Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a fertilizing device for bagged slow-release fertilizers. Background Art

[0002] China is a large agricultural country. In 2014, my country used 59.9594 million tons of fertilizers for agricultural production, ranking first in the world. Fertilizers are the basic material to ensure agricultural production. More than half of the increase in grain production is attributed to the use of fertilizers. Although my country's fertilizer production and consumption continue to grow, high fertilization levels do not bring high fertilizer utilization rates. Low fertilizer utilization rates not only lead to more fertilizers to meet the needs of crop growth, which is labor-consuming and time-consuming, but also fertilizers that are not absorbed by crops will accumulate in the root system, causing salt damage, destroying the cell structure of the root system, and ultimately leading to a decrease in crop yields or even death. At the same time, the soil structure is destroyed, and problems such as surface eutrophication and excessive nitrate nitrogen content in groundwater occur, causing environmental pollution.

[0003] At present, my country's fruit trees, vegetables, cotton, tea, grapes and other economic crops generally have serious fertilizer loss, low utilization rate, unbalanced and unstable nutrient supply during the production process, and problems such as soil compaction and environmental pollution caused by large-scale indiscriminate fertilization and excessive fertilization. Double-film controlled-release fertilizer can effectively solve the above problems, greatly improve fertilizer utilization rate, reduce fertilizer loss and the resulting environmental pollution, improve geographical conditions and fertilization environment, and greatly reduce farmers' fertilizer input and labor intensity. Double-film controlled-release fertilizer adjusts the release rate of quick-acting nutrients inside fertilizer particles through an organic coating layer. Therefore, the fertilization of dual-mode controlled-release fertilizer mainly acts on various fruit trees and requires continuous and uniform application. In order to achieve the continuous and orderly delivery of bag fertilizer bags, the present invention designs a bagged slow-release fertilizer orderly fertilization device.

[0004] Slow-release fertilizer is a new type of fertilizer. It can adjust the release rate of quick-acting nutrients inside fertilizer particles through an organic coating layer, so that the release of nutrients in fertilizer is basically synchronized with the nutrient demand of crops. It only needs to apply base fertilizer once at the beginning of the entire growth stage of crops to meet the fertilizer needs of crops, and can effectively prevent soil compaction. It has advantages that ordinary chemical fertilizers cannot match in terms of improving fertilizer nutrient utilization, increasing agricultural production and income, and reducing resource waste and environmental pollution. The successful development and promotion of slow-release fertilizers have achieved certain economic and ecological benefits in developed countries. Therefore, many agricultural scientists believe that slow-release fertilizers will be an important development direction of the fertilizer industry in the 21st century.

[0005] Chinese patent document CN107827566A, application publication date 2018-03-23, discloses a "bagged slow-release fertilizer and application method". The technology discloses a bagged slow-release fertilizer, including a degradable bag body, which is made of degradable plastic, non-woven fabric or kraft paper, has multiple through holes, and is applied together with the bag body when in use.

[0006] Chinese patent document CN103011987A, application publication date 2013-04-03, records a double-film dual-controlled slow-release fertilizer, which is made by wrapping urea with sulfur and then wrapping it with a layer of soluble resin. It is a mixture of urea with double-layer film material and stable compound fertilizer. It generally has the effect of one-time fertilization without topdressing, and is applied together with the bag when used.

[0007] The fertilization device (also known as a fertilizer dispenser) is a key component of the fertilizer application machine. Its working performance directly affects the quality of fertilization and is related to the distribution of fertilizers in the soil. Slow-release fertilizers are packaged in degradable paper. The paper bags have a large friction coefficient and are difficult to separate in the fertilizer box. In order to improve the utilization of fertilizers by fruit trees in the forest, fertilization is mostly concentrated next to fruit trees and other crops to continuously and evenly apply a certain amount. At present, there is no ideal fertilization device (fertilizer dispenser) for deep application of bagged slow-release fertilizers. Orderly separation and application have become the bottleneck problem of deep application machines for bagged fertilizers. Therefore, it is necessary to study the orderly discharge of bagged slow-release fertilizers.

