Description

Technical Field

[0001] The utility model relates to the technical field of test racks, in particular to a test device for a rear towing mechanism of a tractor. Background Art

[0002] A tractor is a self-propelled power machine used to tow and drive working machinery to complete various mobile operations. When the tractor is used for towing, the towed equipment needs to be processed and connected to the tractor through the rear trailer.

[0003] After the tractor rear trailer is produced, it needs to be tested for its bearing capacity. Currently, most of the tests are carried out on a test stand to place a counterweight water tank installed on the rear trailer. However, the existing test stand can only place a single counterweight water tank. When multiple counterweight water tanks are stacked, the tractor has poor stability and is prone to tipping over and falling during movement. Therefore, we propose a test device for the tractor rear trailer mechanism to solve the above problem. Utility Model Content

[0027] Further, see Figure 2 and Figure 3 It can be known that the adjustment mechanism 4 includes a fixed baffle rod 41, which is fixedly connected to the top of the limiting outer frame 3, and a limiting slider 42 is inserted into the inner side of the fixed baffle rod 41, and an adjusting baffle rod 43 is fixedly connected to the outer end of the limiting slider 42. By pulling the adjusting baffle rod 43, the limiting slider 42 can slide on the inside of the fixed baffle rod 41, which is convenient for adjusting the distance between the fixed baffle rod 41 and the adjusting baffle rod 43, and is convenient for installing multiple sets of limiting mechanisms 6.

[0028] Further, see Figure 2 and Figure 3It can be known that a sliding groove compatible with the limiting slider 42 is opened on the inner side of the fixed blocking rod 41, a limiting bolt 44 is inserted into the outer thread of the fixed blocking rod 41, and a groove compatible with the limiting bolt 44 is opened inside the limiting slider 42. The limiting bolt 44 can be inserted into the groove through the groove opened inside the limiting slider 42, which facilitates the function of the limiting slider 42.

[0029] Further, see Figure 2 and Figure 3 It can be known that the inner side of the adjustment stop rod 43 is fixedly connected with a reinforcement rod 45, and multiple groups of reinforcement rods 45 are arranged at equal distances. The stability of the adjustment stop rod 43 can be increased by multiple groups of reinforcement rods 45.

[0030] Further, see Figure 3 and Figure 4 It can be known that the connecting mechanism 5 includes a plug-in column 51, the outer sides of the fixed baffle rod 41 and the adjustable baffle rod 43 are fixedly connected with the plug-in column 51, and a plug-in slider 52 is inserted in the plug-in column 51, and the outer end of the plug-in slider 52 is fixedly connected with a connecting slider 53. By inserting the plug-in slider 52 in the plug-in column 51, the limiting mechanism 6 can be easily installed.

[0031] Further, see Figure 3 and Figure 4 It can be known that the limiting mechanism 6 includes a locking plate 61, a connecting slider 53 and a sliding connection with the locking plate 61, and a pushing screw 62 is threadedly inserted on both sides of the locking plate 61, and the end of the pushing screw 62 is connected to a pressure cross plate 63 through a bearing. A groove matching the pressure cross plate 63 is provided on the inner wall of the locking plate 61. Through the pushing screw 62 threadedly inserted on both sides of the locking plate 61, the pressure cross plate 63 can be pushed to move in the locking plate 61 when the pushing screw 62 is rotated, which facilitates the function of squeezing the limiting counterweight water tank 7.
