TECHNICAL FIELD

[0001] The present application relates to the technical field of planting, more particularly to an agricultural seeding device. BACKGROUND

[0002] According to the different types of crops, the planting of seeds is divided into two ways of planting at a certain distance or directly planting without spacing. Manual planting is prone to inaccurate spacing, which affects the growth of crops.

[0003] The prior art document with publication (announcement) number CN219459739U provides an agricultural seeding device. In the related technology of the device, a seeding distance control mechanism is arranged inside the device, a plurality of alignment plates are arranged inside the seeding distance control mechanism, and the staff can control the sliding of the alignment plates on the corresponding positions according to the spacing between the seeds to be planted, so that grooves are formed on the surface of the rotating disc. During the rotation of the rotating disc, the seeds are automatically filled into the grooves and planted at a certain distance on the ground, without the need for manual control of the planting distance, and the planting is convenient and efficient. When non-spaced planting is performed, the grooves on the surface of the rotating disc are closed, the discharge port between the discharge plate and the rotating disc is opened, and the rotating disc is rotated to assist the continuous flow of the seeds for planting.

DETAILED DESCRIPTION

[0035] The present application will be further described in detail below in conjunction with the accompanying drawings.

[0037] handrail frame 1;

[0038] hopper 2, fixedly connected outside the handrail frame 1;

[0039] material guide pipe 3, fixedly connected to one end of the hopper 2 and connected and fixed with the handrail frame 1 through a truss;

[0040] A multi-tube shaft disc 4 for discharging materials is rotatably connected to one end of the armrest frame 1;

[0041] The pitch-adjusting screw 5 is rotatably connected to the interior of the multi-tube shaft disk 4;

[0042] The capstan shaft 6 is slidably connected to the interior of the multi-tube shaft 4 and threadably adapted to the pitch-adjusting screw 5;

[0043] The expansion rod 7 is an annular structure with equal spacing and is hingedly mounted on the outside of the capstan shaft 6;

[0044] The extension tube 8 for discharging is hingedly mounted on the other end of the expansion rod 7 and is slidably connected to the multi-tube shaft disc 4;

[0045] The elastically extendable rubber ring 9 is sleeved and installed on the outside of the plurality of extension tubes 8 .

[0046] The agricultural sowing device drives the winch shaft 6 and the multi-tube disc 4 to slide and contract when the pitch-adjusting screw 5 rotates, so that the extension tube 8 slidably connected inside the multi-tube disc 4 changes the diameter specification of the expansion rubber ring 9 under the extrusion of the expansion rod 7, thereby achieving a flexible adjustment effect of the sowing spacing of the extension tube 8.

[0047] Reference Figure 3 and Figure 1 In the agricultural sowing device described in the embodiment of the present application, a cover plate 21 is installed on one side of the hopper 2 through a torsion spring elastic hinge, and the cover plate 21 is a transparent plate made of acrylic sheet.

[0048] The agricultural sowing device, by utilizing the transparent structural cover 21 installed with elastic hinges, can not only effectively store the crop seeds stored in the hopper 2, but also facilitate observation of the crop capacity status and timely replenishment.

[0049] Reference Figure 3 and Figure 1 In the agricultural sowing device recorded in the embodiment of the present application, one end of the hopper 2 is rotatably connected to an impeller paddle 22, one end of the impeller paddle 22 passes through the hopper 2 and is transmission-connected to a gear shaft 23, the gear shaft 23 is rotationally connected to one side of the handrail frame 1 through a connecting seat, and the gear shaft 23 is meshed and transmission-adapted with the multi-tube shaft disk 4, wherein one end of the impeller paddle 22 is fixedly connected to a rubber rod 24, and the rubber rod 24 can collide with the hopper 2 and the guide tube 3.

[0050] The agricultural sowing device utilizes a multi-tube shaft disk 4 to rotate for planting. The rotating multi-tube shaft disk 4 drives the impeller paddle 22 through the gear shaft 23 for transmission, so that the rotating impeller paddle 22 follows the movement of the multi-tube shaft disk 4 to release the quantity of crop seeds in a quantitative manner, thereby improving the planting effect. When the impeller paddle 22 rotates to release the crop, the rotating impeller paddle 22 drives the rubber rod 24 to collide with the hopper 2 and the guide pipe 3, thereby improving the smoothness of crop discharge.

[0052] The agricultural seeding device can protect the plurality of feeding ports externally provided on the multi-tube shaft disc 4 by using the ring sleeve 31, so as to ensure the stability of the feeding tube 3 and the feeding port when the feeding tube 3 discharges crops, and avoid waste caused by spilling of crops

[0053] Working principle: when it is necessary to adjust the extension pipe 8 to adjust the seeding interval, the operator rotates the distance adjusting screw 5 by using a tool, the rotating distance adjusting screw 5 drives the threaded hinge shaft 6 to retract into the inside of the multi-tube shaft disc 4, and the hinge shaft 6 offsets the expansion support rod 7 to squeeze the hinge-mounted extension pipe 8 to expand, so as to expand the diameter specification of the rubber ring 9, and realize the adjustment of the seeding interval of the extension pipe 8.

[0054] When the operator pushes the expanded rubber ring 9 to perform the seeding operation by holding the handrail frame 1, the rotating multi-tube shaft disc 4 drives the impeller paddle 22 to rotate and feed by the gear shaft 23, and drives the rubber rod 24 to knock the hopper 2 and the feeding tube 3 to accelerate the discharge.
