Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a no-till machine test bench. Background Technology

[0002] No-till machines, as key equipment for conservation tillage in agricultural production, directly impact crop emergence rate and growth quality through their seeding performance. Current technologies typically rely on actual field conditions for testing no-till machine seeding performance. This involves manually checking seed penetration depth, distribution uniformity, and coverage after the machine has driven through a field and completed seeding. While this method realistically reflects the machine's operation in natural soil environments, it also has significant limitations. Firstly, actual field testing is affected by soil conditions, climate, and seeding time, making repeatable testing under controlled conditions difficult. Secondly, actual testing requires large areas of farmland, is complex and costly, and is not convenient for frequent testing during the early stages of R&D or equipment debugging, thus affecting R&D efficiency and the speed of equipment improvement. Therefore, current technologies lack a testing device that can simulate the actual movement and seeding process of a no-till machine in a non-field environment, preventing researchers from conducting intuitive and convenient testing and observation of the seeding performance in a laboratory or workshop. Therefore, it is necessary to propose a no-till machine test bench to solve the above problems. Utility Model Content

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] Please see Figures 1 to 3 The no-till machine test bench provided by this utility model includes two sets of symmetrically arranged test bench modules 1 and a motor 5; the test bench module 1 includes a sand conveying component 2, a sand lifting component 3 disposed at the front end of the sand conveying component 2, and a no-till machine wheel conveying component 4 disposed on one side of the sand conveying component 2, and the motor 5 is disposed below the no-till machine wheel conveying component 4 of one of the test bench modules 1.

[0020] The motor 5 serves as the power source for the entire device, driving all transmission components to operate in coordination, ensuring the automation and stability of the testing process. The sand conveying assembly 2 includes an upper sand conveyor belt 21, upper sand conveyor belt rollers 22 positioned at both ends of the upper sand conveyor belt 21, a lower sand conveyor belt 23, lower sand conveyor belt rollers 24 positioned at both ends of the lower sand conveyor belt 23, and a seed screen 25. The upper sand conveyor belt 21 is parallel to and above the lower sand conveyor belt 23, simulating the surface soil environment for the no-till machine to perform seeding operations. The rear end of the upper sand conveyor belt 21 is shorter than the lower sand conveyor belt 23. The seed screen 25 is inclined and positioned at the rear end of the upper sand conveyor belt 21 and above the lower sand conveyor belt 23. The seed screen 25 can separate the seeds from the sand after sowing, facilitating seed recovery and observation of the sowing effect. Simultaneously, the lower sand conveyor belt 23 can catch falling sand, enabling sand recycling. An upper gear 26 is coaxially connected to the inner side of the upper sand conveyor roller 22, and a lower gear 27 that meshes with the upper gear 26 is coaxially connected to the inner side of the lower sand conveyor roller 24. Through gear meshing transmission, the synchronous movement of the upper sand conveyor belt 21 and the lower sand conveyor belt 23 can be ensured, and the accumulation or disengagement of sand during the transmission process can be avoided.

[0021] The sand lifting assembly 3 includes a sand recovery channel 31 located below the front end of the lower sand conveyor belt 23, a sand shovel drive assembly 32 located above the sand recovery channel 31, a sand shovel 33 that is circulated and raised on the sand shovel drive assembly 32, and a sand delivery channel 34 located behind the top of the sand shovel drive assembly 32 and extending above the upper sand conveyor belt 21. The sand recovery channel 31 can collect the sand conveyed by the lower sand conveyor belt 23. The sand shovel drive assembly 32 drives the sand shovel 33 to circulate and raise, lifting the sand from the sand recovery channel 31 to the sand delivery channel 34, and finally delivering it to the upper sand conveyor belt 21, forming a closed-loop sand circulation system and reducing sand loss during the testing process.

