Description

Technical Field

[0001] The utility model relates to the technical field of forage grass, in particular to an equidistant pit-digging and sowing device for forage grass planting in animal husbandry. Background Technique

[0002] Forage grass is a very important resource in animal husbandry. Planting forage grass can provide rich feed resources and contribute to the healthy development of animal husbandry. At the same time, forage grass planting can improve the ecological environment of pasture land and maintain ecological balance. When planting forage grass in a small area, herdsmen usually use a push-type seeder for manual sowing. For example, the push-type seeder of model NY-5 has a disc-shaped housing, and a number of duckbills are equidistantly arranged on the periphery of the housing. When the push-type seeder sows seeds, a number of duckbills on the periphery of the housing of the push-type seeder will roll along the fluffy soil in turn, forming equidistantly arranged small pits on the fluffy soil, and pre-burying and sowing the forage grass seeds in the housing of the push-type seeder into the above-mentioned small pits in turn.

[0003] As is well known, the number of accurately fed forage grass seeds in the duckbill of the NY-5 type push-type seeder mainly depends on the size of the spherical groove on the periphery of the batching roller. The batching roller is fixedly connected to the housing of the push-type seeder, and the batching roller is rotatably installed at the discharge port of the seed storage. The larger the inner cavity size of the groove, the larger-sized seeds or multiple small-sized seeds can be loaded, while only small-sized forage grass seeds can be loaded into the small-sized inner cavity of the groove. That is, for the existing NY-5 type push-type seeder, when replacing forage grass seeds with a large difference in sowing size, the push-type seeder needs to replace the batching roller adapted to the seed size, and replacing the batching roller also requires disassembling the housing of the push-type seeder, which is troublesome to operate. This article aims to propose a seeder that can change the opening size of the groove of the peripheral batching roller without replacing the batching roller. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when replacing forage grass seeds with a large difference in sowing size in the prior art, the push-type seeder needs to replace the batching roller adapted to the seed size, and replacing the batching roller also requires disassembling the housing of the push-type seeder, and to propose an equidistant pit-digging and sowing device for forage grass planting in animal husbandry.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An equidistant pit-digging and sowing device for forage grass planting in animal husbandry, comprising a plurality of sowing mechanisms. The sowing mechanism includes a disc and a batching box. The disc and the batching roller are coaxially and fixedly connected. The batching roller is rotatably installed in the batching box. A number of large-size grooves are provided on the periphery of the batching roller. An arched block is fitted and installed above the batching roller. The upper surface of the left end of the arched block is provided with an inclined surface that gradually slopes downward. A hole-adjusting plate is horizontally movably arranged on the right side of the arched block. The right end of the hole-adjusting plate slides through the batching box.

[0007] A V-shaped discharge port is arranged on the left side of the hole-adjusting plate. The left end of the hole-adjusting plate is telescopically installed in a telescopic hole in the arched block. An arch frame is fixedly installed on the right side of the batching box. An adjusting bolt is threadedly connected to the arch frame. The left end of the adjusting bolt is rotatably connected to the right end of the hole-adjusting plate.

[0008] Preferably, a rotating roller is arranged in parallel above the batching roller. A number of first bristles are arranged on the periphery of the rotating roller. The first bristles at the lower end of the rotating roller are arranged above the hole-adjusting plate.

[0009] Preferably, a first gear and a second gear that are meshed are arranged between the batching roller and the rotating roller. The first gear is coaxially and fixedly connected to the batching roller. The second gear is coaxially and fixedly connected to the rotating roller.

[0010] Preferably, a seed box is fixedly communicated above the batching box. A discharge pipe is fixedly communicated below the batching box. The end outlet of the discharge pipe is slidably connected to the inner wall of the disc.

[0011] Preferably, a number of perforations are arranged on the periphery of the disc. A number of pit-digging nozzles are fixedly communicated with the periphery of the perforations. The number of pit-digging nozzles corresponds to the number of large-size grooves.

[0012] Preferably, a fixing block is fixedly installed in the telescopic hole. Brush bristles are fixedly installed on both sides of the fixing block. The ends of the brush bristles are in contact with the inner wall of the V-shaped discharge port.

[0013] Compared with the prior art, the utility model provides an equidistant pit-digging and sowing device for forage grass planting in animal husbandry, which has the following beneficial effects:

[0014] 1. The equidistant pit-digging and sowing device for forage grass planting in animal husbandry is provided with an arched block fittingly above the batching roller, and an orifice-adjusting plate for adjusting the inner hole size of the V-shaped discharge port is arranged on the arched block, so that the inner size of the inlet of the large-size groove in the batching roller can be adjusted, thus eliminating the process of removing the housing of the hand-pushed seeder and replacing the batching roller, and the operation is simpler. The specific operation is as follows: by rotating the adjusting bolt on the bow frame counterclockwise or clockwise, the orifice-adjusting plate can be pushed to move left or right along the upper surface of the arched block, so that the size of the hole through which the V-shaped discharge port passes downward through the holes of the forage grass seeds can be adjusted, that is, the size of the hole through which the V-shaped discharge port passes downward through the holes of the forage grass seeds can be adjusted according to the size of the forage grass seeds or the number of forage grass seeds passing through at one time, that is, the inner size of the inlet of the large-size groove in the batching roller can be changed.

