Description

Technical Field

[0001] The invention relates to the technical field of sowing, in particular to an anti-clogging corn sowing device. Background Art

[0002] A corn seeder is a planting machine that sows corn seeds, and can also take into account crops such as soybeans. The working principle of a corn seeder is mainly to drive the seed meter and fertilizer meter to work through the rotation of the ground wheel. The seed meter discharges the corn seeds evenly according to the set sowing amount and plant spacing. The seeds fall into the opened sowing furrow through the seed delivery tube. At the same time, the fertilizer meter applies fertilizer near the seeds according to the requirements of the fertilizer application amount. When sowing, a large amount of corn seeds will be placed in the seed storage box, which can avoid frequent seed addition. A large amount of corn seeds will accumulate in the feed tube. Since the surface of the corn seeds will be coated with pesticides, This causes the corn seeds to stick together. If too many corn seeds are piled up in the feed pipe, the mutual squeezing between the seeds will cause the seeds to stick together. When the seeds stick together, the seed meter cannot discharge the seeds evenly according to the set sowing amount and plant spacing during operation, because the stuck seeds may be discharged in clumps instead of single grains or several evenly distributed grains together. This will cause uneven distribution of seeds in the field. If the stuck seed clumps are large, they may get stuck when passing through the narrow part of the feed pipe or the seed discharge port, thereby hindering the normal discharge of subsequent seeds and causing the seeder to be blocked.

DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Example 1 Reference Figure 1-Figure 7 , which is the first embodiment of the present invention, and provides an anti-clogging corn sowing device. The anti-clogging corn sowing device includes a sowing assembly 100, including a frame 101, a seed meter 102 is arranged on the frame 101, a feed pipe 103 is fixed to one side of the seed meter 102, and a seed storage box 104 is fixed to the top of the feed pipe 103.

[0036] The frame 101 is provided with parts such as ground wheels that assist the seeding device 102. The seed storage box 104 is used to store corn seeds in and out. The feed pipe 103 is connected to the seeding device 102 and is used to transport the seeds in the seed storage box 104 to the seeding device 102. In this way, the seeding of corn seeds can be completed through the seeding device 102. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0037] The anti-blocking component 200 is arranged in the feeding tube 103, and includes a feeding part 201. The feeding part 201 includes a rotating cylinder 201a, and the rotating cylinder 201a is rotatably connected to the feeding tube 103 through a rotating shaft. A blocking block 201b is fixed in the feeding tube 103, and one side of the blocking block 201b is in contact with the rotating cylinder 201a and is movably connected to the rotating cylinder 201a. A feeding groove 201a-1 is provided on the rotating cylinder 201a. A motor 201c is fixed on one side of the feeding tube 103, and the output shaft of the motor 201c is fixed to the rotating cylinder 201a.

[0038] There are two blocking blocks 201b, which are respectively located on both sides of the rotating cylinder 201a. The tops of the two blocking blocks 201b are inclined. The two sides of the rotating cylinder 201a are blocked by the two blocking blocks 201b to prevent the seeds inside the seed box 104 from falling down through the two sides.

[0039] The motor 201c is fixed to one side of the feed tube 103 through a bracket, and is used to drive the rotating drum 201a to rotate. When the feed trough 201a-1 of the rotating drum 201a rotates upward, the seeds in the seed box 104 will enter the rotating drum 201a through the feed trough 201a-1. When the feed trough 201a-1 rotates downward, the seeds in the rotating drum 201a will fall downward, thereby transporting the seeds in the seed box 104 to the feed tube 103, and the seeds will be transported in a quantitative manner, thereby avoiding excessive accumulation of seeds in the feed tube 103, which will cause adhesion between seeds, thereby causing blockage in the feed tube 103, and the seed feeding speed of the rotating drum 201a is slightly faster than the sowing speed of the seed meter 102, thereby ensuring that the seeds in the feed tube 103 are always sufficient.

