Description

Technical Field

[0001] The utility model relates to the technical field of sowing, in particular to an agricultural automated rapid soil turning and quantitative sowing and covering device. Background Art

[0002] Automation refers to the process by which machinery, equipment, systems or processes achieve the desired goals through automatic operation without or with little direct human involvement. Automation is now widely used in industry, agriculture, military and other fields. The device for rapid soil turning, quantitative seeding and covering in agriculture usually refers to an agricultural seeder.

[0003] Before using, the current seeder needs to be pushed from the farmer's home to the sowing site. During the pushing process, it may walk on the cement floor. In this way, it is necessary to avoid the seeder from contacting the ground and damaging the ground. At the same time, the furrowing depth needs to be adjusted according to the sowing type. The furrowing depth is generally adjusted by adjusting the height of the covering wheel. The height adjustment of the covering wheel requires farmers to squat on the ground and hold the main body of the seeder steady. For this reason, we propose an agricultural automation device for rapid soil turning and quantitative sowing and covering. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1-5 The utility model provides a technical solution: an agricultural automated rapid soil turning and quantitative sowing and covering device, comprising a seeder body 1 and a soil covering wheel 2 and a furrow opener 3 arranged on the seeder body 1, and also comprising: a connecting mechanism 7 arranged between the seeder body 1 and the soil covering wheel 2, through which the height of the soil covering wheel 2 is changed, and an action mechanism 6 arranged on the seeder body 1, and a reverse moving mechanism 4 arranged on the seeder body 1, through which the reverse moving mechanism 4 cooperates with the action mechanism 6 to gradually lower the soil covering wheel 2, and a one-way limiting mechanism 5 arranged between the seeder body 1 and the action mechanism 6, through which the height of the soil covering wheel 2 is limited.

[0027] The reverse movement mechanism 4 includes a pedal 41, which is slidably arranged on the seeder body 1, a spring 42 is arranged between the seeder body 1 and the pedal 41, a rack 411 is arranged on the pedal 41, a gear 43 is rotatably arranged on the seeder body 1, the gear 43 is engaged with the rack 411, a linkage rod 44 is slidably arranged on the seeder body 1, and teeth are arranged on both sides of the linkage rod 44, and one side of the linkage rod 44 is engaged with the gear 43 through the tooth.

[0028] When the pedal 41 is stepped on, the gear 43 rotates through the rack 411, and the position of the linkage rod 44 rises. When the downward pressure on the pedal 41 stops, the pedal 41 is reset under the action of the spring 42. Through the teeth and protrusions arranged on both sides of the linkage rod 44, the gear structure can be connected to both sides of the linkage rod 44 at the same time.

[0029] The action mechanism 6 includes a cross bar 61, which is arranged on the seeder body 1. A ratchet assembly 62 is arranged on the cross bar 61, and a gear 2 621 is arranged on the ratchet assembly 62. The gear 2 621 is rotatably arranged on the cross bar 61. The other side of the linkage rod 44 is engaged with the linkage rod 44 through the tooth protrusion, and a gear 3 63 is arranged on the cross bar 61.

[0030] When the linkage rod 44 is engaged with the gear 2 621 , the gear 2 621 rotates in the opposite direction, and the cross bar 61 rotates through the ratchet assembly 62 , and the gear 3 63 rotates. The ratchet assembly 62 is configured so that the gear 2 621 can only drive the cross bar 61 to rotate in one direction.

[0031] The one-way limiting mechanism 5 includes a limiting rod 51, which is slidably arranged on the seeder body 1, a spring 2 52 is arranged between the limiting rod 51 and the seeder body 1, a handle 53 is arranged at the upper end of the limiting rod 51, and one side of the lower end of the limiting rod 51 is arranged as an inclined surface, and the lower end of the limiting rod 51 is embedded between the gear teeth of the gear 3 63. The limiting rod 51 is lifted by pulling the handle 53, and as the limiting rod 51 rises.

[0032] The connecting mechanism 7 includes a sleeve 71, which is arranged on the seeder body 1. A connecting rod 72 is slidably arranged in the sleeve 71. A rack 2 721 is arranged on the connecting rod 72. The rack 2 721 is engaged with the gear 3 63. An avoidance groove 711 is opened on the sleeve 71. The covering wheel 2 is connected to the sleeve 71 through the connecting rod 72. A spring 3 73 is arranged between the connecting rod 72 and the sleeve 71. The spring 3 73 is embedded in the connecting rod 72.

[0033] When the furrowing depth of the furrow opener 3 needs to be adjusted, the pedal 41 is stepped on to rotate the gear 1 43 through the rack 1 411, and the linkage rod 44 is raised. When the linkage rod 44 is engaged with the gear 2 621, the gear 2 621 is reversely rotated, and the cross bar 61 is rotated through the ratchet assembly 62, and the gear 3 63 is rotated. When the gear 3 63 rotates, since one side of the lower end of the limiting rod 51 is set as an inclined surface, the gear 3 63 can rotate normally, and the rack 2 72 engaged with the gear 3 63 is adjusted. 1, so that the connecting rod 72 descends, and when the downward pressure on the pedal 41 stops, the pedal 41 is reset under the action of the spring 1 42, and the linkage rod 44 descends to make the gear 2 621 rotate forward. Since the ratchet assembly 62 does not drive the gear 3 63 on the cross bar 61 to rotate, and the gear 3 63 cannot rotate autonomously due to the restriction of the restriction rod 51, the repeated downward pressure on the pedal 41 can make the covering wheel 2 on the connecting rod 72 gradually descend, and the trenching depth can be adjusted by adjusting the covering wheel 2;

[0034] When the seeder body 1 has finished its work and needs to leave the work site, the limit rod 51 is raised by pulling the handle 53. As the limit rod 51 rises, the limit rod 51 disengages from the gear three 63, so that the gear three 63 can rotate in both directions, so that the sleeve 71 can be reset under the action of the spring three 73, and the position of the covering wheel 2 rises to the highest position. In this way, when pushing the seeder body 1 away from the work site, there is no need to lift the seeder body 1 as much as possible. It is only necessary to pay attention to the position of the furrow opener 3 to facilitate the pushing of the seeder body 1, or to lower the covering wheel 2 to the lowest position so that the furrow opener 3 does not contact the ground, so as to facilitate the pushing of the seeder body 1 in the idle state. When sowing, the spring three 73 is reset by the limit rod 51, and then the position of the covering wheel 2 is adjusted by stepping on the pedal 41.

[0035] Embodiment 2

[0036] See also Figure 1-6 , the utility model provides a technical solution: an agricultural automated rapid soil turning and quantitative sowing and covering device, embodiment 2 is optimized on the basis of embodiment 1;

[0037] The linkage rod 44 is located at one side of the second gear 621 , and in an initial state, the linkage rod 44 is not engaged with the second gear 621 .

[0038] In the initial state, the linkage rod 44 is not engaged with the gear 2 621 , so when the connecting rod 72 is reset to cause the gear 2 621 to rotate in the opposite direction, it will not affect the linkage rod 44 , thereby preventing the service life of the spring 1 42 from being shortened due to the downward movement of the linkage rod 44 .
