A seed-spreading device for vegetable cultivation

Abstract

This utility model discloses a seed-spreading device for vegetable planting, comprising: a base plate with a moving mechanism on the base plate; a seed box fixedly installed on the top of the base plate with a funnel-shaped bottom end passing through the base plate; a fixed cylinder fixedly installed at the bottom of the seed box; and a rotating rod rotatably connected to one end of the fixed cylinder, with a transmission mechanism between the rotating rod and the moving mechanism. By rotating the screw, a circular block is driven to move closer to the rotating roller, causing the clearance groove on the circular block to slide in cooperation with the rotating roller. This allows the circular block to block the receiving groove on the rotating roller, thereby reducing the volume of the receiving groove. Conversely, reversing the screw increases the volume. Thus, the volume of the receiving groove of the rotating roller can be adjusted, facilitating flexible control according to different types of seeds and effectively improving the flexibility and applicability of vegetable planting.

Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, specifically to a seed sowing device for vegetable planting. Background Technology

[0002] Vegetables refer to a class of plants or fungi that can be cooked and eaten. Vegetables are an essential part of people's daily diet. Vegetables provide the human body with a variety of essential vitamins and minerals.

[0003] A known authorized patent with publication number CN221930633U discloses a mobile vegetable planting and sowing device. Its background art addresses the problem that "the length of the material discharge pipe cannot be adjusted during use. When sowing in fields with different heights and furrows, the height of the plow hook cannot be adjusted, easily leading to shallow furrows and affecting seed growth." The proposed solution is as follows: "It includes a support frame, moving wheels, a cylinder, and a hopper. The cylinder has a rotating rod and a rotating roller inside. A belt connects the rotating roller and the moving wheels. The bottom of the cylinder has a material discharge pipe, and the outside of the material discharge pipe has a lifting pipe. The bottom of the lifting pipe has a plow hook. A lifting assembly connects the support frame and the lifting pipe. The upper end of the support frame has a control box, a push handle, and control buttons."

[0004] However, in implementing the relevant technology, the following problems were found in the above technical solution: it is inconvenient to adjust the volume of the roller groove during use. The volume of the roller groove is fixed, which makes it difficult to control the quantitative discharge of seeds, making it difficult to apply to different types of vegetable seeds. In addition, it is inconvenient to disperse the falling seeds, which can easily cause the falling seeds to accumulate and affect planting, thus reducing the flexibility and effectiveness of planting. Utility Model Content

[0005] This invention proposes a seed sowing device for vegetable planting, which solves the problems in related technologies such as the inconvenience of adjusting the volume of the rotating roller groove and the inconvenience of dispersing the falling seeds.

[0006] The technical solution of this utility model is as follows: A seed sowing device for vegetable planting, comprising: a base plate, wherein a moving mechanism is provided on the base plate; A seed box that is fixedly installed on the top of a base plate and has a funnel-shaped bottom that passes through the base plate; A fixing cylinder that is fixedly installed at the bottom of the seed box; A rotating rod is rotatably connected to one end of a fixed cylinder, and a transmission mechanism is provided between the rotating rod and the moving mechanism; A rotating roller is fixedly connected to one end of a rotating rod and located inside a fixed cylinder, and the surface of the rotating roller is provided with multiple receiving grooves. A rotating screw that is threaded through to the other end of the fixed cylinder; A circular block is rotatably connected to one end of a rotating screw and located inside a fixed cylinder. One end face of the circular block is provided with multiple clearance grooves that slide in cooperation with the rotating roller. And a feeding pipe fixedly installed at the bottom of the surface of the fixed cylinder, wherein the feeding pipe is provided with a dispersing mechanism to separate the seeds.

[0007] Preferably, the transmission mechanism includes a fixed block fixedly installed on the bottom surface of the seed box, a first pulley fixedly connected to the other end of the rotating rod, a second pulley provided on the moving mechanism, and a transmission belt tensioned and connected to the surfaces of the second pulley and the first pulley. The fixed block and the rotating rod are rotatably connected.

[0008] Preferably, the dispersing mechanism includes a dispersing column disposed inside the feed pipe, and a plurality of baffles fixedly installed on the surface of the dispersing column, wherein the plurality of baffles are all connected to the feed pipe, and the top of the dispersing column is conical.

