Description

Technical Field

[0001] The invention relates to the field of rice seedling cultivation, and in particular to a rice seedling cultivation substrate and a preparation device thereof. Background Art

[0002] As is known, the seedling medium refers to the material used to provide the physical and chemical environment required for plant growth during the seedling raising process. It is usually mixed with multiple components to ensure good drainage, ventilation and nutrient supply. During the production process, multiple raw materials need to be piled up for fermentation. During the fermentation process, in order to ensure uniform fermentation, the raw materials need to be turned over.

[0003] For example, the Chinese patent document with authorization announcement number CN205855425U, announcement date 2017-01-04, and name "A biogas residue compost turning machine" includes a biogas residue trough, parallel side walls are arranged on the left and right sides of the biogas residue trough, guide rails are arranged above the side walls, and a compost turning machine is movably arranged on the guide rails. The compost turning machine includes a frame, an operation room and a power room are arranged on the upper part of the frame, a driving mechanism is arranged in the power room, a walking mechanism and a turning and throwing mechanism are arranged on the lower part of the frame, and the turning and throwing mechanism includes a group of front supports and rear supports symmetrically arranged at the bottom of the frame, the front supports and the rear supports are hinged by connecting parts, a rotating shaft is arranged between the connecting parts, and rake teeth are circumferentially staggered on the rotating shaft.

This patent provides a biogas sludge compost turning machine with simple structure, convenient operation, low energy consumption, uniform mixing, high efficiency, wide adaptability and long service life.

[0004] The disadvantages of the above-mentioned prior art are that when the raw materials are turned over, the stacked raw materials are turned over row by row by the turning wheel that moves and rotates. However, during the turning process, the raw materials will splash to both sides, causing the turned substrate to fall on the surface of the unturned substrate. When the substrate at this position is turned over, the turned raw materials will be turned over for the second time, so that they are pressed on the bottom layer again, thereby reducing the turning effect.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] In the description of the present invention, it should be understood that Figure 4 the position of the cutting edge 12 relative to the first transmission rod 14 is considered left, and vice versa for right. The orientation or positional relationship indicated by terms such as "center", "length", "width", "degree", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention 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 thus should not be construed as a limitation to the present invention.

[0030] Referring to Figure 1-6 , a preparation device for a rice seedling raising substrate provided by an embodiment of the present invention includes a frame 1 and a turning wheel 2 rotatably arranged on the frame 1 for turning the substrate over, and further includes a traveling mechanism for adjusting the position of the turning wheel 2. A substrate isolation plate 3 for blocking both sides of the substrate during the substrate turning process is arranged on the frame 1.

[0031] Specifically, the frame 1 is in a U-shaped configuration. Both ends of the turning wheel 2 are rotatably arranged on the frame 1 through bearings. The turning wheel 2 is in a cylindrical shape, and a plurality of turning rods are arranged on its outer peripheral surface. The traveling mechanism can be a vehicle body or a three-axis moving mechanism (which can drive the turning wheel 2 to move in the horizontal plane and the vertical plane). During the turning process, the turning wheel 2 is driven to rotate by an existing driving structure such as a reduction motor. At the same time, the position of the turning wheel 2 is adjusted through the traveling mechanism so that the rotating turning wheel 2 can turn the substrate over to improve the fermentation efficiency of the substrate. This is the prior art and will not be elaborated. However, the above-mentioned turning method will cause the turned raw materials to be turned over again, so that they are pressed at the bottom layer again. One of the core innovation points of the embodiment of the present invention is that a substrate isolation plate 3 is arranged on the frame 1. There are two substrate isolation plates 3, and the two substrate isolation plates 3 are respectively located between both ends of the turning wheel 2 and the inner walls on both sides of the frame 1. It has a rectangular structure, that is, both sides behind the movement stroke of the turning wheel 2 are blocked by the substrate isolation plates 3. The function of such a setting is to control the rotation of the turning wheel 2 and adjust the position of the turning wheel 2 through the traveling mechanism to turn the substrate over. During the turning process, the substrate splashing to both sides will be blocked by the single-row isolation mechanism, so as to尽量 avoid the turned substrate from falling on the surface of the unturned substrate, thereby尽量 avoiding its secondary turning and improving the turning effect.

