Description

一种红枣自动分级机构An automatic grading mechanism for red dates

技术领域technical field

本实用新型涉及红枣分级技术领域,具体而言是一种红枣自动分级机构。The utility model relates to the technical field of jujube grading, in particular to an automatic grading mechanism for jujubes.

背景技术Background technique

大枣筛选设备,用于大枣采摘后的集中分类筛选。大枣采摘后集中堆放于仓库或晒坝。由于不同大小的枣子,市场价格差别大。所以需要筛选设备来快速高效的筛选大枣。Jujube screening equipment is used for centralized classification and screening of jujubes after picking. After picking, the jujubes are piled up in warehouses or sunbathing dams. Due to the different sizes of dates, market prices vary greatly. Therefore, screening equipment is needed to screen jujubes quickly and efficiently.

对红枣进行分级处理的方法大致有两种,一种是依靠人工分级,易受到人的主观因素影响,造成分级的误差很大,效率低,还会增加工人与红枣的直接接触机会,影响食品的卫生安全。自动分级又分为机械式分级和光电式、基于机器视觉分级等三种。机械式分级多是根据红枣的外部尺寸进行设计,多利用机械机构的不同间隙,如滚筒式、滚杠式或者是筛孔式等,分级等级较单一,且在分级过程中容易造成破损。光电式是利用红枣通过光电感应器的时间来判断枣的宽度,从而进行分级,这种分级装置对外部环境要求相对较高,效率效果差。第三种是利用机器视觉采集红枣信息进行分级。There are roughly two methods for grading red dates. One is to rely on manual grading, which is easily affected by human subjective factors, resulting in large errors in grading and low efficiency. It will also increase the direct contact opportunities between workers and red dates, affecting food. health and safety. Automatic grading is divided into mechanical grading and photoelectric grading, based on machine vision grading and other three. Mechanical grading is mostly designed according to the external dimensions of red dates, and uses different gaps of mechanical mechanisms, such as drum type, roller type or sieve type, etc. The grading level is relatively simple, and it is easy to cause damage during the grading process. The photoelectric type uses the time that the red dates pass through the photoelectric sensor to judge the width of the dates, so as to classify them. This classification device has relatively high requirements on the external environment and poor efficiency. The third is to use machine vision to collect jujube information for grading.

对于追求更高附加值,就需要更精细的筛选方式。For the pursuit of higher added value, more refined screening methods are required.

现有的机械式分级普遍有以下缺点:The existing mechanical classification generally has the following shortcomings:

设备只能将大枣分为两类。如果想进行两类以上的筛选,需要串连输送带,对场地占用非常大,且上一级传到下一级后,大枣在下级输送带上分布不均,造成筛选效率低下。The equipment can only classify jujubes into two categories. If you want to carry out more than two types of screening, you need to connect conveyor belts in series, which takes up a lot of space, and after the upper level is passed to the next level, the jujubes are unevenly distributed on the lower level conveyor belt, resulting in low screening efficiency.

输送采用链传动,传输速度受限制,且生产过程噪声很大。The conveying adopts chain drive, the transmission speed is limited, and the production process is noisy.

分级速度较慢,执行机构结构复杂。The classification speed is slow, and the structure of the actuator is complex.

铲入大枣时将各种杂质一并送入筛选设备,而设备没有单独的去杂质设计,这样,会加大后面成品包装过程的工作量。When the jujube is shoveled, all kinds of impurities are sent to the screening equipment together, and the equipment does not have a separate impurity removal design, which will increase the workload of the packaging process of the finished product.

筛选过程大枣有重叠现象,为保证落料充分,需要保证输送带有较长的长度。During the screening process, the jujube has overlapping phenomenon. In order to ensure sufficient blanking, it is necessary to ensure that the conveyor belt has a long length.
