Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a dual-purpose box for sowing and fertilizing. Background Art

[0002] The sowing and fertilizing device is an agricultural machine often used in agricultural production, and the sowing and fertilizing box is a delivery mechanism that must be equipped with the sowing and fertilizing device. The seeds or fertilizers are delivered on demand through the control of the sowing and fertilizing box. Conventional sowing and fertilizing boxes generally include a roller with flower teeth arranged in a shell, and the roller rotates under the drive of a motor, thereby driving the seeds or fertilizers to be discharged from the outlet of the shell, and finally achieving the purpose of delivery.

[0003] For example, the "fertilizer box for planter" disclosed in the Chinese utility model patent with application number 200720194911.8 (authorization announcement number CN201104400Y) includes a housing, a flower tooth, and a gland component. The housing is provided with a plurality of bosses, and a retaining pad and a gland are installed on the bosses by screws. A rotatable flower tooth is installed between the retaining pad and the gland, and one end of the flower tooth is flush with the inner plane of the housing, and the other end is flush with the outer plane of the gland. The fertilizer box for planter has the advantages of simple structure, easy and convenient rotation of the flower tooth, and long service life.

[0004] For example, the Chinese utility model patent with application number 202023255236.X (authorization announcement number CN214708689U) discloses an integrated electric fertilizer box, which includes a motor. The ends of the motor are fixedly mounted inside a motor fixing seat. A fertilizer box drum is sleeved on the middle part of the motor. The end of the output shaft of the motor is connected to the inner wall of the driving hub, and the outer wall of the driving hub is connected to the inner wall of the end of the fertilizer box drum. The motor fixing seat, the fertilizer box drum and the outside of the driving hub are fixedly connected to the upper shell and the bottom shell. The integrated fertilizer box can reduce the volume of the fertilizer box, has a compact structure, and is also easier to install.

[0005] However, there is a common problem in the above-disclosed prior art. The seeds or fertilizers are fed through a channel formed by the interval between the outer surface of the drum and the inner wall of the shell. Due to structural reasons, the size of the channel in this area is generally not adjustable. When encountering some larger seeds, the seeds passing through the channel may be blocked, crushed or crushed, thereby affecting subsequent use.

[0006] Therefore, how to provide a sowing and fertilizing box that can realize extrusion buffering in the feeding channel through which seeds or fertilizers pass, so that the discharge of seeds or fertilizers can be smoother and can avoid the crushing or crushing of seeds, is a problem that technical personnel in this field urgently need to solve.

[0007] In addition, due to the limitation of the drum structure, the existing sowing and fertilizing boxes generally cannot take into account both sowing and fertilizing, and can only perform sowing or only perform fertilization. Utility Model Content

[0013] In order to optimize the overall structure of the adjusting device so that it can lock the tongue plate more conveniently, preferably, the adjusting device includes an adjusting pin, and the shell is provided with a plurality of adjusting holes arranged up and down. When the tongue plate is rotated to a set position, the adjusting pin is passed through the corresponding adjusting hole to limit the tongue plate from continuing to rotate downward so as to complete the adjustment of the tongue plate.

[0014] In order to make sowing and fertilizing more accurate, preferably, the hobbing forms a first tooth wall inclined toward the rear end at the front end of the drum in the direction of rotation, and forms a second tooth wall inclined toward the front end at the rear end, and the inclination of the first tooth wall is greater than the inclination of the second tooth wall

[0015] In order to better rotate the tongue plate, preferably, a handle for grabbing is protruded from the tongue plate toward the opposite side of the drum, and an operating hole for exposing the handle is opened on the corresponding side of the shell.

[0016] The technical solution adopted by the utility model to solve the second technical problem is as follows: the roller is detachably arranged on the shell, and a first arc groove is provided on two opposite side walls of the shell.

When the seeds or fertilizers at the feed port enter the feeding channel under the drive of the roller and fall toward the discharge port, since the tongue plate here has a certain elasticity, the feeding channel can achieve extrusion buffering under the elastic deformation of the tongue plate, so that the feeding of seeds or fertilizers can be smoother, avoiding the blockage, crushing and crushing caused by encountering some relatively large seeds in the prior art. In addition, by arranging a quickly detachable roller, the sowing and fertilizing dual-purpose box can quickly switch between two different operations of sowing and fertilizing.

