The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0024] It should be noted that, unless otherwise defined, all technical and scientific terms used in the specification are the same as those commonly understood by those skilled in the art of the present application. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0025] Please refer to Figure 1 , Figure 2 ,Figure 3 A plow type unloader of a conveyor, comprising a plow head 10, the front end of which is in the shape of a V with the front end being pointed, in the perspective of the top view, for contacting and guiding the bulk grain on the conveyor belt to the left and right sides, and the back end of which is in the shape of a plate. In the existing structure, the plow head 10 is mostly lifted above the conveyor belt under the drive of a hydraulic cylinder. The specific structure of the plow head 10 is the prior art, and will not be described in detail here.

[0026] Please refer to Figure 1 , Figure 2 In an embodiment, a first support plate 2 is arranged above the plow head 10, a pressure sensing system 18 is arranged between the plow head 10 and the first support plate 2 for measuring the pressure value when the plow head 10 contacts the conveyor belt.

[0027] Please refer to Figure 1 , Figure 2 A parallelogram linkage mechanism is arranged at the upper end of the first support plate 2, the parallelogram linkage mechanism comprises a driving rod 3 and a driven rod 6, the rotation axes of the driving rod 3 and the driven rod 6 are both in the horizontal direction, one end of the driving rod 3 is hingedly connected to the first support plate 11, the other end is fixedly connected to a driving shaft 4 in a direction parallel to the rotation axis of the driving rod 3, a unloader support 14 is further arranged, a driving motor 16 is arranged on the unloader support 14 for driving the driving shaft 4 to drive the driving rod 3 to rotate, one end of the driven rod 6 is hingedly connected to the first support plate 2, and the other end is hingedly connected to the unloader support 14.

[0028] Working principle: the driving motor 16 drives the plow head 10 to contact the conveyor belt, which will generate pressure, and the pressure value can be measured by the pressure sensing system 18, after multiple tests on the pressure value, the pressure value interval at which the plow head 10 can completely unload (cleanly unload) can be determined to provide (reference) data support for the position adjustment of the plow head 10, effectively improving the controllability of the distance between the plow head 10 and the conveyor belt, so that the distance between the conveyor belt and the plow head 10 is neither too large nor too small, which can not only cleanly unload the bulk grain and improve the unloading effect, but also prevent the plow head 10 from being pressed on the running conveyor belt and damaging the conveyor belt. Under the drive of the driving motor 16, the position (height) of the plow head 10 is adjusted by the structure of the rotation of the driving rod 3 and the driven rod 6, which has high structural stability and higher precision compared with the hydraulic cylinder drive, so that the accuracy of the position adjustment of the plow head 10 is higher.

[0029] Please refer to Figure 1In one embodiment, the pressure sensing system 18 comprises a pressure sensor 19 fixedly installed on the upper end of the plow head 10 and a pressure rod 20 vertically installed on the first support plate 2, the pressure rod 20 being located at the upper end of the pressure sensor 19 and in contact with the pressure sensing element (sensitive element) of the pressure sensor 19. Further, the plow head 10 and the first support plate 2 are connected by a bolt 11 (or a pin shaft), the lower end of the bolt 11 (or the pin shaft) being welded to the plow head 10, the bolt 11 (or the pin shaft) vertically upwardly penetrating the first support plate 2 and being hung on the first support plate 2 by a nut (or a pin cap). Since the pressure rod 20 is in abutment with the pressure sensor 19, the pressure value can be measured and the overall structure is relatively stable. Further, the pressure sensor 19 is connected to the computer in the central control room, so that the measured pressure value can be observed in real time on the computer. This arrangement is relatively easy to implement.

[0030] Please refer to Figure 2 In one embodiment, a driving gear 5 is fixedly installed on the driving shaft 4, the central axis of the driving gear 5 coinciding with the driving shaft 4, and a driven gear 17 is fixedly connected to the output shaft of the driving motor 16, the driving gear 5 being engaged with the driven gear 17.

Further, the bottom surface of the additional plow head 1 can be slightly higher than the bottom surface of the plow head 10 or can be flush with the bottom surface of the plow head 10. This arrangement enables the additional plow head 1 to first unload a part of the bulk grain in front, helping the plow head 10 to share the unloading pressure, and achieving better effect.

The lower end of the front side of the additional plow head 1 is attached with a second wear plate 9, and the second wear plate 9 also has two, respectively attached to the lower end of the V-shaped two sides of the front end of the additional plow head 1, to improve the wear resistance of this place.

In this way, when they reach the service life or are damaged, they can be removed and replaced. Preferably, the first wear plate 12 and the second wear plate 9 are detachable by threaded coupling. In this way, the structure is easy to realize and the operation is relatively simple.

[0034] Please refer to Figure 1 , Figure 2 In one embodiment, the upper end of the first support plate 2 is further provided with a reinforcing rod 7, and the reinforcing rod 7 is located in front of the driving rod 3.
