Description

Technical Field

[0001] The invention relates to the technical field of fertilizer spreaders, in particular to a fertilizer spreader with an anti-blocking device. Background Art

[0002] Fertilization is a method of adding nutrients needed by crops to the soil. Fertilization not only needs to meet the nutrient requirements of crops, but also requires continuously improving soil fertility through fertilization. To achieve reasonable fertilization, we should follow the principles of "fertilizing according to the weather", "fertilizing according to the soil" and "fertilizing according to the crops". Fertilizer spreaders are usually used to complete fertilization operations.

[0003] For some crops that are planted densely and regularly, continuous and uniform fertilization is required along their gullies, while for some crops that are planted relatively sparsely, segmented fertilization is required. On the one hand, the fertilizer is applied around the root system of the crop to facilitate the complete absorption and utilization of the fertilizer effect, and on the other hand, it is avoided that the fertilizer is applied to the area without crops and waste is caused. Whether the existing fertilizer spreaders are performing continuous fertilization or segmented fertilization, most of the fertilizer falls by its own gravity in the storage bin. A small part of the fertilizer falls by relying on the vibration of the fertilizer spreader. The gravity changes due to the constant change in the capacity of the fertilizer in the storage bin. Secondly, the speed and terrain of the fertilizer spreader are unstable. Moreover, factors such as the different sizes of fertilizer particles can easily lead to blockage of fertilizer feeding.

[0004] Technical Solution

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fertilizer spreader with an anti-blocking device, comprising an integrally installed frame, wheels and a storage bin, wherein a belt shaft 1 coaxial with the wheel is provided at one end of the central axis of the wheel, a pulley 2 is provided on the side surface of the storage bin directly above the belt shaft 1, a belt is sleeved between the pulley 2 and the belt shaft 1, a protective box is fixedly installed on the inner walls of both sides of the storage bin, the other end of the pulley 2 movably penetrates into the interior of the storage bin and is fixedly connected to a disc, a connecting rod 1 is movably provided on the outer surface of the disc, the disc and the connecting rod 1 are both located in the protective box, one end of the connecting rod 1 is movably connected to a connecting rod 2, the top end of the connecting rod 2 movably penetrates into the top of the protective box and is fixedly installed with a cross bar, a plurality of dredging rods are evenly arranged on the bottom end of the cross bar, and a plurality of material receiving parts corresponding to the dredging rods are arranged at the bottom of the storage bin.

[0006] Preferably, the material receiving member is composed of a hopper and a conduit, and the bottom hopper is mounted on the bottom side wall of the storage bin by bolts.

[0007] Preferably, a plurality of card slots are provided on an inner wall of one side of the storage bin near its bottom end, and a movable plate is movably provided on the inner wall of the other side of the storage bin, and a plurality of card plates extending into the card slots are fixedly connected to the side surface of the movable plate.

[0008] Preferably, the gap between each two adjacent clamping plates is equal, and they serve as material discharge openings and correspond to the top opening of the material receiving piece up and down, and a gap is provided between the clamping plates and the material receiving piece.

[0009] Preferably, both ends of the movable plate are connected to a rack plate through an axle rod, the rack plate is attached to the outer surface of the storage bin, and the two side walls of the storage bin are respectively provided with limit grooves for the horizontal movement of the axle rod.

[0010] Preferably, the outer surface of the storage bin is also rotatably provided with a half gear meshing with the rack plate, and the outer surface of the half gear is evenly provided with a plurality of bolt columns near its edge, and the outer surface of the storage bin is also provided with a plurality of limiting holes for the bolt columns to extend through.

[0011] Preferably, a connecting plate 2 is movably sleeved on the outer surface of one of the bolt columns, a connecting plate 1 is movably connected to the bottom end of the connecting plate 2, and the other end of the connecting plate 1 is fixedly connected to one end of the belt shaft 1.

[0012] Preferably, two movable plates are fixedly provided on one side surface, and a limiting hole is opened on one side wall of the storage bin for movable penetration. A folding plate is fixedly connected between the top of the movable plate and the inner wall of one side of the storage bin, and a material guide plate fixedly connected to the inner wall of the storage bin is also provided above the folding plate.

[0013] Beneficial Effects

[0014] Compared with the prior art, the present invention provides a fertilizer spreader with an anti-clogging device, which has the following beneficial effects:

[0015] By respectively arranging pulleys on the wheel and the side wall of the storage bin, the two pulleys are connected by a belt. When the fertilizer spreader is moving, the pulleys are driven by the wheels to rotate synchronously, thereby driving the disc arranged on the inner wall of the storage bin to rotate synchronously. The disc then drives the connecting rod two to move up and down in a cycle through the connecting rod one, and the connecting rod two will drive the cross bar and the dredging rod to move up and down in a cycle. The bottom end of the dredging rod can be circulated into the material receiving piece, so as to achieve the effect of constantly dredging the material receiving piece, thereby avoiding blockage during the fertilization process.

