Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a circular circulating type deep scarifier friction and wear experimental device. BACKGROUND
[0002] Deep scarification is an important part of agricultural conservation tillage, which uses agricultural machinery such as a deep scarifier to loosen the soil, break the plough pan, improve the structure of the plough layer, and enhance the water storage and anti-drought and drainage capacity of the soil, which is beneficial to the growth of crops and improves the yield of crops. The main working part of the deep scarifier is the deep scarifier, and the shank and tip of the deep scarifier are subjected to strong friction of the soil layer during deep scarification, which is prone to wear and failure. Therefore, it is necessary to conduct friction and wear experiments on the deep scarifier to test the wear resistance of the deep scarifier and provide a basis and foundation for the development and improvement of the deep scarifier. Traditional friction and wear experiments are mostly carried out in the field or in a laboratory soil tank, but field experiments are easily affected by seasons, climate, etc., and the laboratory soil tank occupies a large area and has a complex structure, and is mostly linear testing. At present, there is a lack of a device with a simple structure and capable of conducting friction and wear experiments under soil conditions. SUMMARY
[0003] The utility model intends to provide a circular circulating type deep scarifier friction and wear experimental device to solve the problems of large area and complex structure of the laboratory soil tank.
[0004] In order to achieve the above purpose, the utility model provides a circular circulating type deep scarifier friction and wear experimental device, which comprises a soil tank and a soil tank vehicle, the soil tank is annular, the top end of the soil tank is provided with a soil tank track, the soil tank vehicle comprises a vehicle frame, track wheels running along the soil tank track, and a reduction motor for driving the track wheels to rotate, a directional slide rail is fixedly installed on the vehicle frame, a sliding block is slidably connected to the directional slide rail, a fixing frame is fixedly connected to the sliding block, a deep scarifier hanging frame is fixedly connected to the fixing frame, a pressure sensor is arranged between the fixing frame and the directional slide rail, one end of the pressure sensor is fixedly connected to the fixing frame, and the other end of the pressure sensor is fixedly connected to the fixing frame or the deep scarifier hanging frame.
[0005] The working principle and beneficial effects of the scheme are that: in the scheme, the soil is filled in the soil tank, the deep scarifier to be tested is connected to the deep scarifier hanging frame, and then the soil tank vehicle is placed on the soil tank track. The track wheels are driven to rotate by the reduction motor, so that the soil tank vehicle travels along the soil tank track. Moreover, when the soil tank vehicle travels to the turning place of the soil tank track, the track wheels can complete the turning like train wheels. In this way, the soil tank vehicle with the deep scarifier performs a cycle test in the soil condition. During the cycle test, the frictional resistance generated by the soil on the deep scarifier is converted into the pressure of the fixing frame on the pressure sensor, so that the operation resistance data of the deep scarifier are obtained. After the cycle number reaches the standard, the deep scarifier is taken out, and the friction condition of the soil on the deep scarifier is observed and detected, so that the wear resistance of the deep scarifier is evaluated.
[0006] In summary, the scheme has simple structure, small floor area, can perform a cycle friction and wear experiment in the soil condition, and can obtain the operation resistance data of the deep scarifier, thereby providing a basis and reference for the research and improvement of the deep scarifier.

[0008] In the scheme, the electromagnetic signal generator generates a sinusoidal signal, the electromagnetic wire generates a sinusoidal magnetic field after being electrified, interacts with the I-shaped inductor on the support, generates electromagnetic induction, and further generates an induced current. The electromagnetic signal is obtained after amplification. The electromagnetic induction data are determined by the strength change of the electromagnetic signal, the position of the soil tank vehicle is judged by the electromagnetic operation module, and the soil tank vehicle is controlled to complete the turning assistance. Specifically, when the soil tank vehicle travels to the turning place of the soil tank track, the electromotive forces induced by the left and right I-shaped inductors on the support are different: the induced electromotive force of the I-shaped inductor on the inner side of the arc is greater than that of the I-shaped inductor on the outer side of the arc. Accordingly, the soil tank vehicle is guided to turn.
[0009] Optionally, an infrared induction counter for detecting the cycle number of the soil tank vehicle is arranged above the soil tank.
[0010] In the scheme, the cycle number of the soil tank vehicle is counted automatically by the infrared induction counter, manual recording is avoided, and the workload of the experiment personnel is reduced.

The middle frame body is fixedly installed with a battery for supplying power to the reduction motor. The track wheel is installed on the lower frame body.
[0012] In the scheme, the track wheels are staggered with the directional slide rails, so that the test personnel can observe the working condition of the pressure sensor during the cycle test.

