Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly relates to a multi-scenario compatible fertilizer spreader with a feeding mechanism. Background Art

[0002] The fertilizer spreader is fixed at the rear of the agricultural machinery and is used to distribute and scatter fertilizers in the field. During operation, the fertilizer spreader needs to scatter a large amount of organic fertilizers, so fertilizers need to be replenished midway during the operation. Since the quantity of fertilizers is large and the quality is heavy, for example, a bag of chemical fertilizer weighs 100 catties, it is laborious to pour fertilizers upward manually. In the prior art, there are various devices that can lift and feed fertilizers, such as screw conveying, chain lifting, rail lifting, etc. However, screw conveying requires at least two people to operate, and the screw conveying equipment needs to be carried separately and is not suitable for integration on the fertilizer spreading equipment, and the screw conveying efficiency is not very high; there are various forms of chain lifting equipment and rail lifting equipment, which are often used in garbage collection vehicles and can achieve lifting and dumping at the same time. For example, the patent number "202011628672.9" discloses a material lifting device that can automatically turn over materials.

[0003] During the fertilizer spreading operation, feeding is intermittent, and only one person is required to operate the tractor in front during the operation of the fertilizer spreader. Therefore, the ideal feeding mechanism of the existing fertilizer spreading device should only require one person to complete the operation independently. At the same time, to improve efficiency and load more organic fertilizers, the fertilizer tank of the fertilizer spreader is higher, which is difficult and labor-consuming for farmers who load fertilizers manually. Secondly, since the fertilizer spreading mechanism is located at the rear of the fertilizer spreading machinery and needs to be connected to the tractor in the front, the feeding mechanism can only be installed on the side of the fertilizer spreader, which requires reducing its volume and mass as much as possible to avoid excessively increasing the width and the mass on one side of the fertilizer spreader. Moreover, different from garbage collection vehicles, the fertilizer tank of the fertilizer spreader is generally V-shaped, with a large upper end and a small lower end. If the existing lifting and turning device is used, brackets need to be installed separately on the frame and the side of the fertilizer tank. For the above reasons, it is necessary to design a fertilizer spreader feeding device that is applicable to the fertilizer spreader and can be operated by one person alone. Summary of the Invention

[0004] To solve the deficiencies in the prior art, the present invention provides a fertilizer spreading device with simple feeding and better fertilizer spreading effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions: A multi-scenario compatible fertilizer spreader with a feeding mechanism: including a frame, a feeding mechanism, and a fertilizer storage tank arranged above the frame, and the feeding mechanism is used to lift and pour fertilizers into the fertilizer storage tank; The feeding mechanism includes a tipping push rod, a lifting push rod, and a first connecting rod, a second connecting rod, a third hinge member, and a fourth hinge member that are sequentially hinged end to end. The lower ends of the tipping push rod and the lifting push rod are both hinged to the vehicle frame or the fertilizer storage tank. The second connecting rod and the third hinge member are both hinged to the upper fixed hinge point, and the upper fixed hinge point is fixedly connected to the vehicle frame or the fertilizer storage tank; wherein the upper end of the tipping push rod is hinged to the hinge point of the first connecting rod and the second connecting rod, and the upper end of the lifting push rod is hinged to the middle part of the third hinge member; The fourth hinge member is connected to a fertilizer tank hanging bracket for hanging the fertilizer transport tank.

[0006] In order to better achieve tipping, the hinge hole distances at both ends of the second connecting rod are equal to the hinge hole distances at both ends of the fourth hinge member, and the hinge hole distances at both ends of the first connecting rod are equal to the hinge hole distances at both ends of the third hinge member.

[0007] Specifically, the fertilizer tank hanging bracket is parallel to the fourth hinge member and the second connecting rod. When the feeding mechanism is in the state of waiting for loading and the lifting state, the fertilizer tank hanging bracket, the fourth hinge member, and the second connecting rod are all in the vertical state. When the feeding mechanism is in the tipping state, the tipping push rod and the lifting push rod are both in the extended state.

