TECHNICAL FIELD

[0001] The present application relates to the technical field of fertilizer release equipment, in particular to a fertilizer release equipment based on precise control and a method thereof. BACKGROUND

[0002] After the fertilizer is produced, it needs to be packaged in a timed and quantitative manner, that is, the packaging bag is conveyed to the lower side of the storage bin in a timed manner, and is packaged into the packaging bag in a quantitative manner. Although the existing fertilizer release equipment can realize the timed and quantitative packaging of the fertilizer, it still has certain deficiencies, that is, the quantitative error is large. The main reason is that even if the weighing device can accurately weigh the weight of the fertilizer, a certain amount of fertilizer will still be in a falling state when the discharge pipe is closed. These fertilizers in the falling process will eventually fall into the packaging bag, resulting in a large quantitative error. In addition, in order to reduce the error caused by this phenomenon, the fertilizer discharge speed and discharge amount are reduced. However, such operation will affect the work efficiency of the packaging. SUMMARY

[0003] The present application relates to the technical field of fertilizer release equipment, in particular to a fertilizer release equipment based on precise control and a method thereof.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: A fertilizer release equipment based on precise control, comprising: a supporting and discharging table, a storage bin is fixedly arranged on the supporting and discharging table, and the storage bin is used for storing fertilizer; A redundant material receiving assembly is installed on the supporting and discharging table, and is used for receiving redundant fertilizer during the falling of the fertilizer; A receiving and closing assembly is installed on the redundant material receiving assembly, and is used for closing the redundant material receiving assembly to smoothly receive the redundant fertilizer; A redundant material release assembly is also installed on the redundant material receiving assembly. After the redundant material receiving assembly receives the redundant fertilizer, the redundant material release assembly is used for releasing the redundant fertilizer to collect the redundant material.

[0005] Further, a discharge pipe is fixedly arranged at the lower end of the storage bin, and a controller and an electromagnetic valve are fixedly installed on the discharge pipe. The controller is used for controlling the work of the electromagnetic valve.

[0006] Further, the redundant material receiving assembly comprises a hydraulic rod, and the hydraulic rod is controlled by the controller. A rotating support strip is fixedly arranged with a receiving table. The connecting slide plate is movably mounted on the rotating support bar, and the movable connection between the rotating support bar and the hydraulic rod is achieved through the connecting slide plate.

[0007] Further, the rotating support bar is driven to rotate by the hydraulic rod. The excess fertilizer is received by the receiving table, and the upper surface of the receiving table is provided with a receiving slope.

[0008] Further, the receiving closing assembly comprises a first L-shaped slide plate movably mounted on the rotating support bar. The movable closing plate is movably mounted on the receiving table.

[0009] Further, when the rotating support bar rotates to receive the excess fertilizer through the receiving table, the first L-shaped slide plate moves relative to the rotating support bar under the action of the connecting slide plate.

[0010] Further, the first L-shaped slide plate and the movable closing plate are movably connected, and the movable closing plate moves relative to the receiving table through the first L-shaped slide plate, so as to close and open one side of the receiving table.

[0011] Further, the excess material releasing assembly comprises a second L-shaped slide plate movably mounted on the rotating support bar. The push-up supporting plate is movably mounted on the receiving table, and the push-up supporting plate is movably connected with the second L-shaped slide plate, and the push-up supporting plate moves relative to the receiving table through the second L-shaped slide plate. The movable discharging plate is also movably mounted on the receiving table.

[0012] Further, when the rotating support bar rotates to release the excess fertilizer, the second L-shaped slide plate moves relative to the rotating support bar under the action of the connecting slide plate, and the movable discharging plate rotates relative to the receiving table through the push-up supporting plate, so that the other side of the receiving table is opened.

[0013] A method for using a fertilizer releasing device, comprising the following steps: Step one: receiving the excess material: after the packaging bag quantitatively receives the fertilizer, the controller controls the hydraulic rod to move, and then drives the rotating support bar to rotate so that the receiving table rotates to the directly below the discharge pipe to receive the excess material; Step two: transferring the excess material: after the excess fertilizer is received on the receiving table, the rotating support bar is reversely rotated under the action of the hydraulic rod, and the received excess fertilizer is transferred away. Step three: collection of excess material: on the basis of step two, the rotation of the rotating support bar will make the movable discharging plate rotate relative to the receiving table, so that the receiving table is opened, and the excess fertilizer is released and collected.

[0014] Compared with the prior art, the present application has the advantages of reasonable structure and strong functionality, and has the following advantages: 1. A receiving table is arranged on the lower side of the discharge pipe. When the amount of the fertilizer in the packaging bag reaches the specified amount, the receiving table will rotate below the discharge pipe to receive the falling fertilizer, avoiding the fertilizer falling into the packaging bag, and further reducing the quantitative error.