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 7The preferred embodiment of the utility model is shown in FIG. 1. The sowing and fertilizing dual-purpose box in this embodiment mainly comprises a housing 1, a roller 2, a tongue plate 3 and an adjusting device 5, etc.

[0031] refer to Figures 1 to 4 As shown, in this embodiment, the drum 2 is rotatably arranged in the shell body 1, and the shell body 1 is provided with a feed port 1a and a discharge port 1b. The outer peripheral surface of the drum 2 is provided with a rolling tooth 2a. The shell body 1 is also provided with an arc-shaped tongue plate 3 for adapting to the drum 2. There is a feeding channel 4 formed by the interval between the inner arc wall 3a of the tongue plate 3 and the outer peripheral surface of the drum 2. The seeds or fertilizers at the feed port 1a enter the feeding channel 4 under the drive of the drum 2 and fall from the discharge port 1b. The feeding channel 4 can be adjusted in size under the elastic deformation of the tongue plate 3. Here, the rotation of the drum 2 is driven by a motor, and the rotation speed is controlled by a controller connected to the motor.

[0032] In this embodiment, in order to make the tongue plate 3 more elastic, Figure 2 and Figure 3 As shown, the wall thickness of the tongue plate 3 here gradually becomes thinner along the feeding direction of the feeding channel 4 so that the end of the tongue plate 3 forms elasticity. Of course, the tongue plate 3 here can also be directly made of elastic material.

[0033] In order to make the size of the feeding channel 4 adjustable in a wider range, so as to better adapt to seeds or fertilizers of different specifications, reference Figures 2 to 4 As shown, in this embodiment, the tongue plate 3 is rotatably built into the housing 1. When the tongue plate 3 rotates upward, the interval between the inner arc wall 3a of the tongue plate 3 and the drum 2 can be narrowed to reduce the material discharge channel 4. When the tongue plate 3 rotates downward, the interval between the inner arc wall 3a of the tongue plate 3 and the drum 2 can be widened to increase the material discharge channel 4. The housing 1 is also provided with an adjusting device 5 that can rotate the tongue plate 3 to a set position to be constrained and fixed. Figure 3 The figure shows the schematic diagram of the material discharge channel 4 when it is adjusted to the minimum. Figure 4 The diagram shown is a schematic diagram when the material discharge channel 4 is adjusted to the maximum.

[0034] Secondly, in order to optimize the overall structure of the adjusting device 5 so that it can lock the tongue plate 3 more conveniently, refer to Figures 2 to 4 As shown, the adjusting device 5 in this embodiment includes an adjusting pin 5a, and a plurality of adjusting holes 5b arranged up and down are also provided on the shell 1. When the tongue plate 3 is rotated to the set position, the adjusting pin 5a is inserted into the corresponding adjusting hole 5b to limit the tongue plate 3 from continuing to rotate downward to complete the adjustment of the tongue plate 3.

[0035] In this embodiment, in order to make sowing and fertilizing more accurate, reference Figure 3As shown, arrow A indicates the rotation direction of the roller when feeding, the hob 2a forms a first tooth wall 2a1 inclined toward the rear end at the front end of the roller 2 in the rotation direction, and forms a second tooth wall 2a2 inclined toward the front end at the rear end, and the slope a of the first tooth wall 2a1 is greater than the slope b of the second tooth wall 2a2. In view of the special tooth shape of the hob 2a, in conjunction with the controller connected to the motor, the motor can drive the roller 2 to rotate as needed, so that the purpose of precise delivery can be achieved.

[0036] Also, in order to better rotate the tongue plate 3, refer to Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, a handle 3b for grabbing is protruded from the tongue plate 3 toward the opposite side of the drum 2, and an operating hole 1c for exposing the handle 3b is opened on the corresponding side of the shell 1. The angle of the tongue plate 3 relative to the shell 1 can be conveniently adjusted by pulling the handle 3b.