[0015] 2. The equidistant pit-digging and sowing device for forage grass planting in animal husbandry is provided with two symmetrically arranged sowing mechanisms, which can sow two rows of forage grass seeds at the same time, and is more stable when placed on the ground. Then, due to the meshing of gear one and gear two, the rotating roller and the disc in the sowing mechanism can rotate synchronously, and the rotating roller and the brush one are driven to rotate clockwise synchronously, so as to sweep the forage grass seeds above the batching box into the V-shaped discharge port at the left end of the orifice-adjusting plate, enabling the sowing mechanism to discharge materials smoothly.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0026] Referring to the attached Figure 1-7 , an equidistant pit-digging and seeding device for forage grass planting in animal husbandry, which relates to a push-type seeding machine with the model NY-5, includes a grip 1. A seed storage box 4 is fixedly installed above the head end of the grip 1. Two seeding mechanisms 3 are symmetrically installed on both sides below the seed storage box 4. The two symmetrically arranged seeding mechanisms 3 can sow two rows of forage grass seeds at the same time, and the ground placement is more stable. A soil-covering roller 2 is rotatably installed below the middle end of the grip 1 through an elastic rubber roller 5. The elastic rubber roller 5 is fixedly connected to the grip 1, and the elastic rubber roller 5 is specifically made of elastic rubber material.

[0027] In this embodiment, the seeding mechanism 3 includes a disc 301, six hole-digging nozzles 303, a seed box 304, a discharge pipe 305, and a batching box 306. The seed box 304 is fixedly communicated above the batching box 306. The lower part of the seed storage box 4 is fixedly communicated with the upper parts of the seed boxes 304 in the two seeding mechanisms respectively. That is, the forage grass seeds loaded in the seed storage box 4 can flow into the seed boxes 304 in the two seeding mechanisms. Six perforations 302 are evenly distributed on the periphery of the disc 301. Six hole-digging nozzles 303 are respectively fixedly installed on the peripheries of the six perforations 302 on the periphery of the disc 301, and the inner size of the hole-digging nozzle 303 is larger than the inner size of the perforation 302. That is, the seeds in the perforation 302 can smoothly enter the hole-digging nozzle 303. The end of the hole-digging nozzle 303 is provided with an inclined pointed head for smoothly inserting into the fluffy soil body. The batching box 306 is rotatably arranged on the central axis of the inner cavity of the disc 301. The lower part of the batching box 306 is fixedly communicated with the upper end of the discharge pipe 305. The lower discharge port of the discharge pipe 305 is in contact sliding connection with the inner wall of the disc 301. That is, the discharge port of the discharge pipe 305 can rotate in a sealed manner along the inner wall of the disc 301. The inner size of the discharge port of the discharge pipe 305 is smaller than the inner size of the perforation 302, so that the seeds in the discharge pipe 305 can smoothly enter the perforation 302.

[0028] In this embodiment, a batching roller 307 is rotatably installed in the batching box 306. The batching roller 307 is in a cylindrical shape as a whole. One end of the batching roller 307 is fixedly connected coaxially with the disc 301. Six large-sized grooves 316 are evenly distributed on the periphery of the batching roller 307. An arched block 308 is fixedly connected to the upper end of the batching roller 307. The lower part of the arched block 308 coincides with the upper part of the batching roller 307. An inclined surface for guiding the seeds to flow to the middle of the upper surface of the arched block 308 is arranged above the left side of the arched block 308. The upper surface of the inclined surface gradually slopes downward from left to right. A hole-adjusting plate 309 is horizontally slidably installed on the upper surface of the right side of the arched block 308. A V-shaped discharge port 310 is arranged on the left side of the hole-adjusting plate 309. The left end of the V-shaped discharge port 310 is telescopically installed in the telescopic hole in the arched block 308. By moving the position of the hole-adjusting plate 309 left and right, the size of the V-shaped discharge port 310 passing through the holes of the forage grass seeds downward can be adjusted;

[0029] The right end of the orifice plate 309 slides out of the batching box 306. A bow-shaped bracket 314 is fixedly installed on the right side wall of the batching box 306. An adjusting bolt 313 is threadedly connected to the bow-shaped bracket 314. The left end of the adjusting bolt 313 is rotatably connected to the right end face of the orifice plate 309. The inner width of the V-shaped discharge port 310 gradually decreases from left to right, so that the expansion hole between the orifice plate 309 and the arched block 308. The inner height of the expansion hole in the arched block 308 is smaller than the size of general forage seeds, that is, the forage seeds will not enter the expansion hole. Also, the thickness of the orifice plate 309 is smaller than the size of the forage seeds. However, impurities mixed in the forage seeds may still enter the expansion hole. And because the inner width of the V-shaped discharge port 310 gradually decreases from left to right, generally the left end of the V-shaped discharge port 310 cannot block the opening of the expansion hole in the arched block 308, that is, impurities are likely to enter through the opening of the expansion hole. For this reason, a fixing block 320 is fixedly installed in the middle of the expansion hole. Brush hairs two 321 are fixedly installed on both side end faces of the fixing block 320. The brush hairs two 321 are made of elastic plastic filaments. The ends of the brush hairs two 321 are in pressing contact with the inner wall of the V-shaped discharge port 310. The brush hairs two 321 made of elastic plastic filaments are mainly used to elastically block the expansion hole, so as to ensure that impurities will not enter the expansion hole and ensure the cleanliness of the inner cavity of the expansion hole.

