Description
技术领域technical field
本发明涉及农业机械设计与制造领域，尤其是一种脱粒机。The invention relates to the field of agricultural machinery design and manufacture, in particular to a thresher.
背景技术Background technique
在农作物脱粒过程中，脱净率、破损率是主要的两项技术指标，较好的脱粒效果是较高的脱净率和较小的破损率。同时，为保证脱粒的顺利进行，脱粒机不堵塞是基本的要求。In the threshing process of crops, the cleaning rate and damage rate are the two main technical indicators. A better threshing effect is a higher cleaning rate and a smaller damage rate. At the same time, in order to ensure the smooth progress of threshing, it is the basic requirement that the threshing machine is not blocked.
影响脱净率和破损率的主要技术参数是滚筒的线速度和钉齿对物料的冲击角。滚筒的线速度越大脱净率和破损率越高。钉齿对物料的冲击角为900时破损率最大，小于900时冲击角越小，破损率越小。小于900、适当的冲击角具有最好的脱净率。The main technical parameters affecting the cleaning rate and breakage rate are the linear speed of the drum and the impact angle of the nail teeth on the material. The higher the line speed of the drum, the higher the cleaning rate and breakage rate. When the impact angle of the nail teeth on the material is 90 0 , the damage rate is the largest, and when the impact angle is less than 90 0 , the smaller the impact angle, the smaller the damage rate. Less than 90 0 , proper impact angle has the best cleaning rate.
脱粒对象即物料的品种不同、湿度不同，从提高脱净率、降低破损率的目标实现讲，需要不同的滚筒的线速度和钉齿对物料的冲击角。因此，优良的脱粒机为保证对物料品种和湿度的适应性，其滚筒的线速度和钉齿对籽料的冲击角应是可以调节的。The threshing objects are different types of materials and different humidity. From the perspective of achieving the goal of improving the cleaning rate and reducing the damage rate, different linear speeds of the drum and impact angles of the nail teeth on the material are required. Therefore, in order to ensure the adaptability to the material variety and humidity of a good thresher, the linear speed of the drum and the impact angle of the nail teeth on the seed material should be adjustable.
现行脱粒装置对滚筒线速度的调节，技术上简单，实践中也有较好的技术方案。而对钉齿对物料的冲击角的实现，则是根据生产中最为常见的品种和湿度设计一个最佳的、固定的冲击角。以钉齿式脱粒机为例，凹板和喂入台组件与机架固定联接，工作时滚筒的回转中心与凹板圆弧中心具有确定的相对位置，因此，制造安装完成后，滚筒上的钉齿对凹板的冲击角不能调节，这样，脱粒机的工作效果难以保证不同品种特别是不同湿度物料的脱净率和破损率。The current threshing device adjusts the linear velocity of the drum, which is technically simple and has a better technical solution in practice. The realization of the impact angle of the nail teeth on the material is to design an optimal and fixed impact angle according to the most common varieties and humidity in production. Taking the nail-tooth thresher as an example, the concave plate and the feeding table assembly are fixedly connected with the frame. During operation, the rotation center of the drum and the arc center of the concave plate have a definite relative position. Therefore, after the manufacturing and installation are completed, the The impact angle of the nail teeth on the concave plate cannot be adjusted, so the working effect of the threshing machine is difficult to ensure the cleaning rate and breakage rate of different varieties, especially materials with different humidity.
此外，脱粒机的堵塞经常是造成其停机检修的重要原因，影响脱粒机的工作效率。现有技术方案的效果也不十分理想。In addition, the blockage of the thresher is often an important reason for its shutdown and maintenance, which affects the working efficiency of the thresher. The effect of prior art scheme is not very ideal either.

具体实施方式Detailed ways
下面结合附图及实例，对本发明做进一步说明。The present invention will be further described below in conjunction with the accompanying drawings and examples.
