Through setting up fixing base 170 makes the one end of elasticity piece 160 that resets can be connected with fixing base 170, and the other end is connected with support piece 120, and fixing base 170 can also be regarded as the landing platform when the tractor unloads in addition and use.
As shown in fig. 2, the fixing base 170 is provided with a support wheel 171, and the support wheel 171 is in rolling connection with the bottom surface of the pedal 110. The supporting wheel 171 is additionally arranged on the fixed seat 170, so that the friction between the pedal 110 and the fixed seat 170 is changed from sliding friction to rolling friction, the magnitude of the friction force applied when the pedal 110 and the fixed seat 170 move relatively is reduced, and meanwhile, the supporting wheel 171 also plays a supporting role in supporting the pedal 110. According to an embodiment of the present invention, the supporting member 120 is installed on the bottom surface of the pedal 110 and is disposed away from the fixing base 170, so that the supporting member 120 mainly bears the pedal force of the pedal 110 away from the fixing base 170, the supporting wheel 171 mainly bears the pedal force of the side close to the fixing base 170, and the supporting member 171 and the supporting member 120 jointly support the pedal 110, thereby improving the upper limit of the force that the pedal 110 can bear, and simultaneously improving the stability of the pedal 110 when a person steps on the pedal 110.
Further, the guiding device 130 includes a guide rod 131 and a connecting frame 133 that are connected to each other, a slider 121 is disposed at one end of the supporting member 120 facing the guide rod 131, the slider 121 is provided with a through hole for the guide rod 131 to pass through, and the guide rod 131 is slidably connected to the slider 121. The guide rod 131 is slidably connected with the through hole, and on one hand, the sliding block 121 can be guided to move away from or close to the tractor along the extending direction of the guide rod 131; on the other hand, the moving direction of the sliding block 121 is limited, so that the sliding block 121 is prevented from deviating from the guide of the guide rod 131 due to lack of limit.
Furthermore, the two ends of the guide rod 131 are provided with stoppers 132, and the stoppers 132 are mounted on the connecting frame 133. The limiting blocks 132 are arranged at the two ends of the guide rod 131, so that the moving stroke of the slider 121 on the guide rod 131 is limited, the slider 121 is prevented from sliding out of the guide rod 131, the sliding connection between the slider 121 and the guide rod 131 is disabled, and the effectiveness of the guide function of the guide rod 131 on the slider 121 can be ensured by additionally arranging the limiting blocks 132.

By arranging the plurality of guide rods 131, and at least one supporting piece 120 corresponding to each guide rod 131, on one hand, the stability of the sliding of the supporting pieces 120 on the guide rods 131 is increased; on the other hand, as the number of the guide rods 131 is increased, the number of the supporters 120 is also increased corresponding to the number of the guide rods 131, so that the supporting capability of the supporters 120 for the pedal 110 is also enhanced, and the upper limit of the force that the pedal 110 can bear is increased.
In addition, a rotating arm 146 is arranged on the rotating rod 145, the rotating arm 146 and the swing arm 143 are arranged in a staggered manner along the circumferential direction of the rotating rod 145, the transmission assembly 147 comprises a connecting rope 152, a first pulley block 148 and a second pulley block 149, the connecting rope 152 is sequentially wound around the periphery of the pulleys of the first pulley block 148 and the second pulley block 149, one end of the connecting rope 152 is connected with the rotating arm 146, and the other end of the connecting rope 152 is connected with the support member 120. The swing arm 143 and the swing arm 146 are disposed in a staggered manner, so that if the length of the swing arm 146 is greater than that of the swing arm 143 and the swing arm 143 is located at the same position, the swing arm 143 cannot abut against the tractor. The first pulley block 148 and the second pulley block 149 are provided to change the direction of the force of the rotating arm 146 pulling the connecting rope 152 into the force of pulling the support 120.
As shown in fig. 1, the second pulley block 149 includes a vertically disposed mounting bracket 150 and at least two turning wheels 151 disposed on the mounting bracket 150 at intervals in a vertical direction, and an extending direction of a connection rope 152 between the turning wheel 151 near the top of the mounting bracket 150 and the support 120 coincides with a moving direction of the support 120. The reason for keeping the connection string 152 between the upper rotating wheel 151 and the support 120 in the same direction as the moving direction of the support 120 is to save more labor when pulling the support 120 to move.
Wherein, the swing arm 143 is provided with a roller 144 at an end departing from the rotating rod 145. The roller 144 is arranged at one end, away from the rotating rod 145, of the swing arm 143 so as to reduce friction force when the swing arm 143 slides relative to the tractor, and the roller 144 is additionally arranged so as to convert sliding friction into rolling friction so as to reduce friction force, so that the swing arm 143 is prevented from scratching the surface of the vehicle body.
In addition, the utility model also provides a discharging mechanism which comprises the tractor and the pedal telescopic device 10.
