[0001] The invention relates to the field of vegetable seedling cultivation, and in particular to a vegetable seedling cultivation substrate based on traditional Chinese medicine residues and a preparation device thereof. Background Art

[0002] As is known to all, vegetable seedling substrate refers to the growth medium used in the vegetable seedling stage, which provides the nutrients, water, air and support required by the plant roots in the early stage of vegetable seedling cultivation to improve the survival rate of vegetable seedlings.

The utility model can realize accurate control of the weight of the conveyed material, and is convenient for obtaining a bagged organic matrix of a specified weight. The feeding device loads the material and the weighing and unloading device unloads the material at the same time. On the one hand, it can avoid material hoarding and blockage, and on the other hand, it can realize continuous and large-scale packaging production with good weighing accuracy.

[0004] The shortcomings of the above-mentioned prior art are that, when the substrate is bagged, the packaging bag is sleeved on the discharge port of the hopper and then fixed by a pneumatic clamping assembly. Since the conveyor belt at the bottom of the packaging bag is always in operation, the packaging bag cannot be placed on the conveyor belt. At this time, under the action of the pneumatic clamping assembly, the packaging bag is suspended. Obviously, the suspended packaging bag lacks bottom support, so that in the subsequent bagging process, the gravity of the substrate will produce a downward pulling effect on the packaging bag, which can easily cause damage to the packaging bag.

[0029] 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.

[0030] In the description of the present invention, it is necessary to understand that Figure 2 The position of the middle push plate 13 relative to the supporting plate 3 is up, and vice versa. The terms "center", "longitudinal", "lateral", "length", "width", "degree", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0031] Reference Figure 1-6 , an embodiment of the present invention provides a device for preparing a vegetable seedling matrix based on traditional Chinese medicine residue, comprising a hopper (not shown in the figure) for storing the matrix and a conveyor belt 1 arranged below the hopper for transporting the packaging bag to the next workstation, an auxiliary mechanism is arranged between the hopper and the conveyor belt 1; the auxiliary mechanism has a first state for carrying the packaging bag and a second state for transporting the packaging bag to the conveyor belt 1.

[0032] Specifically, the hopper is funnel-shaped, with a discharge port at its bottom end, the conveyor belt 1 is located below the discharge port, and a pneumatic clamping assembly is provided at the discharge port of the hopper. When packaging the substrate, a packaging bag (based on the convenience of description, in this application, both the empty bag and the bag filled with the substrate are referred to as packaging bags) is sleeved on the outside of the discharge port. At this time, the packaging bag is located on the outside of the discharge port and on the inside of the pneumatic clamping assembly. The position of the packaging bag is then fixed by the extrusion force provided by the pneumatic clamping assembly. In order to prevent the bottom end of the packaging bag from contacting the conveyor belt 1 (because the conveyor belt 1 is always in operation, when the packaging bag contacts the running conveyor belt 1, sliding friction will be generated between the two), the packaging bag is suspended in the air at this time, and then the discharge port is opened to allow the substrate inside the hopper to fall into the packaging bag. When the substrate is bagged, the discharge port is closed, and the pneumatic clamping assembly is released. At this time, the packaging The bag falls on the conveyor belt 1 under the action of its own gravity and is transported to the next workstation. This is the prior art and will not be elaborated. One of the core innovations of the embodiment of the present invention is that an auxiliary mechanism is arranged between the discharge port of the hopper and the conveyor belt 1. The auxiliary mechanism can be a support plate arranged on the conveyor belt 1, which is located between the discharge port and the conveyor belt 1. The effect of such arrangement is that when the packaging bag is put on the discharge port of the hopper, the bottom of the packaging bag overlaps the support plate. This is the first state of the auxiliary mechanism. In the process of the matrix falling from the discharge port to the inside of the packaging bag, the support plate can play a supporting effect on the bottom of the packaging bag, so as to avoid the packaging bag from being torn as much as possible. When the matrix is ​​bagged, the auxiliary mechanism is controlled to switch from the first state to the second state. At this time, the support plate is controlled to be away from the packaging bag. At this time, the packaging bag can fall from the support plate to the conveyor belt 1 and enter the next workstation (sealing the packaging bag).

