Embodiment 1

[0018] Such as Figure 1 to Figure 6 As shown, a compound side-filling precision seed metering device in this embodiment includes a fixed sorting disk cover (1), a dynamic sequence filling disk (2), a moving ring (3), and a moving duckbill (4) , Fixed duckbill (5), fixed duckbill connecting piece (6), cylindrical torsion spring (7), main fixed shaft (10), saddle-shaped unilateral seed posture adjustment roll (13), ordering shaft ( 15) Seed spacer (18); fixed sorting disk cover (1) is positioned on one side by a shaft shoulder, and the other end is fixed on the main fixed shaft (10) by a pin; dynamic adjustment of seed filling disk (2) and ribs Type sliding bearing 1 (12) with interference fit, assembled on the main fixed shaft (10). One side of the dynamic sequence filling disc (2) is positioned by the shoulder, and the other side is axially limited to the main fixed shaft (10) by a pin. ); The dynamic sequence filling disc (2) has a certain gap between the axial end surface a...

Embodiment 2

[0022] Such as Figure 1 to Figure 6 As shown, a compound side-filling precision metering device in this embodiment includes all the technical features in embodiment 1, in addition, it also includes a saddle-shaped bilateral seed posture adjustment roll (19), a saddle-shaped bilateral The installation method of the seed posture adjustment roll (19) is the same as the installation method of the saddle-type unilateral seed posture adjustment roll (13), and both are removable; the saddle-type bilateral seed posture adjustment roll (19) is opened at both ends The teeth are staggered asymmetrically, and the distance between the two posture adjustment teeth is greater than the maximum diameter of the seed.

[0023] The technical effect achieved by this embodiment is: a detachable and installable saddle-type bilateral seed posture adjustment queuing roll is provided. The saddle-type bilateral seed posture adjustment queuing roll is staggered and asymmetrical, and the distance between th...

Abstract

The invention discloses a compound side-filling precision seed-metering device which comprises a fixed sequencing plate cover, a movable sequence-adjusting seed-filling plate, a saddle-shaped single (double)-side seed posture-adjusting queuing roller and a seed separating plate. A fixed sequencing plate is mounted on a main fixed shaft, and the movable sequence-adjusting seed-filling plate is assembled on the main fixed shaft by being in interference fit with a sliding bearing to form a seed cavity with the fixed sequencing plate cover; and after seeds enter the seed cavity from a seed inlet hole, the seeds enter a seed sequence-adjusting cavity under the action of the seed separating plate, a unique seed discharging opening is formed in the portion, corresponding to the seed throwing cavity, of the fixed sequencing plate cover, and under the combined action of the saddle-shaped single (double)-side seed posture-adjusting queuing roller and a sequencing V-shaped groove formed in the fixed sequencing plate cover, the seeds sequentially enter an axial primary seed filling U-shaped groove and a radial secondary seed filling hole in sequence, the movable sequence-adjusting seed-fillingplate rotates in the operation process, and when the movable sequence-adjusting seed-filling plate rotates to the unique seed discharging opening formed in the fixed sequencing plate cover, the seedsfall into a duckbilled part to complete seed filling. The seed-metering device is simple in structure, continuous and reliable in seed filling, and capable of realizing orderly seed filling and improving the seed filling performance of the seed metering device.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of the core component of a planter, in particular to a compound side-filled precision metering device. Background technique [0002] With the introduction of the national precision agriculture requirements, precision seeding machinery has received widespread attention. The seed meter is the core component of the seeder. The seeding quality of the seeder directly depends on the performance of the seeder. The precise seed metering device in the prior art has poor orderly filling performance, high replay rate and missed seed rate, and complex structure. There is a lack of a precision seed metering device that can realize orderly queuing and filling seeds through simple component adjustment. Summary of the invention [0003] For this reason, the embodiment of the present invention provides a compound side-filling precision seed metering device to solve the problem of orderly seed filling and...
