Description

Technical Field

[0001] This application relates to the technical field of equipment for seeders, and more specifically, to a seed storage hopper for agricultural machinery. Background Technology

[0002] During the sowing process in farmland, it is inevitable to use the seed storage hopper of the agricultural machine to temporarily store the seeds.

[0003] The prior art publication number CN222981979U provides a storage hopper for agricultural machinery seeding. This device, by setting up a distribution pipe, a rotating shaft and a distribution trough, enables the storage hopper for agricultural machinery seeding to continuously sow seeds into the soil one seed at a time, avoiding high sowing density during the sowing process, thus improving the seed survival rate.

[0004] While the existing technical solutions described above can effectively avoid the problem of excessive seeding density, they still have the following drawbacks: These solutions mainly rely on gravity to transport seeds downwards; however, sticky seeds or coating agents may accumulate and clog at the conical bottom of the hopper and the discharge pipe, severely affecting the uniformity of seed sowing and hindering healthy crop growth. Therefore, we propose an agricultural machinery seeding hopper. Utility Model Content

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses an agricultural machinery seeding storage hopper, comprising: a storage hopper body 1, a top cover 2 installed on the top of the storage hopper body 1, a feed pipe 4 passing through one side of the top cover 2, a discharge pipe 3 fixedly connected to the lower side of the storage hopper body 1, the discharge pipe 3 being connected to external seeding equipment, a dredging frame installed inside the storage hopper body 1, and a lifting mechanism also installed inside the storage hopper body 1, the lifting mechanism being used to drive the dredging frame to move up and down, the lower end of the dredging frame extending into the inner cavity of the discharge pipe 3.

[0029] The dredging frame includes a drive ring 10, and multiple first push rods 6 are fixedly installed on the lower side of the drive ring 10. Second push rods 12 are fixedly connected to the outer side of the first push rods 6, and the second push rods 12 are set in an inclined structure.

[0030] The lifting mechanism includes a fixed housing 8 fixedly installed inside the storage hopper body 1. A reciprocating screw 9 is rotatably connected inside the fixed housing 8. The driving ring 10 is slidably engaged with the reciprocating screw 9. Multiple limiting rods 13 are slidably inserted through one side of the fixed housing 8. The limiting rods 13 are fixedly connected between the driving ring 10 and the first push rod 6. A rotating mechanism is also installed on one side of the fixed housing 8. The rotating mechanism is used to drive the reciprocating screw 9 to rotate.

[0031] The rotating mechanism includes a motor 11 fixedly mounted on the top cover 2. A spline sleeve 15 is fixedly connected to the output end of the motor 11. A drive rod 5 is rotatably mounted on the fixed housing 8. One end of the drive rod 5 is fixedly connected to a reciprocating lead screw 9, and the other end of the drive rod 5 is fixedly connected to a spline rod 14. The spline rod 14 and the spline sleeve 15 are inserted into each other. The spline rod 14 and the spline sleeve 15 allow the user to quickly separate the top cover 2 and the storage hopper body 1, making it convenient for the user to inspect the inside of the storage hopper body 1.

[0032] During sowing, when storing sticky seeds or coating agents in the hopper body 1, as the seeds fall out continuously, the motor 11 runs, the drive rod 5 drives the reciprocating screw 9 to rotate, and the drive ring 10 then drives the first push rod 6 and the second push rod 12 to move up and down reciprocally below the hopper body 1 and inside the discharge pipe 3, clearing the discharge pipe 3, thereby ensuring that the seeds can pass through the discharge pipe 3 smoothly, avoiding the accumulation and blockage of seeds in the discharge pipe 3, and effectively ensuring the smooth progress of sowing.

[0033] Reference Figure 2 Several stirring rods 7 are also fixedly connected to the drive rod 5. The stirring rods 7 are made of silicone material.

[0034] During the rotation of the drive rod 5, the stirring rod 7 will rotate accordingly, stirring and dispersing the seeds adhering inside the storage hopper body 1, further reducing the probability of seed accumulation and blockage; at the same time, since the stirring rod 7 is made of silicone material, it can effectively prevent seed damage.

[0035] This application, by setting up a dredging frame and a lifting mechanism, can dredge the discharge pipe 3, preventing seeds from accumulating and clogging inside the discharge pipe 3, and effectively ensuring the smooth progress of sowing; at the same time, by setting up a stirring rod 7, it can stir and disperse the seeds adhering inside the storage hopper body 1, further reducing the probability of seed accumulation and clogging.

[0036] The implementation principle of a seed storage hopper in this application embodiment is as follows: When relevant personnel need to use this technical solution to store sticky seeds or coating agents during sowing, as the seeds fall outwards, the motor 11 runs, the drive rod 5 drives the reciprocating screw 9 to rotate, and the drive ring 10 then drives the first push rod 6 and the second push rod 12 to reciprocate up and down below the storage hopper body 1 and inside the discharge pipe 3, clearing the discharge pipe 3 and reducing the probability of blockage. At the same time, the stirring rod 7 will rotate with the drive rod 5, further reducing the probability of seed accumulation and blockage. This continuous operation ensures the smooth outward delivery of seeds.
