Description

Technical Field

[0001] The invention relates to the technical field of seed drills, in particular to a multi-stage compound suppression seed drill. Background Art

[0002] A compaction seeder is an agricultural planting machine that combines sowing and compaction operations. While completing the sowing task, it can also compact the soil where the seeds are sown. When working, the tractor pulls the seeder forward, and the seeds in the seed box are discharged into the seed delivery tube through the seed meter according to a certain sowing amount, and fall into the opened groove through the furrow opener. Then the compaction roller compacts the soil after sowing, so that the seeds are in close contact with the soil, creating good conditions for seed germination and growth. There are two shapes of compaction rollers, smooth and grooved. The two different shapes of compaction rollers have different and respective usage scenarios. In some specific usage scenarios, if there are many clods in the soil that need to be broken and there is a need to conserve moisture, such as in some mountain fields, the soil texture is not good. If there are large clods and water is easily lost, a grooved pressing roller may be used first to break up the clods, preliminarily level the land and improve the soil structure, and then a smooth pressing roller may be used to further compact the soil to improve the flatness and moisture retention effect. In this scenario, when using different pressing rollers, the pressing roller needs to be replaced. Replacing the pressing roller requires manual operation. The originally installed pressing roller must be removed and another pressing roller must be installed. This process is relatively cumbersome, especially in mountainous fields. Due to the complex terrain and limited operating space for agricultural machinery, replacing the pressing roller is more difficult and will consume a lot of time and energy, increasing the labor intensity of farmers and reducing work efficiency.

Detailed implementation mode

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation mode of the present invention with reference to the accompanying drawings of the specification.

[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation mode of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0030] Embodiment 1 Refer to Figures 1-4 , which is the first embodiment of the present invention. This embodiment provides a multi-stage compound rolling press seeder. The multi-stage compound rolling press seeder includes a seeder 101, which is composed of components such as a frame, a traction or suspension device, a seed box, a seed metering device, a transmission device, a seed tube, and a furrow opener, and can complete seeding operations. A rolling press roller 102 is arranged on one side of the seeder 101. The rolling press roller 102 is used to roll press the soil after seeding, so that the seeds are in close contact with the soil, creating good conditions for seed germination and growth. This is the prior art and will not be elaborated in detail in this solution, and those skilled in the art can clearly understand the working principle.

[0031] The pressing roller 102 is provided with grooves 103. There are multiple grooves 103, which are evenly distributed in a straight line on the pressing roller 102. A first clamping sleeve 104 and a second clamping sleeve 105 are sleeved outside the grooves 103. Both the first clamping sleeve 104 and the second clamping sleeve 105 are semi-circular and correspond to the number of grooves 103.

[0032] When the first clamping sleeve 104 and the second clamping sleeve 105 are clamped outside the grooves 103, the surface of the pressing roller 102 will become a smooth shape at this time. The pressing roller 102 in this state can make the soil surface reach a high flatness, providing a good surface environment for crop growth, especially suitable for crops with high requirements for the surface flatness of the ground.

[0033] If it is necessary to switch the shape of the pressing roller 102 to another state, move the first clamping sleeve 104 and the second clamping sleeve 105 to both sides respectively and separate them from the grooves 103, and then move the first clamping sleeve 104 and the second clamping sleeve 105 upward to above the pressing roller 102, so as not to hinder the normal operation of the pressing roller 102. At this time, the grooves 103 on the surface of the pressing roller 102 are exposed, and the switching of the state of the pressing roller 102 is completed. When the pressing roller 102 in this state rolls, it can break up soil clods. For fields with hard soil texture and many soil clods, it can better improve the soil structure, make the seeds fully contact with the fine soil, and thus the pressing roller 102 can be applied to different operation scenarios without disassembling and replacing the pressing roller 102, thereby saving a lot of time and energy and improving the operation efficiency.

[0034] The switching component 200 is arranged above the pressing roller 102 and includes a clamping member 201. There are multiple groups of clamping members 201, which respectively correspond to the first clamping sleeve 104 and the second clamping sleeve 105.