[0015] 2. The receiving table moves the movable closing plate during the rotation of the receiving table. The movable closing plate can close the side of the receiving table to prevent the fertilizer from falling, and the fertilizer falls from the movable closing plate and the receiving table into the packaging bag during the receiving process. This arrangement can prevent the side wall of the receiving table from knocking the fertilizer when the receiving table rotates below the discharge pipe.

[0016] 3. In addition, after the receiving table receives the fertilizer, it rotates to one side of the discharge pipe, so that it rotates above the collection box. When it rotates above the collection box, the movable discharging plate rotates relative to the receiving table, so that the receiving table is in an open state, and the fertilizer can slide down into the collection box for collection, which is very convenient.

The connecting slide plate 3 is movably connected with the rotating support bar 2 through the cooperation of the first slide hole 31 and the cavity inner support rod 23. The connecting slide plate 3 is hinged with the connecting strip block 193. Thus, the rotating support bar 2 is movably connected with the hydraulic rod 191.

[0040] When the hydraulic rod 191 is stretched or retracted, the connecting slide plate 3 is moved. Thus, the rotating support bar 2 is rotated under the action of the connecting slide plate 3. The relative movement between the connecting slide plate 3 and the rotating support bar 2 is realized.

[0044] When the rotating support bar 2 rotates to receive excess fertilizer through the receiving table 24, the first L-shaped sliding plate 4 and the rotating support bar 2 move relatively under the action of the connecting sliding plate 3.

[0045] The first L-shaped sliding plate 4 and the movable closing plate 5 are movably connected, the movable closing plate 5 is moved relative to the receiving table 24 by the first L-shaped sliding plate 4, the closing and opening of one side of the receiving table 24 is realized, specifically, one first driving cantilever rod 45 is hinged to the movable closing plate 5, and the other first driving cantilever rod 45 is hinged to the connecting convex strip 52, and the movable connection between the first L-shaped sliding plate 4 and the movable closing plate 5 is realized through the first driving cantilever rod 45.

[0046] As shown in the drawings, Figure 6 , Figure 8 , Figure 9 , Figure 12 , Figure 13 and Figure 14As shown, the excess material releasing assembly comprises a second L-shaped sliding plate 6, a pushing and supporting plate 7 and a movable discharging plate 8. The second L-shaped sliding plate 6 is movably mounted on the rotating support strip 2. Specifically, a third sliding hole 61 is formed in the second L-shaped sliding plate 6, and a cavity supporting rod 23 is inserted into the third sliding hole 61. A second driving supporting rod 62 is welded and fixed to the lower end of the second L-shaped sliding plate 6. The second driving supporting rod 62 is inserted into a supporting channel 28 on the other support bottom strip 27, and is further supported by the supporting channel 28. A second matching spring 63 is sleeved on the cavity supporting rod 23. One end of the second matching spring 63 is welded and connected with the inner wall of the moving cavity 22, and the other end is welded and connected with the second L-shaped sliding plate 6.

[0047] The other end of the second driving supporting rod 62, away from the second L-shaped sliding plate 6, is welded and fixed with a second connecting block 64 by welding process. The second connecting block 64 is hingedly connected with a second driving cantilever rod 65. A limiting bent plate 66 is welded and fixed to the second driving supporting rod 62 by welding process.

[0048] The pushing and supporting plate 7 is movably mounted on the material receiving table 24. Specifically, a pushing and supporting column 71 is integrally formed and fixed on the pushing and supporting plate 7. A matching insertion hole 73 is formed in the pushing and supporting plate 7, and extends to the pushing and supporting column 71. A matching supporting rod 29 is inserted into the matching insertion hole 73. The pushing and supporting plate 7 is movably mounted on the material receiving table 24 through the cooperation of the matching insertion hole 73 and the matching supporting rod 29.

[0049] The pushing and supporting plate 7 is movably connected with the second L-shaped sliding plate 6. The pushing and supporting plate 7 is moved relative to the material receiving table 24 through the second L-shaped sliding plate 6. Specifically, a connecting frame plate 72 is welded and fixed on the pushing and supporting plate 7 by welding process. The connecting frame plate 72 is hingedly connected with the second driving cantilever rod 65. The movable connection between the pushing and supporting plate 7 and the second L-shaped sliding plate 6 is realized through the second driving cantilever rod 65.

[0050] The movable discharging plate 8 is movably hingedly connected to the side of the material receiving table 24 away from the movable closing plate 5, and is located at the lower side of the material receiving inclined surface 25. When the material receiving table 24 is closed, the movable discharging plate 8 is in a vertical state and is in contact with the material receiving table 24. At this time, the limiting bent plate 66 is in contact with the movable discharging plate 8 and limits the movement of the movable discharging plate 8.

