Technical Field
[0001] The present application relates to the technical field of root embedding granular medicine equipment, and more specifically, to a quantitative root embedding medicine applicator. Background Art
[0002] At present, a root buried granular medicine application equipment is used for tree fertilization. Compared with the previous root application method of digging a pit first, then putting the granular medicine into the pit, and finally backfilling the soil, the application equipment can also use the equipment to guide the granular medicine into the pit after digging the pit, without the need for additional medicine taking and placing operations. The equipment can be operated by one person, thereby improving the efficiency of medicine application. However, the current root buried granular medicine application equipment relies on manual opening and closing of a single valve to control the amount of medicine applied, and cannot rely on the equipment itself to perform quantitative medicine application with a certain degree of accuracy. Utility Model Content
[0003] In view of the problem that the current root buried granular medicine application equipment relies on manual opening and closing of a single valve to control the application amount and cannot rely on the equipment itself to perform quantitative application with a certain degree of accuracy, this application proposes a quantitative root buried medicine applicator and adopts the following technical solution.
[0004] A quantitative root-embedded drug applicator comprises a fixed handle, a spade tube, a spade head and a quantitative mechanism. One end of the spade tube is connected to the fixed handle, and the other end is connected to the spade head; the end of the spade tube connected to the spade head remains open, and the opening is a lower outlet; the side wall of the spade tube has a fertilizer inlet. The quantitative mechanism comprises a trigger handle, a first fiber rope, a first cover plate, a rebound member, a second fiber rope, a second cover plate and a swivel member. The first cover plate is rotatably installed in the spade tube; the first cover plate is located below the fertilizer inlet. The trigger handle connects one end of the first fiber rope and one end of the second fiber rope; the other end of the first fiber rope penetrates the spade tube and is fixed to one side of the first cover plate; the two ends of the rebound member connect the other side of the first cover plate and the inner wall of the spade tube. The swivel member is installed at the lower outlet; the second cover plate is connected to the swivel member; the other end of the second fiber rope is fixed to the second cover plate. The first state of the quantitative root embedding drug applicator is that the first cover plate does not cut off the inner cavity channel of the spade tube, and the second cover plate covers the lower outlet under the action of the rotating member. The trigger handle is driven to pull the first fiber rope and the second fiber rope respectively, so that the quantitative root embedding drug applicator can be transformed from the first state to the second state, and the second state is that the first cover plate cuts off the inner cavity channel of the spade tube, and the second cover plate releases the cover on the lower outlet.
[0005] By adopting the above technical solution, the rebound member has a tendency to drive the first cover plate to open the inner channel of the spade tube, and the rotating member has a tendency to drive the second cover plate to close the lower outlet. When the trigger handle is not driven to pull the first fiber rope and the second fiber rope, the quantitative root buried medicine applicator is in the first state, that is, the first cover plate does not cut off the inner cavity channel of the spade tube, and the second cover plate covers the lower outlet under the action of the rotating member. At this time, granular medicine can be injected between the first cover plate and the second cover plate. When a pit is dug out with the spade head, and the trigger handle is held to pull the first fiber rope and the second fiber rope, the quantitative root buried medicine applicator is in the second state, that is, the first cover plate cuts off the inner cavity channel of the spade tube, and the second cover plate releases the cover of the lower outlet. At this time, the granular medicine between the first cover plate and the second cover plate can flow downward into the pit that has been shoveled open. The amount of medicine applied each time is the granular medicine stored between the first cover plate and the second cover plate, which basically achieves the effect of quantitative application.
[0006] A preferred embodiment of the quantitative root embedding drug applicator is as follows: a section of the spade tube between the first cover plate and the second cover plate is a square tube, the first cover plate and the second cover plate are both square plates, and are configured so that the first cover plate can adaptably cut off the inner cavity channel of the spade tube, and the second cover plate can adaptably cover the lower outlet.
[0007] By adopting the above technical solution, the combination of the square tube and the square plate can allow the first cover plate and the second cover plate to rotate basically without hindrance.
[0008] A preferred embodiment of the quantitative root embedding drug applicator is as follows: the quantitative mechanism also includes a seat plate; the seat plate is square and vertically connected to the inner wall of the spade tube; the three sides of the seat plate seamlessly fit the three inner wall surfaces of the spade tube; the first cover plate is rotatably connected to the fourth side of the seat plate; and the rebound member is arranged at a position adjacent to the seat plate.
[0009] By adopting the above technical solution, a seat plate is provided to provide a lateral space for the installation of the resilient member.
