Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural machinery technology, in particular to a seeding and soil covering device suitable for rice dry seedling raising. BACKGROUND

[0002] The rice dry seedling raising technology has become one of the core links of modern agricultural rice planting because it can significantly improve the seedling resistance and shorten the seedling raising period. The soil covering operation after seeding is a key process that determines the quality of dry seedling raising. Uniform soil covering thickness (usually controlled at 0.5-2 cm) can ensure the stability of temperature and humidity during seed germination and reduce the phenomenon of seedling deficiency and weak seedlings. However, in the current seeding and soil covering operation of rice dry seedling raising, the existing devices generally have problems such as uneven soil covering thickness, poor adaptability, and operation dependence on manual operation, which seriously restricts the large-scale application of dry seedling raising technology.

[0003] Most of the existing soil covering devices adopt a storage box structure with a fixed discharge port. The soil is covered by falling from the storage box through movement. However, in actual operation, as the soil level in the storage box changes from high to low, the pressure difference of the soil on the discharge port is significant: when the level is high, the soil particles flow continuously under the action of pressure, the discharge flow per unit time is large, and the soil covering is thick; when the level is low, the soil flow is intermittent due to insufficient pressure, the flow is reduced, and the soil covering is thin. The flow fluctuation caused by the change of the level makes the difference of the soil covering thickness of the same batch of seedling trays or single row seeding area reach 0.8-1.2 cm, directly affecting the consistency of seed germination and increasing the difficulty of later field management.

[0004] At the same time, the size of the discharge port of the existing device is mostly fixed design, which cannot be flexibly adjusted according to the different needs of different varieties of rice seeds for soil covering thickness (such as the need for thicker soil covering for indica rice and thinner soil covering for japonica rice). Different specifications of discharge components need to be replaced, which is cumbersome and inefficient. In addition, most devices lack soil reserve monitoring and early warning functions. The soil covering is often interrupted due to sudden depletion of soil in the storage box during operation, which requires manual shutdown and replenishment, not only reducing the operation efficiency, but also easily causing uneven thickness at the interface between the soil covering before and after replenishment.

[0030] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced without the specific details. In other instances, well-known methods have not been described in detail in order not to unnecessarily obscure aspects of the present application. Accordingly, it will be appreciated that the present application can be practiced with modification and alteration, and that the present application be limited by the

[0031] Second, as used in this description, the term "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the present application. The appearances of the phrase "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are the various embodiments necessarily mutually exclusive combinations of the features they describe.

[0032] Embodiment 1 : Reference Figures 1-6 Figure 8 and Figure 9 ​For the first embodiment of the application, the embodiment provides a seeding and soil covering device suitable for rice dry seedling raising, which comprises a main body assembly 1, including a storage box 11 for storing soil, the storage box 11 is fixed with a first guide plate 12 and a second guide plate 13, the first guide plate 12 and the second guide plate 13 are used to support the soil and guide the falling of the soil, the first guide plate 12 and the second guide plate 13 have a certain distance, thereby forming a discharge port, the first guide plate 12 is fixed with a support shell 14 on one side, the storage box 11 is rotatably connected with a rotating rod 15, the rotating rod 15 is fixed with a baffle 16 on the surface, the baffle 16 is located on one side of the second guide plate 13, as shown in the figure, the baffle 16 and the support shell 14 cooperate to block the discharge port, the rotating rod 15 is fixed with a swing rod 17 on the surface, the swing rod 17 is provided with a sliding groove 17-1, and a driving block 18 is slidably arranged in the sliding groove 17-1, the swing rod 17 is swung by the driving block 18, so that the rotating rod 15 is rotated, thereby making the baffle 16 swing, so that the end of the baffle 16 is away from the support shell 14, so that the soil falls from the discharge port, thereby covering the seeds with soil, the driving block 18 is fixed with a driving rod 19 on one side, the storage box 11 is fixed with a support column 110 on one side, the support column 110 is rotatably connected with an electric push rod 111 on the surface, the output end of the electric push rod 111 is rotatably connected to the surface of the driving rod 19, and the extension length of the output end of the electric push rod 111 is fixed. When the output end of the electric push rod 111 is elongated, the driving block 18 is moved by the driving rod 19, so that the driving block 18 swings the swing rod 17, if the driving block 18 moves upward along the sliding groove 17-1 from the current figure, under the condition that the extension length of the output end of the electric push rod 111 is fixed, the angle of the swing rod 17 driven by the driving block 18 will decrease, so that the opening angle of the baffle 16 decreases, that is, when the baffle 16 is completely opened, the gap distance between the baffle 16 and the support shell 14 will decrease, which is called discharge port reduction, so that the falling speed of the soil is slowed down, and under the condition that the moving speed of the storage box 11 is unchanged, the soil covering thickness of the seeds will be reduced.

