Description

Technical Field

[0001] The present application relates to the field of iron hoes, and in particular to an iron hoe. Background Art

[0002] A harrow is a common agricultural tool used to level and loosen the soil. In modern agricultural farming, operators usually use mechanized equipment to plow and harrow the land, and then use harrows to break up and turn the soil on some lands that still have large clods or where mechanical equipment is difficult to work, so as to make the soil looser and more breathable, which is more conducive to the growth of crops. In actual operations, when operators use harrows to level and loosen the land, the teeth are often easily worn, bent or broken due to collisions with hard stones, clods and other objects in the soil. In addition, depending on the softness of the cultivated land, the terrain and other conditions, the harrows are often installed on different parts of the land. The tooth density has certain requirements. Under the existing technology, operators usually configure multiple different types of iron harrows so that when the teeth are damaged or the cultivated land is replaced, other iron harrows can be replaced to continue working. This treatment method will cause multiple iron harrows except the working iron harrow to be idle, which is more resource-intensive. In addition, when the iron harrow is damaged or unsuitable, it takes a certain amount of time for the operator to travel back and forth between the cultivated land and the tool storage place for replacement, which causes certain inconveniences to agricultural farming work using iron harrows. In summary, in order to solve the above problems, the inventor proposes an iron harrow. Utility Model Content

First, the control frame can be toggled to make the block slide out of the limit groove in the sliding module along the guide bar. At this time, the limit ring squeezes the elastic member, so that the elastic member is compressed along the positioning rod. Then the damaged teeth can be removed from the iron harrow, and then new teeth can be inserted into the iron harrow. Then the control frame is released, and the elastic member is stretched through the limit ring to drive the block to be inserted into the limit groove, thereby fixing the teeth to the iron harrow. In order to complete the replacement of a single tooth, when the operator needs to adjust the tooth density of the iron harrow due to the softness of the cultivated land, the terrain and other conditions, he can first push the push rod, then rotate the screw rod, insert the screw rod into the push rod, and fix the push rod. At this time, the push plate pushes the control plate to make the block away from the limit groove, and the elastic part is compressed at this time, and then any tooth can be easily removed and assembled. When the adjustment is completed, the screw rod is rotated out of the push rod, and the elastic part stretches the drive block to insert the limit groove, so that the adjustment of the tooth density installed on the iron harrow is completed. By setting up the assembly mechanism, the processing method under the existing technology is improved to a certain extent, which is more resource-consuming, and when the iron harrow is damaged or unsuitable, the operator needs to travel back and forth between the cultivated land and the tool storage place to replace it, which also takes a certain amount of time, causing certain inconvenience to the agricultural farming work using the iron harrow.

The inner wall of 04 is engaged with the block 503, one end of the block 503 is fixedly connected to the limit ring 505, the limit ring 505 is fixedly connected to the side close to the sliding module 502 with an elastic member 506, the other end of the elastic member 506 is fixedly connected to the sliding module 502, the upper surface of the block 503 is fixedly connected to the control frame 507, the upper end of the control frame 507 is slidably connected to the cover plate 3, the other end of the block 503 is fixedly connected to the control board 508, the inside of the iron harrow 1 is slidably provided with a push rod 509, the arc surface of the push rod 509 corresponding to the position of the control board 508 is fixedly connected with a push plate 510, and the push plate 510 is abutted against the control board 508. The purpose is achieved that when the operator uses the iron harrow to level and loosen the land, the teeth 2 are worn, bent or broken due to collision with hard stones, clods and other objects in the soil, and the teeth 2 need to be adjusted according to the softness of the cultivated land, the terrain and other conditions. With the help of the assembly mechanism 5, the position of the push rod 509 or the control frame 507 can be moved to make the block 503 slide out of the limit groove 504, thereby achieving the purpose of adjusting the teeth 2 according to the actual situation, thereby improving the processing method under the prior art to a certain extent, which is more resource-consuming. When the iron harrow is damaged or unsuitable, it takes a certain amount of time for the operator to travel back and forth between the cultivated land and the tool storage place for replacement, which causes certain inconvenience to the agricultural farming work using the iron harrow. The position corresponding to the block 503 inside the iron harrow 1 is fixedly connected with a guide bar 511, and the surface of the guide bar 511 is slidably connected to the block 503. The sliding track of the block 503 is constrained, so that the block 503 can be better inserted into the limit groove 504, and then the teeth 2 are limited. The elastic member 506 is internally slidably connected with a positioning rod 512, and the arc surface of the positioning rod 512 is slidably connected with the limit ring 505. One end of the positioning rod 512 is fixedly connected with the limit block 501, and the other end of the positioning rod 512 is fixedly connected with the sliding module 502. The elastic force direction of the elastic member 506 is limited, so that the elastic member 506 drives the block 503 to insert into the limit groove 504 to fix the teeth 2 more firmly. The surface of the iron hoe 1 is fixedly connected with a mounting frame 513, and the surface of the mounting frame 513 is threadedly inserted with a screw 514, and one end of the screw 514 continuously threads through the iron hoe 1 and the push rod 509.The operator can fix the position of the push rod 509, so that it is more convenient to insert the teeth 2 into the iron hoe 1 when assembling the teeth 2 in batches. One end of the push rod 509 is fixedly connected to a handle 515, and the cross-section of the handle 515 is circular. The effect of making it easier for the operator to move the position of the push rod 509 is achieved, thereby making it more convenient to operate the assembly mechanism 5 to assemble the teeth 2. The adjusting device 6 includes an adjusting cylinder 61, the inner wall of the adjusting cylinder 61 is slidably connected to the rod 4, the arc surface of the adjusting cylinder 61 is fixedly connected with a U-shaped plate 62, the surface of the U-shaped plate 62 is slidably inserted with an insertion rod 63, one end of the insertion rod 63 slides through the adjusting cylinder 61, and the arc surface of the rod 4 is evenly provided with a plurality of insertion holes 64, the insertion holes 64 are adapted to the shape and size of the insertion rod 63, the inner wall of the insertion hole 64 is slidably connected to the insertion rod 63, the other end of the insertion rod 63 is fixedly connected with a fixing block 65, the surface of the fixing block 65 is abutted with a rubber band 66, and the two ends of the rubber band 66 are fixedly connected to the adjusting cylinder 61. When the operator needs to use the hoe to level and loosen the land, the relative position of the adjusting tube 61 and the rod 4 can be adjusted by moving the position of the insert rod 63 with the help of the adjusting device 6, so as to adjust the combined length of the rod 4 and the adjusting tube 61, so that the operator can adjust the length of the gripping part of the hoe according to actual needs, so that the operator can better exert force to level and loosen the land. The surface of the fixed block 65 is provided with a limiting groove 67, and the inner wall of the limiting groove 67 abuts against the rubber band 66. The position of the rubber band 66 is limited, so that the rubber band 66 can better drive the insert rod 63 to be inserted into the jack 64 through the fixed block 65, so as to fix the position of the adjusting tube 61 more firmly.

