Description

Technical Field

[0001] The invention relates to the technical field of rice fertilization, in particular to a rice side deep fertilizer applicator. Background Art

[0002] my country is a major agricultural country. For the people of my country, especially in the southern region, rice plays a very important role in their daily lives and is an indispensable food crop. Studies have shown that among the various types of food currently grown in my country, the rice planting area and proportion have reached 30 million hectares and about 25% respectively. Globally, my country has the largest rice planting area. To ensure the quality of rice, fertilization must be done well when planting rice. As we all know, fertilization involves many steps, and 70% of the fertilizer required for rice growth is obtained from the base fertilizer and tillering fertilizer stages.

[0003] For farmers whose primary means of livelihood is crop cultivation, increasing crop yields will also increase their income. Fertilization is essential for ensuring quality during crop production. Research has shown that although my country is a major agricultural country, its per capita arable area is limited due to factors such as its large population. Initially, to increase crop yields, ensure food security, and meet people's food consumption needs, my country used a large amount of chemical fertilizers, which not only affected fertilizer utilization rates but also damaged farmland soil and the ecological environment to a certain extent.

[0004] Deep lateral fertilization involves precisely applying fertilizer 3 to 5 cm to the side of the rice seedlings at a depth of 5 cm during rice cultivation. This allows the fertilizer to reach the rice root system, where it slowly decomposes according to the rice's nutrient needs and is absorbed at different growth stages. Existing methods require deep lateral fertilization machines to apply fertilizer to the rice roots. However, these machines cannot guarantee uniform fertilization, resulting in overfertilization in some areas and underfertilization in others. Furthermore, fertilizer transportation within the machine is prone to blockage. Summary of the Invention

[0005] The object of the present invention is to provide a rice side deep fertilizer applicator capable of achieving uniform fertilization.

[0006] In order to solve the above technical problems, the technical solution of a rice side deep fertilizer applicator in the present invention is as follows:

[0007] A rice side-deep fertilizer spreader includes a plurality of disc fertilizer spreaders arranged in sequence along the left-right direction, each disc fertilizer spreader includes a fertilizer spreader housing, a fertilizer spreader disc with a rotation axis extending in the up-down direction is provided in the fertilizer spreader housing, a plurality of fertilizer spreader grooves are arranged at intervals along the circumference of the fertilizer spreader disc, and the bottom of the fertilizer spreader groove is a fertilizer spreader inclined surface with a height gradually decreasing from the inside to the outside along the radial direction of the fertilizer spreader disc. The fertilizer spreader housing has a first arc segment and a second arc segment formed on the outer circumference of the fertilizer spreader disc, the inner diameter of the second arc segment is adapted to the outer diameter of the fertilizer spreader disc, and the first arc segment corresponds to at least one fertilizer spreader groove. The inner diameter of the first arc segment is larger than the inner diameter of the second arc segment, so that the fertilizer in the fertilizer discharge trough corresponding to the first arc segment enters the first arc segment. The bottom of the fertilizer device shell has a fertilizer discharge port communicating with the first arc segment. The upper end of the fertilizer device shell is provided with a fertilizer device feed port for communicating with the corresponding fertilizer discharge trough. The rice side deep fertilizer spreader also includes a fertilizer feeding mechanism for introducing fertilizer into each fertilizer device feed port. A disc transmission shaft extending from the upper end of the fertilizer device shell is fixed to the middle of each fertilizer discharge disc. The rice side deep fertilizer spreader also includes a disc fertilizer device drive mechanism connected to the transmission shaft of each disc.

[0008] Furthermore, the disc fertilizer dispenser drive mechanism includes a first motor, the motor shaft of the first motor is connected to a horizontal transmission shaft whose rotation axis extends in the left and right directions, the horizontal transmission shaft is connected to a reversing transmission corresponding to the number of fertilizer discharge discs, and the power output end of each reversing transmission is respectively connected to the upper end of the corresponding disc transmission shaft.

[0009] Furthermore, the bottom of the fertilizer discharger shell has a conical hopper that is larger at the top and smaller at the bottom. The fertilizer discharge port is located at the bottom of the conical hopper, and the fertilizer discharge disc is located at the upper hopper port of the conical hopper. The diameter of the upper hopper port of the conical hopper is larger than the outer diameter of the fertilizer discharge disc.