[0033] However, with use, the amount of soil in the storage box 11 decreases, and under the condition that the size of the discharge port is unchanged: When the soil level in the storage box 11 is high, the pressure of the upper layer of material gradually increases, pushing the particles in the discharge port to flow more densely and continuously, and the flow naturally increases, at this time the soil covering thickness is maximum; When the soil level in the storage box 11 is low, the pressure of the upper layer of material on the particles in the discharge port is small, the particles flow discontinuously, and the flow naturally decreases, at this time the soil covering thickness is minimum.

[0034] Therefore, if the soil level in the storage box 11 is high, the size of the discharge port is reduced, and if the soil level in the storage box 11 is low, the size of the discharge port is increased, so that the flow of the discharge port is maintained stable, thereby achieving the purpose of uniform thickness of the soil covering.

[0035] Therefore, when in use, as the soil level in the storage box 11 gradually decreases, the driving block 18 is moved along the chute 17-1 from top to bottom, so that the rotating angle of the baffle 16 is increased, thereby gradually increasing the size of the discharge port, so as to reduce the influence of the non-uniform thickness of the soil covering caused by the change of the soil level in the storage box 11.

[0036] The adjusting assembly 2 is arranged on the storage box 11 and comprises a support 21 arranged in the storage box 11. The support 21 comprises a support seat 211 fixed to the inner wall of the storage box 11. The bottom of the support seat 211 is fixed with a support pipe 212. A piston 213 is slidably arranged in the support pipe 212. The connection between the piston 213 and the support pipe 212 is sealed to prevent gas leakage. A compression spring is arranged in the support pipe 212 and used to reset the piston 213 downward. The bottom of the piston 213 is fixed with a support rod 214. A rotating shaft 215 is rotatably connected in the support rod 214. Support wheels 216 are fixed to the two ends of the rotating shaft 215. Tracks arranged on the field are arranged below the support wheels 216, so that the support wheels 216 can stably move. The rotating shaft 215 can be driven by a motor, so that the rotating shaft 215 rotates at a constant speed, thereby enabling the storage box 11 to move at a stable speed and ensuring the uniform thickness of the soil covering. The technical solution of the motor driving the rotating shaft 215 to rotate is the prior art, and the working principle thereof is clear to those skilled in the art, which will not be described here.

[0037] Embodiment 2: Refer to Figures 1-3 、 Figure 7 、 Figure 8 and Figure 10 , which is a second embodiment of the present application and is based on the previous embodiment.

[0038] Specifically, the adjusting assembly 2 further comprises an adjusting part 22 arranged on one side of the storage box 11. The adjusting part 22 comprises a support block 221 fixed to one side of the storage box 11. A sliding column 222 is fixed in the support block 221. An adjusting plate 223 is slidably arranged on the surface of the sliding column 222. An adjusting groove 223-1 is formed in the adjusting plate 223. The driving rod 19 is slidably arranged in the adjusting groove 223-1. The adjusting groove 223-1 is used to limit the movement track of the driving rod 19. By moving the adjusting plate 223, the driving rod 19 can drive the driving block 18 to move, thereby changing the position of the driving block 18 in the chute 17-1, so as to change the size of the opening of the baffle 16, thereby adjusting the size of the discharge port.

[0039] Specifically, the adjusting member 22 further comprises a telescopic sleeve 224 fixed on one side of a support block 221, which can be extended when the air pressure in the telescopic sleeve 224 increases and can be shortened when the air pressure in the telescopic sleeve 224 decreases. The telescopic sleeve 224 slides on the surface of the slide column 222, and the other end of the telescopic sleeve 224 is fixed on the bottom of the adjusting plate 223.