[0010] A preferred embodiment of the quantitative root embedding drug applicator is that along the width direction of the spade tube, the width of the seat plate is less than one third of the inner width of the spade tube.
[0011] By adopting the above technical solution, a wider channel is retained in the spade tube.
[0012] A preferred embodiment of the quantitative root embedding drug applicator is that the distance L1 from the point P where the rebound member connects to the first cover plate to the base plate is less than one quarter of the distance L2 from P to the end of the first cover plate away from the base plate.
[0013] By adopting the above technical solution, after the first cover plate rotates, the resilient member is stretched to a shorter length, that is, the resilient member can be designed to be shorter, thereby retaining a wider passage inside the spade pipe.
[0014] A preferred embodiment of the quantitative root embedment drug applicator is as follows: the rotating part is a convex torsion spring, and the convex torsion spring has an elastic lug; the quantitative root embedment drug applicator also includes a sleeve; the sleeve is fixed on the outer wall of the spade tube; the convex torsion spring is installed in the sleeve, and the convex torsion spring has two end points fixed on the sleeve; the sleeve is provided with a making way opening for the lug; the lug extends out of the making way opening; and the second cover plate is fixed to the lug.
[0015] By adopting the above technical solution, the convex torsion spring can drive the second cover plate to be close to the lower outlet. When the second cover plate is pulled to open the lower outlet and the pulling force is removed, the convex torsion spring can drive the second cover plate to be close to the lower outlet again.
[0016] A preferred embodiment of the quantitative root embedding drug applicator is as follows: the convex torsion spring has two elastic lugs; the shaft sleeve is provided with two paving openings for paving the two lugs; the second fiber rope is wound around the position between the two paving openings and connected to the bottom surface of the second cover plate.
[0017] By adopting the above technical solution, the second fiber rope can avoid the yield opening, reducing the risk of scratching or breaking the second fiber rope.
[0018] A preferred embodiment of the quantitative root embedding drug applicator is as follows: the fixed handle has a double-layer clamp seat, a pin and a torsion spring; the trigger handle has a through hole; the pin passes through the through hole and the spring; both ends of the pin are fixed to the double-layer clamp seat; the trigger handle fixes one end of the torsion spring; and the other end of the spring is fixed to the double-layer clamp seat.
[0019] By adopting the above technical solution, the trigger handle can be installed on the fixed handle in a manually rotatable and automatically revolving manner, so that the trigger handle can pull the first fiber rope and the second fiber rope, and the trigger handle can also be automatically reset.
[0020] A preferred embodiment of the quantitative root-embedded medicine applicator is as follows: a first block and a second block are fixedly provided on the inner wall of the shovel tube; the first cover plate is driven by the first fiber rope to abut against the lower surface of the first block, so that the quantitative root-embedded medicine applicator is in the second state; the second cover plate is driven by the rotating member to abut against the lower surface of the second block, so that the quantitative root-embedded medicine applicator is in the first state.
[0021] By adopting the above technical solution, when the first cover plate is pulled by the first fiber rope, the first cover plate is used with the maximum force to completely close the internal passage of the spade pipe without the need for precise control of the external force. When the convex torsion spring drives the second cover plate to twist, the second cover plate can just completely close the lower entrance.
[0022] A preferred embodiment of the quantitative root embedding drug applicator is as follows: the first fiber rope includes a first core wire and a first sleeve; the first core wire is inserted into the first sleeve, and the two ends of the first core wire extend out of the first sleeve; one end of the first core wire is fixedly connected to the trigger handle, and the other end is fixedly connected to the upper surface of the first cover; the two ends of the first sleeve are fixed to the fixed handle and / or the spade pipe. The second fiber rope includes a second core wire and a second sleeve; the second core wire is inserted into the second sleeve, and the two ends of the second core wire extend out of the second sleeve; one end of the second core wire is fixedly connected to the trigger handle, and the other end is fixedly connected to the lower surface of the second cover; the two ends of the second sleeve are fixed to the fixed handle and / or the spade pipe.
[0023] By adopting the above technical solution, the first sleeve and the second sleeve are fixed respectively, so that the pulling distance of the first core wire and the second core wire can be accurately controlled.
