Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a harvesting elevator. Background Technology

[0002] In modern agricultural production, with the continuous expansion of planting scale, crop harvesting has gradually become a labor-intensive process. This is especially true for harvesting tall crops such as fruit trees and tea trees, where traditional manual harvesting methods are often inefficient and labor-intensive. To address this issue, many agricultural machines have emerged, among which harvesting lifts, as a highly efficient tool, are widely used in orchards and other similar planting environments.

[0003] In existing technologies, harvesting lifts typically consist of main components such as a lifting platform, a drive system, a support structure, and a control system. Through their lifting mechanism, harvesting lifts allow operators to perform harvesting operations from a higher position, thereby improving harvesting efficiency and reducing the labor intensity of manual labor. However, although the use of harvesting lifts improves harvesting efficiency to some extent, existing harvesting lift technologies still have some significant drawbacks that limit their widespread application and promotion in actual agricultural production.

[0004] First, existing harvesting lifts generally suffer from significant weight. Due to the structural design aimed at ensuring stability, robust materials are often chosen, resulting in substantial equipment weight. This heaviness not only increases the difficulty of transporting and handling the equipment but also makes it difficult to move flexibly in confined and complex plantation environments. Particularly in areas with soft or uneven ground, the heavy equipment is even more difficult to move and park stably, increasing the workload for operators.

[0005] Secondly, existing harvesting lifts often lack fixed mechanisms, especially when in operation after being raised, as the center of gravity shifts with the platform's elevation. Because lifts are primarily designed for simplified operation, they lack effective support and stabilization systems. This makes the center of gravity higher after elevation, increasing susceptibility to external factors (such as wind and uneven ground) and increasing the risk of tipping over. Furthermore, existing harvesting lifts are difficult to move in plantation environments, often requiring additional mechanical assistance or multiple personnel for transport and relocation. Plantation grounds are typically uneven and contain numerous obstacles; existing equipment lacks sufficient mobility and cannot operate efficiently in confined spaces, increasing working time and costs. Utility Model Content

The vehicle body is fixedly equipped with a retractable folding frame, and the other end of the folding frame is equipped with an operating platform for supporting harvesting workers. The feature is that a walking ground stake unit is installed on the underside of the vehicle body, and the walking ground stake unit can switch between the walking wheels and the fixed ground stake according to the settings.

[0007] Preferably, the walking ground stake unit includes a shaft seat, a bushing, a bearing seat, a boss, and a insertion hole. The four corners of the bottom of the vehicle body are provided with shaft seats. Each shaft seat is slidably mounted with a bushing perpendicular to the direction of travel. One end of the bushing is provided with a limiting member for sliding limit of the shaft seat. The other end of the bushing is provided with a bearing seat. An independent half shaft is sleeved on the bushing. A wheel is mounted on the half shaft. A limiting bearing that fits with the bearing seat is mounted on the half shaft. The bearing seat is provided with a boss in the circumference. The boss is provided with a vertically downward insertion hole.

[0008] Preferably, the half-shaft has a guide portion at the end away from the wheel, and the bushing has an clearance groove adapted to the shape of the guide portion; the half-shaft has an optical axis area at the end away from the wheel, and the bushing has an optical axis groove adapted to the shape of the guide portion.

[0009] Preferably, the optical axis region of the half-shaft is provided with a self-tapping thread protruding from the circumferential surface of the optical axis region between the optical axis region and the limiting bearing.

[0010] Preferably, the bottom of the vehicle body is provided with a positioning sleeve that fits into the plurality of limiting members.

[0011] Preferably, the positioning sleeve has a guide taper on the side facing the wheel.

[0012] Preferably, the wheel has a plurality of grip slits in the circumferential direction to increase grip friction.

[0013] Compared with the prior art, the present invention provides a harvesting lift, which has the following beneficial effects:

[0014] 1. By installing axle seats at the four corners of the vehicle body and sliding axle sleeves within the axle seats, the stability and precision of the wheels are ensured. Simultaneously, the combined design of the axle sleeves, limiting components, and bearing seats increases the device's shock resistance and anti-slip properties, preventing instability during operation and improving the device's reliability and safety.

[0015] 2. When fixed in place, pull out the bushing, remove the half shaft from the bushing, insert the guide part of the half shaft into the ground, rotate the wheel to increase the length of the power arm, and use the self-tapping threads on the half shaft to insert the half shaft deeply into the ground, forming a ground nail fixed to the ground, thus improving safety.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] The following is combined Figures 1 to 3 This application introduces a harvesting lift, including a vehicle body 1, a folding frame 2, and an operating platform 3. The folding frame 2 with a retractable length is fixedly installed on the vehicle body 1, and the operating platform 3 for carrying the harvesting operator is installed at the other end of the folding frame 2. A walking ground spike unit is installed on the lower side of the vehicle body 1, and the walking ground spike unit can switch between the walking wheel and the fixed ground spike according to the setting.

[0023] The walking ground stake unit includes axle seat 4, bushing 5, bearing seat 6, boss 7, and insertion hole 8. Axle seat 4 is provided at each of the four corners of the bottom of the vehicle body 1. A bushing 5 perpendicular to the direction of travel is slidably installed on each axle seat 4. One end of the bushing 5 is provided with a limiting member 9 for sliding limit of the axle seat 4. The other end of the bushing 5 is provided with a bearing seat 6. An independent half shaft 10 is sleeved on the bushing 5. A wheel 16 is installed on the half shaft. A limiting bearing 12 that fits with the bearing seat 6 is installed on the half shaft. The bearing seat 6 is provided with a boss 7 around its circumference. The boss 7 is provided with a vertically downward insertion hole 8.

[0024] The half-shaft has a guide portion 14 at the end away from the wheel 16, and the bushing 5 has a clearance groove that matches the shape of the guide portion 14; the half-shaft also has a light axis area 13 at the end away from the wheel 16, and the bushing 5 has a light axis groove that matches the shape of the guide portion 14. This increases the ease of fitting and improves user comfort.

[0025] The optical axis area 13 of the half-shaft is provided with a self-tapping thread 11 protruding from the circumferential surface of the optical axis area 13 between the half-shaft and the limiting bearing 12, which facilitates the insertion of the independent half-shaft 10 into the soil to form a positioning.

[0026] The bottom of the vehicle body 1 is provided with a positioning sleeve 15 that fits into the multiple limiting members 9, thereby reducing the force on the axle seat 4 and improving its stability.
