Description

Technical Field

[0001] This application relates to the field of fertilization equipment technology, and in particular to a tree pit fertilization device and fertilization method for planting mixed camellia oleifera forests. Background Technology

[0002] Camellia oleifera is a small tree or shrub belonging to the Camellia genus of the Theaceae family. In the planting process of Camellia oleifera, it is necessary to use fertilization equipment to fertilize the planting pit before planting the Camellia oleifera tree.

[0003] Existing fertilization equipment mainly consists of an outer casing, an inner cylinder, a mixing component, and a discharge pipe. During use, various fertilizers (liquid and solid) are fed into the inner cylinder. Then, the mixing component is rotated to thoroughly mix the fertilizers, ensuring even distribution of fertilizer in the tree pits during subsequent fertilization. However, during this process, when solid fertilizers are mixed with liquid fertilizers, the solid fertilizers tend to stick together and clump together, making it difficult for them to mix effectively. This results in uneven distribution of fertilizer in each tree pit during subsequent fertilization, thus affecting the overall growth quality of the camellia trees. Summary of the Invention

[0004] This application proposes a tree pit fertilization device for planting mixed camellia oleifera forests, which has the advantage of promoting uniform mixing of fertilizers, thereby solving the problem that lumpy fertilizers affect the overall growth quality of camellia oleifera trees.

[0005] To achieve the above objectives, this application adopts the following technical solution: a tree pit fertilization device for planting mixed camellia oleifera forests, comprising: an outer casing, an inner cylinder disposed within the inner cavity of the outer casing, fixing members disposed on both sides of the inner cylinder, the inner cylinder being fixedly connected to the outer casing via the fixing members, a feed pipe disposed on one side of the upper side of the inner cylinder for conveying fertilizer into the inner cylinder, a discharge pipe disposed on the lower side of the inner cylinder for discharging the mixed fertilizer from the inner cylinder into the tree pit, a rotating shaft disposed at the center of the inner cavity of the inner cylinder, and a power mechanism fixedly disposed at the center of the upper side of the inner cylinder, the power mechanism being fixedly connected to the rotating shaft. A rotating ring is rotatably sleeved on the upper part of the outer side of the rotating shaft. A housing is rotatably sleeved on the outer side of the rotating ring. Stirring elements are circumferentially and equidistantly arranged on the outer side of the rotating shaft and below the housing. The upper end of the stirring element is fixedly connected to the housing, and the lower end of the stirring element is fixedly connected to the lower end of the rotating shaft. A collecting mechanism is provided on one side of the inner cylinder. The collecting mechanism is connected to the inner cylinder and is used to collect lumps of solid fertilizer. A transfer mechanism is provided on the upper side of the inner cylinder. The transfer mechanism connects the collecting mechanism and the rotating ring and transfers the lumps of solid fertilizer in the collecting mechanism to the inner cylinder, located inside the stirring elements.

[0006] Furthermore, the collecting mechanism includes a cavity and a baffle. The wall of the outer casing, the interior of one side fixing member, and the wall of the inner cylinder are connected to form a cavity. A baffle is provided in the cavity, and the baffle divides the cavity into a first cavity away from the stirring member and a second cavity close to the stirring member. The second cavity is connected to the inner cavity of the inner cylinder.

[0007] Furthermore, the transfer mechanism includes a conveying mechanism and a connecting pipe. The conveying mechanism is fixed on the upper side of the inner cylinder away from the feed pipe. A connecting pipe is provided between the outer casing and the inner cylinder. The connecting pipe consists of a first pipe and a second pipe. The upper end of the first pipe is connected to the input end of the conveying mechanism. The lower end of the first pipe is located on the bottom surface of the second cavity and is connected to the second cavity. The upper end of the second pipe is connected to the output end of the conveying mechanism. The lower end of the second pipe is fixedly connected to the rotating ring. The lower end of the second pipe is connected to a position inside the inner cylinder located inside the stirring element.

[0008] Furthermore, the baffle forms a sealed movable connection with the cavity, and a first telescopic rod is fixedly installed on one side of the outer casing corresponding to the cavity, with the output rod of the first telescopic rod forming a fixed connection with the baffle.

[0009] Furthermore, the baffle is provided with deflecting members at equal intervals on the side facing the stirring member, and a hinge shaft is provided at the upper part of the side of the baffle facing the stirring member. The upper end of the deflecting member is rotatably connected to the baffle through the hinge shaft. A telescopic mechanism is provided on one side of the baffle, and the telescopic mechanism is connected to the deflecting member to drive the deflecting member to deflect and reset.