[0037] In this embodiment, in order to quickly replace the roller 2, by replacing the roller 2 with a different pitch or tooth height, the replaced roller 2 can be better suitable for two different operations of sowing or fertilizing. Figure 6 As shown, the solution adopted here is: the roller 2 is detachably arranged on the shell 1, and a first arc groove 1d is opened on two opposite side walls of the shell 1. A notch 1e is also formed on the shell 1 on the opposite side of the operating hole 1c. The notch 1e penetrates the first arc groove 1d to form a channel for the roller 2 to be disassembled and removed. The notch 1e can also be hinged with a limit plate 6 that can be flipped. The limit plate 6 is provided with a second arc groove 6a corresponding to the first arc groove 1d. When the limit plate 6 is flipped to a closed state, the first arc groove 1d and the second arc groove 6a can enclose a mounting hole for the end of the roller 2 to be placed so that the roller 2 can be rotatably constrained on the shell 1.

[0038] In addition, in order to enable the limiting plate 6 to be quickly fixed on the housing 1, refer to Figure 6 As shown, in this embodiment, a positioning column 1f is provided on the shell 1, and a positioning hole 6b that can adapt to the positioning column 1f is provided on the limiting plate 6. When the limiting plate 6 is flipped up to a closed state, the positioning column 1f can be embedded in the positioning hole 6b to lock the limiting plate 6 on the shell 1.

[0039] In order to better control the total amount of seeds or fertilizers, refer to Figure 2 and Figure 5As shown, in this embodiment, the solution adopted is: a detachable mounting plate 7 is also provided on the housing 1, and the mounting plate 7 is formed with a partition 7a that can extend into the material discharge channel 4 and divide the material discharge channel 4 into a first material discharge channel 4a and a second material discharge channel 4b, and a third arc groove 7c adapted to the roller 2 is provided on the partition 7a, and a baffle 3c adapted to the partition 7a is also convexly provided on the inner arc wall 3a of the tongue plate 3. In order to better enable the mounting plate 7 and the housing 1 to be detachably connected, a placement groove 1g for the mounting plate 7 to be embedded is specially formed on the top of the housing 1, a buckle 7b is formed on the mounting plate 7, and a slot 1h adapted to the buckle 7b is formed on the housing 1, and the mounting plate 7 and the housing 1 are detachably mounted together through the mutual engagement of the buckle 7b and the slot 1h.

[0040] In this embodiment, reference Figure 2 As shown, in order to make the roller 2 adapt to different feeding channels 4, the roller 2 here includes a first roller 21 and a second roller 22, and the first roller 21 and the second roller 22 are mutually engaged in the axial direction to form a whole, the first roller 21 corresponds to the first feeding channel 4a, and the second roller 22 corresponds to the second feeding channel 4b. The first roller 21 and the second roller 22 are both provided with rolling teeth 2a of different sizes to adapt to seeds or fertilizers of different specifications.

[0041] In this embodiment, in order to allow seeds and fertilizers to enter the first feeding channel 4a or the second feeding channel 4b more accurately, Figure 2 and Figure 5 As shown, a cover plate 8 that can be slid open is also provided at the discharge port 1b, and the cover plate 8 includes a first cover plate 8a and a second cover plate 8b. The first cover plate 8a corresponds to the first discharge channel 4a below, and the second cover plate 8b corresponds to the second discharge channel 4b below.

[0042] It is necessary to add that in this embodiment, since a tongue plate 3 which is arc-shaped and can be adapted to the drum 2 is provided in the housing 1, a feeding channel 4 for seeds or fertilizers to fall is formed between the inner arc wall 2a of the tongue plate 2 and the outer peripheral surface of the drum 2. When the seeds or fertilizers at the feed port 1a enter the feeding channel 4 under the drive of the drum 2 and fall toward the discharge port 1b, since the tongue plate 2 here also has a certain elasticity, the feeding channel 4 can achieve extrusion buffering under the elastic deformation of the tongue plate 3, so that the feeding of seeds or fertilizers can be smoother, avoiding the blockage, crushing and crushing phenomenon caused by encountering some relatively large seeds in the prior art. When it is necessary to adjust the feeding channel 4 to a larger angle, it can also be quickly achieved by rotating the tongue plate 2. In addition, by providing a drum 2 that can be quickly disassembled, the sowing and fertilizing dual-purpose box can quickly switch between two different operations of sowing and fertilizing. In addition, since the hobbing teeth 2a on the drum 2 are also provided with a special tooth shape, together with the controller driving the motor, the motor can drive the drum 2 to rotate as needed, thereby achieving the purpose of precise delivery.