[0027] Embodiment one
[0028] The embodiment is basically as shown in Figure 1 , Figure 2 and Figure 3 : a circular circulating subsoiler friction and wear test device, including a soil tank 1 and a soil tank vehicle 2. The soil tank 1 is annular, and the top end of the soil tank 1 is welded with a soil tank track 3. The soil tank 1 is filled with soil, thereby providing a soil environment for the subsoiler 14 to be tested.
[0029] In combination with Figure 4 , Figure 5 and Figure 6 , the soil tank vehicle 2 includes a vehicle frame 4, track wheels 5 running along the soil tank track 3, and speed reducer motors 6 for driving the track wheels 5 to rotate. The vehicle frame 4 includes an upper layer frame body 401, a middle layer frame body 402, and a lower layer frame body 403, which are connected by a column body 404. The track wheels 5 are rotatably installed on the lower layer frame body 403 through a bogie 7. Specifically, in the embodiment, the number of track wheels 5 is four, and the structure of the track wheels 5 is the same as that of a train wheel. The track wheels 5 include a wheel body 501 and a rim 502. The wheel body 501 is conical, i.e., the outer diameter of the wheel body 501 gradually decreases in the direction away from the soil tank track 3. The track wheels 5 are rotatably installed on the bogie 7 through a shaft, and the bogie 7 is rotatably installed on the lower layer frame body 403. In this way, the track wheels 5 can freely rotate by a small amplitude relative to the vehicle frame 4. The four track wheels 5 are divided into two front track wheels and two rear track wheels. The number of speed reducer motors 6 is two, and the two speed reducer motors 6 are respectively used to drive the two rear track wheels. The speed reducer motors 6 are fixedly installed on the corresponding bogies 7 to adapt to the small amplitude rotation of the rear track wheels 5.
[0030] The upper surface of the middle shelf body 402 is fixedly provided with a battery 8 for supplying power to the speed reducer motor 6, and the bottom surface of the middle shelf body 402 is fixedly welded with a directional slide rail 9, the directional slide rail 9 is slidably connected with a sliding block 10, the sliding block 10 is integrally formed with a fixing frame 11, the bottom end of the fixing frame 11 is connected with a deep scarifier hanging bracket 12 through screws, and the lower shelf body 403 is provided with a passage for the deep scarifier hanging bracket 12 to penetrate. The deep scarifier hanging bracket 12 is provided with a plurality of mounting holes, so that the deep scarifier 14 to be tested can be connected to the deep scarifier hanging bracket 12 through bolts. In the embodiment, the number of mounting holes on the deep scarifier hanging bracket 12 is six.
[0031] In combination Figure 7 As shown, the fixing frame 11 and the directional slide rail 9 are provided with a pressure sensor 13, one end of the pressure sensor 13 is connected with the directional slide rail 9 through screws, and the other end of the pressure sensor 13 is connected with the fixing frame 11 through screws, so that the pressure applied by the fixing frame 11 to the pressure sensor 13 can be detected by the pressure sensor 13. In the embodiment, the model of the pressure sensor 13 is JLBS-1, which can be matched with an XMT808-I display (the display can be installed on the upper shelf body 401).
[0032] In specific use, the soil is filled in the soil tank 1, the deep scarifier 14 to be tested is installed on the deep scarifier hanging bracket 12 through bolts, and then the soil tank vehicle 2 is placed on the soil tank track 3, at this time, the deep scarifier 14 to be tested is in the soil. Subsequently, the speed reducer motor 6 is started to drive the corresponding track wheel 5 to rotate, so that the soil tank vehicle 2 travels along the soil tank track 3, when the soil tank vehicle 2 travels to the turning place of the soil tank track 3, the track wheel 5 turns to adapt to the soil tank track 3 (the flange 502 prevents the wheel body 501 from derailing), so that the soil tank vehicle 2 circulates on the soil tank track 3, and the circulation test of the deep scarifier 14 is realized.
[0033] In the process of the soil tank vehicle 2 traveling, the deep scarifier 14 is in the plowing state, and in the plowing process, the soil generates frictional resistance to the deep scarifier 14, the frictional resistance is transmitted to the deep scarifier hanging bracket 12, so that the fixing frame 11 has a movement trend of moving to the direction of the pressure sensor 13, thereby applying pressure to the pressure sensor 13, and the pressure sensor 13 detects the pressure received thereby (the pressure value detected by the pressure sensor 13 is displayed by the display), which is the frictional resistance received by the deep scarifier 14 in the plowing process. In this way, the plowing (operation) resistance of the deep scarifier 14 is detected by the pressure sensor 13, and the plowing resistance data of the deep scarifier 14 is obtained. When the circulation frequency of the soil tank vehicle 2 reaches the standard, the speed reducer motor 6 stops working, the soil tank vehicle 2 stops, the deep scarifier 14 is taken out, the frictional condition of the soil to the deep scarifier 14 is observed and detected, and the wear resistance of the deep scarifier 14 is evaluated.
[0034] In summary, the embodiment realizes the cyclic friction and wear test of the subsoiler 14, and obtains the plowing resistance data of the subsoiler 14, thereby providing a basis and evidence for the research and improvement of the subsoiler 14; and compared with the traditional laboratory soil tank 1 device, the device has simple structure and small floor area. In addition, the soil type in the soil tank 1 can be replaced according to actual needs to measure the plowing resistance and wear resistance of the subsoiler 14 under different soil conditions.

In the embodiment, the I-shaped inductor 17 selects Yahboo electromagnetic line patrol module, the electromagnetic operation module 18 selects OPA4197IPWR type, and the electromagnetic signal generator 21 selects Yahboo electromagnetic signal generator.