[0022] The working principle is as follows: when the operator uses the iron harrow to level and loosen the soil, the teeth 2 are worn, bent or broken due to collision with hard stones, clods and other objects in the soil. When the teeth 2 need to be replaced, the control frame 507 can be firstly toggled to make the block 503 slide out of the limit groove 504 in the sliding module 502 along the guide bar 511. At this time, the limit ring 505 squeezes the elastic member 506 so that the elastic member 506 is compressed along the positioning rod 512. Then the damaged teeth 2 can be removed from the iron harrow 1, and then the new teeth 2 can be inserted into the iron harrow 1. Then the control frame 507 is released, and the elastic member 506 is stretched through the limit ring 505 to drive the block 503 to be inserted into the limit groove 504, thereby fixing the teeth 2 in the iron harrow 1. To complete the replacement of a single tooth 2, and when the operator needs to adjust the density of the teeth 2 installed on the iron harrow 1 due to the softness of the cultivated land, the terrain and other conditions, the operator can first push the push rod 509, and then rotate the screw 514, insert the screw 514 into the push rod 509, so as to fix the push rod 509. At this time, the push plate 510 pushes the control plate 508 to make the block 503 away from the limiting groove 504, and the elastic member 506 is compressed at this time, and then any tooth 2 can be conveniently removed and assembled. When the adjustment is completed, the screw 514 is rotated out of the push rod 509, and the elastic member 506 stretches the drive block 503 to insert the limiting groove 504, thereby completing the adjustment of the density of the teeth 2 installed on the iron harrow 1. By setting up the assembly mechanism 5, the processing method under the prior art is improved to a certain extent. It is relatively resource-consuming, and when the iron harrow is damaged or unsuitable, it takes a certain amount of time for the operator to travel back and forth between the cultivated land and the tool storage place for replacement, which causes certain inconveniences to agricultural farming work using the iron harrow.

[0023] When the operator needs to use the iron harrow to level and loosen the soil, he can first pull the fixing block 65 to move the insertion rod 63 away from the pole 4 until the insertion rod 63 is out of contact with the pole 4. At this time, the rubber band 66 is stretched in the limit groove 67, and then the adjustment cylinder 61 can be slid to adjust the relative position of the adjustment cylinder 61 and the pole 4 according to the actual situation. When the adjustment is completed, the fixing block 65 is released, the rubber band 66 contracts, and the insertion rod 63 is driven to be inserted into the socket 64 to fix the position of the adjustment cylinder 61, thereby adjusting the combined length of the pole 4 and the adjustment cylinder 61. By setting the adjustment device 6, the operator can adjust the length of the gripping part of the iron harrow according to actual needs, so that the operator can better exert force to level and loosen the soil. 。