[0010] Furthermore, the telescopic mechanism includes a power arc rod and an infusion mechanism. The power arc rod is movably and sealed inside the baffle. The end of the power arc rod facing the stirring component is fixedly connected to the deflector in the middle position. The end of the power arc rod facing away from the stirring component extends into the first cavity, which is filled with liquid medium. An infusion mechanism is fixedly installed on the side of the outer casing and below the first telescopic rod. The output end of the infusion mechanism is connected to the second cavity.

[0011] Furthermore, the telescopic mechanism is a second telescopic rod, and the second telescopic rod is fixedly installed on the side of the baffle facing away from the stirring component. The second telescopic rod has an arc-shaped structure, and the output rod of the second telescopic rod is fixedly connected to the deflection component in the middle position.

[0012] Furthermore, the baffle has an arc-shaped structure, and the curvature of the side of the baffle facing the stirring component is equal to the curvature of the inner wall of the inner cylinder.

[0013] A method for fertilizing tree pits in mixed camellia oleifera forests includes the following steps:

[0014] The first step is to use an excavator to dig a tree pit at the designated location;

[0015] The second step is to feed the liquid fertilizer and solid fertilizer into the inner cylinder so that the fertilizer is mixed evenly by the fertilization equipment.

[0016] The third step is to move the fertilization equipment to the tree pit and deliver the fertilizer inside into the tree pit.

[0017] The fourth step is to remove the fertilization equipment and plant the camellia seedlings in the planting pit. Then, have an excavator cover the planting pit with the excavated soil so that the roots of the camellia seedlings are in the soil.

[0018] This application has the following beneficial effects:

[0019] This application provides a tree pit fertilization device for planting mixed camellia oleifera forests. Through the arrangement of a stirring element, a cavity, and a connecting pipe, the stirring element drives the liquid fertilizer and solid fertilizer to rotate, so that some of the liquid fertilizer and lumps of solid fertilizer enter the cavity and are transported through the connecting pipe into the area surrounded by the stirring element. This process is repeated, and through the above actions, the lumps of solid fertilizer are broken up, thereby improving the mixing effect of the fertilizer.

[0020] With the baffle and deflector, during the process of the lumpy fertilizer entering the cavity, the deflector will reciprocate to deflect and reset. When the deflector deflects, it will extend into the inner cylinder and come into contact with the rotating liquid flow driven by the agitator. Through the above actions, the lumpy fertilizer in the liquid flow will collide with the deflector, thereby causing the lumpy fertilizer to break up and improving the mixing effect of the fertilizer.

[0021] By setting up baffles and deflectors, when the deflectors are reset, they will apply compressive force to the lumps of fertilizer in the cavity, thereby causing the lumps of fertilizer to break up and further improving the mixing effect of the fertilizer. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Example 1

[0033] Please see Figure 1 and Figure 2A tree pit fertilization device for planting mixed camellia oleifera forests includes an outer casing 1 with wheels on its lower side. An inner cylinder 2 is housed within the outer casing 1, with fixing members 3 on both sides of the inner cylinder 2. The inner cylinder 2 is welded to the outer casing 1 via the fixing members 3. A feed pipe 4 is located on one side of the upper side of the inner cylinder 2, with its upper end connected to the external environment and its lower end connected to the inner cavity of the inner cylinder 2. A discharge pipe 5 is located on the lower side of the inner cylinder 2, with its upper end connected to the inner cavity of the inner cylinder 2. The lower end of the discharge pipe 5 is located on the lower side of the outer casing 1. An electric control switch is installed inside the discharge pipe 5 to control its connection and closure. A rotating shaft 6 is located at the center of the inner cavity of the inner cylinder 2. A power mechanism (such as a motor) is fixed at the center of the upper side of the inner cylinder 2. The output shaft of the power mechanism is welded to the upper end of the rotating shaft 6. A rotating ring 7 is rotatably sleeved on the upper part of the outer side of the rotating shaft 6. An outer casing 8 is rotatably sleeved on the outer side of the rotating ring 7. A stirring element 9 is circumferentially and equidistantly arranged on the outer side of the rotating shaft 6 and below the outer casing 8. The agitator 9 is configured with a bent structure. The upper end of the agitator 9 is welded and fixed to the outer shell 8, and the lower end of the agitator 9 is welded and fixed to the lower end of the rotating shaft 6. The wall of the outer casing 1, the interior of the fixing member 3 on one side, and the wall of the inner cylinder 2 are connected to form a cavity 10. The opening of the cavity 10 is connected to the inner cavity of the inner cylinder 2. A baffle 11 is provided in the cavity 10, which divides the cavity 10 into a first cavity away from the agitator 9 and a second cavity close to the agitator 9. The second cavity is connected to the inner cavity of the inner cylinder 2. The upper side of the inner cylinder 2 and the position away from the feed pipe 4 A transfer mechanism 12 (such as a water pump) is fixedly installed. A connecting pipe 13 is provided between the outer casing 1 and the inner cylinder 2. The connecting pipe 13 consists of a first pipe and a second pipe. The upper end of the first pipe is connected to the input end of the transfer mechanism 12. The lower end of the first pipe is located on the bottom surface of the second cavity and is connected to the second cavity. The upper end of the second pipe is connected to the output end of the transfer mechanism 12. The lower end of the second pipe extends into the inner cylinder 2 and passes through the rotating ring 7. The lower end of the second pipe is fixedly connected to the rotating ring 7. The lower end of the second pipe is connected to the position inside the stirring element 9 in the inner cylinder 2.

