The existing fertilization method generally makes holes in the soil, and then manually holds the fertilizer and pours the fertilizer beside the holes. This fertilization method not only has low efficiency, but also has different effects on the absorption effect of plants because the depth, shape and position of the holes are difficult to control. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a ring-hole fertilizing device to greatly improve the fertilization efficiency.

[0004] In order to solve the above technical problem, the technical solution adopted by the utility model is as follows:

[0005] A ring-hole fertilizing device includes a housing, a traction assembly, a hole-making cone, a fertilizer-distributing mechanism and a fertilizing mechanism;

[0006] The fertilizer-distributing mechanism is connected to the hole-making cone through a connecting rod, and the axial direction of the hole-making cone is perpendicular to the axial direction of the connecting rod, so that the fertilizer-distributing mechanism and the hole-making cone can synchronously perform circular motion;

[0007] When the fertilizer-distributing mechanism pushes the control end of the fertilizing mechanism to rotate, the discharge port of the fertilizing mechanism is opened, and the feed port of the fertilizer-distributing mechanism is oppositely arranged with the discharge port of the fertilizing mechanism;

[0008] The fertilizer-distributing mechanism has a main body and a bin door assembly, and the bin door assembly is slidably connected to the main body to form a bin for accommodating fertilizer;

[0009] One end of the traction assembly is connected to the bin door assembly, and the other end of the traction assembly is connected to the housing. When the traction assembly is in a tension state, the bin is opened to allow the fertilizer to fall.

[0010] Further, the bin door assembly includes a pressure rod, a spring and a blocking member arranged around the main body;

[0011] The traction assembly is connected to the first control end of the pressure rod;

[0012] The pressure rod is slidably connected to the main body, and the spring is sleeved outside the pressure rod and is clamped between the main body and the second control end of the pressure rod in the axial direction of the pressure rod;

[0013] The blocking member and the main body form the bin, and the blocking member is in transmission connection with the second control end of the pressing rod. When the spring is compressed, the bin is opened.

[0014] Further, the main body includes a feeding hopper and a blanking cavity arranged in sequence along the axis;

[0015] The feeding hopper is communicated with the blanking cavity, and the blocking member covers outside the blanking cavity to form the bin.

[0016] Further, the blanking cavity has a guiding inclined surface that gradually sinks in the direction away from the feeding hopper.

[0017] Further, the traction assembly includes a support column and a traction rope;

[0018] The support column is connected to the housing, one end of the traction rope is connected to the support column, and the other end is in transmission connection with the pressing rod of the bin door assembly.

[0019] Further, the fertilizing mechanism includes a storage hopper, a discharger, a partition member, and a toothed member;

[0020] The storage hopper is communicated with the discharger, the partition member is installed in the discharger and forms at least four discharge grooves that are evenly distributed circumferentially along the toothed member;

[0021] The toothed member is in transmission connection with the partition member, and the toothed member is arranged outside the discharger.

[0022] Further, a pushing member is arranged at the feeding end of the fertilizer spreading mechanism, and the pushing member can abut against the toothed member and push the toothed member to rotate.

[0023] Further, a driving mechanism is further included; the driving mechanism includes a first transmission assembly and a second transmission assembly that operate synchronously;

[0024] The first transmission assembly is in transmission connection with the fertilizer spreading mechanism, the second transmission assembly is in transmission connection with the hole punching cone, the first transmission assembly is used to drive the fertilizer spreading mechanism to make a circular motion, and the second transmission assembly is used to drive the hole punching cone to make a circular motion.

[0025] The beneficial effects of the present utility model are as follows: By setting up a fertilizer distribution mechanism and a hole punching cone, the fertilizer distribution mechanism and the hole punching cone perform circular motion and move forward synchronously. After the hole punching cone punches holes first, the fertilizer distribution mechanism then sends fertilizers into the corresponding holes. The opening and closing of the material bin of the fertilizer distribution mechanism are controlled by its own position. That is, when the fertilizer distribution mechanism moves to a position where the traction assembly is in a tensioned state, as the fertilizer distribution mechanism continues to rotate, the material bin is fully opened, realizing the automatic falling of fertilizers. The fertilization mechanism is set up to achieve linkage with the fertilizer distribution mechanism. When the fertilizer distribution mechanism can push the control end of the fertilization mechanism to rotate, the discharge port of the fertilization mechanism is fully opened. At this time, the feed port of the fertilizer distribution mechanism is aligned with the discharge port of the fertilization mechanism, and the fertilizers in the fertilization mechanism will fall into the fertilizer distribution mechanism, realizing continuous feeding and continuous fertilization, improving the degree of automation, and thus improving production efficiency. The present utility model improves the fertilization efficiency by the method of punching holes first with the hole punching cone and then fertilizing the holes with the fertilizer distribution mechanism.

[0040] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the drawings.