[0010] Furthermore, the fertilizer dispenser housing includes an upper housing and a lower housing fixed together by bolts, the first arc segment and the second arc segment are arranged on the upper housing, and the conical hopper is arranged on the lower housing.

[0011] Furthermore, the fertilizer delivery mechanism includes a spiral fertilizer dispenser respectively arranged on the upper side of each disc fertilizer dispenser, the spiral fertilizer dispenser includes a cylindrical shell with an axis extending in the left and right directions, the cylindrical shell is provided with a spiral conveying dragon with a rotating axis extending in the left and right directions, a fertilizer box is provided at the top of one end of the cylindrical shell, and a spiral fertilizer dispenser fertilizer outlet is provided at the bottom of the other end of the cylindrical shell, and the spiral fertilizer dispenser fertilizer outlet is connected to the corresponding fertilizer dispenser feed port through a fertilizer conveying hose.

[0012] Furthermore, the feed port of the fertilizer discharger is an arc-shaped port, and the outlet of the fertilizer delivery hose is connected to an arc-shaped tube corresponding to the arc-shaped port through a flaring structure.

[0013] Furthermore, the spiral conveying dragon includes a dragon shaft whose axis extends in the left and right directions, and a conveying blade is fixed on the dragon shaft. The dragon shaft is an optical axis structure just above the lower fertilizer outlet of the spiral fertilizer dispenser, and one end of the conveying blade extends to the lower side of the fertilizer outlet of the fertilizer box.

[0014] Furthermore, the rice side deep fertilizer spreader also includes a second motor. The spiral fertilizer dispensers are divided into two groups, and the two groups of spiral fertilizer dispensers are distributed on the left and right sides of the second motor. In the same group of spiral fertilizer dispensers, the spiral conveying dragons of two adjacent spiral fertilizer dispensers are connected by a connecting shaft, and the power output end of the second motor is connected to the spiral conveying dragon close to the second motor in the two groups of spiral fertilizer dispensers.

[0015] The beneficial effects of the present invention are as follows: when the rice side deep fertilizer applicator of the present invention is in use, the fertilizer delivery mechanism delivers fertilizer into the fertilizer feed port, and during the rotation of the fertilizer disc, the fertilizer discharge trough passing through the fertilizer feed port will be filled with fertilizer. As the fertilizer disc rotates, the fertilizer in the fertilizer discharge trough corresponding to the first arc segment enters the first arc segment under the combined action of centrifugal force and gravity, and then passes through the fertilizer discharge port to the fertilization position of the rice. The number of fertilizer discharge troughs corresponding to the first arc segment is fixed, so the amount of fertilizer applied at each fertilization position is also fixed, thereby achieving uniform and continuous rice side deep fertilization.

[0016] Furthermore, fertilizer in the fertilizer box is transported to the optical axis structure via the corresponding spiral conveyor. The fertilizer then falls by its own gravity to the lower fertilizer inlet of the spiral fertilizer dispenser and is then transported to the disc fertilizer dispenser through the fertilizer conveyor hose. The spiral conveyor ensures forced and uniform fertilizer delivery, preventing fertilizer from clogging at the inlet of the disc fertilizer dispenser. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0030] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0031] An embodiment of a rice side deep fertilizer distributor in the application is shown in Figures 1 to 10 : including a frame 1, the frame is provided with a plurality of disc fertilizer distributors 2 arranged in sequence along the left and right directions, the plurality refers to three or more, in this embodiment, the number of disc fertilizer distributors is six.

[0032] Each disc fertilizer distributor 2 comprises a fertilizer distributor housing, a fertilizer disc 20 with a rotation axis extending in the up-down direction is arranged in the fertilizer distributor housing, the fertilizer disc 20 has a plurality of fertilizer grooves 22 arranged uniformly in the circumferential direction on the outer periphery, the upper end of the fertilizer groove 22 extends to the upper end surface of the fertilizer disc, the outer side of the fertilizer groove extends to the outer peripheral surface of the fertilizer disc, and the bottom of the fertilizer groove is a fertilizer slope 19 with a gradually decreasing height from the inside to the outside in the radial direction of the fertilizer disc.