[0024] In summary, the quantitative root buried medicine applicator of the present application has the following beneficial effects: the rebound member has a tendency to drive the first cover plate to open the inner channel of the spade tube, and the rotating member has a tendency to drive the second cover plate to close the lower outlet. When the trigger handle is not driven to pull the first fiber rope and the second fiber rope, the quantitative root buried medicine applicator is in the first state, that is, the first cover plate does not cut off the inner cavity channel of the spade tube, and the second cover plate covers the lower outlet under the action of the rotating member. At this time, granular medicine can be injected between the first cover plate and the second cover plate. When a pit is dug out with the spade head, and the trigger handle is held to pull the first fiber rope and the second fiber rope, the quantitative root buried medicine applicator is in the second state, that is, the first cover plate cuts off the inner cavity channel of the spade tube, and the second cover plate releases the cover of the lower outlet.

DETAILED DESCRIPTION
[0035] The quantitative root buried medicine applicator of the present application is described in detail below with reference to the accompanying drawings.
[0036] Please refer to Figure 1 A quantitative root buried medicine applicator comprises a fixed handle 1, a spade tube 2, a spade head 3 and a quantitative mechanism.
[0037] The fixed handle 1 can be a section of round steel pipe, and the shovel pipe 2 can be a section of square steel pipe. One end of the shovel pipe 2 is vertically fixed at the middle position of the fixed handle 1. The other end of the shovel pipe 2 is connected to the shovel head 3. The shovel head 3 can be triangular, with the tip facing downward, so as to facilitate digging a hole in the soil.
[0038] The lower end of the spade pipe 2 can be connected to the spade head 3 via a downwardly extending segment, so that the lower end of the spade pipe 2 remains open, and the opening is the lower outlet 201 .
[0039] The side wall of the spade pipe 2 is provided with a fertilizer inlet 202. A fork pipe 4 extending obliquely upward can also be provided on the spade pipe 2, and the fork pipe 4 is connected to the fertilizer inlet 202 of the spade pipe 2.
[0040] The quantitative root buried medicine applicator also includes a fertilizer pipe 5 and a fertilizer bucket 6. One end of the fertilizer pipe 5 is connected to the bottom of the fertilizer bucket 6, and the other end is connected to the fork pipe 4, and the fertilizer pipe 5 and the fork pipe 4 are fixed by a clamp. The fertilizer pipe 5 is a section of a hose, and a suitable length of the fertilizer pipe 5 is set, so that when a person carries the fertilizer bucket 6, the fertilizer pipe can continue to drop in height from one end connected to the fertilizer bucket 6 to one end connected to the fork pipe 4, so that under the action of gravity, the applicator can automatically discharge the granular medicine. If the fork pipe 4 is not provided, the fertilizer pipe 5 can be directly connected to the fertilizer inlet 202. The fertilizer bucket 6 is provided with a shoulder strap, and the granular medicine can be loaded inside the fertilizer bucket 6.
[0041] Please refer to Figure 2 The quantitative mechanism includes a trigger handle 7, a first fiber rope 8, a first cover plate 9, a rebound member 10, a second fiber rope 11, a second cover plate 12 and a rotating member 13.
[0042] The first cover plate 9 is rotatably installed in the shovel tube 2; the first cover plate 9 is located below the fertilizer inlet 202.
[0043] The trigger handle 7 is rotatably connected to the lower part of the fixed handle 1, and the distance between the trigger handle 7 and the fixed handle 1 should be set so that the trigger handle 7 and the fixed handle 1 can be held simultaneously with one hand.
[0044] The first fiber rope 8 may include a first core wire 801 and a first sleeve 802. The first core wire 801 is inserted into the first sleeve 802, and both ends of the first core wire 801 extend out of the first sleeve 802. One end of the first sleeve 802 is fixed to the fixed handle 1, and the other end is fixed to the outer wall of the spade pipe 2.
[0045] The second fiber rope 11 may include a second core wire 1101 and a second sleeve 1102. The second core wire 1101 is inserted into the second sleeve 1102, and both ends of the second core wire 1101 extend out of the second sleeve 1102. One end of the second sleeve 1102 is fixed to the fixed handle 1, and the other end is fixed to the outer wall of the spade pipe 2.
[0046] like Figure 1 The trigger handle 7 connects one end of the first fiber rope 8 and one end of the second fiber rope 11. Specifically, the trigger handle 7 connects the first core wire 801 and the second core wire 1101. The other end of the first fiber rope 8 passes through the spade tube 2 and is fixed to one side of the first cover plate 9. Specifically, the first core wire 801 is fixed to the upper surface of the first cover plate 9 by the first bolt 14.
[0047] Please refer to Figure 3The rebound member 10 can be a straight spring, and its two ends are connected to the lower surface of the first cover plate 9 and the inner wall of the spade tube 2.
