Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crop planting equipment, in particular to a fertilizing assembly. Background Art
[0002] The fertilizer assembly is an important component of sowing machinery such as soybean planters and corn planters. It is mainly used to apply fertilizer during sowing, eliminating the need for manual fertilization, improving the degree of mechanization in crop planting and making crop planting more convenient.
[0003] In the prior art, the fertilization assembly mainly includes a furrowing disc, a fertilization pipe is located on one side of the furrowing disc and is in a fixed state, the furrowing disc is installed on the frame of the seeder through an adjusting arm and a mounting seat, and a contouring mechanism is also installed between the furrowing disc and the adjusting arm.
[0004] In the above-mentioned prior art, the adjustment of the upper and lower positions of the furrowing disc is often fine-tuned by adjusting the tension of the shock-absorbing spring in the profiling mechanism. The adjustable range is small. When it is transferred to a seed drill with a higher or lower frame, it cannot be used and has poor applicability. Utility Model Content
[0005] In view of the above problems, the present invention provides a fertilizing assembly to solve the problem in the prior art that the adjustment range of the upper and lower positions of the furrowing disc is small and the applicability is poor.
[0006] The utility model is implemented using the following technical solutions: a fertilizing assembly, comprising a mounting seat, an adjusting arm slidably mounted on the middle part of the mounting seat, a profiling mechanism mounted on one end of the adjusting arm away from the mounting seat, a ditching disc rotatably mounted on one end of the profiling mechanism away from the adjusting arm, a fertilizing pipe mounted on one side of the ditching disc; a limiting mechanism for preventing relative sliding between the adjusting arm and the mounting seat is also mounted between the adjusting arm and the mounting seat, and a locking mechanism for starting or closing the limiting mechanism is also mounted on the mounting seat.
[0007] Through the above structure, the operator can cancel the effect of the limiting mechanism through the locking mechanism, so that the adjusting arm can be adjusted up and down, thereby enabling the furrowing disc to be adjusted up and down to meet the requirements of different fertilization depths and different seed drill frame heights, thereby increasing the applicability of the device.
[0008] Furthermore, the limiting mechanism includes a plurality of first limiting teeth fixedly mounted on the adjustment arm, a second limiting tooth fixedly mounted on the inner side of the mounting seat, and the locking mechanism can make the first limiting teeth engage or disengage with the second limiting teeth. When the first limiting teeth are engaged with the second limiting teeth, the mounting seat and the adjustment arm are relatively fixed; when the first limiting teeth are separated from the second limiting teeth, the mounting seat and the adjustment arm can slide relative to each other. Through the above structure, when the first limiting teeth are engaged with the second limiting teeth, the adjustment arm is prevented from moving up and down when fixed. When adjustment is required, the adjustment arm only needs to be moved in a direction away from the second limiting teeth to disengage the first limiting teeth and the second limiting teeth, thereby adjusting the upper and lower positions of the adjustment arm.
[0009] Furthermore, the locking mechanism includes an adjusting bolt mounted on a side of the mounting base away from the second limiting tooth. The adjusting bolt is capable of abutting against the adjusting arm and is threadedly engaged with the mounting base. The adjusting bolt is used to control the adjusting arm's proximity to or distance from the second limiting tooth, making the locking mechanism simpler in structure and more convenient to operate.
[0010] Furthermore, the contouring mechanism includes a trenching arm hinged to the adjustment arm, the trenching arm being rotatably connected to the trenching disc, a connecting plate hinged to one end of the trenching arm remote from the adjustment arm, a shock-absorbing spring hinged to one end of the connecting plate remote from the trenching arm, and a shock-absorbing spring hinged to the adjustment arm at one end remote from the connecting plate. The adjustment arm, trenching arm, connecting plate, and shock-absorbing spring form a quadrilateral. The configuration of the contouring mechanism enables the device to better respond to changes in terrain during fertilization.
