Description

Technical Field

[0001] This application relates to the technical field of agricultural machinery, and in particular to a front-mounted hard rock detection structure for agricultural machinery. Background Technology

[0002] Small agricultural tillers are widely used in complex terrains such as mountainous and hilly areas, and their blade designs need to be adapted to tillage needs such as loosening and breaking up soil.

[0003] Traditional agricultural tillers have blades that come into direct contact with the ground. When operating in areas with many stones, the blades are prone to hard collisions with surface or shallow stones, causing the blades to curl or crack.

[0004] Because traditional agricultural tillers lack effective stone avoidance mechanisms, frequent hard contact significantly shortens the blade life and increases maintenance costs. Utility Model Content

[0005] To reduce the direct contact between tillage machine blades and surface and shallow stones, thereby reducing blade wear, this application provides a front-mounted hard stone detection structure for tillage.

[0006] The pre-positioned hard rock detection structure for agricultural land provided in this application adopts the following technical solution:

[0007] A front-mounted hard rock detection structure for agricultural use includes a guide-type rock detection mechanism mounted on the machine body and located in front of the blade. The rock detection mechanism guides rocks on the soil surface in front of the blade and those partially embedded in the soil to both sides of the blade. The rock detection mechanism includes:

[0008] Mounting bracket, which is rotatably mounted on the machine body;

[0009] The detector plates are arranged on both ends of the same side of the mounting frame. The two sets of detector plates are close to each other on the side away from the mounting frame and connected to each other on the side away from the blade to form an A-shaped structure. The two sets of detector plates are used to guide the soil surface in front of the blade and some stones embedded in the soil to both sides of the blade.

[0010] An adjustment component is mounted on the machine body. The adjustment component is used to adjust the installation angle of the mounting bracket and the depth to which the front end of the probe is inserted into the ground.

[0011] By adopting the above technical solution, before the tiller is started, the installation angle of the mounting frame can be adjusted by adjusting the components to adjust the depth of the probe tip inserted into the soil layer. When the tiller moves forward, the A-shaped structure composed of two sets of probes facilitates the guidance of the soil surface and shallow stones to both sides of the blade, reducing the direct contact between the tiller blade and the surface and shallow stones, thereby reducing the blade wear rate.

[0012] Furthermore, the detector plate has multiple sets of through holes, which allow soil and rocks with a diameter smaller than the through holes to pass through the detector plate.

[0013] By adopting the above technical solution, the through holes of the detector plate allow small-volume soil and rocks to pass through, reducing the force exerted on the detector plate by the accumulation of small-volume soil and rocks, and reducing the resistance to the forward movement of the agricultural machinery.

[0014] Furthermore, the detector plates are tilted, and the distance between the two sets of detector plates on the side closer to the ground is greater than the distance on the side farther from the ground. The tilted detector plates facilitate the removal of stones partially embedded in the soil layer.

[0015] By adopting the above technical solution, the detector plate is set at an angle so that when the agricultural machine moves forward, the angled detector plate separates upward, prying up and removing some stones embedded in the soil layer, thus reducing the probability of shallow soil stones getting stuck.

[0016] Furthermore, the adjustment component includes:

[0017] An adjusting gear is rotatably mounted on the machine body via a rotating shaft.

[0018] An arc-shaped rack is mounted on a mounting frame and meshes with an adjusting gear. The adjusting gear drives the mounting frame to rotate via the arc-shaped rack.

[0019] A drive unit, which is mounted on the machine body and is used to drive the adjustment gear to rotate.

[0020] By adopting the above technical solution, the driving component drives the adjusting gear to rotate, which in turn drives the arc rack to move, thereby achieving precise control of the mounting bracket angle and ensuring that the insertion depth of the front end of the probe is adjustable to adapt to different soil hardness and rock distribution density.

[0021] Furthermore, the driving element includes:

[0022] A worm gear, which is mounted on a rotating shaft;

[0023] The worm gear is rotatably mounted on the machine body and meshes with the worm wheel. The worm wheel and the worm gear have a self-locking property and only the worm gear can drive the worm wheel to rotate.

[0024] A turntable is rotatably mounted on the machine body and connected to a worm gear; the turntable is used to drive the worm gear to rotate.

