Description

Technical Field

[0001] The invention relates to the technical field of sowing, in particular to an intelligent small-grain precision compound direct seeding machine. Background Art

[0002] The compound seeder is an advanced agricultural machinery and equipment that can complete multiple operations at one time, effectively improving the sowing quality and efficiency of wheat and rapeseed. It can complete multiple operations such as soil crushing, loosening, leveling, pre-sowing suppression, uniform strip sowing, and post-sowing suppression at one time, reducing the number of repeated entries of the machine and reducing soil compaction. The compound seeder can sow wheat and rapeseed separately, and when replacing the seeds to be sown, the remaining seeds in the silo and the seed tube need to be completely emptied, and new seeds are added after emptying. This results in a lot of time required for seed replacement, which in turn causes the seeder to be unable to operate normally for a long time, reducing the sowing area per unit time and affecting the overall operation efficiency. In large-scale planting, this may cause the sowing operation to not be completed in time, missing the best sowing season, and having an adverse effect on the growth and yield of crops.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1 Reference Figure 1-Figure 7, which is the first embodiment of the present invention, and provides an intelligent small-grain precision compound direct seeding machine. The intelligent small-grain precision compound direct seeding machine includes a sowing component 100, including a frame 101, an external material bin 102 is arranged on the top of the frame 101, and an internal material bin 103 is fixed on the inner side of the external material bin 102. Two different seeds can be stored respectively through the internal material bin 103 and the external material bin 102.

[0032] A seeding mechanism 104 is provided on one side of the outer silo 102, and a seed placing tube 105 is provided below the seeding mechanism 104. There are multiple seeding mechanisms 104 and seed placing tubes 105, which are evenly distributed in a straight line on one side of the outer silo 102. The seeding mechanism 104 is used to discharge seeds outward into the seed placing tube 105, so as to complete the sowing of seeds. The working principle of the seeding mechanism 104 is the existing technology, and this scheme will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0033] A rotary tillage mechanism is provided below the frame 101, so the sowing assembly 100 of the present invention integrates the processes of tilling the land, pressing, sowing and the like, has good adaptability to sandy soil and clay soil, and can achieve high-standard and high-efficiency precision sowing.

[0034] Doppler radar speed measurement and intelligent control technology are used to accurately control the sowing amount. The bow-shaped integrated maintenance-free seed tray integrates the seedbed trenching, sowing and seed compacting processes to ensure accurate sowing amount and consistent sowing depth. The working principle of this part is existing technology, and technical personnel in this field can set it as needed, which will not be elaborated here.

[0035] The auxiliary component 200 is arranged in the outer silo 102, and includes a discharge pipe 201 fixed to one side of the inner silo 103. The discharge pipe 201 is inclined. The number of the discharge pipes 201 corresponds to the seeding mechanism 104, and the two ends are respectively connected to the seeding mechanism 104 and the inner silo 103, so that the seeds inside the inner silo 103 can enter the seeding mechanism 104.

[0036] The discharge pipe 201 is provided with a discharge chute, which allows the seeds inside the external silo 102 to enter the seeding mechanism 104. A fixing plate is fixed between two adjacent discharge pipes 201, and the seeds inside the external silo 102 can be accumulated on the top of the discharge pipe 201 through the fixing plate.

[0037] A first baffle 202 and a second baffle 203 are disposed in the discharge pipe 201 , and the number of the first baffle 202 and the second baffle 203 corresponds to that of the discharge pipe 201 .

[0038] When it is necessary to sow the seeds inside the outer silo 102, the second baffle 203 is rotated to a vertical state, and the seeds inside the inner silo 103 are intercepted, so that the seeds cannot enter the seeding mechanism 104, and then the first baffle 202 is rotated downward to a vertical state. At this time, the seeds inside the outer silo 102 can enter the seeding mechanism 104 through the feed chute, so that the seeds inside the outer silo 102 can be sown.

[0039] When the seeds to be sown need to be replaced, the first baffle 202 is rotated upward to block the feed trough. After the seeds remaining in the seeding mechanism 104 and the seeding tube 105 are discharged, the second baffle 203 is rotated downward to release the interception of the seeds in the inner silo 103 and allow them to enter the seeding mechanism 104, so that the seeds inside the inner silo 103 can be sown.

[0040] A diverter pipe 204 is provided on one side of the lower seeding pipe 105. The number of the diverter pipes 204 corresponds to the lower seeding pipe 105. One end of the diverter pipe 204 is connected to the lower seeding pipe 105, and the other end extends to the inside of the outer silo 102 and the inner silo 103, and penetrates to the outside of the outer silo 102.