[0008] In order to facilitate the hanging of the fertilizer transport tank, an upper cross beam is provided at the upper end of the fertilizer transport tank hanging bracket, and a claw for connecting with the fertilizer transport tank is provided at the upper end of the upper cross beam. A lower guard plate for abutting against the fertilizer transport tank is also provided below the fertilizer tank hanging bracket.

[0009] In order to ensure that the discharge port of the fertilizer transport tank can extend into the interior of the fertilizer storage tank: the middle part of the third hinge member is bent towards the direction of the first connecting rod. When the feeding mechanism is in the tipping state, the upper end of the fertilizer tank hanging bracket extends into the interior of the upper edge of the fertilizer storage tank.

[0010] Furthermore, a feeding mechanism is provided at the bottom of the fertilizer storage tank, and a fertilizer spreading disc is provided behind the feeding mechanism. The fertilizer spreading disc is provided with at least three main blades. A rib is provided on the upper edge of the main blade, and a secondary blade is provided below the rib. The rib and the secondary blade are both arranged on one side of the rotation direction of the main blade.

[0011] In order to control the spreading width: the angle of the secondary blade relative to the fertilizer spreading disc is adjustable, and the angle of the main blade along the circumferential direction of the fertilizer spreading disc relative to the diameter direction of the fertilizer spreading disc is adjustable.

[0012] Furthermore, a guard plate is provided on the outer edge of the fertilizer spreading disc. The guard plate includes a fixed guard plate and a telescopic guard plate that can be telescopic relative to the fixed guard plate. The telescopic direction of the telescopic guard plate is along the outer edge of the fertilizer spreading disc.

[0013] The vehicle frame is also provided with a transfer case connected to the power output end of the hitch machinery. The transfer case is provided with an oil pump and drives the fertilizer spreading disc to rotate through a transmission shaft. The feeding mechanism is driven by a hydraulic motor, and the hydraulic motor is driven to rotate hydraulically by the oil pump.

[0014] Advantages achieved by the present invention: The present invention has the following advantages. First, during the feeding process, only one person is required to easily complete the operation. When loading, the feeding device completes the main lifting movement, which consumes physical strength. The person mainly completes the work of horizontally shoveling organic fertilizer, which relatively does not consume much physical strength. Second, the entire feeding mechanism is small in size and does not significantly increase the lateral width of the vehicle body. Third, the structure is relatively simple and not prone to failure, and it can be used in a high-dust environment.

[0015] The angles of the main blades and the secondary blades of the present invention can both be adjusted, and can be adjusted to different spreading widths and spreading forms according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0017] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and should not be used to limit the protection scope of the present invention.

[0018] As Figures 1 to 5 shown: This embodiment discloses a multi-scenario compatible fertilizer spreader with a feeding mechanism: including a vehicle frame 1, a feeding mechanism 4, and a fertilizer storage box 2 arranged above the vehicle frame. The feeding mechanism 4 is used to lift and pour fertilizers into the fertilizer storage box 2. The feeding mechanism 4 includes a material turning push rod 41, a lifting push rod 42, and connecting rod one 43, connecting rod two 44, hinge part three 46, and hinge part four 47 that are hinged in sequence from head to tail. The lower ends of the material turning push rod 41 and the lifting push rod 42 are both hinged to the vehicle frame 1 or the fertilizer storage box 2. In practical applications, the lower ends of the material turning push rod 41 and the lifting push rod 42 are preferably hinged to the vehicle frame 1. Connecting rod two 44 and hinge part three 46 are both hinged to the upper fixed hinge point 45, and the upper fixed hinge point 45 is fixedly connected to the vehicle frame 1 or the fertilizer storage box 2. The upper fixed hinge point 45 is preferably fixedly connected to the fertilizer storage box 2. The cross-section of the fertilizer storage box 2 is V-shaped, with a large upper opening and a small lower opening. The material turning push rod 41 and the lifting push rod 42 in this embodiment are preferably hydraulic cylinders.