[0048] Please refer to Figure 4 The rotating member 13 can be a torsion spring installed at the lower outlet 201. The second cover plate 12 is connected to the rotating member 13.
[0049] Please refer to Figure 5 The other end of the second fiber rope 11 is fixed to the second cover plate 12 , and specifically, the second core wire 1101 is fixed to the lower surface of the second cover plate 12 by a second bolt 15 .
[0050] Please refer to Figure 2 The first state of the quantitative root embedding drug applicator is that the first cover plate 9 does not cut off the inner cavity channel of the spade tube 2, and the second cover plate 12 covers the lower outlet 201 under the action of the rotating member 13.
[0051] Please refer to Figure 6 , drive the trigger handle 7, that is, hold the trigger handle 7, and make the trigger handle 7 close to the fixed handle 1 to pull the first fiber rope 8 and the second fiber rope 11 respectively, so that the quantitative root embedding agent applicator can be transformed from the first state to the second state. The second state is: the first cover plate 9 cuts off the inner cavity channel of the spade tube 2, and the second cover plate 12 releases the cover on the lower outlet 201.
[0052] In the quantitative root embedment medicine applicator, the rebound member 10 tends to drive the first cover plate 9 to open the inner channel of the spade tube 2, and the rotating member 13 tends to drive the second cover plate 12 to close the lower outlet 201. When the trigger handle 7 is not driven to pull the first fiber rope 8 and the second fiber rope 11, the quantitative root embedment medicine applicator is in the first state, that is, the first cover plate 9 does not cut off the inner cavity channel of the spade tube 2, and the second cover plate 12 covers the lower outlet 201 under the action of the rotating member 13. At this time, granular medicine can be injected between the first cover plate 9 and the second cover plate 12. When a pit is dug out with the shovel head 3 and the trigger handle 7 is held to pull the first fiber rope 8 and the second fiber rope 11, the quantitative root buried medicine applicator is in the second state, that is, the first cover plate 9 cuts off the inner cavity channel of the shovel tube 2, and the second cover plate 12 releases the cover on the lower outlet 201. At this time, the granular medicine between the first cover plate 9 and the second cover plate 12 can flow downward into the shoveled pit. The amount of medicine applied each time is the granular medicine stored between the first cover plate 9 and the second cover plate 12, which basically achieves the effect of quantitative application.
[0053] In order to allow the first cover plate 9 and the second cover plate 12 to rotate substantially unhindered, the section of the spade tube 2 between the first cover plate 9 and the second cover plate 12 may be a square tube, or the spade tube 2 may be a square tube as a whole, and the first cover plate 9 and the second cover plate 12 may be square plates, and the first cover plate 9 and the second cover plate 12 may be configured such that the first cover plate 9 can adaptably cut off the inner cavity channel of the spade tube 2, and the second cover plate 12 can adaptably cover the lower outlet 201. In other embodiments, the section of the spade tube 2 between the first cover plate 9 and the second cover plate 12 may be a triangular tube, and the first cover plate 9 and the second cover plate 12 may be triangular plates, etc., which can also allow the first cover plate 9 and the second cover plate 12 to rotate substantially unhindered.
[0054] Since the section of the spade pipe 2 between the first cover plate 9 and the second cover plate 12 is a square pipe, the first cover plate 9 and the second cover plate 12 are both square plates. Figure 3 In a preferred embodiment, the quantitative mechanism further comprises a seat plate 16, which is square and vertically connected to the inner wall of the spade tube 2. The three sides of the seat plate 16 are seamlessly attached to the three inner wall surfaces of the spade tube 2; the first cover plate 9 is rotatably connected to the fourth side of the seat plate 16; and the resilient member 10 is arranged at a position adjacent to the seat plate 16. The seat plate 16 is arranged to provide a lateral space for the installation of the resilient member 10.
[0055] Along the width direction of the spade tube 2 , the width of the seat plate 16 is less than one third of the inner width of the spade tube 2 , so that a wider granular medicine flow channel is retained in the spade tube 2 .
[0056] Please refer to Figure 7 The distance L1 from the point P where the rebound member 10 connects to the first cover plate 9 to the seat plate 16 is less than one-fourth of the distance L2 from P to the end of the first cover plate 9 away from the seat plate 16, so that after the first cover plate 9 rotates, the stretched length of the rebound member 10 is shorter, that is, the rebound member 10 can be designed to be shorter, thereby retaining a wider channel inside the shovel tube 2.
