Technical Field

[0001] The utility model relates to the technical field of corn threshers that are anti-jamming, in particular to a corn thresher that is anti-jamming. Background Art

[0002] Corn thresher refers to a mechanical device for threshing corn ears. Corn thresher has the characteristics of high automation, strong safety, easy operation and low energy consumption.

[0003] For example, an anti-stuck corn thresher with the authorization announcement number "CN220556927U", the driving shaft is fixedly installed with a sticky roller at one end passing through a through hole and extending to the top of the guide plate on the outside, and the driving shaft is fixedly installed with a gear on the outside. The corn thresher, through the setting of the stripping mechanism and the cleaning mechanism, tries to clean the corn silk before threshing to avoid the corn silk getting stuck in the equipment, thereby significantly reducing the probability of the corn thresher getting stuck and improving the threshing efficiency. However, when the corn thresher is in use, a filter net is used at the bottom, and the detached corn kernels are easily stuck in the filter net. In addition, the corn thresher cannot clean the stuck corn kernels in time during operation, so the corn kernels will accumulate inside the corn thresher until the corn thresher fails and gets stuck, which reduces the threshing effect of the corn thresher and affects the normal use of the corn thresher. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] See also Figure 1-6 In the present embodiment, a corn thresher with an anti-stuck state includes an outer shell 1 and a feed port 4. The rear of the top of the outer shell 1 is connected to the bottom of the feed port 4. A vertical plate 5 is fixedly connected to the top of the front of the outer shell 1. The bottom of the inner wall of the outer shell 1 is connected to a threshing structure 2. Supports 6 are fixedly connected to the front and back of the left and right sides of the outer shell 1 respectively. The supports 6 support the outer shell 1. The bottoms of the multiple supports 6 are fixedly connected to a bottom plate 7. The inner wall of the vertical plate 5 is connected to a power structure 3. The top of the bottom plate 7 is fitted with a box body 8.

[0023] The threshing structure 2 includes a curved frame 201 and a straight plate 202. The bottom of the curved frame 201 fits with the bottom of the inner wall of the shell 1. The front and rear sides of the inner wall of the curved frame 201 are fixedly connected to the front and rear ends of multiple straight plates 202. The gaps between the multiple straight plates 202 can ensure that corn kernels fall, but corn cobs cannot fall. An arc plate 203 is fixedly connected to the front of the bottom of the curved frame 201. The left and right sides of the front of the arc plate 203 are respectively threadedly connected with screw rods 204. The front of the screw rod 204 is fixedly connected with a handle 205. The handle 205 is convenient for driving the screw rod 204 to rotate forward and backward. The rear of the outer wall of the screw rod 204 is threadedly connected to the front of the shell 1.

[0024] The bottom of the curved frame 201 is made to fit with the bottom of the inner wall of the outer shell 1 through the threshing structure 2 until the rear end face of the arc plate 203 fits with the front face of the outer shell 1, and then the handle 205 is held to make the screw 204 pass through the arc plate 203 from the right front to the rear and connect with the front thread of the outer shell 1 to complete the fixation of the curved frame 201. The curved frame 201 cooperates with the straight plate 202 to change the form of the original filter screen, which can avoid the accumulation of corn kernels causing the corn thresher to get stuck, thereby improving the threshing effect of the corn thresher and ensuring the normal use of the corn thresher.

[0025] A handle 9 is fixedly connected to the front of the box body 8, and the handle 9 is convenient for pulling the box body 8 forward and backward. A vibration motor 12 is fixedly connected to the upper outer side of the rear support 6, and the model of the vibration motor 12 is selected according to the use requirements. The power structure 3 includes a cylinder 301 and a ridge 302. The front of the outer wall of the cylinder 301 is rotatably connected to the inner wall of the vertical plate 5, and the rear of the outer wall of the cylinder 301 is rotatably connected to the rear of the inner wall of the outer shell 1. The cylinder 301 is subjected to force to rotate through the bearings behind the inner wall of the vertical plate 5 and the inner wall of the outer shell 1. The outer wall of the cylinder 301 is fixedly connected to the inner sides of multiple ridges 302, and the end of the cylinder 301 is fixedly connected to a rotating motor 303. The model of the rotating motor 303 is selected according to the use requirements. The outer wall of the rotating motor 303 is fixedly connected to a bracket 304, and the end of the bracket 304 is fixedly connected to the outer wall of the outer shell 1.

[0026] Working principle:

[0027] Corn thresher threshing structure installation:

[0028] The bottom of the curved frame 201 is made to fit with the bottom of the inner wall of the outer shell 1 until the rear end face of the arc plate 203 fits with the front face of the outer shell 1. Then, the handle 205 is held to allow the screw 204 to pass through the arc plate 203 from the right front to the rear and be connected with the front thread of the outer shell 1 to complete the fixation of the curved frame 201. The curved frame 201 cooperates with the straight plate 202 to change the form of the original filter screen, which can prevent the corn kernels from accumulating and causing the corn thresher to get stuck.

[0029] Corn thresher working:

[0030] The motor 303 is powered on and the output end of the motor 303 is clicked to rotate the cylinder 301. The rotating cylinder 301 rotates with the ridge 302, and then the corn is put into the shell 1 at the material port 4. At the same time, the vibration motor 12 works to generate vibration. Since the vibration motor 12 is located at the rear, the vibration force at the rear of the shell 1 is the strongest. At this time, the corn inside the shell 1 is vibrated and moves to the side with weaker vibration force. The rotating cylinder 301 with the ridge 302 moves the corn, so that the corn hits the straight plate 202. The impact of the corn will cause the corn kernels to break away and fall into the box 8 through the gap between the straight plates 202 for storage. The size of the corn cob is larger than the gap between the straight plates 202, and finally it is discharged in front of the shell 1. The handle 9 is held and pulled forward, so that the box 8 fits the top of the bottom plate 7 and moves forward, so that the box 8 is pulled out of the bottom of the shell 1, and then the corn kernels stored in the box 8 are taken out, and then the box 8 is pushed back.

[0031] Embodiment 2:

[0032] See also Figure 1-6 In this embodiment, a corn thresher that prevents jamming also includes round rods 10 and vertical cylinders 11. The bottom of the outer walls of the multiple round rods 10 are rotatably connected to the left and right sides of the top of the bottom plate 7, and the tops of the multiple round rods 10 are fixedly connected to the bottoms of the multiple vertical cylinders 11, and the outer walls of the multiple vertical cylinders 11 are all in contact with the outer wall of the box body 8.

[0033] Working principle:

[0034] When the box 8 moves forward and backward, due to the friction generated by the outer wall of the box 8, the vertical cylinder 11 cooperates with the round rod 10 to rotate on the top of the bottom plate 7. The round rod 10 and the vertical cylinder 11 restrict the box 8 to prevent the box 8 from deflecting on the top of the bottom plate 7.

[0035] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