[0040] Through the telescopic movement of the telescopic sleeve 224, the adjusting plate 223 can be driven to slide on the surface of the slide column 222, so as to change the position of the adjusting plate 223 and adjust the size of the discharge port.

[0041] Specifically, the adjusting member 22 further comprises a telescopic sleeve 224 fixed on one side of a support block 221, which can be extended when the air pressure in the telescopic sleeve 224 increases and can be shortened when the air pressure in the telescopic sleeve 224 decreases. The telescopic sleeve 224 slides on the surface of the slide column 222, and the other end of the telescopic sleeve 224 is fixed on the bottom of the adjusting plate 223.

[0042] The gas conveying pipe 225 is used to connect the support pipe 212 and the telescopic sleeve 224. When the gas in the support pipe 212 enters the telescopic sleeve 224, the telescopic sleeve 224 will be extended, and when the gas in the telescopic sleeve 224 enters the support pipe 212, the telescopic sleeve 224 will be shortened.

[0043] Embodiment 3 Refer to Figures 1-3 and Figure 7 The third embodiment of the present application is based on the first two embodiments.

[0044] Specifically, the adjusting assembly 2 further comprises a discharging member 23 arranged on the support shell 14. The discharging member 23 comprises a discharging plate 231 sliding in the support shell 14. By changing the position of the discharging plate 231, the size of the discharge port in the initial state can be changed, so as to adapt to the different soil thicknesses required by different seeds. The end of the discharging plate 231 is fixed with a positioning rod 232, and the surface of the storage box 11 is provided with a moving groove 11-1. The positioning rod 232 slides in the moving groove 11-1. By moving the positioning rod 232, the position of the discharging plate 231 can be changed, so as to change the size of the discharge port in the initial state. By positioning the positioning rod 232, the size of the discharge port in the initial state can be fixed.

[0045] Specifically, the discharging member 23 further comprises a fixed column 233 fixed on the surface of the storage box 11. The surface of the fixed column 233 is rotatably connected with a positioning plate 234. The positioning plate 234 can be stably rotated through the arrangement of the fixed column 233. The surface of the positioning plate 234 is provided with a clamping groove 234-1. The positioning rod 232 is clamped in the clamping groove 234-1, so as to position the positioning rod 232 and fix the size of the discharge port in the initial state. There are a plurality of clamping grooves 234-1. By clamping the positioning rod 232 in different clamping grooves 234-1, the size of the discharge port in the initial state can be changed, so as to adapt to the different soil thicknesses required by different seeds.

[0046] Specifically, the positioning plate 234 is fixed with an adjusting column 235 on one side, the surface of the slide column 222 is slidably provided with a displacement plate 236, the surface of the displacement plate 236 is provided with a through slot 236-1, and the adjusting column 235 slides in the through slot 236-1.

[0047] When the positioning rod 232 is clamped in different clamping grooves 234-1, the inclination angle of the positioning plate 234 is different, so that the adjusting column 235 presses the inner wall of the through slot 236-1, and the displacement plate 236 is moved to different heights.

[0048] Specifically, the adjusting plate 223 is fixed with a mounting sleeve 237 on the surface, the mounting sleeve 237 is fixed with a photoelectric sensor 238, and the mounting sleeve 237 is used for fixedly mounting the photoelectric sensor 238.

[0049] Specifically, the displacement plate 236 is fixed with a detection plate 239 on the top through bolts, when the detection plate 239 is at a fixed distance from the photoelectric sensor 238, it can be detected by the photoelectric sensor 238, at this time, it indicates that the material level of the soil in the storage box 11 reaches the lowest threshold, and because different seeds require different soil thickness, the requirement for the lowest threshold of the material level is different.

[0050] When the soil thickness required by the seed is large, at this time, the discharge port needs to reach the maximum in the initial state, that is, the positioning rod 232 is limited by the leftmost clamping groove 234-1, and in the current state, the inclination angle of the positioning plate 234 relative to the horizontal plane is the largest, that is, the displacement plate 236 moves to the maximum height, at this time, when the photoelectric sensor 238 detects the detection plate 239, the "lowest threshold" of the soil in the storage box 11 at this time is the highest.