[0034] In use, various fertilizers (liquid and solid) are fed into the inner cylinder 2 through the feed pipe 4. Then, the power mechanism drives the rotating shaft 6 to rotate, causing the stirring element 9 to rotate synchronously. This causes the fertilizers in the inner cylinder 2 to form a rotating liquid flow (the amount of liquid fertilizer exceeds the amount of solid fertilizer). Due to the large mass of the solid fertilizer clumps, these clumps are subjected to centrifugal force from the rotating liquid flow and are thrown into the second chamber (some liquid fertilizer enters the second chamber simultaneously). They then collide with the baffle 11, breaking up the solid fertilizer clumps and improving the mixing effect of the subsequent fertilizers. Simultaneously, the transfer mechanism 12 is activated, allowing the fertilizers entering the inner cylinder 2 to flow smoothly. The lumpy fertilizer and some liquid fertilizer in the second chamber are transported through the first pipe, the transfer mechanism 12 and the second pipe, and then enter the area surrounded by the mixing element 9 (because the rotating ring 7 is fixed by the second pipe, it will not rotate synchronously with the rotation of the mixing element 9 and the rotating shaft 6), and move to the outer position of the mixing element 9. This process is repeated to increase the contact probability between the lumpy fertilizer and the mixing element 9, causing the lumpy solid fertilizer to break up, thereby improving the mixing effect of the fertilizer. After the fertilizer is mixed, the power mechanism and the transfer mechanism 12 are stopped, and the discharge pipe 5 is opened, so that the fertilizer in the inner cylinder 2 enters the tree pit through the discharge pipe 5, thereby completing the fertilization operation.

[0035] Please see Figure 1 and Figure 2 A baffle 11 is slidably installed in the cavity 10. A telescopic rod 14 (such as the combination of an electric telescopic cylinder and an output rod in the prior art) is fixedly installed on one side of the outer casing 1 corresponding to the cavity 10. The output rod of the telescopic rod 14 extends into the cavity and is welded to the baffle 11.

[0036] During the process of the lumpy fertilizer entering the second cavity, the first telescopic rod 14 drives the baffle 11 to move back and forth in the cavity (the baffle 11 will not cross the first pipe), so that the baffle 11 pushes the lumpy fertilizer entering the second cavity, thereby reducing the probability of the lumpy fertilizer settling and accumulating in the second cavity, making it less likely for the lumpy fertilizer to clog the first pipe. Then, when the mixing time of the fertilizer in the inner cylinder 2 is about to be reached, the first telescopic rod 14 drives the baffle 11 to cross the first pipe and overlap with the wall of the inner cylinder 2. Through the above actions, fertilizer residue in the second cavity is avoided, which would reduce the utilization rate of the fertilizer (the time when the transfer mechanism 12 stops running is after the time when the baffle 11 overlaps with the wall of the inner cylinder 2).