[0019] The upper end of the material turning push rod 41 is hinged to the hinge point of connecting rod one 43 and connecting rod two 44, and the upper end of the lifting push rod 42 is hinged to the middle part of hinge part three 46.

[0020] Hinge part four 47 is connected to the fertilizer box hitch 3 for hitching the fertilizer transport box. The upper end of the fertilizer box hitch 3 is provided with an upper cross beam 31, and the upper end of the upper cross beam 31 is provided with claws 311 for connecting with the fertilizer transport box 8. The claws 311 are conical, facilitating insertion into the bottom of the upper flange of the fertilizer transport box 8 for hitching with the fertilizer transport box 8. A lower guard plate 32 for abutting against the fertilizer transport box 8 is also provided below the fertilizer box hitch 3.

[0021] Among them, the first connecting rod 43, the second connecting rod 44, the third hinge 46, and the fourth hinge 47 can form a parallelogram, that is: the hinge hole distances at both ends of the second connecting rod 44 are equal to the hinge hole distances at both ends of the fourth hinge 47, and the hinge hole distances at both ends of the first connecting rod 43 are equal to the hinge hole distances at both ends of the third hinge 46. Refer to Figure 4 and Figure 9 , CDEF in the figure is a parallelogram.

[0022] For the convenience of description, the feeding mechanism 4 in this embodiment is divided into three states, namely the waiting-for-loading state ( Figure 1 , Figure 2 and Figure 7 state), the lifting state ( Figure 4 and Figure 8 ), and the tipping state ( Figure 5 and Figure 9 ). In actual use, the three states also occur in sequence according to the time order.

[0023] Therefore, the fertilizer tank hanging bracket 3 is parallel to the fourth hinge 47 and the second connecting rod 44. When the feeding mechanism 4 is in the waiting-for-loading state and the lifting state, the fertilizer tank hanging bracket 3, the fourth hinge 47, and the second connecting rod 44 are all in the vertical state, ensuring that the fertilizer transport tank can be lifted in the vertical state. When the feeding mechanism 4 is in the tipping state, the tipping push rod 41 and the lifting push rod 42 are both in the extended state.

[0024] In order to ensure that after the fertilizer transport tank 8 is lifted, its upper edge can be tilted into the interior of the fertilizer storage tank, the middle part of the third hinge 46 bends towards the first connecting rod 43. The advantage of this is that: this bending part can match the upper edge of the fertilizer storage tank. When the feeding mechanism 4 is in the tipping state, the upper end of the fertilizer tank hanging bracket 3 extends into the interior of the upper edge of the fertilizer storage tank 2.

[0025] Combined with Figure 2 and Figure 6: A feeding mechanism 6 is also provided at the bottom of the fertilizer storage box 2, and a fertilizer spreading plate 5 is provided behind the feeding mechanism 6. The fertilizer spreading plate 5 is usually in a state where the center is high and the outer edge is low. The fertilizer spreading plate 5 is provided with at least three main blades 51. A baffle 511 is provided along the upper edge of the main blade 51, and a secondary blade 512 is provided below the baffle 511. Both the baffle 511 and the secondary blade 512 are arranged on one side of the rotation direction of the main blade 51, that is, the side where the main blade 51 drives the fertilizer. There are usually three secondary blades 512, which are used to guide the centrifugally thrown fertilizer. The angle of the secondary blade 512 relative to the fertilizer spreading plate 5 is adjustable. One end of the secondary blade 512 away from the center of the fertilizer spreading plate 5 is connected to the main blade 51 by screws or rivets, and this connection point is used as a hinge point. There is a fan-shaped through hole 513 on the side of the main blade 51 close to the rotation center. The other end of the secondary blade 512 is connected to the fan-shaped through hole 513, and the angle adjustment of the secondary blade 512 relative to the fertilizer spreading plate 5 is realized by the sliding of the connecting screw inside the fan-shaped through hole 513. The distance between adjacent secondary blades 512 increases in turn from the center to the outer edge of the fertilizer spreading plate 5. The advantage of this is to improve the evenness and coverage area of fertilizer spreading by guiding the fertilizer through the secondary blades 512. As Figure 11 shown: The feeding mechanism 6 includes a chain 61, a bottom plate 62 and a scraper 63. Among them, the bottom plate 62 is located between two parallel chains 61, and the scraper 63 is installed on the two chains. The chain 61 drives the scraper 63 to move relative to the bottom plate 62, and the bottom plate 62 is located at the bottom of the fertilizer storage box 2. The fertilizer poured into the fertilizer storage box 2 falls on the upper surface of the bottom plate 62, and the chain 61 drives the scraper 63 to scrape the fertilizer to the working range of the fertilizer spreading plate 5.