[0041] A first filter screen 205 and a second filter screen 206 are provided in the diverter pipe 204. The diverter pipe 204 is provided with feed holes at the positions of the outer silo 102 and the inner silo 103. The first filter screen 205 is rotatably connected to the diverter pipe 204 through a rotating shaft, and is located in the feed hole corresponding to the outer silo 102 and blocks the feed hole. The second filter screen 206 is vertically fixed on one side of the feed hole corresponding to the inner silo 103. The first filter screen 205 and the second filter screen 206 can intercept seeds.

[0042] When it is necessary to recover the seeds remaining in the seed discharge mechanism 104 and the seed tube 105 to the outer silo 102, the first filter screen 205 is rotated upward to intercept the seeds in the diversion tube 204. When suction is generated inside the diversion tube 204, the seeds falling from the seed tube 105 can be sucked into the diversion tube 204 and intercepted when contacting the first filter screen 205. At this time, the seeds will accumulate above the discharge hole. As the number of seeds increases, the air suction device is intermittently opened and closed, so that the seeds can fall into the outer silo 102 through the discharge hole, thereby completing the recovery of the seeds without discharging the seeds underground or using an additional collection device.

[0043] When it is necessary to recover the seeds remaining inside the seed discharge mechanism 104 and the seed discharge tube 105 to the inner silo 103, the first filter screen 205 is rotated downward to block the discharge hole so that the seeds will not enter the outer silo 102 through the discharge hole. When suction is generated inside the diversion pipe 204, the seeds can be driven to move to one side of the second filter screen 206 and accumulate on one side of the second filter screen 206. At this time, the air suction device is intermittently opened and closed to allow the seeds to fall into the inner silo 103 through the discharge hole, thereby completing the recovery of the seeds. The second filter screen 206 can prevent the seeds from entering the air suction device.

[0044] A first rotating column 202-1 is fixed in the first baffle 202, and a second rotating column 203-1 is fixed in the second baffle 203. The first rotating column 202-1 and the second rotating column 203-1 respectively connect multiple first baffles 202 and second baffles 203 so that they can rotate synchronously when rotating. One end of the first rotating column 202-1 and the first rotating column 202-1 both penetrate to the outside of the outer silo 102.

[0045] The external material bin 102 is provided with a locking member 300, including a mounting block 301 fixed to one side of the external material bin 102, a limiting column 302 is inserted on the mounting block 301, a connecting block 303 is fixed to the top of the limiting column 302, a tension spring 304 is fixed to the bottom of the connecting block 303, the bottom end of the tension spring 304 is fixed to the mounting block 301, and a limiting hole 305 is provided on the first rotating column 202-1. When the limiting column 302 is engaged with the limiting hole 305, the first rotating column 202-1 can be locked by the cooperation of the two to prevent it from rotating at will.

[0046] There are two groups of locking members 300, and the other group corresponds to the second rotating column 203-1 and is also used to lock it. There are two limiting holes 305, which can lock the first rotating column 202-1 or the second rotating column 203-1 at different angles.

[0047] Example 2 Reference Figure 7-Figure 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0048] Specifically, the auxiliary component 200 also includes a blocking piece 208, the number of which corresponds to the feed hole, and the blocking piece 208 includes a support sleeve 208a fixed to the bottom of the diverter pipe 204, the support sleeve 208a coincides with the feed hole, a support ring 208b is fixed inside the support sleeve 208a, and a receiving plate 208c is provided at the bottom of the support ring 208b, and the receiving plate 208c is blocked by the support ring 208b. When suction is generated inside the diverter pipe 204, the receiving plate 208c will not rotate upward, and can block the support sleeve 208a and the feed hole, so as to avoid the suction generated by the diverter pipe 204 from acting on the feed hole, causing the suction inside the diverter pipe 204 to be dispersed, thereby failing to suck the seeds inside the seed tube 105 upward.

[0049] A positioning shaft 208d is fixed on one side of the receiving plate 208c, and the positioning shaft 208d is used to support and position the receiving plate 208c. When the seeds fall downward to the top of the receiving plate 208c, the receiving plate 208c can be opened downward so that the seeds can fall downward. A first torsion spring 208e is fixed on the outside of the positioning shaft 208d, and the other end of the first torsion spring 208e is fixed to the support sleeve 208a. The first torsion spring 208e is used to close the opened receiving plate 208c upward.

