Injection machine for trees

Abstract

The invention provides an injection machine for trees. The injection machine comprises a medicine storage box needle head component, a medicine pump component, a pump medicine connecting piece, a medicine pump pressure cylinder, a medicine inlet connecting piece, a needle inlet pressure cylinder and a clamping device. According to the injection machine provided by the invention, through optimizeddesign of each structure, compressed air or hydraulic oil is used as power, and an air cylinder or a hydraulic cylinder is used as a power device, so that reliable positioning of the machine on a treetrunk, rapid and stable needle insertion, precise control of a medicine amount, and rapid and stable needle withdrawal are realized; various processes are completed by control of a computer, so thata degree of automation is high; the medicine storage box needle head component of the injection machine is provided with an orientation device, so that an installation direction of a needle head is guaranteed, the direction of the needle head during operation is guaranteed to be not changed, and the operation effect is ensured; and a pressure sensor and a position sensor of the medicine storage box needle head component of the injection machine are designed, so that change of injection pressure and a needle head position during operation are monitored in real time, an occurrence of abnormal phenomena is prevented and avoided, and accuracy and an intelligence level of the operation of the device are improved.

Description

technical field [0001] The invention relates to the field of tree disease and insect pest control and nutrient solution injection equipment, in particular to a tree injection machine for injecting medicinal solution or nutrient solution into tree transporting tissues. Background technique [0002] As we all know, in the process of tree injection, if you want to stably and effectively inject the medicinal liquid or nutrient solution into the tree transporting tissue, firstly, the needle must be able to be inserted into the tree body quickly and stably, and the needle (including the machine) The whole) must remain stable (no shaking or external force); secondly, the feeding pressure must be large enough and stable; and the needle can be withdrawn quickly and stably. The existing tree injection facilities are mostly manually operated, which has many steps, high labor intensity, low work efficiency and poor reliability. Chinese Patent No. ZL95112833.7 discloses a tree injecti...