[0040] The anti-blocking component 200 also includes a clearing piece 202, which includes a movable frame 202a. The movable frame 202a is located in the discharge pipe 103. A reciprocating roller 202b is rotatably connected in the discharge pipe 103. A fixed sleeve 202c is fixed on the inner side of the discharge pipe 103. A fixed shaft 202d is fixed in the fixed sleeve 202c. The fixed shaft 202d is meshed with the reciprocating roller 202b.

[0041] The movable frame 202a is rectangular and has four push rods fixed on the inside. When the reciprocating roller 202b rotates, it drives the fixed sleeve 202c and the movable frame 202a to move up and down through the fixed shaft 202d. When the movable frame 202a moves up and down, the inside of the feed pipe 103 can be unblocked and the stuck corn seeds can be broken up, so as to avoid the blockage of the feed pipe 103 and the leakage of seeds caused by the seed metering device 102.

[0042] Example 2 Reference Figure 2-Figure 12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, the anti-blocking component 200 also includes a transmission member 203, which includes a worm wheel 203a, which is fixed to the top of the reciprocating roller 202b, a protective box 203b is provided on the outside of the worm wheel 203a, a worm 203c is rotatably connected inside the protective box 203b, the worm 203c is meshed with the worm wheel 203a, one end of the worm 203c passes through the outside of the discharge pipe 103, and is rotatably connected to the first pulley 203d through a bearing, a second pulley 203e is fixed to the outside of the output shaft of the motor 201c, and the first pulley 203d and the second pulley 203e are connected through a belt drive.

[0044] The protection box 203b is fixed to the inner wall of the feeding tube 103 by means of a mounting column. The top of the protection box 203b is in a pointed cone shape to prevent corn seeds from piling up on the top of the protection box 203b. The protection box 203b is used to protect the meshing portion of the worm 203c and the worm wheel 203a to prevent seeds from getting stuck between the two.

[0045] When the motor 201c rotates, it will drive the second pulley 203e to rotate, and the second pulley 203e will drive the first pulley 203d to rotate through the belt. When the first pulley 203d is connected to the worm 203c, the first pulley 203d will drive the worm 203c to rotate, and the worm 203c will drive the worm wheel 203a to rotate, so that the worm wheel 203a can drive the reciprocating roller 202b to rotate.

[0046] Specifically, the anti-blocking component 200 also includes a connecting member 204, which includes a gear 204a. The gear 204a is located on the outside of the worm 203c. The worm 203c is provided with a slot 203c-1. A block 204b is fixed to the inside of the gear 204a. The block 204b is engaged with the slot 203c-1. A tooth groove 203d-1 is provided on the inside of the first pulley 203d, and the gear 204a cooperates with the tooth groove 203d-1.

[0047] The engagement of the card slot 203c-1 and the card block 204b is used to connect the gear 204a and the worm 203c, so that the gear 204a can move horizontally outside the worm 203c and drive the worm 203c to rotate.

[0048] When the gear 204a moves into the tooth groove 203d-1 and meshes with the tooth groove 203d-1, the first pulley 203d can drive the gear 204a to rotate when it rotates, so that the gear 204a can drive the worm 203c to rotate.

[0049] Specifically, a force block 204c is fixed on one side of the gear 204a, an extrusion rod 204d is provided on one side of the discharge pipe 103, a first spring 204e is fixed on one side of the force block 204c, the other end of the first spring 204e is in contact with the first pulley 203d, and the force block 204c is conical.

[0050] When the extrusion rod 204d rotates, it will approach the force block 204c. When the extrusion rod 204d rotates a certain angle and squeezes the inclined surface of the force block 204c, it can push the force block 204c to move, so that the force block 204c can drive the gear 204a to engage with the tooth groove 203d-1.

[0051] When the extrusion rod 204d is separated from the force-bearing block 204c, the first spring 204e can apply a thrust to the force-bearing block 204c, so that the force-bearing block 204c drives the gear 204a to separate from the tooth groove 203d-1.