如图1、图2、图3所示，本发明实施例冲击角可调式防堵塞脱粒机设有上下布置的滚筒2和喂入台组件，滚筒2可绕回转中心旋转，其外周设有多个钉齿，上方盖设有顶盖3。喂入台组件设有喂入台4，其在对应滚筒2的位置设有凹板1，凹板内部设有多个凸齿。凹板1和喂入台4通过四个滚轮14分别与两个滚动条型导轨5相连，并可沿条型导轨5平行移动。条型导轨5通过螺钉与机架固连。凹板1和喂入台4相对于滚筒回转中心向左移动时，滚筒2上的钉齿与凹板上更右侧的凸齿冲击，冲击角增大，脱粒机的脱净率提高，相应的破损率增大。从另一方面理解，凹板1和喂入台4相对于滚筒回转中心向左移动时，物料入口（左侧）增大而出口（右侧）减小，物料在脱粒机中的时间增加，因而脱净率提高，相应的破损率增大，结论相同。同理，当凹板1和喂入台4相对于滚筒回转中心向右移动时，滚筒上的钉齿与凹板上更左侧的凸齿冲击，冲击角减小，脱粒机的脱净率下降，相应的破损率减小。可见，通过改变凹板1和喂入台4与滚筒回转中心的相对位置，脱粒冲击角发生变化，使脱粒机对物料品种和湿度具有适应性，保证较好的脱粒效果。As shown in Fig. 1, Fig. 2 and Fig. 3, the anti-clogging thresher with adjustable impact angle according to the embodiment of the present invention is provided with a drum 2 arranged up and down and a feeding table assembly. a nail tooth, and the upper cover is provided with a top cover 3. The feeding table assembly is provided with a feeding table 4, which is provided with a concave plate 1 at a position corresponding to the roller 2, and a plurality of protruding teeth are arranged inside the concave plate. The concave plate 1 and the feeding platform 4 are respectively connected with two rolling guide rails 5 through four rollers 14, and can move in parallel along the strip guide rails 5. The strip guide rail 5 is fixedly connected with the frame by screws. When the concave plate 1 and the feeding table 4 move to the left relative to the center of rotation of the drum, the nail teeth on the drum 2 collide with the convex teeth on the right side of the concave plate, the impact angle increases, and the cleaning rate of the threshing machine increases, correspondingly increased breakage rate. On the other hand, when the concave plate 1 and the feeding table 4 move to the left relative to the center of rotation of the drum, the material inlet (left side) increases and the outlet (right side) decreases, and the time of the material in the thresher increases, Therefore, the removal rate increases, and the corresponding damage rate increases, and the conclusion is the same. In the same way, when the concave plate 1 and the feeding platform 4 move to the right relative to the center of rotation of the drum, the nail teeth on the drum impact with the convex teeth on the left side of the concave plate, the impact angle decreases, and the cleaning rate of the thresher Decrease, the corresponding breakage rate decreases. It can be seen that by changing the relative positions of the concave plate 1, the feeding platform 4 and the center of rotation of the drum, the threshing impact angle changes, making the threshing machine adaptable to the material variety and humidity, and ensuring a better threshing effect.