[0026] Furthermore, the angle of the main blade 51 along the circumferential direction of the fertilizer spreading plate 5 relative to the diameter direction of the fertilizer spreading plate 5 is adjustable. Specifically, as Figure 6 shown, there are multiple groups of main blade mounting holes 52 on the fertilizer spreading plate 5, and the angles at which the multiple groups of main blade mounting holes 52 are distributed along the direction of the fertilizer spreading plate 5 are different. Figure 6 The line Q in Figure 6 represents the diameter direction of the fertilizer spreading plate 5, Figure 12 and the angle P in

[0027] represents the angle of the main blade 51 relative to the diameter direction of the fertilizer spreading plate 5 in the plane where the fertilizer spreading plate 5 is located. The main blade 51 can adjust the angle of the main blade 51 relative to the diameter direction of the fertilizer spreading plate 5 by being installed in different positions of the main blade mounting holes 52. The purpose of such adjustment is to control the throwing range of the fertilizer in cooperation with the rotation speed of the fertilizer spreading plate 5.

[0027] In this embodiment, there are two fertilizer spreading plates 5, and the two fertilizer spreading plates 5 are arranged side by side on both sides of the discharge port of the feeding mechanism 6. The rotation directions of the two fertilizer spreading plates 5 are opposite, and the rotation directions can be referred to the thick arrows in Figure 6 , that is to say, the fertilizer is thrown outwards from the middle direction of the two fertilizer spreading plates 5.

[0028] As can be seen from the above description, the angles of both the main blade 51 and the secondary blade 512 are adjustable. When the two blades are used in combination, the spreading width of the fertilizer can be controlled. Figure 2 In [reference], the P1 and P2 regions respectively represent the spreading ranges of the two fertilizer spreading discs 5. The angle of the secondary blade 512 determines the elevation angle of the fertilizer relative to the horizontal plane when it leaves the fertilizer spreading disc 5. Adjusting an appropriate elevation angle can increase the area of fertilizer distribution on the ground. The angle of the main blade 51 determines the initial velocity direction of the fertilizer when it leaves the fertilizer spreading disc 5. As Figure 6 shown, within a certain range, Figure 6 when the angle P in [reference] decreases, the rotation angle of the fertilizer from entering the working area of the fertilizer spreading disc 5 to leaving the fertilizer spreading disc 5 is relatively large. Conversely, Figure 6 when the angle P in [reference] increases, the rotation angle of the fertilizer from entering the working area of the fertilizer spreading disc 5 to leaving the fertilizer spreading disc 5 is relatively small. By adjusting the angle of the main blade 51 and the rotation speed of the fertilizer spreading disc 5, the spreading width of the fertilizer can be effectively controlled. Further coordinating with the angle of the secondary blade 512 can further improve the uniformity. Moreover, the spreading widths (P1 and P2 regions) corresponding to the two main blades 51 can also be adjusted separately to adapt to the situation of sweeping one side of the farmland.

