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.

When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0036] The A direction marked in the accompanying drawings of the present invention (see Figure 2 ) is the forward direction of the fertilization device, and B direction (see Figure 2 ) is the conveying direction of the vibrating conveyor plate.

[0037] See also Figures 1 to 10 A fertilizing device for bagged slow-release fertilizer according to an embodiment of the present invention mainly comprises a fertilizer box 1, a vibrating conveying plate 2, a vibrating device 10, a feeding device 20, a fertilizer bag passage 205, an orderly feeding device 40, and a clamping device 50. The fertilizer box 1 is a hollow structure with openings at both ends, and the fertilizer bag 8 (see Fig. 9and Fig.10 ) is put in from the upper part of the fertilizer box 1; the vibrating conveying plate 2 is arranged at the bottom of the fertilizer box 1, and the distance between the opening at the bottom of the fertilizer box 1 and the conveying surface of the vibrating conveying plate 2 forms a fertilizer box discharge port 4; the vibrating device 10 is connected to the vibrating conveying plate 2, and the vibrating device 10 is used to drive the fertilizer box 1 and the vibrating conveying plate 2 to vibrate, so that the fertilizer bags 8 inside the fertilizer box 1 are dispersed and changed in posture under the action of vibration, and a part of the fertilizer bags 8 slide out from the fertilizer box discharge port 4 and continue to move along the conveying surface of the vibrating conveying plate 2 toward the B direction (see Figure 2 ) slide; the unloading device 20 is arranged at one end of the vibrating conveying plate 2, and after the fertilizer bags 8 on the vibrating conveying plate 2 fall into the unloading device 20, the unloading device 20 separates the multiple fertilizer bags 8 in sequence; the fertilizer bag channel 205 is vertically arranged below the unloading device 20, and the size of the fertilizer bag channel 205 can only allow one fertilizer bag 8 to pass through; the orderly feeding device 40 is connected to the bottom of the fertilizer bag channel 205, and the fertilizer bags 8 in the fertilizer bag channel 205 fall into the orderly feeding device 40, and then the orderly feeding device 40 fertilizer bags 8 are transported to the fertilization point in an orderly manner; the clamping device 50 is connected to the orderly feeding device 40. When the orderly feeding device 50 is ready to deliver the fertilizer bag 8 to the fertilization point, the clamping device 50 will clamp the fertilizer bag 8 waiting to fall at the bottom of the fertilizer bag channel 205 to prevent the fertilizer bag 8 from falling to the orderly feeding device 40. When the fertilizer bag 8 in the orderly feeding device 40 is transported to the fertilization point, the clamping device 50 will release the fertilizer bag 8 in the fertilizer bag channel 205 and continue to fall to the orderly feeding device 40.

[0038] The above-mentioned bagged slow-release fertilizer fertilizing device is fixed on one end of the vibrating conveying plate 2 through the fertilizer box 1, and a vibrating device 10 is provided to be connected with the vibrating plate conveying plate 2. When in use, a certain number of bagged slow-release fertilizer bags 8 are put into the fertilizer box 1 from above. Under the vibration action of the vibrating device 10, a part of the fertilizer bags 8 at the bottom of the fertilizer box 1 slide out toward the fertilizer box discharge port 4. Under the action of vibration, the fertilizer bags 8 that slide out of the fertilizer box discharge port 4 continue to slide in the conveying direction of the vibrating conveying plate 2, and then the fertilizer bags 8 fall to the unloading device 20. Multiple fertilizer bags 8 are separated in turn in the unloading device 20 and fall into the fertilizer bag channel 205 one by one. The fertilizer bags 8 fall to the orderly feeding device 40 along the fertilizer bag channel 205 in an orderly manner. The orderly feeding device 40 then delivers the fertilizer bags 8 to the fertilization point in an orderly manner, thereby realizing the orderly application of bagged slow-release fertilizer.

[0039] Specifically, see Figure 1 and Figure 2In this embodiment, the conveying surface of the vibrating conveying plate 2 is inclined to the horizontal, which facilitates the sliding of the fertilizer bag 8. The bottom of the fertilizer box 1 is parallel to the conveying surface of the vibrating conveying plate 2 to form a fertilizer box discharge port 4. The size of the fertilizer box discharge port 4 does not allow more than two bags of fertilizer bags 8 to pass through at the same time. A cleaning wheel 3 is provided between the baffles on both sides of the vibrating conveying plate 2. The cleaning wheel 3 rotates and works, and the linear speed direction of its lowermost end face is opposite to the moving direction of the fertilizer bag. It is used to clean the remaining fertilizer bags 8 that are stacked on the conveying surface of the vibrating conveying plate 2. By adopting the above structure, the fertilizer bags 8 at the bottom of the fertilizer box 1 come out from the fertilizer box discharge port 4 under the action of the vibration device 10, and then continue to slide along the conveying surface of the vibrating conveying plate 2. During the sliding process of the vibrating conveying plate 2, if the remaining fertilizer bags 8 are stacked on more than two bags, they will be pushed backward by the cleaning wheel 3, so that no more than two bags of fertilizer bags pass through the lower part of the cleaning wheel 3.

