[0017] (III) Beneficial Effects

[0018] This utility model provides a mechanical device for laying straw checkerboard patterns in the desert, which has the following beneficial effects:

[0019] The tracked wheels used in the walking mechanism can avoid the slippage and sinking that are common when using wheeled mechanical devices in the desert. At the same time, the hydraulic shock absorber can reduce the vibration and bumps that occur when the hay tying machine is tying hay.

[0020] The lower arc-shaped axe-like weed tier of the weed-tying mechanism in this device rises and falls through the rotation of the upper blades, thereby using inertia to compact the conveyed material. Due to inertia, the weed tier can maintain its motion to a certain extent, reducing reliance on the electric motor, thus lowering energy consumption and improving the working efficiency of the weed tier. The symmetrical distribution of the first and second weed ties not only ensures deep integration with the material storage and feeding mechanism but also maintains the overall balance of the device.

[0021] In the compaction mechanism of this device, every two compaction wheels and the compaction wheel connecting rod form a combination. This combination can gather the sand and soil around the trench and play a compaction role after the straw tying machine tamps the material conveyed out. The use of round compaction wheels can convert friction into rolling friction, which can reduce the resistance of the overall device's movement.

[0022] The feeding rollers in the storage and feeding mechanism of this device are made of smooth, conical, lightweight steel with spikes around their perimeter. This design avoids the material entanglement and blockage problem that easily occurs when using traditional material bins for feeding. Furthermore, the feeding rollers are distributed in a trapezoidal pattern using height differences, which not only improves the feeding efficiency of the material bin but also allows for control of the discharge volume at the feeding port by adjusting the rotation speed.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] A mechanical device for laying straw checkerboard patterns in the desert, such as Figures 1 to 6As shown, the vehicle includes a chassis 11, a connecting rod 108, a first spring connector 103, a second spring connector 106, a third spring connector 102, a fourth spring connector 104, a first hook rod 107, a second hook rod 105, a compaction mechanism 4 consisting of a first compaction wheel and a second compaction wheel, a first storage bin 202, a second storage bin 207, a first feeding roller 204, a second feeding roller 203, a third feeding roller 201, and a fourth feeding roller. The material storage and feeding mechanism 2, consisting of the fifth feeding roller 208, the sixth feeding roller 206, and the sixth feeding roller 205; the straw-tying mechanism 5, consisting of the first straw-tying machine and the second straw-tying machine; and the walking mechanism 3, consisting of the first track 302, the second track 303, the third track 305, the fourth track 311, the first track wheel bracket 304, the second track wheel bracket 307, the first shock-absorbing spring 310, the second shock-absorbing spring 309, the third shock-absorbing spring 308, the fourth shock-absorbing spring 306, and the hydraulic shock-absorbing rod 301. The material storage and feeding mechanism 2 conveys straw to the straw-tying mechanism 5 via the trapezoidal rollers. The straw-tying machine uses the rotating blades 501 and 502 to drive the arc-shaped axe-type straw-tying tool 513 to pierce the sand. The compaction mechanism 4 then compacts the sand. The tracks 302, 303, 305, and 311 of the traveling mechanism 3 work together with the shock-absorbing springs 306, 308, 309, and 310 and the hydraulic shock-absorbing rod 301 to ensure stable movement of the device.

[0032] like Figures 1 to 6 As shown, the hay-tying mechanism 5 includes a first hay-tying machine and a second hay-tying machine symmetrically distributed on the lower rear side of the frame mechanism 1. Each hay-tying machine includes a blade, a flywheel, a drive shaft, a pulley, a bracket, and an arc-shaped axe-type hay-tying tool. The blade is connected to the flywheel via the drive shaft, the flywheel drives the pulley via a belt, and the arc-shaped axe-type hay-tying tool is linked to the bracket via a connecting rod, utilizing the rotational inertia of the blade to complete the hay-tying action. Because the structure, appearance, and function of the first and second hay-tying machines are exactly the same, only the structure of the first hay-tying machine is shown in the attached diagram to avoid repetition in the images.

[0033] like Figures 1 to 6 As shown, the walking mechanism 3 includes a first track 302 and a second track 303 symmetrically arranged at the front, a third track 305 and a fourth track 311 symmetrically arranged at the rear, as well as a bracket and a shock absorption system connecting the track wheels; the shock absorption system includes four shock-absorbing springs 306, 308, 309, and 310 and a hydraulic shock-absorbing rod 301 mounted on the track wheel bracket.

[0034] like Figures 1 to 6As shown, the compaction mechanism 4 includes a first compaction wheel and a second compaction wheel symmetrically arranged on the lower rear side of the frame mechanism 1; each compaction wheel includes two compaction wheels and compaction wheel connecting rods 403 and 401. The compaction wheels gather and compact the sand through the wheel structure. Since the structure, shape, and function of the first compaction wheel and the second compaction wheel are completely identical, only the structure of the first compaction wheel is shown in the attached drawings to avoid repetition in the images.

[0035] like Figures 1 to 6 As shown, the first track 302, the second track 303, and the first track wheel bracket 304 play a steering role when the mechanical device turns. When the first and second hay bale machines are working, the first shock absorber spring 310, the second shock absorber spring 309, the third shock absorber spring 3, the fourth shock absorber spring 306, and the hydraulic shock absorber rod 301 mainly play a shock absorption role.

[0036] like Figures 1 to 6 As shown, since the first and second grass tying machines work in the same way, to avoid excessive redundancy, only the working method of the first grass tying machine will be described here. When the first grass tying machine is working, it mainly relies on the first blade 501 and the second blade 502 to rotate around the first drive shaft 503 to drive the first arc-shaped axe-type grass tie 513 to complete the grass tying action. When the grass tying machine has finished working, it can be hung on the first hook rod 107 to avoid damage when it is not working.
