Description

A fixture for corn ear experiments or bare-hand threshing

technical field

The invention relates to the field of agricultural machinery, in particular to a fixing device for corn ear experiments or bare-hand threshing.

Background technique

Corn is not only the largest food crop in China, but also the food crop with the highest total output in the world. Therefore, experimental research on corn ears is necessary. Unavoidable in the test is the fixing of the ear of corn, and the existing equipment does not have a device dedicated to fixing the ear of corn, which cannot well complete the clamping effect on the ear of corn. And still be to carry out manual threshing to the ear of corn in the area of rural part, fix the ear of corn by hand and easily cause injury to hands in the process of threshing. However, when the processing and installation tools of existing mechanical parts are used in the fixing of corn ears, it is difficult to play a good fixing effect on corn ears, and it is difficult to reduce the damage of the threshing tool to the hand during manual threshing, especially in the experimental process. Determine more accurate data.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the defects in the prior art of experimenting or manual threshing of corn ears, which are easy to cause damage to hands and inaccurate experimental data due to lack of suitable fixing devices, and provide a kind of corn Fixture for ear experiments or bare-hand threshing.

The technical solution adopted by the present invention to solve the above problems is: a fixing device for corn ear experiments or bare-hand threshing, the fixing device includes a chassis and a clamp body installed on the chassis, the clamp body has two opposite There are a plurality of side plate holes distributed on the two side plates at equal intervals, and fastening bolts for fixing corn ears are installed in each side plate hole. Nuts on the outside for fastening the fastening bolts to the side panels.

In the present invention, the side plate holes are arranged in vertical strips, that is, the side plate holes on the side plates are a plurality of equidistant rectangular holes, which is convenient to adjust the clamping effect of the fastening bolts on the ears of corn; The end of the inner surface of the side plate is connected with a rubber sheet, which can protect the grain on the ear of corn from being damaged due to the extrusion of the fastening bolt.

The two side plates of the clamp body are fixed on a bottom plate, and a plurality of bottom plate holes are arranged on the bottom plate, and the clamp body is fixed on the chassis by bolt groups passing through the bottom plate holes.

The bottom of the chassis is provided with rollers for easy movement.

Beneficial effects: 1. The device is used to fix the ears of corn during the experiment, which can make it firmly fixed and facilitate experimental operations such as measurement of the ears of corn; when threshing the ears of corn with bare hands, the fixing device can avoid threshing tools 2. The side plate holes are arranged in a vertical strip shape, so that the fastening bolts can be adjusted up and down along the vertical direction of the side plate holes, and the clamping effect of the corn ear can be adjusted as required; 3. The fixed The device has universality and is convenient for fixing other crops for experimental operation.

Detailed ways

A kind of corn ear experiment as shown in Figure 1 and Fig. 2 or the fixing device that bare-hand threshing is used, comprise chassis 1 and the clip body 2 that is installed on the chassis 1, the bottom of chassis 1 is provided with roller 6, and clip body 2 has Two opposite side plates 20 are fixed on a bottom plate 22 . As shown in Figure 4, the bottom plate 22 of clamp body 2 is provided with four bottom plate holes 23 that are elongated. 23 to adjust the position forward and backward. Wherein, a plurality of side plate holes 21 are distributed at equal intervals on the two side plates 20 of the clamping body 2, and fastening bolts 3 for fixing corn ears 4 are all installed in each of the side plate holes 21, and the fastening bolts are covered with Nuts for fixing the fastening bolts on the side plates are respectively located on the inner and outer sides of the side plates, and the ends of the fastening bolts located on the inner surfaces of the side plates are connected with rubber sheets 7 .

The side plate holes 21 of the clamp body 2 in this device are all set in a vertical strip shape, that is, there are three equidistant rectangular holes on the clamp body 2, so that the fastening bolts 3 can be adjusted up and down to ensure the fixed position of the corn ear 4 for the centerline. And here is that fastening bolt 3 is fixed, and corn ear 4 is also adjustable left and right, guarantees the accuracy of next step measurement. In addition, a rubber sheet 7 is placed at the contact position between the fastening bolt 3 and the ear of corn 4 to protect the ear of corn 4 from being damaged by the extrusion of the fastening bolt 3 .

When utilizing this device to carry out experiments on corn ears, the center of the clamp body 2 is placed on a predetermined measuring point by adjusting the position of the bolt group in the bottom plate hole 23 in advance; then the corn ears are placed in the clamp body 2, so that the side The fastening bolts pierced in the side plate holes 21 of the plate 20 fix the ears of corn, adjust the position of the fastening bolts 3 in the side plate holes 21, so that the central axis of the clamped corn ears is on the measurement point; Perform the desired experimental manipulations on the corn cobs. When corn ears are manually threshed, the clamping method is as described above, the corn ears are clamped in the clamp body 2, and the corn ears exposed on the outside of the clamp body 2 are threshed.
