Description

Technical Field

[0002] Camellia oleifera, also known as common camellia, wild camellia, mountain camellia, and single-seed camellia, is an evergreen shrub or tree of the genus Camellia in the family Theaceae. The crown is spherical or ovoid, the bark is smooth, yellow-brown; the leaves are leathery, elliptical, oblong or obovate. The flowers are terminal, nearly sessile, with white petals, 5 to 7 petals. The capsule is spherical or ovoid. The flowering period is from October to February of the following year, and the fruiting period is from September to October of the following year.

[0003] Before sowing oil tea, the planting field needs to be prepared, and when sowing, an oil tea planting, sowing and fertilizing machine is needed.

[0004] During operation, existing seeders often rely on slotters to first dig the soil to form a sowing furrow, and then place fertilizers and seeds along the furrow at intervals. However, this traditional method has significant disadvantages: first, the distribution of seeds and fertilizers is too dense, resulting in uneven nutrient distribution and greatly reduced fertilizer utilization; second, the sowing depth control is not accurate, resulting in uneven seed depth, which directly affects the germination rate and uniformity of seedlings, and then causes the problem of uneven emergence time; in addition, in the subsequent burying process, seeds are prone to position displacement, and it is difficult to ensure a reasonable spacing between seeds, which has an adverse effect on the later growth density and yield of crops.

[0058] Preferably, a protective cover for protecting the pulley and the belt is installed on one side of the body 11.

[0059] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the feeding unit 20 includes a first shaft 21 rotatably connected to the body 11, and a plurality of feed levers 22 are mounted on the first shaft 21. A plurality of discharge ports are provided on one side wall of the first fertilizer chamber, the second fertilizer chamber 15 and the third fertilizer chamber, and a fertilizer transfer box 23 is fixedly connected to the discharge port. A fertilizer lower slide groove is provided on one side of the inner bottom wall of the fertilizer transfer box 23, and a fertilizer conveying pipe 24 is fixed in the fertilizer lower slide groove.

[0060] Two seed outlets are provided on one side wall of the first seed cavity and the second seed cavity 16 , and a seed transfer box 25 is fixedly connected to the seed outlet. A seed sliding groove is provided on one side of the bottom wall of the seed transfer box 25 , and a seed conveying pipe 26 is installed in the seed transfer box 25 .

[0061] A support member is fixed to the bottom of the fertilizer transfer box 23 and the seed transfer box 25 . Both ends of the support member are fixed to the fuselage 11 . The support member is used to support the fertilizer transfer box 23 and the seed transfer box 25 .

[0062] A feeding round seat 27 is rotatably provided in the fertilizer transfer box 23, a storage cavity is provided in the feeding round seat 27, and a feeding groove corresponding to the discharge port is provided on one side wall of the storage cavity; a seed feeding round seat 28 is rotatably connected in the seed transfer box 25, a seed feeding round seat 28 is provided with a seed storage cavity, and a seed feeding groove corresponding to the discharge port is provided on one side wall of the seed storage cavity.

[0063] A second shaft rod 29 is fixed to both the material feeding round seat 27 and the seed feeding round seat 28 , and both ends of the second shaft rod 29 are rotatably connected to the machine body 11 .

[0064] A first pulley is fixed to one end of the second shaft 29 that passes through the fuselage 11, and a double-groove pulley 210 that matches the first pulley is fixed to one end of the first shaft 21 that passes through the fuselage 11. A second pulley that matches the double-groove pulley is fixedly sleeved on one of the main shafts 12, and two transmission belts 211 are mounted on the double-groove pulley 210. The double-groove pulley 210 is respectively connected to the first pulley and the second pulley through the two transmission belts 211.

[0065] Specifically, the inner cavities of the fertilizer transfer box 23 and the seed transfer box 25 are both arc-shaped, and are respectively fitted with the feeding round seat 27 and the seed feeding round seat 28. The storage cavity can only store a fixed amount of fertilizer, and the seed storage cavity can only store one seed. The first shaft 21 drives the material shifting rod 22 to rotate, and then the material shifting rod 22 shifts the fertilizer into the storage cavity in the fertilizer cavity. After the storage cavity is full of fertilizer, the material shifting rod 22 cannot shift more fertilizer into the storage cavity. When the material shifting rod 22 shifts seeds in the seed storage cavity, after shifting one seed into the seed storage cavity, no more seeds can be shifted into the seed storage cavity.

[0066] At the same time, during the clockwise rotation of the feeding round seat 27, the feeding trough on the feeding round seat 27 rotates to be connected with the fertilizer lower sliding trough on the inner bottom wall of the fertilizer transfer box 23. At this time, the fertilizer in the storage cavity will fall completely and enter the fertilization plate through the fertilizer conveying pipe 24, thereby completing the fertilization.

[0067] At the same time, during the clockwise rotation of the seed delivery circular seat 28, the seed feeding groove on the seed delivery circular seat 28 rotates to be connected with the seed lower sliding groove on the inner bottom wall of the seed transfer box 25. At this time, the seeds in the seed storage cavity will fall and fall into the sowing groove 426 in the sowing plate 421 through the seed conveying tube 26, and then be sown in the soil.

