Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to an angle-adjustable gantry frame for agricultural machinery. Background Art

[0002] In the mid- to late-stage management of sugarcane, to achieve high yields, defoliation, pesticide application, and fertilization are key priorities during this period. Due to rising labor and planting costs, many growers plant sugarcane at higher densities, with row spacings ranging from 70-100 cm, to increase yield per unit area. This results in the inability to use some large agricultural machinery. Furthermore, some planting sites are uneven, with slopes exceeding 10°, rendering existing agricultural machinery unusable. This is due to the irrational design of existing agricultural machinery. For example, components such as the medicine storage tank, engine, and cab are all mounted on the upper portion of the frame, which shifts the center of gravity upward. Consequently, existing agricultural machinery chassis generally do not exceed 2 meters, yet the height of sugarcane in the mid- to late-stage stages exceeds 2 meters, limiting the use of existing agricultural machinery.

[0003] Therefore, the utility model proposes an adjustable angle gantry frame for agricultural machinery with a simple structure and easy promotion. The center of gravity of the agricultural machinery matched with it is low, and it can work normally on slopes greater than 10°, and can operate in sugarcane fields with a height of 2-3.5 meters and a row spacing of 70-100 cm. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable angle gantry frame for agricultural machinery, thereby overcoming the defect that existing agricultural machinery cannot be used on densely planted land with a slope angle greater than 10°. The specific technical solution is as follows:

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] refer to Figure 1 and Figure 2 An adjustable angle gantry frame for agricultural machinery includes a left frame 1, a right frame 2 and an upper frame 5. The left frame 1 is composed of two first keels 3 and a plurality of first pipes 4 that are fixedly connected to form a frame. The right frame is composed of two second keels 6 and a plurality of second pipes 7 that are fixedly connected to form a frame. In order to enable the adjustable angle gantry frame for agricultural machinery to work normally on a slope greater than 10°, the upper frame 5 is rotatably connected to form a frame by two upper and lower third keels 14 and a plurality of third pipes 15, and the third pipes 15 are located between the third keels 14. The tops of the left frame 1 and the right frame 2 are connected to the two ends of the upper frame 5 by hinges to form an adjustable angle gantry frame for agricultural machinery.

[0025] A push rod 9 is provided on the left and right frames 1 and 2. One end of the push rod 9 is connected to the side wall of the left frame 1 near the upper frame 5 via a hinge, and the other end is pivotally connected to the upper frame 5 via a hinge. The right frame 2 has the same structure. The angle of the adjustable angle gantry frame for agricultural machinery is adjusted by telescoping the push rod 9 to adapt to operations on sugarcane fields with different slopes. To ensure the safety of the adjustable angle gantry frame for agricultural machinery, multiple limiters 10 are installed at the locations where the left and right frames 1 and 2 pivotally connect to the upper frame 5. When the upper frame 5 rotates excessively with the left or right frame 1 or 2, the limiters 10 abut against the upper frame 5, limiting the adjustable angle gantry frame for agricultural machinery to within a set angle range. This also prevents the adjustable angle gantry frame from tipping over if the push rod 9 fails. The limiters 10 can be limit blocks, limit switches, limit slots, etc. The number of limiters 10 can be determined based on actual conditions. The travel wheels 8 are rotatably mounted on the bottom of the adjustable angle gantry frame for agricultural machinery. The push rods 9 include electric push rods and hydraulic push rods. The push rods 9 can be used individually or in symmetrical pairs, and the selection can be based on the specific size of the adjustable angle gantry frame for agricultural machinery.

[0026] The width of the adjustable-angle gantry frame for agricultural machinery is the width of two to three sugarcane rows, meaning the distance between the left and right frames 1 and 2 is approximately 1.2 to 2.6 meters. To ensure the gantry frame and its associated agricultural implements can properly access sugarcane fields during the middle and late stages of sugarcane harvesting, when sugarcane heights are typically 2 to 3.5 meters, the height of the gantry frame is set to 2 to 3.5 meters, meaning the distance between the bottom of the upper frame 5 and the ground is 2 to 3.5 meters. To lower the center of gravity of the gantry frame, the distance between the first keels 3 and the second keels 6 is set to 40 to 70 centimeters, and the distance between the second keels 6 is set to 40 to 70 centimeters. Components such as the engine, cab 11, and medicine storage tank are mounted within the left and right frames 1 and 2. In order to make the angle-adjustable gantry frame for agricultural machinery work properly and stably, counterweight brackets 13 are installed at the front ends of the left frame 1 and the right frame 2 in the forward direction, and different counterweight blocks are configured according to different working conditions.

[0027] The adjustable-angle gantry frame for agricultural machinery can be equipped with a sugarcane defoliator to transform it into a sugarcane defoliator; with a high-pressure spray system, it can become a sugarcane pesticide sprayer; and with a fertilizer applicator, it can become a fertilizer spreader. Therefore, the adjustable-angle gantry frame for agricultural machinery can be equipped with a variety of devices to achieve multiple functions. Similarly, the present invention can also be used in other orchards with higher planting densities, thus demonstrating its high practicality.

[0028] Next, the working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0029] When the agricultural machinery with an adjustable angle gantry frame and corresponding agricultural implements works in a relatively flat sugarcane field, the left frame 1 and the right frame 2 are in a vertical position relative to the ground, the upper frame 5 is in a horizontal position, and the push rod 9 on the vehicle does not work.

[0030] refer to Figure 3 When the adjustable-angle gantry frame for agricultural machinery, equipped with corresponding agricultural implements, is used in a sugarcane field with a certain slope, push rod 9 is activated to adjust the angle between the left and right frames 1 and 2 and the upper frame 5. After the adjustment, the left and right frames 1 and 2 are in a vertical position, with the right frame 2 higher than the left frame 1 and the upper frame 5 parallel to the slope. This ensures that the adjustable-angle gantry frame for agricultural machinery can operate normally on sloped ground, improving the efficiency of the adjustable-angle gantry frame for agricultural machinery.

[0031] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of illustration and description. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials or characteristics described can be combined in an appropriate manner in any one or more embodiments or examples. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can make modifications, substitutions, variations and various different choices and changes to the embodiments without creative contribution as needed after reading this specification without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
