Description

Technical Field

[0001] The invention relates to the technical field of rotary tillers, in particular to a rotary tiller machine running-in test bench. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete plowing and harrowing operations. It is widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, making it easier for the seeder to operate and providing a good seed bed for later sowing. It is divided into three types according to the configuration of the rotary tiller shaft: horizontal shaft, vertical shaft and inclined shaft. Correct use and adjustment of the rotary tiller is very important to maintain its good technical condition and ensure the quality of tillage.

[0003] In order to cooperate with subsequent processes such as lubrication of the rotary tiller, most existing rotary tiller running-in test benches use idling rotary tiller blades to test them. They cannot be combined with rotary tillage work tests of the rotary tiller in the soil, resulting in a certain error between the obtained test data and the actual working data of the rotary tiller blades.

[0004] As the test time goes by, the soil inside the equipment will splash around as the knife roller rotates, causing the soil inside the equipment to become less and less. The staff is required to manually collect and recycle the soil, which greatly increases the workload of the staff.

[0026] The present invention provides a rotary tillage machine running-in test bench. Compared with the prior art, it has the following beneficial effects:

[0027] (1) When the rotary tiller needs to be tested, the driving motor, transmission shaft, clamping bin, electric push rod, clamping plate, rotary tiller, mud storage box and limit spring can be used to reduce the vibration of the mud storage box while testing the rotary tiller, so as to prevent the mud in the mud storage box from flying out due to excessive amplitude when the rotary tiller rotates, thereby improving the accuracy of the test data of the rotary tiller.

[0028] (2) In the rotary tiller running-in test bench, when the rotary tiller is tested inside the mud storage box, the rotation of the rotary tiller will cause the mud inside the mud storage box to splash and hit the shock-absorbing mechanism, causing it to vibrate. Through the cooperation of the mud guard, the limit vertical plate, the telescopic soft air pipe, the air pump, the connecting air pipe, the air hammer, the mud storage box and the limit spring, the mud brought out by the rotary tiller can be blocked and collected back into the mud storage box. The mud guard can also be knocked to prevent the mud from staying on the surface of the mud guard, resulting in too little mud inside the mud storage box, causing the rotary tiller to idle and affecting the test data of the rotary tiller.

[0029] (3) In the rotary tillage machine running-in test bench, when the mud guard collects the soil back into the mud storage box, the mud guard, the mud storage box, the limit spring, the movable plate, the telescopic rod and the first return spring can cooperate to evenly disperse the soil collected by the mud guard inside the mud storage box when the mud storage box vibrates. At the same time, when the soil inside the mud storage box decreases, the mud storage box can be raised so that the rotary tiller can continue to be tested in the soil inside the mud storage box, thereby preventing the soil from being discharged from the side wall of the mud storage box and preventing the rotary tiller from idling inside the mud storage box.

[0058] Embodiment 3

[0059] See also Figure 6-Figure 7 , this embodiment provides a technical solution based on the first embodiment: the vibration mechanism 6 includes a slide rail 60, one side of the inner wall of the fixed plate 7 is fixedly connected to one side of the slide rail 60, the slide rail 60 is slidably connected to a mud guard 61 through a slider, one side of the inner wall of the fixed plate 7 is fixedly connected to a limiting vertical plate 62, a side wall of the mud storage box 50 is fixedly connected to a telescopic soft air pipe 63, one end of the telescopic soft air pipe 63 is connected to an air pump 64, the top of the air pump 64 is connected to a connecting air pipe 65, the side of the connecting air pipe 65 away from the air pump 64 is connected to an air hammer 67, the bottom of the air pump 64 is slidably connected to a connecting plate 66, the side wall of the mud guard 61 is rotatably connected to one side of the limiting vertical plate 62, the bottom of the limiting vertical plate 62 is slidably connected to the top of the mud storage box 50, and one side of the connecting plate 66 is fixedly connected to the side wall of the sliding box 1;

[0060] It should be noted that when the rotary tiller 44 rotates inside the mud storage box 50, the soil will be thrown out in the direction of rotation. The mud guard 61 will block the thrown soil and slide it into the mud storage box 50. When the mud storage box 50 vibrates toward the side away from the fixed plate 7, the telescopic soft air pipe 63, the air pump 64, and the connecting air pipe 65 drive the air hammer 67 to move and hit the surface of the mud guard 61.

[0061] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0062] During operation, the staff member moves the rotary tiller 44 to be inspected into the clamping chamber 41 through the internal through hole of the fixing frame 45, and the rotary tiller 44 hits the trigger switch 411, and the electric push rod 42 is started to drive the clamping plate 43 to clamp and fix the rotary tiller 44. After the clamping chamber 41 and the fixing frame 45 have fixed the rotary tiller 44, the electric slide rail 46 drives the sliding plate 47 to move until one side of the rotary tiller 44 enters the internal through hole of the sliding plate 47 to further fix the rotary tiller 44, so as to prevent the rotary tiller 44 from falling off during the inspection process, thereby improving the safety of the device and, at the same time, inspecting rotary tillers 44 of different specifications to expand the working range of the device, and starting the driving motor 3. The driving motor 3 drives the rotary tiller 44 to rotate through the transmission shaft 40 and the clamping chamber 41, and the detection device 48 detects and records various data when the rotary tiller 44 rotates;

When the rotary tiller 44 rotates inside the mud storage box 50, it will drive the soil blocks to splash and hit the side wall of the transmission shaft 40. The setting of multiple limit springs 51 can limit the mud storage box 50 to prevent it from tipping over. As time goes by, the mud inside the mud storage box 50 will be reduced due to various factors. The first return spring 54 drives the movable plate 52 to rise, and the movable plate 52 drives the mud storage box 50 to rise, so as to avoid the mud inside the mud storage box 50 being reduced and causing the rotary tiller 44 to idle, affecting the detection data, and the rotary tiller 44 drives the sliding limit plate 57 to press down to limit the rotary tiller 44, while preventing the mud from being discharged from the side wall of the mud storage box 50.

[0064] When the rotary tiller 44 rotates inside the mud box 50, the soil will be thrown out in the direction of rotation. The mud guard 61 will block the thrown soil and slide it into the mud box 50. When the mud box 50 vibrates toward the side away from the fixed plate 7, the telescopic soft air pipe 63, the air pump 64, and the connecting air pipe 65 drive the air hammer 67 to move and hit the surface of the mud guard 61. When the mud box 50 vibrates close to the fixed plate 7, the air pump 64 contracts and transports the internal gas to the air hammer 67 through the air pump 64 and the connecting air pipe 65, so that the air hammer 67 becomes larger and hits the mud guard 61, so that the soil will not accumulate on the surface of the mud guard 61, avoiding the soil from splashing everywhere, and there is no need for the staff to manually recover it, thereby reducing the labor intensity of the staff and improving the degree of automation of the device.
