Description

Technical Field

[0001] The utility model mainly relates to the field of agricultural machinery, in particular to an automatic furrowing mechanism for pea sowing. Background Art

[0002] The function of the furrowing mechanism is mainly to open a seed furrow when the seeder is working, guide the seeds and fertilizers into the seed furrow, and cover the seeds and fertilizers with wet soil. The front section of the furrowing mechanism is equipped with a plow. According to the angle of the plow entering the soil, it can be divided into an acute-angle furrowing mechanism and an obtuse-angle furrowing mechanism. When sowing peas, an acute-angle furrowing mechanism is generally used due to the sowing requirements of peas.

[0003] The existing furrowing mechanism only has one plow blade, which requires multiple reciprocating movements and cannot simultaneously open multiple furrows, resulting in low working efficiency. In addition, the plow blade arm lacks a limiting structure. When the reducer fails, the plow blade may rotate to the top of the furrowing mechanism, thereby damaging the furrowing mechanism, resulting in low safety. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of the utility model is to provide an automatic furrowing mechanism for pea sowing, in which the main coulter and the auxiliary coulter on the coulter frame work synchronously to open multiple furrows at the same time with high working efficiency, and the rotation range of the coulter arm is limited by the limit frame to prevent the coulter from rotating above the mounting plate to improve safety.

[0007] Furthermore, a synchronization rod is inserted between the two lower connecting frames, and the rotation of any one of the lower connecting frames drives the synchronization rod to rotate, thereby driving the other lower connecting frame to rotate synchronously.

[0008] Furthermore, any one of the plow arms is rotatably connected to an adjacent upper connecting frame, the plow arm is rotatably connected to an adjacent lower connecting frame, the plow arm and its adjacent movable arm rotate synchronously, and the rotation range of the plow arm is limited by the movable arm.

[0015] The plow frame vertically connected to the plow arm drives the boat-shaped shovel main plow and auxiliary plow with an entry angle β of 60 degrees and a front cutting angle γ of 35 degrees to work synchronously. The number of auxiliary plows on the plow frame is adjustable, and multiple flat V-shaped furrows can be opened simultaneously according to the furrowing requirements. The work efficiency is high, and the bottom of the upper connecting frame is tightly pressed against the lower connecting frame to limit the rotation of the lower connecting frame relative to the upper connecting frame, thereby further limiting the rotation range of the plow arm, preventing the plow from rotating above the mounting plate, and improving safety.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, an automatic furrowing mechanism for pea sowing includes a mounting plate 1, a reducer 2 is arranged on the top of the mounting plate 1, the reducer 2 is an aluminum alloy worm gear reducer with a model of LM-NEO-50-60-L-0.18kW, and its rated power is 180W, a limit frame 3 is arranged at the bottom of the mounting plate 1, a coulter arm 4 is arranged on both sides of the limit frame 3, a main coulter 6 is fixed between the two coulter arms 4, a coulter frame 5 is fixed on the top of the main coulter 6, and an auxiliary coulter 7 is detachably arranged on the coulter frame 5 by bolts, and the output end of the reducer 2 is drivingly connected with the coulter arm 4.

[0027] The limiting frame 3 includes an upper connecting frame 31, a lower connecting frame 32 and a movable arm 34. The number of the upper connecting frames 31 is two, and the upper connecting frames 31 are fixed to the bottom of the mounting plate 1. Any one of the upper connecting frames 31 is rotatably connected to a plurality of movable arms 34. The number of the lower connecting frames 32 is also two. The lower connecting frames 32 correspond to the upper connecting frames 31 one by one and are rotatably connected to the other end of the movable arm 34. The movable arm 34 rotates relative to the upper connecting frame 31 under the drive of the lower connecting frame 32. The lower connecting frame 32 reaches its rotation limit after rotating to a position close to the bottom of the upper connecting frame 31. The two lower connecting frames 32 are each provided with four corresponding pin holes. A synchronization rod 33 is inserted between two of the corresponding pin holes of the two lower connecting frames 32. The rotation of any one of the lower connecting frames 32 drives the synchronization rod 33 to rotate, thereby driving the other lower connecting frame 32 to rotate synchronously.

[0028] A rotating shaft is provided between any of the plow arms 4 and an adjacent upper connecting frame 31 for rotational connection, and a rotating shaft is provided between the plow arm 4 and an adjacent lower connecting frame 32 for rotational connection. The plow arm 4 and its adjacent movable arm 34 rotate synchronously.

[0029] The coulter frame 5 penetrates two coulter arms 4, and the coulter frame 5 and the two coulter arms 4 are perpendicular to each other. The auxiliary coulter 7 is located at a position of the coulter frame 5 away from the coulter arms 4. The auxiliary coulter 7 is detachably connected to the coulter frame 5 by bolts, and the number of auxiliary coulters 7 on the coulter frame 5 is adjustable. The main coulter 6 is a boat-shaped shovel coulter. The boat-shaped shovel coulter is an agricultural tool widely used in farmland cultivation. When the boat-shaped shovel coulter works on the land, it will insert the coulter into the soil, and then turn over the soil through the pushing force of the plow body, and the groove marks are flat and stable. The ship side angle α of the main coulter 6 is 130 degrees, the soil entry angle β of the main coulter 6 is 60 degrees, and the front cutting angle γ is 35 degrees. The auxiliary coulter 7 has the same structure as the main coulter 6.

[0030] The implementation principle of Example 1 of the present application is as follows: when a furrowing mechanism is needed, a number of auxiliary plowshares 6 are installed on the plowshare frame 5 according to usage requirements, and then the external motor is started to power the furrowing mechanism, and then the output end of the reducer 2 controls the plowshare arm 4 to rotate according to the rated amplitude, thereby driving the main plowshare 6 and the auxiliary plowshare 7 at the bottom of the plowshare arm 4 to work synchronously, lifting, flipping, pushing or squeezing part of the soil, etc., so that a furrow mark is formed in front of the furrow opener; when the reducer 2 fails, the plowshare arm 4 continues to rotate, the movable arm 34 rotates synchronously with the plowshare arm 4, and the lower connecting frame 32 rotates under the drive of the movable arm 34 to a position close to the bottom of the upper connecting frame 31, at which time the rotation limit is reached, and the rotation range of the plowshare arm 4 is limited.

[0031] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the basic features of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