[0041] Please refer to Figures 1 - 6 , a ring-hole fertilizer application device, comprising a housing, a traction assembly 1, a hole punching cone 2, a fertilizer spreading mechanism 3 and a fertilizer application mechanism 4; the fertilizer spreading mechanism 3 and the hole punching cone 2 are connected by a connecting rod 5, and the axial direction of the hole punching cone 2 is perpendicular to the axial direction of the connecting rod 5, so that the fertilizer spreading mechanism 3 and the hole punching cone 2 can synchronously perform circular motion; when the fertilizer spreading mechanism 3 pushes the control end of the fertilizer application mechanism 4 to rotate, the discharge port of the fertilizer application mechanism 4 is opened, and the feed port of the fertilizer spreading mechanism 3 is oppositely arranged with the discharge port of the fertilizer application mechanism 4; the fertilizer spreading mechanism 3 has a main body 31 and a door assembly 32, and the door assembly 32 is slidably connected to the main body 31 to form a bin 33 for accommodating fertilizer 7; one end of the traction assembly 1 is connected to the door assembly 32, and the other end of the traction assembly 1 is connected to the housing. When the traction assembly 1 is in a tensioned state, the bin 33 is opened. Specifically, the hole punching cone 2, the fertilizer spreading mechanism 3 and the fertilizer application mechanism 4 are respectively connected to the housing, and wheels are installed outside the housing to stably control the hole punching position of the hole punching cone 2.

[0042] It is understood that by providing the fertilizer spreading mechanism 3 and the acupuncture cone 2, the fertilizer spreading mechanism 3 and the acupuncture cone 2 are caused to perform circular motion and advance synchronously. The acupuncture cone 2 first acupunctures the fertilizer 7, and then the fertilizer spreading mechanism 3 delivers the fertilizer 7 into the corresponding hole. The opening and closing of the hopper 33 of the fertilizer spreading mechanism 3 is controlled by its own position. That is, when the fertilizer spreading mechanism 3 moves to a position where the traction assembly 1 is in a tensioned state, the hopper 33 is fully opened as the fertilizer spreading mechanism 3 continues to rotate, achieving the automatic drop of the fertilizer 7. The fertilizing mechanism 4 is provided to achieve linkage with the fertilizer spreading mechanism 3. When the fertilizer spreading mechanism 3 is able to drive the control end of the fertilizing mechanism 4 to rotate, the discharge port of the fertilizing mechanism 4 is fully opened. At this time, the feed port of the fertilizer spreading mechanism 3 is aligned with the discharge port of the fertilizing mechanism 4, and the fertilizer 7 in the fertilizing mechanism 4 will fall into the fertilizer spreading mechanism 3, achieving continuous feeding and continuous fertilization, improving the degree of automation, and thereby improving production efficiency. The utility model improves the fertilization efficiency by using the fertilizer spreading mechanism 3 to fertilize the holes after the hole-drilling cone 2 drills the holes first.

[0043] Specifically, the fertilizer distribution mechanism 3 and the acupuncture cone 2 are respectively arranged at the two ends of the connecting rod 5, and the axial direction of the fertilizer distribution mechanism 3 and the axial direction of the acupuncture cone 2 are perpendicular to the axial direction of the connecting rod 5. The setting of the connecting rod 5 is used to make the fertilizer distribution mechanism 3 and the acupuncture cone 2 move synchronously on the one hand, and to keep the acupuncture distance of the acupuncture cone 2 relatively stable on the other hand.

[0044] In some embodiments, a drive mechanism 6 is further included; the drive mechanism 6 includes a drive motor 61, a sprocket assembly 62, a first chain 63, a second chain 64, a first transmission assembly 65 and a second transmission assembly 66 that operate synchronously; the first transmission assembly 65 is transmission-connected to the fertilizer distribution mechanism 3, and the second transmission assembly is transmission-connected to the acupuncture cone 2. The first transmission assembly 65 is used to drive the fertilizer distribution mechanism 3 to perform circular motion, and the second transmission assembly 66 is used to drive the acupuncture cone 2 to perform circular motion. The drive motor 61 is transmission-connected to the sprocket assembly 62, and the sprocket assembly 62 is transmission-connected to the second transmission assembly 66 via the first chain 63. The second transmission assembly 66 is transmission-connected to the first transmission assembly 65 via the second chain 64, so that the first transmission assembly 65 and the second transmission assembly 66 can maintain synchronous circular motion, thereby driving the acupuncture cone 2 and the fertilizer distribution mechanism 3 to perform synchronous circular motion, thereby achieving acupuncture first and then fertilizing, and the two steps are performed simultaneously in different holes, thereby improving fertilization efficiency. Specifically, the first transmission assembly 65 includes a counterweight rotating rod 651, a fixed rotating disk 652, a rotating shaft 653 and a transmission sprocket. The fixed rotating disk 652 is connected to the inner wall of the shell. The counterweight rotating rod 651 is connected to the fixed rotating disk 652 through the rotating shaft 653 so as to be relatively rotatable. The transmission sprocket is sleeved outside the rotating shaft 653 and is transmission-connected to the rotating shaft 653. The second chain 64 is engaged with the transmission sprocket. The structure of the first transmission assembly 65 is the same as that of the second transmission assembly 66, which will not be repeated here.