[0051] When the soil thickness required by the seed is small, at this time, the discharge port needs to reach the minimum in the initial state, that is, the positioning rod 232 is limited by the rightmost clamping groove 234-1, at this time, the inclination angle of the positioning plate 234 relative to the horizontal plane is the smallest, that is, the displacement plate 236 moves to the bottom height, at this time, when the photoelectric sensor 238 detects the detection plate 239, the "lowest threshold" of the soil in the storage box 11 at this time is the lowest.

[0052] In this way, the "lowest threshold" of the soil in the storage box 11 matches the soil thickness required by different seeds, especially in the case of one-way reciprocating movement of the storage box 11 once, covering the soil of a single row of seeds, it is necessary to ensure that the amount of soil in the storage box 11 can meet the demand of single-row soil covering, that is, the precision requirement of the "lowest threshold" of the soil in the storage box 11 is more significant.

[0053] The storage box 11 is fixed with a protective shell 2310 on one side, and the protective shell 2310 is used for protecting the mechanism on one side of the storage box 11.

[0054] Specifically, the surface of the storage box 11 is fixed with an audible and visual alarm 2311. When the photoelectric sensor 238 detects the detection plate 239, the audible and visual alarm 2311 starts to alarm, prompting to add material to the storage box 11, avoiding the situation that the soil in the storage box 11 is suddenly used up during the covering process.

[0055] In use, initial preparation: according to the covering thickness requirement of the rice seeds to be covered, adjust the discharging part 23 to set the initial discharging port size. Push the positioning rod 232 to slide along the moving groove 11-1 of the storage box 11, drive the discharging plate 231 in the support shell 14 to move, adjust to the target initial discharging port size, then rotate the positioning plate 234, and fix the positioning rod 232 in the corresponding clamping groove 234-1 of the positioning plate 234. At this time, the inclination angle of the positioning plate 234 changes. By adjusting the column 235 to press the through groove 236-1 of the displacement plate 236, the displacement plate 236 drives the detection plate 239 to move to the height suitable for the covering thickness, and the photoelectric sensor 238 sets the soil material level minimum threshold value.

[0056] Start operation: load soil into the storage box 11. The soil is guided to converge to the discharging port by the first guide plate 12 and the second guide plate 13. Start the motor to drive the rotation shaft 215 of the supporting part 21 in the adjusting assembly 2, drive the supporting wheel 216 to roll along the track at a constant speed, and make the storage box 11 move at a stable speed. At the same time, start the electric push rod 111, whose output end is extended through the drive rod 19 to drive the drive block 18 to slide in the sliding groove 17-1 of the swing rod 17, drive the swing rod 17 to rotate, and then make the baffle 16 away from the support shell 14, open the discharging port to form the discharging port, and the soil falls to cover the seeds.

[0057] Dynamic adjustment: as the operation proceeds, the soil material level in the storage box 11 decreases. The piston 213 in the supporting pipe 212 moves downward relative to the supporting pipe 212 as the soil pressure decreases. The gas in the telescopic sleeve 224 enters the supporting pipe 212 through the gas conveying pipe 225. The telescopic sleeve 224 shortens, pulls the adjusting plate 223 to slide downward along the sliding column 222, drives the drive rod 19 through the adjusting groove 223-1, and makes the drive block 18 move downward along the sliding groove 17-1, increases the swing angle of the swing rod 17, and makes the baffle 16 further open. The discharging port is expanded accordingly, offsetting the decrease in flow caused by the decrease in material level, and maintaining the uniformity of the covering thickness.

[0058] Supplement warning: when the soil material level in the storage box 11 decreases to the set minimum threshold value, the detection plate 239 moves to the detectable position of the photoelectric sensor 238. The photoelectric sensor 238 triggers the audible and visual alarm 2311 to alarm, prompting the staff to supplement the material in the storage box 11, avoiding the interruption of covering.

[0059] Stop working: after finishing covering, the motor and the electric push rod 111 are turned off, the output end of the electric push rod 111 is retracted to drive the baffle 16 to reset, the baffle 16 cooperates with the supporting shell 14 to block the discharging port, the soil falling is stopped, and the storage box 11 stops moving, and the working is finished.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