[0011] Furthermore, a first scraper is fixedly mounted on the connecting plate, and the first scraper is in contact with the ditching disc. By setting the first scraper, the mud on the ditching disc can be cleaned in time to prevent affecting the subsequent ditching.
[0012] Furthermore, a second scraper is fixedly mounted on the ditching support arm, and the second scraper is in contact with the ditching disc. The second scraper can further clean the mud on the ditching disc.
[0013] Furthermore, the mounting base is provided with fixing bolts in the form of "U"-shaped bolts, which are located on both sides of the mounting base, with both ends of the fixing bolts passing through the mounting base. The provision of "U"-shaped fixing bolts makes it easier to adjust the device in the lateral direction, without having to drill holes in the frame for fixing.
[0014] Furthermore, the limiting mechanism includes a first limiting block fixedly mounted on both sides of one end of the adjustment arm near the mounting seat, and two second limiting blocks slidably mounted in the mounting seat, the second limiting blocks being able to be plugged into the first limiting block under the action of a locking mechanism, and when the first limiting block and the second limiting block are plugged into each other, the adjustment arm and the mounting seat are relatively fixed, and when the first limiting block and the second limiting block are disengaged, the adjustment arm can slide relative to the mounting seat. By plugging in or out of the first limiting block and the second limiting block, the mounting seat and the adjustment arm can be directly fixed or moved relative to each other.
[0015] Furthermore, the locking mechanism includes a mounting plate fixedly mounted on the middle portion of the mounting seat, the mounting plate slidingly engaging with the adjustment arm, return springs fixedly mounted on both sides of the mounting plate, the end of the return spring away from the mounting plate being fixedly connected to a second limit block, an extrusion block fixedly mounted on the second limit block, sliding holes formed on both sides of the mounting seat, the extrusion block slidingly engaging with the sliding holes, and the end of the extrusion block away from the mounting plate being able to slide to the outside of the mounting plate. By providing the extrusion block, when the adjustment arm needs to be moved up and down, it can be achieved by simply pressing the extrusion block. When the position is adjusted, the extrusion block is released, and under the action of the return spring, the second limit block will be re-inserted into the first limit block, making it more convenient to use.
[0016] Furthermore, fixing plates are fixedly mounted on both sides of the mounting plate, with one end of the fixing plate away from the mounting plate being fixedly connected to the mounting seat, and the fixing plates pass through the second limiting block and slidably engage with the second limiting block. The sliding engagement between the fixing plates and the second limiting block makes the second limiting block more stable when sliding.
[0017] In summary, the beneficial effects of the present invention are:
[0018] 1. The locking mechanism cancels the function of the limit mechanism, so that the adjusting arm can be moved, so that the furrowing disc can be adjusted up and down to meet the requirements of different fertilization depths and different seed drill frame heights, thereby increasing the applicability of the device.
[0019] 2. Through the setting of the independent profiling mechanism, the ditching disc can change up and down with the undulation of the terrain when ditching, so that the depth of the ditch remains consistent, improving the quality of fertilization, and the profiling mechanism will also make the structure of the device more stable and increase the service life of the device.

[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings. Example 1
[0030] like Figures 1 to 3As shown, the utility model provides a fertilizer assembly, including a mounting base 12. The two sides of the top of the mounting base 12 extend outward, forming a "T"-shaped structure. Fixing bolts 11 capable of being fixed to the frame 10 are installed at the extensions on both sides of the mounting base 12. An adjustment arm 7 is slidably mounted in the middle of the mounting base 12. A profiling mechanism is mounted on the end of the adjustment arm 7 away from the mounting base 12. A trenching disc 2 is rotatably mounted on the end of the profiling mechanism away from the adjustment arm 7. A fertilizer pipe 1 connected to the fertilizer box is mounted on one side of the trenching disc 2. The position of the fertilizer pipe 1 is fixed. During the trenching and fertilizing process, the trenching disc 2 rotates relative to the fertilizer pipe 1. A limiting mechanism is also installed between the adjusting arm 7 and the mounting base 12 to prevent the two from sliding relative to each other. A locking mechanism is also installed on the mounting base 12 to activate or deactivate the limiting mechanism.