[0016] When the wheel moves, it drives connecting plate one to rotate, and connecting plate one pulls the half gear through connecting plate two in a reciprocating cycle. The reciprocating motion of the half gear drives the rack plate meshing with it to move back and forth synchronously, so that the rack plate drives the movable plate to circulate horizontally. When the movable plate fits with the slot, the unloading port of the storage bin is closed. When there is a gap between the movable plate and the slot, the fertilizer falls into the receiving piece along the gap between the two adjacent plates, thereby achieving the effect of intermittent fertilization. It is suitable for fertilizing soil with sparse crops.

[0017] By sleeve-connecting the second connecting plate on different bolt columns, the effect of adjusting the fertilization interval can be achieved. When continuous and uniform fertilization is performed, the disc is removed from the bolt column, the distance between the movable plate and the slot is adjusted, and then the bolt column is rotated to penetrate into the corresponding limiting hole 1, so as to achieve the effect of fixing the blanking size.

[0030] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] like Figure 1-9 As shown in the figure, it is an embodiment of the present invention. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fertilizer spreader with an anti-blocking device, comprising an integrally installed frame 1, a wheel 2 and a storage bin 3, one end of the central axis of the wheel 2 is provided with a belt shaft 21 coaxial therewith, when the fertilizer spreader moves, the wheel 2 drives the belt shaft 21 to rotate synchronously, the side surface of the storage bin 3 is located directly above the belt shaft 21 and is provided with a pulley 2 31, a belt 5 is sleeved between the pulley 2 31 and the belt shaft 21, the belt shaft 21 and the pulley 2 31 can rotate synchronously through the belt 5, a protective box 35 is fixedly installed on the inner walls of both sides of the storage bin 3, the other end of the pulley 2 31 movably penetrates into the interior of the storage bin 3 and is fixedly connected to a disc 32, the outer surface of the disc 32 is movably provided with a connecting rod 33, and the connecting rod 33 is provided with a connecting rod 33. The disk 32 and the connecting rod 1 33 are both located in the protective box 35. One end of the connecting rod 1 33 is movably connected to a connecting rod 2 34. The top of the connecting rod 2 34 movably penetrates through the protective box 35 and is fixedly installed with a cross bar 4. A plurality of dredging rods 41 are evenly arranged at the bottom of the cross bar 4. A plurality of material receiving pieces 8 corresponding to the dredging rods 41 are arranged at the bottom of the storage bin 3. The pulley 2 31 drives the disk 32 to rotate synchronously, and then the connecting rod 1 33 can drive the connecting rod 2 34 to move up and down in a cycle. The connecting rod 2 34 will drive the cross bar 4 and the dredging rod 41 to move up and down in a cycle. Since the bottom end of the dredging rod 41 is directly connected to the top opening of the material piece 8, the bottom end part of the dredging rod 41 can directly pass into the material receiving piece 8 when the dredging rod 41 moves up and down in a cycle, thereby achieving the effect of dredging the material receiving piece 8 at all times, thereby avoiding blockage during fertilization.

[0032] Furthermore, the material receiving member 8 is composed of a hopper and a conduit. The bottom hopper is mounted on the bottom side wall of the storage bin 3 by bolts and can be installed and disassembled. The conduit of the material receiving member 8 is vertically arranged to facilitate material unloading.

[0033] Furthermore, a plurality of slots 38 are provided on the inner wall of one side of the storage bin 3 near its bottom end, and a movable plate 7 is movably provided on the inner wall of the other side of the storage bin 3. A plurality of clips 71 are fixedly connected to the side surface of the movable plate 7 and extend into the slots 38 respectively. The gap between each two adjacent clips 71 is equal, and they are used as feed ports and correspond to the top opening of the material receiving piece 8 up and down. A gap is provided between the clips 71 and the material receiving piece 8, so when the movable plate 7 drives the clips 71 to move horizontally, no friction is generated with the material receiving piece 8. The top opening size of the material receiving piece 8 is larger than the maximum gap between each two clips 71, so as to prevent the fertilizer from falling along the outside of the material receiving piece 8.

[0034] Among them, both ends of the movable plate 7 are connected to a rack plate 72 through an axis rod, the rack plate 72 is attached to the outer surface of the storage bin 3, and the two side walls of the storage bin 3 are respectively provided with limiting grooves 36 for horizontal movement of the axis rod. When the movable plate 7 drives the rack plate 72 to move horizontally, the axis rod used to connect the two slides horizontally in the limiting groove 36.

