Problems solved by technology

There are following defects: one, when taking seed, the fluidity of seed is poor, it is inconvenient to take kind
2. Due to the accumulation of seeds, it is easy to cause too many seeds to be taken, resulting in a high reabsorption rate
3. The seeds are piled up in the seed-filling chamber, causing damage to the surface of the seeds when taking the seeds

Embodiment 1

[0030] A seed box connection device for a metering device, including a cylinder body 1 and at least two seed guide plates 2. This embodiment takes three pieces as an example for illustration; the seed guide plates 2 are arranged up and down on the inner wall of the cylinder body 1, and two adjacent The seed guide plate 2 is relatively arranged, and the seed guide plate 2 on the top is inclined downward toward the seed guide plate 2 opposite to it at the bottom. Outlet of cylinder 1.

[0031] The seed guide plate 2 includes a connecting section 3 and a guiding section 4 , the guiding section 4 is arranged obliquely below the connecting section 3 , and the connecting section 3 is connected with the cylinder body 1 . Connecting tabs 5 protrude from both sides of the connecting section 3 of the seed guide plate 2 , and a chute 6 is vertically opened at the joint between the cylinder body 1 and the seed guide plate 2 , and the tabs 5 are connected in the chute 6 . The angle betwee...

Embodiment 2

[0034] This embodiment differs from Example 1 in that: the corresponding part or all of the seed guide plate 2 on the cylinder body 1 is provided with a guide section slot at the connection position, and the guide section 4 of the seed guide plate 2 passes through the guide section 4 from the outside of the cylinder body 1. The section slot is inserted into the cylinder body 1, and the connecting section 3 of the seed guide plate 2 is fixedly connected with the cylinder body 1. Preferably, the connecting section 3 of the seed guiding plate 2 is provided with a threaded hole 9 , and the connecting section 3 is connected with the threaded hole 9 through bolts to fix the barrel 1 and the seed guiding plate 2 .

Embodiment 3

[0036] The difference between this embodiment and Examples 1 and 2 is that the seed guide plate 2 located at the bottom is set in the manner of Embodiment 2, and the other seed guide plates 2 are set in the manner of Embodiment 1.

[0037] The working process and working principle of the present invention: the present invention makes the seed flow in a zigzag circuitous flow by arranging a plurality of seed guide plates staggered in the cylinder, and the size and angle of the seed guide plates can be determined according to the needs of the seeds. When the seeds reach the seed filling chamber through the present invention, they are affected by the seed guide plate, so that the seeds cannot directly reach the seed filling chamber, and the seeds are stratified by several times of the seed guide plate, so that the seeds arriving at the seed filling chamber are in a state of one layer To achieve the role of stratification.

Abstract

The invention discloses a connecting device for a seed box of a seed-metering device. The connecting device comprises a cylinder and at least two seed guide plates, wherein the seed guide plates are arranged on the inner wall of the cylinder in an up and down manner, two adjacent seed guide plates are opposite, and the upper seed guide plate inclines downwards toward the lower opposite seed guide plate. According to the connecting device, a plurality of seed guide plates are arranged in the cylinder in a staggered manner so that seeds flow in a 'Z' shape, cannot directly reach a seed supplementing chamber due to the effect of the seed guide plates in the flowing process, are layered through the effect of the seed guide plates for a plurality of times, and reach the seed supplementing chamber in a layering manner so as to achieve the layering effect.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a connection device for a seed box of a seed meter. Background technique [0002] In recent years, direct seeding of rice is a main way of rice planting, which saves labor and labor and is low in cost. In the existing rice precision hole direct seeding machine, its seed metering device contacts with the seeds in a piled shape. There are following defects: one, when taking seeds, the fluidity of seeds is poor, and it is inconvenient to take seeds. 2. Due to the accumulation of seeds, it is easy to cause too many seeds to be taken, resulting in an excessively high reabsorption rate. 3. Seeds are piled up in the seed filling chamber, causing damage to the surface of the seeds when taking the seeds. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the purpose of the present invention is to provide a simple structure, which can rationally st...