[0031] The limiting mechanism includes a plurality of first limiting teeth 9 fixedly mounted on the side of the adjusting arm 7 near the ditching disc 2, and a second limiting tooth 13 fixedly mounted on the inner side of the mounting seat 12. The locking mechanism can make the first limiting teeth 9 engage or disengage with the second limiting teeth 13. When the first limiting teeth 9 and the second limiting teeth 13 are engaged, the mounting seat 12 and the adjusting arm 7 are relatively fixed; when the first limiting teeth 9 and the second limiting teeth 13 are disengaged, the mounting seat 12 and the adjusting arm 7 can be relatively fixed. The number of the first limiting teeth 9 is far greater than the number of the second limiting teeth 13, and the first limiting teeth 9 are mainly located at the end of the adjusting arm 7 near the mounting seat 12.
[0032] The locking mechanism includes an adjusting bolt 14 mounted on a side of the mounting seat 12 away from the second limiting tooth 13 . The adjusting bolt 14 can abut against the adjusting arm 7 , and the adjusting bolt 14 is threadedly engaged with the mounting seat 12 .
[0033] In the initial state, the mounting seat 12 and the adjusting arm 7 are fixed, that is, the first limiting tooth 9 is engaged with the second limiting tooth 13, and there is space for the adjusting arm 7 to move laterally between the side of the adjusting arm 7 away from the first limiting tooth 9 and the side of the mounting seat 12 away from the first limiting tooth 9. When it is necessary to adjust the height of the grooving disc 2, it is necessary to twist the adjusting bolt 14 so that the adjusting bolt 14 no longer presses against the adjusting arm 7, and then disengage the first limiting tooth 9 and the second limiting tooth 13, and then adjust the position of the adjusting arm 7 up and down. When the position is adjusted, twist the adjusting bolt 14 in the opposite direction so that the adjusting bolt 14 presses against the adjusting arm 7 again, so that the first limiting tooth 9 is engaged with the second limiting tooth 13.
[0034] The contouring mechanism includes a trenching arm 5 hinged to an adjustment arm 7, which is rotatably connected to the trenching disc 2. The end of the trenching arm 5 away from the adjustment arm 7 is hinged to a connecting plate 8, and the end of the connecting plate 8 away from the trenching arm 5 is hinged to a shock-absorbing spring 6. The end of the shock-absorbing spring 6 away from the connecting plate 8 is hinged to the adjustment arm 7. The end of the adjustment arm 7 away from the mounting seat 12, the trenching arm 5, the connecting plate 8, and the shock-absorbing spring 6 form a parallelogram. In the contouring mechanism, the vertical position of the trenching disc 2 can be fine-tuned by adjusting the tension of the shock-absorbing spring 6. Adjusting the tension of the shock-absorbing spring 6 is a prior art and will not be described in detail here.
[0035] As a further illustration of this example, a first scraper 3 is fixedly mounted on the connecting plate 8, and a second scraper 4 is fixedly mounted on the trenching arm 5. Both the first scraper 3 and the second scraper 4 are in contact with the trenching disc 2. The first scraper 3 and the second scraper 4 are both used to clean mud from the trenching disc 2 so that it does not affect the subsequent trenching process.