[0068] During the rotation of the feeding round seat 27 and the seeding round seat 28, the outer walls of the feeding round seat 27 and the seeding round seat 28 gradually close the material outlet on the inner wall of the fertilizer cavity and the seed outlet on the inner wall of the seed cavity respectively.

[0069] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the frame 30 includes a protective shell 31, on which is mounted an upper protective cover 33 for cooperating to protect the fertilizer delivery pipe 24 and the seed delivery pipe 26. Mounting parts 32 are fixed at the edges of both sides of the fuselage 11, one side of the mounting parts 32 is fixed to the protective shell 31, and one side of the protective shell 31 is provided with a plurality of through holes adapted to the fertilizer delivery pipe 24 and the seed delivery pipe 26.

[0070] An extension piece 34 is fixed to one end of the mounting piece 32 , and mounting clips 35 are fixed to the ends of the two extension pieces 34 . The mounting clips 35 are bolted with fixing studs, and a corrugated plate 36 is assembled in the mounting clips 35 through the fixing studs.

[0071] The protective shell 31 cooperates with the upper protective cover 33 to shield and protect the fertilizer delivery pipe 24 and the seed delivery pipe 26, and both the protective shell 31 and the upper protective cover 33 can be disassembled. At the same time, after sowing and fertilizing, the corrugated plate 36 located at the rear can scrape the surface of each ridge of soil to a relatively horizontal state, so that the seeds can be at the same depth.

[0072] like Figure 1 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, the layered spreading unit 40 includes a ridging assembly 41 , and a spreading assembly 42 is mounted inside the ridging assembly 41 .

[0073] The sowing assembly 42 includes a lower fertilization plate 423, a middle fertilization plate 422 is provided on the lower fertilization plate 423, a sowing plate 421 is provided on the middle fertilization plate 422, a seeding tube 425 is fixedly connected to the middle of the upper surface of the sowing plate 421, and a surface fertilization plate 424 is mounted on the outer wall of the seeding tube 425.

[0074] The ridging component 41 digs furrows and ridges the land after rotary tillage as the machine body 10 moves forward. During the process, the seeding plate 421, the middle fertilizer plate 422 and the lower fertilizer plate 423 extend into the soil of each ridge and move, and the surface fertilizer plate 424 moves on the soil surface. During the movement, oil tea seeds and fertilizers are intermittently fed into the seeding plate 421, the middle fertilizer plate 422, the lower fertilizer plate 423 and the surface fertilizer plate 424 through the feeding unit 20, and the seeds and fertilizers are distributed on the same axis.

[0075] like Figure 1 , Figure 2 , Figure 3 and Fig.12 As shown, the ridging assembly 41 includes a furrowing member 411, and a slope protection member 412 is integrally formed at one end of the furrowing member 411, wherein a first connecting member 413 and a second connecting member 414 are fixed to the two slope protection members 412, and the first connecting member 413 and the second connecting member 414 are fixed to the extension member 34 by bolts.

[0077] Specifically, during the process of moving, the trenching member 411 can be used to trench the prepared land, and the trench wall can be shaped by the slope protection member 412, so that the land is divided into ridges.

[0078] like Figure 1 , Figure 2 , Figure 3 and Fig.12 As shown, a sowing groove 426 connected to the seed inlet pipe 425 is opened in the middle of the lower surface of the sowing plate 421, and the seed conveying pipe 26 is fixedly connected to the seed inlet pipe 425.

[0079] A surface fertilization cavity 427 is opened at the midline of the lower surface of the surface fertilization plate 424, and a plurality of first connecting rods are fixed to the bottom of the inner wall of the surface fertilization cavity 427, and a surface material distribution cone 428 for spreading fertilizer in a ring shape on the surface of each ridge of soil is fixed to the other ends of the plurality of first connecting rods. Arc-shaped material guide pipes 429 are fixed on both sides of the upper surface of the surface fertilization plate 424, and a shunt pipe 4210 is fixedly connected to the arc-shaped material guide pipe 429, and one end of one of the fertilizer conveying pipes 24 is fixedly connected to the two shunt pipes 4210.

[0080] A middle-layer fertilization chamber 4211 is provided at the center of the lower surface of the middle-layer fertilization plate 422, and a middle-extension groove is provided on one side wall of the middle-layer fertilization chamber 4211. The inner diameter of the middle-layer fertilization chamber 4211 is larger than that of the surface-layer fertilization chamber 427. A plurality of second connecting rods are fixed to the bottom of the inner wall of the middle-layer fertilization chamber 4211, and a middle-layer material dividing cone 4212 for making the fertilizer fall in a ring shape to the middle layer of each ridge of soil is fixed at the other ends of the plurality of second connecting rods. A middle-layer connecting pipe 4213 is fixedly connected to the middle part of the upper surface of the middle-layer fertilization plate 422, and one end of the middle-layer connecting pipe 4213 is fixedly connected to one end of the fertilizer conveying pipe 24, and the middle-layer connecting pipe 4213 is fixed to the surface-layer fertilization plate 424.

