Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, and relates to an agricultural machine, in particular to an integrated device for agricultural sowing. Background Art

[0002] No-till seeding technology is a new type of agricultural production method. Compared with the traditional tillage mode, it omits the plowing operation, which not only saves a large amount of time and labor, but also helps to improve the seeding efficiency. In addition, no-till seeding can effectively store water and conserve soil moisture, enhance soil fertility, improve the lodging resistance of crops, and the wheat straw returning to the field also increases the soil organic matter content, improves soil fertility, and improves the soil structure, thus realizing the sustainable development of agriculture.

[0003] A no-till seeder is an agricultural machine that emerged to adapt to the rise of no-till seeding technology. The Chinese Patent Publication No. CN215301468U discloses a utility model patent with the name of a small test seeding and pressing integrated machine. It is towed forward in the field by an external force. The ditching mechanism digs ditches, the pressing rollers of the pressing mechanism roll and press on the ground, and the seeding mechanism is driven to rotate by a transmission mechanism for seeding. The following technical problems will occur in the specific seeding application of the small test seeding and pressing integrated machine disclosed in the above patent.

[0004] 1) In paragraph

[0028] of the specification, the ditching mechanism includes a ditching plow frame arranged at the front part of the frame, and a ditching plow is fixedly connected to the lower end of the ditching plow frame. It can be seen from the upper text of the specification and by reading the specification drawings that the ditching mechanism is connected to the frame by a hard structure. During the seeding process, when any ditching mechanism on the seeding and pressing integrated machine often encounters stones and hard objects, the collision between the ditching mechanism and the stones and hard objects will cause the forward-moving seeding and pressing integrated machine to tilt or vibrate, and in severe cases, it will also cause the bending deformation of the ditching mechanism.

[0005] 2) As described in paragraph

[0030] of the specification, the pressing mechanism includes pressing roller bearing seats arranged on the lower sides of both ends of the frame. A pressing roller shaft is installed on the pressing roller bearing seats, and a pressing roller is arranged on the pressing roller shaft. It can be seen from the upper text of the specification and by reading the specification drawings that the pressing rollers of the pressing mechanism are arranged in an integrated single-roller setting where several ditching mechanisms share one pressing roller. When the surface of the cultivated land is uneven or the heights of the ridges of the field ridges are different, the integrated single-roller pressing mechanism can only press the highest points of the surface of the cultivated land and the ridges of the field ridges. The soil on the crop seeds in the relatively lower field ridges will not be compacted, which will affect the germination rate of the crop seeds and cause a reduction in the yield of the cultivated land.

A screw connecting shaft Ⅰ az and a screw connecting shaft Ⅱ ay penetrate through the tail clamping plates 1g. The two tail clamping plates 1g are symmetrically connected left and right by two connecting screws af. The connecting sleeve Ⅰ 1c and the connecting sleeve Ⅱ 1z are arranged through the plate surfaces of the two tail clamping plates 1g.

[0048] Specifically Figure 5 Figure 6 As shown, the groove blade assembly 14 of the ditching, sowing, and pressing integrated device of the agricultural seeder of the present utility model includes a connecting knife shaft 1h, a knife connecting plate 1i, a clamping knife plate 1j, a groove knife 1k, a connecting hanging shaft 1L, and a shock-absorbing part 1m. The knife connecting plate 1i is connected to the tail clamping plate 1g of the tail clamp assembly 13 through the connecting knife shaft 1h. The groove knife 1k is arranged at the lower end of the knife connecting plate 1i through the clamping knife plate 1j. The connecting hanging shaft 1L is arranged at the upper end of the knife connecting plate 1i. The ditching and sowing device 1 is rotationally connected to the connecting sleeve Ⅱ 1z of the tail clamping plate 1g of the tail clamp assembly 13 through the connecting knife shaft 1h, and rotates and adjusts its angle relative to the tail clamp assembly 13 with the connecting knife shaft 1h as the center point.

[0049] More specifically Figure 5 Figure 6 As shown, the clamping knife plate 1j is composed of left and right symmetrically arranged clamping plates 1j1 and clamping bolts 1j2. The lower end of the clamping plate 1j1 is connected to the groove knife 1k through the clamping bolt 1j2, and the upper end of the clamping plate 1j1 is connected to the knife connecting plate 1i through the clamping bolt 1j2.

[0050] More specifically Figure 5 Figure 6As shown, the shock absorber 1m includes a spring fixing plate 1m1, a compression spring 1m2, and a top shaft bolt 1m3. The spring fixing plate 1m1 is connected to the tail clamping plate 1g of the ditching and seeding device 1, and the compression spring 1m2 is sleeved on the top shaft bolt 1m3.

The front connection shaft 1e1 is fork-hung on the outer sides of the two long side plates 1b2, and the upper connecting rod 1f is inserted into the middle gap between the two long side plates 1b2. The shaft connection part 1d2 of the lower suspension part 1d, the upper connecting rod 1f, and the front connection shaft 1e1 of the middle spring part 1e are rotatably connected with the long side plate 1b2 among the four.

[0056] As Figure 2 Figure 3 As shown, the bomb suspension assembly 12 and the tail clip assembly 13 are connected at three points. Specifically, the rotation connection shaft ac of the rear connection shaft 1e2 of the lower suspension part 1d of the bomb suspension assembly 12 is sleeved in the connection sleeve I 1c of the tail clip assembly 13. The convex hole platform ae of the rear connection shaft 1e2 of the spring part 1e of the bomb suspension assembly 12 is sleeved on the screw connection shaft II ay of the tail clip assembly 13.

The shaft connection part 1d2 of the lower suspension part 1d, the upper connecting rod 1f, and the rear connection shaft 1e2 of the middle spring part 1e are rotatably connected with the tail clip plate 1g among the four.

[0057] As Figure 4 Figure 5 Figure 6 As shown, the light body pressing device 2 and the tail clip assembly 13 are fixedly connected. Specifically, the hanging connection plate 22 of the light body pressing device 2 is inserted into the middle gap between the two tail clip plates 1g and is fixedly connected through the screw connection shaft I az and the screw connection shaft II ay penetratingly arranged on the tail clip plates 1g.

[0058] The integrated ditching, sowing, and pressing device of the agricultural seeder of the present utility model works under the traction of the seeder. Referring to Figure 1 Figure 2 As shown, the ditch blade assembly 14 of the ditching and sowing device 1 drives the seed spreading assembly 15 to insert into the cultivated land soil layer. The ditching and sowing device 1 moves forward under the traction of the seeder. The ditch blade assembly 14 cuts out ridge grooves in the cultivated land soil layer, and the seed spreading assembly 15 located at the rear end of the ditch blade assembly 15 drops crop seeds into the ridge grooves. During the process of the ditch blade assembly 14 and the seed spreading assembly 15 moving forward to open grooves and sow seeds, the soil on both sides of the ridge grooves gathers towards the middle, and the pressing wheel 23 of the light body pressing device 2 rolling forward compacts the soil on the ridge grooves.

[0059] Reference Figure 2 Figure 3 As shown, in the integrated ditching, sowing and pressing device of the agricultural seeder of the present utility model, the elastic hanging component 12 is rotatably connected to the connecting and fixing component 11 and the tail clamping component 13 at multiple points. When the pressing wheel 23 of the light pressing device 2 encounters uneven cultivated land ridge grooves during the forward rolling process, the elastic hanging component 12 which is spaced from the light pressing device 2 generates up and down elastic forces under the action of its elastic member 1e. Furthermore, the pressing wheel 23 of the light pressing device 2 can roll along with the uneven cultivated land ridge grooves.