[0036] As a further illustration of this embodiment, the fixing bolt 11 is a "U"-shaped bolt. Both ends of the "U"-shaped fixing bolt 11 pass through the mounting seat 12. The frame 10 passes through the space between the fixing bolt 11 and the mounting seat 12. When the position of the ditching disc 2 needs to be adjusted laterally, only the fixing bolt 11 needs to be loosened, and then the mounting seat 12 can be slid left and right. When the position adjustment is completed, the fixing bolt 11 can be tightened to fix it. This method does not require the redoing of adjustment holes in the frame 10, protects the structure of the frame 10, and is very convenient to operate. Example 2
[0037] like Figures 4 to 6 As shown, the structure of this embodiment is basically the same as that of the first embodiment, and the difference between them mainly lies in the specific structures of the limiting mechanism and the locking mechanism; specifically, the limiting mechanism includes a first limiting block 15 fixedly installed on both sides of one end of the adjusting arm 7 close to the mounting seat 12, and two second limiting blocks 18 are slidably installed in the mounting seat 12, and the second limiting block 18 can be plugged with the first limiting block 15 under the action of the locking mechanism. When the first limiting block 15 and the second limiting block 18 are plugged, the adjusting arm 7 and the mounting seat 12 are relatively fixed. When the first limiting block 15 and the second limiting block 18 are disengaged, the adjusting arm 7 can slide relative to the mounting seat 12.
[0038] The locking mechanism includes a mounting plate 21 fixedly mounted in the middle of the mounting seat 12, the mounting plate 21 slidingly cooperates with the adjusting arm 7, and return springs 20 are fixedly mounted on both sides of the mounting plate 21, and the end of the return spring 20 away from the mounting plate 21 is fixedly connected to the second limit block 18, and an extrusion block 16 is fixedly mounted on the second limit block 18. Sliding holes 17 are provided on both sides of the mounting seat 12, and the extrusion block 16 slides with the sliding holes 17. The end of the extrusion block 16 away from the mounting plate 21 can slide to the outside of the mounting plate 21.
[0039] In the initial state, the second limit block 18 is plugged into the first limit block 15. When it is necessary to adjust the upper and lower positions of the grooving disc 2, it is only necessary to press the extrusion blocks 16 on both sides of the mounting seat 12 so that the second limit block 18 slides inward and disengages from the first limit block 15. At this time, the position of the adjusting arm 7 can be adjusted up and down. When the appropriate position is reached, the extrusion block 16 is released, and the extrusion block 16 rebounds under the action of the return spring 20. The first limit block 15 and the second limit block 18 are re-plugged together, thereby fixing the mounting seat 12 and the adjusting arm 7.
[0040] As a further explanation of this example, in order to make the sliding of the second limit block 18 more stable, fixed plates 19 are fixedly installed on both sides of the mounting plate 21. The end of the fixed plate 19 away from the mounting plate 21 is fixedly connected to the mounting seat 12, and the fixed plate 19 passes through the second limit block 18 and slides with the second limit block 18.
[0041] The operating principle of this device is as follows: when the ditching disc 2 needs to be adjusted up or down, the locking mechanism is simply used to control the disengagement of the limiting mechanism, thereby allowing the adjustment arm 7 to be adjusted up and down. When the adjustment arm 7 is in the appropriate position, the locking mechanism is used to limit the relative movement between the adjustment arm 7 and the mounting base 12, thereby achieving a fixed effect. When the position of the ditching disc 2 needs to be adjusted laterally, the fixing bolt 11 is simply loosened and the mounting base 12 can be adjusted on the frame 10. When it is in the appropriate position, the fixing bolt 11 is re-tightened.
[0042] In summary, the fertilizing assembly provided by the present invention cancels the effect of the limiting mechanism through a locking mechanism, thereby enabling the adjusting arm 7 to move, so that the ditching disc 2 can be adjusted up and down to meet the requirements of different fertilization depths and the heights of different seed drill frames, thereby increasing the applicability of the device; through the setting of an independent profiling mechanism, the ditching disc 2 can change up and down with the undulations of the terrain when ditching, thereby keeping the depth of the ditch consistent, improving the quality of fertilization, and the profiling mechanism will also make the structure of the device more stable, thereby increasing the service life of the device.
[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