[0052] Specifically, the anti-blocking component 200 also includes a trigger member 205, which includes a rotating plate 205a. A support shaft 205b is fixed to one side of the rotating plate 205a. One end of the support shaft 205b passes through the outside of the discharge pipe 103 and is rotatably connected to the inside of the discharge pipe 103. The extrusion rod 204d is fixed to the outside of the support shaft 205b. A rotating frame 205e is sleeved on the outside of the rotating plate 205a. The end of the rotating plate 205a is rotatably connected to a connecting rod 205c through a rotating shaft.

[0053] There are two rotating plates 205a and two rotating frames 205e, which are arranged vertically. The two rotating frames 205e are connected in a V shape. The two rotating frames 205e are connected by a connecting rod 205c so that the two rotating frames 205e can rotate simultaneously.

[0054] If there is no accumulation of seeds inside the feed tube 103, the height of the seeds will not contact the rotating frame 205e, and the rotating frame 205e will remain in the current state.

[0055] When the seeds inside the lower feeding tube 103 are piled up due to adhesion, and seeds continue to fall downward from the top, the seeds inside the lower feeding tube 103 will continue to increase. When its height contacts the rotating frame 205e, it will apply an extrusion force to the rotating frame 205e, and make the rotating frame 205e rotate toward one side of the inner wall of the lower feeding tube 103. When the rotating frame 205e rotates, it will drive the rotating plate 205a and the support shaft 205b to rotate, so that the support shaft 205b can drive the extrusion rod 204d to rotate, and the extrusion rod 204d can squeeze the force block 204c.

[0056] By providing two sets of rotating plates 205a and rotating frames 205e, it can be ensured that the rotating frames 205e and rotating plates 205a can be rotated regardless of whether the inside of the discharge tube 103 is stacked upward from the bottom or stacked downward from the top.

[0057] Specifically, a material guide plate 205d is fixed to one side of the inner wall of the feeding tube 103, and the material guide plate 205d is inclined downward.

[0058] By setting the guide plate 205d, the falling corn seeds can be concentrated on one side of the rotating frame 205e, and when the seeds below rise upward, they will also be concentrated on one side of the rotating frame 205e.

[0059] Example 3 Reference Figure 1-Figure 13 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0060] Specifically, the anti-blocking component 200 also includes an intercepting member 206, which includes a baffle 206a. A slot 201b-1 is provided in the blocking block 201b, and the baffle 206a is inserted into the slot 201b-1. A fixing rod 206b is fixed to the bottom of the baffle 206a. A supporting frame 206c is fixed to the inner wall of the discharge pipe 103. A movable plate 206d is inserted into the supporting frame 206c. A positioning shaft 206e is fixed to the end of the movable plate 206d. A positioning groove 206b-1 is provided on the fixing rod 206b, and the positioning shaft 206e slides in the positioning groove 206b-1.

[0061] The baffle 206a is arc-shaped, and the support frame 206c is used to support the movable plate 206d. When the movable plate 206d moves, it will drive the fixed rod 206b to move through the cooperation of the positioning groove 206b-1 and the positioning shaft 206e, so that the fixed rod 206b can drive the baffle 206a to move toward the bottom of the rotating cylinder 201a, thereby intercepting the seeds falling from the rotating cylinder 201a, thereby avoiding blockage in the discharge pipe 103. When seeds continue to fall from above, the blockage in the discharge pipe 103 will be aggravated.

[0062] Specifically, a connecting column 206f is fixed on one side of the movable plate 206d, a movable groove 103-1 is opened on the discharge pipe 103, the connecting column 206f slides in the movable groove 103-1, a rotating rod 206g is fixed on the outer side of the support shaft 205b, an extrusion groove 206g-1 is opened on the rotating rod 206g, and the support shaft 205b is movably connected with the extrusion groove 206g-1.