[0022] The no-till machine wheel transmission assembly 4 includes a wheel conveyor belt 41 and wheel conveyor belt rollers 42 set at both ends of the wheel conveyor belt 41. The wheel conveyor belt 41 is used to support the wheels of the no-till machine and simulate the road surface. A lower horizontal shaft 43 is set on one side of the motor 5. The lower horizontal shaft 43 is connected to the upper horizontal shaft 45, which is coaxially connected to the outside of the sand conveyor belt roller 22, through the transmission shaft 44. The output shaft of the motor 5 is sequentially connected to the wheel conveyor belt roller 42 and the lower horizontal shaft 43. Through the multi-axis linkage design, the speed matching between the wheel conveyor belt 41 and the sand conveyor belt 21 can be realized to simulate the sowing state of the no-till machine at different driving speeds. The upper gear 26 is connected to the sand-collecting shovel drive assembly 32. The upper gears 26 of the two sets of test bench modules 1 are coaxially connected to ensure the synchronous operation of the two test bench modules 1 and improve the symmetry and stability of the test.

[0023] An adjustment mechanism for adjusting the distance between the two sets of test platform modules 1 is provided between the front and rear ends of the test platform module 1, which can be adapted to no-till machines with different wheel gauges and enhance the versatility of the device; the output shaft of the motor 5 is connected to the wheel conveyor belt roller 42 and the lower horizontal shaft 43 in sequence through a sprocket mechanism, and the upper gear 26 is connected to the sand shovel drive assembly 32 through a sprocket mechanism. The sprocket mechanism has high transmission efficiency and accurate transmission ratio, which can ensure the stability of power transmission; a no-till machine bearing platform 6 is provided above the sand conveyor belt 21 to fix the no-till machine body and ensure the stability of the equipment during the sowing process.

[0024] The entire working process of the device is as follows: First, adjust the distance between the two sets of test bench modules 1 according to the wheel track of the no-tiller, place the no-tiller on the no-tiller bearing platform 6, and make the no-tiller wheels contact the wheel conveyor belt 41; start the motor 5, and the motor 5 drives the wheel conveyor belt roller 42 to rotate through the output shaft, driving the wheel conveyor belt 41 to run, simulating the driving action of the no-tiller; at the same time, the motor 5 drives the upper horizontal shaft 45 to rotate through the lower horizontal shaft 43 and the transmission shaft 44, thereby driving the sand upper conveyor belt roller 22 and the upper gear 26 to rotate. The upper gear 26 meshes with the lower gear 27, driving the sand lower conveyor belt roller 24 to rotate, so that the sand upper conveyor belt 21 and the sand lower conveyor belt roller 24 rotate, making the sand upper conveyor belt 21 and the sand lower conveyor belt roller 24 rotate, thus simulating the driving action of the no-tiller. The sand conveyor belt 23 operates synchronously; the upper gear 26 simultaneously drives the sand-collecting shovel drive assembly 32 to operate. The sand-collecting shovel 33 is driven by the sand-collecting shovel drive assembly 32 to circulate and rise and fall, lifting the sand in the sand recovery channel 31 to the sand delivery channel 34 and delivering it onto the sand upper conveyor belt 21, forming a continuous sand transmission surface. The no-till machine travels under the drive of the wheel conveyor belt 41 and performs seeding operations at the same time. After the seeds fall into the sand upper conveyor belt 21, they move to the rear end with the sand. After being separated by the seed screen 25, the seeds are collected to observe the seeding effect. The sand flows back to the sand recovery channel 31 through the sand lower conveyor belt 23, completing the cycle.

[0025] This invention achieves controllable and reusable simulated soil environment by setting up a circulating sand transport and lifting system, effectively solving the problems of unstable soil conditions, high testing costs, and low efficiency in traditional field testing. Through multi-component linkage design, it ensures the matching of the no-till machine's travel speed and sand transport speed, which can accurately simulate the sowing effect under different working conditions and improve the reliability of test data. The setting of adjustment mechanism and bearing platform enhances the versatility and stability of the device. The overall structure is compact and highly automated, providing strong support for the efficient testing and optimization design of no-till machine sowing performance.