[0035] The clamping member 201 includes a support frame 2011 fixed to one side of the seeder 101. A movable sleeve 2012 is inserted into the support frame 2011. The movable sleeve 2012 is movably connected inside the support frame 2011. A convex block is fixed at the bottom of the movable sleeve 2012. A support frame 2013 is fixed on one side of the movable sleeve 2012. There are two support frames 2013, which are respectively fixed on both sides of the movable sleeve 2012. A support rod 2014 is inserted into the support frame 2013. The support rod 2014 is L-shaped. An electromagnet 2015 is fixed on one side of the support rod 2014. There are two electromagnets 2015, which are respectively fixed to the two support rods 2014.

[0036] When it is necessary to separate the first ferrule 104 and the second ferrule 105 from the groove 103, the movable sleeve 2012 is moved downward, driving the support frame 2013 and the support rod 2014 downward. When the support rod 2014 moves down to the designated position, the convex block at the bottom of the movable sleeve 2012 will contact the connection between the first ferrule 104 and the second ferrule 105. At this time, the movable sleeve 2012 cannot move downward continuously. At the same time, the two electromagnets 2015 will be located on the sides of the first ferrule 104 and the second ferrule 105. At this time, the two electromagnets 2015 will move centrally and contact the first ferrule 104 and the second ferrule 105 respectively. At this time, the electromagnets 2015 can be energized, so that the magnetic force generated by the electromagnets 2015 attracts the first ferrule 104 and the second ferrule 105. Then, the two will drive the first ferrule 104 and the second ferrule 105 to move outward respectively and separate from the groove 103. After that, the movable sleeve 2012 will drive the support frame 2013 and the support rod 2014 to move upward, and drive the first ferrule 104 and the second ferrule 105 to move upward through the support rod 2014, so that they can move above the pressing roller 102.

[0037] If it is necessary to connect the first ferrule 104 and the second ferrule 105 to the outside of the groove 103, the movable sleeve 2012 is driven to drive the support frame 2013 and the support rod 2014 to move downward, and the first ferrule 104 and the second ferrule 105 are moved downward to the initial position. At this time, the support rod 2014 will drive the first ferrule 104 and the second ferrule 105 to contact the groove 103. Then, the electromagnets 2015 are powered off, so that the first ferrule 104 and the second ferrule 105 can be connected to the outside of the groove 103.

[0038] Embodiment 2 Refer to Figures 5-10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0039] Specifically, the switching component 200 further includes a rotating member 202. The rotating member 202 includes a rotating column 2021 rotatably connected to the inside of the movable sleeve 2012. The rotating column 2021 is rotatably connected to the inside of the movable sleeve 2012 through a bearing. Spiral grooves 2022 are formed in both of the two support rods 2014. Fixed shafts 2023 are fixed at both ends of the rotating column 2021, and the fixed shafts 2023 slide in the spiral grooves 2022.

[0040] When the rotating column 2021 rotates, the fixed shafts 2023 will slide in the spiral grooves 2022. Through their cooperation, the support rods 2014 can be driven to move into the support frame 2013, so that the support rods 2014 can drive the electromagnets 2015 to contact the first ferrule 104 or the second ferrule 105.

[0041] Specifically, the switching component 200 further includes a driving member 203. The driving member 203 includes a movable rod 2031 inserted into the interior of the movable sleeve 2012. A first spring 2032 is fixed to the bottom end of the movable rod 2031. A support plate 2033 is fixed inside the movable sleeve 2012. The bottom end of the first spring 2032 is fixed to the support plate 2033. A cylinder 2034 is provided at the top of the support frame 2011. A connecting plate is fixed to the top of the movable rod 2031. Multiple movable rods 2031 are connected and fixed through the connecting plate. The output end of the cylinder 2034 is fixed to the connecting plate. An installation frame is fixed to the top of the support frame 2011. The cylinder 2034 is fixed inside the installation frame.

[0042] When the cylinder 2034 extends outwards, it will push the movable rod 2031 to move downwards. At this time, the movable rod 2031 will push the first spring 2032, and drive the movable sleeve 2012 to move downwards through the first spring 2032. When the movable sleeve 2012 cannot move downwards, if the movable rod 2031 continues to move downwards, it will compress the first spring 2032. At this time, the movable rod 2031 can still continue to move downwards.

