Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Example 1
[0027] A universal quick docking device for agricultural machinery, such as Figures 1-6 As shown, the device includes:
[0028] The equipment includes a tool fixing plate 1, a tool support frame 2, and a tool guide mounting plate 3. The tool support frame 2 is fixedly connected to the front side of the tool fixing plate 1, and the tool guide mounting plate 3 is symmetrically connected to both sides of the tool support frame 2. The tool fixing plate 1 consists of a front fixing plate 101, a left fixing plate 102, and a right fixing plate 103. The front ends of the front plate 101 are welded to the front ends of the left plate 102 and the right plate 103, respectively, and the front plate 101, left plate 102 and right plate 103 form a U-shaped structure after being fixedly connected. Square steel is welded on the top of the front plate 101, left plate 102 and right plate 103, and the extension direction of the square steel corresponds one-to-one with the front plate 101, left plate 102 and right plate 103, so as to further reinforce the front plate 101, left plate 102 and right plate 103 and ensure the firmness of the connection.
[0029] The machine support frame 2 includes an upper hollow cup 201, a support leg steel bar 202, a support leg connecting pipe 203, a support leg plate 204, and a support leg connecting lug 205. The upper hollow cup 201 is a hollow shaft structure, with its internal shaft diameter corresponding to the pin holes of the support leg plate 204. When the central axis of the hollow shaft of the upper hollow cup 201 coincides with the common central axis of the two pin holes of the support leg plate 204, a pin is inserted, achieving a movable connection between the upper hollow cup 201 and the support leg plate 204. The bottom center of the upper hollow cup 201 is welded and fixed to the upper end of the support leg steel bar 202, and the top center of the support leg connecting pipe 203 is welded and fixed to the lower end of the support leg steel bar 202. The length of the support leg steel bar 202 is greater than the height of the front plate 101 of the fixed plate. The upper hollow cup 201, the support leg steel bar 202, and the support leg connecting pipe 203 are fixedly connected to form a whole. The bottom of the support foot plate 204 is symmetrically welded and fixed to the upper end of the front plate 101 of the fixing plate. The support foot plate 204 has an L-shaped structure, and its upper end is fan-shaped with a through-hole for installing the upper hollow cup 201, indirectly connecting the support foot steel bar 202, and indirectly realizing the installation and removal of the machine support frame 2 at any time. The side wall of the support foot connecting ear 205 is fixed to the front plate 101 of the fixing plate by a nut. It is located directly below the support foot plate 204. A through hole is provided in the center of its upper surface for inserting the support foot steel bar 202 to ensure the fixation of the machine support frame 2. When the implement needs to be connected to the power platform for operation, the implement support frame 2 is removed from the front plate 101 of the device fixing plate and placed on the ground. It is then fixedly connected to the towed agricultural implement (by rope, welding, or bolts) to support the towed agricultural implement and prevent it from tipping over during connection. After the towed agricultural implement is properly connected and fixed, the implement support frame 2 is separated and retracted. The through-hole of the upper hollow cup 201 is located in the middle of the pin hole of the support foot plate 204, and the central axis of the through-hole of the upper hollow cup 201 and the common central axis of the two pin holes of the support foot plate 204 are kept coincident. The pin is then inserted to fix the implement support frame 2 and prevent it from affecting the operation of the implement.
