Description

Technical Field

[0001] This application relates to the field of agricultural equipment, and in particular to a damper for an agricultural machine. Background Technology

[0002] A tiller is a type of agricultural machinery suitable for use on slopes, hills, and in areas where large and medium-sized agricultural machinery cannot operate. The machine itself has multiple functions; by changing different attachments, it can perform various tasks such as rotary tillage, ditching and ridging, and weeding.

[0003] Currently, when agricultural tillers perform rotary tillage, the tillage depth is usually controlled by a resistance rod. Inserting the resistance rod into the soil at different depths creates varying resistance for the tiller, thereby controlling its forward speed and the tillage time of the blades on the same soil area, thus providing auxiliary control over the tillage depth.

[0004] However, when the resistance rod is inserted into the soil, it will stick to the soil and stones. When the resistance rod is retracted later, the soil and stones will easily get stuck in the sliding connection of the resistance rod as it rises, affecting the sliding adjustment of the resistance rod. Utility Model Content

[0005] In order to improve the problem that the resistance bar easily carries soil and stones, which affects the sliding adjustment of the resistance bar, this application provides a damper for agricultural tillers.

[0006] The agricultural machinery damper provided in this application adopts the following technical solution:

[0007] A damper for an agricultural tiller includes a support, a resistance rod, a positioning element, a scraper sleeve, and a locking element. The support is mounted on the agricultural tiller, the resistance rod is slidably mounted on the support, the positioning element is mounted on the support and is used to position the resistance rod, the scraper sleeve is slidably mounted on the resistance rod, and the locking element is mounted on the support and is used to position the scraper sleeve on the support.

[0008] By adopting the above technical solution, the resistance rod is driven to slide on the support, and then the resistance rod is positioned by the positioning component. The depth of the resistance rod inserted into the soil is adjusted, thereby providing auxiliary control for different tillage depths. Before lifting the resistance rod, the positioning of the scraper sleeve on the support is unlocked by the locking component, and then the scraper sleeve is driven to slide with the resistance rod, which can scrape off the soil and stones adhering to the resistance rod, thus improving the problem that the resistance rod easily carries soil and stones, which affects the sliding adjustment of the resistance rod.

[0009] Optionally, the locking element includes a spring pin, which is disposed on the support, and the scraper sleeve has a locking groove for the spring pin to engage.

[0010] By adopting the above technical solution, when the scraper sleeve moves towards the support, the scraper sleeve first abuts against the spring pin, causing the spring pin to retract. When the scraper sleeve moves to the point where the lock groove is opposite to the spring pin, the spring pin pops out and locks into the lock groove, thus conveniently positioning the lock sleeve on the support.

[0011] Optionally, the scraper sleeve is slidably provided with an unlocking block for driving the spring pin out of the lock groove.

[0012] By adopting the above technical solution, pressing the unlocking block causes it to approach the spring pin, which in turn pushes the spring pin out of the lock groove, thus easily releasing the positioning of the scraper on the support.

[0013] Optionally, the cross-sectional dimensions of the scraper sleeve gradually decrease from near the support to far away from the support.

[0014] By adopting the above technical solution, when scraping away the soil and stones on the resistance rod, the scraper sleeve, whose cross-sectional size gradually decreases from the direction close to the support to the distance from the support, disengages from the soil and stones, making it easier to scrape the soil and stones off the resistance rod.

[0015] Optionally, the bottom of the resistance rod is bent away from the tiller.

[0016] By adopting the above technical solution, the bottom of the resistance bar, which bends away from the tiller, reduces the possibility of the resistance bar getting stuck in contact with hard objects in the soil, thus improving the resistance bar's passability.

[0017] Optionally, the positioning element includes a pin, and the resistance rod has a plurality of positioning holes spaced apart along its length. The pin is slidably inserted into the support and is used to pass through the positioning holes.

[0018] By adopting the above technical solution, the resistance rod is driven to move on the support, so that the positioning holes at different heights are aligned with the pin. Then, the pin is passed through the positioning hole, so that the height of the resistance rod can be adjusted and positioned conveniently and quickly.

[0019] Optionally, a cotter pin is provided at one end of the pin that passes through the positioning hole.

[0020] By adopting the above technical solution, after the pin passes through the positioning hole, the cotter pin passes through the end of the pin that passes through the positioning hole, reducing the possibility of the pin falling off.

[0021] Optionally, the support is hinged on the agricultural tiller.

[0022] By adopting the above technical solution, during the rotary tillage process, driving the support to rotate will cause the resistance rod to rotate relative to the tiller, thus providing auxiliary guidance for the tiller's travel direction.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By driving the scraper sleeve to slide along the resistance rod, the mud and stones adhering to the resistance rod can be scraped off, thus improving the problem that the resistance rod easily carries mud and stones, which affects the sliding adjustment of the resistance rod;

[0025] 2. When the scraper sleeve moves to the point where the lock groove is aligned with the spring pin, the spring pin pops out and engages in the lock groove, thus easily positioning the lock sleeve on the support.

[0026] 3. By driving the support to rotate, the resistance rod can be driven to rotate relative to the tiller, thus providing auxiliary guidance for the tiller's movement. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a damper for a farming machine.