[0008] Further searching revealed that Chinese patent document CN108521913A, with an application publication date of 2018-09-14, records an automatic fertilization device for agricultural machinery. This technology can realize automatic fertilization and achieve accurate concentration ratio and uniform fertilization of fertilizers in the agricultural fertilization process, but there is no way to achieve reasonable and orderly release of bagged slow-release fertilizers.

[0009] Chinese patent document CN108174669A, application publication date 2018-06-19, records a layered fertilization device. This technology can realize a layered and multi-dimensional fertilization method to improve the utilization rate of fertilizers, but it also has no way to achieve reasonable and orderly application of bagged slow-release fertilizers.

DETAILED DESCRIPTION

[0032] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detailed manner in conjunction with the accompanying drawings and preferred embodiments below, but the protection scope of the present invention is not limited to the following specific embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0033] Unless otherwise defined, all technical terms used hereinafter have the same meaning as those generally understood by those skilled in the art. The words "first", "second" and similar words used in the patent application specification and claims of the present invention do not indicate any order, quantity or importance, but are merely for the convenience of distinguishing the corresponding parts. Similarly, words such as "one" or "an" do not indicate a quantity limitation, but indicate the existence of at least one. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0034] The A direction marked in the accompanying drawings of the present invention (see Figure 1 and Figure 3 ) is the forward direction of the fertilizing device. The "front side" or "front" mentioned below is the same as the forward direction A, and the "rear side" or "rear" is opposite to the forward direction A.

[0035] See also Figures 1 to 8 A fertilizing device for bagged slow-release fertilizer according to an embodiment of the present invention mainly comprises a fertilizer box 10, a vibrating dredging device 11, a stirring device 12, an orderly feeding device 15 and a fertilizer discharging mechanism 16. The fertilizer box 10 is a hollow structure, and the fertilizer bag 100 (see Fig. 9 ) is put into the fertilizer bag from the fertilizer bag feed port 101 of the fertilizer box 10. A vibration dredging device 11 is provided at the bottom of the fertilizer box 10 to drive the vibration plate 115 to vibrate, so that the fertilizer bag 100 slides along the dredging surface 116 toward the fertilizer box outlet channel 14 under the action of vibration. Two stirring rods, an inner stirring rod 121 and an outer stirring rod 122, are provided in front of the upper part of the fertilizer box outlet channel 14. With the assistance of their rotation, the fertilizer bag 100 is easier to fall into the fertilizer box outlet channel 14. An orderly feeding device 15 is provided below the fertilizer box outlet channel 14, and is used to drop the fertilizer bags 100 in the fertilizer box outlet channel 14 onto the fertilizer discharge mechanism 16 in an orderly manner at intervals. The fertilizer discharge mechanism 16 is provided below the orderly feeding device 15, and is used to transport the fertilizer bags 100 dropped from the orderly feeding device 15 to the fertilization point.

[0036] When the above-mentioned bagged slow-release fertilizer fertilizing device is used, a certain number of fertilizer bags 100 of bagged slow-release fertilizer are put into the fertilizer box from the fertilizer bag feed port 101, and the fertilizer bags 100 slide down the inclined surface 116 on the vibration plate 115 under the vibration of the vibration plate 115, and then the fertilizer bags 100 are guided and separated under the action of the two inner stirring rods 121 and the outer stirring rod 122, so that the fertilizer bags 100 can reliably fall into the fertilizer box outlet channel 14, and fall from the fertilizer box outlet channel 14 to the orderly feeding device 15, and the fertilizer bags 100 are then separated and orderly fallen on the fertilizer discharge mechanism 16 from the bottom of the orderly feeding device 15, and the fertilizer discharge mechanism 16 then transports the orderly fertilizer bags 100 to the fertilization point, so as to realize the orderly discharge of the bagged slow-release fertilizer.

