[0032] The present invention will be described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1:

[0034] The following is combined with Figure 1-4 The present embodiment describes a hydraulically controlled grain transport vehicle, comprising: a grain tank 1, a power support 2 connected to the lower part of the grain tank 1, an input shaft 3 rotatably connected in the power support 2, the input shaft 3 can provide power for a hydraulic pump 4, the hydraulic pump 4 is connected to a pump support 5, the pump support 5 is connected to the power support 2, the oil inlet end of the hydraulic pump 4 is connected to an oil tank 6, the oil tank 6 is connected to the grain tank 1, the oil outlet end of the hydraulic pump 4 is connected to a hydraulic regulating valve 7, the hydraulic regulating valve 7 can control the oil supply of a hydraulic motor 8, the hydraulic motor 8 is connected to the grain tank 1 through a motor support, the hydraulic regulating valve 7 and the oil return end of the hydraulic motor 8 are both connected to the oil tank 6, the hydraulic motor 8 can provide power for a feeding mechanism 9 in the grain tank 1, the feeding mechanism 9 can feed material to a feeding mechanism 10, and the power of the feeding mechanism 10 is provided by the input shaft 3;

[0035] When transporting grain, fill the grain box 1 with grain. When discharging, turn on the power of the input shaft 3. The input shaft 3 provides power for the hydraulic pump 4. The hydraulic pump 4 draws oil from the oil tank 6 and injects it into the hydraulic regulating valve 7. The hydraulic regulating valve 7 is adjusted. The speed of the hydraulic motor 8 is controlled by controlling the oil supply to the hydraulic motor 8 and the oil return to the oil tank. The hydraulic motor 8 drives the feeding mechanism 9 to operate. The feeding speed is controlled by controlling the speed of the hydraulic motor 8 to control the feeding speed, thereby realizing stepless regulation. The feeding mechanism 9 feeds the grain in the grain box 1 into the feeding mechanism 10. The power of the feeding mechanism 10 is provided by the input shaft 3 to discharge the fed grain.

[0036] The oil inlet of the hydraulic pump 4 is connected to the bottom of the oil tank 6 through the oil pipe 1 11, and the oil outlet of the hydraulic pump 4 is connected to the oil inlet of the hydraulic regulating valve 7 through the oil pipe 2 12. The two oil outlets of the hydraulic regulating valve 7 are respectively connected to the oil pipe 3 13 and the oil pipe 4 4. The oil pipe 3 13 is connected to the oil inlet of the hydraulic motor 8, and the oil pipe 4 4 ​​is connected to the upper part of the oil tank 6. The oil outlet of the hydraulic motor 8 is connected to the upper part of the oil tank 6 through the oil pipe 5 15;

[0037] The input shaft 3 is connected to the shaft end of the hydraulic pump 4 through a chain drive 16;

[0038] Chain drive-16 transmission is not easy to slip.

[0039] The grain box 1 includes a frame 17 and an inner box 18. The inner box 18 is connected to the frame 17. The power bracket 2 is connected to the lower part of the frame 17. The inner box 18 is wide at the top and narrow at the bottom. The feeding mechanism 9 includes a bearing bracket 91. The bearing bracket 91 is connected to the inner surface of the frame 17. Two feeding shafts 92 pass through both ends of the grain box 1 and are rotatably connected to the bearing brackets 91 on both sides. The hydraulic motor 8 can provide power for the two feeding shafts 92. The feeding shaft 92 is connected to a spiral blade 93. The spiral blade 93 is tangent to the bottom wall and the inclined side wall of the inner box 18. The upper parts of the two spiral blades 93 are both fastened with angle plates 94. The two ends of the angle plates 94 are connected to the inner wall of the inner box 18. There is a gap between the two sides of the angle plates 94 and the side walls of the inner box 18. The middle part of the conveying end of the two angle plates 94 is connected to the loading cover 95, and the loading cover 95 is connected to the feeding mechanism 10.

[0040] The angle plate 94 guides the grain in the grain box 1 into the spiral blade 93 through the gap between the angle plate 94 and the inner wall of the inner box 18. The hydraulic motor 8 drives the feeding shafts 92 on both sides to operate synchronously in the same direction. The feeding shafts 92 drive the spiral blades 93 to rotate. The spiral blades 93 transport the grain that falls on the bottom of the inner box 18 to the upper material cover 95, and the grain enters the conveying mechanism 10 from the upper material cover 95. Since the angle plate 94 limits the feeding speed of the grain, it can effectively prevent the grain from being squeezed and damaged by a large amount of feeding.

[0041] The shaft ends of the hydraulic motor 8 are connected to the feeding shafts 92 on both sides through two sets of chain transmission 96;

[0042] The hydraulic motor drives the feeding shafts 92 on both sides to run synchronously and in the same direction through two sets of chain transmissions 96, and the chain transmissions 96 are not easy to slip.

[0043] A gap is left at the bottom of the gap between the two corner plates 94 to provide a corner plate 97, and the two ends of the corner plate 97 are respectively connected to the inner wall of the inner box 18 and the outer surface of the material cover 95;

[0044] The angle plate 2 97 blocks the gap in the middle of the two angle plates 1 94 and guides the grain in the middle to the spiral leaves on both sides, so that the grain will not be stored in the dead corner in the middle.

[0045] The feeding mechanism 10 includes an adjustable gearbox 101, which is connected to the power bracket 2. The power of the input shaft 3 is transmitted to the feeding shaft 102 through the adjustable gearbox 101. The feeding shaft 102 is rotatably connected to the bottom wall of the inner box 18. The feeding shaft 102 passes through the upper cover 95. The feeding spiral blade 103 is connected to the outside of the feeding shaft 102. The feeding spiral blade 103 is located in the feeding barrel 104. The feeding barrel 104 is connected to the upper cover 95. The upper end of the feeding barrel 104 is rotatably connected to an elbow 105.

[0046] The power of the input shaft 3 is transmitted to the feed shaft 102 through the adjustable gearbox 101. The transmission ratio of the adjustable gearbox 101 is adjusted according to the feeding speed to adapt to grains of different particle sizes and humidity. The feed shaft 102 drives the feed spiral blade 103 to rotate. The feed spiral blade 103 cooperates with the feed barrel 104 to transport the grain into the elbow 105. The angle of the elbow 105 is adjusted to adjust the discharge position.

[0047] Embodiment 2:

[0048] The following is combined with Figure 5 On the basis of the first embodiment, a grain transport vehicle with hydraulic control and regulation is described in this embodiment. The oil inlet end of the hydraulic pump 4 is connected to the bottom of the oil tank 6 through the oil pipe 1 11, and the oil outlet end of the hydraulic pump 4 is connected to the oil inlet end of the hydraulic regulating valve 7 through the oil pipe 2 12. The two oil outlet ends of the hydraulic regulating valve 7 are respectively connected with the oil pipe 3 13 and the oil pipe 4 4. The oil pipe 3 13 is connected to the oil inlet end of the hydraulic motor 8, and the oil pipe 4 4 ​​is connected to the upper part of the oil tank 6. There are two hydraulic motors 8. The oil outlet ends of the two hydraulic motors 8 are connected to the oil inlet ends through the oil pipe 6 19, and the oil outlet end of the other hydraulic motor 8 is connected to the upper part of the oil tank 6 through the oil pipe 7 20. The shaft ends of the two hydraulic motors 8 are respectively connected to the feeding shafts 92 on both sides;

[0049] Using two hydraulic motors 8 instead of chain drive 96 greatly reduces the transmission failure rate.