[0025] By adopting the above technical solution, the self-locking design of the worm gear prevents the angle from shifting due to tillage vibration, ensuring the stability of the working angle of the probe after adjustment, while the turntable is easy to operate manually.

[0026] Furthermore, two sets of adjusting gears and arc-shaped racks are symmetrically arranged on both sides of the worm gear, with the two sets of arc-shaped racks located on both sides of the mounting frame.

[0027] By adopting the above technical solution, two sets of adjusting gears and arc racks are symmetrically arranged to balance the forces on both sides of the mounting frame, avoid skewness or jamming caused by unilateral transmission, and enhance the stability and reliability of the adjustment process.

[0028] Furthermore, the mounting bracket is provided with a connecting plate for connecting two sets of arc-shaped racks, and the bottom of the connecting plate is provided with a snap-fit ​​groove to facilitate snapping the arc-shaped racks.

[0029] By adopting the above technical solution, the connection plate and the snap-fit ​​groove design realize the synchronous linkage of the two sets of arc-shaped racks, prevent the racks from misaligning during the adjustment process, and further improve the structural stability of the mounting frame when it rotates.

[0030] Furthermore, auxiliary guide wings are provided on both sides of the mounting frame, which are used to expand the dispersion range of the stones.

[0031] By adopting the above technical solution, the auxiliary guide wing further disperses the stones that have been guided to both sides, preventing the stones from bouncing back or accumulating on the sides of the aircraft, expanding the dispersion range, and providing secondary protection.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] By rotating the turntable, the worm gear meshes with the worm wheel, which in turn drives the adjusting gear and the arc rack on the mounting frame to adjust the angle of the probe tip's insertion depth into the soil. The self-locking property of the worm wheel and worm gear ensures that the angle is stable after adjustment. When the tiller moves forward, the A-type structure composed of two sets of probes facilitates the guidance of soil surface and shallow stones to both sides of the blade. At the same time, the through holes on the probe allow small-volume soil and stones to pass through to reduce resistance. Combined with the auxiliary guide wings on both sides, the stone dispersion range is further expanded, reducing the direct contact between the tiller blade and surface and shallow stones, thereby reducing the blade wear rate.

[0039] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0040] This application discloses a front-mounted hard rock detection structure for agricultural use.

[0041] Reference Figure 1 The front-mounted hard rock detection structure for farming includes a guide-type stone detection mechanism 2 set on the body 1 and located in front of the blade 11. The stone detection mechanism 2 is used to guide stones on the soil surface in front of the blade 11 and partially embedded in the soil to both sides of the blade 11.

[0042] Reference Figure 1 The stone detection mechanism 2 includes a mounting frame 21 and a detection plate 22. The mounting frame 21 is rotatably mounted on the front end of the machine body 1. The detection plate 22 is fixedly mounted on the side of the mounting frame 21 away from the machine body 1. Two sets of detection plates 22 are fixedly mounted on the mounting frame 21. The two sets of detection plates 22 are located at opposite ends on the same side of the mounting frame 21 and are symmetrically installed. The two sets of detection plates 22 are close to each other on the side away from the mounting frame 21 and are fixed by welding on the side away from the blade 11, thus forming an A-shaped structure. When the tiller moves forward, the two sets of detection plates 22 guide the stones on the soil surface in front of the blade 11 and some stones embedded in the soil to both sides, and finally guide them to both sides of the blade 11, reducing the probability of damage to the blade 11 by stones.

[0043] Reference Figure 1 In order to improve the guiding effect of the detector plate 22 on the stones, multiple sets of through holes are opened at intervals on the detector plate 22. The multiple sets of through holes make it easier for soil and stones with a diameter smaller than the passing soil and stones to pass through the detector plate 22, thereby facilitating the passage of small soil and stones and reducing the force of soil and stones on the detector plate 22 when the agricultural machine moves forward; the detector plate 22 in this embodiment is a grid structure.

[0044] Reference Figure 1 Since some stones are embedded in the soil, the detector plate 22 is tilted to facilitate the removal of the stones embedded in the soil. The distance between the two sets of detector plates 22 on the side closer to the ground is greater than the distance on the side farther from the ground. This allows the tiller to apply an upward force to the stones when it moves forward, making it easier to detect and remove the stones embedded in the soil.

