Technical Field

[0001] The utility model relates to the technical field of rotary tillers, in particular to a rotary tiller for agricultural use which can apply fertilizer in a quantitative manner. Background Art

[0002] A rotary tiller for agriculture is a kind of agricultural mechanical tool, usually used in conjunction with other agricultural vehicles such as tractors. When the tractor drags the rotary tiller in the field, the blade of the rotary tiller rotates to break the soil, turn the soil and restore the soil structure, so that the soil can retain water well. By matching it with a quantitative feed trough box, fertilizer can be spread in a quantitative manner while rotary tilling the land.

[0003] The Chinese patent document with the search announcement number CN218735872U discloses a rotary tiller for agricultural use capable of quantitative fertilizer application, comprising a steel body, a material cart is installed inside the steel body, wheel legs are arranged at the bottom of the material cart, a track groove is provided on the inner bottom side of the steel body, the bottom of the wheel legs is slidably engaged with the inner part of the track groove, a cross bar is connected to the inner side of the top of the steel body, a middle hole is provided at one end of the cross bar, a water pipe is connected to the inner side of the middle hole, spray pipes are arranged equidistantly on the outer side of the water pipe, a motor is fixedly engaged with the outer side of the cross bar, and one end of the motor is externally connected to the motor. A crawler is installed on the side, and a rotary tillage column is movably installed at one end of the inner side of the crawler. The advantage is that when the motor starts to drive the crawler to rotate, the crawler will also drive the rotary tillage column to rotate, so that the rotary knife will turn over the soil surface, so that the fertilizer in the material vehicle can be quantitatively spread on the land, and water can be sprayed on the top of the fertilizer through the spray pipe when the fertilizer contacts the land, so that the fertilizer can react in advance and improve the reaction efficiency. However, in this solution, the fertilizer cannot be stirred and broken when it is poured into the material vehicle, which is prone to fertilizer accumulation and agglomeration. Utility Model Content

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.

[0024] Specifically, first, the fertilizer is poured from the feed hopper 3 into the temporary storage barrel 2. Next, the motor 4 is started, and the motor 4 drives the rotating shaft 5 to rotate. The rotating shaft 5 is directly connected to the spiral blade 6, so that the spiral blade 6 can preliminarily crush and stir the fertilizer in the temporary storage barrel 2. At the same time, the connecting frame 8 is fixed on the turntable 7, and the turntable 7 is fixed on the rotating shaft 5. In this way, the connecting frame 8 can rotate together with the rotation of the rotating shaft 5. A connecting plate 9 is provided inside the connecting frame 8, and the connecting plate 9 is respectively connected to the stirring blade 10 and the sleeve plate 11. The stirring blade 10 can perform secondary stirring on the fertilizer, so that the fertilizer particles are finer and more uniform. In addition, a first spring 13 is provided inside the sleeve plate 11. During the rotation of the rotating shaft 5, the first spring 13 pushes the scraper 12 to better fit the inner wall of the temporary storage barrel 2, thereby effectively scraping off the residual fertilizer. In this way, the fertilizer is fully stirred and crushed in the temporary storage barrel 2, greatly improving the practicality of the rotary tiller.

[0025] Reference Figure 1 and Figure 3 The material discharge assembly includes a discharge pipe 14, one end of which is fixedly connected to the interior of the temporary storage barrel 2, and the other end of the discharge pipe 14 is fixedly connected to a distribution pipe 15, and the interior of the distribution pipe 15 is fixedly connected to a discharge hopper 16;

[0026] Specifically, the fertilizer inside the temporary storage barrel 2 is discharged through the discharge pipe 14, so that the fertilizer can flow into the distribution pipe 15, and then the distribution pipe 15 distributes the fertilizer to each discharge hopper 16, and then the discharge hopper 16 releases the fertilizer, thereby achieving the effect of discharging the fertilizer out of the temporary storage barrel 2.

[0027] Reference Figure 3-Figure 4The bottom of the outer wall of the material box 1 is fixedly connected to a base 17, the inner part of the base 17 is rotatably connected to a central axis 25, and the outer wall of the central axis 25 is fixedly connected to a rotary cutter 18; the inner part of the material box 1 is fixedly connected to a fixed seat 19, and the inner part of the fixed seat 19 is fixedly connected to a snap ring 20; the outer wall of the snap ring 20 is fixedly connected to a disk 21, and the outer wall of the disk 21 is provided with a second spring 24; both ends of the second spring 24 are fixedly connected to the outer wall of the disk 21; the inner part of the base 17 is rotatably connected to a connecting shaft 22, and the outer wall of the connecting shaft 22 is fixedly connected to a baffle 23, and the outer wall of the baffle 23 is slidably connected to the inner part of the base 17;

[0028] Specifically, the fertilizer is sprayed onto the top of the baffle 23 through the discharge hopper 16. When the weight of the fertilizer exceeds a specific value, the baffle 23 will be pulled by the retaining ring 20 and the disc 21, causing the second spring 24 to begin to extend. In this process, the baffle 23 can rotate around the connecting shaft 22 inside the base 17. When the weight of the fertilizer is lower than a specific value, the second spring 24 will pull the baffle 23 back to its original position by elastic force. In this way, the quantitative release of fertilizer can be achieved, ensuring the fixed distribution of fertilizer. This makes the rotary tiller more accurate in applying fertilizer, helps to improve the yield and quality of crops, while saving fertilizer resources and reducing agricultural production costs.

[0029] Working principle: When the fertilizer needs to be fully stirred and crushed, the fertilizer is poured from the feed hopper 3 into the temporary storage barrel 2, and then the motor 4 is started to drive the rotating shaft 5 to rotate, so that the rotating shaft 5 can directly drive the spiral blade 6 to rotate, and then the fertilizer inside the temporary storage barrel 2 is initially crushed and stirred, and then the connecting frame 8 is fixed on the turntable 7, and the turntable 7 is fixed on the rotating shaft 5, so that the connecting frame 8 can rotate with the rotating shaft 5, and then the connecting plate 9 is fixed inside the connecting frame 8, and the connecting plate 9 is respectively connected to the stirring blade 10 and the sleeve plate 11, so that the stirring blade 10 can stir the fertilizer for the second time, and the first spring 13 inside the sleeve plate 11 can push the scraper 12 to better fit the inner wall of the temporary storage barrel 2 to remove the residual The fertilizer is scraped off, so as to achieve the effect of fully crushing and mixing the fertilizer, thereby improving the practicability of the rotary tiller and facilitating the discharge of the fertilizer. When the fertilizer needs to be quantitatively lowered, the fertilizer is sprayed above the baffle 23 through the discharge hopper 16. When the weight of the fertilizer is higher than a specific value, the baffle 23 will be pulled by the retaining ring 20 and the disc 21 to pull the second spring 24, so that the second spring 24 begins to extend, and then the baffle 23 can rotate around the connecting shaft 22 inside the base 17. When the weight of the fertilizer is lower than a specific value, the second spring 24 will be pulled back and reset by the elastic force of the baffle 23, thereby achieving the effect of quantitatively lowering the fertilizer, improving the accuracy of the rotary tiller and ensuring the fixed distribution of the fertilizer.