[0037] Specifically, see Figure 2 , Figure 3 , Figure 5 In this embodiment, the vibration drainage device 11 is provided with a vibration plate 115, and the vibration plate 115 is installed at the lower part of the fertilizer box 10. The vibration plate 115 is provided with an inclined drainage surface 116. The vibration plate 115 is hinged to the fertilizer box 10 through a hinge bolt 114, and the vibration plate 115 can rotate with the hinge point as the axis. The drainage surface 116 on the vibration plate 115 and the inner wall of the fertilizer box 10 form a closed cavity space. The drainage surface 116 on the vibration plate 115 is higher on the fertilizer bag feed port 101 side and lower at the hinge bolt 114. The vibration drainage device 11 is also provided with a vibration fixed bracket 111, and the vibration fixed bracket 111 is rigidly connected to the fertilizer box 10. A groove for placing an eccentric wheel 112 is provided in the middle of the fixed bracket 111. The eccentric wheel 112 is installed in the middle of the groove of the fixed bracket 111, and the upper end surface of the eccentric wheel 112 always keeps in contact with the vibration plate 115. The guide spring 113 is located on both sides of the eccentric wheel 112, one end of the guide spring 113 is fixed to the bottom of the vibration plate 115, and the other end is fixed to the vibration fixing bracket 111, which more reliably ensures that the end face of the eccentric wheel 112 and the bottom of the vibration plate 115 are continuously and closely fitted. When power is input to the eccentric wheel 112 to make it rotate, the vibration plate 115 closely fitted to the eccentric wheel 112 will perform continuous pendulum vibration, and work together with the inclined dredging surface 116 to move the fertilizer bag 100 dropped from the fertilizer bag feed port 101 to the other side of the fertilizer box 10.

[0038] In order to better transport a large number of fertilizer bags 100 to the fertilizer box outlet channel 14, that is, to guide and disperse the fertilizer bags 100 sliding down along the vibrating guiding device 11, refer to Figure 3 , Figure 4 and Figure 8A stirring device 12 is arranged behind the vibration drainage device 11 and near the top of the fertilizer box outlet channel 14. The stirring device 12 includes an inner stirring rod 121 and an outer stirring rod 122. The inner stirring rod 121 and the outer stirring rod 122 are mounted on a stirring rod bracket 125. A stirring rod motion reversing device 124 is arranged on the stirring device 12. When power is input from the stirring device power input shaft 123, the inner stirring rod 121 and the outer stirring rod 122 rotate in opposite directions. Spherical stirring rod shifting heads 126 are arranged at the shifting rod ends of the inner stirring rod 121 and the outer stirring rod 122. This design is to prevent damage to the bag body of the fertilizer bag 100 during the stirring process. Figure 8 As shown, the stirring rod motion reversing device 124 comprises an intermediate bevel gear 1242 mounted on the stirring rod bracket 125; an inner stirring rod bevel gear 1241 mounted at the end of the inner stirring rod 121; and an outer stirring rod bevel gear 1243 mounted at the end of the outer stirring rod 122. The inner stirring rod bevel gear 1241 and the outer stirring rod bevel gear 1243 are respectively meshed with the intermediate bevel gear 1242. When power is input from the stirring device power input shaft 123, due to the operation of the stirring rod motion reversing device 124, the inner stirring rod 121 and the outer stirring rod 122 rotate in opposite directions, so that the rotating rod moves the fertilizer bag 100, so that it is effectively dispersed and guided, and accurately slides into the entrance of the fertilizer box outlet channel 14. As described above, only one driving force is needed to make the two stirring rods rotate and move in opposite directions. Under the stirring of the inner stirring rod 121 and the outer stirring rod 122, it is possible to prevent a plurality of fertilizer bags 100 from being piled up and blocked above the fertilizer box outlet passage 14 and the fertilizer bags 100 from being stuck in an incorrect posture on the fertilizer box outlet passage 14. The ends of the stirring rods are in the shape of a ball (see Figure 8 ), the advantage of this is that the stress of the stirring rod contacting the fertilizer bag 100 can be reduced, thereby preventing the stirring rod from damaging the fertilizer bag 100.

