Description

Technical Field

[0001] The present invention relates to the technical field of fertilization, and more particularly to a fully automatic fertilization device for agricultural machinery. Background Art

[0002] In modern agricultural production, the planting of sowing crops covers two main sowing methods: fixed-point pre-buried and broadcasting. These two sowing methods have their own characteristics. Fixed-point pre-buried can accurately place seeds in a specific position and provide a stable environment for the initial growth of seeds. Broadcasting is more suitable for large-scale planting and can improve sowing efficiency. For crops sown with fixed-point pre-buried seeds, the fertilization process requires precise and fixed-point fertilizer placement to ensure the optimal distance between fertilizer and seeds and nutrient supply. For broadcasting crops, fertilization needs to be scattered.

[0003] The existing fertilization devices have relatively single functions and can often only realize one of the functions of spreading fertilizer or placing fertilizer at a fixed point. In the actual planting process, farmers need to frequently replace fertilization equipment due to different fertilizer requirements of different crop varieties and different growth stages.

[0021] like Figures 1 to 4 As shown, the present invention relates to a fully automatic fertilizing device for agricultural machinery, comprising a drone 1, a storage mechanism 2, a fertilizing mechanism 3 and a stirring mechanism 4.

[0022] In an embodiment of the present invention, Figure 1 As shown, the drone 1 used for fertilization is a prior art and will not be described in detail here.

[0023] In an embodiment of the present invention, Figure 2 and Figure 3 As shown, the storage mechanism 2 includes a storage barrel 21, which is arranged below the drone 1. The storage barrel 21 is fixedly connected to the drone 1 through a plurality of fixing claws 22, and a discharge pipe 23 is connected to the bottom of the storage barrel 21. It is worth mentioning that a valve is arranged on the discharge pipe 23, and the valve structure is a prior art and will not be described in detail here.

[0024] As another embodiment of the present invention, Figures 3 to 10As shown, the fertilizing mechanism 3 includes a fixed cylinder 31, a fixed ring 32, an outer ring 33, an inner ring 34, a centrifugal block 35, a plurality of bottom plates 36 and a plurality of functional plates 37; The fixed cylinder 31 is fixedly mounted at the bottom end of the discharge pipe 23; The fixing ring 32 is fixedly arranged at the bottom end of the fixing cylinder 31. A plurality of triangular grooves A321 are formed in a circular equidistant structure on the inner edge of the fixing ring 32. A limiting column A322 is movably connected in the triangular groove A321. The depth of the triangular groove A321 gradually becomes shallower in the clockwise direction. The limiting column A322 is elastically connected to the deep part of the triangular groove A321 through a spring A323. The outer ring 33 is rotatably arranged on the inner edge surface of the fixed ring 32, and the outer edge surface of the outer ring 33 is movably connected with the limiting column A322; through the above arrangement, the present invention makes it possible that in the initial state, the limiting column A322 contacts the outer edge surface of the outer ring 33 under the elastic force of the spring A323, so that when the outer ring 33 rotates reversely relative to the fixed ring 32, the friction force of the outer ring 33 on the limiting column A322 makes the limiting column A322 have the force to move toward the deep part of the triangular groove A321, and the limiting column A322 has little effect on the reverse rotation of the outer ring 33. Therefore, the outer ring 33 can rotate reversely relative to the fixed ring 32. If the outer ring 33 rotates forwardly relative to the fixed ring 32, the friction force of the outer ring 33 on the limiting column A322 makes the limiting column A322 have the force to move toward the shallow part of the triangular groove A321, so that the fixed ring 32 locks the outer ring 33 through the limiting column A322, so the outer ring 33 cannot rotate forward.

[0025] The inner ring 34 is rotatably arranged on the inner edge surface of the outer ring 33. The outer edge surface of the inner ring 34 is provided with a plurality of triangular grooves B341 in an annular structure with equal spacing. The triangular grooves B341 are movably connected with the limiting pillars B342. The depth of the triangular grooves B341 gradually becomes shallower in the clockwise direction. The limiting pillars B342 are elastically connected to the deep part of the triangular grooves B341 through springs B343. The inner edge surface of the outer ring 33 is movably connected with the limiting pillars B342. The bottom end of the inner ring 34 is provided with V-shaped guide grooves 340 and arc guide grooves 341. 44, a V-shaped guide groove 340 and an arc guide groove 344 are connected to form a closed-loop displacement guide groove, a plurality of movable rings 345 are movably connected to the displacement guide groove, a round block 346 is provided at the center of the inner ring 34, and the inner ring 34 and the round block 346 are fixedly connected by triangular rods 347 arranged in a ring-shaped equidistant structure; through the above arrangement, referring to the rotation principle of the outer ring 33, it can be known that the inner ring 34 can rotate in the forward direction relative to the outer ring 33, and the inner ring 34 and the outer ring 33 can rotate in the reverse direction as a whole.