[0029] As Figure 10 shown: The power system of this embodiment is as follows. The vehicle frame 1 is also provided with a transfer case 11 connected to the power output end of the hitch machinery. The transfer case 11 is provided with an oil pump 12 and drives the fertilizer spreading disc 5 to rotate through a transmission shaft 7. The feeding mechanism 6 is driven by a hydraulic motor 9, and the hydraulic motor 9 is driven to rotate hydraulically by the oil pump 12. At the same time, the oil pump 12 can also drive the material turning push rod 41 and the lifting push rod 42 to do telescopic movements. The specific control device and principle belong to the prior art and will not be elaborated in this embodiment.

[0030] Combined with Figures 7 to 9 shown: When the fertilizer spreader is in the normal fertilizer spreading state, the feeding mechanism 4 retracts under the side of the fertilizer storage tank 2. Since the cross-section of the fertilizer storage tank 2 is in a V-shaped structure, the feeding mechanism 4 hardly increases the width of the fertilizer spreader, and the fertilizer tank hitch frame 3 is also in a vertical state, so the increase in the vehicle width is relatively small, usually controlled within about 10 cm.

[0031] When it is necessary to replenish fertilizer into the fertilizer storage tank 2, only need to move the fertilizer transport tank 8 to the side of the fertilizer tank hitch frame 3 and insert the claw 311 into the bottom of the upper flange of the fertilizer transport tank 8. By controlling the extension of the lifting push rod 42, the fertilizer tank hitch frame 3 can move upward in a vertical state. When the fertilizer transport tank 8 moves to a certain height above the upper edge of the fertilizer storage tank 2, that is Figure 8In the state, then operate the turnover push rod 41 to extend, driving the above-mentioned parallelogram CDEF to move. During this process, point F rotates upward with point C as the center to a height higher than point C, so that the fertilizer inside the fertilizer transport box 8 can be poured into the fertilizer storage box 2.

[0032] As Figure 11 and Figure 12 shown: Two fertilizer spreading discs 5 are arranged side by side on both sides of the discharge port of the feeding mechanism 6; a guard plate is also provided on the outer edge of the fertilizer spreading disc 5. The function of the guard plate is to prevent the fertilizer from spilling outside the fertilizer spreading disc 5 and can play a certain guiding role for the fertilizer. Among them, the guard plate includes a fixed guard plate 53 and a telescopic guard plate 54 that can be telescopic relative to the fixed guard plate 53. The telescopic direction of the telescopic guard plate 54 is along the outer edge of the fertilizer spreading disc 5. The telescopic guard plate 54 can rotate relative to the fixed guard plate 53 to adjust the fertilizer outlet and the spreading range. Figure 13 and Figure 14 is an example of adjusting the spreading width and spreading range by controlling different opening sizes of the telescopic guard plate 54. In practical applications, the fully open state of the guard plate is suitable for normal operations in large fields. Closing part of the guard plate can reduce the centrifugal fertilizer spreading disc to be converted into a side-spreading fertilizer spreading disc. By adjusting the rotation speed, band application ( Figure 14 ) or side spreading can be achieved. This mode is suitable for orchards and protected agriculture.

[0033] Compared with the prior art, this embodiment has the following advantages: First, only one person can easily complete the operation during the feeding process. During loading, the feeding device completes the main lifting movement, and the person mainly completes the work of horizontally shoveling organic fertilizer (relatively less labor-consuming). Second, the entire feeding mechanism 4 is small in size and does not significantly increase the lateral width of the vehicle body. Third, the structure is relatively simple and not prone to failure, and it can be used in a high-dust environment.

[0034] The angles of the main blades 51 and the secondary blades 512 of the present invention can both be adjusted, and can be adjusted to different spreading widths and spreading forms according to actual needs.

[0035] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