[0039] See also Figure 3 , Figure 4 , Figure 6 and Figure 7 In the embodiment, a fertilizer box outlet passage 14 is fixed below the fertilizer box 10 (see Figure 7), the upper part of the fertilizer box outlet channel 14 is rigidly connected to the fertilizer box 10, and the lower part has an inner concave arc surface that fits and connects with the outer circular surface of the orderly feeding device 15. A fertilizer bag diverter plate 141 and two bag drop gap control plates 142 are provided inside the fertilizer box outlet channel 14. The fertilizer bag diverter plate 141 and the bag drop gap control plates 142 form four bag drop gaps 143 with the side wall of the fertilizer box outlet channel 14. The bag drop gap 143 space is set to allow no more than one bag of fertilizer 100 to pass through. The fertilizer bag diverter plate 141 and the bag drop gap control plates 142 are provided with an inclined end surface 144 on the upper part. The height of the two bag drop gap control plates 142 is set shorter than the fertilizer bag diverter plate 141, so two main channels are formed at the upper part of the fertilizer box outlet channel 14, and the width of each main channel is slightly larger than the length of the fertilizer bag 100, so that the fertilizer bag 100 can fall down easily. Each main channel is divided into two bag drop gaps 143 by the bag drop gap control plate 142, and the fertilizer bag 100 is separated in order through the diversion of the inclined end surface 144. Each bag drop gap 143 can accommodate multiple bags of fertilizer bags 100 in the vertical direction, and the sharp corners of the bag drop gap control plate 142 and the fertilizer bag diverter plate 141 are processed with arc transition, so that the fertilizer bag 100 is difficult to maintain balance on the sharp corner and fall into the main channel at an angle, and the fertilizer bag 100 will not be damaged.

[0040] For further information, see Figure 3 , Figure 4 and Figure 6 The ordered feeding device 15 comprises an ordered feeding device housing 151 and an ordered feeding rotor 152. The ordered feeding device housing 151 is rigidly connected to the fertilizer box outlet passage 14. The ordered feeding rotor 152 is installed inside the ordered feeding device housing 151. The ordered feeding rotor 152 is rotated by power input from the ordered feeding device power input shaft 153. The ordered feeding rotor 152 has four fertilizer bag storage spaces 154 evenly distributed along the axial direction of the ordered feeding device power input shaft 153, which are used to receive the fertilizer bags 100 dropped from the fertilizer box outlet passage 14. The projections of the fertilizer bag storage spaces 154 on the end plane of the ordered feeding rotor 152 are also evenly distributed in a circle (see Figure 6 ), the fertilizer bag storage space 154 is configured to accommodate at most one bag of fertilizer bags 100, and the number of the four fertilizer bag storage spaces 154 is aligned with the spatial positions of the four bag drop gaps 143. When the orderly feeding rotor 152 rotates, each fertilizer bag storage space 154 is sequentially and orderly aligned with each bag drop gap 143 of the fertilizer box outlet 14, and when the two windows are aligned, the fertilizer bag 100 falls from the bag drop gap 143 into the bag drop gap 143, and finally the fertilizer bags 100 fall from the outlet below the orderly feeding device 15 to the lower conveyor belt 162 in the fertilizer discharge mechanism 16 in an orderly and spaced manner.

[0041] See also Figures 1 to 3In this embodiment, the fertilizing device further includes a support frame 13, the support frame 13 is fixedly mounted on a fertilizing device base 17, the fertilizer box 10 is mounted on the support frame 13, and the fertilizing device base 17 is equipped with wheels 18. A certain gap is left between the support frame 13 and the vibration plate 15, so that the vibration plate 15 will not interfere with the support frame 13 when working.

