Description

Technical Field

[0001] This utility model relates to the field of loader technology, and in particular to a loader. Background Technology

[0002] Loaders are widely used in sand and gravel plants, concrete mixing plants, railways, highways, mines, metallurgy, and other fields. They are mainly used for shoveling, loading, unloading, and transporting bulk materials, and can also perform light excavation work on native soil. Due to their advantages such as high operating speed, high efficiency, good maneuverability, and ease of operation, loaders have become a major type of earthmoving machinery in the construction machinery field. Because of their long working hours and complex working conditions, the wear and tear on various components of the machine is also relatively high. To ensure the normal operation of the loader, regular maintenance is required at short intervals. Whether the overall design layout of the machine maximizes the convenience of use and maintenance is an important factor in evaluating the quality of a loader.

[0003] For the current overall layout structure of domestic loaders, please refer to [reference needed]. Figure 8 and Figure 9 The driver faces numerous inconveniences during daily use and maintenance. The main components are: 1. Most of the existing urea tanks (60) are located near the counterweight at the rear of the machine, and some are located inside one side of the counterweight. The existing urea filling port (50) is located on the side of the counterweight. 2. Most of the existing battery boxes (40) are also located inside the other side of the counterweight, symmetrically arranged with the existing urea tanks (60). Before each operation, the driver needs to turn on the negative power switch. When turning on the negative battery switch, the driver needs to walk to the rear of the vehicle, turn on the negative switch, and then walk to the existing cab ladder (30) near the hinge center of the vehicle to enter the cab. The round trip distance is the same as that of the existing urea tank (60), which is far from the location where the driver goes up and down the existing cab ladder (30). 3. The existing fuel tank (70) is generally located on one side of the left and right ladders of the cab, symmetrically arranged with the existing hydraulic oil tank (20). The existing fuel tank (70) is made of iron. 4. When maintaining internal components such as the engine assembly under the hood, most manufacturers' hoods are tilted forward at an angle. (See reference...) Figure 9 Alternatively, the existing side windows (80) on both sides of the hood can be opened at a certain angle, and most of the time the hood is opened by manually pushing the gas spring push rod, which is quite laborious.

[0004] The existing loader layout has the following shortcomings: 1. The urea tank is located near the rear counterweight or inside one side of the counterweight, with the filling port on the side of the counterweight. The disadvantages are: a) When filling, the approximately 30kg urea tank needs to be manually lifted, taking about 2-3 minutes to fill 30 liters, resulting in high workload; b) During operation, dust accumulates near the rear counterweight compared to the front, easily contaminating the urea tank's interior and affecting the engine's aftertreatment reliability; c) The urea tank is too far from the driver's cab, increasing the driver's daily workload. 1. When the dashboard in the cab shows insufficient urea and an alarm sounds, the driver drives the vehicle to a convenient place to add urea, turns off the engine, gets out of the cab, carries the urea tank to the rear of the vehicle to add urea, and then returns to the cab via the ladder near the articulation center to start working again. The round trip distance is relatively long. 2. The disadvantage of placing the battery box on one side of the counterweight: Before each operation, the driver needs to walk to the rear of the vehicle to turn on the power, and then go to the cab via the ladder near the articulation center to enter the cab. The round trip distance is the same as when adding urea, which is much longer than the distance the driver needs to go up and down the ladder. 3. Shortcomings of the fuel tank location on one side of the left and right ladders of the cab: a) The hydraulic oil tank and fuel tank are similar in size and shape, often resulting in fuel being mistakenly added to the hydraulic oil tank; b) The fuel tank is made of iron, and the diesel fuel often contains a small amount of water. Over time, the inside of the fuel tank is prone to rust, which affects the cleanliness of the fuel and the reliability of the engine; 4. Shortcomings of the existing engine hood opening method: When maintaining the engine assembly, the engine hood is flipped forward at an angle or the side windows on both sides of the engine hood are opened upward or forward at a certain angle. The shortcoming of these two opening methods is that the various components of the engine assembly are not fully exposed, resulting in insufficient maintenance space and causing many inconveniences for maintenance.

When the driver is about to use the loader or not, they can directly turn the negative power switch on or off near the ladder leading to the cab, without having to walk to the counterweight at the rear of the machine. This is very convenient. Urea can also be added directly from the ladder leading to and from the cab. For ease of urea addition, the battery and urea tank are arranged in an ergonomic manner: the urea tank is at the bottom, separated by a partition, and the battery is above it. This arrangement eliminates the need to bend over when turning the negative power switch on or off, and avoids lifting the urea tank to a high position when adding it. Therefore, this invention provides a completely new loader layout that facilitates daily maintenance and repair for the user (see...). Figure 1 It is designed with the driver in mind, aiming to maximize the convenience and user experience for drivers. Attached Figure Description