[0030] In this embodiment, a roller 311 is arranged at the upper end of the orifice plate 309. Brush hairs one 312 are fixedly installed on the periphery of the roller 311. The brush hairs one 312 at the lower end of the roller 311 are in contact with and close to the upper surface of the orifice plate 309. And the roller 311 is slightly offset to the right of the V-shaped discharge port 310. When the roller 311 rotates clockwise on the upper surface of the orifice plate 309, the roller 311 can drive the brush hairs one 312 thereon to sweep the forage seeds in the batching box 306 into the V-shaped discharge port 310 in the orifice plate 309.

[0031] The rollers 311 are arranged in parallel above the same vertical plane of the batching roller 307. A gear one 317 and a gear two 318 that mesh with each other are arranged on one side of the batching roller 307 and the roller 311. The gear one 317 is coaxially and fixedly connected to the batching roller 307. The gear two 318 is coaxially and fixedly connected to the roller 311. An arc-shaped block 315 is fixedly installed at the lower right of the batching box 306. The arc-shaped block 315 fits with the lower right of the batching roller 307. Six large-size grooves 316, six through holes 302 and six digging nozzles 303 correspond to each other. And the connecting lines of the six large-size grooves 316, six through holes 302 and six digging nozzles 303 are evenly arranged at six radial positions of the disc 301.

[0032] For the present utility model, when the equidistant pit-digging and seeding device for forage grass planting in animal husbandry is in use, the grip 1 is used to push the two seeding mechanisms 3 to move along the fluffy soil body. The discs 301 in the two seeding mechanisms 3 will rotate along the lower fluffy soil body for equidistant seeding. The six pit-digging nozzles 303 on the rotating seeding mechanism 3 will sequentially and equidistantly insert into the fluffy soil body as the equidistant pit-digging and seeding device for forage grass planting in animal husbandry moves. When the pit-digging nozzle 303 inserts into the fluffy soil body, a small pit will be dug, and the forage grass seeds in the seeding mechanism 3 will be sown into the small pit. Then, as the equidistant pit-digging and seeding device for forage grass planting in animal husbandry moves, the soil covering roller 2 will push the soil to cover the small pit dug by the seeding mechanism 3, so as to bury the seeds in the small pit in the soil body;

[0033] As Figure 5-6 , when the two seeding mechanisms 3 rotate clockwise, the forage grass seeds in the seed box 304 will automatically fall onto the orifice plate 309, and the rotating disc 301 will drive the batching roller 307 to rotate counterclockwise in the batching box 306. Then, the gear one 317 and the gear two 318 that mesh with each other will synchronously drive the roller 311 and the brush one 312 to rotate clockwise, which is used to sweep the forage grass seeds above the batching box 306 into the V-shaped discharge port 310 at the left end of the orifice plate 309. Then, as the disc 301 and the batching roller 307 rotate 60° each time, the forage grass seeds entering the V-shaped discharge port 310 will sequentially fall into the six large-sized grooves 316 in the batching roller 307. And as the forage grass seeds in the six large-sized grooves 316 rotate clockwise with the batching roller 307, the lowermost large-sized groove 316 will sequentially fall into the discharge pipe 305. That is, each time the seeding mechanism 3 rotates 60°, one forage grass seed will fall into the batching roller 307 and one forage grass seed will be discharged downward. The forage grass seeds in the discharge pipe 305 will fall to the discharge port below the discharge pipe 305 by their own weight. And when the discharge pipe 305 and the pit-digging nozzle 303 are aligned and communicated, the forage grass seeds at the end of the discharge pipe 305 can enter the pit-digging nozzle 303 through the perforation 302. Because when the grip 1 is held by hand, the end of the discharge pipe 305 is arranged downward, that is, only when the pit-digging nozzle 303 rotates downward can the forage grass seeds be discharged, so as to realize the equidistant pit-digging and seeding of forage grass seeds;

[0034] In this application, the adjusting bolt 313 on the bow-shaped frame 314 can also be rotated counterclockwise or clockwise, so that the adjusting bolt 313 can push the orifice plate 309 to move left or right along the upper surface of the arched block 308, thereby adjusting the size of the hole through which the V-shaped discharge port 310 passes downward through the forage grass seeds. That is, the size of the hole through which the V-shaped discharge port 310 passes downward through the forage grass seeds can be adjusted according to the size of the forage grass seeds.

[0035] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