[0032] Since the substrate after turning over will become more fluffy, the space it occupies will increase. Since the two sides of the substrate after turning over are blocked by the substrate isolation plate 3, that is, the horizontal area of ​​the substrate after turning over will not increase, the vertical height of the substrate will increase. At this time, a fault appears between the substrate after turning over and the substrate not turned over, so the substrate after turning over will collapse toward the substrate not turned over. Furthermore, protrusions 4 are respectively provided on the opposite surfaces of the two substrate isolation plates 3. Specifically, the surface of the protrusion 4 is arc-shaped, which is gradually thickened along the direction of the movement of the turning wheel 2 and is close to the middle position of the substrate isolation plate 3. The effect of such a setting is that the substrate after turning over by the turning wheel 2 will be located between the two substrate isolation plates 3, and the substrate located on the surface will abut against the protrusion 4. Since the protrusion 4 is gradually thickened along the direction of the movement of the turning wheel 2, it will produce a squeezing effect on the substrate on the surface, making it difficult for the substrate on the surface to collapse.

[0033] Furthermore, a baffle 5 is provided between the two matrix isolation plates 3. Specifically, the two ends of the baffle 5 are rotatably connected to the inner walls of the two sides of the matrix isolation plate 3, and the baffle 5 is close to the top of the matrix isolation plate 3 and is located behind the movement stroke of the pile turning wheel 2. The effect of such a setting is that the higher matrix rolled by the pile turning wheel 2 will hit the baffle 5, which will drive the baffle 5 to swing, so that the matrix attached to the baffle 5 falls quickly.

[0034] When the turning wheel 2 is controlled to descend, in order to avoid damage to the turning rod caused by contact between the turning rod and the ground, a gap of 3-5 cm will be left between the turning rod and the ground when the turning wheel 2 is controlled to descend. The substrate in this part cannot be turned over, and under the effect of the segregation effect, the substrate is unevenly distributed, thereby reducing the fermentation effect of the substrate. Further, a shoveling mechanism for shoveling up the bottom substrate is provided on the substrate isolation plate 3. Specifically, the shoveling mechanism can be a structure such as a scraper, which is used to shovel up the bottom substrate during the process of turning over the substrate, so that the bottom substrate moves up to the height of the turning wheel 2, and is turned over by the turning wheel 2 to improve the fermentation effect of the substrate.

[0035] As an alternative solution for the scraper to scoop up the bottom substrate, the bottom scooping mechanism includes a bottom plate 6 arranged between the two substrate isolation plates 3, and a first scooping portion 7 is arranged on the bottom plate 6. Specifically, an approximately U-shaped structure is formed between the bottom plate 6 and the two matrix isolation plates 3, and the turning wheel 2 is arranged in the internal space between the two, and the gap between the turning wheel 2 and the upper surface of the bottom plate 6 is certain, which can be set to be less than 1 cm. The first scooping portion 7 is an inclined surface arranged on the end of the bottom plate 6, and is located in front of the movement stroke of the turning wheel 2. The purpose of such a setting is that when the vertical height of the turning wheel 2 is adjusted, the matrix isolation plate 3 and the bottom plate 6 are controlled to descend synchronously. When the lower surface of the bottom plate 6 contacts the ground, the descending is stopped. At this time, when the turning wheel 2 moves horizontally, the first scooping portion 7 on the bottom plate 6 will scoop up the matrix of the bottom layer, and move to the upper surface of the bottom plate 6 along the inclined surface of the first scooping portion 7 during the movement. At this time, since the gap between the turning rod and the bottom plate 6 is always certain, the turning rod will turn over the bottom layer of the matrix to the greatest extent without interfering with the ground, so that the turning rod can be damaged as much as possible during the turning.