[0050] Specifically, the auxiliary component 200 also includes a rotating member 209, which includes a turntable 209a rotatably connected to one side of the discharge pipe 201, a rotating rod 209b is fixed on the rotating shaft in the first filter screen 205, and the rotating rod 209b can drive the first filter screen 205 to rotate. A connecting rod 209c is rotatably connected to one side of the turntable 209a through the rotating shaft, and the other end of the connecting rod 209c is rotatably connected to the rotating rod 209b. The connecting rod 209c is used to connect the turntable 209a with the rotating rod 209b.

[0051] When the rotating disk 209a rotates, the connecting rod 209c can drive the rotating rod 209b to move upward or downward, so that the rotating rod 209b can drive the first filter screen 205 to rotate upward or downward.

[0052] Specifically, a movable groove 209a-1 is opened on the turntable 209a, a first force-bearing rod 209d is arranged in the movable groove 209a-1, a first extrusion rod 209e is fixed to the outside of the first rotating column 202-1, a second force-bearing rod 209f is fixed to one side of the turntable 209a, and a second extrusion rod 209g is fixed to the outside of the second rotating column 203-1.

[0053] When the first rotating column 202-1 drives the first baffle plate 202 to rotate upward, it will also drive the first extrusion rod 209e to rotate downward, and push the first force-bearing rod 209d to rotate downward through the first extrusion rod 209e. At this time, the first force-bearing rod 209d will contact the inside of the movable groove 209a-1, and drive the turntable 209a to rotate, so that the turntable 209a can drive the rotating rod 209b to rotate through the connecting rod 209c, so that the first filter screen 205 can rotate upward and intercept the seeds. Therefore, when the first baffle plate 202 blocks the feed chute, the first filter screen 205 can be rotated upward at the same time to intercept the seeds.

[0054] When the first rotating column 202-1 drives the first baffle 202 to rotate 90 degrees, the first squeezing rod 209e will be separated from the first force rod 209d due to length limitation. Therefore, when the rotating disk 209a rotates in the opposite direction, the first force rod 209d will not contact the first squeezing rod 209e and will not be hindered.

[0055] At the same time, the turntable 209a will drive the second force-bearing rod 209f to contact the second squeezing rod 209g. When the seeds inside the lower seed tube 105 are emptied and the seeds in the inner silo 103 need to be moved outward, the second rotating column 203-1 is rotated to drive the second baffle 203 to rotate downward. At this time, the second squeezing rod 209g will be driven to squeeze the second force-bearing rod 209f, thereby driving the turntable 209a to rotate in the opposite direction, and driving the rotating rod 209b to rotate downward through the connecting rod 209c, so that the first filter screen 205 can be rotated downward to a horizontal state.

[0056] In this state, the seeds inside the diverter tube 204 can be prevented from entering the outer silo 102. When recovering the seeds, it is only necessary to rotate the second baffle 203 upward to intercept the seeds inside the inner silo 103. The seeds inside the diverter tube 204 will directly enter the inner silo 103 under the action of suction.

[0057] When it is necessary to sow seeds inside the external silo 102 again, it is only necessary to rotate the first baffle 202 downward to separate it from the feed chute. At this time, the first squeezing rod 209e will rotate in the direction of the first force-bearing rod 209d and squeeze the first force-bearing rod 209d. At this time, the first force-bearing rod 209d will rotate in the movable groove 209a-1. When the first squeezing rod 209e is reset, it will be separated from the first force-bearing rod 209d. At this time, the first force-bearing rod 209d will return to its original position. When the first squeezing rod 209e is rotated downward again, it can push the first force-bearing rod 209d to rotate downward again, and the above operation is repeated.

[0058] Specifically, an extension rod 209g-1 is inserted into the second extrusion rod 209g, and the extension rod 209g-1 is movably connected to the second extrusion rod 209g for extending the length of the second extrusion rod 209g so that it can push the second extrusion rod 209g to move a sufficient angle.

[0059] A spring 209g-2 is fixed to one side of the extension rod 209g-1, and the other end of the spring 209g-2 is fixed to the inner wall of the second extrusion rod 209g. The spring 209g-2 applies a thrust to the extension rod 209g-1, so that it can move outward.

[0060] Specifically, a guide plate 204-1 is provided at the end of the diverter pipe 204, and a rotating shaft 204-2 is fixed inside the guide plate 204-1. The rotating shaft 204-2 is tightly connected to the diverter pipe 204 to prevent the guide plate 204-1 from rotating at will. Multiple guide plates 204-1 are connected and fixed by a rotating shaft 204-2.