[0040] See also Figure 1 and Figure 2 The fertilizing device also includes a bracket 5, which is fixedly mounted on a base 6, and four wheels 7 are arranged around the base 6. The vibration device 10 specifically includes: four vibration isolation springs 101, two vibration motors 102, and four spring bases 103. Among them, the four spring bases 103 are fixedly mounted around the bottom of the vibration conveying plate 2, one end of the vibration isolation spring 101 is connected to the bracket 5, and the other end of the vibration isolation spring 101 is connected to the spring base 103, and the two vibration motors 102 are fixedly mounted on the bottom of the vibration conveying plate 2. With this arrangement, when the vibration motor 102 is working, the fertilizer box 1 and the vibration conveying plate 2 will vibrate, and under the action of the vibration isolation spring 101, a vibration action is generated to facilitate the separation and sliding of the fertilizer bag 8.

[0041] See also Figure 1 and Figure 2In this embodiment, the unloading device 20 includes: a receiving plate 201, a waiting area 202, a guide wheel 203, and a feeding wheel 204. The receiving plate 201 is tilted downward, and the receiving plate 201 is located below the end of the vibrating conveying plate 2, and is used to receive the fertilizer bags 8 falling from the top of the vibrating conveying plate 2. The waiting area 202 is a semi-enclosed space formed by the receiving plate 201 and the baffles on both sides. The guide wheel 203 is set between the baffles on both sides and is biased towards the top of the waiting area 202. The feeding wheel 204 is set between the baffles on both sides and is biased towards the downward end of the receiving plate 201. The distance between the guide wheel 203 and the feeding wheel 204 is set so that no more than one bag of fertilizer bags 8 can pass through. The linear velocity direction of the side of the dredging wheel 203 in contact with the fertilizer bag is opposite to the moving direction of the fertilizer bag, and the rotation direction of the feeding wheel 204 is opposite to the rotation direction of the dredging wheel 203. With such a configuration, the fertilizer bags 8 in the waiting area 202 can only be transported downward by the feeding wheel 204 at the same time under the dredging action of the dredging wheel 203. Further, the upper end of the fertilizer bag passage 205 is combined with the lower part of the waiting area 202, and the size of the fertilizer bag passage 205 is set to allow only one bag of fertilizer bags 8 to pass through, and multiple bags of fertilizer bags 8 can be accommodated in the vertical direction of the fertilizer bag passage 205. With such a configuration, the fertilizer bags 8 in the waiting area 202 can be vertically dropped into the fertilizer bag passage 205 one by one through the dredging wheel 203 and the feeding wheel 204, and a plurality of fertilizer bags 8 are in an orderly queue state of a single bag in the fertilizer bag passage 205.

[0042] In order to deliver the fertilizer bags 8 to the fertilization point in an orderly manner, see Figures 1 to 10 The orderly feeding device 40 includes: a push block 401, a connecting rod 402, a connecting rod 403, a connecting rod input shaft 404, a connecting rod base 405, a baffle plate 406, and a material drop box 407. The material drop box 407 is fixed on the base 6, and there is a row of fat openings 471 in the middle of the material drop box 407 (see Figure 7 ), the opening above the fertilizer discharge port 471 is connected to the fertilizer bag channel 205, and the size of the fertilizer discharge port 471 is set to only allow one bag of fertilizer 8 to be accommodated, and a transverse groove 472 is opened on each side of the drop box 407. The connecting rod base 405 is fixed on the base 6. The connecting rod input shaft 404 is rotatably mounted on the connecting rod base 405. One end of the connecting rod 403 is connected to the connecting rod input shaft 404, and when the connecting rod input shaft 404 rotates, it will drive the connecting rod 403 to rotate. The push block 401 is installed at one end of the fertilizer discharge port 471, and the height of the push block 401 is slightly larger than the length of half a bag of fertilizer 8; a hinge bolt 408 is provided on one side of the push block 401 (see Figure 5 ), the hinge bolt 408 is guided by the transverse groove 472 on one side of the blanking box 407, and the pusher block 401 can only move horizontally in the slide groove in the middle of the blanking box 407; one end of the connecting rod 402 is connected to the hinge bolt 408, and the other end of the connecting rod 402 is connected to the connecting rod 403. Fig. 9 and Fig.10 ), when power is input to the power input shaft 404, the connecting rod 404 rotates through the connecting rod 402 to drive the pushing block 401 to make periodic horizontal movement in the empty slot, pushing the fertilizer bag 8 at the fertilizer discharge port 471 to the fertilization point; when the fertilizer bag 8 at the fertilizer discharge port 471 is pushed to the fertilization point, the fertilizer bag channel 205 will replenish the fertilizer bag 8 to the fertilizer discharge port 471, and finally the above cycle is completed in sequence to achieve orderly release of the fertilizer bags 8.

[0043] Further, see Figure 3 , Figure 6 , Fig. 9 A baffle plate 406 is provided outside the fertilizer discharge port 471, and the baffle plate 406 is connected to the pusher block 401 by a long rod, which is embedded in a transverse groove 472 on one side of the material drop box 407, and the pusher block 401 moves horizontally with the baffle plate 406. In this way, when the pusher block 401 does not push the fertilizer bag 8, the baffle plate 406 blocks the fertilizer discharge port 471 to prevent the fertilizer bag 8 from leaking out.