[0045] Reference Figure 2The stone detection mechanism 2 also includes an adjustment component 3, which is mounted on the body 1. The adjustment component 3 is used to adjust the installation angle of the mounting frame 21, thereby adjusting the depth of the front end of the detection piece 22 inserted into the ground. The adjustment component 3 includes an adjustment gear 31, an arc rack 32, and a drive component 4. The adjustment gear 31 is rotatably mounted on the body 1 via a rotating shaft. The arc rack 32 is fixedly mounted on the mounting frame 21 and meshes with the drive gear. When the adjustment gear 31 rotates, it meshes with the arc rack 32, thereby driving the mounting frame 21 to rotate on the body 1.

[0046] Reference Figure 2 and Figure 3 The driving component 4 is mounted on the machine body 1. The driving component 4 drives the adjusting wheel to rotate. The driving component 4 includes a worm gear 41, a worm 42, and a turntable 43. The worm gear 41 is fixedly mounted on the rotating shaft and drives the rotating shaft to rotate, thereby driving the adjusting gear 31 to rotate. The worm 42 is rotatably mounted on the machine body 1 and meshes with the worm gear 41. The worm gear 41 and worm 42 have a self-locking property, ensuring that only the worm 42 can drive the worm gear 41 to rotate. The turntable... The turntable 43 is rotatably mounted on the machine body 1. The turntable 43 is fixedly connected to the worm gear 42. The turntable 43 is used to drive the worm gear 42 to rotate. When it is necessary to adjust the installation angle of the mounting bracket 21, the turntable 43 is rotated. Through the transmission of the worm wheel 41 and the worm gear 42, the adjusting gear 31 is driven to rotate, which in turn drives the sliding rack to move, thereby realizing the adjustment of the angle of the mounting bracket 21. At the same time, the self-locking property between the worm wheel 41 and the worm gear 42 prevents the mounting bracket 21 from moving back, thereby improving the installation stability of the mounting bracket 21.

[0047] Reference Figure 2 and Figure 4 To improve the stability of the mounting frame 21, two sets of arc-shaped racks 32 and adjusting gears 31 are provided on the mounting frame 21. The two sets of arc-shaped racks 32 and adjusting gears 31 are symmetrically installed on both sides of the worm gear 41. The two sets of arc-shaped racks 32 are located on both sides of the mounting frame 21. At the same time, a connecting plate 5 for connecting the two sets of arc-shaped racks 32 is fixedly installed on the mounting frame 21. The bottom of the connecting plate 5 is provided with a snap-fit ​​groove to facilitate the snap-fit ​​fixing of the arc-shaped racks 32. The connecting plate 5 is slidably connected to the machine body 1. The worm gear 41 drives the two sets of adjusting gears 31 to rotate simultaneously, which in turn drives the two sets of arc-shaped gears to move simultaneously, ultimately improving the rotational stability of the mounting frame 21.

[0048] Reference Figure 1Auxiliary guide wings 6 are fixedly installed on both sides of the mounting frame 21. The auxiliary guide wings 6 are fixedly connected to the detector plate 22 on the side near the mounting frame 21. The auxiliary guide wings 6 are tilted and further guide the stones pushed out by the detector plate 22 away from the side wall of the body 1. The dispersion range of the stones is expanded by two sets of symmetrically installed auxiliary guide wings 6.

[0049] The working principle of this application embodiment is as follows:

[0050] By rotating the turntable 43, the worm gear 42 is driven to mesh with the worm wheel 41, which in turn drives the adjusting gear 31 to work in conjunction with the arc rack 32 on the mounting frame 21. This allows for adjustment of the angle at which the front end of the probe 22 is inserted into the soil. The self-locking property of the worm wheel 41 and worm gear 42 ensures that the angle is stable after adjustment. When the tiller moves forward, the A-shaped structure composed of the two sets of probes 22 facilitates the guidance of the soil surface and shallow stones to both sides of the blade 11. At the same time, the through holes on the probe 22 allow small-volume soil and stones to pass through to reduce resistance. In conjunction with the auxiliary guide wings 6 on both sides, the stone dispersion range is further expanded, reducing the direct contact between the tiller blades and surface and shallow stones, thereby reducing the blade wear rate.

[0051] 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.