[0037] Please see Figures 1-3A deflector 15 is equidistantly arranged on the side of the baffle 11 facing the agitator 9. A hinge shaft is provided on the upper part of the side of the baffle 11 facing the agitator 9. The upper end of the deflector 15 is rotatably connected to the baffle 11 through the hinge shaft. The side of the deflector 15 facing the baffle 11 is a conical surface. A power arc rod 16 is slidably installed inside the baffle 11. The end of the power arc rod 16 facing the agitator 9 is welded and fixed to the deflector 15 in the middle position. The end of the power arc rod 16 facing away from the agitator 9 extends into the first cavity. The first cavity is filled with liquid medium (such as hydraulic oil). A liquid delivery mechanism 17 (such as a combination of a liquid delivery pump and a container for storing liquid medium) is fixedly installed on the side of the outer casing 1 below the first telescopic rod 14. The output end of the liquid delivery mechanism 17 is connected to the second cavity.

[0038] During the reciprocating movement of the baffle 11 driven by the first telescopic rod 14, when the baffle 11 moves away from the stirring member 9, the pressure in the first chamber increases, causing the liquid medium to push the power arc rod 16 into the second chamber and drive the deflector 15 to deflect, so that the lower part of the deflector 15 extends into the inner cylinder 2 and contacts the rotating liquid flow driven by the stirring member 9. Through the above actions, the lumps of fertilizer in the liquid flow collide with the deflector 15, thereby causing the lumps of fertilizer to break up and improving the mixing effect of the fertilizer. Afterwards, when the baffle 11 returns to its original position, the pressure in the first chamber decreases, causing the power arc rod 16 to drive the deflector 15 to return to its original position. The returned deflector 15 contacts the lumps of fertilizer in the second chamber, causing the fertilizer to be crushed. Through the above actions, the mixing effect of the fertilizer is further improved. In addition, when the first telescopic rod 14 drives the baffle 11 to overlap with the wall of the inner cylinder 2, the liquid delivery mechanism 17 delivers liquid medium into the first chamber, allowing the baffle 11 to move smoothly.

[0039] A method for fertilizing tree pits in mixed camellia oleifera forests includes the following steps:

[0040] The first step is to use an excavator to dig a tree pit at the designated location;

[0041] The second step is to feed the liquid fertilizer and solid fertilizer into the inner cylinder 2 so that the fertilizer is evenly mixed by the fertilization equipment.

[0042] The third step is to move the fertilization equipment to the tree pit and deliver the fertilizer inside into the tree pit.

[0043] The fourth step is to remove the fertilization equipment and plant the camellia seedlings in the planting pit. Then, have an excavator cover the planting pit with the excavated soil so that the roots of the camellia seedlings are in the soil.

[0044] Example 2

[0045] Please see Figure 4 and Figure 5This embodiment is a further improvement based on the first embodiment. The improvement is that a second telescopic rod 18 (such as the combination of an electric telescopic cylinder and an output rod in the prior art) is fixedly installed on the side of the baffle 11 facing away from the stirring component 9. The second telescopic rod 18 has an arc-shaped structure. The output rod of the second telescopic rod 18 passes through the baffle 11 and is welded to the deflector 15 in the middle position. A vent hole is opened inside the outer box 1, which connects the external environment with the first chamber.

[0046] During the reciprocating movement of the baffle 11 driven by the first telescopic rod 14, the second telescopic rod 18 drives the deflector 15 to reciprocate and reset, so that the lower part of the deflector 15 extends into the inner cylinder 2 and comes into contact with the rotating liquid flow driven by the agitator 9, causing the lumps of fertilizer in the liquid flow to collide with the deflector 15. Then, the deflector 15 contacts the lumps of fertilizer in the second cavity, causing the fertilizer to be crushed.

[0047] Example 3

[0048] Please see Figure 1 and Figure 6 This embodiment is a further improvement on embodiment one or two. The improvement is that the baffle 11 has an arc-shaped structure, and the arc of the side of the baffle 11 facing the stirring component 9 is equal to the arc of the inner wall of the inner cylinder 2.

[0049] With the above settings, when the baffle 11 overlaps with the wall of the inner cylinder 2, there will be no dead corner, thereby improving the utilization rate of fertilizer. In addition, when the lumpy fertilizer enters the second cavity and comes into contact with the baffle 11, the lumpy fertilizer will move along the arc surface of the baffle 11, so that the lumpy fertilizer passing through the deflector 15 will not be inside the second cavity and there will be a gap at the position of the deflector 15, thereby increasing the probability of the deflector 15 coming into contact with the lumpy fertilizer in the future.
