Description

Technical area

[0001] The utility model relates to the field of mechanical devices and in particular to a mechanical device. Background technology

[0002] In agricultural production, from tillage to soil preparation before sowing, digging is the fundamental and crucial link. Traditional manual tillage equipment, such as hoes, is entirely driven by human power, which is extremely inefficient and difficult to meet the needs of large areas of land. Existing small earthmoving machinery either has a single function and cannot cope with complex terrain and diverse soil conditions, or is cumbersome to operate, requiring high operator skill. Therefore, it is urgently necessary to develop a mechanical device with a sophisticated structure, convenient operation, and power adjustment that can adapt to a variety of working conditions. Content of the utility model

[0003] The purpose of the utility model is to overcome the above-mentioned problems and provide a mechanical device. To achieve the above-mentioned purpose, the utility model uses the following technical solutions: A mechanical device consisting of a handle component, a hydraulic rod, an earth digging component, and an extension mechanism. The handle component is provided with a hydraulic rod inside. One end of the handle component is connected to the earth digging component via a connecting piece. The extension mechanism is installed outside the earth digging component. The handle component includes a handle rod and a hydraulic rod connecting seat. The handle rod is welded to one end of the hydraulic rod connecting seat.

[0004] As an important part of the direct interaction between the operator and the mechanical device, the handlebar has a special anti-slip treatment on the surface, ensuring the stability of the operator when holding and not easy to slip even in wet or dirty environments, so that the operator can effectively reduce the fatigue caused by long-term operation in operations such as pushing, rotating, lifting, etc. At the same time, this design helps the operator to precisely control the direction and strength of the device, whether it is large-scale earth excavation work on flat land or delicate operations in a small space, it can ensure the stability and accuracy of the operation process.

[0005] The hydraulic rod connecting seat and one end of the handle bar are firmly connected by welding, forming a stable whole. Its main function is to provide a reliable installation position for the hydraulic rod and ensure that the hydraulic rod does not shake or move within the handle assembly. The structural design of the hydraulic rod connecting seat has been optimized and is made of high-strength material that can withstand the strong pressure and impact force generated by the hydraulic rod during operation. During operation, the piston inside the hydraulic rod moves under the pressure of the hydraulic oil to generate power, and the hydraulic rod connecting seat precisely transmits this power to the handle bar, allowing the operator to easily overcome the resistance of the ground with hydraulic power and successfully complete the earthmoving operation.This force effect is particularly pronounced on hard floors.

[0006] In addition, the excavation component consists of an outer casing, an auger rod, and a drill bit. The auger rod and drill bit are mounted inside the outer casing. The drill bit is attached to the upper end of the auger rod.

[0007] In the earth excavation component, the outer shell is the main supporting structure of the earthmoving component. It is made of high-strength metal material and exhibits good compressive strength, wear resistance, and corrosion resistance. The main function of the outer shell is to provide reliable protection and a stable installation base for the internal auger rod and drill bit. During earthmoving work, the drill rod rotates at high speed, generating enormous torque. Furthermore, the ground exerts a strong reaction force on the rod. The outer shell can effectively withstand these forces, thus ensuring the stability of the entire earth excavation component during the work process.In addition, the sealed design of the outer shell can prevent soil, sand and debris from entering the interior, thereby avoiding malfunctions and damage to the operation of the auger rod and drill and extending the service life of the components.

[0008] The auger bar is the central executive component in earthmoving operations. It consists of a high-strength metal bar body and spiral blades wound around its surface. The pitch, diameter, and shape of the spiral blades are carefully designed and optimized to meet the characteristics and excavation requirements of different soil types. In soft sand, spiral blades with a larger pitch can transport the soil quickly. In stickier soils, spiral blades with a smaller pitch and a special shape are used for better cutting and transporting the soil. During operation, the auger bar rotates at high speed, uses the cutting edge of the spiral blade to cut the soil and lift it upward along the spiral path of the spiral blade, thereby achieving efficient earth excavation and conveyance. It is a key component for ensuring the smooth progress of earthmoving operations.

[0009] The auger bit is attached to the top of the auger rod and forms the spearhead of the entire device, cutting into the ground. It is made of a super-hard alloy material with extremely high hardness and wear resistance. The auger bit features a sharp cone shape, which can concentrate the force on a single point when the device begins to dig the ground, thus easily breaking up the ground surface. When drilling into the ground, the auger bit's hard material and sharp tip overcome the soil resistance, thus creating the conditions for the twist drill rod to dig deeper. At the same time, the surface of the auger bit has been specially treated to ensure good wear resistance and corrosion resistance, allowing it to operate stably for a long time in harsh ground environments, thus ensuring the efficiency of earth excavation and the operation quality of the device.

[0010] In addition, the expansion mechanism includes a plurality of connecting rods and a support rod. The upper end of the connecting rod is attached to the lower end of the outer shell, and the middle section is welded to one end of the support rod. The other end of the support rod is slidably connected to the outer shell.

[0011] One end of the support rod is firmly connected to the center of the connecting rod by welding, and the other end is connected to the outer shell by sliding. This connection method allows the support rod to slide smoothly along the surface of the outer shell and unfold after the earth excavation component penetrates the ground. When the support rod is extended, it can effectively expand the contact area between the device and the ground. Since the expansion mechanism consists of four groups and is evenly installed circumferentially on the outer shell, the device can be evenly stressed during soil excavation, thus avoiding deviations or insufficient local excavation.At the same time, the extended support rods can move more soil, which greatly improves the efficiency of excavation, improves the performance of the entire mechanical device in large-scale excavation work, and ensures the consistency and efficiency of the excavation effect.

[0012] The advantages of the utility model are: The utility model enables efficient earth excavation through the coordinated operation of the handle component, the hydraulic rod, the earth digging component, and the extension mechanism. The handle component reduces operator labor intensity and improves work accuracy. In the earth digging component, the outer shell protects the internal structure and provides stable support. The auger rod and auger are optimized for different soils to ensure efficient excavation. The extension mechanism can expand the earth excavation area and improve efficiency. Its structural design is rational and ensures overall stability, making it suitable for a wide range of earth excavation scenarios.