[0036] Further, a second scooping portion 8 is slidably provided on the first scooping portion 7, and a first elastic member 9 is provided between the first scooping portion 7 and the second scooping portion 8. Specifically, a horizontal groove is provided on the first scooping portion 7, and the second scooping portion 8 is slidably connected to the horizontal groove. The first elastic member 9 is preferably a spring, one end of which is fixedly connected to the side wall of the horizontal groove, and the other end is fixedly connected to the second scooping portion 8, and the first scooping portion 7 is located behind the movement stroke of the second scooping portion 8. The effect of such a setting is that when the bottom plate 6 moves horizontally to scoop up the bottom substrate and encounters agglomerated substrates or stones (hereinafter referred to as impurities for the convenience of description), the second scooping portion 8 will preferentially contact them, and make the second scooping portion 8 slide toward the inside of the horizontal groove, and accumulate force on the first elastic member 9, so that in the subsequent movement of the second scooping portion 8, the second scooping portion 8 will scoop up the impurities to achieve the effect of buffering the scooping of impurities, thereby minimizing the damage of the second scooping portion 8.

[0037] During the movement of the matrix isolation plate 3, if the ground is sunken, the matrix at the sunken position cannot be scooped up, resulting in a dead angle for turning over. If the ground is slightly convex, the second scooping part 8 will interfere with the convexity, so that the bottom plate 6 cannot continue to move or the bottom plate 6 can only be moved after being lifted by the walking mechanism. As another embodiment of the present invention, a slide groove 10 is provided on the first scooping part 7, and a sliding connection part 11 is provided on the second scooping part 8, and the sliding connection part 11 is slidably connected to the slide groove 10. Specifically, in the present embodiment, the first elastic member 9 is arranged between the slide groove 10 and the sliding connection portion 11, the slide groove 10 is opened along the inclined surface of the first scooping portion 7, the sliding connection portion 11 is slidably connected to the slide groove 10, and a limiting structure for preventing the two from being separated from each other is arranged between the two. When the matrix isolation plate 3 is not in contact with the ground, the lower end of the second scooping portion 8 is lower than the lower surface of the matrix isolation plate 3, and the lower surface of the matrix isolation plate 3 is lower than the lower surface of the bottom plate 6, that is, when the matrix isolation plate 3 is in contact with the ground, there is a gap between the bottom plate 6 and the ground for a slight protrusion to pass through. The second scooping part 8 is in the same position as the first scooping part 8, and the second scooping part 8 is in the same position as the first scooping part 8. The second scooping part 8 is in the same position as the first scooping part 8, and the second scooping part 8 is in the same position as the first scooping part 8. The second scooping part 8 is in the same position as the first scooping part 8, and the second scooping part 8 is in the same position as the first scooping part 8. First, when encountering impurities, the first elastic member 9 further contracts to achieve the effect of buffering scooping. Second, when encountering a concave position on the ground, the elastic force of the first elastic member 9 is released, so that the second scooping portion 8 slides obliquely downward along the inclined surface of the first scooping portion 7, so that the end of the second scooping portion 8 is inserted into the concave position and scoops up the substrate at the concave position. When the second scooping portion 8 subsequently moves up along the concave position, it will accumulate force on the first elastic member 9 again to achieve automatic reset of the second scooping portion 8. Third, when encountering a slight bulge on the ground, it will make the second scooping portion 8 The scooping portion 8 abuts against the slightly raised position, so that the second scooping portion 8 slides obliquely upward along the inclined surface of the first scooping portion 7. When the lower end of the second scooping portion 8 is higher than the top of the slightly raised portion, the second scooping portion 8 will pass over the slightly raised portion and further accumulate force on the first elastic member 9 to avoid it (in the subsequent movement, the slightly raised portion will pass through the gap between the bottom plate 6 and the ground to avoid it). When the second scooping portion 8 moves away from the slightly raised portion, a part of the elastic force of the first elastic member 9 is released to drive the second scooping portion 8 to automatically reset.

[0038] Furthermore, a cutting blade 12 is slidably provided on the matrix isolation plate 3, and the cutting blade 12 has a first state for cutting the matrix and a second state for storage; and a power assembly for driving the cutting blade 12 to switch between the first state and the second state is also included. Specifically, a movable groove 13 is provided at one end of the matrix isolation plate 3 close to the turning wheel 2, and the cutting blade 12 is slidably provided in the movable groove 13, and a limiting structure for preventing the two from being separated is also provided between the two, and the power assembly can be an existing reciprocating drive assembly such as an electric push rod. The effect of such a setting is that when it is necessary to turn the matrix over, the cutting blade 12 is controlled by the power assembly to be in the first state, and at this time, when the matrix isolation plate 3 moves horizontally, the cutting blade 12 can cut the matrix to reduce the resistance of the matrix isolation plate 3 when it moves horizontally, and when the matrix is ​​turned over, the cutting blade 12 is controlled by the power assembly to switch from the first state to the second state, and at this time, the cutting blade 12 is stored in the movable groove 13 to hide its sharp end, so as to avoid the cutting blade 12 from accidentally injuring people as much as possible, thereby improving the safety of the device.