[0051] When the rotating support strip 2 rotates to release the excess fertilizer, the second L-shaped sliding plate 6 moves relative to the rotating support strip 2 under the action of the connecting sliding plate 3. The movable discharging plate 8 is rotated relative to the material receiving table 24 by the pushing and supporting column 71 on the pushing and supporting plate 7, so that the other side of the material receiving table 24 is opened.

[0052] A method for using a fertilizer release device, comprising the following steps: Step one: receiving the excess fertilizer: after the packaging bag is quantitatively filled with fertilizer, the controller 161 controls the hydraulic rod 191 to move, thereby driving the rotating support bar 2 to rotate so that the receiving table 24 is rotated to be directly below the discharge pipe 16 to receive the falling excess fertilizer; Step two: transferring the excess fertilizer: after the excess fertilizer is received on the receiving table 24, the rotating support bar 2 is reversely rotated under the action of the hydraulic rod 191 to transfer the received excess fertilizer away; Step three: collecting the excess fertilizer: based on step two, the rotating of the rotating support bar 2 will make the movable discharge plate 8 rotate relative to the receiving table 24 to open the receiving table 24, and the excess fertilizer is released and collected.

[0053] When the weighing device 13 detects that the fertilizer in the packaging bag reaches the set weight, it transmits this information to the controller 161 at this time, the controller 161 controls the electromagnetic valve 162 to close, and at the same time controls the hydraulic rod 191 to extend to drive the connecting slide plate 3 to move, thereby driving the rotating support bar 2 to rotate so that the receiving table 24 is rotated to be directly below the discharge pipe 16 for receiving the excess fertilizer falling, and before this, the packaging bag receives the fertilizer, the fertilizer falls from between the receiving table 24 and the movable closing plate 5 in the packaging bag.

[0054] During the rotation of the receiving table 24 to be directly below the discharge pipe 16, the connecting slide plate 3 will move relative to the rotating support bar 2, thereby pushing the first L-shaped slide plate 4 to move relative to the rotating support bar 2 under the action of the connecting slide plate 3, and moving the first L-shaped slide plate 4 away from the second L-shaped slide plate 6, so that the movable closing plate 5 is moved to the direction of the receiving table 24 under the action of the first drive cantilever rod 45, thereby closing one side of the receiving table 24, so that the excess fertilizer can be successfully received on the receiving table 24, and the movable setting of the movable closing plate 5 can effectively avoid the receiving table 24 from colliding with the fertilizer under the action of its side wall when rotating to be directly below the discharge pipe 16, thereby preventing the fertilizer from being scattered, and most of the excess fertilizer can be effectively received by the receiving table 24, further reducing the quantitative error of the packaging bag, in addition, the received fertilizer is concentrated on one side of the movable discharge plate 8 under the action of the receiving slope 25.

[0055] After the excess fertilizer is received, the hydraulic rod 191 is retracted to drive the rotating support bar 2 to reverse rotation. With the reverse rotation of the rotating support bar 2, the first L-shaped slide plate 4 is reset under the action of the first matching spring 43, thereby driving the movable closing plate 5 to reset, and at the same time, the rotating support bar 2 drives the receiving table 24 to rotate above the collection box 12. When the receiving table 24 rotates above the collection box 12, the connecting slide plate 3 will contact the second L-shaped slide plate 6, so that the second L-shaped slide plate 6 and the rotating support bar 2 will move relatively under the action of the connecting slide plate 3, thereby driving the second connecting block 64 to move towards the receiving table 24, and under the action of the second drive cantilever rod 65, the push top plate 7 moves away from the support bottom bar 27, and at the same time, the limiting bent plate 66 separates from the movable discharging plate 8 with the movement of the second L-shaped slide plate 6. Then, the push top column 71 contacts the movable discharging plate 8 with the further movement of the second L-shaped slide plate 6, so that the movable discharging plate 8 rotates relative to the receiving table 24 under the action of the push top column 71, thereby making the receiving table 24 in a stable open state, so that the excess fertilizer on the receiving table 24 can fall into the collection box 12 to realize collection.

[0056] When the excess fertilizer is collected, the hydraulic rod 191 can drive the rotating support bar 2 to reset. In the resetting process, the second L-shaped slide plate 6 is reset under the action of the second matching spring 63, and at the same time, the movable discharging plate 8 rotates and resets under the action of its own gravity to close the receiving table 24 again, and then the limiting bent plate 66 contacts the movable discharging plate 8 again to limit it, thereby ensuring its stability.