[0026] The centrifugal block 35 is fixedly arranged at the bottom end of the outer ring 33. The centrifugal block 35 is composed of a plurality of centrifugal plates 351 arranged in a circular equidistant structure. The number of the plurality of centrifugal plates 351 is equal to the number of the plurality of movable rings 345, and the angle of the V-shaped guide groove 340 is smaller than the angle formed by two adjacent centrifugal plates 351. The centrifugal plates 351 are fixedly connected to the centripetal ends. The gap between the two adjacent centrifugal blocks 35 forms a centrifugal cavity. Angle blocks 352 are fixedly arranged at both ends of one side of the bottom of the centrifugal plate 351. The gap between two adjacent angle blocks 352 on the two adjacent centrifugal blocks 35 forms a rotating cavity. A slide groove 353 is provided at the bottom of the centrifugal plate 351. A beveled tooth plate 354 is slidably connected in the slide groove 353. A rotating groove 355 is connected to the top of the eccentric side of the slide groove 353. A missing gear 356 is rotatably provided on the rotating groove 355. The missing gear 356 is meshed with the beveled tooth plate 354. A movable groove 357 is provided at the top of the centrifugal plate 351. The movable groove 35 The bottom end of the movable groove 357 is connected to the centripetal side of the rotating groove 355, and a movable column 358 is movably connected to the movable groove 357. The two ends of the movable column 358 are rotatably connected to the bevel gear plate 354 and the movable ring 345 respectively. A limited rotation groove 359 is provided at the top of the eccentric side of the centrifugal block 35. Through the above arrangement, the present invention, because the angle of the V-shaped guide groove 340 is smaller than the angle formed by the two adjacent centrifugal plates 351, when one of the movable rings 345 moves on the V-shaped guide groove 340, the other movable rings 345 are all located on the arc guide groove 344, so that the inner ring 34 rotates forward relative to the outer ring 33, and when one of the movable rings 345 moves on the V-shaped guide groove 340, the corresponding movable column 358 moves on the movable groove 357, driving the bevel gear plate 354 to slide in the slide groove 353, so that the missing gear 356 rotates, and the inner ring 34 continues to rotate forward relative to the outer ring 33, and a plurality of missing gears 356 rotate reciprocatingly in sequence intermittently.

[0027] The bottom plate 36 includes a transverse plate 361, and a plurality of transverse plates 361 are respectively arranged in a plurality of rotating chambers. Connecting rods 362 are fixedly provided at both ends of the transverse plate 361. The connecting rods 362 are rotatably connected to the corner blocks 352. One of the connecting rods 362 penetrates into the corresponding rotating groove 355 and is fixedly connected to the missing gear 356. A triangular plate 363 adapted to the centrifugal chamber is fixedly provided at one centripetal end of the transverse plate 361. The triangular plate 363 is arranged in an inclined structure. The triangular plate 363 and the centrifugal chamber form a material equalizing chamber. Through the above arrangement, the present invention enables the rotation of the missing gear 356 to drive the connecting rod 362, the cross plate 361 and the triangular plate 363 to rotate, and when the plurality of movable rings 345 are all located at the initial positions of the arc guide groove 344, the inner ring 34 and the outer ring 33 rotate rapidly in the opposite direction as a whole, and the overall rotation can drive the centrifugal block 35 and the bottom plate 36 to rotate, forming a centrifugal fertilization state. When the inner ring 34 continues to rotate slowly in the forward direction relative to the outer ring 33, the plurality of bottom plates 36 intermittently rotate back and forth in sequence, so that the fertilizers in the plurality of equalizing cavities intermittently fall in sequence, and cooperate with the movement of the drone 1 to form a fixed-point fertilization state. In addition, the present invention arranges the triangular plate 363 in an inclined structure, so that the triangular plate 363 and the centrifugal cavity form a triangular cone-shaped equalizing cavity. In the fixed-point fertilization state, the fertilizer is not easy to leak.