[0057] The rotating member 13 described above is installed at the lower outlet 201, and the second cover plate 12 is connected to the rotating member 13. Specifically, the rotating member 13 is a convex torsion spring, and the convex torsion spring has an elastic lug 1301. The lug 1301 can be square or arched. The quantitative root embedding drug applicator also includes a sleeve 17; the sleeve 17 is fixed on the outer wall surface of the spade tube 2; the convex torsion spring is installed in the sleeve 17, and the convex torsion spring has two end points fixed on the sleeve 17.
[0058] Please refer to Figure 8 The shaft sleeve 17 is provided with a clearance opening 1701 for the lug 1301; the lug 1301 extends out of the clearance opening 1701; the second cover plate 12 is fixed to the lug 1301. The convex torsion spring can drive the second cover plate 12 to be close to the lower outlet 201. When the second cover plate 12 is pulled to open the lower outlet 201, and the pulling force is removed, the convex torsion spring can drive the second cover plate 12 to be close to the lower outlet 201 again.
[0059] Further preferably, the convex torsion spring has two elastic lugs 1301; the sleeve 17 has two make way openings 1701 for the two lugs 1301; the second fiber rope 11 is wound around a position between the two make way openings 1701 and connected to the bottom surface of the second cover plate 12, so that the second fiber rope 11 can avoid the make way openings 1701, thereby reducing the risk of scratching or breaking the second fiber rope 11.
[0060] Please refer to Fig. 9 In order to allow the trigger handle 7 to automatically reset, the fixed handle 1 is designed to have a double-layer clamp seat 101, a pin 102 and a torsion spring 18; the trigger handle 7 is provided with a through hole; the pin 102 passes through the through hole and the spring; both ends of the pin 102 are fixed to the double-layer clamp seat 101; the trigger handle 7 fixes one end of the torsion spring 18; the other end of the spring is fixed to the double-layer clamp seat 101. The trigger handle 7 can be manually rotated and automatically rotated on the fixed handle 1, so that the trigger handle 7 can pull the first fiber rope 8 and the second fiber rope 11, and the trigger handle 7 can also automatically reset.
[0061] The inner wall of the shovel tube 2 is fixedly provided with a first stopper 203 and a second stopper 204; the first cover plate 9 is driven by the first fiber rope 8 to abut against the lower surface of the first stopper 203, so that the quantitative root embedment medicine applicator is in the second state; the second cover plate 12 is driven by the rotating member 13 to abut against the lower surface of the second stopper 204, so that the quantitative root embedment medicine applicator is in the first state.
[0062] Since the inner wall of the spade tube 2 is fixedly provided with the first stopper 203, when the first cover plate 9 is pulled by the first fiber rope 8, the first cover plate 9 can be used to completely close the internal passage of the spade tube 2 with the maximum force without the need for precise control of the external force.
[0063] Since the second stopper 204 is fixedly provided on the inner wall of the spade tube 2, when the convex torsion spring drives the second cover plate 12 to twist, the second cover plate 12 can just completely close the lower inlet.
[0064] One way to use the quantitative root buried drug applicator of the above embodiment is that a person carries the fertilizer bucket 6 on his back, holds the fixed handle 1, and places the shovel head 3 on the soil. At this time, the first cover plate 9 is opened, that is, the inner channel of the shovel tube 2 is opened, and the second cover plate 12 closes the lower outlet 201. Since the fertilizer bucket 6 is in a high position, the fertilizer tube 5 is connected downward to the fork tube 4 in a low position (or directly connected to the shovel tube 2). Under the action of gravity, the granular medicine in the fertilizer bucket 6 flows downward into the shovel tube 2. Press the fixed handle 1 downward to bury the tip of the shovel head 3 in the soil, and move the fixed handle 1 forward horizontally to form a soil pit. At this time, hold the fixed handle 1 and the trigger handle 7 tightly, that is, pull the trigger handle 7 upward. At this time, the first cover plate 9 closes the inner channel of the shovel tube 2, and the second cover plate 12 is opened. The granular medicine between the first cover plate 9 and the second cover plate 12 flows into the soil pit through the lower outlet 201, completing the application action. This process is repeated, and the amount of medicine applied each time is basically the amount of granular medicine stored between the first cover plate 9 and the second cover plate 12, thereby basically achieving the effect of quantitative medicine application.
[0065] The above are only some embodiments of the present application, and the protection scope of the present application is not limited to the above embodiments. For ordinary technicians in this technical field, several improvements and modifications without departing from the creative design of the present application should also fall within the protection scope required by the present application.