[0039] As an alternative solution for the above-mentioned electric push rod to drive the cutting blade 12 to switch between the first state and the second state, preferably, the power assembly includes a first transmission rod 14 and a second transmission rod 15, and an installation groove 16 is opened inside the base plate 6. The first transmission rod 14 is slidably set in the installation groove 16, and the second transmission rod 15 is rotatably set in the installation groove 16. The two ends of the second transmission rod 15 are respectively abutted against the first transmission rod 14 and the cutting blade 12, and a second elastic member 17 is arranged between the cutting blade 12 and the matrix isolation plate 3. Specifically, a fixed shaft is arranged inside the mounting groove 16, the second transmission rod 15 is rotatably connected to the fixed shaft, and the fixed shaft is eccentrically arranged, that is, the distance between the fixed shaft and the first transmission rod 14 is smaller than the distance between the fixed shaft and the cutting blade 12, the mounting groove 16 is connected to the slide groove 10, the first transmission rod 14 is horizontally slidably arranged in the mounting groove 16, and one end of the first transmission rod 14 abuts against the second transmission rod 15, and the other end extends into the slide groove 10, and an arc surface is arranged on one end located inside the slide groove 10, the arc surface of the first transmission rod 14 is located on the movement stroke of the sliding portion 11, and the second elastic member 14 is arranged on the sliding groove 10. The elastic member 17 is also preferably a spring, one end of which is fixedly connected to the cutting blade 12, and the other end is fixedly connected to the side wall of the movable groove 13. The effect of such a setting is that when the substrate is not turned over, that is, when the substrate isolation plate 3 is away from the ground, the elastic force of the first elastic member 9 makes the sliding portion 11 and the arc end of the first transmission rod 14 away from each other, and under the action of the elastic force of the second elastic member 17, the cutting blade 12 is in the second state, and the two ends of the second transmission rod 15 are always in contact with the cutting blade 12 and the end of the first transmission rod 14, so as to avoid the first transmission rod 14 and the second transmission rod 15 from being in contact with each other as much as possible. The transmission rod 15 is shaken at will. When the substrate is turned over, the substrate isolation plate 3 is controlled to descend. In this process, the second scooping portion 8 will abut against the ground. When the second scooping portion 8 slides upward along the inclined surface of the first scooping portion 7, the sliding portion 11 will slide with the arc-shaped end of the first transmission rod 14, so that the other end of the first transmission rod 14 squeezes the second transmission rod 15, so that the second transmission rod 15 rotates around the fixed axis. Since the other end of the second transmission rod 15 abuts against the cutting blade 12, and the fixed axis is eccentrically arranged, under the action of the lever principle, the second transmission rod 15 can rotate around the fixed axis. A transmission rod 14 moves a short distance to push the cutting blade 12 out of the movable groove 13, so that the cutting blade 12 is passively switched from the second state to the first state, and the second elastic member 17 is charged to cut the substrate. When the substrate is turned over, the substrate isolation plate 3 is lifted. During the lifting process, the elastic force of the first elastic member 9 is released, so that the second scooping portion 8 is automatically reset, and the sliding portion 11 is separated from the arc end of the first transmission rod 14. At the same time, the elastic force of the second elastic member 17 is released to drive the cutting blade 12 to passively switch from the first state to the second state.