[0028] The function plate 37 is movably arranged on the position-limiting rotating groove 359. The function plate 37 is adapted to the shape of the centrifugal plate 351. The bottom end of the function plate 37 is rotatably connected to a rotating rod 371. The bottom end of the rotating rod 371 is fixedly connected to the position-limiting rotating groove 359. A circular groove 372 is provided in the function plate 37. The top end of the rotating rod 371 is elastically connected to the circular groove 372 through a torsion spring 373. A plurality of mounting grooves 374 are evenly provided on the function plate 37. A gravity column 375 is fixed on the mounting groove 374. In the initial state and the fixed-point fertilization state, the present invention can be realized by setting the function plate 37. Figure 7 As shown, under the elastic force of the torsion spring 373, the function plate 37 provides a barrier for the material distribution chamber to prevent the fertilizer from leaking. The inner ring 34 and the outer ring 33 rotate rapidly in the opposite direction as a whole. When the whole rotates, the function plate 37 rotates under the action of centrifugal force until it contacts the upper side of the limit groove 359, forming an extended wall of the centrifugal plate 351, and the inclined triangular plate 363 allows part of the fertilizer to be centrifugally thrown out in an upward direction along the surface of the centrifugal plate 351 and the function plate 37. This part of the fertilizer is centrifugally thrown out along a parabola, which increases the throwing distance of the fertilizer, thereby improving the effect of fertilization.

[0029] In an embodiment of the present invention, Figures 2 to 4As shown, the stirring mechanism 4 includes a motor 41, a stirring shaft 42, a plurality of stirring units 43 and a connecting shaft 44. The motor 41 is fixedly arranged at the top of the storage barrel 21, the connecting shaft 44 is rotatably arranged in the storage barrel 21, the top of the connecting shaft 44 passes through the storage barrel 21 and is fixedly connected to the output shaft of the motor 41, a plurality of stirring units 43 are evenly fixedly arranged on the surface of the stirring shaft 42, the connecting shaft 44 is arranged in the discharge pipe 23, and the two ends of the connecting shaft 44 are respectively fixedly connected to the stirring shaft 42 and the round block 346. The present invention is arranged through the stirring mechanism 4, so that the output shaft of the motor 41 is controlled to rotate by an external control mechanism, and the plurality of stirring units 43, the connecting shaft 44 and the threaded block 45 are all rotated, and the stirring unit 43 stirs the fertilizer in the storage barrel 21, breaks up the fertilizer agglomerated in the storage barrel 21, and makes the fertilizer agglomerated in the storage barrel 21 in a flowing state, so that the fertilizer falls from the discharge pipe 23, and the rotation of the connecting shaft 44 drives the round block 346 to rotate, so that the inner ring 34 rotates. The present invention adopts the structural design of the fertilizing mechanism 3 and the stirring mechanism 4 so that the output shaft of the motor 41 can be externally controlled to rotate forward and reverse without adjustment, and both the fixed-point fertilization and the centrifugal fertilization can be remotely controlled. The present invention has a high degree of automation and is easy to use.

[0030] Working principle: This embodiment provides a fully automatic fertilizing device for agricultural machinery. When centrifugally spreading fertilizer, the output shaft of the motor 41 is controlled by an external control mechanism to rotate rapidly in the reverse direction, and a plurality of stirring units 43, a connecting shaft 44 and a threaded block 45 are all rotated. The stirring unit 43 stirs the fertilizer in the storage barrel 21, breaks up the fertilizer agglomerated in the storage barrel 21, and makes the fertilizer agglomerated in the storage barrel 21 flow. The fertilizer falls from the discharge pipe 23 to a plurality of material distribution chambers, and the rotation of the connecting shaft 44 drives the round block 346 to rotate, so that the inner ring The outer ring 34 rotates rapidly in the opposite direction as a whole, driving the centrifugal block 35 and the bottom plate 36 to rotate rapidly. The function plate 37 rotates under the action of centrifugal force until it contacts the upper side of the limit rotating groove 359, forming an extended wall of the centrifugal plate 351. The fertilizer is centrifugally thrown out from the material distribution cavity, and the inclined triangular plate 363 makes part of the fertilizer centrifugally thrown out in an oblique upward direction along the surface of the centrifugal plate 351 and the function plate 37. This part of the fertilizer is centrifugally thrown out along a parabola, thereby increasing the throwing distance of the fertilizer, thereby improving the effect of throwing fertilization; When fertilizing at a fixed point, the output shaft of the motor 41 is controlled by an external control mechanism to rotate slowly in the forward direction, and the round block 346 rotates in the forward direction, so that the inner ring 34 rotates in the forward direction relative to the outer ring 33, and the outer ring 33 does not rotate. At this time, under the elastic force of the torsion spring 373, the functional plate 37 provides a barrier for the material distribution cavity to prevent the fertilizer from leaking, and several bottom plates 36 rotate back and forth intermittently in sequence, so that the fertilizer in the several material distribution cavities falls intermittently in sequence, cooperating with the movement of the drone 1 to form a fixed-point fertilization state.
