[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is active on connecting parts such as hinges, pins and short shafts.

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] Embodiment 1:

[0020] The following is combined with Figure 1-3 The present embodiment describes a field pulping machine, comprising: side plates, a guard plate connected between the two side plates, a pulping shaft rotatably connected in the two side plates, a pulping knife connected to the pulping shaft, the pulping knife having an L-shaped cross section, the inner surface of the pulping knife being able to coincide with the outer surface of the scraper, the scraper being connected to the inner wall of the guard plate, the inner surface of the pulping knife and the outer surface of the scraper being both curved surfaces, the axes of the two curved surfaces being both located on the axis of the pulping shaft;

[0021] The power drives the pulping shaft to rotate, and the pulping shaft drives the pulping knife to rotate to break the rice stubble and press it into the mud. When straw is entangled on the pulping knife, the pulping knife drives the straw to the scraper, and cooperates with the scraper to cut the straw, effectively preventing the straw from becoming thicker and thicker, resulting in poor pulping effect and corrosion of the pulping knife.

[0022] The scraper is connected to the inner wall of the guard plate through a support ear, the upper end of the scraper is hinged in the support ear, the support ear is connected to the inner wall of the guard plate, a ball groove is opened in the scraper, a rotating ball is slidably connected in the ball groove, all rotating balls are connected to a push-pull rod, one end of the push-pull rod is connected to the telescopic end of the hydraulic cylinder, and the fixed end of the hydraulic cylinder is connected to a side plate;

[0023] When it is necessary to adjust the gap between the pulping knife and the scraper, control the hydraulic cylinder to contract, the hydraulic cylinder drives the push-pull rod to move, the push-pull rod drives the rotating ball to slide in the ball groove, the rotating ball drives the scraper to rotate around the support ear through the ball groove, the scraper and pulping knife are no longer in contact, avoiding long-term friction and wear between the scraper and the pulping knife. When cleaning is needed, just adjust the gap smaller.

[0024] The lower end of the scraper is connected with a scraper pin, and the rotation range of the scraper pin with the support ear hinge shaft as the axis is tangent to the outer surface of the pulping shaft;

[0025] The scraper is controlled to rotate, which drives the scraper nail to rotate. Since the rotation range of the scraper nail with the support ear hinge shaft as the axis is tangent to the outer surface of the pulping shaft, the straw wrapped around the pulping shaft can be torn off and separated when the scraper nail rotates.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