[0032] Reference Figure 1 , Figure 2 The damper for the agricultural tiller includes a support 1, a resistance rod 2, a positioning element 3, a scraper sleeve 4, and a locking element 5. The support 1 is hinged to the handle side of the agricultural tiller via a hinge shaft. The resistance rod 2 slides vertically through the support 1. Multiple positioning holes 21 are spaced vertically along the resistance rod 2. The positioning element 3 is installed on the support 1 and is used to position the resistance rod 2. The positioning element 3 includes a pin 31. The pin 31 passes through the side wall of one side of the support 1, then through the positioning hole 21, and then through the side wall of the opposite side of the support 1.

[0033] Pulling out the pin 31 allows the resistance rod 2 to slide vertically on the support 1, aligning the positioning hole 21 at another height on the resistance rod 2 with the pin 31. Then, inserting the pin 31 into the support 1 and passing it through the positioning hole 21 allows the resistance rod 2 to be positioned on the support 1. This facilitates quick and easy adjustment of the height of the resistance rod 2, and allows for adjustment of the depth of insertion of the resistance rod 2 into the soil. This provides auxiliary control for different rotary tillage depths and also allows the support 1 to be rotated, enabling the resistance rod 2 to turn relative to the tiller during rotary tillage. This provides auxiliary guidance when the tiller changes direction, improving the ease of changing the tiller's travel direction.

[0034] Reference Figure 1 , Figure 2 A cotter pin 7 is inserted along the axis of the pin 31, passing through the support 1, the positioning hole 21, and then exiting the support 1. After the pin 31 is inserted into the support 1 and through the positioning hole 21 to position the resistance rod 2, the cotter pin 7 is then inserted into the pin 31, which passes through the support 1, the positioning hole 21, and then exits the support 1. This locks the pin 31 onto the support 1, reducing the possibility of the pin 31 coming off and thus improving the stability of the pin 31 in positioning the resistance rod 2.

[0035] Reference Figure 1 The bottom of the resistance bar 2 bends away from the tiller. As the tiller moves through the soil, the bottom of the resistance bar 2, which bends away from the tiller, applies downward pressure to hard objects in the soil, reducing the likelihood of the resistance bar 2 getting stuck and improving its mobility in the soil.

[0036] Reference Figure 1 The scraper sleeve 4 is slidably mounted on the resistance rod 2. The cross-sectional size of the scraper sleeve 4 gradually decreases from the direction close to the support 1 to the direction far away from the support 1. This makes it easier to scrape the soil and stones off the resistance rod 2 when the scraper sleeve 4 slides from top to bottom. The scraper sleeve 4, with its cross-sectional size gradually decreasing from the direction close to the support 1 to the direction far away from the support 1, first disengages from the soil and stones, reducing the contact area and making it easier to scrape the soil and stones off the resistance rod 2.

[0037] Reference Figure 1 , Figure 2The locking element 5 is installed on the support 1. The locking element 5 is used to position the scraper sleeve 4 on the support 1. The locking element 5 includes a spring pin 51. The spring pin 51 is installed on the support 1. A locking groove 41 is provided on the side wall of the scraper sleeve 4 near the support 1. The locking groove 41 is used for the spring pin 51 to be inserted. An unlocking block 6 is slidably installed on the scraper sleeve 4 at a position opposite to the locking groove 41. The unlocking block 6 can slide into the locking groove 41 and push the spring pin 51 out of the locking groove 41. In this embodiment, an anti-detachment block 8 is installed on the part of the unlocking block 6 located inside the scraper sleeve 4. The diameter of the anti-detachment block 8 is larger than the opening diameter of the cavity of the unlocking block 6 inserted in the scraper sleeve 4 at the end away from the spring pin 51, thereby reducing the possibility of the unlocking block 6 detaching from the scraper sleeve 4.

[0038] When the scraper sleeve 4 moves upward to reset, it first abuts against the spring pin 51, causing the spring pin 51 to retract into the support 1. When the scraper sleeve 4 continues to move upward and the spring pin 51 is aligned with the lock groove 41, the spring pin 51 then engages in the lock groove 41. During the engagement process, the spring pin 51 pushes the unlocking block 6 out of the lock groove 41, making it convenient to press the unlocking block 6 later, which can easily and quickly position the lock sleeve on the support 1. When it is necessary to unlock the scraper sleeve 4, simply press the unlocking block 6. The unlocking block 6 moves towards the spring pin 51 and pushes the spring pin 51 out of the lock groove 41, which can easily release the positioning of the scraper sleeve 4 on the support 1.

[0039] The implementation principle of the damper for a tiller in this application embodiment is as follows: When the resistance rod 2 needs to be retracted, press the unlocking block 6 to release the lock of the scraper sleeve 4, and then drive the scraper sleeve 4 to move down along the resistance rod 2. The scraper sleeve 4 can scrape off the mud and stones adhering to the resistance rod 2. Then reset the scraper sleeve 4 and lift the resistance rod 2. During the lifting process, the scraper sleeve 4 can scrape off the mud and stones adhering to the resistance rod 2 again, effectively improving the problem that the resistance rod 2 is prone to carrying mud and stones, which affects the sliding adjustment of the resistance rod 2.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