[0033] The fertilizer distributor housing has a first arc segment 24 and a second arc segment 25 formed on the outer periphery of the fertilizer disc, the circumferential length of the second arc segment 25 is longer than that of the first arc segment, the inner diameter of the second arc segment 25 is matched with the outer diameter of the fertilizer disc, so that the fertilizer in the fertilizer groove cannot be discharged at the position corresponding to the second arc segment, and the first arc segment 24 corresponds to at least one fertilizer groove. In this embodiment, the first arc segment can correspond to three fertilizer grooves at the same time. The inner diameter of the first arc segment is larger than that of the second arc segment, so that the fertilizer in the fertilizer groove corresponding to the first arc segment enters the first arc segment. The bottom of the fertilizer distributor housing has a fertilizer discharge port 16 communicating with the first arc segment, and the upper end of the fertilizer distributor housing is provided with a fertilizer distributor feeding port 15 for communicating with the corresponding fertilizer groove. The rice side deep fertilizer applicator further comprises a fertilizer feeding mechanism for feeding fertilizer into each fertilizer distributor feeding port 15, and the middle part of each fertilizer disc is fixed with a disc transmission shaft 18 which is penetrated by the upper end of the fertilizer distributor housing. The rice side deep fertilizer applicator further comprises a disc fertilizer distributor driving mechanism in transmission connection with each disc transmission shaft 18.

[0034] The bottom of the fertilizer distributor housing has a conical hopper 27 with a large upper end and a small lower end, the fertilizer discharge port 16 is located at the bottom of the conical hopper 27, the fertilizer disc is located at the upper end hopper port of the conical hopper, and the diameter of the upper end hopper port of the conical hopper 27 is larger than the outer diameter of the fertilizer disc. In use, when the fertilizer groove carrying the fertilizer rotates to the position corresponding to the first arc segment, under the joint action of centrifugal force and gravity, the fertilizer in the fertilizer groove is thrown and slides to the first arc segment, and then falls into the conical hopper, and then is discharged to the root of the rice through the fertilizer discharge port.

[0035] In this embodiment, the fertilizer distributor housing comprises an upper housing 13 and a lower housing 14 which are fixed together by bolts, the first arc segment 24 and the second arc segment 25 are arranged on the upper housing 13, and the conical hopper 27 is arranged on the lower housing 14. The upper housing and the lower housing are fixed to the rack.

[0036] The driving mechanism of the disc fertilizer distributor comprises a first motor 3 vertically arranged, a horizontal transmission shaft 8 with a rotating axis extending in the left-right direction being drivingly connected to the motor shaft of the first motor, a reversing transmission 9 corresponding to the number of the disc fertilizer distributors being drivingly connected to the horizontal transmission shaft 8, and the power output ends of the reversing transmissions 9 being respectively drivingly connected to the upper ends of the disc transmission shafts 18. The reversing transmission is a gear box with a vertically arranged input section and an output section, the input section being drivingly connected to the horizontal transmission shaft, and the output section being drivingly connected to the disc transmission shaft. The shell of the reversing transmission is fixed to the frame.

[0037] The fertilizer feeding mechanism comprises a spiral fertilizer distributor 2 arranged on the upper side of each disc fertilizer distributor, the spiral fertilizer distributor comprising a cylindrical shell with an axis extending in the left-right direction, the cylindrical shell being provided with a spiral conveying worm with a rotating axis extending in the left-right direction, the top of one end of the cylindrical shell being provided with a spiral fertilizer distributor fertilizer inlet 11, the upper side of the spiral fertilizer distributor fertilizer inlet being provided with a fertilizer box 5, the bottom of the other end of the cylindrical shell being provided with a spiral fertilizer distributor fertilizer outlet 12, and the spiral fertilizer distributor fertilizer outlet being connected to the corresponding fertilizer distributor feeding port through a fertilizer conveying hose.

[0041] When in use, the second motor can drive the spiral conveying dragon of each spiral fertilizer dispenser to rotate, thereby forcibly conveying the fertilizer in the corresponding fertilizer box to the corresponding fertilizer outlet of the spiral fertilizer dispenser, which can avoid the problem of blockage during the discharge process of the fertilizer box. The first motor drives the horizontal transmission shaft to rotate, thereby driving the disc transmission shaft to rotate. When the fertilizer trough rotates to the position of the fertilizer dispenser feed port, the fertilizer falls into the fertilizer trough from top to bottom. As the fertilizer trough continues to rotate, when the fertilizer trough rotates to the corresponding position of the first arc segment, under the combined action of centrifugal force and gravity, the fertilizer passes through the fertilizer trough to the first arc segment, and then through the conical hopper and the fertilizer outlet to the roots of the rice, realizing continuous and uniform side deep fertilization of rice.
