Description

Technical Field

[0001] The utility model belongs to the field of sowing fertilizer boxes, and particularly relates to a novel sowing fertilizer box. Background Art

[0002] With the continuous improvement of the degree of agricultural mechanization, mechanical equipment has gradually replaced traditional manual planting. The seeder used in conjunction with a tractor can complete multiple operations such as tillage, fertilization, sowing, soil covering, and compaction at one time, greatly improving the planting efficiency. To complete fertilization, the seeder needs to place the fertilizer in the fertilizer box. Most of the existing fertilizer boxes have the following problems: First, the bottom is wide, and during the operation and vibration of the seeder, the fertilizer settles and accumulates, and when discharging fertilizer, it cannot smoothly enter the fertilizer box, and then from the fertilizer box to the furrow opener and into the soil. Second, the installation position of the fertilizer box is fixed and cannot be adjusted according to different row spacings, with low flexibility.

[0003] Moreover, most of the existing fertilizer boxes control the fertilizer discharge amount through mechanical transmission. Limited by the mechanical structure, sometimes there will be problems such as untimely or stagnant sprocket transmission, resulting in uneven fertilizer discharge or even no fertilizer discharge, greatly affecting the quality and efficiency of sowing.

[0024] Embodiment:

[0025] A new type of sowing fertilizer box, as Figure 5 shown, includes a fertilizer box body 1 and a fertilizer discharging mechanism 9. The fertilizer box body 1 is provided with a fertilizer adding cavity 11 and a fertilizer discharging cavity 12. As Figure 3 shown, the fertilizer adding cavity 11 and the fertilizer discharging cavity 12 are distributed up and down and communicate with each other; the opening of the fertilizer adding cavity 11 serves as the overall fertilizer adding port, and fertilizers are added into the entire cavity from the fertilizer adding port. In order to prevent fertilizers from spilling during work, a fertilizer box cover is provided on the outer wall of the fertilizer box body 1. The fertilizer box cover covers the opening of the fertilizer adding cavity 11. In this embodiment, the fertilizer box cover is made of flexible materials as a whole, such as cloth; one end is fixed to the top of the fertilizer box body 1 with a pressure strip, and the other end is buckled to a hook 8 with a rubber pull handle. The hook 8 is arranged on the fertilizer box body 1. And telescopic ropes are also arranged on both sides of the fertilizer box cover, which can enable the fertilizer box cover to completely cover the fertilizer adding cavity, avoiding the spilling of fertilizers due to the bumping and vibration of the sowing wheels or external forces, damaging the working environment and affecting the working efficiency.

[0026] Both side walls of the fertilizer discharging cavity 12 along the traveling direction are inclined wall plates 121. As Figures 1-5 shown, the two side walls adjacent to the inclined wall plates can be straight plates or inclined inward; several guide plates 3 are detachably arranged in the fertilizer discharging cavity 12. The guide plates 3 divide the fertilizer discharging cavity 12 into several fertilizer discharging sub-cavities. The guide plates are inclined towards the fertilizer discharging sub-cavities. The tops of the guide plates of adjacent two fertilizer discharging sub-cavities abut against each other, presenting an overall triangular pyramid shape. And in order to provide support force for the guide plates, cross braces are arranged in the fertilizer discharging cavity. The tops of the guide plates are restricted and supported by the cross braces, and the lower parts of the guide plates abut against the two inclined wall plates. The guide plates are designed as single-body structures and can be removed separately when the motor is installed or repaired. During sowing operations, they are placed on the support frames, playing the roles of fertilizer separation and fertilizer guiding.

[0027] Several fertilizer discharging ports are provided on the inclined wall plates 121 where the fertilizer discharging mechanism 9 is installed. The fertilizer discharging ports correspond to the fertilizer discharging sub-cavities one by one; a fertilizer cleaning port 4 is provided on the other inclined wall plate; an insertion plate is arranged at the fertilizer cleaning port. Usually, during fertilizer adding or operation, the insertion plate blocks it, making the fertilizer cleaning port in a closed state. If maintenance or emergency discharging is required, the insertion plate can be pulled up at any time to achieve the purpose of discharging materials. This structure is both safe and reliable and time-saving and labor-saving.

[0028] In order to prevent sundries from entering the fertilizer discharging cavity 12, a detachable filter screen is provided in the fertilizer adding cavity 11 above the material guiding plate 3. And the detachable protective filter screen includes at least two protective filter screens 7, and a support between the filter screens is provided in the fertilizer discharging cavity 12. The support between the filter screens is clamped between two inclined wall plates of the fertilizer discharging cavity, providing a placement position for the protective filter screen. After the protective filter screen is placed, its side contacts and is supported by the inner wall of the fertilizer tank body and the top of the support between the filter screens; it can be freely disassembled and taken as needed; and for quick disassembly, a handle can be installed on the protective filter screen. The detachable protective filter screen can isolate sundries such as stones, films, and plastic papers during operation to prevent them from entering the fertilizer tank, avoiding blockage of the fertilizer tank, and the segmented protective filter screen makes the individual protective filter screen more rigid, and it is very convenient and fast to place or take out.

[0029] In order to facilitate observing the fertilizer situation, a transparent observation window 10 is provided on the upper part of the fertilizer tank body 1, which is convenient for the driver and user to check the fertilizer usage at any time.

[0030] The fertilizer tank body is installed on the seeder by relying on the fertilizer tank support structure installed on the fertilizer tank body 1. The fertilizer tank support structure includes two fertilizer tank support components, namely the first fertilizer tank support component and the second fertilizer tank support component.