[0030] The tool guide mounting plate 3 includes two upper guide mounting plates 301, two lower guide mounting plates 302, and two guide mounting limiting plates 303. The upper and lower ends of the guide mounting limiting plates 303 are fixedly connected to the right side walls of the upper guide mounting plates 301 and the lower guide mounting plates 302, respectively. The fixedly connected upper guide mounting plates 301, lower guide mounting plates 302, and guide mounting limiting plates 303 form a U-shaped structure, and there are two of them. The front side wall of one set of fixedly connected upper guide mounting plates 301, lower guide mounting plates 302, and guide mounting limiting plates 303 is welded and fixed to the left plate 102 of the fixed plate. The rear side wall of the other fixedly connected upper guide mounting plates 301, lower guide mounting plates 302, and guide mounting limiting plates 303 is welded and fixed to the right plate 103 of the fixed plate, corresponding to the position of the set of fixed upper guide mounting plates 301, lower guide mounting plates 302, and guide mounting limiting plates 303 on the left plate 102. Bolt holes are provided on the upper plate 301 and lower plate 302 of the guide mounting plate for inserting U-bolts. The power platform frame also has similar bolt holes. During docking, after the power platform frame moves to the position of the guide mounting limit plate 303, the U-bolts are inserted into the bolt holes on the upper plate 301 and lower plate 302 of the guide mounting plate and the bolt holes on the power platform frame for fixing, thus securing the power platform to the machine. Simultaneously, reinforcing ribs are welded to both the upper plate 301 and lower plate 302 of the guide mounting plate to strengthen the structure and ensure a firm and reliable installation.
[0031] The specific usage method of the above-mentioned general quick docking device for agricultural machinery is as follows:
[0032] When a towed agricultural implement (the same as the towed agricultural implement in Comparative Example 1) needs to be connected to a power platform, the towed agricultural implement is fixed between the front plate 101, left plate 102, and right plate 103 of the docking device using ropes, welding, or bolts, thus securing the docking device to the towed agricultural implement. Simultaneously, the pins inserted into the through-hole of the upper hollow cup 201 and the pin holes of the support foot plate 204 of the docking device are removed. The upper hollow cup 201, the support foot steel bar 202, and the support foot connecting pipe 203 are then lowered through the through-hole of the support foot connecting ear 205, ensuring that the support foot connecting pipe 203 contacts the ground and is fixedly connected to the towed agricultural implement (using ropes, welding, or bolts) to support the towed agricultural implement and prevent it from tipping over during docking. The fixed docking device and the towing agricultural implement are moved. After the guide installation limit plate 303 of the docking device is moved to the power platform frame, the U-bolts are inserted into the bolt holes on the upper plate 301 and the lower plate 302 of the guide installation plate and the bolt holes on the power platform frame and fixed, thus indirectly realizing the fixation of the towing agricultural implement and the power platform.
[0033] When the towed agricultural implement is fixed to the power platform and put into operation, the implement support frame 2 is separated from the towed agricultural implement and moved upward. The through-hole of the upper hollow cup 201 is positioned in the middle of the pin hole of the support foot plate 204, and the central axis of the through-hole of the upper hollow cup 201 and the common central axis of the two pin holes of the support foot plate 204 are kept coincident. The pin is inserted to connect the implement support frame 2 and the device fixing plate 1, so as to prevent it from affecting the operation of the implement.
[0034] After the towed agricultural implement has finished working, remove the U-bolts inserted in the bolt holes on the upper plate 301 and the lower plate 302 of the guide mounting plate and the bolt holes on the frame of the power platform to separate the docking device from the power platform; untie the ropes and use thermal cutting or remove the bolts that fix the towed agricultural implement to separate the docking device from the towed agricultural implement.
[0035] Comparative Example 1
[0036] Existing towed agricultural implements (such as the Dongfanghong 1LF-435 hydraulic reversible plow from China YTO Group, which uses a three-point suspension and manual locking pins to adapt to LX / LP series tractors) mainly rely on adjusting the position of the tow bar and the position of the connecting locking pin to connect the towed agricultural implement to the tractor. This requires a high level of technical skill and multiple adjustments and confirmations of the connection position to ensure the reliability of the connection. The entire connection process is time-consuming and labor-intensive, and cannot meet the requirements of rapid connection operations.
[0037] Compared with the prior art, this utility model includes a tool guide mounting plate, which can quickly confirm the installation position of the tool and the power platform. At the same time, there is a tool support frame to ensure that the tool does not tip over during installation, which solves the problems of inaccurate positioning and low efficiency in the connection of the prior art.
[0038] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above content. Therefore, the scope of protection of the present invention should be defined by the appended claims.
