Description

Agricultural spike plow

The present invention relates to an agricultural spike plow that is attached to a tractor (tractor) and used for paddy and field farming, and more specifically, there is no left and right movement of soil during plowing, so that even flat work can be performed during stationary work. Not only is there an agricultural spike plow that makes plowing easier and faster.

Currently, farmers are demanding cultivation technology to reduce rice production cost by entering the era of infinite competition in the international rice market under the WTO and IMF system. Therefore, the farming technique in the future should be able to farm large-scale easily and conveniently. In addition, a cultivation technique that can reduce the labor force, that is, in the case of rice cultivation techniques such as straight or viable hair growth (young mother) is required. 100% of advanced foreign countries have already established direct growing technology. Recently, in order to introduce cultivation technology to reduce rice production cost, Korea is distributing young mother machine rice cultivation technology and direct cultivation technology to farmers. There is a problem that occurs because the mother is not planted. Particularly in direct cultivation, when the seed itself is sown on deep water or on soil surface, germination and germination defects occur due to lack of dissolved oxygen. Seeds that fall on the soil surface on the water are easily dried up or weeds (flowers) are a big problem.

As shown in FIG. 1, one end of the tin 114 is fixed to the frame 112 in the spike plow 110 (angi plow, triple plow, disc plow, etc.) that is being used and spread in existing farms. At the other end of the tin 114, the plow blade 116 is fixed. This conventional spike plow 110 is because the tin 114 is fixed to the frame 112, the plow blade 116 is fixed, so that when the impact on the hard plow blade 116 to accept the shock as it is do.

In general, the spike plow 110 is coupled to the rear body of the tractor 100 to run the balance work while running at 30Km per hour. For example, when a hard work such as a stone hits the plow blade 116 during the balancing operation, the plow plow 110 is lifted by the impact or the plow blade 116 is bent, so it is difficult to evenly balance the ground. In severe cases, the plow blade 116 may be broken, in which case a lot of inconvenience occurs in the work such as stopping the work and replacing the plow blade with a new one.

Therefore, in recent years, attempts are made to precisely balance laser using a laser balancer, but due to the limited use of medium- and small-sized parcels at high prices, it is difficult to use it universally.

Therefore, the purpose of the present invention is to reduce the shock transmitted to the plow blades and tin parts when plowing the ground to prevent the lifting of plows or damage to the plow blades and tin parts and to evenly balance the new types of agricultural spikes. To provide the plow.

According to a feature of the present invention for achieving the above object, an agricultural spike plow is connected to a tractor, the agricultural spike plow used for tilling, comprising: a frame; A coupling support extending from the frame and connected to the tractor; Tins each having a plow blade for plowing at one end thereof; It is installed on the frame at regular intervals, the tin is coupled to each other and includes a cushioning means for mitigating the impact transmitted to the plow blade and the tin part when going to the ground.

Each of the shock absorbing means in the present invention is a fixing plate formed with a through hole and fixed to the frame: a vertical rod is fitted into the through hole so as to be movable up and down in the fixing plate, the lower end of the vertical rod is connected to one end of the tin Wow; A holding plate coupled to an upper end of the vertical rod; A spring fitted to the vertical rod and positioned on the fixed plate to elastically support the pressing plate; And a support mounted to the frame and supporting a predetermined portion of the tin.

In the present invention, the length of the plow blade is about 370mm, the length of the tin is about 1270mm, the spacing between the plow blades is characterized in that about 250mm.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 to 4. In the drawings, the same reference numerals are given to components that perform the same function.

2 and 3 are a side view and a front view showing the agricultural spike plow according to an embodiment of the present invention. 4 is an enlarged view of a portion of FIG. 2.

As shown in FIGS. 2 to 4, the concentrated spike plow 10 is connected to the frame 12, tines 14, plow blades 16, support 40 and cushioning means 20. It's big.

The frame 12 is integrally formed with a coupling support 18 connected to the three-point link of the tractor 50. (See FIG. 6) Tines 14 are installed in the frame 12 at regular intervals. The tines 14 may be divided into horizontal portions and curved portions as shown in FIG. The tins 14 are installed in two rows in the frame 12, in which the tins 14 installed in the front row and the tins 14 installed in the rear row cross each other (see FIG. 3). At the bottom of the plow blades 16 for plowing the ground are installed respectively. For example, the length of the plow blade 16 is about 370mm, the interval between the plow blade 16 and the plow blade 16 is 250mm, the length of the tin is 1270mm, the height of the tin is preferably made of 760mm.