[0043] Specifically, the switching component 200 further includes a transmission member 204. The transmission member 204 includes a winding wheel 2041 fixed to the outside of the rotating column 2021. A pull rope 2042 is wound and fixed around the outside of the winding wheel 2041. The pull rope 2042 passes through the support plate 2033 and is movably connected inside the support plate 2033. A positioning wheel 2043 is fixed to the inner wall of the movable sleeve 2012. One end of the pull rope 2042 bypasses the positioning wheel 2043 and is fixed to the movable rod 2031. An activity groove is provided on one side of the movable rod 2031. The positioning wheel 2043 is used for guiding and positioning the pull rope 2042.

[0044] When the first spring 2032 is not compressed, the movable rod 2031 and the movable sleeve 2012 move synchronously without exerting a pulling force on the pull rope 2042. When the movable sleeve 2012 cannot move and the movable rod 2031 continues to move downwards, at this time, the movable rod 2031 will exert a pulling force on the pull rope 2042. At this time, the pull rope 2042 can drive the winding wheel 2041 to rotate, and thus drive the rotating column 2021 to rotate through the winding wheel 2041.

[0045] Specifically, a second spring 2016 is fixed to one side of the support rod 2014. The other end of the second spring 2016 is fixed to the inner wall of the support frame 2013. When the support rod 2014 moves towards the inside of the support frame 2013, it will squeeze the second spring 2016. When the cylinder 2034 drives the movable rod 2031 to move upwards, since the first spring 2032 is in a compressed state at this time, the movable sleeve 2012 cannot move upwards with the movable rod 2031. Instead, the movable rod 2031 moves upwards alone. At this time, the pull rope 2042 will be in a relaxed state, and the winding wheel 2041 will lose the pulling force for rotation.

[0046] At this time, the second spring 2016 will exert a thrust on the support rod 2014, causing it to move outward from the support frame 2013. When the support rod 2014 moves, it will drive the rotating column 2021 to rotate in the reverse direction through the cooperation of the fixed shaft 2023 and the spiral groove 2022, and drive the winding wheel 2041 through the rotating column 2021 to wind up the relaxed pull rope 2042.

[0047] Specifically, a locking member 106 is provided on the first ferrule 104. The locking member 106 includes a fixed frame 1061 fixed to one side of the first ferrule 104. A slot 105-1 is formed on the second ferrule 105. The fixed frame 1061 is inserted into the slot 105-1. A clamping block 1062 is arranged in the fixed frame 1061. One side of the clamping block 1062 is inclined. A clamping groove 105-2 is formed in the second ferrule 105. The clamping block 1062 is engaged with the clamping groove 105-2.

[0048] When both the first ferrule 104 and the second ferrule 105 are clamped outside the groove 103, the fixed frame 1061 will be inserted into the slot 105-1. At the same time, the clamping block 1062 will be engaged with the clamping groove 105-2. Through the cooperation of the two, the first ferrule 104 and the second ferrule 105 can be connected and locked, so that the two cannot be separated, thereby avoiding the situation that the two will be separated during use.

[0049] Embodiment 3 Refer to Figures 1-10 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0050] Specifically, a positioning plate 1063 is fixed to the top of the clamping block 1062. A third spring 1064 is fixed to the bottom of the positioning plate 1063. The bottom end of the third spring 1064 is fixed to the inner wall of the fixed frame 1061. The third spring 1064 is used to exert a downward pulling force on the positioning plate 1063, and drive the clamping block 1062 to be more firmly engaged with the clamping groove 105-2 through the positioning plate 1063.

[0051] Specifically, a plug rod 1065 is inserted into the second ferrule 105. The bottom end of the plug rod 1065 penetrates into the slot 105-1. An opening groove is formed on one side of the fixed frame 1061. When the fixed frame 1061 enters the inside of the slot 105-1, the plug rod 1065 will enter the fixed frame 1061 from the opening groove and be magnetically fixed to the top of the positioning plate 1063.