[0045] In some embodiments, the bin door assembly 32 includes a pressure rod 321, a spring 322, and a blocking member 323 disposed around the main body 31; the traction assembly 1 is connected to the first control end 3211 of the pressure rod 321; the pressure rod 321 is slidably connected to the main body 31, and the spring 322 is sleeved outside the pressure rod 321 and axially clamped between the main body 31 and the second control end 3212 of the pressure rod 321; the blocking member 323 and the main body 31 form a bin 33, and the blocking member 323 is drivingly connected to the second control end 3212 of the pressure rod 321. When the spring 322 is compressed, the bin 33 is opened. After the traction assembly 1 drives the blocking member 323 to move through the pressure rod 321 to open the bin 33, the fertilizer 7 can automatically fall to complete fertilization. With the drive of the first transmission assembly 65, the fertilizer distribution mechanism 3 continuously makes a circular motion, and the tension state of the traction assembly 1 is gradually converted to a relaxed state. Under the push of the spring 322, due to the gradually decreasing traction force of the traction assembly 1, the pressure rod 321 drives the blocking member 323 to reset, and the bin 33 is in a closed state again. At this time, when the feed inlet of the fertilizer distribution mechanism 3 moves to a position directly opposite to the discharge outlet of the fertilization mechanism 4 again, it can receive and store the fertilizer 7 again until the fertilizer distribution mechanism 3 moves to a specified position and then opens the bin 33 for fertilization again. The setting of the above structure can realize automatic fertilization and improve the fertilization efficiency.

[0046] In some embodiments, the main body 31 includes a feed hopper 311 and a blanking chamber 312 arranged in sequence along the axial direction; the feed hopper 311 is communicated with the blanking chamber 312, and the blocking member 323 covers the outside of the blanking chamber 312 to form a bin 33, so that the fertilizer 7 can enter the blanking chamber 312 from the feed hopper 311 for storage to realize automatic fertilization in subsequent steps.

[0047] In some embodiments, the blanking chamber 312 has a guiding inclined surface 3121 that gradually sinks in the direction away from the feed hopper 311. Optionally, there are two guiding inclined surfaces 3121, and the two guiding inclined surfaces 312 are symmetrically arranged to form a triangular prism structure, or the guiding inclined surface 3121 is arranged on a cone. The setting of the guiding inclined surface 3121 can improve the blanking speed of the fertilizer 7 and thus improve the fertilization efficiency.

[0048] In some embodiments, the traction assembly 1 includes a support column 11 and a traction rope 12; the support column 11 is connected to the housing, one end of the traction rope 12 is connected to the support column 11, and the other end is drivingly connected to the pressure rod 321 of the bin door assembly 32. The tension state of the traction rope 12 will continuously change during the circular motion of the fertilizer distribution mechanism 3. Therefore, through the setting of the traction rope 12, the bin door assembly 32 can be accurately controlled to open at the position where fertilization is required and automatically close after fertilization is completed, improving the control accuracy.

[0049] In some embodiments, the fertilizer application mechanism 4 includes a storage hopper 41, a discharge device 42, a partition member 43, and a toothed member 44; the storage hopper 41 is communicated with the discharge device 42, the partition member 43 is installed in the discharge device 42 and forms at least four discharge grooves 421 that are evenly distributed along the circumference of the toothed member 44; the toothed member 44 is in transmission connection with the partition member 43, and the toothed member 44 is arranged outside the discharge device 42. The storage hopper 41 is used to store a large amount of waste materials. The partition member 43 is provided to divide the inner cavity of the discharge device 42 into four discharge grooves 421. During the rotation of the partition member 43, each discharge groove 421 can be aligned with the feed port of the discharge device 42, so that the fertilizer 7 can fall into the corresponding discharge groove 421 for storage. When the discharge groove 421 rotates to a position aligned with the feed hopper 311, the fertilizer 7 can be poured into the feed hopper 311 for the next fertilization. The toothed member 44 is provided for transmission between the fertilizer distribution mechanism 3 and the partition member 43, so that the partition member 43 can rotate after the fertilizer distribution mechanism 3 moves into place, enabling the fertilizer 7 to be accurately transferred and continuous fertilization to be achieved. Specifically, the storage hopper 41 is communicated with the discharge device 42 through a feed pipe.

[0050] In some embodiments, a pushing member 34 is provided at the feed end of the fertilizer distribution mechanism 3. The pushing member 34 can be abutted against the toothed member 44 and push the toothed member 44 to rotate. The pushing member 34 is provided to cooperate with the toothed member 44 to push the partition member 43 to rotate, so that the partition member 43 can sense the position of the fertilizer distribution mechanism 3 and quickly transfer the fertilizer 7. Specifically, the pushing member 34 is arranged on the side of the fertilizer distribution mechanism 3 close to the hole punching cone 2, and the end of the pushing member 34 away from the material bin 33 protrudes outside the top of the feed hopper 311 to prevent interference between the feed hopper 311 and the toothed member 44.