[0033] Preferably, the auxiliary mechanism includes a base 2 and a support plate 3 slidably disposed on the base 2; and also includes a first power assembly for driving the support plate 3 to slide. Specifically, there are two bases 2, and the two bases 2 are symmetrically arranged on both sides of the conveyor belt 1. There are also two support plates 3, and the two support plates 3 are slidably disposed above the base 2, respectively. The first power assembly can be an existing reciprocating drive assembly such as an electric push rod. The effect of such an arrangement is that when receiving the matrix, the two support plates 3 fit each other, and the packaging bag is placed at the junction of the two support plates 3 to receive the matrix. When the matrix is ​​received, the two support plates 3 are controlled to move toward each other so that a gap is generated between them. When the size of the gap is larger than the size of the packaging bag, the packaging bag will fall onto the conveyor belt 1 through the gap.

[0034] It should be noted that, since the packaging bag is sleeved on the discharge port of the hopper, there is a certain overlap between the bag mouth and the discharge port. After the substrate is received, a downward movement is required to separate the bag mouth and the discharge port. This means that there must be a gap between the supporting plate 3 and the conveyor belt 1 for the packaging bag to fall. However, due to the existence of the gap, after the two supporting plates 3 are separated and the pneumatic clamping assembly is released, the packaging bag will instantly fall onto the conveyor belt 1. The impact force generated during this period can easily cause the packaging bag to explode. To solve the above problem, preferably, a guide groove 4 is provided on the base 2, and a guide rod 5 is fixed to the supporting plate 3, and the guide rod 5 is slidably connected to the guide groove 4. Specifically, the guide groove 4 is opened on the two side walls of the base 2, which includes a horizontal section 401 and an inclined section 402. The inclined section 402 is arranged obliquely upward in the direction away from the conveyor belt 1. The guide rod 5 includes a connecting section and a sliding section. The connecting section is L-shaped, and the sliding section is cylindrical. The sliding section is slidably connected to the guide groove 4. For a single guide groove 4, there are two guide rods 5, and the length of the horizontal section 401 is greater than the distance between the two guide rods 5. The effect of such a setting is that when the auxiliary mechanism is in the first state, the two bearing plates 3 are in contact with each other. At this time, the two sliding sections are both located in the horizontal section 401. When the auxiliary mechanism switches from the first state to the second state, the two bearing plates 3 will be moved away from each other. It includes the following two strokes. First, it will preferentially make the guide rod 5 slide a distance along the horizontal section 401. At this time, a gap will appear between the two bearing plates 3, but the size of the gap is smaller than the size of the packaging bag. At this time, the packaging bag cannot fall from the gap. Second, the two bearing plates 3 are controlled to continue to move, thereby driving the sliding section to move synchronously. When one of the sliding sections enters the inclined section, the two bearing plates 3 will move away from each other. When the inclined section 402 continues to slide, the end of the supporting plate 3 corresponding to the sliding section will be tilted upward. At this time, the supporting plate 3 is changed from a horizontal state to an inclined state. The advantage of such a setting is that when the supporting plate 3 moves horizontally and tilts at the same time, on the one hand, the inclined supporting plate 3 can speed up the opening speed of the gap between the two supporting plates 3. On the other hand, during the tilting process of the supporting plate 3, the ends of the two supporting plates 3 close to each other will move downward, and the packaging bag will also slowly move downward under the action of its own gravity. In this way, the vertical distance between the supporting plate 3 and the conveyor belt 1 can be reduced. When the guide rod 5 moves to the end of the inclined section 402, the distance between the end of the supporting plate 3 and the conveyor belt 1 reaches the minimum value. At this time, the gap between the two supporting plates 3 can just make the packaging bag fall. In this state, the impact force generated when the packaging bag falls reaches the minimum value, thereby avoiding the explosion of the packaging bag as much as possible. That is, the supporting plate 3 has two advantages in the process. First, it plays a supporting role for the packaging bag. Second, it can reduce the impact force of the packaging bag during the descent process to protect the packaging bag.

[0035] It should be noted that, since the supporting plate 3 is tilted while moving horizontally, it is necessary to adapt the connection relationship between the first power assembly and the supporting plate 3. Preferably, the first power assembly includes a driving motor 6 arranged on the base 2 and a threaded rod 7 connected to the output end of the driving motor 6. The base 2 is provided with a slider 8 threadedly connected to the threaded rod 7. The slider 8 and the supporting plate 3 are both provided with a rotating seat 9. A connecting rod 10 is provided between the two rotating seats 9. Specifically, a mounting groove 11 is provided on the upper surface of the base 2, and the slider 8 is slidably provided in the mounting groove 11. A limiting structure for preventing the two from being separated is provided between the two. A threaded hole is provided inside the slider 8. The driving motor 6 is fixed to the side wall of the base 2. The threaded rod 7 penetrates the side wall of the base 2 and is threadedly connected to the threaded hole inside the slider 8. A rotating seat 9 is provided on the upper surface of the slider 8. A rotating seat 9 is also provided on the lower surface of the supporting plate 3. The two ends of the connecting rod 10 are respectively rotatably connected to the two rotating seats 9. The purpose of such a setting is that the two supporting plates 3 need to be controlled to move away from each other (or When the bearing plate 3 is close to the horizontal section 402, the driving motor 6 is started, and the driving motor 6 drives the threaded rod 7 at its output end to rotate, thereby driving the slider 8 to slide horizontally inside the mounting groove 11. While the slider 8 slides horizontally, the supporting plate 3 is driven to move horizontally through the connecting rod 10. When the sliding section enters the inclined section 402 (or enters from the inclined section 402 to the horizontal section 401) to drive the bearing plate 3 to tilt, the vertical distance between the bearing plate 3 and the slider 8 will increase (or decrease), so that the connecting rod 10 tilts as the bearing plate 3 tilts, thereby adapting the connection relationship between the bearing plate 3 and the slider 8.