[0052] An extrusion rod 1066 is fixed to one side of the support rod 2014. The end of the extrusion rod 1066 is inclined. A stress groove 1065-1 is formed on the plug rod 1065. The bottom end of the plug rod 1065 is connected and fixed to the positioning plate 1063 through a magnet.

[0053] When the support rod 2014 moves towards the second sleeve 105, it will drive the inclined surface at the end of the extrusion rod 1066 to contact the force-receiving groove 1065-1, apply an upward thrust to the force-receiving groove 1065-1, and cause the insertion rod 1065 to move upward. At this time, the insertion rod 1065 will drive the positioning plate 1063 and the clamping block 1062 to move under the suction force of the magnet, and the clamping block 1062 will be separated from the clamping groove 105-2, thereby releasing the fixation of the first sleeve 104 and the second sleeve 105, and then enabling the two to be separated and separated from the groove 103.

[0054] Specifically, a positioning shaft 103-1 is fixed to the inner wall of the groove 103, and positioning holes 100-1 are formed in the inner sides of the first sleeve 104 and the second sleeve 105. The positioning shaft 103-1 is engaged with the positioning holes 100-1, and the two are used in cooperation to limit the first sleeve 104 and the second sleeve 105, so that the two can rotate synchronously with the pressing roller 102.

[0055] During use, when the first sleeve 104 and the second sleeve 105 are clamped outside the groove 103, the surface of the pressing roller 102 will become smooth. In this state, the pressing roller 102 can make the soil surface reach a high level of flatness, providing a good surface environment for crop growth, especially suitable for crops with high requirements for surface flatness.

[0056] If it is necessary to switch the shape of the pressing roller 102 to another state, the air cylinder 2034 is started to push the movable rod 2031 downward. At this time, the movable rod 2031 will push the first spring 2032, and drive the movable sleeve 2012 to move downward through the first spring 2032, so that it drives the support frame 2013 and the support rod 2014 to move downward. When the support rod 2014 moves down to the specified position, the convex block at the bottom of the movable sleeve 2012 will contact the connection part of the first sleeve 104 and the second sleeve 105. At this time, the movable sleeve 2012 cannot continue to move downward, and at the same time, the two electromagnets 2015 will be located on the sides of the first sleeve 104 and the second sleeve 105.

[0057] When the movable sleeve 2012 cannot move and the movable rod 2031 continues to move downward, the movable rod 2031 will apply a pulling force to the pull rope 2042 at this time. At this time, the pull rope 2042 can drive the winding wheel 2041 to rotate, and thus drive the rotating column 2021 to rotate through the winding wheel 2041. When the rotating column 2021 rotates, the fixed shaft 2023 will slide in the spiral groove 2022, and the two can cooperate to drive the support rod 2014 to move into the support frame 2013, so that the support rod 2014 can drive the electromagnet 2015 to contact the first sleeve 104 or the second sleeve 105. At the same time, under the cooperation of the extrusion rod 1066 and the force-receiving groove 1065-1, the clamping block 1062 will be separated from the clamping groove 105-2 At this time, the electromagnet 2015 can be powered on, so that the magnetic force generated by the electromagnet 2015 attracts the first ferrule 104 and the second ferrule 105. Then, the two will drive the first ferrule 104 and the second ferrule 105 to move outwards respectively and separate from the groove 103. After that, the movable sleeve 2012 will drive the support frame 2013 and the support rod 2014 to move upwards, and drive the first ferrule 104 and the second ferrule 105 to move upwards through the support rod 2014, so that they move above the pressing roller 102.

[0058] At this time, the groove 103 on the surface of the pressing roller 102 is exposed, and the state of the pressing roller 102 is switched. When the pressing roller 102 rolls in this state, it can break up the soil clods. For fields with hard soil texture and many soil clods, it can better improve the soil structure, make the seeds fully contact with the fine soil. Furthermore, without disassembling and replacing the pressing roller 102, the pressing roller 102 can be adapted to different working scenarios, thus saving a lot of time and energy and improving the working efficiency.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