[0032] See Figures 1 to 7 This embodiment provides a loader, including a loader body 1, a bucket 2 at the front end of the loader body 1, a cab 3 in the middle of the loader body 1, a counterweight 4 at the rear end of the loader body 1, a front wheel 5 at the lower front of the loader body 1, a cab ladder 6 at the lower left or right of the cab 3, and a rear wheel 7 at the lower rear of the loader body 1; a battery box 8 and a urea tank 9 are located below the cab 3, with the battery box 8 above the urea tank 9 and the battery box 8 and urea tank 9 located close to the inner side of the cab ladder 6; a battery 801 is located inside the battery box 8, and a urea tank 901 is located inside the urea tank 9, separated by a partition; a negative power switch 802 is located on the battery 801, and a urea filling port 902 is located on the urea tank 901. Functions: 1. The loader body has a bucket at the front end, a cab in the middle, a counterweight at the rear, a front wheel at the lower front, a cab ladder at the lower left or right, and a rear wheel at the lower rear; thus providing the basic functions of the loader (such as driving and other traditional basic functions). 2. The cab has a battery box and a urea tank at the bottom, the battery box is above the urea tank, and the battery box and urea tank are close to the inside of the cab ladder; the battery box contains a battery, the urea tank contains a urea tank, the battery and urea tank are separated by a partition, the battery has a negative power switch, and the urea tank has a urea filling port; thus achieving the overall layout as follows: (1) The battery and urea tank, which are used most frequently by the driver, are placed below the ladder for the driver to go up and down the cab (see Figure 2(A partially enlarged view showing the arrangement of the battery and urea tank in the housing is omitted). When the driver is about to use the loader or not, they can directly turn the negative power switch on or off near the ladder leading to the cab, without having to walk to the counterweight at the rear of the machine. This is very convenient. Urea can also be added directly from the ladder leading to and from the cab. For ease of urea addition, the battery and urea tank are arranged in an ergonomic manner: the urea tank is at the bottom, separated by a partition, and the battery is above it. This arrangement eliminates the need to bend over when turning the negative power switch on or off, and avoids lifting the urea tank to a high position when adding it. Therefore, this invention provides a completely new loader layout that facilitates daily maintenance and repair for the user (see...). Figure 1 It is designed with the driver in mind, aiming to maximize the convenience and user experience for drivers.

[0033] Specifically, the rear end of the loader body 1 also includes a fuel tank 10 and an engine 11. The fuel tank 10 is located behind the engine 11, between it and the counterweight 4. Its function is to position the fuel tank behind the engine, between it and the counterweight (see...). Figure 3 This is to avoid the frequent occurrence of accidentally adding fuel to the hydraulic oil tank when adding fuel, as the hydraulic oil tank and fuel tank are similar in size and shape.

[0034] Specifically, the fuel tank 10 is a plastic fuel tank, and a protective plate 12 is provided on the bottom and around the fuel tank 10. Function: The plastic material solves the problem of rust formation inside iron fuel tanks; the protective plate 12 on the bottom and around the plastic fuel tank solves the problem of poor impact resistance of plastic fuel tanks.

[0035] Specifically, the protective plate 12 is an iron cover, and the fuel tank 10 is less than 3mm thick. Function: Because the iron cover provides protection and is less than 3mm thick, the problem of poor impact resistance of the plastic fuel tank is solved by adding the iron cover.

[0036] Specifically, a hood 13 is provided on the upper rear of the loader body 1, which covers the fuel tank 10 and the engine 11. Function: The hood 13 protects the fuel tank 10 and the engine 11.

[0038] Specifically, a breather 1002 is connected to the fuel tank 10, and the breather 1002 is provided with a breather hole 1003. The breather hole 1003 can prevent negative pressure from forming due to insufficient air entering the inner cavity of the plastic fuel tank as fuel decreases, which would cause the plastic fuel tank to collapse and deform. Function: By providing a breather hole for the fuel tank (see...) Figure 5 This is to prevent the plastic fuel tank from collapsing and deforming due to insufficient air intake as fuel decreases inside.

[0039] Specifically, the hood 13 is connected to the loader body 1 via an electric cylinder 14, and the hood 13 can be pushed open by the electric cylinder 14 to tilt backward. Function: The hood opens using an integral tilting structure (see...). Figure 6 The rear hood opens at a large angle, exposing components such as the engine, which facilitates maintenance and upkeep. The hood is opened by an electric cylinder, which is convenient and labor-saving.

[0040] Specifically, the battery 801 is equipped with a cover opening button 15, which is electrically connected to the electric cylinder 14. Function: See the enlarged view of the cover opening button 15 and the power negative switch 802. Figure 7 Press the "Open Cover" button 15, and the electric cylinder 14 will open the cover.

[0041] Specifically, the loader body 1 includes a loader frame 101 and a hydraulic oil tank 102. Function: The loader frame 101 provides the mounting positions for various components. The hydraulic oil tank 102 can also be located below the cab. Since these are conventional technologies, the selection can be made according to actual needs, and will not be elaborated further here.

[0042] This utility model can be applied to loaders that meet the National IV emission standards and above.

[0043] The differences between this technical solution and existing technologies are as follows:

[0044] Compared with existing technologies, this technical solution solves the problem of convenience for drivers in daily use, maintenance, and repair.