On the other hand, the support 40 is for supporting the frame 12 from the ground so that the frame 12 can stand on the ground when not using the spike plow. One end of the support 40 is fitted into the fitting hole formed in the frame 12 and the other end is placed on the ground. The support 40 can be separated before plowing the ground by connecting the spike plow to the tractor.

The buffer means is configured to mitigate the impact transmitted to the plow blades 16 and the tin 14 when going to the ground. The impact is caused when a plunge or hard hits the plow blade (16) during ground leveling. This cushioning means is installed on the frame 12 in which the tins 14 are located and connected to one end of the tins 14, respectively. Referring to FIG. 4 again, the configuration of the buffer means includes a fixing plate 22, a vertical rod 24, a pressing plate 27, a spring 28, and a support 30. The fixing plate 22 is fixed to the frame 12. The through hole 22a is formed in the horizontal surface of this fixing plate 22. The vertical rod 24 is fitted into the through hole 22a and installed to allow vertical movement. The lower end of the vertical rod 24 is hinged to one end of the tin 14 and the pressing plate 26 is mounted on the upper end. For example, the pressing plate 26 may be integrally formed with the vertical rod 24. The spring 28 is fitted between the vertical rod 24 and is positioned between the fixing plate 22 and the pressing plate to elastically support the pressing plate 26. Preferably, the length of the spring 28 is about 350 mm. The function of this spring will be explained in more detail later. The support portion 30 is mounted to the frame 12 and supports a predetermined portion (the boundary between the horizontal portion and the curved portion) of the tin 14. The support part 30 is the tin 14 so that the lower portion (curvature) of the tin 14 can be rotated up, and the upper portion (horizontal portion) of the tin can be rotated downward when an impact is applied to the plow blade 16. Has a function of supporting a predetermined portion of the. The tin can be rotated around the support part 30, and at this time, the vertical rod 24 is also moved downward to compress the spring 28. (See Fig. 5)

In the present invention, the five non-active spike plow is described as an example, but the size of the frame 12 is proportional to the horsepower Hp according to the difference in the tractor's traction capacity, and the tines 14, the plow blades 16 and the cushioning means The number of mounting can be different. For example, it can manufacture with a concentrated spike plow, such as 9 or 7 loins.

The spike plow 10 of the present invention is connected to each of the tins 14 on which the plow blades 16 are mounted to buffer means. The spike plow having such a configuration is coupled to the rear end of the tractor 50 to run at 30 km / h, evenly. (Refer to FIG. 6). When it hits, a cushioning operation as shown in FIG. 5 is made. First, while the curved portion of the tin 14 is rotated upward with respect to the support 30, the horizontal portion of the tin 14 is rotated downward. The vertical rod 24 coupled to the end of the horizontal portion is moved downward. The pressing plate 26 coupled to the upper end of the vertical rod 24 compresses the spring 28. The shock transmitted to the plow blade 16 and the tin 14 as described above is mitigated by the cushioning operation of the buffer means 20. Therefore, it is possible to prevent the spike plow from lifting or damaging the plow blade 16 or the tin 14. On the other hand, when the impact is relieved, the pressing plate 26 is lifted up by the elastic force of the compressed spring 28, and is operated in reverse. Accordingly, the tin 14 and the plow blade 16 are moved to their original positions (states for the leveling work) and can evenly level the work.

Application of this invention has the following effects.

First, there is almost no movement of soil left and right in paddy field plowing. Second, it is possible to perform precise and even stop work during the balancing work using the rotary work machine. Third, the uniform stopping work can relate water to a certain height in the paddy field, which makes the lodge rate very low when feeding young mosquitoes, and increases the hair growth rate when direct growing. In addition, large paddy fields can save a lot of time and effort. Therefore, the user can reduce the rice production cost and improve the quality, there is an additional advantage that can increase the national competitiveness of our agricultural products.