[0044] See also Figures 4 to 8In order to better push the fertilizer bag 8 by the pushing block 401 and prevent the fertilizer bag 8 in the fertilizer bag channel 205 from falling and blocking the fertilizer discharge port 471 during the pushing process of the fertilizer bag 8 by the pushing block 401, the fertilizing device is further provided with a clamping device 50. The clamping device 50 includes: a clamping plate 501, a clamping connecting rod 502, a supporting seat 503, a clamping driving connecting plate 504, and a clamping driving pulley 505. The upper end of the clamping link 502 is connected to the clamping plate 501, and the lower end of the clamping link 502 is connected to the clamping drive link plate 504. The clamping link 502 is generally kept in a vertical state; the support seat 503 is fixed on one side of the blanking magazine 407, and the middle hinge of the clamping link 502 is connected to the support seat 503; the clamping drive pulley 505 is installed on one side of the pushing block 401, and the clamping drive pulley 505 contacts the guide surface of the clamping drive link plate 504 through the transverse groove 472 on the other side of the blanking magazine 407. In this way, when the pushing block 401 pushes the material, the clamping drive pulley 505 moves forward horizontally in the transverse groove 472 on one side, and then the guide surface of the clamping drive connecting plate 504 is forced to cause the clamping connecting rod 502 to have one end of the clamping drive connecting plate 504 tilt outward with the support seat 503 as the fulcrum, and at the same time, the clamping connecting rod 502 has one end of the clamping plate 501 tilted toward the inside of the fertilizer bag channel 205, and the clamping plate 501 enters the side hole 506 of the fertilizer bag channel to clamp The fertilizer bag 8 at the bottom of the fertilizer bag channel 205 is held to prevent the fertilizer bag 8 from falling into the fertilizer discharge port 471; when the pushing block 401 pushes the fertilizer bag 8 at the fertilizer discharge port 471 to the fertilization point, the pushing block 401 moves back to the initial position, then the clamping device 50 is released, and the clamping plate 501 comes out of the side hole 506 of the fertilizer bag channel, and the fertilizer bag in the fertilizer bag channel 205 continues to fall into the fertilizer discharge port 471, and then the above-mentioned actions of clamping and pushing the fertilizer bag are continuously repeated.

[0045] The working principle of the fertilization device of the present invention is as follows:

[0046] When in use, a certain number of fertilizer bags 8 of bagged slow-release fertilizer are placed in the upper opening of the fertilizer box 1, and the driving force of the vibration motor 102, the cleaning wheel 3, the unloading device 20, and the orderly feeding device 40 are started. With the assistance of four vibration isolation springs 101, the fertilizer box 1 and the vibration conveying plate 2 vibrate; the fertilizer bags 8 in the fertilizer box 1 are spread out and adjusted under the action of vibration, and the fertilizer bags 8 slide out to the fertilizer box discharge port 4 in a lying posture, and continue to slide along the conveying direction B of the vibration conveying plate 2 to the receiving plate 201 of the unloading device 20. During the sliding process, the remaining fertilizer bags 8 stacked on each other for more than two bags will be scraped off by the cleaning wheel 3; the fertilizer bags 8 on the receiving plate 201 are contacted by the dredging wheel 203 and the feeding wheel 204, and the distance between the dredging wheel 203 and the feeding wheel 204 is set The arrangement is to allow no more than one bag of fertilizer 8 to pass through; under the rotation and friction of the guiding wheel 203 and the feeding wheel 204, the fertilizer bags 8 fall into the fertilizer bag channel 205 one by one, and the fertilizer bags 8 are in a vertical posture in the fertilizer bag channel 205, and multiple bags of fertilizer bags 8 are in an orderly queue state in the fertilizer bag channel 205; when a single bag of fertilizer bag 8 falls from the fertilizer bag channel 205 to the fertilizer discharge port 471, the fertilizer bag 8 is pushed forward horizontally by the pushing block 401, and the clamping device 50 is triggered accordingly, and the clamping plate 501 enters from the fertilizer bag side hole 506 to clamp the fertilizer bag 8 at the bottom of the fertilizer bag channel 205, and the fertilizer bag 8 in the fertilizer discharge port 471 is squeezed out of the fertilizer discharge port 471 by the pushing block 401 and falls to the fertilization point, and the base 6 of the orderly feeding device 40 facing the fertilizer discharge port 471 has a notch (see Figure 1 ), the fertilizer bag 8 can fall onto the ground through the gap. After the pushing block 401 completes pushing of fertilizer, the pushing block 401 moves backward horizontally to return to the initial position, and then the clamping device 50 is released, and the fertilizer bags 8 in the fertilizer bag channel 205 continue to fall to the fertilizer discharge port 471 in single packages, and the pushing block 401 continues to push fertilizer, and the above actions are continuously repeated to finally realize the orderly application of the fertilizer bags 8 of the slow-release fertilizer.