[0009] Preferably, the moving mechanism includes two moving wheels rotatably connected to the bottom of the base plate, two push rods fixedly installed on one side of the base plate, and a support rod rotatably connected to the bottom of the push rods via a damping shaft, with the second pulley fixedly installed on one end face of one of the moving wheels.

[0010] Preferably, the bottom of the base plate is provided with a trenching mechanism for planting.

[0011] The trenching mechanism includes a hollow block fixedly installed at the bottom of the base plate, a movable block slidably connected inside the hollow block, a hand-tightening bolt threaded to one side of the hollow block and in contact with the movable block, and a trencher fixedly installed at the bottom of the movable block.

[0012] Preferably, the seed box is provided with an expansion mechanism for increasing its volume.

[0013] The expansion mechanism includes an expansion box that is slidably connected inside the seed box and has open top and bottom ends, a mounting block that is fixedly installed on the bottom of one side of the seed box, a concave block that is fixedly installed on the top of one side of the seed box, a lead screw that is rotatably connected between the concave block and the mounting block, and a Z-shaped plate that is threaded to the surface of the lead screw and slides with the concave block. One end of the Z-shaped plate is connected to the expansion box, and one end of the lead screw moves through the mounting block and is connected to a rotating block.

[0014] The working principle and beneficial effects of this utility model are as follows: 1. By using a moving mechanism in conjunction with a transmission mechanism, a rotating rod can drive a rotating roller to rotate, allowing seeds in the seed box to fall quantitatively for planting. When different types of seeds require adjustment of the quantitative amount, rotating the rotating screw causes a circular block to move closer to the rotating roller. This allows the clearance groove on the circular block to slide in conjunction with the rotating roller, thus blocking the receiving groove on the rotating roller and reducing its volume. Conversely, reversing the screw increases the volume. Therefore, this achieves the effect of adjusting the volume of the rotating roller's receiving groove, avoiding the situation where the quantitative amount cannot be adjusted and has poor applicability. It facilitates flexible control according to different types of seeds, effectively improving the flexibility and applicability of vegetable planting.

[0015] Second, when the seeds fall through the feeding pipe, the cone-shaped surface of the dispersing column guides the seeds, causing them to disperse and flow into the gaps between multiple partitions. This disperses the seeds and allows them to flow out from each gap, thus keeping the falling seeds in a dispersed state and preventing them from accumulating and causing adverse effects, which is beneficial to improving the planting effect.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1 Please see Figure 1 - Figure 5 The present invention provides a seed sowing device for vegetable planting, comprising: a base plate 1, on which a moving mechanism is provided; Seed box 3 is fixedly installed on the top of the base plate 1, with a funnel-shaped bottom end and passing through the base plate 1; The fixing cylinder 4 is fixedly installed at the bottom of the seed box 3; A rotating rod 6 is rotatably connected to one end of the fixed cylinder 4, and a transmission mechanism is provided between the rotating rod 6 and the moving mechanism; A rotating roller 7 is fixedly connected to one end of the rotating rod 6 and located inside the fixed cylinder 4. The surface of the rotating roller 7 is provided with multiple receiving grooves. A rotating screw 8 is threadedly connected to the other end of the fixed cylinder 4; A circular block 9 is rotatably connected to one end of the rotating screw 8 and located inside the fixed cylinder 4. One end face of the circular block 9 is provided with multiple clearance grooves that cooperate with the rotating roller 7 to slide. And a feeding pipe 10 fixedly installed at the bottom of the surface of the fixed cylinder 4, the feeding pipe 10 being provided with a dispersing mechanism to separate the seeds.

[0021] The transmission mechanism includes a fixed block 5 fixedly installed on the bottom surface of the seed box 3, a pulley 11 fixedly connected to the other end of the rotating rod 6, a pulley 12 provided on the moving mechanism, and a transmission belt 13 tensioned and connected to the surfaces of the pulley 12 and the pulley 11. The fixed block 5 and the rotating rod 6 are rotatably connected.

