DETAILED DESCRIPTION
[0016] The technical content of the utility model is described in detail below with reference to the accompanying drawings.
[0017] like Figure 2 As shown, the self-propelled full-day ration spreader includes a frame 15, on which are mounted an engine, a tandem pump group 3, a front wheel assembly 20, a right rear wheel assembly 27, a left rear wheel assembly, a battery pack 18, a reversing pedal 19, a reversing pull rod 16, a seat 17, a control console 21, a steering assembly 22, a weighing display 23, an augers 25, a hopper assembly 24 and a weighing sensor 26.
[0018] The series pump group (3) is driven by the engine to provide working power to the auger motor (5), the material gate cylinder (8), the hydraulic power steering device (9) and the three travel motors. The travel speed of the whole machine, the speed of the auger 25 and the weighing sensor 26 cooperate to achieve quantitative feeding. The series pump group (3) is supplied with oil by the oil tank 1, and an oil suction filter 2 is provided at the outlet of the oil tank 1.
[0019] The front wheel assembly 20 is equipped with a front wheel motor 14, the right rear wheel assembly 27 is equipped with a right rear wheel motor 12.1, and the left rear wheel assembly ( Figure 2 The left rear wheel motor 12.2 is installed. The three motors are powered by a variable gear pump 3.1. The electromagnetic reversing valve 13 is operated to quickly switch the series and parallel connection of the hydraulic motors to achieve the change of the transfer speed and the operating speed. The electromagnetic reversing valve 13 is in position A ( Figure 1 When the electromagnetic reversing valve 13 is in position B, the left rear wheel motor 12.1, the rear wheel motor 12.2 and the front wheel motor 14 are connected in parallel, and then connected in series with the front wheel motor 14. At this time, the front and rear wheel speeds are at a high speed position, which is used for the transfer operation; when the electromagnetic reversing valve 13 is in position B, the left rear wheel motor 12.1, the rear wheel motor 12.2 and the front wheel motor 14 are connected in parallel, and at this time, the front and rear wheel speeds are at a low speed position, which is used for the material spreading operation. The hydraulic control of the front wheel motor 14, the right rear wheel motor 12.1 and the left rear wheel motor 12.2 is a common technology in the field and will not be described here.
[0020] When the auger electromagnetic control valve 4 is in the middle position, the 12cc quantitative gear pump A3.2 hydraulic oil flows directly back to the oil cylinder through the oil circuit, and the auger motor 5 does not work at this time; Figure 1 When the hydraulic oil flows out of the quantitative gear pump A3.2 in the upper position, it enters the auger motor 5 through the pressure stabilizing valve. The auger motor 5 rotates, and a one-way back pressure valve 11 is set in the oil return line to make the auger motor 5 rotate at a constant speed, thereby realizing quantitative operation; the auger electromagnetic control valve 4 is in Figure 1 When in the lower position as shown, the hydraulic oil flowing out of the quantitative gear pump A3.2 enters the auger motor 5 through the one-way valve, and the auger motor 5 rotates in the reverse direction, which is suitable for use when materials are blocked during operation.
[0021] The 6cc quantitative gear pump B3.3 is connected to the material gate cylinder 8 and the hydraulic power steering gear 9 to provide power.
[0022] For ease of operation, a one-way flow stabilizing valve 6, a material gate oil cylinder electromagnetic control valve 7, a material gate oil cylinder 8, a hydraulic power steering gear 9, an oil return filter 10, and a one-way valve 11 are provided. To ensure the working stability of this part of the hydraulic system, a one-way flow stabilizing valve 6 is designed on the oil inlet line to keep the working pressure within a safe and reliable range, while reducing damage to the hydraulic actuators and increasing their service life; to ensure that the hydraulic oil in the lifting cylinder is kept at a certain pressure, a one-way valve 11 is designed in the oil return line of the oil cylinder. At this time, the one-way valve 11 acts as a hydraulic lock, so that the hydraulic cylinder is in the lifting state and the hopper door is open for unloading. Since the hydraulic steering booster 9 is frequently used, an oil return filter 10 is designed on the oil return line.