[0061] When it is necessary to recover the seeds in the lower seed tube 105, the guide plate 204-1 is rotated toward the lower seed tube 105 to intercept the seeds falling from the lower seed tube 105, so that the diverter tube 204 can suck away the seeds when generating suction, thus preventing the seeds from falling to the ground.

[0062] A first stopper 204 - 3 is fixed to the inner wall of the shunt pipe 204 . When the guide plate 204 - 1 is in a vertical state, it will be released from the first stopper 204 - 3 and blocked by the first stopper 204 - 3 to prevent it from rotating into the shunt pipe 204 .

[0063] A second stopper 204-4 is fixed inside the lower seed tube 105. When the guide plate 204-1 rotates toward the lower seed tube 105, the guide plate 204-1 can be supported by the second stopper 204-4 to prevent the guide plate 204-1 from opening downward due to the pressure of the seeds.

[0064] Example 3 Reference Figure 1-Figure 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0065] Specifically, a fixed shaft 209d-1 is fixed inside the first force-bearing rod 209d, and the end of the fixed shaft 209d-1 passes through the outside of the turntable 209a. The fixed shaft 209d-1 is used to support and position the first force-bearing rod 209d, and is movably connected with the turntable 209a. A second torsion spring 209d-2 is fixed to the outside of the fixed shaft 209d-1, and the other end of the second torsion spring 209d-2 is fixed to the turntable 209a. The second torsion spring 209d-2 is used to reset the first force-bearing rod 209d after rotation.

[0066] Specifically, a baffle 205-1 is fixed on the inner top wall of the diversion pipe 204 and above the first filter screen 205. When the first filter screen 205 rotates upward, it will contact the baffle 205-1 and support the first filter screen 205 to prevent the first filter screen 205 from being pushed and rotated by the thrust of the seeds.

[0067] Specifically, the first filter screen 205 is rotatably connected to the diverter pipe 204 via a rotating shaft, and the second filter screen 206 is vertically fixed to the inner wall of the diverter pipe 204 .

[0068] Specifically, a connecting pipe 210 is fixed at the end of the diversion pipe 204, and the connecting pipe 210 connects multiple diversion pipes 204. An air suction pump 211 is fixed on one side of the external silo 102. The air suction pump 211 generates suction inside the connecting pipe 210, so that suction can be generated inside the diversion pipe 204. The air suction pump 211 is connected to the connecting pipe 210.

[0069] During use, when it is necessary to sow the seeds inside the outer silo 102, the second baffle 203 is rotated to a vertical state, and it is used to intercept the seeds inside the inner silo 103, so that the seeds cannot enter the seeding mechanism 104, and then the first baffle 202 is rotated downward to a vertical state. At this time, the seeds inside the outer silo 102 can enter the seeding mechanism 104 through the feed chute, so that the seeds inside the outer silo 102 can be sown.

[0070] When it is necessary to replace the sown seeds, the first baffle 202 is rotated upward to block the feed chute. When the first rotating column 202-1 drives the first baffle 202 to rotate upward, it will also drive the first extrusion rod 209e to rotate downward, and push the first force-bearing rod 209d to rotate downward through the first extrusion rod 209e. At this time, the first force-bearing rod 209d will contact the inside of the movable groove 209a-1 and drive the turntable 209a to rotate, so that the turntable 209a can drive the rotating rod 209b to rotate through the connecting rod 209c, so that the first filter screen 205 can be rotated upward to intercept the seeds. Therefore, after the first baffle 202 blocks the feed chute, the first filter screen 205 can be rotated upward at the same time to intercept the seeds.

[0071] At this time, the guide plate 204-1 is rotated toward the lower seed tube 105 to intercept the seeds falling from the lower seed tube 105, and then the air suction pump 211 is started to generate suction inside the diversion tube 204, so that the seeds falling from the lower seed tube 105 can be sucked into the diversion tube 204 and intercepted when contacting the first filter screen 205. At this time, the seeds will accumulate above the feed hole, and as the number of seeds increases, the air suction pump 211 is intermittently opened and closed, so that the seeds can fall into the outer silo 102 through the feed hole, thereby completing the recovery of the seeds without discharging the seeds underground or using an additional collection device.

[0072] At this time, the second baffle 203 is rotated downward to release the interception of the seeds in the inner silo 103 and allow them to enter the seeding mechanism 104, so that the seeds inside the inner silo 103 can be sown, thereby avoiding the need to empty the seeds inside the silo when changing the seeds to be sown, thereby saving time for changing seeds and improving sowing efficiency.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
