Description

Technical Field

[0001] The utility model relates to the field of walnut shelling, in particular to a quantitative extrusion type walnut shelling device. Background Art

[0002] Walnuts are rich in various bioactive substances and have special physiological effects on the human body. Their unique taste is widely loved. With the increasing annual output of walnuts, it is particularly important to improve the quality of shelling and processing. However, due to the protruding edges, numerous cracks, small internal gaps in the walnut shell, and the existence of multiple interlocking partitions in the walnut shell, it is very challenging to obtain complete walnut kernels during the shelling process. For a long time, manual labor has been mainly used for walnut shelling to obtain whole kernels. This method has high labor intensity, low efficiency, high economic cost, and it is difficult to ensure hygiene. Existing mechanical shelling has problems such as incomplete shelling, low whole kernel rate, and high broken kernel rate. Currently, few devices can achieve quantitative and multi-station combined shelling. Therefore, there is currently a lack of a quantitative extrusion type walnut shelling device to achieve high-quality shelling with multi-station combination. Summary of the Utility Model

[0003] To solve the above problems, the utility model provides a quantitative extrusion type walnut shelling device, which can realize the function of quantitative extrusion shelling through the mutual cooperation of multiple structures.

[0004] To achieve the above object, the present application provides the following technical solutions:

[0005] A quantitative extrusion type walnut shelling device, characterized in that it includes a shelling frame, an extrusion structure, a pulling-back structure, a shelling roller, an extrusion cam, an extrusion camshaft, a transmission sprocket, a driving dial, and a driven sprocket wheel;

[0006] The shelling frame is the overall support, and its two ends are welded to the main body of the walnut shelling machine. A bearing seat for installing the extrusion camshaft is fixed at the upper end, and threaded holes for installing a spring mounting plate are provided at the lower end;

Five groups of extrusion heads are installed on the five groups of cylinders of the extrusion rod through threaded connection;

[0008] The pulling-back structure includes a spring mounting block, a spring mounting bolt, a pulling-back spring, and a spring mounting plate; the upper end of the spring mounting block has a threaded hole, and it is fixed to the spring mounting plate through the spring mounting bolt, and a spring bayonet for hooking the upper end of the pulling-back spring is provided;

[0009] There are two sets of the extrusion cams, which are installed on both sides of the extrusion camshaft and contact with the transmission rollers; the transmission sprocket is the power source of the whole device and drives the extrusion camshaft to rotate; the active dial is installed on the extrusion camshaft and is driven by the extrusion camshaft to rotate; the driven grooved pulley is installed at the long end of the shell-breaking roller, is driven by the active dial (28) to rotate, and drives the shell-breaking roller to rotate.

[0010] Preferably, the movement of the extrusion structure during operation is the up-and-down movement in the vertical direction. The pulling-back structure uses the pulling force of five groups of pulling-back springs to closely fit the transmission roller at the upper end of the extrusion structure with the extrusion cam, thereby converting the rotational movement of the extrusion cam into the up-and-down movement of the extrusion head.

[0011] Preferably, the convex contour of the extrusion cam is designed with four strokes: the pushing stroke, the far rest stroke, the return stroke, and the near rest stroke, which respectively correspond to the four states of the pressure head of the extrusion structure moving downward, the pressure head staying still, the pressure head retracting, and the pressure head being stationary.

[0012] Preferably, the extrusion head is provided with a spring bayonet that can be hooked by the pulling-back spring. There are two sets of symmetrical extrusion inclined planes on the part that contacts the walnut. The set of extrusion inclined planes with a larger area is the main part that applies the extrusion force to the walnut, and the set of extrusion inclined planes with a smaller area plays an auxiliary extrusion role and prevents the walnut from slipping out.

[0013] Preferably, the driven grooved pulley has a total of eight grooves. Under the action of the active dial, it performs an intermittent movement of rotating 1 / 8 of a circle each time, and coordinates with the up-and-down movement of the extrusion structure to complete the working strokes of feeding, discharging, and shell-breaking.

[0014] Preferably, the main body part of the shell-breaking roller is a regular octagon, corresponding to eight extrusion surfaces respectively. Each extrusion plane is provided with five evenly distributed notch openings for placing walnuts. The size of the notch openings is slightly larger than that of the walnuts, and two groups of inclined planes that are beneficial for extrusion and baffles for preventing the walnuts from falling out are provided.

[0015] According to a quantitative extrusion type walnut shell-breaking device provided by the present application, the following functions can be achieved:

[0016] 1.

[0017] 2. The power is input by the transmission sprocket, transmitted to the extrusion cam via the extrusion camshaft. The extrusion cam is designed with four strokes: the pushing stroke, the far rest stroke, the return stroke, and the near rest stroke, and can realize the four states of the pressure head of the extrusion structure moving downward, the pressure head staying still, the pressure head retracting, and the pressure head being stationary;

[0018] 3. This application has three working strokes: feeding, discharging, and shell-breaking. When in the feeding and discharging strokes, the extrusion structure is in a state where the pressing head is stationary. At this time, the shell-breaking roller rotates 1 / 8 of a circle, feeding new walnuts and discharging the walnuts whose shell-breaking is completed, thus completing the feeding of walnuts to be shell-broken and the discharging of shell-broken walnuts. When in the shell-breaking stroke, the shell-breaking roller intermittently stops. At this time, the extrusion structure goes through three states: the pressing head moves downward, the pressing head remains stationary, and the pressing head retracts, thus completing the shell-breaking and retracting of the pressing head. Therefore, with the coordination of multiple parts, this application can complete the three strokes of feeding, shell-breaking, and discharging.

[0019] 4. The extrusion head for extruding walnuts and the notches of the shell-breaking roller are provided with a total of four groups of extrusion inclined surfaces, which can extrude walnuts from multiple directions, further improving the degree of fragmentation of the walnut shell and preventing the walnuts from being ejected under pressure.

[0020] In summary, a quantitative extrusion type walnut shell-breaking device provided by the present utility model can achieve high-quality shell-breaking with the combination of multiple working positions. Description of the Drawings