[0042] See also Figures 1 to 4 In this embodiment, the fertilizer discharging mechanism 16 includes: a lower conveyor belt 162, an upper conveyor belt 161 and a conveyor belt side plate 163. The lower conveyor belt 162 is arranged below the discharge port of the orderly feeding device housing 151, and is used to receive the fertilizer bag 100 dropped from the orderly feeding device housing 151. The upper conveyor belt 161 is arranged above the lower conveyor belt 162, and the gap between the belt of the upper conveyor belt 161 and the belt of the lower conveyor belt 162 is slightly smaller than the thickness of the fertilizer bag 100. The conveyor belt side plate 163 is arranged on the base 17, and the upper conveyor belt 161 and the lower conveyor belt 162 are both fixed between the two conveyor belt side plates 163. In this arrangement, the upper conveyor belt 161 and the lower conveyor belt 162 can form a clamping force on the fertilizer bag 100, so that the clamped fertilizer bag 100 moves to the rear side of the fertilizer discharge mechanism 16 and is thrown out horizontally and orderly from the rear ends of the upper conveyor belt 161 and the lower conveyor belt 162, which is conducive to the bottom surface of the fertilizer bag 100 contacting the soil. The clamping force can also make the thickness of the fertilizer bag 100 uniform.

[0043] The working principle of the fertilization device of the present invention is as follows:

[0044] When in use, a certain number of slow-release fertilizer bags 100 are placed at the fertilizer bag feed port 101 on the fertilizer box 10, and the eccentric wheel 112 of the vibration dredging device 11, the stirring device 12, the orderly feeding device 15 and the driving power 16 of the fertilizer discharge mechanism are started. The vibration plate 115 generates up and down pendulum vibration under the action of the eccentric wheel 112 of the vibration dredging device 11. The vibrated fertilizer bags 100 slide toward the rear of the fertilizer box 10 along the inclined dredging surface 116, and then the fertilizer bags 100 are dredged and dispersed by the two inner stirring rods 121 and the outer stirring rods 122 of the stirring device 12 with different directions, and fall into the fertilizer box outlet channel 14. The orderly separation of the fertilizer bags 100 is achieved through the limitation and diversion of the size of the bag-falling gap space 143 in the fertilizer box outlet channel 14. Under the rotation of the orderly feeding rotor 152, the fertilizer bags 100 in the bag dropping gap 143 slide into the fertilizer bag storage space 154 of the orderly feeding rotor 152. When the fertilizer bag storage space 154 rotates to the lower exit of the orderly feeding device 15, the fertilizer bags 100 fall onto the lower conveyor belt 162 in an orderly and spaced manner. The fertilizer bags 100 move backwards, and after a short distance, the fertilizer bags 100 contact the upper conveyor belt 161. At this time, the fertilizer bags 100 are clamped by the belts of the upper conveyor belt 161 and the lower conveyor belt 162 and move toward the rear end, and are finally thrown out horizontally and orderly from the rear end of the fertilizer discharge mechanism 16.

[0045] The bagged controlled-release fertilizer orderly fertilization device of the present invention can be transformed into a carrier (such as Figures 1 to 4 It can also be installed on other mobile or self-propelled vehicles, or installed on agricultural machinery with a furrow opener in front and a soil covering device in the rear for joint use.

[0046] The vibration frequency and amplitude of the vibration drainage device 11 in the present invention, the size of the fertilizer box outlet channel 14, the bag drop gap 143 and the size of the fertilizer bag storage space 154 can all be determined based on the size parameters of the fertilizer bag 100.

[0047] The feeding components and conveying components of the present invention cause relatively little damage and wear to the fertilizer bag 100, thus ensuring the normal use of the fertilizer bag 100 after it falls on the fertilization point. At the same time, the upper conveyor belt 161, the lower conveyor belt 162 and the driving wheels of the orderly feeding device 15 can be driven independently, and with a suitable control system, the fertilization frequency of the device can be matched with the forward speed of the carrier, so that the spacing of the fertilizer bags 100 applied by the fertilization device is consistent and orderly at different forward speeds of the carrier.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