[0036] Furthermore, a baffle 12 is provided on the conveyor belt 1. Specifically, the baffle 12 is a plate-shaped structure arranged along the length of the conveyor belt 1, which is arranged above the conveyor belt 1 and is used to block the packaging bags from both sides to prevent the packaging bags from falling from the conveyor belt 1.

[0037] It should be noted that the subsequent process of bagging is sealing, in which the opening of the packaging bag is sealed by an automatic sealing machine, which is located in the middle part of the conveyor belt 1. Since the sewing range of the automatic sealing machine is limited, if the packaging bag on the conveyor belt 1 is tilted, the packaging bag will not be able to pass through the sewing area of ​​the automatic sealing machine, resulting in leakage. In order to solve the above problem, as another embodiment of the present invention, the base 2 is provided with a directional pushing mechanism for tilting the packaging bag toward the baffle 12. Specifically, in the present embodiment, only a single baffle 12 is required, and the top of the baffle 12 is lower than the top of the packaging bag, that is, the baffle 12 will not block the area to be sewn of the packaging bag. The directional pushing mechanism can also be an existing pushing structure such as an electric push rod, and is arranged on the opposite side of the baffle 12, and the sewing area of ​​the automatic sealing machine is arranged at a position close to the baffle 12. The effect of such a setting is that after the matrix is ​​bagged, it will fall on the conveyor belt 1 under the action of the auxiliary mechanism. At this time, the directional pushing mechanism is started, which can provide a driving force for the packaging bag to tip toward the baffle 12, so that the packaging bag can only be tilted toward the direction of the baffle 12 (the tilt angle is 5°-10°), so that the packaging bag leans on the baffle 12. The advantages of such a setting are, first, the number of baffles 12 can be reduced, second, because the packaging bag leans on the baffle 12, the stability of the packaging bag during transportation can be improved, and third, the directional pushing of the packaging bag can be achieved to facilitate subsequent sealing.

[0038] Preferably, the directional pushing mechanism includes a push plate 13, a rotating shaft 14 is provided on the push plate 13, a bracket 15 is provided on the base 2, and the rotating shaft 14 is rotatably connected to the bracket 15; and also includes a second power assembly for driving the push plate 13 to rotate. Specifically, the bracket 15 is approximately C-shaped, one end of which is fixed to the side wall of the base 2, and the other end is rotatably connected to the rotating shaft 14 on the push plate 13. For a single base 2, two brackets 15 are provided, and the two brackets 15 are symmetrically arranged about the base 2. There is an escape space between the push plate 13 and the upper surface of the supporting plate 3 for the supporting plate 3 to rotate. The second power assembly can be an existing structure for providing rotational force such as a motor. The purpose of such a setting is that when the matrix is ​​bagged, the second power assembly is started, and the second power assembly drives the rotating shaft 14 to rotate, thereby driving the push plate 13 to actively rotate in the direction of the packaging bag to provide the force required for the packaging bag to tilt. After the pushing is completed, the push plate 13 is controlled to rotate in the opposite direction by the second power assembly to achieve the reset of the push plate 13.