[0040] When the second scooping portion 8 encounters a slight depression, the second scooping portion 8 will slide obliquely downward, thereby causing the sliding portion 11 to slide obliquely downward, causing the cutting blade 12 to shrink a portion toward the inside of the movable groove 13, making it impossible for the cutting blade 12 to cut stably. As another embodiment of the present invention, an abutment portion 18 is provided on the first transmission rod 14, and a locking rod 19 is slidingly provided inside the installation groove 16. A third elastic member 20 is provided between the locking rod 19 and the inner wall of the installation groove 16. The locking rod 19 is located on the movement stroke of the abutment portion 18. A locking hole 21 is provided on the side wall of the cutting blade 12, and the locking rod 19 is located on the movement stroke of the locking hole 21. Specifically, as Figure 4As shown, the locking hole 21 is located on the side wall of the cutting blade 12, and an opening is provided on the locking hole 21, the abutment portion 18 is provided on the side of the first transmission rod 14, and the surface is arc-shaped, the locking rod 19 is an elastic telescopic rod (that is, it includes a left section and a right section that are slidably connected to each other, and a spring and other structures are provided between the two sections, so that the locking rod 19 can be axially telescopic), and its end away from the cutting blade 12 is also arc-shaped, and an extension portion 22 is provided on the locking rod 19. The third elastic member 20 is also preferably a spring, one end of which is fixedly connected to the extension portion 22, and the other end is fixedly connected to the inner wall of the mounting groove 16. A torsion spring (not shown in the figure) is provided between the second transmission rod 15 and the fixed shaft, and the elastic force of the torsion spring makes the second transmission rod 15 have There is a tendency to rotate clockwise. The purpose of such a setting is that when the cutting blade 12 switches from the second state to the first state, the sliding portion 11 will abut against the first transmission rod 14, so that the first transmission rod 14 slides in the direction of the second transmission rod 15 and accumulates force on the torsion spring, and the abutting portion 18 will abut against the arc-shaped end of the locking rod 19 to provide a force for the locking rod 19 to slide to the left. At this time, the end of the left section of the locking rod 19 abuts against the side wall of the cutting blade 12, so that the left section of the locking rod 19 cannot move, and the right section slides normally to the left. In this process, the third elastic member 20 will be stretched, and the locking rod 19 will be contracted and shortened as a whole, and force will be accumulated on the locking rod 19. In the subsequent process of the second transmission rod 15 pushing the cutting blade 12 to switch from the second state to the first state, the locking hole 21 will be driven to move synchronously. When the locking hole 21 moves to a position coaxial with the locking rod 19 (at this time, the cutting blade 12 is in the first state), the abutment effect of the side wall of the cutting blade 12 on the left section disappears. At this time, the elastic force of the locking rod 19 is released, so that the left section is inserted into the locking hole 21, thereby having a locking effect on the cutting blade 12. When encountering a slight depression, the movement stroke of the sliding part 11 is small, and the abutment effect between the abutment part 18 and the locking rod 19 cannot disappear. At this time, the left section of the locking rod 19 is always inserted into the locking hole 21 to always lock the cutting blade 12, so that it can To improve the stability of the cutting blade 12 in the first state, when the substrate is turned over, the control frame 1 is moved upward, and the elastic force of the first elastic member 9 is released to drive the second scooping portion 8 to move obliquely downward, and make the sliding portion 11 and the first transmission rod 14 move away. At this time, the elastic force of the torsion spring is released to push the first transmission rod 14 to slide in the opposite direction. When the first transmission rod 14 drives the abutment portion 18 and the locking rod 19 away, the elastic force of the third elastic member 20 is released, thereby driving the locking rod 19 to move rightward, so as to pull the left section of the locking rod 19 out of the locking hole 21, so as to realize the passive unlocking of the cutting blade 12. At this time, the cutting blade 12 is reset from the first state to the second state under the action of the elastic force of the second elastic member 17.

[0041] It should be noted that when the second scooping portion 8 encounters a severe depression, the second scooping portion 8 will slide obliquely downward to the end of the stroke. At this time, the cutting blade 12 will also be passively unlocked, so that the cutting blade 12 switches from the first state to the second state. When the second scooping portion 8 is disengaged from the severe depression, the second scooping portion 8 will slide in the opposite direction to switch the cutting blade 12 from the second state to the first state again and lock it. When the second scooping portion 8 encounters a protrusion, the sliding portion 11 will further move obliquely upward. During this process, the width of the sliding portion 11 will cause it to always abut against the arc-shaped end of the first transmission rod 14 in the subsequent stroke, that is, during this process, the cutting blade 12 is always in the first position.
