Description

Technical Field

[0001] The utility model relates to the technical field of towing equipment, in particular to an agricultural machinery towing device. Background Art

[0002] Agricultural machinery refers to various machines used in the production processes of crop planting and animal husbandry, as well as in the processing of agricultural and livestock products. Agricultural machinery can effectively improve the efficiency of agricultural production. Agricultural machinery often needs to be towed when in use.

[0003] For example, Chinese patent application number CN202221557748.8 discloses a rear-mounted trailer for agricultural machinery. Specifically, the upper plate and the lower plate are combined to form a C-shaped structure. The Liu Yong connecting screw secures the two together. The rear trailer is fixed to the connecting screw so that the rear trailer is fixed to the middle position of the C-shaped structure by the connecting screw. The detection port of the detection mechanism faces the middle of the C-shaped structure. The trailer is monitored in real time by a monitoring camera, and the monitoring data is fed back to the vehicle controller through a wireless transmission module, so that the user can quickly know the situation of the trailer in the cab when the agricultural machinery is towing. However, the following technical problems exist:

[0004] Due to the unevenness of the fields, vibrations will be generated during the operation of agricultural machinery. The vibrations will also cause the connecting screw to separate from the nut, causing the towed agricultural machinery to fall off. Existing agricultural machinery is prone to generate a lot of dust during field work. The dust easily adheres to the lens of the surveillance camera, causing the driver to often stop and wipe it. Therefore, the screw detection operation is relatively cumbersome and has low practicality. Utility Model Content

[0005] To this end, the utility model provides an agricultural machinery towing device to solve the problem of complicated screw detection operation in the prior art.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] An agricultural machinery towing device includes a mounting plate;

[0008] A fixing block is installed at one end of the mounting plate, and a limiting component is installed at one end of the fixing block.

[0009] The fixing block includes a battery, a first fixing block is installed at one end of the fixing block, a second bolt is installed at the middle of the first fixing block, and the fixing block includes a transmission line, one end of the transmission line is connected to an alarm light.

[0010] The limiting assembly includes a second fixing block for cooperating with two pairs of bolts to limit the fixing blocks. The lower end of the second fixing block is installed with a first conductive block, and the first conductive block is connected to the second fixing block.

[0011] An external threaded tube is installed at the lower end of the second fixing block, a stopper is installed at the upper end of the external threaded tube, and a second conductive block for cooperating with the first conductive block to control the alarm light to sound an alarm is installed at the upper end of the stopper.

[0012] Furthermore, a connecting block is installed at one end of the mounting plate, and reinforcing ribs are installed at the upper and lower ends of the connecting block. Adjustment grooves are opened at the upper and lower ends of the mounting plate, and bolt three is installed in the groove cavity of the adjustment groove.

[0013] Furthermore, a mounting groove for limiting the battery is processed in the middle of the fixing block, a step groove is processed at the upper end of the groove cavity of the mounting groove, and a sealing cover is installed in the groove cavity of the step groove.

[0014] Furthermore, a bottom cover is installed at the bottom end of the externally threaded tube, and a spring for pushing the stopper upward is installed at the lower end of the inner cavity of the externally threaded tube.

[0015] Furthermore, a threaded hole for limiting the position of the second bolt is processed in the middle of the second fixing block.

[0016] The utility model has the following advantages:

[0017] When installing agricultural machinery, the connecting head of the agricultural machinery is placed between the first fixed block and the second fixed block. Bolt 2 passes through the first fixed block and the connecting head of the agricultural machinery and is finally screwed into the cavity of the threaded hole to fix the agricultural machinery. The bottom end of bolt 2 passes through the second fixed block and collides with the stop block, driving the second conductive block away from the first conductive block. If bolt 2 loosens when the agricultural machinery is working, bolt 2 moves upward, and the spring pushes the stop block upward, causing the second conductive block to collide with the first conductive block. Finally, the alarm light sounds an alarm to facilitate the driver's observation and remind the driver that bolt 2 is loose. BRIEF DESCRIPTION OF THE DRAWINGS

The fixing block 200 includes a transmission line 260, one end of which is connected to an alarm light 261. The alarm light 261 can be installed in the cab for easy observation by the driver.

[0033] A limit assembly 300 is mounted on one end of the fixing block 200. This limit assembly 300 includes a second fixing block 310 for engaging with a second bolt 250 to limit the fixing block 200. A threaded hole 311 is machined in the middle of the second fixing block 310 for limiting the second bolt 250. The second bolt 250 passes through the middle of the first fixing block 240 and screws into the groove of the threaded hole 311, thereby towing the agricultural machinery. A first conductive block 312 is fixedly mounted on the lower end of the second fixing block 310. The first conductive block 312 is connected to the battery 220, and the upper end of the first conductive block 312 is connected to the battery 220 via an electrical wire.

[0034] An externally threaded tube 320 is fixedly mounted on the lower end of the second fixed block 310, and a bottom cover 330 is mounted on the bottom end of the externally threaded tube 320. A stopper 350 is movably mounted on the upper end of the externally threaded tube 320.

The second conductive block 351 is connected to the transmission line 260. A spring 340 is mounted on the lower end of the inner cavity of the externally threaded tube 320 to push the stopper 350 upward.

[0035] When installing the agricultural machinery, the connecting head of the agricultural machinery is placed between the first fixing block 240 and the second fixing block 310. The second bolt 250 passes through the first fixing block 240 and the connecting head of the agricultural machinery and is finally screwed into the cavity of the threaded hole 311 to fix the agricultural machinery. The bottom end of the second bolt 250 passes through the second fixing block 310 and conflicts with the stop block 350, driving the second conductive block 351 away from the first conductive block 312. If the second bolt 250 becomes loose when the agricultural machinery is working, the second bolt 250 moves upward, and the spring 340 pushes the stop block 350 to move upward, causing the second conductive block 351 to conflict with the first conductive block 312. Finally, the alarm light 261 sounds an alarm, prompting the driver that the second bolt 250 is loose.