[0081] A lower fertilization chamber 4214 is provided at the center of the lower surface of the lower fertilization plate 423, a lower extension groove is provided on one side wall of the lower fertilization chamber 4214, the inner diameter of the lower fertilization chamber 4214 is larger than that of the middle fertilization chamber 4211, a plurality of third connecting rods are fixed to the bottom of the inner wall of the lower fertilization chamber 4214, a lower material dividing cone 4215 for making the fertilizer fall in a ring shape to the lower layer of each ridge of soil is fixedly provided at the other ends of the plurality of third connecting rods, a lower connecting pipe 4216 is fixedly connected to the middle part of the upper surface of the lower fertilization plate 423, one end of the lower connecting pipe 4216 is fixedly connected to one end of the fertilizer conveying pipe 24, and the lower connecting pipe 4216 is fixed to the surface fertilization plate 424 of the middle fertilization chamber 4211.

[0082] The sowing plate 421, the middle fertilizing plate 422 and the lower fertilizing plate 423 are all corrugated.

[0083] Specifically, during sowing and fertilizing, the fertilizer applied to the surface layer of the soil in each ridge through the surface fertilizer plate 424, the seeds sown in the upper layer of the soil in each ridge through the sowing plate 421, the fertilizer applied to the middle layer of the soil in each ridge through the middle fertilizer plate 422, and the fertilizer applied to the lower layer of the soil in each ridge through the lower fertilizer plate 423 are all on the same axis, and the surface fertilizer, middle fertilizer and lower fertilizer are dispersed in a cone shape as a whole, so that after the seeds take root, they can get good nutrients during the process of root growth and dispersion.

[0084] Specifically, when the oil-tea planting, sowing and fertilizing machine is working / in use:

[0085] First, the fuselage 11 is connected to the agricultural machine through the connecting frame 17, and then the seeds and fertilizers are loaded into the seed cavity and the fertilizer cavity respectively. Then, the agricultural machine drives the fuselage 11 to move on the prepared plot. During the movement, the ditching member 411 moves on the plot to ditch the prepared plot. At the same time, the rear slope protection member 412 shapes the ditch wall so that the plot is divided into ridges. At the same time, during the ridge forming process, the surface fertilizer plate 424 is located on the surface of each ridge soil and moves, the seeding plate 421 penetrates into the upper layer of each ridge soil to move, the middle layer fertilizer plate 422 penetrates into the middle layer of each ridge soil to move, and the lower layer fertilizer plate 423 penetrates into the lower layer of each ridge soil to move. During the movement, the corrugated seeding plate 421, the middle layer fertilizer plate 422 and the lower layer fertilizer plate 423 can make the prepared plot soil more loose, making the soil more suitable for the growth of tea seeds.

[0086] At the same time, during the movement, the walking wheel 13 drives the main shaft 12 to rotate, so that the second pulley rotates synchronously, and under the action of the transmission belt 211, the double-groove pulley 210 drives the first shaft 21 to rotate. The rotation of the first shaft 21 will drive the material removal rod 22 to rotate, and then the seeds and fertilizers in the seed cavity and the fertilizer cavity are respectively sent into the seed delivery round seat 28 and the material delivery round seat 27.

[0087] When the second pulley rotates, the first pulley is driven to rotate through the transmission belt 211, so that the second shaft rod 29 rotates. When the second shaft rod 29 rotates, the seed feeding round seat 28 and the material feeding round seat 27 are driven to rotate.

[0088] When the seed feeding groove on the seed delivery round seat 28 rotates to be connected with the seed lower sliding groove on the inner bottom wall of the seed transfer box 25, the seeds in the seed storage cavity fall down and fall into the sowing groove 426 in the sowing plate 421 through the seed conveying pipe 26, and then are sown on the soil below the sowing groove 426.

[0089] When the feeding chute on the feeding round seat 27 rotates to be connected with the fertilizer lower sliding chute on the inner bottom wall of the fertilizer transfer box 23, the fertilizer in the storage chamber will fall completely and enter the surface fertilization plate 424, the middle fertilization plate 422 and the lower fertilization plate 423 through the fertilizer conveying pipe 24, and under the action of the surface material dividing cone 428, the middle material dividing cone 4212 and the lower material dividing cone 4215, the fertilizer is spread in a ring shape on the surface, middle and lower layers of the soil, and the spreading range gradually increases. After sowing and fertilizing, the upper layer of soil blocked by the sowing plate 421 will fall directly during the forward movement of the plate body and cover the surface of the seeds, which will not drive the seeds to shift. Similarly, the middle layer of soil will cover the surface of the fertilizer applied in the middle layer, and the lower layer of soil will cover the surface of the fertilizer applied in the lower layer.

[0090] During the movement, the rear corrugated paddle 36 is in a horizontal state, which will drive the surface soil of each ridge to a relatively horizontal state, thereby ensuring the consistency of the seed planting depth.
