 10 is V-shaped. The operator can hold the push rod 10 on the mounting frame 1 to push the whole device forward. During the forward movement, the front wheel 5 and the rear wheel 9 of the mounting frame 1 rotate, and the soil covering angle 813 at the end of the fixed rod 812 will create a gully on the ground. When the rotating rod 61 rotates, it will drive the driving wheel 62 to rotate. The driving wheel 62 will drive the driven wheel 64 to rotate through the belt 63. The driven wheel 64 will drive the brush 67 to rotate inside the hopper 2. Every time the sleeve 66 and the brush 67 rotate one circle, the discharge pipe 811 will align with the through holes 815 on the fitting plate 814, and at this time, corn seeds will fall into the gully from the discharge pipe 811 respectively. The leveling frame 7 under the mounting frame 1 will complete the soil covering.