[0035] Furthermore, the outer surface of the storage bin 3 is also rotatably provided with a half gear 6 meshing with the rack plate 72, and the outer surface of the half gear 6 is evenly provided with a plurality of bolt columns 61 near its edge position, and the outer surface of the storage bin 3 is also provided with a plurality of limit holes 37 for the bolt columns 61 to extend and penetrate, and the outer surface of one of the bolt columns 61 is movably sleeved with a connecting plate 23, and the bottom end of the connecting plate 23 is movably connected with a connecting plate 22, and the other end of the connecting plate 22 is fixedly connected to one end of the belt shaft 21, and the belt shaft 21 and the connecting plate 22 are driven to rotate synchronously when the wheel 2 moves, and the connecting plate 22 pulls the half gear 6 through the connecting plate 23 in a reciprocating cycle, and the reciprocating motion of the half gear 6 drives the rack plate 72 meshing with it to move synchronously in a reciprocating cycle, thereby causing the rack plate 72 to drive the movable The plate 7, the card plates 71 and the 73 move synchronously, so that the card plate 71 moves cyclically inside the card slot 38, and the movable plate 7 moves cyclically close to and away from the card slot 38. When the movable plate 7 is in contact with the card slot 38, the discharge port of the storage bin 3 is closed. When there is a gap between the movable plate 7 and the card slot 38, the fertilizer falls into the material receiving member 8 along the gap between the two adjacent card plates 71, thereby achieving the effect of intermittent fertilization, which is suitable for fertilizing soil with sparse crops. By sleeve-connecting the connecting plate 23 on different bolt columns 61, the effect of adjusting the fertilization gap can be achieved. When continuous and uniform fertilization is performed, the disc 32 is removed from the bolt column 61, and after adjusting the distance between the movable plate 7 and the card slot 38, the bolt column 61 is rotated until it penetrates into the corresponding limit hole 1 37, thereby achieving the effect of fixing the discharge size.

[0036] Furthermore, two 73 are fixedly provided on one side surface of the movable plate 7, and a limiting hole 39 is also provided on one side wall of the storage bin 3 for movable penetration 73. When the movable plate 7 drives the card plate 71 to move horizontally in a cyclical manner, 73 always passes through the limiting hole 39, further ensuring the dynamic stability of the movable plate 7 and the card plate 71. A folding plate 9 is fixedly connected between the top of the movable plate 7 and the inner wall of one side of the storage bin 3. When the movable plate 7 moves horizontally in a cyclical manner, it will drive the folding plate 9 to fold and deform to a certain extent. The folding plate 9 can prevent the fertilizer inside the storage bin 3 from being discharged from other places. A guide plate 10 fixedly connected to the inner wall of the storage bin 3 is also provided above the folding plate 9. The guide plate 10 is an inclined structure and is mainly used for guiding materials obliquely downward. Secondly, the guide plate 10 is made of stainless steel and has a certain hardness, which can protect the folding plate 9 and prevent a large amount of fertilizer from contacting the folding plate 9 and affecting its performance.

[0037] When the above embodiment is working, the fertilizer is poured into the storage bin 3, and the wheel 2 drives the belt shaft 21 and the connecting plate 22 to rotate synchronously when moving. The connecting plate 22 pulls the half gear 6 through the connecting plate 23 in a reciprocating cycle. The reciprocating motion of the half gear 6 drives the rack plate 72 meshing with it to move back and forth in a synchronous cycle, and then the rack plate 72 drives the movable plate 7, the clamping plates 71 and 73 to move synchronously, so that the clamping plate 71 moves cyclically inside the clamping groove 38, and the movable plate 7 moves cyclically close to and away from the clamping groove 38. When the movable plate 7 is in contact with the clamping groove 38, the discharge port of the storage bin 3 is closed. When there is a gap between the movable plate 7 and the clamping groove 38, the fertilizer falls into the material receiving piece 8 along the gap between the two adjacent clamping plates 71, thereby achieving the effect of intermittent fertilization, which is suitable for fertilizing sparse soil with crops. By sleeve-connecting the connecting plate 23 on different bolt columns 61, the effect of adjusting the fertilization gap can be achieved. When continuous and uniform fertilization is carried out, the disc 32 is removed from the bolt column 61, and after adjusting the distance between the movable plate 7 and the slot 38, the bolt column 61 is rotated to penetrate into the corresponding limit hole 37 to achieve the effect of fixing the material size. The belt 5 is sleeved on the pulley 2 31 and the belt shaft 1 21, and the pulley 2 31 drives the disc 32 to rotate synchronously, and then the connecting rod 1 33 can drive the connecting rod 2 34 to move up and down in a cycle, and the connecting rod 2 34 will drive the cross bar 4 and the dredging rod 41 to move up and down in a cycle. Since the bottom end of the dredging rod 41 is directly connected to the top opening of the material piece 8, the bottom end part of the dredging rod 41 can directly pass into the material receiving piece 8 when the dredging rod 41 moves up and down in a cycle, so as to achieve the effect of dredging the material receiving piece 8 at all times, thereby avoiding blockage during fertilization.