[0022] The technical solution provided in this embodiment is as follows: During use, seeds are temporarily stored in the seed box 3. The base plate 1 moves at a constant speed through a moving mechanism. During this process, the moving mechanism drives the pulley 12 to rotate, and the pulley 11 rotates synchronously through the transmission belt 13. This causes the rotating rod 6 to drive the rotating roller 7 to rotate, so that the seeds in the seed box 3 sequentially and quantitatively enter the receiving groove on the rotating roller 7. When the receiving groove of the rotating roller 7 is aligned with the feeding pipe 10, the seeds in the receiving groove fall and are discharged. This facilitates quantitative seed falling for planting. The falling seeds are dispersed by a dispersing mechanism to prevent seed aggregation and accumulation from affecting the planting efficiency. When different types of seeds require adjustment of the quantitative size, rotating the screw 8 causes the circular block 9 to move closer to the rotating roller 7. This allows the clearance groove on the circular block 9 to slide in conjunction with the rotating roller 7, thus blocking the receiving groove on the rotating roller 7 and reducing its volume. Conversely, rotating the screw 8 in reverse increases the volume. This achieves the effect of adjusting the volume of the receiving groove on the rotating roller 7, avoiding the situation where the quantitative size cannot be adjusted and has poor applicability. It facilitates flexible control according to different types of seeds, effectively improving the flexibility and applicability of vegetable planting.

[0023] It should be noted that during the initial planting, the rotating roller 7 can be rotated first to move the first seed-filled container to be aligned with the feed pipe 10, so as to avoid the situation where the seeds cannot fall at the beginning of the planting stage.

[0024] Furthermore, the dispersing mechanism includes a dispersing column 14 disposed inside the feed pipe 10, and a plurality of baffles 15 fixedly installed on the surface of the dispersing column 14. The plurality of baffles 15 are all connected to the feed pipe 10, and the top of the dispersing column 14 is conical.

[0025] Specifically, when the seeds fall through the feed pipe 10, the cone-shaped surface of the dispersion column 14 guides the seeds, causing them to disperse and flow into the gaps between multiple partitions 15. This disperses the seeds and allows them to flow out from each gap, thus keeping the falling seeds in a dispersed state and preventing them from accumulating and causing adverse effects, which is beneficial to improving the planting effect.

[0026] Furthermore, the moving mechanism includes two moving wheels 2 rotatably connected to the bottom of the base plate 1, two push levers 20 fixedly installed on one side of the base plate 1, and a support rod 21 rotatably connected to the bottom of the push lever 20 via a damping shaft. A pulley 2 12 is fixedly installed on one end face of one of the moving wheels 2.

[0027] Specifically, by holding the push handle 20 and using the moving wheels 2, the base plate 1 can be moved for planting. At the same time, the support rod 21 is rotated to extend from the push handle 20, which can support the base plate 1.

[0028] Furthermore, the bottom of the base plate 1 is provided with a trenching mechanism for planting.

[0029] The trenching mechanism includes a hollow block 16 fixedly installed at the bottom of the base plate 1, a movable block 17 slidably connected inside the hollow block 16, a hand-tightening bolt 18 threadedly connected to one side of the hollow block 16 and in contact with the movable block 17, and a trencher 19 fixedly installed at the bottom of the movable block 17.

[0030] Specifically, by setting up the furrow opener 19, planting furrows can be plowed out, making it convenient for seeds to fall into the furrows for planting. By loosening the hand-tightening bolt 18, the movable block 17 can be moved up and down to slide within the hollow block 16 to adjust its height, thereby moving the furrow opener 19 and adjusting its distance from the ground. This allows for easy adjustment according to needs and facilitates adjustment of the furrow depth.

[0031] Example 2 Based on Example 1, in this example: the seed box 3 is provided with an expansion mechanism for increasing the volume.

[0032] The expansion mechanism includes an expansion box 22 that is slidably connected inside the seed box 3 and has open top and bottom ends, a mounting block 23 that is fixedly installed on the bottom of one side of the seed box 3, a concave block 24 that is fixedly installed on the top of one side of the seed box 3, a lead screw 25 that is rotatably connected between the concave block 24 and the mounting block 23, and a Z-shaped plate 26 that is threadedly connected to the surface of the lead screw 25 and slides with the concave block 24. One end of the Z-shaped plate 26 is connected to the expansion box 22, and one end of the lead screw 25 moves through the mounting block 23 and is connected to a rotating block.

[0033] The technical solution provided in this embodiment is as follows: When the planting area is large and the seed loading capacity needs to be increased, the rotating block drives the lead screw 25 to rotate, so that the lead screw 25 drives the Z-shaped plate 26 to slide upward along the concave block 24, thereby driving the expansion box 22 to move upward, so that the expansion box 22 and the seed box 3 cooperate to store the seeds, thereby increasing the storage capacity of the seed box 3, which makes it easier to increase the amount of seeds loaded at one time and helps to reduce the frequency of adding seeds.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