[0031] As Figures 1-3 and Figure 5 shown, the first fertilizer tank support component includes two first fertilizer tank supports 21 and a first support base 22. The first support base 22 is fixed in the length direction of the inclined wall plate 121, and a plurality of second fixing holes 1211 are arranged on both the upper and lower sides of the first support base 22. The upper and lower two second fixing holes are a group, providing an installation position for the first fertilizer tank support 21. The two first fertilizer tank supports 21 are parallel and spaced apart, and each first fertilizer tank support 21 is provided with a first fixing hole 211 at the end corresponding to the inclined wall plate; the first fertilizer tank support 21 abuts against the first support base 22, and a locking pin passes through the first fixing hole 211 and the corresponding second fixing hole 1211 to fix the first fertilizer tank support 21 on the first support base 22. And the inner side of the locking pin passes through the inclined wall plate, and the extra part can support and limit the protective filter screen. In this embodiment, the first support base is made of a square tube, and the square tube is welded to the inclined wall plate. The first fertilizer tank support can abut against different positions of the first support base, so as to change the distance between the two first fertilizer tank supports to meet the requirements of different crop spacings.

[0032] The second fertilizer tank support assembly includes a second support base body 23, a second fertilizer tank support 24, and a fertilizer tank fixing base plate 25. The fertilizer tank fixing base plate 25 is detachably mounted on the outer wall of the fertilizer tank body 1 by bolts. The fertilizer tank fixing base plate 25 is provided with an extended fixing portion 251 and an extended external fixing portion 252. The extended fixing portion 251 is away from the inclined wall plate, and the extended fixing portion 251 is provided with an extended fixing hole. The extended external fixing portion 252 is flush with the end face of the inclined wall plate where the first support base body is located. And the extended external fixing portion 252 is provided with second fixing holes 1211 on both sides of the first support base body. The axes of the second fixing holes 1211 coincide with the axis of the extended fixing hole.

[0033] The second support base body 23 is welded to the fertilizer tank fixing base plate 25. In this embodiment, it is welded to the extended fixing portion 251. Since there is a spacing between the second support base body 23 and the inclined wall plate, the second support base body 23 between the two fertilizer tank fixing base plates can all be used as the adjustment and installation position of the second fertilizer tank support. After the second fertilizer tank support 24 abuts against the second support base body, it can be directly fixed with bolts to fix the second fertilizer tank support 24 on the second support base body. Corresponding to the change of different fixing positions of the first fertilizer tank support on the inclined wall plate, it meets the fertilization requirements of different row spacings.

[0034] And in order to provide the maximum row spacing, the extended fixing portion and the extended external fixing portion provide the installation positions corresponding to the maximum row spacing for the second fertilizer tank support and the first fertilizer tank support. The first fertilizer tank support realizes the change of the spacing by adjusting different installation positions on the inclined wall plate, while the second fertilizer tank support realizes the adjustment of the spacing by changing the installation position on the second support base body. The positional relationship between the two fertilizer tank supports is adjusted synchronously. And the fertilizer tank fixing base plate connects the first fertilizer tank support assembly and the second fertilizer tank support assembly together, improving the connection strength with the seeder.

[0035] In order to intuitively know the inclination degree of the fertilizer tank, a leveling pointer structure is provided on the fertilizer tank body 1. The leveling pointer structure includes a leveling pointer 5 and an angle scale 6. The angle scale 6 is horizontally fixed on the side wall of the fertilizer tank body 1. The upper end of the leveling pointer 5 is hinged on the fertilizer tank body 1, and the tip of the leveling pointer 5 points to the angle scale 6. The leveling pointer always remains in a vertical state. When the fertilizer tank body is tilted, since the leveling pointer is still vertically downward, the scale pointing to the angle scale will show the tilt angle. In the normal state, the leveling pointer points to the zero degree of the angle scale, and the stable state of the whole machine can be checked at any time. If it is found that the tilt angle of the fertilizer tank body is too large or other abnormal situations, adjustments can be made in time to avoid affecting the sowing effect.

[0036] The fertilizer discharging mechanism 9 used includes a fertilizer discharging motor 91, a fertilizer discharging shaft 92, several fertilizer discharging boxes 93, a fertilizer discharging mounting base plate 94, a travel speed sensor, and a controller; the fertilizer discharging mounting base plate 94 adopts a single-plate sheet metal structure to be installed on the inclined wall plate 121, providing support for the fertilizer discharging motor and the fertilizer discharging box and the fertilizer discharging shaft, which can reduce the unilateral stress of the side plate of the fertilizer box body and improve the safety of the box body. A clearance hole is provided at the position corresponding to the fertilizer discharging opening of the fertilizer discharging mounting base plate 94; a fertilizer discharging box 93 is installed at each fertilizer discharging opening, and the feed port of the fertilizer discharging box 93 is communicated with the fertilizer discharging opening; the fertilizer discharging motor 91 is installed at the discharging opening. The fertilizer is mounted on the base plate 24, and the fertilizer motor 91 is a dual-output motor. Both output ends of the fertilizer motor 91 are connected to a fertilizer shaft 92 in a transmission manner. Each fertilizer shaft 92 runs through its own fertilizer box 93 and drives the groove wheel in the fertilizer box to rotate. Moreover, the transmission structure between the fertilizer motor, the fertilizer shaft and the fertilizer box adopts CN218603982, a transmission method in the structure of an electric fertilizer transmission device. The travel speed sensor is installed on the planter or the fertilizer box body to detect the travel speed of the planter relative to the ground. The controller controls the speed of the fertilizer motor according to the travel speed. The fertilizer motor is a dual-output motor that uses two sections of fertilizer shafts to drive the corresponding fertilizer box. The fertilizer shaft is coaxial with the output shaft of the fertilizer motor. Compared with the through shaft, the overall stability is better, which avoids the distortion of the through shaft caused by the blockage of a fertilizer box, thereby causing the fertilizer to be discharged asynchronously and affecting the fertilization effect.
