Description

Technical Field

[0001] The utility model relates to the technical field of agricultural implements, in particular to a tilling plowshare for agricultural machinery. Background Art

[0002] A plow is a soil tillage machine whose main function is to turn over the soil and also has the functions of loosening and breaking the soil. The plowshare is the most important component of the plow, which determines the depth and effect of loosening the soil. With the continuous development of agricultural automation, the plowshare is usually installed on a tilling machine for use.

[0003] When the plowshare is plowing the land, the plowshare is rigidly connected to the agricultural machinery frame through a joint. Since the agricultural machinery itself vibrates greatly during operation, the connection will become loose after a certain period of use, which can easily cause related parts to fail and affect the normal use of the agricultural machinery. In addition, current plowshares for plowing land are generally stamped from a whole piece of steel plate. Later, during the process of turning the soil in the field, the long-term friction between the metal and the ground will cause metal wear, which will result in the need to replace the entire plowshare, making the replacement cost too high. Although there is a device for replacing the plow tip of the plowshare, which is generally fixed by bolts, when using the device to install the plow tip, the threaded holes at the connection must always be kept corresponding to each other, which is more troublesome to operate.

[0030] A plow is a farming machine whose main function is to turn over the soil. It has the functions of loosening and crushing the soil, and the plowshare is the most important part of the plow. It determines the depth and effect of loosening the soil. The current plowshare is basically similar to the shovel head in appearance. In the plowshare used for plowing, the plowshare is firmly connected to the frame of the agricultural machinery through a connecting rod. Due to the large vibration of agricultural machinery, when working, after a period of use, the connecting rod part will become loose, which is easy to cause failure of related parts and affect the normal use of agricultural machinery. In addition, the plowshare currently used for plowing is generally a whole piece of stamped steel plate. In the process of turning over the soil in the field in the later stage, the long-term friction between the metal and the ground will cause metal wear. In the process of turning over the soil in the field, the long-term friction between the metal and the ground will cause metal wear, which will lead to the need to completely replace the plowshare, making the replacement cost very high, so it needs to be improved.

[0031] Based on this, the inconvenience of replacing the plowshare in the related art and the technical problem of loosening of the plowshare connection part due to vibration can be improved, and the embodiment of the present application provides the following solution.

[0032] The present application embodiment provides a tillage plowshare for agricultural machinery, comprising:

[0033] The plowshare body 10 , a plurality of limiting components 20 and a fixing component 30 , wherein the plowshare body 10 includes a plowshare body 11 and a plurality of plowshare tips 12 , wherein the plowshare tips 12 are mounted on the plowshare body 11 through the limiting components 20 and fixed through the fixing component 30 .

[0034] The limiting assembly 20 includes a connecting block 21, a shock-absorbing pad 22, a pin 23, a baffle 24 and a spring 25. The connecting block 21 is arranged at the tail of the plowshare tip 12. The plowshare body 11 is provided with a groove 111 to install the connecting block 21. The shock-absorbing pad 22 is arranged on the inner wall of the groove 111. The baffle 24 and the spring 25 are installed in the plowshare body 11 by providing a cavity 112. The pin 23 is slidably installed on the side walls of the groove 111. Slots 211 are provided on both sides of the connecting block 21. The baffle 24 is arranged on the pin 23. One end of the spring 25 abuts against the inner wall of the cavity 112, and the other end abuts against the baffle 24. The pin 23 is clamped into the slot 211 through the baffle 24 and the spring 25.

[0035] The plowshare body 11 is provided with a first threaded hole 113 , and the connecting block 21 is provided with a second threaded hole 212 .

[0036] As can be seen from the above, the agricultural machinery plowshare provided by the embodiment of the present application is a kind of plowshare for agricultural machinery. When the plowshare is worn out after long-term use and needs to be replaced, the fixing assembly 30 is taken out, and the pins 23 on both sides of the connecting block 21 are moved to move the pins 23 in the direction away from the connecting block 21 until the pins 23 are disengaged from the slots 211. The user can then easily take out the plowshare tip 12 from the groove 111; take out a new plowshare tip 12, move the pins 23 to disengage the pins 23 from the grooves 111, and the springs 25 are compressed. The connecting block 21 is placed in the grooves 111, and the pins 23 are released. Under the action of their own elastic force, the springs 25 move the baffle 24 and the pins 23 to move towards the connecting block 21. The pin 23 moves to the slot 211 to form a limit, and the preliminary limit installation is completed. The first threaded hole 113 on the plowshare body 11 corresponds to the second threaded hole 212 on the connecting block 21, and then fixed by the fixing assembly 30; therefore, the setting of the connecting block 21, the shock absorbing pad 22, the pin 23, the baffle 24 and the spring 25 is convenient for the staff to perform preliminary installation and limit on the plowshare tip 12 in advance, so that the first threaded hole 113 and the second threaded hole 212 remain in a corresponding state, which is convenient for the fixing assembly 30 to fix it, and further convenient for the staff to replace the plowshare, and the shock absorbing pad 22 plays a role in absorbing the vibration potential energy of the plowshare body 11.