如图1，凹板1和喂入台4在滚动导轨5上的移动由镶嵌在滑块连接板15内的滑块11完成。滑块11设置于滑动导轨10中，一端连接移动式电磁马达12（也可以由液压或气动系统实现，但相对于电磁方式，液压或气动系统较为复杂，控制难度较大），另一端连接弹簧9，弹簧9通过弹簧固定螺钉8固定于位于滑动导轨10一端的弹簧连接板6上，弹簧连接板6通过连接板固定螺钉7固定于滑动导轨10上。当移动式电磁马达12获得一定量的电流时，其电磁力通过输出推杆克服弹簧9的阻力和脱粒工作力，推动滑块11在滑动导轨10内移动。移动式电磁马达12的输入电流越大，其输出力越大，弹簧压缩量越大，滑块11向左的移动量越大。调节电源开头13，即调节电磁马达12的输入电流量，从而调整滑块11的位置，推动凹板1和喂入台4左右移动，达到调整脱粒机脱粒冲击角之目的。当然，本发明不限于上述这种调节装置，本领域一般技术人员可在上述调节装置的启发下联想到其他调节方式，在此就不一一介绍了。As shown in Fig. 1, the movement of the concave plate 1 and the feeding platform 4 on the rolling guide rail 5 is completed by the slider 11 embedded in the slider connecting plate 15. The slider 11 is set in the sliding guide rail 10, one end is connected to the mobile electromagnetic motor 12 (it can also be realized by a hydraulic or pneumatic system, but compared with the electromagnetic method, the hydraulic or pneumatic system is more complicated and difficult to control), and the other end is connected to the spring 9. The spring 9 is fixed on the spring connecting plate 6 at one end of the sliding guide rail 10 through the spring fixing screw 8, and the spring connecting plate 6 is fixed on the sliding guide rail 10 through the connecting plate fixing screw 7. When the mobile electromagnetic motor 12 obtains a certain amount of current, its electromagnetic force overcomes the resistance of the spring 9 and the threshing working force through the output push rod, and pushes the slider 11 to move in the sliding guide rail 10 . The greater the input current of the movable electromagnetic motor 12, the greater its output force, the greater the spring compression, and the greater the leftward movement of the slider 11. Adjust the opening 13 of the power supply, that is, adjust the input current of the electromagnetic motor 12, thereby adjusting the position of the slider 11, pushing the concave plate 1 and the feeding table 4 to move left and right, and achieving the purpose of adjusting the threshing impact angle of the threshing machine. Of course, the present invention is not limited to the above-mentioned adjusting device, and those skilled in the art may think of other adjusting methods inspired by the above-mentioned adjusting device, which will not be introduced one by one here.
脱粒机工作时，脱粒力基本上作用在移动式电磁马达12上，由于电磁马达的输出力与其输入电流量相关，一定的输入电流，对应一定量的输出力。因此，当脱粒工作力出现脉动时（这种脉动实际工作中总是存在的），凹板1和喂入台4随之振动，该振动的存在，有效地抑制了脱粒机的堵塞发生，使该型脱粒机具备真实意义上的防堵塞功能。当堵塞倾向十分严重时，直接调节电磁马达的输入电流，推动凹板1和喂入台4向右移动，从而改变脱粒机的输入输出口的大小，对防止脱粒机堵塞更加有效。When the threshing machine is working, the threshing force basically acts on the mobile electromagnetic motor 12. Since the output force of the electromagnetic motor is related to its input current, a certain input current corresponds to a certain amount of output force. Therefore, when the threshing force pulsates (this kind of pulsation always exists in actual work), the concave plate 1 and the feeding platform 4 vibrate accordingly. The existence of this vibration effectively suppresses the clogging of the threshing machine, making the This type of thresher has a real anti-clogging function. When the clogging tendency is very serious, directly adjust the input current of the electromagnetic motor to push the concave plate 1 and the feeding platform 4 to move to the right, thereby changing the size of the input and output ports of the threshing machine, which is more effective in preventing the clogging of the threshing machine.
当脱粒工作负荷脉动量过大时，将造成凹板1和喂入台4的振动幅度加大，影响脱粒机的正常工作，此时，可以用锁紧螺钉16将滑块11固定在滑动导轨10上，很大程度上消除脱粒机的振动。在这种工况下，脱粒机的防堵塞功能就只能依靠调节电磁马达的输入电流，推动凹板1和喂入台4移动，从而改变脱粒机的输入输出口的大小实现。When the pulsation of the threshing work load is too large, the vibration amplitude of the concave plate 1 and the feeding table 4 will increase, which will affect the normal operation of the threshing machine. At this time, the sliding block 11 can be fixed on the sliding guide rail with the locking screw 16 10, to a large extent eliminate the vibration of the thresher. Under this working condition, the anti-clogging function of the threshing machine can only be achieved by adjusting the input current of the electromagnetic motor to push the concave plate 1 and the feeding table 4 to move, thereby changing the size of the input and output ports of the threshing machine.