[0063] When the upper support shaft 205b rotates, it drives the rotating rod 206g to rotate. The rotating rod 206g drives the connecting column 206f to move through the cooperation of the extrusion groove 206g-1, so that the connecting column 206f drives the moving plate 206d to move.

[0064] Specifically, a positioning column 206h is fixed to one side of the rotating rod 206g, and a positioning block 206i is fixed to one side of the feeding tube 103, and the positioning column 206h is movably connected to the positioning block 206i.

[0065] The positioning column 206h is arc-shaped and coaxial with the rotation angle of the rotating rod 206g. The positioning column 206h cooperates with the positioning block 206i to position the rotating rod 206g. Specifically, a second spring 206j is sleeved on the outer side of the positioning column 206h, and two ends of the second spring 206j are respectively fixed to the positioning block 206i and the rotating rod 206g.

[0066] When the seeds are cleared and the height is lowered, the second spring 206j applies a thrust to the rotating rod 206g to reset the rotating rod 206g and reset the baffle 206a and the rotating plate 205a at the same time.

[0067] When in use, during sowing, the motor 201c is started to drive the rotating drum 201a to rotate, and when the feed trough 201a-1 of the rotating drum 201a rotates upward, the seeds in the seed box 104 will enter the rotating drum 201a through the feed trough 201a-1, and when the feed trough 201a-1 rotates downward, the seeds in the rotating drum 201a will fall downward, thereby the seeds in the seed box 104 can be transported to the feed pipe 103, and the seeds can be transported in a quantitative manner, thereby avoiding excessive accumulation of seeds in the feed pipe 103, which will cause adhesion between seeds, thereby causing blockage in the feed pipe 103, and the seed feeding speed of the rotating drum 201a is slightly faster than the sowing speed of the seed meter 102, thereby ensuring that the seeds in the feed pipe 103 are always sufficient.

[0068] When the seeds inside the lower feeding tube 103 are piled up due to adhesion, and at this time, seeds will continue to fall downward from the top, the seeds inside the lower feeding tube 103 will continue to increase. When its height contacts the rotating frame 205e, it will apply an extruding force to the rotating frame 205e, and cause the rotating frame 205e to rotate toward one side of the inner wall of the lower feeding tube 103. When the rotating frame 205e rotates, it will drive the rotating plate 205a and the support shaft 205b to rotate, so that the support shaft 205b can drive the extrusion rod 204d to rotate. When the extrusion rod 204d rotates, it will approach the force block 204c. When the extrusion rod 204d rotates a certain angle and squeezes the inclined surface of the force block 204c, it can push the force block 204c to move, so that the force block 204c can drive the gear 204a to engage with the tooth groove 203d-1.

[0069] At this time, when the first pulley 203d rotates, it can drive the gear 204a to rotate, so that the gear 204a can drive the worm 203c to rotate, and the worm 203c can drive the worm wheel 203a to rotate, so that the worm wheel 203a can drive the reciprocating roller 202b to rotate. When the reciprocating roller 202b rotates, it will drive the fixed sleeve 202c and the movable frame 202a to move up and down through the fixed shaft 202d. When the movable frame 202a moves up and down, it can dredge the inside of the feeding pipe 103 and break up the stuck corn seeds, so as to avoid the blockage of the feeding pipe 103 and the leakage of the seed metering device 102.

[0070] When the upper support shaft 205b rotates, it will drive the rotating rod 206g to rotate. The rotating rod 206g drives the connecting column 206f to move through the cooperation of the extrusion groove 206g-1, so that the connecting column 206f can drive the movable plate 206d to move. When the movable plate 206d moves, it will drive the fixed rod 206b to move through the cooperation of the positioning groove 206b-1 and the positioning shaft 206e, so that the fixed rod 206b can drive the baffle 206a to move to the bottom of the rotating cylinder 201a, so as to intercept the seeds falling from the rotating cylinder 201a, thereby avoiding blockage inside the discharge pipe 103. When seeds continue to fall from above, the blockage inside the discharge pipe 103 will be aggravated.

[0071] 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.