[0037] Optionally, in some embodiments, please read Figure 1 to Figure 2 The fixing assembly 30 includes a bolt 31 and a nut 32. The screw portion of the bolt 31 passes through the first threaded hole 113 and the second threaded hole 212 and is rotatably connected to the nut 32. Silicone pads 33 are provided at the first threaded holes 113 on both sides of the plowshare body 11.

[0038] With such arrangement, after the plowshare tip 12 is preliminarily installed using the limiting assembly 20, when it is necessary to fix the plowshare tip 12, the screw portion of the bolt 31 is aligned with the first threaded hole 113, and passes through the first threaded hole 113 and the second threaded hole 212, and is rotatably connected to the nut 32 on one side of the plowshare body 11, and the head of the bolt 31 and the nut 32 are both against the silicone pad 33; therefore, the arrangement of the bolt 31 and the nut 32 enables the plowshare tip 12 to be better fixedly installed on the plowshare body 11, which is convenient for plowing; the arrangement of the silicone pad 33 is used to protect the side walls of the first threaded holes 113 on both sides of the plowshare body 11, and to make the bolt 31 and the nut 32 form a seal with the plowshare body 11, which is used to reduce the degree of corrosion caused by moisture in the soil to the nut 32 and the connection between the bolt 31 and the plowshare body 11 when the plowshare is plowing.

[0039] Optionally, in some embodiments, see Figure 3 The connecting block 21 is provided with first guide surfaces 213 on both sides of one end away from the plow tip 12 , and the pin shaft 23 is provided with a second guide surface 231 on one end close to the groove 111 .

[0040] With such a configuration, when initially installing the plowshare tip 12, the connecting block 21 is placed in the groove 111, the first guide surface 213 is abutted against the second guide surface 231, and the pin 23 moves in a direction away from the connecting block 21 under the action of the first guide surface 213 and the second guide surface 231. The spring 25 is compressed, the first guide surface 213 is disengaged from the second guide surface 231, and the pin 23 is abutted against the side wall of the connecting block 21. The connecting block 21 continues to be moved until the pin 23 is snapped into the slot 211 under the action of the spring 25, completing the initial installation. Therefore, with the configuration of the first guide surface 213 and the second guide surface 231, when the user installs the plowshare tip 12, he only needs to move the connecting block 21 to complete the initial installation. The operation is simple and convenient, and the first threaded hole 113 is made to correspond to the second threaded hole 212, which facilitates the installation and fixation of the fixing component 30.

[0041] Optionally, in some embodiments, see Figures 2 to 3 The shock absorbing pad 22 is arranged on the side wall of the groove 111 away from the connecting block 21 , and the shock absorbing pad 22 abuts between the connecting block 21 and the inner wall of the groove 111 .

[0042] With such an arrangement, when the user uses the plowshare to plow the land, the agricultural machine is likely to drive the plowshare tip 12 to vibrate through the plowshare body 11. The shock-absorbing pad 22 is arranged between the plowshare tip 12 and the inner wall of the groove 111 to absorb the vibration potential energy of the plowshare body 11. When the plowshare is plowing the land, if the plowshare tip 12 hits a hard object, it will also vibrate. The plowshare tip 12 and the shock-absorbing pad 22 are against each other to absorb the vibration potential energy of the plowshare tip 12.

[0043] Optionally, in some embodiments, see Figures 2 to 3 One end of the pin shaft 23 away from the groove 111 extends to the outside of the plowshare body 11 and is fixedly connected with a slide button 26 . A notch 27 is formed on one side of the slide button 26 close to the plowshare body 11 .

[0044] With such a configuration, when the plowshare tip 12 needs to be removed, the fixing assembly 30 is removed, the slide button 26 is held and abutted against the side wall of the recess 27, and the slide button 26 is moved away from the plowshare body 11 until the pin shaft 23 is disengaged from the slot 211, and the user can easily remove the plowshare tip 12 from the recess 111; therefore, the configuration of the slide button 26 makes it convenient for the user to pull the pin shaft 23 and remove the plowshare tip 12; the configuration of the recess 27 enables the user to pull the slide button 26 by abutting force rather than static friction force, and the operation is more labor-saving and quick.

[0045] Optionally, in some embodiments, see Figure 1 to Figure 2 A plurality of third threaded holes 114 are provided in the middle of the plowshare body 11 .

[0046] With such arrangement, when installing the plowshare, the plowshare is moved so that the third threaded hole 114 is aligned with the threaded notch of the agricultural machine, and the plowshare can be installed on the agricultural machine by screws to work. Therefore, the arrangement of the third threaded hole 114 makes it convenient for the user to install the plowshare.

[0047] Optionally, in some embodiments, see Figure 1 to Figure 2 The plowshare tip 12 is arranged on both sides of the plowshare body 11, the tip of the plowshare tip 12 is conical, and an oblique cut 121 is obliquely opened at the edge of the tip of the plowshare tip 12.

[0048] With such a configuration, when the user uses the plowshare to plow the land, the conical tip of the plowshare 12 can assist the user to better penetrate the soil layer for plowing, and the configuration of the oblique cut 121 can make the plowshare 12 further penetrate the soil, achieving a good land grooving effect. The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