[0039] As an alternative to the above-mentioned motor driving the push plate 13 to rotate, the second power assembly includes a transmission rod 16 fixedly connected to the rotating shaft 14, and an abutment rod 17 is provided on the guide rod 5, and the transmission rod 16 is located on the movement stroke of the abutment rod 17; a torsion spring (not shown in the figure) is provided between the rotating shaft 14 and the bracket 15. Specifically, the transmission rod 16 is L-shaped, and includes a horizontal edge 1601 and a vertical edge 1602. The bottom end of the vertical edge 1602 is provided with a wedge-shaped surface, and the wedge-shaped surface of the vertical edge 1602 is located on the movement stroke of the abutment rod 17. The bracket 15 is provided with a groove 18, and a part of the rotating shaft 14 is exposed in the groove 18. The end of the horizontal edge 1601 of the transmission rod 16 is fixedly connected to the outer peripheral surface of the exposed part of the rotating shaft 14, and the lower surface of the horizontal edge 1601 is abutted against the inner bottom wall of the groove 18 to prevent the transmission rod 16 from rotating downward. The abutment rod 17 is fixed to the side wall of one of the connecting sections (and the connecting section is the one away from the inclined section 402). The wedge-shaped surface of the vertical edge 1602 of the transmission rod 16 is located on the movement stroke of the abutment rod 17. The elastic force of the torsion spring makes the rotating shaft 14 have a tendency to rotate in the direction away from the baffle 12, thereby forcing the transmission rod 16 to rotate in the direction away from the baffle 12. The horizontal side 1601 of the movable rod 16 is in contact with the inner bottom wall of the groove 18. The purpose of such a setting is that when the two supporting plates 3 move in the direction away from each other, the guide rod 5 will be driven to move horizontally. During the movement, the abutment rod 17 will abut against the wedge-shaped surface of the vertical side 1602, thereby driving the transmission rod 16 and the rotating shaft 14 to rotate in the direction of the baffle 12, and then driving the push plate 13 to rotate in the direction of the baffle 12, and accumulating force in the torsion spring, so that the packaging bag is passively pushed down by the push plate 13 and leans against the baffle 12. After the packaging bag is sent away by the conveyor belt 1, the driving motor 6 drives the supporting plate 3 to move in the opposite direction, thereby driving the abutment rod 17 to move synchronously, and making the abutment rod 17 gradually move away from the wedge-shaped surface of the vertical side 1602. At this time, the elastic force of the torsion spring is gradually released to drive the push plate 13 to reset passively.

[0040] As another embodiment of the present invention, a plurality of reinforcing rods 19 are arranged on the bearing plate 3. Specifically, for a single bearing plate 3, three reinforcing rods 19 are arranged on one end thereof close to the center of the conveyor belt 1 (three reinforcing rods 19 are also arranged on the other bearing plate 3, and the reinforcing rods 19 on the two bearing plates 3 are arranged alternately), and three receiving grooves 20 are provided on the bearing plate 3 (the positions of which are arranged corresponding to the positions of the reinforcing rods 19 on the other bearing plate 3, and correspondingly, three receiving grooves 20 adapted to the reinforcing rods 19 are also provided on the other bearing plate 3), and the three reinforcing rods 19 are successively increased in the conveying direction of the conveyor belt 1, and the length of the longest reinforcing rod 19 is less than the horizontal movement distance of the bearing plate 3. The effect of such arrangement is that when the two bearing plates 3 are fitted with each other, the reinforcing rods 19 on the two bearing plates 3 are respectively inserted into the receiving grooves 20 opposite thereto, and when the bearing plate 3 moves horizontally, the reinforcing rods 19 are moved from the receiving grooves 20 to the receiving grooves 20. When the bag is pulled out from the groove 20, the reinforcing rod 19 will be driven to tilt synchronously during the subsequent tilting process of the carrying plate 3. Since the three reinforcing rods 19 increase successively on the conveying stroke of the conveyor belt 1, the side of the packaging bag close to the conveying stroke of the conveyor belt 1 will preferentially slide off the reinforcing rod 19 and contact the conveyor belt 1, that is, at this time, only one corner of the packaging bag is on the conveyor belt 1. During the conveying action of the conveyor belt 1 and the subsequent tilting process of the reinforcing rod 19, the packaging bag will slide off the middle reinforcing rod 19, and then slide off the longest reinforcing rod 19, so that the packaging bag gradually falls on the conveyor belt 1. The advantages brought by this are, firstly, under the action of the insertion of the reinforcing rod 19 and the accommodating groove 20, the overall strength of the carrying plate 3 can be improved, and secondly, the packaging bag can gradually fall on the conveyor belt 1, thereby improving the stability of the packaging bag when it is transferred to the conveyor belt 1.

[0041] Another embodiment of the present invention provides a vegetable seedling substrate prepared by the above-mentioned preparation device, comprising the following components: 40% of Chinese medicine residue, 20% of perlite, 20% of peat and 20% of coconut bran. During the fermentation process, the moisture content is controlled at 40%, the pH value is controlled at 5-7, and the EC value is controlled at 1000us±100.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
